[dolver] “I have a 15 second dv clip (using consumer canon camera). I need the video to be as CRISP as possible, regardless of file size.”
If you don’t like the “cripness” of the image playing directly from the camcorder out to a monitor, you’re not going to IMPROVE the image through capture settings or file size.
Don’t expect a lower-quality image to become any “better looking” (crisper?) than it does on the monitor coming from the camcorder.
You should capture, edit and output with the “Easy Setup” in “DV NTSC” (or “DV PAL” if that’s the part of the world where you are).
Once you’ve captured, you can add the “Color Corrector 3-Way” filter, the “Sharpen” or “Unsharp Mask” to increase detail (and NOISE) or any other filters you’d like, but… don’t expect adding video filters to make a “home video” image look like high-end camcorder footage or to increase its resolution detail.
