Video break up problem

Hello blender community, it’s been a while :slight_smile:

I’ve been having a lot of trouble with video break up, sometimes uploading to youtube exporting from blender, sometimes in the source material. I have a canon 600d and sometimes have problems with the files from it breaking up (VLC/Mplayer), though they play fine on the camera. Sometimes blender will read them correctly other times the break-up is visible in the output.

On a second issue - sometimes the video from blender plays fine locally but will break up when it’s uploaded to youtube. For example, it breaks up at the start:

Encode settings there where

preset: h264
bitrate: 8000
audio codec: mp3
audio bitrate: 192
The rest are as default.
