If you manually enter a number in either the height or width setting, as long as "Maintain Aspect Ratio" is checked the other setting will be calculated. However, those figures don't exactly fit a 4:3 ratio, so uncheck the "maintain" box and manually enter both figures.
Also, after you apple the Generic Web filter, double-click it in the render queue. That filter also automatically crops the image, plus changes the brightness, contrast, and gamma. Generally, if you're producing video from a digital source, you don't need to crop (no overscan garbage like with an analog format), and presumably, you've already tweaked your levels. You can create a custom filter that only deinterlaces, and use that instead.

Thanks CB.
Damn. I'm getting an error out of Sorenson with that Web filter. Wouldn't you know. Something simple is going to be two day's work, I can just smell it.
Do I really need to deinterlace with a Web filter? I went back into Avid to see if I could do it there by applying a Fluidfilm effect to the timeline, but of course I can't seem to apply any Timewarp to a sequence with effects in it. And all the work is done. So I can't undo those effects first.

If your footage is progressive, there's no need to deinterlace. In fact, your output will probably suffer. If it's interlaced, though, deinterlacing is going to help you get the best output.
Try creating a new filter preset. Right-click (I think?) over in the presets pane, and select "create new filter" (or whatever it says). Then, turn on just the deinterlacing, and save. See if you can apply that filter and get the output to work properly.

It worked! I applied a custom filter as you suggested and the deinterlacing worked (everything else was left unchecked)! Thanks CB. Turns out it was the "normalize audio" step in the Generic Web filter that was causing the error.
The footage was HDV from the HV20, transcoded to DNxHD. So although it was originally shot progressive in-camera, it was then recorded to tape using the 1080i codec of HDV. I have never de-interlaced it, so it's interlaced alright.
I'm curious: is there something about viewing on the web that exaggerates interlacing lines? I didn't see any interlacing artifacts in Avid, QuickTime player or After Effects.

no but Avid likes to exagerate them
you'll have to do video and audio mixdowns in Avid before exporting the ref files for this to go away. Same with authoring.
this'll kill a brother doing an uncompressed longform without enough space to double it when done.
crazy. I purchased my adrenaline wanting to take HDV in nativly and then be able to easily spit out nice authored DVDs when done editing.
still waiting for that to be the case. Looks like I will upgrade to FCP before Avid comes around to delivering what they advertise.

Aw, you've really got hard on Avid lately grinner. But it also sounds like you're pretty experienced with Avid and have legitimate gripes.
So you're saying that a video mixdown/transcode to DNxHD deinterlaces the footage? I must be misunderstanding. I did transcode from HDV, and then exported the QuickTime Reference file from there. Fortunately a small project, so doubling the media files didn't break my hard-drive on this one. And my life with HDV is probably coming to an end anyhow.

man, they've been hard on ME.
I've been a goo sliitle editor, making fine payments to em for many many years now. Been on an Avid product for 15 years.
Now, they insist on running me off and increasing FCP's stock.
I'm just an artist. I don't have time to trouble shoot short cuts engineering depts make. I have clients I gotta please and Avid has stopped making products that make this easy.
