If you cannot tell the difference, then keep doing what you are doing.
For a slightly better workflow, convert your uncompressed video to Apple Intermediate Codec. This will be much smaller than uncompressed but 4 to 10 times larger than h.264. Then when you export to h.264, you will have more to work with and get better performance.iMac 24 2.8Ghz, iPhone, TV, Mac OS X (10.6.6), Panasonic HDC-SD5 iMovie 11

I did some more tests regarding the exporting an already exported video and it seems there is some loss of quality, mainly in the colour. It appears brighter and more washed out if you know what I mean. I guess the less times you compress, the better.

Currently Being ModeratedFeb 1, 2011 8:21 PM (in response to AppleMan1958)Hi again AppleMan,
When optimizing a video, will iMovie use the optimized video when exporting, or the original? I feel iMovie runs a lot better when the video is optimized. It scrubs better and plays the video nice and smooth, even when creating a picture-in-picture effect. The question is though, what does it refer to when exporting? As you know, the original files are uncompressed 8-bit YUV. There's a lot more in these files than the Apple Intermediate Codec (which still has a lot in them), but would obviously rather export using the bit rate in the uncompressed files.Mac Pro 3.2GHz Quad-Core Intel Xeon "Nehalem" (Mid 2010), Mac OS X (10.6.4), 12GB 1066MHz DDR3 SDRAM
