General Help Q&A / FPS override audio sync problem
October 24, 2012, 09:00:16 PM
I was hesitating where to place this, since I don't know if is a bug in magic lantern or if the problem lies elsewhere.

I have been trying to record 720p at 30fps with sound record enabled (WAV).
Using Avidemux I change the video to 30fps and add the audio track. However, after less than 30 seconds the tracks are already noticeably out of sync.
I can only get them to sync decently by changing the framerate to somewhere about 30.6 fps.

Anyone else encountered this problem?
Does magic lantern not really record at exactly 29.97 fps as it states, or is it something else that causes this?

Trying out the new aperture/DOF bracketing feature that can be found in the latest Magic Lantern nightly.

I use it to shoot two consecutive pictures at different aperture - in this case f1.8 and f7.1 - and later combine them in order to get a picture with shallow DOF and yet with the subject at optimum sharpness.

Feature Requests / [DONE] Aperture bracketing
October 09, 2012, 06:21:46 PM
I would find aperture bracketing extremely useful.
I often shoot two consecutive pictures in Av mode, one with f1.8 and the next with f5.6. I later combine them, putting the sharp part of the f5.6 picture on the f1.8 one.
That way you can get images with optimum sharpness and yet with a nice soft background.
(The two pictures are of course both correctly exposed, unlike HDR bracketing)

The problem with doing it manually - that is changing the aperture using the scroll wheel, is of course both that it takes time between the shots and also that you inevitable move the camera a bit, making it more difficult to align the pictures.
