View Full Version : Converting a MKV file to M4V with different aspect ratios

The Dark Knight has two different aspect ratios that change depending if it's on IMAX scene or not.

The movie file is 1280x720 but if I use Handbrake to convert the file with the option to keep aspect ratio it changes to a 1280x532 file, and if I manually force it to be 1280x720 the video gets stretched out in all scenes that aren't IMAX.

Does anyone know of a solution where the file can be converted while maintaing both aspect ratios?

It seems no way. U have to keep one aspect ratio when encoding. with handbake, u also have to use its default aspect ratio

The number of aspect ratios should make no difference as regardless of which scene is displayed the frame size is still 1280x720, its just that in one scene part of that frame is black bars. I think the reason your getting the stretching is because you may have cropping turned on, this will crop out the blackbars giving you a frame size of 1280x532 and then your forcing it to stretch to 1280x720. Try forcing the output to 1280x720, turn off Anamorphic and set cropping to Custom with all the values set to 0.


UPDATE:-

Just tested and these settings work fine for me, granted my source is 1920x1080 but it should make no difference.

The key is to make sure your not trying to crop the black bars.

Thanks a lot, setting the cropping values to zero worked. :)
