Flash video dimensions on You Tube?

Good Day to you!

I was just curious does flash videos require a specific dimension for You Tube or does it resize? What if it is pixel based graphics?

What is the minimum dimensions for flash videos on You Tube?

Hey thanks for your input!

Current widescreen defaults that show up in the player:

246x240, 640x360, 853x480, 1280x720, 1920x1080

On the upload page, it says it will take anything up to HD resolutions, 2GB in size and 15 minutes in length. On the advanced upload page, up to 20GB in size, but no mention of the time length limit.

I’m assuming there’s no minimum.

And the uploader will automatically resize to the nearest appropriate resolution(s).
