HD video on DVD DL disc

hnguyen wrote on 11/2/2012, 12:13 PM
When I render my project to DVD, the video & audio are in sync. When I render the same project to AVC or BlueRay format then the video & audio are badly out of sync. Since the project is 6G, I am burning it to a DVD DL instead of a Blurray disc. Is it because the disc is not blueray disc? For the Blueray render I kept the data rate as default.

Many thanks for any advices

Are you getting out of sync playback on a BluRay disc player?

The files are identical, whether you burn them to a DVD or BluRay disc, so that can't be the issue.

But, if you're playing the disc on your computer, it could be that your computer isn't capable of processing the hi-def video off the disc fast enough and you're seeing a lag between audio and video.

Yes, I'm getting out of sync on a Sony blueray disc player. One more thing, my burner is not a BlueRay burner, it's a DVD burner and BlueRay player. Maybe that's the reason.

Thanks

No, that should be just fine. What is more likely is that you have exceeded the total bitrate that a DVD disc is capable of delivering to your player, i.e. you have encoded video with a bitrate in excess of 15,000Kbps, or exceeded the total bitrate allowable with video plus audio (don't recall what that is OTTOMH).

I took the following from Wikipedia:

QUOTE
DVD-Video discs have a raw bitrate of 11.08 Mbit/s, with a 1.0 Mbit/s overhead, leaving a payload bitrate of 10.08 Mbit/s. Of this, up to 3.36 Mbit/s can be used for subtitles and a maximum of 9.80 Mbit/s can be split amongst audio and video. In the case of multiple angles the data is stored interleaved, and so there's a bitrate penalty leading to a max bitrate of 8 Mbit/s per angle to compensate for additional seek time. This limit is not cumulative, so each additional angle can still have up to 8 Mbit/s of bitrate available.

Professionally encoded videos average a bitrate of 4-5 Mbit/s with a maximum of 7–8 Mbit/s in high-action scenes.
UNQUOTE

For DVDs I personally use 6 Mbit/s 2-pass VBR for video which is more than adequate for a good picture quality and AC3 at 192 Kbit/s. Going much over 8 Mbit/s for video may choke your player.

Thanks everyone for the inputs. I managed to get the project to fit on a 4.7 DVD with a 5M bit rate and it works fine.

Since you're playing the DVD with HD content on a Blu-ray player, the same data rate limitation that existed for a hardware DVD player does not necessarily apply. The decoders in the Blu-ray player are capable of much higher bit rates than DVD and the motors can spin the shiney media a little faster. I have routinely put HD content in the form of Blu-ray images on to DVD media at 15 mbps or less and it worked on my hardware. Trust me, it doesn't work on all Blu-ray players. Since you are doing something that is a non-standard use, no manufacturer promises you anything.

But, you can still do it.

I should think mileage also varies by the brand of disc & burner -- the folks over at myce.com have accumulated quite a bit of data showing neither blanks nor burners are all created equal.

Brand of disc and burner and their current state of health could affect reliability, (reluctance to play, dropouts, etc.), but if a BD player does not support playing HD video on red-ray DVD then there are no ifs and buts about it. It will never work.

For me, my BD player (actually recorder) claims to support AVCHD discs but it refuses to play BD content on DVD as produced by DVD Architect (before SCS removed the feature!), unless the ISO file is first patched by a third party utility. However, such discs apparently play on some other people's BD players without the need for patching. Also, my player will play AVCHD discs as produced by some other software such as MultiAVCHD, PowerDirector, etc.

AFAICT a majority of BD players WILL play BD-on-DVD altho it seems to me my LG BH200 needs an older version of firmware to do so. Here's a discussion of this subject that I found--bottom line being that "ability to play" is hit-and-miss.

BluRay burners start at $50, occasionally less.
Why even bother trying to put a few minutes on a DVD??

Yes, A BD burner is at the top of my Black Friday shoping list 8-))

Just FWIW...

Blu-Ray on DVD is part of the Blu-Ray spec, I *think* stuck in there by one of the distributers in case Blu-Ray pricing never came down. Stand-alone players AFAIK tend to treat BD 5&9 discs as AVCHD, & some do the same thing for burned rather than mass-produced Blu-Ray discs. Some Blu-Ray players will handle most anything you throw at it, while others can be very picky -- research before you buy. Same can be said for BD burners -- quality & performance varies by make/model. Note that if/when buying a BD burner, if you want to burn or play BD in XP it can be worth it to buy a burner that comes with software, e.g. the PowerDVD that came with my first BD burner worked to add the format to XP's capabilities where nothing else, including the common hacked drivers did.

BD 5&9 *possibly* means discs that'll last longer than cheap BD blanks -- Google & you'll find reports of unreadable discs a couple few months after burning, plus many [most?] cheap discs have a flexible film protection layer rather than the hard plastic a DVD uses. BD 5&9 means lower costs -- the difference between a $15-$20 DVD burner & ~$50-$60 BD burner matters to some people... there's not a huge price difference between DVD 9 & BD 25, but with 100 Verbatum DVD 5 blanks for ~$18, for some the savings are worth it. BD 5&9 also play on PCs/laptops without Blu-Ray drives, so it can work when you've got a number of PCs you want to view Blu-Ray content on but can't justify the cost of upgrading each one. I've had decent luck updating old DVDs, re-using the video but updating everything else including the subs so it looks better using Blu-Ray players, though that's really a niche thing, & in that case it doesn't make much difference [if the players can handle it] using DVD or BD blanks.

720p & 1440 x 1080 seem to work well enough on BD 5 &/or BD 9 -- the quality difference between BD 9 & BD 25 *IMHO* seems about the same as SVCD vs. DVD, assuming both are done equally well, but you'll find opinions that run the gamut between trash & identical. The latest version of DVDA stopped listing BD 5&9, but that's not tragic -- encode your audio/video to fit a DVD 5 or 9 in VP [or using whatever], create the DVDA ISO, mount & optionally copy the contents elsewhere, test, burn with Imgburn.

Thank you very much for the tip. Mikkie. I will do my homework
