can you check if you had a lot of .idx files on your card that wasn't able to play back?

No I had only idx related to the footage. Also I deleted all IDX and try to replay again - nothing.

header start looks a bit uncommon.
Code: [Select]
[MLVI]
[RAWI][INFO][RTCI][EXPO][LENS][IDNT][WBAL][STYL][VERS]+++++[EXPO][LENS][RTCI][EXPO][LENS][WBAL]
[VIDF][NULL]
[VIDF][NULL]
[VIDF]...

is this recorded with mlv_rec instead of mlv_lite?
Yes

hey alex i will say that i used the exact settings on both versions and even made sure to  only activate  the raw record/play/sound module. installed the different versions both twice just to  make sure that the install didnt mess up the first time. but i will provide screen shots. what is it again that you want me to screen shot? the raw video settings and for the speedtest do you want me to use the card speed test in debugging mode? thanks

The writing speed indicator from the MLV recording module (either during recording, or afterwards) should be fine.

I don't have a 700D to test, but I can try to reproduce on 5D3.

i just test the 10bit expirimental build on 2 july 17 for 70D. just after  started recording the camera hangs. stop buttons or any other buttons wouldn't work so i have to pull out the battery. i can share a video very soon if needed to see what i mean


edit: while the camera is recordng if i press any buttons like stop button, my camera hangs so i have to pull out the battery. however the file is save in the memory card. i can't preview in  the camera but i can preview in my laptop with mlrarviewer

That's unlikely to help. A lot more helpful would be a detailed (!) list of what works and what not.

If raw video is not working at all, it could be worth trying other ways of capturing raw frames from LiveView (silent pictures, raw_diag) or other builds (e.g. lua_fix).

oh hey alex sorry for the long response time but i went to go download the june version again to show you but it was already replaced by the july version sorry.
good thing is the july version doesnt seem to have the problem the june version had and compared to the may version seems to be even better! for instance the write speed seems to be more consistent. resolutions i use to use that technically did shoot continous (even though magic lantern had a yellow camera icon by it) now are recognized by magic lantern as a continous shoot.  so that feels good as far as usability goes.
one thing did happen when i tryed to play back the file though. it started gathering all the frames and then it slowly wrote this into existence (see images) and then it was just plastering onto my camera screen and the only way to get it off it seems was to turn off the camera(i could till see through it and it wasnt frozen)








btw i mean play back of 10bit raw recordings

With care or not at all.
Depends on the cam you have. Top of page -> Downloads -> Downloads (drop-down menu) -> Experiments.

@Admins: Please edit first post of this thread and add some links/text/instructions according to other threads.

I see that 4k crop build has the fix of the black frame issue at the mlv_play module...Could anybody add this fix to 10_12 bit build?

I see a problem with ghost images in this build. It shows the overlay, but immediately prints error log.
Looks like it was resolved in Unified. https://bitbucket.org/hudson/magic-lantern/commits/e0c1b48a2558975e23545eaeea9eced6de72ab97
