Here are some guide lines for supplying us your video as trailers
Can you recommend some encoding settings for HD?
We recommend using the Quicktime H.264 codec at size 1280×720, bit rate 3000-5000 kbits/sec (optimized for “download”), key frame every 30 frames (frame reordering on), using whatever frame rate you shot in.
For sound, use AAC at 128kbps in stereo.
Should I deinterlace before I upload?
It’s almost always a good idea. If you’re outputting 1080i, deinterlace and resize to 1280×720 before you upload. In many cases if your final outcome is a progressive medium (web, LCD TVs, HD-DVD, etc.) you might be better off deinterlacing before you even start editing.
