m35, I exported with highest settings to yuv, and this file wouldn't load in Sony Vegas? What about exporting to bitmap images again? Isn't that also uncompressed and top quality?
Are you serious?
Sony Vegas doesn't support YV12 color space? That's very disappointing, and now I'm not sure what to suggest.
* Pretty much every good codec (e.g. h.264, xvid, etc.) ultimately wants the video data in a YUV color space. The video data from the PSX disc is already in a YUV color space so I hoped to skip the intermediate RGB step altogether.
* Additionally, I recommended using jPSXdec YUV export because jPSXdec can only perform a very mechanical YUV->RGB conversion, so the quality suffers. Skipping that step saves us from that degradation as well.
* Finally, converting the jPSXdec YUV export to RGB using another program
also degrades quality because the YV12 YUV color space is smaller than the RGB color space, so color information is lost in the conversion.
If you need the best quality RGB, it's, well...not available yet. I didn't think I would have to tackle smarter YUV->RGB conversion in jPSXdec because I assumed the simple YUV export would be good enough. But now it seems there are cases where RGB is still necessary. I'll add it to the TODO list, but can't say when or if will be implemented.
The only option right now might be to use another program that can work with YV12 color space.
Note: I'm somewhat of a videophile. There's a chance no one would even notice the degradation of qualities identified above. Try them out. Maybe it will be good enough after all.
