Right… I clearly was already aware that the output was YUV, however VP6, Sorensen(sp?), or whatever codec is used isn’t the issue. FLV is a container, not a codec, the issue is how do I make it encode what it says it’s encoding? I’m assuming that if the only possible output was YUV then the encoder would say YUV + Alpha, however it quite specifically says RGB + Alpha, so I’m guessing there must be another codec available that I don’t have or something.

When I export to Uncompressed AVI and select RGB + Alpha, it outputs RGBA as expected. I also have the the Color Management output profile set to sRGB, which seems to do nothing. I don’t understand what the point of even having the option to choose an output format is if just ignores your choice and does what it wants…

I do this but it exports as yuv + alpha, not RGB, do you know how I might export to rgba?

You sure can, in fact you should be able to export from VMS directly to a Bluray image file and bypass DVDA, (tools -> burn disc -> bluray) . You really don’t need to use both of those applications and would probably save time by cutting one of them out of the equation… As far as the second render is concerned are you sure it’s actually re-rendering the video and not just muxing it / splitting it into chapters? What is the size variance between the original avc encoded / m2ts file you are trying to reuse and the total size of the bluray image?

(Don’t listen to negative Nancies, anyone who tells you something can’t be done is probably just too lazy or too stupid to figure it out themselves. The guy looks like he just left a Bon Jovi concert for crying out loud, I wouldn’t be surprised to find out he doesn’t actually know what he’s talking about because he still hasn’t upgraded from VHS.)

I’m seriously impressed with the quantity and quality of actual real information you have been providing. I simply wanted to express my gratitude, it seems like 90% of people in forums these days answer questions despite the fact that they know absolutely nothing about the topic.

I just wanted to chip in too that I’ve been periodically searching for a means to encode real MVC video streams and have noticed that there are a lot of companies taking advantage of people by claiming to support MVC encoding but none of them actually work.

Some examples:

Cyberlink Power Director claims it will export to “MVC” but what you end up getting is an m2ts file with two almost identically sized AVC High@4.1 streams, once of which has had it’s headers altered to include the word Stereo and a multiview count.

The Haali Media Splitter / CoreAVC / Mainconcept gang does pretty much the same thing.

Sony Vegas seems to be the closest to actually getting it right, and will actually export a single stream m2ts that handles the compositing of the secondary view properly and combines both views into one stream in such a way that if you demux an ssif file and use the result to create your video the end result will look identical without glasses on. The only problem is that either their headers are incomplete or there is some other info missing so the resulting video isn’t recognized as multiview…

Do you know what the actual 3D Bluray discs themselves mastered with? All I want to be able to do is take a series of ssif files, strip out the 18 audio streams and all the subtitles that I’ll never use and merge the result into 1 m2ts / mp4 / mkv / etc… file in such a way my TV will play it (it actually plays ssif files if you rename them to m2ts but can’t handle the bitrate over usb so they skip)

Basically I’m just looking to create my own version of something like this, which as of this moment has not been possible using anything currently available, I haven’t even been able to find anything that will demux/remux Stereo High:
