Describe the issue
Often times when transcoding to an MP4 profile one of the chunks of an encoding will come back as an encoding fail but the video seems to play fine if I pull the actual encoded file. The logs don't show any errors and look the same as successful chunks, Retries is 0, Status is Fail, and Total run time is also 0. But then if I click on Encoding file it plays just fine and everything looks okay. I also never see this with VP9 encoding.

To Reproduce
I'm not sure how to reproduce this. However, I did not see this problem until I moved to a server setup with much higher capacity but also higher disk latency. I've raised the timeouts for Celery to allow each task to run for considerably longer, far longer than successful chunks take to encode, but the issue persists.

Expected behavior
I would expect that the chunk, which from everything I'm seeing did in fact succeed in encoding, would be marked as Success instead. What I find most odd is that Total run time is 0 - seems like even for a failure, that should be filled in with some kind of a value.

Screenshots
Can't share screenshots of this setup unfortunately.
