Can't open mp4 files in Vegas after rendering out from Vegas
on Jan 30, 2018 at 12:34:45 pm

Hi!

I'm using Vegas pro 14 to frameserve my projects to avisynth, do qtgmc deinterlacing, etc and then render x264 through megui. Now when trying to open a finished file again in Vegas, it hangs. The final product is a mp4 avc file with 50 fps 720p, nothing special. Opens up in media players, plays back fine. Why it should hang in Vegas? When it tries to open it actually reads the peaks for the audio and the file appreas on timeline, but the cpu is running like anything and the program can't read not one frame. Why is it like that, any ideas?

Could you offer a sample file for download?

I think I figured out the answer, or half of it. I made the sample and it opened up fine, although a long video with the same settings is too heavy to handle. I then started to scrutinize on settings and found out that the files which are rendered with x264 settings of High avc profile and Level 4.1 open up fine, whereas when the level is set to 4.2, they hang. I can just render with 4.1, no difference for me, but the reason for it I don't know.
