Q: Why am I pushing strange vertical resolutions, like 352x448 and 352x480?
A: Because I found out that it's a technique from the early 2000s codec era, often used to maximize quality within bitrate and memory limitations. Some official Dreamcast SFD (Sofdec) video files also use this resolutions approach.

Especially in this case, due to the 352 horizontal limitation demonstrated by the SFD player binary used in MIL-CD. I tested every 8 pixels until I found the operating limit. Once I noticed that the playvid internalized in the MIL-CD binary always stretches to fill the entire screen.

So the idea is to use all the possible pixel capacity on the screen, maximizing the possibility of video detail, combined with ffmpeg conversions with contrast, sharpness and noise reduction filters, for better overall quality.

This technique will no longer be desired in other Dreamcast SFD contexts, where some versions of playvid.bin use the resolution as an aspect ratio indicator.
