web cam missing from youtube upload

  • Problem
  • Updated 7 years ago
I produced an HD Mp4 (720p) that includes a powerpoint full screen and a webcam headshot placed in the upper right corner of the video. It looks and plays fine in my media players, but the youtube upload only shows a gray square where the webcam image goes. I've tried a couple of different browsers. Any idea what is going on?

Hey there Bruce,

Have you tried uploading it to a different service and seeing if it displays properly?

I don't really have another service to upload it to. It's an mp4 and plays fine in Windows Media Player and VLC player.

You can upload it to Screencast.com to see if the webcam displays properly. We can than see if it's a youtube issue or another issue with the video.

I also tried uploading it as a WMV to youtube, and the same thing happens. When I download it back down from youtube, it plays fine.

It plays OK on screencast. Screen cast link is http://www.screencast.com/t/kXeriUCS7xcU, youtube link is https://www.youtube.com/watch?v=RT0P5zmHDhA   Any ideas?

It seems to be browser dependent.  Your YouTube link plays correctly for me in the Chrome browser, but not in Safari.  This is very strange.  Which browser were you using to view your video?

Yes, I was using Chrome and it worked fine.  I tried it in IE and FF and neither of those worked.

FYI, I also checked and disabled adblock on a hunch, and that was not the problem. It still fails on IE, Firefox and Safari with adblock disabled.

It works for me in Chrome, but not in Internet Explorer.  I downloaded the video (the 480p MP4 version) from YouTube and the MP4 plays correctly in Windows Media Player with the webcam completely visible in the upper right corner.  Also, in Internet Explorer, you can see that the video thumbnails were generated correctly, as shown in this screenshot: http://screencast.com/t/GTqjlHnAl7i.  These things indicate that the correct video (with webcam) was uploaded from Camtasia Studio to YouTube, but YouTube is not playing it correctly.

For some bizarre reason, YouTube appears to be applying a black mask to the left and right sides of your video.  I'd recommend right clicking over the video in YouTube and choosing "Report playback issue".

In Chrome, I'm getting an HTML5 player, whereas in Internet Explorer, YouTube is using the Flash Player.  So these are different players, which probably accounts for the difference in behavior.

This is a guess, but maybe YouTube is somehow detecting that the sides of your video are mostly black, and they're trying to "help" clean it up by masking out everything outside of the 4:3 video box inside the 16:9 frame.  Clearly, this isn't helping this video at all, as it's masking out your webcam.  But I'm wondering if you'd get different results if you moved the webcam video to be over the top of the PowerPoint recording on the canvas in Camtasia Studio.  Or, stretch the PowerPoint recording so it fills the canvas in Camtasia Studio.

Hope this helps.

I use Chrome as well as a Chrome extension called YouTube Options. When I let it use an HTML5 player (which your link's page tries to by default), I can see everything. When I tell it to try and force Flash player, the webcam portion is almost completely cropped out.

The black is actually what powerpoint creates on a widescreen playback, and I just recorded the whole screen. So I can't really stretch the ppt image, the black is actually part of the recording.

I moved the web cam image entirely on top of the ppt slide and the video is now playing corrrectly in Firefox at least (https://www.youtube.com/watch?v=ih0YP9nZxZg).

Oddly, the image moves back to the far top right into the black after the first break, at about 2:24, since I just repositioned it at the beginning of the presentation but didn't check each one of the breaks. And it continues to play fine. So that adds to the mystery.

Clearly, Google is doing something in playback, since I can download the original from Youtube and it plays fine in a viewer. So they are not manipulating the file itself, but are having issues (or are fiddling) with flash playback. So I guess this is a workaround I'll have to keep in mind.

Sure you can. Using crop and zoom (with keep aspect ratio unchecked), I was able to do just this from a youtube screen cap. Obviously the same steps would apply on your end using the widescreen with letterbox source files. Here's the example:

Or if the distorted text is bothersome and/or doesn't look as professional to you, what you can do instead is: Copy your video track to another track BELOW your video track. Position the playhead to the first frame, right click on the clip, and select extend frame. Make the duration at least as long as your video. Now go to the end of your video and chop off all the excess footage. This will give you your first frame as a persistent frame below your actual video. Now using crop and zoom (again, minus keeping aspect ratio) select a part of that frame that's all white and make it fill the screen. You'll have to also use crop in your proper video clip to eliminate the letterboxing. Here's the sample of that:

Hope that helps.
