Higher Resolution Youtube Videos

[Gapz]

I personally tested this on some videos, seems to work on a few but alot of them seem to have the same quality, worked perfectly in the Virts "Style" Video,

Odds are about 1 in about 10 videos will have the higher resolution available from just me selecting random videos and testing

Higher Resolutions or not, YouTube still tweaks the quality of its videos for users depending on what kind of connection they've got. So how about a workaround to make sure you're getting the best of the best? Bayme of the VideoHelp.com forums seems to have found a way to tweak the URL of some videos to force YouTube to serve you the version with the highest resolution. The good news? It's easy as pie. The bad news? It's not going to work on all your videos, and it's not noticeably better
To give it a spin, just drop &fmt=6 at the end of the URL of any video you're watching. If YouTube has a higher quality version available on its servers, it'll start playing right away. Otherwise, you'll simply be staring at a loading symbol. Greasemonkey users can also download a simple script that adjusts all YouTube URLs automatically.
There's a long discussion over on the VideoHelp boards about which file types are retaining the most quality after automatic conversion. YouTube appears to be experimenting with a few variants of Flash and H.264, the latter of which became a major part of YouTube with the introduction of the iPhone and AppleTV--both of which access videos from the service without using Adobe's Flash player.
