Trouble uploading to D-tube? SOLUTION!!!

Anyone having trouble uploading to Dtube?
This solution already helped a few people today, so I figured there could be more steemiens with similar issue.

I think it is the encoding.

I tried uploading with one of my videos that I downloaded from YT instead of the video I uploaded to YT. I know there is another solution using Handbrake but this was easier for me, maybe you too.
