I started thinking about this last night and the costs of the blue ray or HD burners speculated to be around $2000 is another thing pushing the cost of the hvx200 way past the initial $6000. I already own a Wiebetech TrayDock, which is basically a firewire hard drive that you can put your own hard drives into. These days you can buy a 250 gig drive for around $100. Considering that it probably has closer to 240 gigs of actually storage, that's about 10 hours of 720p24 material. Compare that to 10 x 1 hour HDV tapes at around $10 a piece and it's basically a dead heat.
I was planning on going this route anyway, so I'm not sure how Blue Ray burners would help me. I already get old VHS or mini Beta SP tape cases and store my old hard drives in them, so perhaps this could be a solution ona larger scale for the hvx200.
I'm very good at missing something obvious, so perhaps I'm missing the advantage of the Blue Ray. But, presently, could someone explain to me how the HVX200 would be more expensive to run than an HDV can in this setup (other than the initial cost of the TrayDock)? Unless I'm missing something, it seems the same to me.

My guess is you're right. You would probably want to double back-up so if one drive dies you are safe, but that is still pretty inexpensive. Its more of a hassle to hand off drives to a client like this, but if people get used to it, it makes sense to me.
I assume that this is the workflow for now at least.
I think most people like the idea of getting off hard drives to something optical and smaller but until that comes around, the tray dock or any other hot swap device is a the cheapest solution.
Not too hard really.

Unless I'm missing something, it seems the same to me.

The biggest problem with the HVX200 is the cost of the storage required to capture the video you need out in the field in the first place. But setting that aside, let's examine your archiving cost estimate more carefully. As Leonard pointed out you'll need to make two copies of anything important, since you won't have a tape backup copy and hard drives are inherently unreliable. So now you need two 250 GB drives at $100 each to back up about 13 hours of 720/24pn video, which works out to around $15/hour -- plus the value of your time required to transfer and duplicate the footage. (But let's call that a wash compared to capturing raw footage from HDV tapes.) Most people using HDV cameras aren't bothering with the expensive HDV tapes, they're using regular miniDV tapes costing ~$3-5/hour. If they then capture that footage to the same 250 GB hard drives you're talking about, that costs them another $5 or so per hour of source footage, so a total of let's say $10 per hour.

So for each hour of footage you shoot on the HVX200 at the lowest typical bandwidth setting, your archiving costs are at least 50% higher than shooting HDV, and that's assuming the HDV shooter keeps the hard drive copy of their footage. (Which most don't since the tape backup copy is sufficiently reliable.) If you shoot full-bandwidth DVCProHD, your archiving costs jump to $37.50/hour, or almost four times the cost per hour of HDV. (Or eight times as much as for HDV shooters who only keep the master tape after finishing a project.) That's a potentially significant cost difference if you shoot at least 100 or more hours of footge per year.

Well true, the cost of p2 cards etc is a whole another thing to consider. But, that's interesting, there's always different ways of playing with numbers. I actually thought most people were using the HDV tapes, but if not then that does make a difference. I was always told though that the 1st thing you should do when you shoot is make a backup of your tapes, so I thought this too might be a wash. But, I know very few people who actually do that, so that might be unfair and this may be another problem of the comparison.
Still, in my own observation, it's miles that kills hard drives rather than age, so I feel pretty comfortable on short projects using a drive for a few months to possibly a year then putting it in storage. Would I do this on long projects, like a feature? I don't know, probably not. An extra backup hard drive there would probably be a good idea.
Anyway, this was kind of food for thought.

Or you could look at it this way: for many people the cost of HDV tapes isn't going to exceed the cost of P2 cards or Firestore hard drives for the HVX200, so take the initial recording cost out of the equation. Now the cost of archiving anything shot in HDV is inherently cheaper than archiving anything shot on the HVX200, since the storage requirements are smaller for a given amount of recording time. And since you can use DTE drives to eliminate the need for tapes with HDV, there's no advantage to the HVX200 there either.

