1 drive (RAID-0) or 2 drives for hard disk performance

[Jeff Pulera]

Hi Gene,

RAID 0 should definitely provide better performance than a single drive. What format are you working with? If AVCHD (H.264), this can be very taxing on even a fast system like yours, you are better off using an intermediate codec that is more edit-friendly. If uncompressed, you may need a special external raid drive to keep up.

Thanks for the quick response! I am using a Canon 500D (I know, I know, video should be done by camcorders and not DSLRs, but I’m just starting and I don’t have the budget for a good HD video camera) but it records 720p30 as *.mov files. Since I’m a noob, I’m not sure if that is considered AVCHD, but I do EXPORT to H.264… but that’s after I edit, so I guess it doesn’t matter…

Thank you very much, Vince. I’m at my day job right now (video editing is a new hobby of mine) but I will look through those posts. I have a big feeling that the drivers ARE the issue. I already had an issue that I resolved by turning off OpenGL (AE kept crashing whenever I did anything in 3D mode).

Thanks!!

Vince,

I tried to install the old drivers, but the most previous driver I could successfully install was the Catalyst 9.12 version (dated 12/17/09). I think this is because I have a 5700 series graphics card and not a 4800 series.

Am I going to have to wait for new drivers? Or could it possibly be a hardware issue? I did some more research and some guy seemed to fix a similar issue by overriding the voltage controls and keeping them higher…

ATI is really getting on my nerve now… argh!

You could try removing the drivers completely and let Windows find its own.

Are you previewing on a second monitor?

Thanks for offering help on this. I appreciate it a lot.

No, I am not previewing on a second monitor. And I did uninstall the display drivers cleanly and reinstalled (many times actually). I even went as far as letting Windows (I use Windows 7) load their generic drivers and didn’t install any ATI drivers. I opened up Premiere (in 800×600 mode) and I STILL had the same very laggy video preview playback!

I also did this: I reinstalled the ATI drivers and opened up the Catalyst Control Center to monitor “activity” under the ATI Overdrive section. I noticed that the activity mostly stayed at 0%.. it sometimes went up to 1, 2, and 3%, but that was it! Even when I opened up a movie file I had on my computer, the activity would reach more than that (at 5%).

Right now I’m about to do another test… run a 3D game. I’m downloading a playable demo version of a game right now. I’m not a gamer at all, but I want to see if the graphics card (which is pretty much designed for games) has any problems playing the game.

Does it sound like a hardware issue to you now?

Do you have any DV material to test with?

Good idea! I have some on another computer… I will see if I get that preview lag with those files also.

The only effect I used was I used the Linear Swipe effect to do a triple split screen (I used it instead of crop because I can feather the edges). So three video layers and NO audio layers… 1280 x 720 pixels, *.mov files, 30fps.

I’ll try a similar test with the DV files and see what happens.

[Gene Lee]

Okay, I tried a test with DV footage, and there wasn’t much lag at all (especially compared to when I was doing it with 720p footage).

So what does that mean?

(BTW, I’m about to try installing that game demo)
