Hello All

I have just uploaded 1001 different compressed renders of my new template in progress. Render looks good before YT upload. After the YT Conversion / Compression all the lights look jagged and noisy. Tried 32bit color. Tried adding a dark Blue BG instead of Black.

Does anone know a solution for this ?

My render settings in the example here : http://www.youtube.com/watch?v=C_MX9WoG4YA

ompression: H264
Framerate: 29.75
Datarate: automatisch
Keyframes: automatic
1280 x 720
Streaming = Quickstart
Audio-Codec AAC

Thank you soooo much…getting crazy here with this:(

Try set Datarate to 10000 for example instead of automatic. And don’t use .mov files for h264. Try using native H264 option(.mp4)

It looks like pretty standard Youtube quality to me.

The jaggy edges are from the heavy Youtube round of compression and the dynamic resize.

Some things compress better than others. Graphics is renowned for showing up every compression mistake, because it’s so clean / hard-edged / contrasty in the first place… not like muddy old footage shot with a camera. :-)

Hello Felt

Yes, i know the compression Voodoo allways makes things whorst. Strange is only, that other similar videos i have on Youtube, look much better regarding the lights on black BG.

Some things just compress better than others. Maybe there’s more movement in this clip. That always foxes an interframe codec.

You could always try uploading a short excerpt that’s minimally compressed, with no visual loss. That way you can make certain that it’s not something you’re doing your end.

You could also try various tricks to fool the compressor. Apply a slight softening blur or grain.

But since it’s hard to say exactly how Youtube is compressing stuff, there’s not a lot you can do to control it.

Youtube is accepted to be rather poor quality. Consider a Vimeo account?

Thanks Felt

I solved the Problem by using (my allready existing and forgotten) Vimeo channel instead of YT :)

So the Thread can be closed.
