How can I record Xbox 360 gameplay without a camcorder or capture card?

Q. I've heard you could do something like that. I can't use my camcorder because I basically lost all of the cords for it ( Meaning I can't use RCA cables) If there is anyway, please tell me.

A. here are the guides of how to do so without using these devices...

Good luck!


How do I figure out the lens distortion on my Canon HD camcorder?
Q. I recently got a new Canon Vixia HF R10 HD camcorder. I do a lot of visual effects work and Id like to use some new footage I shot. I need to know what the radial lens distortion of this camera is, but I'm not sure how to find it.
Secondly, whats the best way to convert the footage from my camcorder? The raw clips from the camcorder are .MTS files, which I'm having a hard time opening.
Any tips or ideas?

A. Hi "UFO":

The best way for you to determine the lens distortion is the "empirical method": just shoot some test charts at different zoom & distance settings. Either talk-along with your test footage, noting the zoom point, etc., or "slate" each setting with a note card & dark marker.

Both grid and concentric circle charts will tell you how much radial distortion the lens contributes. Read up on the topic with either a Yahoo!Search or the excellent Wikipedia article: http://en.wikipedia.org/wiki/Distortion_(optics)

If you can't buy or generate your own good reference charts, go to a fabric store and buy some cross-hatch/plaid (thin grid lines) and some perfect circle patterned fabrics (use the Wikipedia article pictures as a guide) or some paper archery targets. Just be careful when using fabric, so you don't introduce distortions by stretching the cloth.

As for camcorder footage conversion, depending on what editing software you have, the best conversion is NO conversion. You should always edit using the native camera format, since any time you convert compressed (MPEG4, and up-converted at that) video you are losing quality.

If you post what software packages you have for editing, using the "Additional Details" link, I can give you better file import/conversion tips.

hope this helps,
