When we encode with cromoresample we get 1-pixel-thick artefacts. If the picture was not resized, they make a certain % of picture destroyed. But when we resample AFTER resizing - the % of picture destroyed lessens. Also, as 1 or 2 pixel wide objects look like crap in SD, in HD only a small part of them is destroyed.
That's what I explained above, but you don't need HD resolution to fix this. Just a resize of 2x in both directions already fixes the chroma problem.

Another would be multilayer backgrounds.

I'm working on one. It will take some time. The crash my system experienced didn't help it.

What's wrong with the current encodes?
The YouTube link was resized wrong and had a shadow error near the beginning of the run.

Take a look at the SD encode then, and watch it completely. You'll see everything's alright.
That explains why it sounded off when I watched that run. Now I remember! =p Just kidding, never watched it =p

That sound desync problem happened to me when I was encoding [1631] PCE Bonk's Adventure by jerfo in 24:03.63, and I could fix this easily.
This problem should have been brought up then. If it was brought up, I have missed it. Anyway, if that was the solution, I would like to know what other things were tried before trying that solution. This also means that the published encode might be incorrect...

I don't think this is the correct way. We should really find the underlying cause of the desync

As Mister Epic said, that's only his personal preference. The real reason that HD videos popped up was due to YouTube being very crappy in quality. Upping the resolution was so that the video gets more bitrate and hence less quality loss. The other minor reason is there is less loss of colors due to the YV12 colorspace. Basically, due to the codec we use, the color information is lost (around 1/4th the original). Since this is pixel art, it is usually very noticeable. A simple fix to this would be a 2x resize, but obviously a bigger than 2x resize can also fix this. On a side note, I've noticed YouTube has up the quality on lower resolutions recently, maybe HD encoding isn't needed anymore. Also, I personally see HD encoding as useless.

There is a mistake. The color conversions should be like this:
ConvertToYV24(matrix="PC.601", chromaresample="point")
ConvertToYV12(matrix="PC.601", chromaresample="lanczos4")

Another option is use FFmpegSource2. This can also read MP4s/MKVs

That's not a good solution because DirectShowSource is not frame accurate. I would advice against using that.

BTW, Avisynth has a limit of loading 70-80 AVIs simal, before it cramps out. Not really an Avisynth limit, but more a VfW limit. Your 116 AVIs is not going to help this. What I usually do is open and append all AVIs in VDub and then save that to a new super AVI. Due to your lack of space though, this won't help you much...

Finally! I see this stuff is unstreamed. I'll make an HD encode for that, but if Aktan (or anyone else) is making the official YouTube stream, please reply and tell me to stop.
Uh, it is streamed. Maybe you meant not YT streamed? Anyway, I'll be making two other resolutions of 640x480 and 1920x1440 with Archive streaming.

I didn't even know it was softsubs. Yea it should be hardsubbed, IMO.

Sorry guys, found another error. The screen has been shifted down 7 pixels. Dang Famtasia encoding is tricky. Anyway all files have been replaced yet again. Enjoy!

For the record, H264 does not suffer quality degredation with high keyint values the way MPEG4/DivX does. You lower it to provide good seek capabilities.
Actually it does, you get the pulsing effect. It's partly why opengop has been added for blu-ray due to the fact blu-ray requires keyint to be a keyframe every second or so.

If you like MPC-HC to playback the videos, you may want to try this: http://tasvideos.org/forum/viewtopic.php?t=9964&start=40

First, I did what Aktan wrote. It helped, but now, I hear random sped up sound from the game. Still no video. Then, I've unchecked "Show FPS display on startup" like BadPotato said. Same thing. And also, here is the log. Here is more information... I've got a CCD/IMG/SUB dump from Megaman X6, and I've loaded the IMG file in the TAS ISO Plugin 0.2. Does it matter?
The log suggest the sound is screwing up. Weird screw up though as I've never seen it do that before.

Uncheck "Show FPS display on startup". I had a problem similar to this before: ==> http://tasvideos.org/forum/viewtopic.php?p=225515#225515 Also, I recommend to use a better audio plugin with desyncless savestate, even if this is harder to make(thought apprently the issue is somewhat fixed).
Actually that was checked for a reason. It's to find which frame desyncs. But if it works without, dang, that is weird.

Probably won't affect it, but for the TAS GPU, Dithering should be set to slowest. Again, probably won't affect it, but TAS SPU I have set to 2, 1, 2, 3 For .kkapture, I have "BASS/FMOD interception" unchecked and "Separate encoder thread" checked. Also checking the log .kkapture makes will help out a lot.

P.S. Whoever came up with this text that was added into the publication text was rather clever. It is a good question: "Of course, upon watching this movie, one does have to question something... is it Mega Man saving the world? Or Dr. Wily trying to save it from absolute destruction?"
I think that was a paraphrase of a comment that was made on YouTube. The comment was "dude if this is what happens when megaman saves the world, maybe wily isn't so bad".

While I think it is possible, I think you would need to use ScriptClip to achieve it. It be basically changing the subtitle position per frame, which is what SciptClip allows you to do.
