Autocropping when video source is an avi file

[nine_mm]

About the autocropping feature in AutoGK...

The original avi I was working on had the following specs:

File Type: AVI
Video Codec 4CC: XVID
Video Codec Name: XviD
x:y (aspect ratio): 720x480 (1.50:1) [=3:2]
Video Bitrate: 832 kb/s
FPS (frames/sec): 25.000

Obviously missing some serious cropping, so I decided to
re-encode it with AutoGK (v 2.18b) (I know the quality suffers, but hey I am into testing).
I put a maximum allowed horizontal length of 608 pixels. I didn't touch the hidden options.
After it finished analyzing the source avi file it came up with a resolution of 608x416, in other
words the autocropping feature didn't work.

How well AutoGK can do necessary cropping when the source is an avi file?

Here is a snapshot from the original avi:

Refer FAQ 5.12 (http://forum.doom9.org/showthread.php?t=72679)
in part: "- no cropping is done for AVI mode apart from the one needed to keep AR (if you need it then enable it via hidden options)"
My (uneducated) understanding is that AR is maintained within certain tolerances, as finished resolution height/width also needs to be divisable by 16. In your stated example the AR of 3:2 has been maintained within acceptable tolerances.

What cropping were you expecting ?

if you need to crop black bars away for AVI source then you need to enable "tune auto crop parameters" in hidden options (no changes to default values are required).
