I'm having trouble correctly viewing the output pane AFTER compression/codec conversion. I'm trying to convert my source video (xvid) to h264 using x264vfw, but I can't preview the output correctly.
For my test, I just took a video of a game recording and tried setting it to the lowest quality possible. My settings: http://puu.sh/9ufE8/458a78b9b4.png
As you can see in the background, the quality is at the level of the input video, and my video settings are definitely set to "Full processing mode" and not "Direct stream copy" as seen here: http://puu.sh/9ufJU/b8102d108e.png
The resulting output file renders out to be low quality, though (as intended): http://puu.sh/9ufNo/dedbd73b74.png
Any ideas on why my output/preview pane isn't actually previewing the "output" video?

The output pane would be previewing the output of the FILTERS that are applied to it. It DOES NOT EVER show output AFTER compression encoding (at least not in Virtualdub).
So, to repeat - make sure you:
1. Have the [View | Input Video pane] checked
2. Have the [View | Output Video pane] checked
3. Have the [View | Swap input/output panes] UNCHECKED
4. Have the [View | Pane Layout | Both panes] checked
And I just confirmed, if you have a null transform filter in line, your videos WILL and SHOULD look identical.
The output pane is NOT meant to be a "compression" preview window.

The output pane only shows the effects or filters applied to the original video.
It doesn't show what the encoded video will look like, for that you have to encode a sample and open it in another video program.

Maybe the swap panes tab got checked ?
VirtualDubMod has an option "Show decompressed video - Shift+F10". But I doubt that it will work as expected with modern video formats with complex dependencies (B frames, multiple references, etc.). It relies a lot on the specific VfW codec as both encoder and decoder. Intra-frame only codecs (MJPG, DV) may work quite reliably. But in general, it may only display it during a dubbing in progress, not suitable for framewise previews.
