[Jeff Greenberg]

Have you tried reducing the playback resolution?

No, as I said, I am a newbie and I didn’t know you could do that? Is that like After Effects where the image quality gets reduced quite a lot?

Thanks,

Right click the Program monitor (or look under the wrench).

This reduces quality only during playback – the paused resolution is full quality.

I used to cut picture at very low quality; this is miles above it.

It’s similar to AE’s 1/2 or 1/4 res; but the moment you pause, full quality.

I did that and still got some lag. I am beginning to suspect that it is a combunation of factors. One being that I am using an external USB drive. It is USB 2.0.

An easy way to test the drive speed is with Black Magic or AJA’s disk test.

I never did ask. What format and how many streams of it are you trying to playback? Did dropping the quality help? Is it at 1/4?

It was one video that is 1080i. It was an uncompressed .avi. In the standard def world, .avi’s were less problematic.

I only have options for full, 1/2 and 1/4. 1/8 and 1/16 are greyed out.

Lately I have been changing to High Quality .h264 video out of after effects. For some reason I just can’t get decent reults with .mov files???

In the last few months I have been experiemtning with the best formats for HD. I do a LOT of After Effects work that I then render out to do final editing and post in Premiere Pro.

Unless you’re over HD, you’ll only get 1/2 and 1/4.

If you’re working with After effects, either render as a editorial codec HD (such as ProRes or DNxHD), especially if you want to keep your alpha channel. Adobe Premiere Pro can dynamically link to AE – so you don’t need to render for Premiere Pro (from AE. You may want to render in Premiere Pro for playback.)

Also, an uncompressed AVI, will require a drive speed of around 100 MB/sec (over 800mb/s.). You’d need 4 of your drives RAIDed together to get that.

I had no idea about dynamic link! I had seen it, just ran a test, premier has to render it to be able to use it and that render is almost as long as just outputting the file.

I wonder if you could expand a bit on “editorial codec HD (such as ProRes or DNxHD)”

I don’t see those opetions in AE’s render format options. I saw a tutorial where the guy used a “Video Stream” from the export function, but I don’t see that in AE CS6 export.
