I tried this myself and understand what is involved. For someone experienced, i don't think this is more than a few hour project.
I want to take a number of videos from Youtube and create my own video which will be about 1 hours long. You don't need to create it from scratch.
Provide the link on youtube
the footage i want included. from the link i will give you the start and end time within that video.
I will provide several videos.
I want them assembled so they transition properly between segments and look professional.
Like i said, this overall is a small project that should not take someone long to do so keep that in mind with your bid.
