Uh, hello.
So I've been trying a handful of various methods of converting 60fps videos to 30fps. I have for years, actually, off and on, and I figured I would share what I have figured out since I am no longer inexperienced with AviSynth.

This is published video #830, Super C, in a quad video like the NES Mega Man video that blew my mind. It's all sourced from the same (lagarith/rgb) dump. I have no idea on earth what the sound output from the .avs file is like; I simply loaded the source dump alone and dumped the .wav and used Nero AAC to make the actual .m4a I embedded into the .mp4.
For encoding I used AviSynth/VirtualDub/x264 VFW (writing to a separate .mp4 file) and "My MP4 Box GUI" to merge the video/audio. The bitrate is ludicrous so you can expect little to no artifacts in the compression; this is a showcase, not a publishable thing.
I guess this is useful for watching specific parts repeatedly while focusing on different sections to see how flicker/motion is handled?
Generally speaking, I have almost zero idea what in the world I'm doing.

There's the .avs script I pieced together with a hammer and a block of cheese.
I love these movies and I have a tendency to be uncontrollably obnoxious which is why my post count is so low; I love this site and I love what you guys do, so, I just stay out of it as to not ruin it for myself. But in any case, I figured I'd share this since I worked on it for a bit.
I guess I'm up for answering questions if any pop up, it's all pretty well explained. I'm still looking for/playing with other motion compensation methods. If someone wants the plugins I suppose I could slap them on mediafire pretty quickly.
So, um, yeah. >_>
I know the community has voted against this sort of thing but I have a habit of making personal .mp4's for my phone and I figured there might be other people that do as well. IMO the frame merger plugin wins because it's so subtle, it tends to not blur up fast motion the way other methods are prone to.
