If the developers can find a way to encode the metadata the right way, Resolve should be able to recognize it right off the bat.  Unfortunately, when I open my clips they don't seem to have any of the metadata stored...  I'm processing through mlv.dump.osx for 10.7...

Has anyone tested a long clip of a more thane a couple minutes? I have only tried short clips so far and they seem in sync. Are longer clips still in sync?

-m question...

What file extension should we be outputting the metadata to?  What can read this metadata?  Is the audio track information being encoded on the metadata track?  Is this information used when processing to .dng, or does additional software need to be written to re-encorporate it?

Thanks!

Excellent work! I just started testing the new mlv-sound.mo  and the MLV viewer.

So far the MLVBrowser exports (wav + dng) the dng and the wav.  The sound seem good but the dng have green cast.

If I export to RAW + wav and then use raw2dng then the dngs are OK!

Finally my movies will not be muted.  Thank you very much.

I will be testing this further as I have time....

Merry Chiristmas and thank you again.

g3gg0, is there any possibility to implement 44,1 to 48khz conversion in MLV browser?
Resolve 10 dont accept 44,1, sure we can do this one by one by hand but the workflow would be much faster with ready 48khz wav out of mlv_dump. What do you think?
Cheers

Hi, i still have problems with "lowered" and "slowed down" sound in my wav files (5d3). If you have everything synced all the time could you please tell me your settings in mlv tab? Thanks

Got it. If you just click on wav and open it in say windows media player - does it play normal ?  Could you please check one of my previous post in this thread with dropbox links and see those two short clips  and the diffetence between them? Thanks

Sampling rate selection will be added soon.
dont know if it is possible to select 48khz in camera.

Thats great, i tested many times, also with yesterday nightly build and of course newest mlv rec pre built. Still having the same problem. Converting playback rate (not just resampling) from 44,1 to 48khz in goldwave makes wav sounds correct (it shortens it a little bit). Strange thing is that nobody else is having such a problem...

48K will be great if it's possible. I am impressed with the audio recording now. It now makes 'run and gun' type filming a much more realistic possibility. The audio thing is a game changer. Again. Thanks for all the work. It's much appreciated. :)

Can we have 24-bit too? (only joking! ;) :D)

Did you try setting still image quality to a low jpg setting and rawphoto off? WIth this I get continuous 25fps 1920x1080 with audio.

Here's a quick bash script for anyone wishing to run the OS X edition... move MLV_DUMP.OSX to /usr/bin and rename to MLV_DUMP then run CHMOD +X /usr/bin/MLV_DUMP

Save the script as dumper.sh in the same folder as the MLV files ... I usually copy everything to my desktop.  Usage of the script: ./dumper.sh <input.mlv> <folder name>

mkdir $2
mv $1 ./$2
cd ./$2
/usr/bin/mlv_dump -o $1 --dng $1

update:
- mlv_snd now allows to select desired sampling rate (48000, 44100, 22050, 11025, 8000)

not quite correct.

this:

thanks dude, forgot the /.  i'm trying to figure out how to list all .mlv files to a text file then load each line, call the file the original file name, and export to a directory with the file name before ".MLV"

will report back.
