The problem is that the uploaded video is 1:31 long and playback is broken. I encoded the video using the latest Handbrake with the "optimize for streaming" box checked.

Does anyone have a clue what's wrong?

Thank you!

PS: http://www.youtube.com/user/waterfordinst#p/a/u/0/EQfIJgtviK0 if it helps!

Try using "mkv" as the container, people have reported that container to work better in conjunction with youtube.

[lucassp]

After many many hours of trying to upload the mkv file, I finally succeeded. The YouTube video now has 3 seconds:mad: I converted from mp4 to mkv using mkvtoolnix.

Did you deactivate header removal compression in mkvmerge GUI? I don't know whether youtube supports it or not. Go into options and tick "Disable header removal compression for audio and video tracks by default". Then restart mkvmerge GUI and mux the file again.

[lucassp]

Another difference I spotted between the mp4file and the mkv file:
MP4
Frame Rate........................................29.970 fps
Total Frames......................................118579

MKV
Frame Rate........................................30.000 fps
Total Frames......................................118673

[sneaker_ger]

You can force "30000/1001" as the fps in the track tab of mkvmerge GUI if you think that it's wrong. But it simply copies the timecodes of the source file so sync should be OK either way.

But the number of frames shouldn't change IMHO. Something's wrong.

[lucassp]

Checking that boxed worked. The video was encoded by YouTube. But now there's a delay between the video and audio...It seems like progressive delay. But if just go the minute ±40 the delay is smaller. It's driving me crazy!

http://www.youtube.com/watch?v=BbxnA3L-5SQ

Thanks!

PS: The delay was introduced by forcing 30000/1001. I will upload again :(

[sneaker_ger]

Yes, normally you don't have to touch the fps as mkvmerge just copies the timecodes from the mp4 file.

[PhrostByte]

I've had Youtube problems with x264 encodes too. I eventually just started encoding to Baseline profile which seemed to solve everything, though it would be nice to find out exactly what setting is triggering it.

[lucassp]

If the YouTube Advanced Uploader would be more stable I wouldn't have bothered to encode the video with these aggressive settings. But since the Advanced Uploader was crashing a lot, and my video file was 1h5min, I had to make it a lot smaller.

I have problems uploading a video (1920x1080) too, it was encoded with "x264 --preset veryslow --crf 8" and flac audio, muxed to mkv. First uploading worked, but playing the video on youtube was not possible, I could see just a a few frames after seeking and no audio at all. Thought it could be the header compression feature in mkv, deactivated it and uploaded again -> Unable to convert video.
What options are needed to get a youtube compatible video out of x264?

[ganymede]

I've had Youtube problems with x264 encodes too. I eventually just started encoding to Baseline profile which seemed to solve everything, though it would be nice to find out exactly what setting is triggering it.I tried different settings with '--profile high', but youtube was unable to encode video produced like this, or sometimes to display it (video was reported as "processed" but youtube displayed only solid grey).
Finally, it worked for me with '--profile main --level 3.0 --weightp 0 --crf 18 --tune film --preset veryslow' on a 848x480 progressive clip, in an mp4 container.

[sneaker_ger]

I went out of my way to test it myself, encoded a 1920x1080 video with x264 1924 (--preset veryslow --crf 8 --fps 24000/1001), encoded the audio using eac3to to flac and muxed with mkvmerge 4.6.0 (header compression disabled) - the video plays perfectly on youtube.

It does not work. I tested also with 16bit/48khz flac, no difference.

[sneaker_ger]

Are you sure header compression is turned off?
You have to untick the option before opening a file in mkvmerge GUI for it to work, not after. You can check with mkvinfo (or newer versions of media info).

The only other difference I could think of is the framerate. I already forced a constant framerate with x264, so try --fps 25 or --fps 24000/1001, to see if that could be the source of the problem. Or maybe youtube is just very picky.

[xv]

I selected "Compression: none" for all tracks, isn´t that the correct option? I also tried old mkvtoolnix (2.9.5), doesn´t work either. Without selecting "Compression: none", Youtube accepts the file, but conversion won´t work correctly. Framerate is constant at 25, but I didn´t set any option in x264. Is the framerate stored in a H.264 header somewhere?

[sneaker_ger]

I selected "Compression: none" for all tracks, isn´t that the correct option?

Yes, that's the correct option. You can tick "Disable header removal compression for audio and video tracks by default" in mkvmerge GUI's options if you don't want to set that manually for every file and every track.

It should be stored somewhere in the headers, but I don't know the technical details myself.
I will attempt to upload a 25 fps file without forced fps - currently encoding.

[sneaker_ger]

Ok, youtube finished converting: the 25 fps file (without forcing fps) also works. I don't know what's wrong with yours.

[xv]

Maybe the overall bitrate is too high? Problems with some tags (Colorspace, Language)? Am I just too stupid?
I upload the video file (Advanced or Standard uploader don´t matter), then it says Processing... , Processing completed and nothing happens (no preview pictures). When open "My Videos" it says "Could not convert video".

[ganymede]

I tried several variations of High@L5.1, with differents CRF / bitrates, different audio formats (AAC and flac), different containers (mkv, mp4)... It worked once with a small sample (less than 10 seconds, with flac audio in an mkv container) but never with a "real" clip (5min 55s), even with the same settings that worked for the sample... :confused: Youtube is either unable to process it, or unable to display it. I'll have to stick to Main@L3.0 without weighted prediction. :(

EDIT : I had better success with --profile main --level 3.1 --weightp 1, on my 5min 55s clip.

[xv]

I just saw YouTube supports up to 20GB files with "Advanced uploader", so I´m now creating a lossless H.264 file, hopefully file is not getting bigger.
I´ve tested with a 5 seconds sample and it worked. I uploaded H.264 lossless before, but not HD or just static content, never a file >1GB.
Funny thing is that YouTube does not reject the file with header compression enabled, it just can´t process it correctly. Maybe there is something in the header YouTube doesn´t like that it cannot see with header compression...

[sneaker_ger]

For the record: I'm didn't use any "advanced uploader", just the web site.

[xv]

I´ve tried both, could not find any difference in supported formats. It´s just the way the files are transferred to YouTube (AJAX vs. Java). You can use advanced uploader directly within the website, it´s just a java applet. The only visible difference is the file selection dialog.

Edit:
I finished encoding the hole video again and I´m now uploading it. I can already see the preview frames, so I´m confident that it´s working this time. Command-line used (not very special):

x264-992 -q 0 --colorprim bt709 --transfer bt709 --colormatrix bt709

(It´s x264 rev. 992, the last one with now deprecated lossless mode). Audio is FLAC 24Bit/96kHz, muxed to mkv without header compression.

Edit 2:
Video is uploaded and works perfectly. Also the lossless file is less than 3 times bigger than the --crf 8 file! If you want to upload a high quality video there is no reason not to use lossless (except you care that uploading will take 3 times longer)
