To windows users:
I ran into a problem with very high resolution footage using card spanning, with frames being corrupted.
It seems to be solved by updating to dokan v


"upgrading to the last 1.x version of dokan seems to have solved the issue... v"

what is this dokan for?


windows doesn't have fuse.  dokan is the alternative.  look at the first post on this thread for details.

the dokan link provided there is from 2014 and is a much older version.


Beginner here who's been using MLVFS recently for editing mlv files from my eos-m in Resolve and it is working just as I hoped. Except for focus pixels / pink dots in the video.
I tried to search the forum for solution, but could not easily find it (forgive me if I missed it). Only simple instructions I found were this:

Realized that there are several newcomers trying to figure out how to use the focus pixel map files so here's a quick tutorial:

The easiest way to get the map files is to download the whole repository from the downloads page:

Take all of the .fmp files in the focus_pixel_map_files directory and place them next to the MLVFS binary. I'm on a Mac so it is located in my home directory > Library > Services > MLVFS > Contents (doing Control click on the MLVFS in order to get into the package contents). Never used MLVFS on Windows or Linux so I'm not sure how that works.

Same thing with MLV App, put the .fpm files next to the binary. MLV App is currently the best way to work with 5K Anamorphic files and yes, it is possible to export cdng using that application with fixed focus pixels and adjusted aspect ratio.

Either MLVFS or MLV App is a great way to get your raw footage into editing systems that can handle cdng files like DaVinci Resolve or After Effects. However -- only editing apps that use Adobe Camera Raw (like After Effects) seem to respect the resize and aspect ratio metadata in the cdng files so you'll have to adjust the image size if you want to use these dng files directly in Premiere or Resolve. You can also export to Prores or other several other file formats from MLV App and not worry about the resize/aspect ratio issues.

But the link is not working.
How do I remove these Focus Pixels in MLVFS now?

I have bash integration with Mlvfs through menu navigation in this app/workflow:

select "ml" from the root menu. Fuse from here:
Install apple silicon or intel dependeing on what machine you are running.

Thanks Danne for pointing to Switch, it's working very good. At least for non-dualiso files.
Perhaps I'm doing something wrong, but when I choose option (10) to render Dual ISO and than A to activate MLVFS, I get following message :
QuotePlease enter your selection number below:
ls: /tmp/no_files: No such file or directory
ls: /tmp/SCALETAG: No such file or directory
ls: /tmp/DUALISO/crop_rec: No such file or directory
fuse: unknown option `-n'

and the Finder seems to freeze, I need to restart.
Do you know why this happens ?


Dualiso is not very nice in mlvfs.
Rendering to prores is quite nice.


MLVFS for Dokany 2.1

- Install Dokany v2.1.0.1000

- Edit mlvfs.bat by changing the path to you MLV files (or just the letter of your SD card) in the argument --mlv-dir=E:\DCIM\100CANON\ or use it directly in a command prompt

Nvm, it produces white dots on the dark parts of the picture.

If someone need a workflow that works with the free Resolve version, I shared my files there:
