Hi

Im going slightly mad trying to figure this out. What I want to do is:

Get a 16:9 avi-file cropped at the sides and then encoded (possibly with slight distortion depending on how much Ive cropped) to entirerly fill the Touch's screen without zooming. In other words, on the ipod, there would be no zoom-mode at all. My reason for doing this is that I feel like Im losing the sharpness of the video when zooming. Encoding the high resolution source material with "fixed zoom" would solve this. I could also live with a small amount of stretched aspect not to miss too much of the sides.

My attempts so far has included adding a certain amount of crop (20-50px per side), setting height, width and output resolution to 480x320 (aspect can only be set to auto, my guess right now is that this is the culprit).

This produces a file that is 480x320 according to VLC (and also looks the same in Nero). BUT, when adding this fscking file to iTunes, it reports it being 573x320 or something like that (can check on this when I get home) and the Touch displays it the same way with letterboxing.. aaahh going mad!.. Has anyone achieved this? Any help GREATLY appreciated!

Yiiihaa, finally!

As I suspected, aspect ratio being locked at "original" was the culprit. When I cropped the video (which should/could automatically result in a new aspect ratio in the converter) videora keeps the original aspect ratio 1.77. The solution was simply to override videoras setting using the CLI-parameter "-aspect". Now I encode my 1.77 videos to a 1.6 (yes thats right, not the ipod touch's 1.5 ratio - im keeping a tiny black bar at the top and bottom) by cropping the necessary amount and setting "-aspect 1.6" in the CLI field. (Almost) full screen videos with crystal clear quality (other settings I use are 768kbps 2-pass/2-pass).

One more try to get this posted...

I've solved this problem with simply adding -aspect 1.6 (or whatever aspect you want) to the CLI-parameters and adjusting the cropping acordingly not to stretch the picture.
