Lagging 1080 Footage
When I play 1080 HD footage that needed to be rendered back on my computer in FCP, it lags. Here are my computer’s specs:
Mac 10.4.11
2 GHz Intel Core 2 Duo processor
4 GB 667 MHz DDR2 SDRAM memoryIt even plays fine in After Effects, but I don’t know why it lags in Final Cut Pro.

[James Murphy] “When I play 1080 HD footage that needed to be rendered”
Issue #1, your sequence settings do not match your clip settings. You should not have to render the footage. What flavor of HD are we talking about here? 1080i is a size, but is this HDV, DVCPRO HD, ProRes, Uncompressed HD?
#28 Having to render every clip in the timeline
Shane’s Stock Answer #28: When I put a clip in the timline, I have to render it before it will play. Why?
Your clip settings MUST match your timeline settings. If you have DV/NTSC material, you need a DV/NTSC timeline. The frame rate, audio rate and dimensions (4:3, 16:9) all need to match exactly. In Final Cut Pro 6, this is easy, because when you drop a clip into the timeline, it asks if you want to set up the timeline to match the settings of the first clip you drag into it. Click YES and you are ready to go.
However, in FCP 5.1 and earlier, it is a bit trickier.
The most important thing you need to do is properly set up your project from the start, and the best way to do this is to choose a setting from the Easy Setups, located under the Final Cut Pro menu.
Once you do this, you’ll need to create a new sequence. This is because the sequence that is already in your new project is setup for the typical default setting of DV/NTSC, or for the settings of your last project, which might not match what you are currently working with. So delete SEQUENCE 1 and create a new sequence:
This new sequence will contain the settings you chose in the Easy Setup menu, and should match the format you captured.
ISSUE #2 – What hard drives are you playing this back on? Firewire 400? FW800? Those might not be fast enough to play back the footage, depending on the flavor.

The only difference between my clip settings and sequence settings is that the sequence is set to progressive scan. The reason I said it was rendered is because I rendered it from After Effects and brought it in to FCP.
There’s two clips in my experiment made from the same original media file. Shot on a HVX 200 at 1080i/60i. The first sequence matches the shot clip. The second clip was from the shot clip take into AE, affected at 24 fps, and brought into Final Cut Pro under a similar sequence as the first except as 24p.
I at first played it off a hard drive with FireWire 400. Then I copied it onto the computer’s hard drive and it still lags.

The computers hard drive is WORSE than an external firewire drive. It is busy with the OS.
What are the settings from AE? What codec did you export as?

Oh, and I have FCP 6.0.5.

Might be too much for the FW400 drive to handle. Normally it would handle this…barely. FW800 is better.
