Thanks for all your help! It was indeed the h264 codec. I had thought that my assistant editor had changed all that for me (using MPEG Streamclip), but he never got to it. Sigh. Now I am much edified.

Again, thanks for the help!

Yep, you seem to have the gist of it. I AM editing using h.264 files. But I just noticed something significant:

Started a fresh project. Popped in cuts, with only the occasional minor dropped frame.

Added a fade at the beginning of the sequence. Rendered it. And voila! Now EVERY SINGLE CUT has significant dropped frames (almost a second).

Delete the fade. STILL every cut has significant dropped frames.

Restart FCP, and things are back to the way they were.

Conclusion: something happens during a render that upsets the playback. It smells very much like a FCP problem, not a codec problem, and almost certainly not a hardware issue.

Am we the only people in the world experiencing this? There have to be others.

System: imac
3.06 Hhz Intel Core 2 Duo
4GB 1067Hhz Ram
4TB fireware 800 HD (2 disk RAID 0)
FCP 7.0

Okay. It seems like we have NOT figured out the rub of this problem. I have been working on other projects (not editing), so I’m no longer fresh on this topic.

What we need are new eyes and new ideas here.

Another day of tweaking.

I’ve made a test that does NOT have the hesitations/pauses at each edit.

I stopped using my brand-new 4 TBytes firewire800 external hard drive. By moving all my files to the main drive of my iMac, I no longer see a hesitation.

Perhaps playing with the cache??? Hmmm. The firewire SHOULD be quick enough–didn’t occur to me before.

Please let me know if anyone else has experienced anything like this.

Sorry, the previous posts were only temporary fixes. The damn program delays just as much as before.

Help!

Anybody, anybody? I’m beginning to think that working with Premiere wasn’t so bad.

Hey, I just tried something that seems to either have worked, or helps a LOT!

On the Canvas window, in the right-most pull-down menu make sure that “show overlays” is unchecked. Mine was on. I turned it off, and now I’m no longer seeing the transitions.

Don’t know what fcp calls an overlay yet, hope it’s not something terribly important.

Good luck,

Uh, yeah. Me too!

I’ve been experience the same problem: during playback the video stalls for about a second at each and every cut, making editing…pointless. Sound plays fine.

By changing the playback setting to “low” helps, but the hanging still sometimes happens, although with much less of a pause.

I’m using 1080i video shot with a Canon D7, my computer is a brand-new iMac (recently switched to the mac from PCs and Premiere, so I am still learning the fine points).
