MLV To Movie


- Native Mac OS X application written in Objective-C.
- Queue management to process as many files as you want.
- MLV files can be added to the queue from different directories.
- Movie files are build in the same directory as their original MLV files.
- DNG extraction with MLV_Dump.
- RGB conversion with DCRaw (parallelized for better performances).
- Movie conversion with FFmpeg.
- Dark, flat and flat dark calibration with automatic averaging of MLV files.
- Lossless export AVI (codec rawvideo; yuv420p) and MOV (codec h264; qp=1; yuv420p).
- Preview export AVI (codec mpeg4; qscale=1; yuv420p) and MOV (h264; qp=17; yuv420p).
- Sound export if available (PCM S16 LE for AVI file; AAC for MOV file).
- Prevent computer sleep when working.
NB: MOV quality is not perfectly lossless (qp parameter should be set to 0 and not 1) to be readable by Quicktime player.

Software requirements:
- Mac OS 10.9 or higher.
- 64 bit processor (Intel Core 2 Duo or higher).
