Title: Black screen when recording 10bit/12bit raw on 600d
Post by: awa101 on August 23, 2017, 11:31:58 AM
Hi guys,  I can record 14bit raw with no issues but when I record at 10 or 12bit the footage appears to record with no problems however upon playback the mlv Is just black footage. I'm using the 10/12bit experimental build. Thanks

Format your card n try reinstalling ML. Mine worked that way.

It works for me too. The thumbnail on windows explorer will be black, but when you open on a raw processor it just works.
Try reinstalling, if even after that you cannot record, put here your configuration files, you may have some bad config...

I have the same problem with a 700d, how did you fix it?

@Bassbeats
Do you mean playing the 10/12bit uncompressed MLV in the camera using mlv_play?

You should enable raw_twk.mo to get normal preview --> but raw_twk.mo is not good 100% it have some problems and it will affect or damage raw footage in some cases.

Why you didn't use a build from crop_rec_4k branch (https://builds.magiclantern.fm/experiments.html) and try to record 14-bit lossless instead?

If the problem when viewing it in PC --> Try MLV App (https://www.magiclantern.fm/forum/index.php?topic=20025.0)

That did the job! I enabled raw_twk
Thanks a lot mate, thanks :)
