For my second run of the capture card, I hooked up the Dreamcast via VGA box. This is the first external USB card I've found that accepts VGA input, so I thought I'd make the most of it.

Equipment used:
- North American Dreamcast console (revision 1)
- Sega Dreamcast VGA box (retro-bit)
- XCAPTURE-1 USB3 capture card (VGA input)
- All games are original retail copies. A boot disc was used to load Japanese games.

A/V post-processing:
- The video feed picked up by the capture card is 720x480, but the left and right sides of the screen are pillar-boxed, leaving a 640x480 picture. I cropped out the pillar boxes and doubled the resolution to 1280x960 (nearest neighbor).
- The video was compressed using the Lagarith lossless video codec.
- The audio was uncompressed 48kHz PCM.
- The original frame rate for this video was 59.94 fps. I interpolated it to 27.97 fps, blending every two frames into a single frame, before uploading since Youtube coverts 60fps uploads to 30fps anyway, and their conversion method is very poor. The result of this change is that the footage looks blurrier in still shots, but it's smoother in motion and visual effects that alternate on every frame are preserved better.
- Therefore, almost all quality imperfections seen would be the result of Youtube re-encoding alone. (In particular, Youtube doesn't seem to handle instances where the screen is pitch black for an extended amount of time; it seems to load the next part of the video too early and freeze it there for some reason.)
