Fast Export: MLV to MP4
An idea to implement MLV to MP4 transform is quite natural. As soon as you have raw footage, you will finally need to do raw processing and save the result. This is quite complicated task, because it involves a dozen or more operations and it takes too much time. In the Fast CinemaDNG Processor software that task could be accomplished via external FFmpeg.
Fast CinemaDNG Processor software can do raw processing with super high performance on GPU, actually in realtime or even faster, and after that external FFmpeg can encode processed frames on CPU or on GPU. You just need to open your raw footage, define parameters for raw processing on GPU, and set path to external FFmpeg software to implement final encoding.
Full version of FFmpeg one can download from www.zeranoe.com. Then you need to install it to your PC and set path to ffmpeg.exe in Options dialog of Fast CinemaDNG Processor software.
To start encoding with external FFmpeg, you can utilize the following command line:
-c:v mpeg4 -q:v 2 -r 25 "$OUTPUT_PATH$/$OUTPUT_BASE_NAME$.MP4"
where "-r 25" stands for output frame rate 25 fps. If audio file reside in the current folder, FFmpeg will include it automatically.
One can utilize h264 encoding as well, but please bear in mind, that there are some limitations on output resolution, and you won't be able to do such encoding for arbitrary resolution of your footage.
