I would recomend ffdshow encode (lossless huffyuv is perfect for realtime video capture, also ffmpeg own codec ffv1 http://en.wikipedia.org/wiki/FFV1 can be selected in ffdshow).
Later this can be encoded with padding to 1280x720 with help of the ffmpeg.

Code:
@set x264opts="level=4:qp=16:ipratio=2:colorprim=bt470bg:transfer=bt470bg:colormatrix=bt470bg:fullrange=off:overscan=show:pic-struct:force-cfr=1:aud=1:threads=auto"
@ffmpeg -i %1 -c:v libx264 -preset ultrafast -tune zerolatency -profile:v high -x264opts %x264opts% -x264-params %x264opts% -vf "pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=sar=1/1" -af "aresample=resampler=soxr:osr=44100:cutoff=0.95" -strict experimental -c:a aac -b:a 320k -ac 2 -shortest -movflags faststart %1_.mp4
@pause

Youtube think I'm bot and I can not pass verification as I have no phone which is required. Now it's not possible for me to upload videos longer than 15 minutes.

Technically 60fps should be the up most limit, so just upload a movie in 50 and it will be 50fps, just like now with 30fps you can use 10 or 15 or 20fps if you want to.

Definitely looks like it is more than 30 fps in Firefox here. When it is on low quality, like 480p, it is 30 fps, but if you set it to 720p or higher then it becomes more fluid.

I thought you are kidding but there is really a "Stats for nerds" menu item.


I tried one of my uploads and was just wondering...

timestamp seconds 34.863
640x360, 750136 average kbps, 23% volume
TagStreamPlayer, HTTPS/DASH/VOD, 13107 kbps
24 stage fps, 0 video fps, 113 dropped, 0 kbps
software video rendering, accelerated video decoding
-24.669 db, 1 audio factor

...what is "stage fps" and why is it jumping from 10 to 24 and why does it say "software video rendering" when HW-decoding is ticked in the settings? Why does the stupid YT player not render to a HW-overlay as any other player?

The thing that nags me most is that the clip looks smooth as silk on my PC and after the upload - well - just take a look: [ Show youtube player ]

Dunno about "stage fps", some kind of key frames maybe, the next value is the most important one - "video fps" - it's the actual number of frames in the movie that youtube displays, for me it's 30 no matter what.

I doubt that YT would convert all of the "old" movies to more-than-30fps even if the source file is more-than-30fps, but I'm talking about the "new" movies shown as the example above that are suppose to be 60fps already.

Once YT will fix this you'll probably have to reupload all of your movies to match the sourcefile fps, but I dunno, tl;dr...

I was thinking the same thing, for the majority of youtube users this won't be an issue, most won't even notice. But when you're uploading videos that require exacting frame rates it's a pain in the ass! Wishful thinking that youtube will convert older uploads to their native fps, I guess time will tell.

I doubt that this is even possible,except the keep the source material ,in a huge archive forever, after they have converted it to 30fps YT standard.

Hmmm it's big bad google who's behind YT,so maybe they do......

EDIT: can someone with fast internet connection and a 4k screen confirm that even 4k videos have only 30fps on yt?

YouTube (Google) change the menu every so often. Up until the end of last year there was a really useful "stop download" option, which I used whenever I wanted to stop a download immediately - sometimes I would accidentally start watch a video I had already seen, or needed my bandwidth for something else and didn't have time to waste.
Now I'm forced to close that particular browser window/tab to stop a video from downloading.

Have you seen the internal server error message about monkeys when errors happen on YouTube? That's one of the few last remaining bits left over from the original founders (back in 2005) of the site. Yes, YouTube will be 10 years old next year, and I have been a member since 2007.

I guess stage fps is something to do with the video being split into multiple segments (part of DASH/VOD format, as I recall). Each 'stage' (segment) has different rendering fps??



My stats whilst watching the latest video from Hannah Hart (MyHarto) - MY DRUNK KITCHEN (feat. Miranda Sings) [ Show youtube player ]:


timestamp seconds 26.679
256x144, 241890 average kbps, 100% volume
TagStreamPlayer, HHTPS/DASH/VOD, 360 kbps
10 stage fps, 16 video fps, 23 dropped, 0 kbps
software video rendering, null video decoding
NaN db, 1 audio factor


FYI: My browser is Firefox 3.6.22, OS is Windows 2K SP 4, Flash Player 10, laptop is Dell Lattitude C610 powered by a Pentium 3m CPU with a 460.8Kbps (3G) internet connection and I watch YouTube videos at their (current) size as displayed on the videopage - I don't watch video's fullscreen, as it causes it to (re)download the video from a larger file source (in the old days, fullscreen videos used the same source data stretched to fill the screen - not particularly noticeable with SD vids on a 1024x768 screen).

Gamersyde. The original video (best quality) can also be downloaded..

Guys, YT videos can be downloaded locally thus even if player in browser not support 50fps then anyway video can be played locally with 50fps.

Sure, it is possible to download videos for viewing (and storing) locally, but the whole point of YouTube is to enable lots of people to view your video the way you made it (e.g. at a specific FPS or screen resolution etc.). It is not designed to be a file sharing site.

yes but trust me - watching 50fps video on 60 fps screen is still far from perfect thus for preview 30fps capable browser seem to be sufficient, if nature of video is demanding i.e.it is 50fps then still it can be downloaded and moved to external player connected to 50fps display (unless your PC is connected to TV).

So YT can *FINALLY* do 60fps...

http://kotaku.com/youtube-finally-su...ome-1652460542

Even though the Chrome-fanboy who wrote the article mentions Chrome only, I tried it on IE11 and FF33, and in HTML5 player mode both show beautifully smooth animation.

https://i.imgur.com/10IKdma.jpg

EDIT: Woops, looks like I was sleepy and wishful thinking last night. No, it doesn't work on FF...yet, I hope.

EDIT 2: Got it working in Firefox 36 using this http://www.ghacks.net/2014/07/25/ena...fox-right-now/
