HD Preview through AE 7?
We’re doing a HD-projekt in AE but I seem NOT being able to get full 25fps previews.
Media is 10-bit 4:2:2 1080i50 QuickTime.
We’re using AE7 on a Quad G5 with a Kona LHe card and a Med

How much memory do you have? Also how long are the sequences? I’m running uncompressed 16 bit files at 1080i and getting pull playback at 23.976. My shots are only 5 – 6 seconds in length though. I am using the maximum 3GB of memory on a Mac G5 2.7ghz dual. As far as I understand RAm is what affects what speed playback occurs at…Could be wrong though.

I have 2.5 GB and only previewing around 1-5s of video.
Running SD works perfect, HD gives me around 22.5 fps of the 25 I “need”. Turning off video out doesn’t make a difference either. It’s 8-bit comp I’m working on now.
Exporting the RAM-preview and opening it in AJA TV works fine however (and that’s playing from disk!)
Really strange

Neither of these are good options. They get the work done, yes, but they don’t get them done “good”. 50% resolution will give me blocky previews on the HD monitors (and probably look weird when scaled down by the Kona-card to SD).
How do I get a faster computer than a Quad G5?
AE might be outputting 4 times as much data (wrong, more than that actually, almost 5 times more actually) but so is FCP. An exported RAM-preview plays fine in QT player or AJA TV.
Oh well

Oddly enough, when I do a RAM preview in any resolution less than full, I cannot watch realtime previews…that really surprised me.
I’m amazed that you can’t get full previews on that machine. You might be slightly down on RAM (500mb will probably help) but you’d think it would work…
One other, very important and possible solution is the Graphics card – AE7 is supposed to utilize the Graphics card to processing and previewing (I’d guess that would include RAM previews.) What card are you using? I have the X800.
Good luck. I wish I could be more helpful.
