Sorry for the newbie question, but what is DV-AVI?

I see that this is one of the "save-as" options in MM2 to save a movie to
my computer.

What is it used for?

thx.

Uncompressed video. Best quality you can save in. Creates huge files.
DV-AVI = Digital Video - Audio Video Interleave.

When editing a project, save in this format, as it is lossless and
uncompressed. Final stage of project would be to render this file to MPEG-2
Compliant DVD.

For DV-AVI the bitrate is whatever your system can handle. It is
uncompressed video at the bitrate that the connection delivers it. You can
adjust bitrate with most video editing programs. Interlacing or
De-Interlacing is preserved in DV-AVI, depending on how you capture it. You
should visit the following site; it has tons of information...

No, No, Bobby....

DV-AVI is COMPRESSED digital video, with a bit-rate of 25 Mbps. It is
compressed by discarding half of the color information, then each frame is
compressed using an algorithm that is similar to JPEG.

Uncompressed 640x480 digital video would have a bit rate of around 211 Mbps.

Shoot, I thought I had this figured out. So what is the best quality to
save files in with MM2 that results in the least loss of quality, none
preferably.

Richard,

Sorry... I didn't mean to confuse you. Bobby's answer was correct -- DV-AVI
is the best quality format for capturing or saving a movie.

I was just pointing out that DV is compressed -- not uncompressed as he had
stated.

Sorry if this is an idiot's question. I have a Sony HDV camcorder and i want to save it to the hard disc of a Panasonic HDD/DVD recorder. On the camcorder I have HDMI out, AV out and HDV out. On the panasonic i have DV in and AV3 in. What would be the best combination to maintain the best quality - i.e. closest to HD.
Thanks, colin
