SVP 11 – Rendered Sony AVC/MP4 file – audio seems to sit just slightly behind video?
Just output my first render on my new PC with SVP 11 and found a problem…
https://youtu.be/11g_iWzsAkM?hd=1&t=4m44s
The white flash should sync perfectly with the beat of the music kicking in.
It does on the timeline in Vegas, and when I preview inside Vegas but the MP4 file it outputs is identical to the YouTube upload, the video runs a fraction of a second earlier than the audio.
Is this a known fault and is there an offset I can enter or will I just have to manually nudge my audio tracks under SVP11 compared to 8 ?
Thanks folks 🙂

i got over a minute into this video and didnt see any white flashs…maybe im just blind.
But to answer your questions I havent experienced what your talking about.

Hi there,
4.40 would be an example – I did put the link in the YouTube URL but this forum software stripped it out – doh!

i didnt see a white flash at 4:40 so i guess you meant 4:46
try rendering to mpeg2 or xdcam and see if the problem repeats.
also you didnt mention what output setting you used but again i had to assume you used mainconcept avc mp4

Re: SVP 11 – Rendered Sony AVC/MP4 file
Its all in the title 😉
I’ll give another encoder a shot later, dont really want to use something else as Mainconcept is dog shit, especially with GPU rendering enabled it looks like crap.
Will give it all a go later tho. In the meantime a workaround (dont we love Vegas and its work arounds) is to make project, grab audio and move it backwards 2 frames

you could also take the outputed mp4 back into SVP and see if the audio peaks synch properly with the rendered video (as compared to the project audio peaks)

It seems to be out a touch too.
What I found last night was the sync on YouTube drifts out more and more depending on how long the video is :S

Thats at 12 minutes.
EDIT: add the ?hd=1&t=12m6s to end of link
