Dailymotion uses 6000 kbit for 1080p. Youtube 4000 kbit (at 30fps - but only if the video complexity is enough. A tutorial video for example will never get 4000. My NFS 1 videos often only get half of the bitrate)
Dailymotion though uses always 6000 kbit. And they even encode 2pass ! with x264 preset slow !! Of course that has by far better quality than youtubes rather very fast encoding settings and 1 passed bitrate limitation and even combined with a high CRF or with whatever method they imply the complexity within the max bitrate. |

By selecting 2160p VP9 60fps, I have a lot of dropped frames due to slow decoding in window and full screen mode. Chrome needs to update the VP9 decoding engine. Quote:
I didn't find a choice of full video+audio stream. I don't want to download audio and video separately and merge them afterwards. Using MPC-HC x64 latest nightly (LAV internal), I decoded the clip in 4K VP9 60fps easily with <50% CPU utilization.

I meant using IDM or other similar apps to download clips from Youtube, you get the muxed video+audio file.

Oh, so 1440p and 2160p 60fps VP9 do exist? That might explain what was stated on the CompleteYouTubeSaver MantisHub page on the 31st about "new 60fps formats"...
And guys, about VP9 and audio, MPC-HC has the ability to play MKV and WebM video files with external audio files as long as they have the same filename (other than extension). Since the VP9 and Vorbis DASH streams (no idea about Opus) are already natively in matroska/webm, you don't need to repackage them or anything other than using different file extension (for example, WebM audio is technically .MKA since even foobar2000 can play taht back, and foobar is very picky about file extensions matching their format).

Well, I guess you have to wait for other programs to be updated with these formats. Last edited by mzso; 3rd February 2015 at 13:37. |

Use either the latest trunck builds of LAVfilters or use the latest 64bit MPC-HC. I know with the latter I can do 1080p 60fps VP9 on even a 2.4GHz Core 2 Duo without any dropped frames (but with like 95% CPU utilization )
Note however that if you have a CPU without SSSE3 (not SSE3), you may have performance issues (I have not yet tested the latest trunk 32bit LAVfilters on a CPU without SSSE3). Last edited by Nintendo Maniac 64; 4th February 2015 at 00:26. |

Potplayer 32 with LAV from here is not near as fast. Can't play it full speed. I get about 90% cpu usage and framedrops. |

There is no need for PotPlayer to use other filters/decoders than its own.
Using latest PotPlayer x64 with internal decoders for 2160p60 fps VP9 file, I see the same CPU utilisation like MPC-HC x64 with LAV internal.

All decoders have issues now and then.
Which video processing filter ?

Also some internal decoders produced garbled output or subpar performance, but you can't disable them. |