I don't see much point in comparing costs for the HVX200 to HDV. If you really want what the HVX200 has to offer then you shouldn't be too concerned about the cost, except compared to other options for shooting and processing DVCProHD. If you care about cost, HDV is the way to go.

The Blue-ray route is very expensive although costs will obviously come down. One things that doesn't get mentioned frequently is that the blank disks are VERY expensive, around $90 each in small quantities. That's not any better than archiving via DLT. And at this point Blue-ray is notorious for the high failure rate of the finished DVDs. The large DVD duplicators are all concerned about the duplication costs for Blue-ray. On the other hand HD-DVD, an extension of the existing format, is easier. That is one of the reasons the computer industry is behind HD-DVD over Blue-ray: cheaper burners, cheaper media and sooner to be on the market at reasonable prices.

Personally, I plan for now to go with the hard drive option but expect to be able to go to HD-DVD later in the year.

I don't really get that post. It was pretty much taken as a given that HDV would be cheaper to use and archive.
But as far as comparing the costs, man that's standard operating proceedure for companies of any size. You weigh the pluses and minuses of the various options and the costs associated with each. Something might be out of your range or it might not, depending on different solutions. My only point posting this was that the cost difference might not be as much as had been previously believed when comparing the 2 formats. Depending on your workflow, it may or may not be, but I don't understand dismissing it out of hand like that.

Sorry, I didn't mean to make light of what you were trying to say, but when you add up all the costs the HVX200 simply can't compete with HDV for now. It is interesting that the cost of hard drive space has dropped to the point where archiving DVCProHD footage isn't impossibly expensive, but it's still ~$1500 for 100 hours of low-bandwidth footage or ~$3750 for 100 hours of full-bandwidth material. Compare that to as little as $300 for 100 hours worth of HDV recording on miniDV tape, and HDV wins by a mile in any sensible cost comparison.

This is the bleeding edge.. when I got my digital rebel the first month it was out, I paid 550 bucks for a one gig slow poke CF card... and did one job with the digital camera and figured it was worth every cent because of the workflow and immediacy.

I will be shooting low volume high deadline stuff with this camera and hope to never shoot tape again. I don't even plan on recording to P2 initally. I'll be streaming to a laptop and then handing off master quality DVDs to the client as well as a FCP project file.

Great shifts in thinking will be costly...

I jumped into this thread hoping it would rattle out some ideas on long term storage for HVX footage ... no offense, but I didn't think the original intent was to explore HDV vs. HVX expenses.

So, any ideas out there from people who are currently using an HVX and are dealing with the reality of long-term storage?

Or, if I'm off here, should I start a different thread? Thanks!

Well, that was the original intention of this thread... I think. But it seems a lot of forum members have been crapping in HVX threads lately with HDV comparisons. Anyway...

So, any ideas out there from people who are currently using an HVX and are dealing with the reality of long-term storage?

For right now, the most reliable and cost-effective means of backing up, long-term storage or archival of your HVX footage is tape. No question about it. There are several options for tape drives and formats and it can admittedly get very confusing. The primary formats available are DLT, LTO and AIT and there are several versions of each. A good tape drive which can store 160GB of uncompressed data (always go off the uncompressed number) will run about $500 to $1000 with tapes in the $20 range. After a dozen tapes or so, the numbers will start to work in favor of tape and it will gradually prove to be cheaper than hard drive storage. But even at the same or similar price point, I would trust a tape, more than a hard drive as it doesn't have all the internal parts, heads, motor, etc... that can fail.

If you're only shooting 20GB or video each week or so, then take a look at simply backing up to DVD-R. A 4GB P2 card backs up perfectly to a single layer DVD-R disc. An 8GB P2 can span 2 discs with most decent disc burning/backup software. Good quality DVD-R media can be had in bulk for $0.35 per disc for 8X capable. There are 16X capable discs out there, but I have yet to find any that have a 100% burn rate and cost under $0.80 per disc.

