The --touhou settings (changed again) is due to Dark Shikari. <3 Dark Shikari. it helps with some block, getting a bit more qual with little bit less size.
For local stockage, --placebo works well (old insane afaik).
On an interesting note, I'm upload to youtube some of my vid (I'm not a good tōhō player myself, nothing to brag about
I did some quality test.
Youtube massacre the quality of 480p game (640x480 for tōhō, for example), to keep a nice quality you have to upscale into 720p.
it's pretty easy, use a spline64 resize, and edit manually the .avs spline64(640;480) into spline64(960;720). Not sure of the exact syntax, I'm not at home right now.
That way, the replay are quite watchable in 480p, and even better in 720p.
I could link my channel for you to observe that, but I'm not a youtubewhore (so I will not if not requested).
Another interesting thing with youtube is that they reprocess the vid into A 30fps one. To lighter the upload, there is noneed to encode into 60fps.
I use basic framedrop, with virtualdub, before the x264 encoding (video > frame rate > source @60fps; output at 30 ;; again I'm not sure of the exact syntax but it's close to that).
Is someone know how to resample the video with motion blur (better then framedroping for quality) with uncompressed / x264 project, I'm interested.
