Re: Requesting "Full-field" Match Video for Webcasts from FIRST

Maybe in a few years it will get good enough, but until then, I'm afraid the webcasts will look a lot like this video:

IMO this video looks pretty good. Also the downloadable version is close to "TV quality". SDTV (also the quality of the signal coming out of the FRC video drops) is 720x480 because it uses non-square pixels while the video is 640x480 which is the same 4:3 aspect ratio with square pixels like a PC display. You can't really record anything better than that from the video drop.

The one difficulty is figuring out which team is which. Something like this with a zoom shot of each team's robot as they are introduced before the match would actually be quite good.

To get a good full field shot of an FRC field with distinguishable team numbers you probably need to use a wide screen aspect ratio. The dimensions of the field make it difficult to zoom in close enough with a standard def 4:3 image.
