In the following video that I've uploaded to my YouTube channel, a still image from the beginning of the video flashes for 1 frame many times throughout the video. Here's an example right after the 5:48 mark:

The original video stored on my computer (that I uploaded to YouTube) does not have these "glitches".
I reported this to YouTube and they are working to fix the video, so by the time you read this, the problem may no longer exist for this particular video. However, I've seen a few people complain about a similar issue, and so I'm asking a question about whether there is something that can be done to minimize the probability of these glitches?
I'm using 30fps, 1080p, H.264, generated by Premiere. Original video is 59.94fps, but again the exported video at 30fps looks flawless on my machine.

YouTube regularly messaged me (once every 2 weeks) letting me know that they are working on a fix. Now, 2 months later, they said that the bug is fixed. My video appears to be good now and hope the same is true for other videos that experienced this bug.
