Need help with "file no longer exist" Error.

When I attempt to add a video to any contest it will upload and say its processing, show in the back end with thumbnail from video, but no .mp4 file will be created in entries folder.

So far the only videos that I am able to upload and play successfully are ones with this setting:
Length: doesn't matter
Frame W: 854
Frame H: 480
Data Rate: 25Kbps
Total Bitrate: 25Kbps
Frame rate: 29fps

I've tried adjusting the configuration > contests > video size and no difference. The size of the file uploaded is no longer an issue.
Please see attached images for a visual in what I'm speaking of.
