Hello.

I have a problem - any my Arma 2 video become crappy on YouTube. I've tried different settings and codecs (from 10hrs encodings to fast 1 pass (http://clip2net.com/clip/m70200/1357892420-clip-10kb.png)), but result is not satisfying.

It seems YouTube doesn't care much about what is converts, it always does it's crappy convertion.

I would like to find out if it is possible to minimize the YouTube affection and if there is the good variant for game videos encoding settings on YouTube. Or it's the problem of original video - too sharp of too much action?

I think it's not action, just grass and dust all the way.

You think if I turn on some blurry postprocessing and anti-aliasing the quality on YouTube would be better?

I think video will look better if you apply blur in video editor. Not sure about anti-aliasing.
Also you can try to reduce fps or eliminate some frames (undersample rate down to 15-20 in vegas, frame decimate/duplicate or double fps conversions in avisynth). It could make video shaky, but will give more bits for every frame with for the same bitrate.

I think it's because of game settings - it gives too sharp picture. I've changed it to a little more blurry + turned on AA, so I hope it won't be so crispy.
Applying filters is not an option for me I think. Downsampling framerate too, the only reason I don't record at 60fps is that YouTube doesn't understand that speed.

Your videos look fine to me so far in YouTube's 480p (I can't watch anything higher than that on this old PC).

Yes, that's exactly the case.

YouTube always butchers videos by the same amount, but if the uploaded video is only slightly compressed and virtually free of artefacts the loss of doing another (very) lossy encoding on top of your own will be minimized.
If you're using x264 try a CRF in the range 14-18.



I wouldn't recommend skipping frames either. If you're not dopping every other frame (like 30 to 15 fps) the video will become jittery. But a frame rate as low as 15 fps will look stuttery anyway.
I'd rather watch a video that has a lot of compression artefacts than one with a low and/or jittery frame rate, especially when it comes to game footage.