BluRay and HD-DVD seem like a good format of choice for backup. However, they won't be cost-effective for initial buyers and just like DVD-R and CD-R it will take a while for prices to settle down. Probably a year or two before the first major price drop. Drives will start off at $995 MSRP and media will be initially priced at < $20 for single layer HD-DVD ($65 for dual-layer). BluRay will be < $50 for single layer and about $90 for dual layer. Ouch.

That pretty well sums it up. Personally, I would look into one of the new LTO-3 tape drives. They use the LTO-3 tapes which store 400GB uncompressed and have a transfer rate of 40~80MB/sec if your system can handle it. Drives are a bit pricey, but at about $75 to $95 per tape (the 400GB ones), that's roughly 1/4 the cost of HDD storage. If you will be doing a significant amount of archiving, that tape drive could pay for itself relatively quick compared to just buying hard drives to back up your stuff.

Some of the newer SDLT tape units from Quantum are worth looking into as well.

I have a feeling this is going to be very much like a rerun of VHS vs Beta, with HD-DVD playing the part of VHS and BluRay playing Beta. I'd almost bet the HD-DVD format wins in the consumer marketplace, and Sony, with BluRay, once again winds up with the higher end video production industry market.

The original premise of this thread was that archiving footage from an HVX200 could somehow be as cost-effective as shooting in HDV, which calls for a direct comparison between the two formats. I've tried to keep my comments in that regard straightforward and to the point, so please don't interpret them as crapping on the Panny camera. As I've noted in other discussions, I think the HVX200 has a lot of potential for those people who can find a way to work it.

Yeah, re-reading this thread, I guess the HDV comparison was present right from the very first post. As for the thread crapping, I wasn't targeting you in any way. You have been very straight-forward with such issues. There has been a lot of whining in some other threads though by others and that's what I was thinking of... Stuff like people chiming in out of nowhere with incomplete and irrelevent posts like "the HVX sucks because it can't do HDV".

But keeping this thread on topic... I don't think there is any way to squeeze HVX backup options into a DV (HDV) price model. This is also going to apply to any other new cameras coming out that use tapeless recording, be it solid state, HDD or optical disc for their primary media. Obviously the situation will improve with time, but how much time is anyones' guess.

FWIW, I think one of the best HVX backup/archive solutions right now in terms of cost, and ease of use would be the Exabyte VXA-2 unit that attaches via FireWire. It can be purchased for about $1K and includes Dantz Retrospect software (good stuff) and a tape. Each tape holds a native 160GB and going rate for tapes is about $28 purchased individually, as low as $20 in reasonable bulk packs (like 25 count). Right now, the best price | capacity ratio for HDDs is at about the 250~300GB mark or about $0.38 per gigabyte (roughtly $96 for 250GB for a quality drive). This Exabyte firewire unit plus a box of 25 tapes at $22 per tape (plus the unit includes a free tape) figures out to $0.37 per gigabyte for those 26 tapes. Oh and if anyone is wondering, those 26 tapes hold 4160GB, or the equivalent of 520 8GB P2 cards (over 173 hours of 720pn24 footage). Top quality DV tape at $4 per tape will cost $696... Making the price difference about $854 between VXA-2 archiving DVCPROHD 720pn24 as compared to HDV or DV.

Now here's the kicker... Another box of $25 VXA-2 tapes will cost about $550 and will provide storage for 166.6 hours of 720pn24. To shoot that same amount of time to miniDV tape will cost about $668 using $4 tapes. So VXA-2 is about $0.70 per hour cheaper than DV tape in terms of video storage costs. The break-even point for equipment costs with the VXA tape system vs. HDV would be somewhere around 1430 hours of video (yikes!).

