Problem with recognizing correct video size and aspect ratio

[Thunderkopf]

I have the following problem with ffmpegX: when I load a VOB file, it will oftentimes not give the correct video size of the movie. It seems that ffmpegX will give a standard size like 720 x 540 when the actual size is different, and more importantly, when the aspect ratio is different. This leads to (if not corrected) a distorted encode, where the image becomes too narrow or too wide, whatever the case may be.

I've tried finding some small application that will tell me straight up how big my video is, and what sampling is used (Pal/NTSC/NTSC film) without failing. I've also tried finding if maybe I'm doing something wrong. The way I deal with this now is quite cumbersome: I open up the movie in VLC, then take a screenshot, open the screenshot in Photoshop and look at what size the image is. Cumbersome, dumb and often somewhat inaccurate.

Can anybody help? Could the developer chime in?

Thanks in advance.

Please email to major4@mac.com with screenshots or clips.

ffmpegX should always recognize the correct source video size in the left-side LCD screens. Please note that when playing a video file, a pixel aspect ratio correction may be applied by the player and opening a screenshot in Photoshop has no meaning in respect to determining the source video size.

It is however possible that the output size (right-side LCD) is set incorrectly in some cases.

Are you running ffmpegX from an account with Adminstrative privileges? ffmpegX returned similar, incorrect results for me when running from a Normal, non-Admin account.
