I’m using Kdenlive 0.9.10 and there’s no YouTube profile under “render”. I am not sure how to implement all the settings in YouTube’s recommended settings: https://support.google.com/youtube/answer/1722171
For example, it says “No Edit Lists”, and have “moov atom at the front of the file (Fast Start)”. I don’t know what those mean or how to ensure both of those cases are true.
I have been unable to find a tutorial online that does this.
No idea about Edit lists, but shouldn’t be hard to find out.
A search for “moov atom” yelded a nice explanation here: http://dinaerteneto.com/2012/10/05/conversao-para-mp4-h264-com-ffmpeg-moov-atom/ (in Portuguese, however), but with these links:
App to move moov (ffmpeg leaves moov at the end of the video, impeding streaming):
Google Code Archive - Long-term storage for Google Code Project Hosting.
