    I have uploaded my New Year's Eve video to Youtube. The file uploaded is 43000 Kbps WMA video in 1280x720 50p. I set the bitrate so high, because I noticed the WMA format needs somewhat higher value than an MP4 h.264 to avoid loosing quality. It plays flawlessly on my HP620 laptop, even in full screen, but when I upload it to Youtube, the video doesn't play continuously from there on my laptop. It doesn't even play fine on my mother's Lenovo laptop. There are a lot of jumps during playback. However on the iPad 4 they play fine from Youtube. All computers use the same Wifi connection here. I tired to upload the video converting it to MP4 h.264 in 11000 Kbps, but it didn't give much better results, but the quality was much more blurry. How could I improve the video to play without jumps on the laptop, like it plays in my iPad? The blurriness is acceptable in case of the WMA, but that would also benefit an improvement when uploaded to Youtube.

    Here is the youtube video:

    Here is the original WMA (on fast download server):

  2. YouTube sends different versions to different devices which in turn buffer differently. It's almost surely a network throughput issue either at your end or YouTube's. Is the playline grey all the way across? What happens if you play the jumpy version a second time? Is it smooth then?

    For second time it is smoother, but the overally it looks as if it would be a 15fps video. It is like that on every laptop here. I recorded the video with a Samsung S10 camcorder, but when I upload it to Youtube, it looks as if it was recorded with a poor mobile phone, like my 8 years old Motorola. The iPad is connected to the same Wifi network, that is streaming this video very well, interestingly.

    Also, the video is available in HTML5 or Flash. I always get some stuttering in HTML5 on my PC.
    When I switched to Flash, it looked pretty smooth.

    You can opt-out of HTML5 and default to Flash by going to youtube.com/html5

    For me it starts playing it smoothly when I switch to HTML5 player. )))

    What the hell is going on here???? I guess that's why the iPad played it fine.
