1 hour or longer video render

Hello all, I have Vegas pro 21.

When I render a Video that is longer than 1 hour and 3 minutes, no matter what I do, the exported mp4 plays normally until that minute (1 hour and 3 minutes) and then it stops giving me a Windows error "we cannot open it seems your video has unsupported encoding".

If I add this exported video in Vegas it gets in as a whole, but after the 1 hour and 3 minutes has no footage or sound.

PS: this happens even if I render the video into small pieces, re-add them in Vegas, and try to export.

Help plz! I feel like I live in a Truman Show.

In the original project, check the integrity of all media (particualrly video) around the 1 hour 3 minutes point on the timeline - it's possible that there is a corrupt event (more likely video) that "crashes" the render at that point.

Try re-encoding and replacing just the media at that point where it stops and see if you can get through the render. I use ShutterEncoder (free) to do such re-encodes as it's fast.

I've had issues like that in the past with longer projects and it turned out to be mix-downs of wav-format audio being too large. Been doing my mix-downs by selecting Sony Wave 64 in the Render-As menu instead of Wave (Microsoft) and have not seen the problem since. Mix-downs end up with a w64 extension instead of wav. There's also a Vegas general setting I have checked, Render large Wave files as Wave64... maybe that also helps.

Thank you all for the advice, I will try those! To be exact though, it doesn't stop at a certain point. This happens to any video I render after 1 hour. So for instance in this particular case, I can render it in 4 different videos, just not as a whole 2 hours and 30 minutes video.

May be a heat related issue?
