For anyone interested, you can go to the Samsung developer's site and download their theme building software for feature phones and use it to make qmg files. It has worked on the S2, so it probably can be made to work on the Victory. I tried one unsuccessfully, but I didn't pay attention to image dimensions, so that may have borked it. It may have to perfectly mirror the size and time of the original in order to work with the bootanimation binary. I haven't tried another one yet, been busy deodexing the stock firmware, once I do I'll post the results.
If we can't get it to work on the Victory, we can always write our own bootanimation binary and repack it and the necessary changes to init in the boot image. This would allow me to port my bootanimation chooser from Gingerbread to the Victory's JellyBean, so I would prefer going this route (also allows for PNGs and JPEGs instead of having to convert to RLEs and/or QMGs).
