not an accurate assessment because youtube transcodes your video to a crappier codec before showing it

[GranulatedThingy]

this scenerio reminds me of adverts you see on the telly for other televisions !

@IAMNOTINFECTED The moving gradients just represents any soft color you would have in a movie. Everything in the movie other than edges will look like this if encoded in the same quality..

[IAMNOTINFECTED]

So what would be a good codec to use if you have a video with moving gradients? Help much appreciated :-)

FLV is a stream format but FLV1 is the format Youtube uses! Youtube doesn't use VP6! FLV1 is modified MPEG4 with another Stream-Syntax. Some smart FLV1->DIVX vonderter simply translate the streamformat to DIVX, wich is much faster and it has no quality loss. UNHUFFMANIZE -> TRANSLATE -> HUFFMANIZE Finish!

FLV is a stream format not a codec. Also VP6 (the codec YouTube uses) has nothing to do with MPEG-4... and it's developed by On2, not Macromedia or Adobe.

Get a clue!

nice....hey resuorce of research papers at "media_h264" google search

[flipflopsneeded]

so true...

[Shashkoila]

You lost.

PS: But FLV1 is VERYFAST to encode and decode, which is a good goal on server-automated transcoding -> it saves CPU-Time on the servers...

[BloodySword1987]

The codec youtube is using is FLV1, it is a modifyed type of crappy MPEG-4 developed by Macromedia or Adobe. The Qulity is comparable to the old and very crappy MS-MPEG-4 V1 codec... Bad quality on high and low bitrates, too...
