Video comment not working

I left a video comment for a user here, then checked it after it processed.

It had a length of 0:00 and when the play button is pressed, it goes completely black.  

I came here to test it after I got the same result on my beta v.4 test site

How big do you think the file was and what is your cron set to for time?

I have noticed an issue sometimes with large video files and frequent crons like every 5 minutes. I think it tries to process the file sometimes before it is completely uploaded and creates the black thumbnail because it only actually captured the first 2 seconds or so of the video.

Play around with your cron a little. Find the happy medium

Nope. That's not the case.

I disabled the cron job and waited until i was sure the video was completely uploaded - which was not hard, since it was only 5 seconds long. Then I re-enabled the cron job and waited for it to execute.

Note that the same behavior happens on the demo site, so it is clearly an obvious bug.
