FCP HD playback slow to start/stutters
I am subtitling a clip that is an HD imported QT clip. I have all the latest codecs and whenever I play NTSC video I do not have this problem. With the HD clips, whether they are from the cf card or an imported quicktime, when I play this clip it takes several seconds to start (whirligig thingy twirls for 5 – 10 secs) and often stutters thru the playback. I have unchecked the warning for dropped frames and checked my disc space. I am new to HD, so please bare with me. I am including screen shots of the pertinent settings….at least I think they are pertinent. If anyone can please tell me where I might have a wrong setting or what else I should look for? Subtitling is tedious enough without this slowing me down! This system should work fine with HD!
Thanks for your much needed help!

CF card? Are we talking about a DSLR here? Did you transcode the footage properly through Log and Transfer, or take it straight from the card in it’s native format?
-
I should’ve been clearer. This also happens with footage pulled from a CF card….yes, that has been imported with log and transfer….but in this case it is a Quicktime movie that was sent from the client.

This is an MPEG-2 file. You can’t work natively with this. Convert it to ProRes.

I see. Ok. Am using Mpeg Streamclip to convert it now. Will see how that does. Thanks!

Yep. Much better. Still has to think a second but much better. It plays thru and I can easily step thru the clip. This is what my converted file became.
Thanks much!

Ok much better playing thru the sequence but it still takes a few seconds to start playing. If I play it from the Canvas play button it thinks a few secs then stops after playing a frame or two. If I play it from the timeline or the keyboard the whirly gig spins for up to 10 secs. What can I do to make it start more instantaneous?

You don’t need prores HQ. Just try regular prores. HQ is really only for frame sizes bigger than 2k.
Try it out and see if that makes a difference. At least it will cut down on file size and bandwidth.

I wouldn’t say that HQ is just for large resolutions, but yes, you can probably use regular ProRes for your purposes.
Also: where are you storing your media?
-
ok. Converting again without HQ.
The project is on my external 2TB firewire drive which has more than 1 TB available. However, the converted clip was saved to my main drive.

Are you able to run a speed test on that external? Might be as simple as the drive isn’t fast enough to keep up with HD. How is it connected?
