DUAL ISO VIDEO MODE PROBLEM
« on: February 01, 2016, 02:36:37 PM »
Hi there , im trying to shoot Video in Dual Iso mode. Im a windows User and i read this guide (Tutorial - Guide to using Dual ISO Mode on your Canon 5D Mark III) which was suggested in this thread (Dual ISO - massive dynamic range improvement (dual_iso.mo) ).

While in the post it suggests to extract the DNGs and then use CR2HDR ( thing that i have done but then it doesnt read the files into adobe premiere pro cc ) , in the guide mentioned above it says to use avisynth to split all the A frames to the B frames to create a C frames with obviously no lines. The guide talks about Main.cmq command etc so i think it is written for Mac users and seems to be very simple so i think that i'm complicating things that should be simpler.

So the question is : Which of the 2 ways should i use to get to edit my dual iso videos?
Than: if i should use Avisynth , how can i use it on windows easily? ( it talk about opening a text file and adding command lines which seems to be too complicated to me)

Thank you for your support

Avisynth? Are you mixing things up with HDR post workflow?

The workflow in the tutorial uses HDR + Dual-ISO and Avisync is used to handle the HDR part. You are not using the HDR option so I suggest not using this workflow.

ok guys thank you very much ,
so then in i got a video recorded with the dual iso option what should i do to edit it on premiere like any other dng file?
I do not understand the reason why if i get the raw file and after i extract all the DNGs once i process them in CR2HDR adobe premiere doesn't read the file and gives me a line of error .

You'll have to ask Adobe why they aren't willing to fully support their own "open standard". Bottom line: the files out of cr2hdr are not CinemaDNGs (an extension to the DNG standard) and Premiere only opens specific "flavors" of CinemaDNGs, basically only cDNG files that come from specific cameras (or cDNG files that are very similar to ones by specific cameras).

Many of the MLV/RAW converters output cDNGs that are compatible with Premiere and others, but cr2hdr does not.

AFAIK, MLVFS is the only converter that can output dual ISO converted cDNG files that will open with Premiere, and only the Mac/Linux versions have this capability (Windows version is far behind and unmaintained). So you can either use MLVFS on a Linux VM, or use something besides Premiere (like AfterEffects) to convert the DNGs to some video format that Premiere can read.

MLP for mac will repack the dual iso dng files so that they work in Premiere as well. (Thanks to cpc).
What is needed is this text file in the A_lut_hold folder.
MLV_RAW_dng_repack_16bit.txt

Check page 2 and page 10 in the user_guide to start with. I think the info there is enough.
I assume you have the MLV or RAW files still or did you obtain the dng files some other way?
Tell me if it worked or write a line in the MLP thread.

Don,t forget to add
MLV_RAW_dng_repack_16bit.txt

Inside the folder A_dan_log_3d_luts  you find the dcraw_FFmpeg_settings folder and inside of that folder you will find the file. Put that file in A_lut_hold folder and run MLP by right clicking a folder with MLV/RAW files.

Ok Danne im am a very newbie about computer staff so for me it is very hard since i dont know anything. I copied the only raw file a did to my mac where i installed all the MLP stuff correctly.
So my raw file in on my mac desktop but if it is necessary i can put it in a folder. Where do i find these Folders u r telling me? Than i have this MLV file on my mac desktop but when i right click on it on the menu there is no MLP as shown in the guide. In the guide it shows that MLP is under the "services" but when i right click i dont find it. It just suggests me to open it with miraViewer or i can choose other.

Ok, kind of hard to know what,s wrong here but let,s give it a try.
1 - Double click MLP to install. It should move to the library/services location.
2 - Put the RAW file in to an empty folder
3 - Right click the folder with the RAW file inside of it. Here MLP should pop up in the services menu?
4 - Select MLP and it will create the two additional folders inside the folder
5 - Go and get the MLV_RAW_dng_repack_16bit.txt file and add it to the A_lut_hold folder and run the MLP workflow once again by right clicking on the folder again.

If these steps doesn,t work could you redo all the steps from scratch and create a screen recording of what you are doing?

Ok Danne maybe im hard of hearing but i still dont get it.
I understood that if i would found the service tab and mlp it should make 2 more folders and one should be a lut hold....but where do i find MLV_RAW_dng_repack_16bit.txt ?????????

Than...i did all the steps u told me and i dont see the services tab. Could my Mac osx version be obsolete for this? Can i open the raw file opening first MLP automator and then dragging the file in?

Thank you

Everything is possible. If you added the MLV_RAW_dng_repack_16bit.txt file to the A_lut_hold folder it should work. What version of premiere are you running?
I also uploaded a new version of MLP in the MLP thread which fixed the problem before.

Could you test this image sequence in premiere pro and see how it reacts?

Strange. Only file in my A_lut_hold folder is the MLV_RAW_dng_repack_16bit.txt file.
Did you wait until the automator wheel dissappeared(up in the top of the window? It could happen you didn,t wait for the repack step to finish?
Also try downloading the latest version from the MLP thread now.
