The reason AVCHD isn't used, is obvious: 16/17Mbps AVCHD delivers no better quality than does an HDV. It delivers less quality than my JVC does at 30Mbps. Only IF 24Mbps AVCHD and AVCCAM prove themselves -- will AVCHD be better than HDV as an acquisition format. Since, by definition, a format OTHER than AVCHD are being used by MOST shooters in the world -- it is "irrelevant." AVCHD to AVCHD is simply not going to be used by other than consumers -- and since the reliability of Smart Encoding is suspect and Nero offers limited editing -- I doubt it will be used by even the majority of consumers. Moreover, the concept of AVCHD to AVCHD cannot apply to those that edit with OS X applications -- which are the only apps (other EDIUS and Media Composer on the PC) that I'm interested in. Frankly, I wouldn't use any PC application for VIDEO editing except these two. Nothing would make me use the consumer programs. And, I wouldn't use Vegas either -- although there are many who LOVE Vegas. All the talk about recompression loss misses the fact that EVERY HD production starts with one codec and ends with a different codec. All the talk about loss of time and quality are irrelevant. That's HOW IT'S DONE. The key, of course, is the use of a near lossless codec as an intermediate. Anyone who's made a film knows there is a negative, an INTER-negative, and a print. And, of course, the print is of lower quality. The loss is simply part of the deal. I really think talking about doing it a "different" way is just a waste of time. The world isn't going to change HOW it produces video based upon an arguement against how its done. HOWEVER, as a DISTRIBUTION format for those without a BD burner -- AVCHD has a real role. AS LONG AS ONE USES THE RIGHT ENCODER. In fact, if the Sony AVC codec is used at 16Mbps, there's no meaningful visual difference between an AVCHD disc and a BD disc burned with 25Mbs MPEG-2. In other words, given the zero price for a DVD burner and the $1 cost of a DVD -- the quality difference is fully acceptable given how cheap the AVCHD solution is. The BD should look a LOT better given $20 per disc! This makes perfect sense for two reasons: 1) AVC is about 2X better than MPEG-2 2) Encoding for a distribution only requires AVCHD be encoded and played back. This is the same as when one shoots AVCHD: Encoding then playback. PS 1: I need to remind you again that BD-5/BD-9 ARE standardized formats. All BD players that meet BD specs -- which leaves out software players who seem to need to meet no standards -- can play these discs. The ONLY thing that prevents this THIRD path is that, unless you buy Sony DVD Arch. -- you can't dial AVC up above 16Mbps. As soon as one finds a high quality AVC codec that can be set to 35Mbps -- then BD-5/BD-9 will offer better quality than MPEG-2 BD discs. Of course -- only for very short movies. :) PS 2: as prices drop for BD Burners -- AVCHD will be less relevant as a distribution codec. And, when Sony replaces HDV with something like XDCAM EX -- that is where the prosumer market will go because it is far easier to edit.

I mix "everything" in FCP, FCE, and iMovie 08 ($85). And, of course, you can do so in EDIUS. Then, you need to follow the correct workflow to burn a disc.

Earlier I said there were 3 features, but no more than 2 can be put on a AVCHD disk at the same time. 1.) 24p 2.) AC3 5.1 3.) menus So far no one has managed the 1st because even the native AVCHD cams that shoot 24fps add pulldown. The TSMuxer 1.8.4b workflow is the only one that accomplishes 24p on red laser. To appreciate that, the HDTV monitor must support a 72hz mode. This eliminates the judder frame. But Steve is right about intermediate formats being virtually lossless. The only editing less lossy is uncompressed or native, the latter is what you or I would try to do. The intermediate formats are what Steve would use because he color corrects. |

I would also point out that while DVD Architect 5.0 allows you to burn BD5/9, the disk only plays back as a data disk. In other words, you have to navigate the disk to the STREAMS folder containing the video file. That's just useless! |

I think we may have to consider 1080p30. That gets rid of pulldown and keeps the frame rate low. PS: I get a newsletter from Japan. A story on a new 3D camera has this sentence -- I kid you not. "Some of the visitors said the female product presenters in the video were appealing and impressive in particular."

I have been using hard disk backup rather than optical disk since the cost per gigabyte, the speed, and the longevity seem to all favor it. My experience using optical media, specifically DVD media, has been quite poor. A significant percentage of DVDs I authored when this media first arrived are now unreadable much less than a decade later. I assume the dyes have improved a lot, but I still avoid using burned DVDs for anything really important. Regarding AVCHD workflow, I like it fast and simple, so I am going to argue on the side of simple programs despite owning and using all the other ones as well. Nero is far from being my best software, and it clearly cannot do all the things some folks want to do. You might want to take a look at Cyberlink PowerDirector 7 Ultra. Not until just a couple weeks ago did they finally fix several huge bugs and finally implement smart rendering of AVCHD. Its editor is more traditional and robust than Nero's, its user interface is also more 'standard' than Nero's, and the smart rendered output quality is indistinguishable from the original AVCHD footage. The free trial will let you make your own judgement. Its motion menus, titling, filters, other special effects are quite complete. Why not give it a shot and see what you think. Larry |

