YouTube Playback Issue on Uploads

[Database Ranger]

I have uploaded several videos to YouTube that seem to be having some sort of freezing errors during playback. Sound proceeds without a problem, but there are several places where I should be seeing either a black screen or an image, and only end up seeing it for a split-second before the video jumps ahead to the next active video frame, and stays there until the audio catches up. It does not do this every time the screen should be dark or showing an image, but it happens in the same location every time.

It's a very strange error that doesn't exist in any of the files before they are uploaded, only after. The most recent video can be found here. Can anyone help me with this?

not going to watch 11 minutes of that crud. there was a black section in the first minute that looked fine. youtube says it's 11:04 long, does that match the length of the source file? if so it's just your internet connection being wacky. download the whole file from yt and watch it offline to see how it looks.

Just double-checked. The original video file is 11:09... so I lost 5 seconds somewhere.

I just downloaded the video and errors came with it. There are three freeze errors in the first 15 seconds. I have been told that not everybody sees it, though.

what was used to encode the video? and what settings? the errors were most likely in the uploaded source and yt just cut out the bad sections.

The video was edited in Adobe Premiere Pro CS4, exported as a .MOV, then encoded into a .MP4 by Handbrake using default settings (Video Codec: H.264 (x264); Framerate (FPS): Same as Source; Variable Framerate; Video Quality: Constant Quality; RF: 20).

variable framerate is always a problem, in black sections it would drop the framerate to almost 0. get rid of in in the mov and the mp4.

if possible you should skip the intermediate video and go straight from the source to mp4. cs4 can output good enough mp4 for youtube.

Hey, that's being unfair to crud

*sigh* Everyone's a critic...

Anywho, the main reason I've been using Handbrake is to reduce file size (1.5 Gb --> 127Mb). If you could suggest how to keep those file sizes lower when exporting from Premiere, then I'll happily skip Handbrake. I will also try switching from a Variable to Constant Framerate and see how that works. Thanks!

i've never been accused of being p.c.

premiere has bitrate settings for exporting mp4. you can make the output any size you want. use constant framerate and constant bitrate for both video and audio. for yt 1080 HD material i normally use at least 10mbps. lower and you might not get the yt 1080 link. 720 use 6mbps or higher.

so if you wanted yt 1080 the filesize should be ~ 600 MB

For YouTube to give a HD playback option, the video resolution should be at least 1280x720. Bit rate doesn't affect a HD option.
