WinFF presets producing some strange results

[tors10]

I'm converting a 400x300 .flv to mpeg4 h.264 and am getting some strange behavior from the WinFF presets. On the video tab, I set size to 720x480 and aspect ratio to 4:3. (WinFF version 1.4.2)

The -crf 15.0 preset works as it's supposed to...

but the -crf 35.0 preset produced a video without the specified 4:3 aspect ratio. I've checked the properties in Media Player Classic and the aspect ratio info is missing.

I also created my own preset by changing the -crf number to 25.0, leaving all other parameters the same. It produces a file with audio, but the video is a black screen, and the aspect ratio is incorrect here as well. BTW, if I change size to 640x480 the aspect ratio of course looks correct but "4:3" doesn't show in properties and the video is still blank

Why is the -crf 15.0 preset producing the video with the specified settings but the other presets aren't?

Can you post the full ffmpeg command line?

You could also try another ffmpeg frontend like hybrid or xmedia recode.

These are the 3 command lines. But I'm adding resolution and aspect ratio in the video tab.
