Viddler produces some of the highest quality web video I've seen. More importantly, they don't resize your video as you're uploading it so it's perfect for screencasts. It's a shame, then, that their default embed code has static hardcoded dimensions instead of the actual dimensions of your video which means that your video gets scaled and appears to be of a lower quality than it actually is.

Fixing this is trivial.
Simply edit the embed code and change the width property to the actual width of your video. For the height property, you have to add 42 pixels (the height of the control bar at the bottom of the video) to the height of your video.
That's it! Embed your video using the new dimensions and it will play back at its native size and look gorgeous.

tenk youuuu
Nice find Aral. Though we do resize some videos (if they are very, very large resolution) so that text appears much better when the video is playing at the default or most commonly embedded sizes.
Thanks for using Viddler and we’re glad you’re enjoying your experience.
