Pro 15 won't play YUY2 files, but plays UYVY

problem: does Pro 15 (build 177) not play YUY2 .AVI files? plays audio but not video in the Timeline. I understand AVI is a container and Vegas can't play every type of file but it does play UYVY. Don't both codecs have the same 4:2:2 color space? MediaInfo format reports UYVY as RGB and YUY2 as YUV.

boring back story: New to Pro 15, had 12 for years. Recently started capturing NTSC VHS via VirtualDub because I have the option to select YUY2 vs. UYVY. I guess AVISynth prefers YUY2 vs. UYVY and by capturing YUY2 I save an extra conversion process. I'm deinterlacing & upscaling in AVISynth & doing all other editing in Vegas. The rendered AVISynth-file plays fine in Vegas, is this because it's a RGB file? or is there something missing that I can't play YUV?

It's not the end of the world that I can't play the raw YUY2 in Vegas before conversion, but it would be neat.

I do have another somewhat related question; When I render x264fw-H.264/MPEG-4 AVC, the files ends up an .AVI. I assumed it would be an .AVC?

Thanks in advance for any suggestions.

Can you tell me what the difference is between I-frames 15 & 12? Before I read your response from that link I rendered using 1440x1080-24p (which has an I-frames of 12). Just curious how that affects my 59.94 render.

The templates are starting points. Given the characteristics that are available to change manually, you can create many different outcomes from different starting points. Different encoders expose different items that can be changed.

I rendered 1280x720-59.94p video with the Mainconcept MPEG-2 Blu-ray template using all of the I-frame options offered and all rendered fine. All passed through DVD Architect without re-encoding.

If you have the processing power and want to have equivalent picture quality at lower bit rates, Consider using a customized Sony AVC Blu-ray template.

Thanks for doing all of those tests with the various I-frames options. I was hoping the combination of using the correct I-frame for a 59.94 project, and updating my BD burner firmware would be the solution as to why all of a sudden no new burnt BD's will play in my older set-top player.

I think I have the processing power to use AVC (see stats below).

I’m still confused about rendering in Vegas & DVD-A.

My project is 1hr 31min and delivery media is BD-25. In
DVD-A, disc space used is 19.3gb which reports 78% of 25gb, actual size of
burnt disc is 13.7gb. Yet I’m still getting warning messages of “the video X .mv2 will be recompressed” “the video {and
audio} X.m2t will be recompressed” (I
made a short 15 second intro and did not render the video & audio separately
that’s why it’s .m2t vs .mv2). I’m surprised the 0.98gb 16b/48k PCM audio from
the main project didn’t get recompressed.

Vegas settings:

-Project Properties: HD 720-60P (1280x720 59.94fps).

-Render-as
template: MainConcept-MPEG-2 blu-ray 1440x1080-60i, 25Mbps.

[customize template]

W:1280 H:720

field order: none

-[√] Prioritize quality over speed Video quality: High 31

-Variable bit rate [√] Two pass Max=45,200,000bps Avg=33,750,000bps Min=13,500,000bps

-[√] Save as separate elementary streams

-Sony Wave64 48k 16b PCM

Estimated file size: 15gb

I used an online bit rate calculator to get the Max/Avg/Min
rates based on overall minutes, audio bit rate, blank media size etc.

DVD-A settings:

-MPEG-2 1280x720 59.94p, 16:9

-Bit rate: 25.9mbps

25.9mbps was the highest I could go before error messages. I’ve
read 90 minutes is about the max you can have for max quality on a BD-25.

Even with all of these re-compress warnings, why is only 78%
of 25gb used? You can definitely see about an inch of unused space on the disc.

Your max bitrate is WAY TOO HIGH, your average bitrate is WAY TOO HIGH. Your max should not be over 30 or 35 at most. Average should be close to your target (25). Min is okay.

You should always render audio separate from video, it just works better that way and since you want either PCM WAV (I never used Sony wav for DVDs or Blurays) or AC3, this is the only way to achieve that for audio. You don't want to use the audio that is rendered with the template. Just turn it off because sometimes DVDA will import this audio and if you don't change it, it may not be compatible.

It is all about math as far as how much is used. If you do the math of 25mbps at 90 minutes x 60 seconds, you can estimate the disk size and it probably won't fill the disk.

"The current practical maximum speed for Blu-ray Discs is about 12× (54 MB/s)." I've read that the brick wall hardware maximum bit rate for all streams is enforced by a 50 Mbps hardware limit. Subtract all audio and overhead bit rate from 50 Mbps and your "-Variable bit rate [√] Two pass Max=45,200,000bps" is pushing it, as David says. I once had a 13 title Blu-ray that would fail to create an ISO in DVDA on title 12. It never went to completion until I lowered the maximum bit rate in my Mainconcept render template to 39 Mbps for title 12. Aside from using a bit rate calculator, you could also benefit from a tool to look at rendered bit rates. Here is one that many people here have used to looky-lou rendered files.
