Optimal video upload settings

I've been trying to upload some quicktime .mov files and getting a little pixel drag in the embedded versions of the video. Are there optimal settings I should set my .mov files to before uploading? Any information on how to maintain that most amount of video quality would be very helpful.

Thanks!

Quicktime

Hello,
We have found that using H.264 compressed Quicktime files work best with our platform. Set your compressor settings to 2-Pass, High quality H264 for encoding. Thanks for using VideoBloom.