So, not as cheap as miniDV tape when considering the investment as a whole. But tape drives are probably the most logical and cost-effective solution for those of us who are traveling the HVX road. Besides, the tape system can be used for all other backups. And, if you do use it enough to reach tape #215, that's the magic number where this system should have repaid its investment (assuming it was a cash purchase to begin with) and from there on out will save money vs. DV tape. ...By that time it will probably be worn-out anyway and you'll need a new drive. Heh. :)

The first Blue Ray recorders from Pioneer are already on sale at Hong-Kong at retail price of 1000 USD.

TDK blu-ray discs sell for 200HKD each (20 gb)

I'm going to check out my friends drive in a couple of days. I'll probably order one myself! I'm not sure where I'll play back the videos, tough... I really wanted to see HD footage on a HDTV, and not on a computer monitor or something connected to my PC...

Be careful with those drives... There are a few that keep showing up on eBay and in various markets in Japan too. However, currently available BluRay and HD-DVD drives/players are all using beta firmware as the official release is still March 27 for HD-DVD and May 24 for BluRay. Sony and Samsung have both hinted that these grey market players will be incompatible with official release movie titles.

I'm going to check out my friends drive in a couple of days. I'll probably order one myself! I'm not sure where I'll play back the videos, tough... I really wanted to see HD footage on a HDTV, and not on a computer monitor or something connected to my PC...

For a player, I'm going to wait until the Samsung, LG and Marantz dual-format players go on sale. That should be sometime this summer and then I don't have to play the format game with my home theatre. As for computer drives, I already have a Toshiba HD-DVD drive for my PC on order and should have it on the 27th. I will also pick up a BluRay drive in May as I plan to be able to offer content on both types of media.

This depends on the type of tape, the drive and the host interface. Some newer tape systems like LTO-3 can deliver up to 80MB/s (640Mbps)! More common tape systems like the LTO-2, VXA-2, SDLT-3 hover between 10 and 25 MB/s. Not too bad, either way. ...That's about a minute per GB... give or take 20 seconds.

For a viable HVX workflow, you wouldn't back up the P2 directly to tape anyway. You would ingest the P2 onto your workstation that has a fault-tolerant storage system itself in the form of RAID 1, 3 or 5. Transfers to tape would be done automatically by the system during off-hours... Nightly backups is not a bad idea.

To shoot that same amount of time to miniDV tape will cost about $668 using $4 tapes. So VXA-2 is about $0.70 per hour cheaper than DV tape in terms of video storage costs.

But again, this is comparing archiving costs to capture costs, so it's not really a meaningful comparison. For capture costs you have ~$70/minute for P2 cards at 720/24pn or roughly $10/minute for a P2 Firestore at the same bandwidth, compared to $4/hour for DV/HDV tape or $4/minute for a DV/HDV Firestore. If you use DTEs to capture then DV/HDV will always be cheaper than the HVX200; if you compare P2 cards to miniDV tape it's almost 18 hours of tape for each minute of P2 capacity. So just one hour's worth of P2 cards at minimum bandwidth would cost as much as 1000+ hours of miniDV tape, which is several years' worth for some of us.

For archiving costs, DV and HDV will be cheaper for any given solution using the same process proposed for footage from the HVX200, hence further off-setting the cost of miniDV tapes. Add it all up and HDV is clearly cheaper both initially and in the long run.

Well, we were discussing long-term storage / archival solutions. So I don't see how you can say my comparison was not really meaningful? Also, your statement above makes absolutely no sense in regards to P2 when properly implemented. In general, people don't re-use DV tapes. They shoot, they capture, they store the tape as their master archive, end of story. With P2 an archive solution is necessary since P2 gets re-used over, and over, and over, and over again... Several years ago, people were whining about all these same issues with film vs. digital cameras. Trying to compare the cost per minute capability of P2 is an exercise in futility. If I use my 2 8GB cards to capture 400 minutes of video over the next 10 days, my cost per minute is about $7/minute... If I do 4000 minutes with these cards, then my cost is $0.7 per minute. So I don't get what you're trying to say... The $70/minute only applies to 8GB cards figured at MSRP and only if we use them once and then use them for the master archive, or simply throw them away.

