  1. I have been using YouTube-dl exclusively to download YouTube videos. I usually just go with "18" as I content with 360p. Well anyway once a week I go with best because I like to have the 720p version of a video so I either use "22" or "best". Today it didn't work for me, youtube-dl seemed to get the video but when you play the video it is all black and the sound is fine. However when I chose "18" the 360p video downloaded just perfect with picture and sound.

    Here is the video:

    I used to use video download helper to download Youtube videos but it has been months since it was able to do so. I certainly can live without the 720p version, I was just curious as to why it didn't work.

  2. for 720p (avc + aac): youtube-dl -f 136+140 https://www.youtube.com/watch?v=fdp_sp4gJjU

  3. butterw: Thank you that worked for me. However I am confused in the youtube-dl -F which lists all the video and audio parameters, when it shows the final line "22" it seems to show that it is a video and audio file both. This new way you showed me is similar to how to download from CBC where you find the audio and add it with the video and then it gets merged. I learned the CBC method from jagabo and always I put the numbers within quotations marks, I tried it with this video with and without and it worked both ways. Once again thank you and if someone knows about "22" it would seem it must be just audio now and before it seemed to be both. I know I just got the solution and I am grateful and content with that but I would like to understand it better.

  4. You are correct, there was a typo in my command.
    -f 22 gives you the low bitrate youtube 720p h264. its also "best".
    -f 136+140 gives you normal bitrate 720p h264

    I don't know why it didn't work for you the first time round.

    I thought perhaps it was because I have not upgraded by version of VLC but MPC-BC won't even play the audio and videoredo won't open the file. The "22" method or "best" method I usually use when I look at my archives would sometimes have the larger bitrates for 720p and other times the lower rates. I notice the word "string" quite often in the specs for the file that doesn't play correctly.

  6. Corrupt files do happen.

    youtube-dl -F reports the info as made available:
    140 m4a audio only tiny 131k , m4a_dash container, mp4a.40.2@128k (44100Hz), 15.50MiB
    136 mp4 1280x720 720p 1380k , avc1.4d401f, 25fps, video only, 62.77MiB
    22 mp4 1280x720 720p 656k , avc1.64001F, 25fps, mp4a.40.2@192k (44100Hz) (best)

    However it often isn't accurate with regard to actual bitrates. Here: Video is 522kbps, audio is 128kbps.
