My archive H264 files are NTSC-SD format (720x480) and have vibrant sound, color, and picture. I did this for the Nationals, Olympics and Worlds. The only difference from the original is slight loss of fine detail and slight blurring with quick movement (noticeable in the figure skating videos). But these files are huge. My Kimmie Meissner 06 Worlds FS file is 113MB (but then, that also includes the replay and scores).
