Trying to use your script.
I think this could be exactly what I look for when creating proxies if I got it to work.
The very first time I used it, I got it to make a composition and render one dng sequence to a h264 file. But now it only imports the sequences and thats it.
Now there´s a feature to create comps and output modules from already imported material, i.e. if the script failed to generate it automatically you can do it manually now.
How ? you mean manually make a composition for every imported dng sequence in after effects and add it to render queue? I guess you don't mean this, cause that ain't nothing new

Other than that, I found out that if I had played the DNG sequence in MLrawviewer, the script will state that there is a missing file. But this is because MLrawviever makes a .mrx file which the script somehow interprets as a missing frame or obstructing its count of frames.
.idx files created by mlrawviever and in camera mlv_play will interfer with the script aswell and make it not import.
So best thing is to have a folder with DNG folders that contain nothing else but DNG's and WAV files, then the import works.
Please let me know how to make compositions and render from already imported sequences.
Thank you.
EDIT: like seriously, 10 seconds after I posted this and looked at the "Selected material" I found out how to use it.. I thought it wasn't working before as I was trying to specify the location of source files of the already imported sequences.
So yeah, just selecting the material in project manager and clicking Run under "Selected Material" worked.
Awesome script! Thank you so much! even though it doens't work on first import, its still so fast to import then select the material in project manager and make the proxies! Exactly what i was looking for!
