YouTube video resolution
 

Are there any methods to show these videos at a larger screen size w/o a loss of resolution?

Thanks,

No, they are optimized for the viewer size.

They are all FLV encoded on the fly.

Meaning they are downsampled or in some cases upsampled from the original submission.

So what's the secret to encoding Youtube videos? Some videos on Youtube are nearly crystal clear and others look horrible. Mine aren't that great and I'm using a digital camcorder...

Thanks,

1st depends on your camera. MiniDV is the best consumer media available. How many CCD's does the camera have. What's its effective resolution. How well does it perform in low light. Any other format is either analog or compresses the video which ='s instant degradation at the source. (You won't see it though)

Then how do you dump it to your computer. Firewire and USB are digital transfers so there should be no signal loss. Anything else is analog and degredation starts at import.

Then it's your capture device, capturing uncompressed goobles disk space at ridiculous rates, here's the math a 640x480 frame is just under a mb, 30 FPS = 30 mb's for a second of uncompressed video. HD is even worse, gobbles GB's.

So most capture programs will compress on import. Compression ='s degredation. How bad depends on the CODEC used.

Then people recompress to get it to a manageable upload size, then youttube converts it to an FLV, more compression.

Video is definately consumer friendly these days if you just want to point and shoot but there is a steep learning curve if you want to go beyond the basics.
