Mostly a question to the encoders out there. I've had no luck what-so-ever when it comes to encoding video game footage and placing it onto youtube, I've tried following at least 9 different tutorials, the latest one was what supposedly put Big Buck Bunny onto youtube in such a crisp sharp quality, yet my "Sonic the hedgehog" recording videos still come through like crap. So, what do I set as what to try and get a decent quality?

Make sure you give them something high quality going in. If you're using H264, use fixed_quant or CRF set to around 23 for maximum quality. This will look quite good for most material even though there's actually a huge bitrate gain. If you want good videos on youtube, you need to spend the bits on it. Don't use 2pass mode. In related news, got links? To a sample broken video or what this Big Buck Bunny tutorial says?

http://www.youtube.com/watch?v=3UeHnohnQoc - Big Buck Bunny http://www.youtube.com/user/DDRKhat I used the same settings they used in that Big Buck Bunny video. For the input video I recorded completely uncompressed. Then encoded it into mp4 with H.264 compression 100% qulaity @ 2000 kbps (MPEG-4 AAC Stereo 256kbps sound) frame limit of 30 fps. no scale changing.

Most of this makes no sense at all, though I agree he should be using CRF at 20-23. I have a tutorial on encoding for YT, and it's working well for me: http://www.youtube.com/watch?v=BS3sqGcmGFg&feature=channel_page

What form of video do you go from, uncompressed.. or what codec settings, Joannes? it seems you do have the HD luck that that tutorial page speaks of, it'd be nice if I could finally conquer YouTube's annoying system and get decent quality videos onto the web. Edit Wow, thanks alot. I took one of my already recorded videos ran the process and viola, it's a brilliant quality! Thanks a huge bunch! p.s heres a link to the test video http://www.youtube.com/watch?v=y5H_ZFY_oaA&fmt=22

I always upscale my videos to 640x480 using h264 lossless. It makes them take a lot longer to encode and upload, but the quality is far superior to how it looks otherwise.

But what do you record them at? h264 lossless . then upscale? or what?

Does the high quality mode from youtube have limits about fps? I know that TAS encoder guideline would prefer full FPS. ..So, get the full FPS in high quality youtube mode and let's youtube encode by hiself at 29.97fps for the "crappy mode" should be right way, to do?

I once uploaded an 80fps video on youtube, and, even in HQ mode (&fmt=18), its frame rate has been reduced to 60. So yeah I think 60 is the limit.
Gone.

I'll try a 60fps encode sometime

I take back what I said the other day. I've been doing several checks by downloading several videos with keepvid, and I found out that the HQ versions of the videos (&fmt=18) are capped at 30 frames per second, while the LQ versions aren't. Which is, lol? Now you decide, higher frame rate with lower resolution and quality, or lower frame rate with higher resolution and quality?
Gone.

Lower framerate with higher resolution would be my suggestion. Videogames really don't look good in the blurry can't-see-pixels detail level of the basic encoding. It's good enough for stuff where you don't need fine detail, but practically everything made here does.

Except the fact that YouTube's "low" resolution is equal to or higher than the standard resolution of pretty much every console represented on the site. The problem with it is low bitrate, which is the thing that makes encodings blurry for the most part.

Bah, terminology. :) All I know is, the default encodings look like crap, but the high-quality ones are much sharper (and thus, much easier on the eyes).
