Try going through this tutorial first. Also let us know where the video came from- is is H.264, DVCPROHD, DV, MPEG-2 ???

I know how to use DVDSP-

I'm wondering about quality. The project was exported from FCP to Quicktime Movie using Sorenson 3 codec- this ended up being about 2.3G

However I exported using compressor to m2v highest bitrate possible and it looks of lesser quality- and it only ended up being about 600MB.

When I just drop the .mov in DVDSP it is of even worse quality

Is there some way to keep the quality and the large file size through compressor and still make it a mv2?

Why Sorenson 3? That's a highly compressed codec for the web. You should be exporting directly from the footage's native camera format or uncompressed animation format to Compressor for MPEG-2. That was why I linked to that tutorial because it shows that workflow. MPEG-2 is MPEG-2 it can only look so good and can only be so big as you'll see in Compressor. But you definitely benefit hugely by feeding it the least compressed source footage and that's definitely not Sorenson. Maxing out the bitrate accomplishes nothing if the source is already lossy.

No I think i've confused you.

The .mov that is great quality was exported by the animator with the Sorenson 3 codec. It's file size ended up being about 2.5G

When i exported the same project (orignal FCP sequence) using compressor to mpeg 2 it loses so much more quality even with the bit rate being 8.9 and 2pass VBR. Is there a way to keep the quality level that the .mov had?

The issue may be that you are watching the original animation on the computer, which uses RGB color and can reproduce vibrant, high-resolution graphics. NTSC can't reproduce the color resolution or sharpness of a computer display, it will never look as good.

I'd be careful about the DVD data rate also, 8.9 is pushing the limits and could cause playback issues on some players. There is a point of diminishing returns - the viewer would probably never see a difference between material encoded at 7.0 vs. 8.9

yeah 8.9 would produce an unplayable disc. 7.9 is the absolute limit to get a disc that will reliably playback on a variety of players. And again- as I said above you do not want to start from Sorenson 3 as your originating codec on your way to MPEG-2. To get optimum image quality have the animator re-output as either uncompressed 10-bit or at least ProRes HQ. Put that into a high quality MPEG-2 preset in Compressor and it will look as good as it can with Compressor.
