#9 Aspect ratio not obeyed when it does not match display size

[Chris Pepper]

First, the Advanced button in the toolbar is dim. Is there a way to enable it, or is it not active yet?

Second, I have several video files downloaded from my TiVo S2. They're 480*480 with an embedded aspect ratio specification of 4:3. When I convert them with VisualHub & Optimize for: Apple TV, I get appropriately rectangular content: 720*540(?), but VideoMonkey gives me 720*720 for Apple TV (or 480 if I limit output to input).

1. VM should honor the specified aspect ratio. This probably means expanding out the horizontal pixels by 1/3 to 640, to avoid synthesizing pointless pixels.

2. VM should let the user specify a particular resolution, presumably under Advanced.

Thanks for VideoMonkey!

I updated the summary to reflect the bad aspect ratio bug, and opened a new RFE to implement an advanced panel

Please run mediainfo on the file in question and add the output to the bug, so I can see all the parameters of the file. To do that, (assuming VideoMonkey is installed in /Applications) type this at a Terminal prompt:

/Applications/VideoMonkey/Contents/Resources/bin/mediainfo <filename>

I downloaded SouthPark.mpeg from the TiVo. SouthPark.AppleTV.mp4 was produced by VideoMonkey.

Hmmm, the output you sent shows that the file VM produced is 640x480, which seems like the correct result. Are you saying that the result is actually 480x480? I will try doing a similar encoding and see what results I get

[Chris Pepper]

You're right. That was a reconversion via VisualHub. I just converted the .mpeg file with VideoMonkey again:
