Best Render for 720p & Bluray render question

[John Rofrano]

[Shoestring Videos] “I am not so sure about using the Sony codecs included in vegas. Is there codec that would be better?”

It depends on what version of Vegas Pro you have. If you have version 11.0 use the MainConcept AVC codec. if it’s version 10.0 or earlier, use the Sony AVC codec. Both should have an “Internet 720p” template that will give you the MP4 file that you want.

[Shoestring Videos] “2nd question. Can you create Bluray onto a DVD9 that will play and be recognized in Bluray players. same scenario, 74m 1280×720 and I figured I would use the avchd codec at about 8mbps.”

Not reliably. Blu-ray video on DVD media is not an “official” part of the spec so Blu-ray playes do not have to support it. My Samsung Blu-ray player cannot play those discs reliably. They stutter and eventually stop playing. So unless you want to hear a lot of complaints from people, spend a buck and buy Blu-ray media to make Blu-ray discs. Using DVD’s just doesn’t make any sense in 2012 when Blu-ray media can be had for $1USD.

In fact, some Blu-ray players will reject “Blu-ray on DVD” without even trying. Of course, some won’t play BD-Rs, either. Like DVD before it, the Blu-ray people didn’t really consider the small producer when defining the requirements.

If you can’t do BD-R, your best best is AVCHD on DVD. Curiously, while there’s almost no difference between Blu-ray on DVD and AVCHD (which was derived from Blu-ray) on DVD, data-wise or structurally, you’ll find that nearly every BD player supports AVCHD DVDs. The reason is simple: it’s a camcorder format.

DVD Architect can’t make AVCHD discs, but there’s a freeware tool, multiAVCHD, that can. There are more restrictions than on Blu-ray. AVCHD only supports AVC video and AC-3 audio. You have to encode the video at 18Mb/s or less… that’s actually also true for a Blu-ray on DVD to have any chance at working without stuttering, either, simply because Blu-ray players are only expected to have a 2x drive in DVD mode… that 18Mb/s is roughly twice the ~9Mb/s you get for DVD video. There’s no guarantee, but this will be more compatible with BD players than any format other than Blu-ray.
