Are you on an AMD GPU?

Hi.

I'm on an Nvidia RTX ADA Generation version 551.79

I'd try build 208 or enabling legacy AVC in 315 may help. Note that 208 can't open projects made in 300+.

Can you show me where to download build 208?

@Marc-Gold please see the link in the 1st comment.

Thanks for your help. I installed VP21 build 208 and re-rendered my video once again with perfect results. Does anyone know if this (sync) is a known issue in build 315, and if it's being addressed?

Not without having:

• Mediainfo report of your source media
• a sample of your media
• your File I/O settings

There are many media decoding issues with 315 but please provide the info John requests (and even better a short sample of the problem footage) so others can test it and we can ask for this type of media to be made compatible going forward.

This is the error message that I get when I try to upload a small video file. Don't know how to get this file for you.

@Marc-Gold It tells you the supported formats!

MP4, MOV, WMV, AVI, MPG, FLV, MTS

You're trying to upload an MXF file which is not on that list.

If you want it displayed as video on this site, you'll need to use one of the supported formats. If you're trying to share the MXF file for others to look at, you need to upload it to a third party site (like google drive, drop box, a personal website, etc...) and provide a link to download that file. It sounds like you need the latter - upload it to a website and then provide the link to the file here.

Hi Marc, I think you are having some issues with the forum here.

For MediaInfo you can just copy and paste in the text it gives you without replying to another comment.

For the MXF file please share a link to it on a hosting service like Google Drive or Dropbox or Box, etc. If you have difficulty doing this please message me and I can help.

Is this helpful?

You're close. Try view/text and then highlight (control + a) everything and paste it here as plain text.

Hi all, Marc was kind enough to upload files for testing and I was able to replicate a sync issue with MagixAVC (Mainconcept).

Here's a file you can download for testing.

Using my laptop I just put it on the timeline and rendered to a MagixAVC template (NVENC then Mainconcept). I brought them back onto the timeline and the Mainconcept one's audio waveform is clearly not aligned.

Mainconcept HEVC and AVC match each other but not the other renders.

HEVC QSV matches the original but not HEVC Mainconcept.

Do others see this?

Do you see it with VCE as well?

@RogerS I downloaded the clip. How can you tell if there is a rendered sync issue?

Rendering with HEVC Mainconcept "looks" the same as with VCE.

MXF / PCM / AES causes known sync issues with some Vegas versions and decoders.

Note that the mode is frame based, adopting the video properties, but it does not appear to be interleaved.

The bug has popped up in various forms for years. I tested it about a decade ago (VP14) when I was still working.

Rewrapping to MP4 in Shutter Encoder should solve this straight away.

I downloaded the clip. How can you tell if there is a rendered sync issue?

Rendering with HEVC Mainconcept "looks" the same as with VCE.

@Reyfox I can tell reimporting the clips into VEGAS that the audio is not aligned between Mainconcept and NVENC and the original by playing them back at the same time and looking at the waveform.
I can't tell what the sync should be (which one is right) given the nature of the clip and asked the OP for a file where we could have a clear view of someone speaking or singing.

Thanks for the perspective, Mark-y and workaround. I'd like VP 21.315/ VP 22 with Mxcompound to be able to handle this directly so hopefully we can help get to the bottom of the issue.

I've found that if I render just a minute or two of a video clip, that short, rendered clip will show perfect sync, but if I render the whole clip (1 hour long) the part that showed good sync in the short, rendered clip will be out of sync. It seems like the length of the clip being rendered has something to do with the sync issue. Would you like me to put the whole hour-long clip in your dropbox?
