Letterboxing video for youtube

[cwy]

Youtube now lets you view video clips at high quality (if available) - below the video screen, click on "watch in hq" to see it in hq. But in order for a clip to be viewable at HQ, it has to be in 4:3 aspect ratio. If a clip is widescreen, it has to be letterboxed (black bars on top and bottom). Can someone suggest a tool that letterboxes a widescreen clip? AutoGK doesn't do it. Even if I use a letterboxed clip for the input, AutoGK still UNletterboxes it (removes the black bars).

And of course, if anyone has figured out a way to upload widescreen clip in 16:9 AR (without black bars) to youtube and make it viewable in HQ so I don't have to add the black bars, let me know. Yes, I know that adding &fmt=18 to the URL will show the clip in HQ, but that's not convenient. I want the "watch in HQ" link below the video screen.

For example, this is a clip with the link "watch in hq": http://www.youtube.com/watch?v=y1TURJ7QQd0. The original clip is letterboxed (I uploaded this clip myself).

This is a clip without the "watch in hq" link after a non-letterboxed file was uploaded: http://www.youtube.com/watch?v=WjqGvtWlrDQ. It can only be seen in HQ by adding &fmt=18 to the URL: http://www.youtube.com/watch?v=WjqGvtWlrDQ&fmt=18.

I'm not sure what kind of a clip you're referring to, but you can disable the AutoGK autocrop function in the Hidden Options (CTRL-F9):

To completely disable auto crop you can set threshold to 0.

What video format?

The source is mpeg. Any suggestion for letterboxing a widescreen clip?

The AddBorders command in AviSynth:

You can do the same thing in VDub(Mod) with the Resize Filter and the "Expand Frame And Letterbox Image" box checked.