The best way to look at the HVX and P2 is to consider P2 an extension of the camera - not a media component like DV tape. Increasing your P2 capacity is like increasing the RAM in your computer whereas buying DV tape would be like buying DVD-R discs. If you need more capture time or video workspace in your camera, you increase the RAM with larger P2 cards and sell your old ones...

Consider these two camera configurations and costs:

1 > HVX200, 2x8GB P2 cards, VXA-2 FireWire Tape System - $10,400

2> Canon XLH1 HDV- $9K

100 hours of video archival ability 720pn24 HVX / 24F XLH1:

Config #1 - 12 * VXA-2 tapes @ $22 = $264

Config #2 - 100 * DV tapes (cheap crappy ones) @ $2.75 = $275.

Granted, this doesn't take certain workflow considerations into account, but many of us already have the hardware needed to rotate P2 cards on a shoot (decent notebook PC/Mac or even a desktop system in-studio or whatever). If the HVX200 will work for your projects (managing the P2 workflow is workable or even complementary), then to say it's more expensive to shoot P2 than HDV is questionable. If considering the HVX200 to be a $10K HD camera is not too your tastes or budget, then buy an HD100 and be happy. HD100s are about $4600 now and you can shoot HDV all day long on $1.79 a piece DV tapes you buy at Wal-Mart. And considering these last few numbers, you're right, HDV is a lot cheaper.

Seriously, we can all play with the number so many ways... Either the HVX200 will work for you or it won't. Right tool for the right job, ya know... If my bread and butter was shooting live events, I wouldn't buy an HVX200 as my primary camera (at least not yet).

For archiving costs, DV and HDV will be cheaper for any given solution using the same process proposed for footage from the HVX200, hence further off-setting the cost of miniDV tapes. Add it all up and HDV is clearly cheaper both initially and in the long run.

I have added it up - see above posts and this one as well. If you want a much more detailed accounting showing a few different archival solutions, I can probably put something together over the next few days when I find time. But I can show you situations where DV/HDV actually becomes more expensive. Think large volumes of video. Just as what the numbers start to show in my brief accounting of the VXA-2 tape solution a few posts back and here in this post.

The HVX200 with P2 and DVCPROHD may not work for you and I think you have made it obvious that it won't. But I think you're missing the fact that it will work for a lot of people, hence the high demand and large numbers of pre-orders. I'm not sure what you're trying to accomplish by championing the "cost efficeincies" of HDV vs. P2. Thus far you haven't shown that you really have a true understanding of how P2 works or what it can offer over HDV. The extended features such as the metadata can be priceless if you're transfering footage over to a post-production crew and it can be used for several other purposes ranging from duplicating camera settings, DP notes, database cataloging, etc..

I'm not sure what you're trying to accomplish by championing the "cost efficeincies" of HDV vs. P2.

The whole point of this particular thread was to discuss whether the HVX200 can be operated as cost-effectively as HDV. I've shown why that's not possible in most typical scenarios, and you haven't shown otherwise except in your unique case where you've already paid for some of the required equipment. (So you aren't fully accounting for the total cost.) I've also said repeatedly that I think the HVX200 is a fine camera for people who can make it work for them, and I have no problem with that.

Recapping on the cost issue: once footage is in your editing setup DV and HDV will inherently be cheaper to use and archive because they're lower bandwidth for a given amount of footage, using whatever process you propose to use for DVCProHD storage. So the cost of tape is only an issue at the front end, where it logically needs to get compared to the cost of recording on the HVX200. If you buy three 8 GB P2 cards at $1400 each that's $4200, or enough to buy 1000+ good-quality miniDV tapes. If you buy DTE drives for the HVX200, you can buy more DTE capacity for HDV for the same price. Any way you slice it, it's more expensive to buy and operate an HVX200 than commonly used HDV options.

