Scan Matching
 
The XH-A1 has a lot of features I want and it's a good price, but it's missing one feature that I really want: scan matching. I'm working on a documentary that would involve shooting a computer screen and it's a perk that would really be good for the project. Can anyone recommend a prosumer camera that has scan matching? There's no way to search using scan matching as a feature.
The camera I need has to have:
- Mini-DV capability
- High Definition (HDV)
- Scan matching
- Auto focus
Go ahead and list whatever camera you can think of, even if it's more expensive than the XH-A1. Scan matching is important.
Thanks.

The XH-A1 has a clear scan function, adjustable from 50.2 to 200.3 Hz.

It's a feature that has been included on all Canon three-chip camcorders since the XL1S.

I don't know if this is the same topic or not.

I am going to buy a U.S. version camcorder (probably XH-A1) and use it in the baltic states, Russia and Europe.

Will the scan feature of the XH-A1 allow me to shoot under flourescent lights in these parts of the world and not get flicker (as well as in the U.S.)? Thanks!

(Thanks for the leap year note, Jack!)

Sorry, but what you describe is not the same thing. For that you'll need the 50i upgrade, which adds the 50i and 25F frame rates to your camera for shooting in locales such as Europe where the electrical systems are 50Hz.

I've shot regular NTSC 60i video in Europe, some under fluorescents, and didn't get any flickering problem.

If you can set the camera shutter speed to 1/100 and afford the loss of light then you won't get flicker using NTSC in Europe. Some lights flicker and some don't so you can often get away with normal shutter speeds but when it does happen you should be able to see it in the viewfinder. See Page 69 of the manual to check how to use the clearscan feature
