When i upload videos to youtube they become pixelated while actual file is nice and smooth.

youtube compresses videos

its a private clip so ¯_(ツ)_/¯

to me my video looks like a blurry mess while his frames are smoother he uses srcdemo 2 i used it too strange thing is that i made one clip very smooth and and blurry no idea what was diffrent.

I think there’s multiple causes that make your video look a bit worse.

Bad color correction makes stuff a bit harder to see. Make sure you keep your levels in check (watch for over/underexposure and avoid white and black spots in your video).

You probably didn’t encode at high enough quality. Youtube re-encode’s so it’s better to give Youtube a high quality file. I’d say render at h.264 2-pass VBR with a desired bitrate of 10k with a max bitrate of 14K.

Also make sure you have enough motion blur samples and a 180 shutter speed in SrcDemo2.

Then there’s one more thing. Choppy demo playback. Try and play back your demo in slow motion (host_timescale 0.5 or 0.2), and see if the player models and their position jitter a lot. Some demo files and some pc configurations seem to suffer choppy demo playback a lot more than others.

What happens when your demo is choppy and you use motion blur: the frame samples used for the blurring aren’t postional/time consistent with every “actual” (newest) frame, which creates an aura of blurriness around everything.

So to summarize:

– Fix your colors/levels
– Encode at high quality. Use 2-pass encoding.
– Make sure your blur/frameblend settings are optimal.
– Check if your demo playback is choppy/jittery and if it is, try to fix it (I have no idea how, my demos are always terribly choppy and I have never been able to fix it)
