Final cut pro 7 viewer video running slow (Strobing)

Does this happen with all the clips you load to the viewer or just some?

Click on a clip (that is strobing) in the FCP browser to select it, and once selected, type Command + 9 to see the item properties for that clip.

Either report those properties here or take a screen shot of the item properties for the clip and post that here.

h264 is NOT a suitable format for editing in fcp. Use compressor to convert to the appropraite flavor of prores

Describe exactly how you tried to do this Works for me all the time.

Hey! I have the same problem. How do I use "compressor to convert to the appropraite flavor of prores"? I red all discussion but I got stuck here... Thanks!

bring the problem files into compressor. Apply the apple: format: quicktime: prores422 (this should give you good quality). If the audio in the file is compressed you'll need to enable audio in the encoder panel and make sure it's 48k 16 bit.
