Having completed the final edit of your documentary, you will need to export it in a suitable format for uploading to FourDocs. If you are using Avid’s Xpress Pro, then you should export your film as a QuickTime movie, using the MPEG-4 codec. Here’s a step-by-step guide to help you.
Once you have saved your film, open a new folder on the desktop, call it something like Exports. This is where you are going to save all your trial exports to, as you will probably need to experiment a bit to get the best possible quality.
Make sure that you mark the first frame of your film as the in-point (go to the first frame of the timeline and MARK IN – press i) and the last frame of the film as the out-point (go to the last frame of the timeline and MARK OUT – press o). This makes sure that you have selected the full duration of the film. Now you're ready to compress your film.
Start by choosing Export from the file menu bar.