Steve,
No doubt my preferences and beliefs come from the consumer AVCHD vantage point, and yours come from the professional perspective. The resulting disagreements are, as before, mostly a matter of philosophy. And I truly think of AVCHD as being a mass market, low cost, simple, and essentially non-professional world, whereas your workflows are geared to the opposite extreme. To me, Final Cut Pro, Canopus, Avid, and all the other heavy duty tools, in this instance, are "irrelevant" so I guess I can borrow the use of your term in this regard. The 'gray' area where the 'prosumer' lives is, no doubt, the territory where our philosophys tend to clash. I am very hopeful that Adobe, Sony, and others will begin to fill the void properly, since the present tools barely serve this market adequately in my view. Hence we are all struggling to find ways to make disks which can combine the various features prosumers are asking for, using Nero fly swatters and Final Cut sledge hammers in a most comical way to get to a final result.

If this is a truly "standard" format which is written into the BluRay spec, and yet even Sony does not support it in the PS3, the de-facto BluRay player now serving probably 90% of the BluRay market, then what possible reason would anybody have to use it? I really have to wonder where Sony is coming from with this whole matter of AVCHD support. Since Vegas and DVDA professional products don't even support it, let alone their cheap home versions, they have once again left their camcorder customers with excellent acquisition tools but absolutely no easy delivery method. I understand their financial motive to keep BluRay burners and BluRay media flying off the dealer shelves. And I have lived through the nearly 5 year HDV product cycle and STILL DO NOT see a low cost delivery method. What a joke...... I would imagine that merely deleting the CERTIFICATES folder from the disk which Sony makes from Vegas/DVDA may be enough to allow my software players and possibly the PS3 to play the disk. Of course Sony choses to hide the CERTIFICATE and BDMV folder when the authoring is being done and deletes it immediately when burning is complete, so the only way to make a playable disk would be to rip, edit, and re-burn the disk without the CERTIFICATE folder. Hardly worth the effort given no menus, re-rendered video, and hours of wasted time. I will note, with some concern, that the latest Corel Movie Factory 7 Pro no longer offers an explicit AVCHD option like the MF^+ version does for the project, although it will author red laser disks when AVCHD format is selected at burning time. I need to start using it to see if Corel has somehow watered-down the AVCHD feature set for reasons related to my comments above. This would not be the first time that Movie Factory has had features removed to satisfy the lawyers from the BluRay world. A couple years ago MovieFactory offered red laser authoring for BDMV and it was quietly removed........ Larry |

I could not resist the temptation to see if removing the CERTIFICATES folder from the Sony-produced red laser disks from Vegas and DVD Architect 5 would then allow them to play on the PS3.
By first burning the Sony Vegas and DVDA disks, then ripping them, and then burning them again without the CERTIFICATES folder, I learned that they are still considered "Data Disks" just as they were originally. The only way to play them is to navigate to the STREAMS folder and then play the single .m2ts file. Obviously this is of no value whatsoever, since the original non-authored clip could be played directly on the PS3 without creating this peculiar red laser disk and going through the additional steps. There apparently is some other file change within the BDMV folder which the Playstation uses to determine eligibility for playback. It remains unanswered WTF Sony is thinking by doing this.........

If you would only try the TSMuxer1.8.4b workflow, you'd be surprised how painless and fast a functional BD-5/9 is. You won't have seen HDV quality this good since you had them on HD DVD. All it lacks is menus.

Tom,
I can bring the demuxed .evo video over with no problems. I am still looking for a way to get my original demuxed audio (which is in .mpa file format) into digital dolby. I have Besweet and some other tools here, but going from mpa requires another conversion and I have yet to find a simple converter. Larry |

I found thread on this topic -- maybe. BD discs have a bit that signal copyrighted material -- not ACCS. The PS-3 looks at this bit and if it's set and the disc isn't a BD-ROM, it refuses to play it because it thinks it is a illegal COPY. Some say this only applies to BD-RE. The key is that the encoder shouldn't automatically set this bit. Supposedly there is a Java program that turns the bit OFF. Other folks claim there is another bit that is set.

Maybe TSMuxer will accept the .mpa as is. I think it should accept a AC3 stereo .mpa. Have you tried that? It's not totally necessary to feed it elementary streams anyway. It won't accept muxed .m2t transport streams, but will accept a muxed .mpg program stream. Besweet was a frustrating waste of time for me, but I digress. You should try feeding TSMuxer some various muxed files, .m2ts, .mpg. Some .mpg files could even have multiple audio streams embedded. TSMuxer will split them, and you put a mark in the checkbox next to the ones you want to keep. You can do more than just BD-5/9 authoring with it, it's a useful conversion utility as well. |

Duuuhhh!! Forgot that Vegas did exactly that. The mpa to ac3 was quick and simple, and the remuxing went very quickly also producing a totally functional BDMV and Certificate folder which do indeed play beautifully. The only difference in my workflow is that I begin with streams from the HD DVDs, stored as .evo files, and first demux them with EVODemux. It would be really nice if somebody made a standalone app which inputs an HD DVD and outputs a BDMV and Certificate. Certainly I am not the only one with a big HD DVD colection to convert. These are all home made and thus have no DRM issues. Thanks for the help Tom. It was / is a great suggestion / recommendation !!!! Larry |
