Why would this make any sense?
We are saving raw. Do in post whatever you like to do.

Why does Red do?

g3gg0

like said: as we are saving raw, it doesnt make sense.
do this in post processing please.

if you are an end user, wait until we looked over it. then we are going to implement some example code
to write and read this file format. and 1-2 months later it *may* be in the ML sources.

Yeah that dodgy g3gg0 is always making OP's with incorrect facts  :o

It just seemed worded funny I don't know. I wanted to make sure. I was wondering if there is an update to this eta, that's all.

g3gg0

there is no hard schedule for this. it will be implemented when there is some spare time ;)

Update: (see first post)

The first implementation is done and we can record in the new format.
post processing is still done with 'raw2dng' after converting the .mlv into the legacy .raw format using mlv_dump.
(you have to compile it yourself on your computer)

see the short video i made: http://www.youtube.com/watch?v=A6pug1g-kNs
it shows a bunch of the new (user visible) features of that file format.

if you want to test recording, grab my sources from https://bitbucket.org/g3gg0/magic-lantern or use the pre-built ones. (5D3)
use it on your own risk.


if you can show the mlv_dump logs of your cameras, it would help me a bit.

Can i just drop the contents of raw_rec.zip in the "modules" folder?
This way i can't initialize any module.

Adding the pre-built modules does not work on the 50D (error linking modules). I think the problem is with the IME modules. I get compiler errors with ime_base.
