FFdshow with H264/x264 on AVI container.

[Keiyakusha]

Obviously every file on Youtube gets reencoded with its own tools and settings. If the file you encoded locally looks good - you can do nothing about crappy quality on youtube.

Here's another video from youtube which is the best, and he says he did from FFDSHOW video encoder? so thats better then x264?.


This is what he reccomended for me..
1-
2-

so the funny thing is that this is also using H264 and x264 over FFDSHOW with AVI container.

Also keep in mind that youtube uses really low bitrates (relatively) for their content and fairly poor settings, meaning the results on fast-motion gameplay easily may not be as good as you've hoped. But it shouldn't be quite that bad if it's flagged for hd.

But basically (as you've already seemed to guess), you take the massive raw output, reencode intermediate (as transparent as you can) so you can upload it, then youtube reencodes it. Honestly at the bitrates we're talking about, you could probably use almost anything for the intermediate step. But yes, you should also change it to 30fps during intermediate.

No, ffdshow uses libx264 for H.264 encoding and the version it uses is probably not the latest. Secondly, either the defaults are bad or you guys have changed the settings to make no sense. Your first screenshots and these later ones show the same mistakes in basic ratecontrol settings, B-Frames and the loop filter. At least this other guy has set a decent bitrate for 960x540. You were using the same for twice the frame size.

x264's defaults & a suitable CRF will produce an order of magnitude better results at the same bitrate.

You haven't shown us the output that you get from x264 or even told us what it looks like, so it's hard to say if there's something seriously wrong with it. However, as people have repeatedly pointed out, the quality problem is most likely caused by Youtube's automatic encoding. Your 3-second sample clip is quite a difficult piece because there is lots of fast motion where the poor 120 fps -> 30 fps motion blur effect may cause additional problems.

So, I'd suggest fixing the motion blur (one way is to capture at a higher framerate, such as 480 fps) or try disabling it completely (drop frames or capture at 30 fps). Also, try scaling the video down to 960x540, like the other guy is doing. Youtube might handle that better.

Well then, oke here's a simple way to recognize if the quality is bad or not, fistly look at the Crosshair in the middle, and look at the writing (Kills) on the top right corner.

and as you said opening B-Frames and loop filter is allways a better option do you know what else should i use? also that image above the ffdshow one, is my friends thats how he does his settings and gets way better then mine


My test video based on X264
http://www.youtube.com/watch?v=JVLzMmLTdEs --> Jeeb showed me the preset for the X264.exe
http://www.youtube.com/watch?v=S_hMmvssX_E --> my test with different preset. from x264.exe and yes latest version

These other video which are really great, i can't imagine these videos without the re-compressed thing in youtube..

Rest of the settings don't matter that much as long as you're using a high enough bitrate (or low enough CRF) to keep the output nearly transparent. You don't need the highest compression factor for encoding YouTube-intermediates.

In my opinion, both of these videos are about as good as they can be considering the original source and YouTube's current limitations. I don't see other quality difference than editing (different contrast and color levels, perhaps different motion blur) when compared against those three other videos. Upload a longer clip to get a better idea of the overall quality.

oke then thanks for the tip ill try it out next time, a Long one with what you said exactly CRF =D thanks allot for all helping me out!!! really learned allot
