...just wondering if someone could test the following, which may be useful for others interested in video on Snow Leopard and QuickTime X... The trim feature, is it lossless? In other words, does it trim to the nearest 'I' frame, therefore no frames are re-compressed, or will I still need to use a third party piece of software such as MPEG Streamclip for this functionality? I guess the easiest way to discover this would be using a HD video clip. The time it takes to write to disk would be a clear indication of a lossless clip and save vs a clip and render. Cheers! Lee.
