Thanks to others in this great forum, I am learning the virtues of VirtualDub!... I was wondering, though, what people here recommend as the best deinterlacing filter for VirtualDub (I know there are many of them)? And what would people recommend as the best cropping filter?...

Thanks again for your input!...

Well that would depend on the source.

For a start, unless the source is RGB, then I wouldn't recommend using VDub to deinterlace, resize or do any filtering. The reason is, that to use filters in VDub, you have to enable full processing which means converting to RGB24. So if you are say converting a DVD to DivX/XviD, then that means YV12-->RGB24-->YV12.

For such sources I would instead recommend using AVISynth.

So, it's better to use a codec's internal filters?...

Thanks for the word of caution, celtic_druid... I had read elsewhere that not only was it a longer task in transcoding a video by converting color palletes (going YV12 to RBG24 back to YV12), but it also doesn't produce as good results.

So, if I am to understand you correctly, it is better to use a codec's internal "filters" (ways of changing the original video, such as cropping, interlacing, brightness/contrast, etc.) than it is to use VirtualDub or AVIsynch filters? I suppose that makes sense, since the codec creators already know how their adjustments work on their own codec. I suppose the only reason why one would want to use VirtualDub or AVIsynch filters is if you desire a particular change but the codec you're converting/transcoding to doesn't support those changes.

Is that a correct assessment?...

No idea where you drew your conclusion about me not recommending AVISynth.

As long as you are using AVISynth v2.5.x (latest is 2.5.3 at least it was a few hours ago) then it supports YV12, YUY2, RGB24 and RGB32. In order to make use of YV12, make sure that you are using a newish version of VDub or VDubMod as older versions of VDub did not support YV12.