Thus far you haven't shown that you really have a true understanding of how P2 works or what it can offer over HDV. The extended features such as the metadata can be priceless if you're transfering footage over to a post-production crew and it can be used for several other purposes ranging from duplicating camera settings, DP notes, database cataloging, etc..

Again, that isn't what we're discussing here. I agree that the HVX200 is a good camera with a lot of potential, but cost-wise it simply isn't competitive with HDV. The camera costs more (except compared to the XLH1), the recording memory costs more, and the archiving in your editing setup costs more.

Consider these two camera configurations and costs:

1 > HVX200, 3x8GB P2 cards, P2 Store drive or laptop with external hard drive, VXA-2 FireWire Tape System - $___

2> Sony Z1U, 1000 miniDV tapes, VXA-2 FireWire Tape System - $___

Those are realistic setups for anything involving more than a few minutes of shooting time out in the field. But then most people won't buy 1000 tapes up front, so option 2 is clearly cheaper initially -- enough so to allow for buying a second HDV camera if necessary.

Not that it really matters, but my intension for starting this thread was just to engender a general discussion on this subject. Eventually, comparison to HDV have to come up as that's the big competitor. If you ever saw the the DVD Panasonic put out to promote the HVX, you'd see how much of a point they made in comparing their product to HDV options.
Kevin, I'm still a little uncertain about your numbers though. I get about $1000 for 100 hours of 720p24 (250 gig HD ~ $100 x 10 = $1000). There's always shipping, etc. There also the cost of the TrayDock at $175. The real bummer is if you backed up everything in case of hard drive failure, which would mean another $1000.
When you say "full-bandwidth DVCProHD" do you mean 720p60? Once you throw that in it gets really hard to make any comparisons as HDV can't do variable frame rates. I know you don't care for the comparison to begin with though. Now, I love slow motion, but wouldn't you think a figure that counted in around 10% slow motion would be a little more helpful here? Also, what about overcranking? Honestly, I'm asking b/c I don't know, but if I understand correctly, that would work like overcranking but in reverse so you'd actually save hard drive space. Again, not sure about this though. Anyway you count it though, I'm sure you're right and that HDV is a cheaper route.
I actually like this discussion. Some ways to look at things and options that I did not know about.

I'm still a little uncertain about your numbers though. I get about $1000 for 100 hours of 720p24 (250 gig HD ~ $100 x 10 = $1000). There's always shipping, etc. There also the cost of the TrayDock at $175. The real bummer is if you backed up everything in case of hard drive failure, which would mean another $1000.

720p24n is 40 Mbps or 5 MB/sec or 18 GB/hour, so a 250 GB hard drive formatted to ~245 GB would give you 13.6 hours of storage. Shoot 720p30n and that drops to under 11 hours. Shoot 720p60 or 1080p30 and it drops to 5.4 hours per drive, and you would need a duplicate if you wanted to ensure the security of that data. That's as much as $40 to archive one hour of HVX200 footage with a secure backup, compared to about $10 per hour to archive DV or HDV footage using the same approach. But taking the lower case of using 720p24n it works out to about $14/hour of footage compared to $10/hour for DV/HDV, and that cost difference would pay for an hour's worth of miniDV tape.

So the best case scenario is that it costs the same to shoot 720p24n and make two archival copies as it does to shoot DV/HDV with two archival copies plus the original master tape backup. I suppose that's not bad, but it's leaping through a lot of hoops to make the HVX200 look cost-effective.

Absolutely the ability of the HVX200 to do different frame rates is an impressive feature, and when you start talking about that then cost may not be the most important consideration. That's why I said earlier it doesn't really make sense for now to compare the HVX200 to HDV; better to compare it to the cost of other solutions for shooting DVCProHD. When the HVX200A is selling for under $5K and I can buy 32 GB P2 cards for, say, $250 each, then we can discuss that being a cost-effective alternative to HDV. That's at least 3-5 years away based on current trends.
