Danne, incredible workflow !
With this update, I think proxy can work as offline/online workflow editing
1) MLV/proxy => switch => clean proxy and sound with dng synched
2) edit with clean proxys for editing
3) lock edit => XML => Resolve => conform by name => online edit with synched dng
I'll try to test but that can save a lot of time and storage space

Hopefully yes. Please test and report back how it goes :).

Ok, crossfinger ;-)

@Danne, @Alex, MLV are recording fine in CF by default, but for H264 proxy, I have to select SD card again in canon menu each time I turn off/on the camera. Is there a special setting to keep it in memory ?

Ok it worked for SD/CF management by disabling the function in ML menu.

New download.

I rewrote proxy script parts. Should now match precisely since calculating ending part derived from actual amount of dng frames.

Danne, where is the option to sync proxy/sound/mlv in switch ?

No option. Automated. Just include your proxy files together with your MLV files and run Switch the normal way.
http://www.magiclantern.fm/forum/index.php?topic=15108.msg189314#msg189314

Also:
I just uploaded a new version which supports (C) changing to an alternate output folder.

Hello Danne,

I would like to replace all my old MLV workflow with Switch to speed up the process…
My concern for the moment is the White Balance, how can I manage it like in CR for example where I can tweek Temperature and Tint?
Is it possible to do this from Switch?

Second question, I use Cinelog-C (http://www.cinelogdcp.com/) to convert my MLV footages.
Is it possible to apply it directly from Switch as I don't know if it is some sort of LUT or not (the file extension is .dcp for the 5DMKIII)?

Thanks for any help on this.

S/.

Cool. Hope you´ll like it.
You can use DCP profiles on your dng files. In ACR/lightroom that is. All tags needed are provided in dng metadata.
Regarding white balance. White balance from camera is added. Then you need to refine it in your nle.
There is one way to create wb coordinates. You will need imageJ installed and then a good portion of patience as it´s about picking points on a tmp tiff file, go to next pick and save point etc. You find that workflow in (m) menu (mlv_dump at the bottom). Nice thing here is that white balance is actually transformed into actual dng AsShotNeutral numbers.
If you plan on exporting to prores from within Switch I suggest you try one of the provided logs.

Ok, I did a test with a folder containing .MLV (comp raw) + proxy with sound. I just ran switch without touching any options. It created me 5 types of files :
1) X proxy (APR LT or Proxy 36) black frames
2) X 444 (APR 444) black frames
3) APR LT or Proxy 36 no black frames no sound
4) APR 444 no black frames no sound
5) CDNG no sound
 
Is there a way to get a trimmed (no reencoding) canon H264 .mov + sound w/o blackframe ? I'd like to test it to edit offline, and then make an online edit on resolve with CDNG using MLVFS. It could be a fast and lightweight workflow.

Sounds like a good workflow

Do following:
1 - Fill a folder with proxy H.264 and MLV files
2 - Open Switch and in the first menu select (R) to reset Switch.
3 - From the same menu select (r) to run Switch

What do you get?
It should be as straight as selecting (r) from the first menu.

The proxies and the mlv files are named the same right?

I'm not getting the Wav file, I'm using the test video that you also have Danne, any idea what I could be doing wrong?

And also a request, can you make an option to leave the original footage in place to where it is and only make a output directory with the new files?

The wav file should be inside the dng folder next to your dng files.

You mean leave the original MOV alone and move the cleaned MOV to a specific proxy folder?

Yes leave footage alone and make only new output folders with new files.

For example if I have a compact flash card mounted, I can select the folder and it would not touch the files, only create new folder on my computer and save all new files to my ssd.

I could not find the Wav file in the DNG folder with the latest build ( like 25 min ago )

I'll have a look within a couple of hours.
Could you test with another file as well?

Tested and your file is working over here. Sure you didn´t run your prores file without the audio? Also check through the whole folder make sure you didn´t miss the wav file somewhere.
If you test with another file and it´s still not working I need to see the LOG.txt file.

You didn´t try another proxy file with corresponding MLV?

If still trying the same file I need to check the MOV you´re using. It still has the black frames when included with the MLV? Can you upload the exact MOV you´re using?

Could you upload it? As asked before. Are you using the prores file?(there is no audio in it)
Are you using a file that has been "cleaned" already?
I uploaded a new version for any rare occasion when there is no black frames in the beginning of a file. Probably never happwns but still...

Ok, good saw your answer. You can try this latest version and see if it works on a cleaned file.

Yes the latest version works also with the already cut files, Thanks for the update

And if you can have a look at not changing the source files directory that would be good for my usage.

I always get paranoid if my footage gets moved around and I don't know where it ends up.
this makes me do a backup first that takes more space, so I prefer it to be untouched and only create new files in subfolders / custom folder
