If anyone is interested, I just had a bash script put together for raw2dngOSX to automate the DNG extraction process. Read more and download here.

Personally, I've been using this, then Adobe Bridge's ACR and "Export to Hard Drive" function to create a JPG image sequence which I bring into compressor to create ProRes files. Not the most elegant workflow, but it's the best looking finished product I've been able to muster. As much as I love the speed of the Cineform workflow, I just can't bring myself to use it's terribly soft debayering. It's just so bad.

Hi, why for example in Photoshop they indicates only 8 bits
I know is 8,16,32 bits per channel so which software can tell us a
project is a 14 bits raw

you would have to process the files at 16 bit (or 32bit) in order to make use of all the raw data ..

There is no 12 or 14 bit setting, and if you set it to 8bit you loose a good amount of detail

At the bottom of my photoshop screen, it shows "8-bit" right?  It's a blue clickable link.  Change it to 16.  Then you output 16 bit tiffs 2x larger.  I did a visual inspection and I didn't see the difference between these which is a surprise.  I didn't take a file with subtle gradations like a sunset sky however and I know final grading that I would do thereafter would be more noticeable.

Having an issue, anyone else had this happen?
I go from .RAW file to raw2dng(even 0.9)
DNG's into photoshop ACR
Export out of ACR to 16 bit .TIF files
Open image sequence in 'quicktime 7 pro'
now heres where the problem occurs. When I export out of QT7 as ProRes 422 or lower quality, it's perfectly fine.
But when I try and export as 4444, the video seems to be blank. All of the other exports have a thumbnail, my 4444 exports have a black thumbnail and when opening in VLC, it won't open.
I've converted to 4444 many nightly builds and raw2dng's ago, a couple of times. Now, Im not sure whats going on.

probably codec issue. Vlc doesn,t play prores but premiere import the files just fine. Also viewable in quicktime. ProRes is mainly for editing I believe.

Hi! Has anybody come up with a workflow synching recorded audio together with the separated .raw moviefiles? Trying in premiere but I still can,t get the audio to synch. I,m at this build Magic Lantern May 29th(5419e04).
I tried setting fps to 24 manually and also through the canon menu but no luck. It drifts.

I keep on getting this "Error: This ain't a lv_rec RAW file" error.
The footage was shot in a normal way. Any way to recover what's inside the .raw files? Mac.

A tip for OSX: I wrote to Apple about Apple Compressor because doesn´t recognize image sequences and original sizes. The solution when import image sequence was very easy: delete de first frame, because Compressor doesn´t recognize 00000.

For MAC USERS, you can import all the footage, from different shots, and export in the format that you want: pro res 4444, 442, uncompressed, resizes, etc. And Compressor use optical flow to get the file, that means better quality.

Las comment for Quicktime users: I don´t know why Quick Time 7 change de color that you work in ACR. That´s why you must color correct again the footage. In this case Compressor doesn´t have this problem.

Thanks!

Having the same issues... Searched a lot but with no success. JPEG's are ok, but TIFF won't work (QuickTime Error -50, on compressor).

Tell us what they replied, it should be able to work.

I'm using Compressor 4.0.7

Don't be lazy, read the entire topic, it's just 8 pages long.

Split the raw files by raw2dng, a program they made to split those files in GUI, so casual users could split them without touching terminal. just search, there's a topic just for the program and i guess it's linked here.

Then use a raw manager to process the files and create tiff's or jpeg's and then put them together with your codec of preference.

The step by step guides are already all here, you just have to do your homework and search it.

a) try with this http://mac.softpedia.com/get/System-Utilities/Compressor-Repair.shtml   If not...
b) reinstall compressor... if not
c) you have Quicktime problems, different version and you have to choose 7 or X.

Tried it all, i'm only using quicktime X now. I'll try quicktime 7 without correction, see if i get a clean copy, but would be nice to make this by compressor 4, get my workflow easier.

I don't know the details of mac, but you should first read the standard thread to generate DNG in mac environment.

Quick and dirty, Import each RAW set of DNGs into Adobe After Effects (and change exposure, colour, highlights, shadows, etc...), then 'interpret' the footage as whatever frame rate it was recorded as and save setting using 'remember interpret' and apply it to all your clips, make a composition file and change the file duration roughly calculated to the total length of all your clips (you can always extend/reduce by editing the composition later), then select all clips and drop them into the composition - space them out - and render the composition out to lossless. Bring the rendered output file into an NLE for further editing.
