Hi
I have a complete film that I have converted to an MP4 format which is fine for uploading to Youtube.
My problem is I have lost the original clips from the original project. I now want to put another track from another project with the MP4 track, If I do this will I have to convert the whole film with the extra track as an MP4 again. I'm not sure if you can do this, and would there be a loss of quality in the first MP4 track.
I have tried to upload an MP4 to YOuTub with just another track attached but I new this was not going to work,
Regards
Michael Blount
