V1U-Mac User Temporary work around

[Daniel Boswell]

Just spoke with Brad Wright and he said his product does allow you to import 24p from the V1U. http://www.dvdxdv.com/HDVxDVsite/download.html

Just tested it and indeed it works:

Of course it will import this file. This file is a standard 1080i60 HDV MPEG file.

This is simply a case of editing 24p information on a 60i timeline... A major benefit touted by Sony for their method of storing 24p in a 60i data stream. This is not a new idea and is not magic. Many Sony cameras do this and have done so for years. This is also how 24p information is transmitted over 1080i60 HD SDI.

I'll quote item 4 from the the Sony webpage here under the heading: 1080/24p acquisition with 2-3 pull-down recording - Compatible with existing Sony professional HDV equipment

4. A 60i HDV file (2:3 added back in), for creating an HDV edit master


THIS IS NOT A NEW IDEA, but one that has been used for many many years, and is still used today and every day for all telecine transfer to video, and 24p transfer to 60i in broadcast facilities the world over. Telecine was first used in the 1950s when video tape was first used in broadcast studios. Telecine is a method used to transfer film to video tape.


====== Suggestion to DSE ======
I think it would be helpful if one of the experienced moderators here (DSE hint hint) would create a sticky thread FAQ for 24p over 60i including a little history about telecine in broadcast, 24p DVD, and 2:3 pull-down in general.

It would also be helpful if some of the more common misunderstandings could be cleared up in this same FAQ. For instance, explaining to newcomers that 1440 x 1080 is really TRUE HD. Newcomers tend to compare numbers without having a background, about how things are done, or how they work.

For instance, I would suspect that without any background, a typical newcomer may fall into the trap that on paper the new Sony HDR-SR1 is, on paper, a better camera than the PDW F900. The reason for this conclusion would be because the Sony PDW F900 isn't a TRUE HD camera because it's resolution is only 1440 x 1080.

While this may be a logical conclusion to a newcomer, all of us know that nothing could be further from the truth.

There was much confusion in the DVX-100 community over this too. And many are confused about 24F vs true progressive in the Canon area.

If such an FAQ were created it would be very helpful to many, even experienced users on this board.

Thanks, Dave.

Than why doesn't FCP currently support it?

Actually that's not a bad idea at all. It's been a goal of ours to (eventually) maintain a FAQ per forum around here. The topic you suggest is a good one. I would put it at about equal priority with a FAQ describing the various causes of fringing in HDV images, especially the primary culprit, known as the chroma subsampling issue. Unfortunately there is much confusion in this area as well, since many newcomers tend to quickly and quite erroneously attribute fringing to "chromatic abberation." So yes, there is obviously a lot of education that needs to happen here in a wide variety of technical topics that are highly relevant to this community. Sometimes it seems like an uphill battle in getting certain minds to open up and discard their mistaken pre-conceived notions, but thanks to the many talented and knowledgeable folks we tend to attract, it becomes an eventual win-win situation for all who find this site. Hope this helps,

Because it doesn't remove or add pulldown from/to HDV.

EDIUS 4 has a "24p over 60i" setting that removes the pulldown on capture as HDV is converted to their HQ codec.

Only Vegas supports 24p as native HDV.

Supposedly Apple was to have an upgrade ready for the V1 when it shipped. Maybe at MacWorld.

More confusion coming in 2007 as "Full HD" camcorders are coming that "capture" and "record" 1920x1080.

That's one of the points behind the V1's 3ClearVid system. It can output either 1920x1080 or 1440x1080. The next version of AVCHD will record 1920x1080 at 24Mbps. Even 1080/24p will be supported. This format will likely replace HDV when the second generation AVCHD codecs arrive as PQ is still not equal to HDV.

JVC will also release a consumer "Full HD" camcorder that records to HDD.

These consumer camcorders "Full HD" are designed to match "Full HD" displays.
