you’d like to know what codec the file was encoded as… you can have an mov that is dv, mpeg, h.264, avid dnxhd, uncompressed, losslessly compressed, etc… if your designer used a codec that you don’t have, you won’t be able to veiw the file…. although you usually don’t get an error, you just get a white screen in the player. but it may help in troubleshooting your problem.
if you can open the file in quicktime, then choose window>movie inspector and it should say what the codec is. if you can’t, just ask the designer. most designers will use apple’s lossless animation codec… it creates large files, but it’s a high-quality, standard qt component and fcp should be able to convert it to a more useful working codec if necessary.
you mention the file is only 325mb, that is not an enormous file, but if the animation is only a few seconds, it may be that the file’s data rate is exceeding the data rate of your hard drive. that can produce jumpy or intermittent playback, like the footage pauses, then skips ahead as it tries to read the file…
