Hi,
since many people work with final cut to produce content for pandoras box I would like to share my experiences in exporting.
After testing around a while I figured out that the best result is to export the clips as quicktime movie using the Photo jpeg A codec. This codec is a standard apple codec, so every Final Cut express and Pro Version is able to export using that codec.
The best is to leave all the settings to the original, so that you change as less as possible. So stay in the same framerate and resolution as your original file. If not needed, uncheck the Audio.
After that load this clip in either the mainconcept encoder or the new Pandora Box encoder and reencode it into mpeg elementary video. This will generate a mpv file wich will be played back by Pandoras Box very smooth and nice.
One more advise for peole recording with their own camera. Make sure to do a proper white balance. This will make colour correction much easier. And also check the framerate you work with. If you want to have smooth movements you should use 50 fps. Using less than that might cause a jumpy picture. And also record in progressive mode. This way you do not need to interlace the clip afterwards.
best regards
Patrick
