version 8.5 first postReworked the speed_preview workflow.
http://www.magiclantern.fm/forum/index.php?topic=13512.msg147712#msg147712By right clicking on a raw/mlv/mov/MOV file you get one preview png frame from the chosen file/files works with following files.
- MLV/RAW regular files
- Dual iso movie files
- Higher fps, 48, 50, 60 fps (will autocorrect aspect ratio)
- HDR recordings -
You have to put in the word HDR in the file for the preview to recognize it as a HDR file! example M09-1234hdr.MLV- MOV, mov regular files (might be handy previewing 3d luts in general
Main usage is for a fast workflow with trying out 3d luts and checking CR2 white balance before taking of in the PRORES folder.
Simply add the chosen lut and/or the CR2 wb file next to the files and run the preview service.
Start up idea I had from dmilligan compression mlv tool which works with an automator service.
for f in "$@"
do
By adding above it works on selected files.
Then I added below for listing directory
cd "`dirname "$f"`"
Incorporated 3d lut, wb support, used mtime to only erase 30 sec old clips and used g3gg0, A1ex cool mlv_dump
-f frames
to extract only a few frames from the file. This and a lot of other stuff

All scripts are provided in the download package.
Added some more luts created in da vinci resolve. Will be automatically copied to folder when using the speed_preview on a file.
