Hey guys,

Thanks for your great work on magic lantern! I've used it on multiple cameras for a while and it's been really helpful.

Today I installed the latest build (magiclantern-Nightly.2015Jun23.7D203.zip) on my 7D. When auto-restart is on, it restarts the camera even when I stop recording by pressing the button myself (rather than only restarting when the camera stops recording on its own). Is that a known bug?

Hi all,
Issue: Corrupted 7D CROP RAW video

Background:
Canon 7D 203 firmware with ML nightly.2015Jul02.7D203
CF card: Komputerbay Professional 64GB 1066x
Did not use any other modules than raw_rec with RAW video on.

When recording normal raw video everything is ok.
But when recording with raw video in CROP mode, then the video will be corrupted (can already be seen during recording in live view - there is all kind of textured areas jumping around in the view...)

I did try an earlier nightly build with the same problem, so I'm sort of irresolute on what to do next.
Please advice!

Thanks,
Jan

Could you try with mlv_rec as raw_rec is somewhat deprecated and tell us ?

I did try with mlv_rec also earlier, which caused the camera to crash during recording ONLY in raw CROP mode (this was with an earlier nightly version)
Now I tried again with the latest nightly in mlv_rec mode, and again it crashed only in raw crop mode (normal size raw worked just fine).

Here are the log files I found on the card:
CRASH00.LOG:
ASSERT: !IS_ERROR( TryPostEvent( this->hTaskClass, this, EV_VD_INTR_LV, NULL, 0 ) )
at LVState.c:485, task ?
lv:1 mode:3

So the problem is associated with only CROP mode in both raw_rec and mlv_rec

I did new tests with less video resolution on the crop raw video, but the problem did remain.
All my raw crop video tests up to now were made using the ML view on the live view.

BUT!!, when I changed to one of Canon's views in live view (by toggling the INFO button), then I were able to get raw crop video without failure both in raw_rec and mlv_rec mode!
So I can circumvent the problem this way, but I loose a live view with correct display of what area I'm filming.
I think I have a sort of halfway solution to my problem...

Did you have Global Draw turned on? Turn it off.

Yes Walter, I did have Global draw on, but when I tested in off position I were able to capture raw crop video. So it seems that this issue has to do with all tree ML live views in raw crop video mode.

Is it just me or does 7D ML seems very unstable lately? lots of ERR70

anyway, crash log:
Code: [Select]

Sorry Walter, By "all tree" I mean the "LiveView", the "QuickReview" and the "ON, all modes" in Global Draw.

Another issue, I have experiensed it twice now, that the 7D battery was flat after having my ML CF card in the camera over night, even though the cameras power button was in OFF position? I'm I dreaming or what?

Zip contents of ML\Settings, upload it somewhere and link it here. Will try to reproduce.
I'm used to remove and reinsert battery. Power off setting isn't breaking power line but just telling the cam to shutdown.

Hi Walter
Hope these settings was the one you requested.

ML nightly June 9,2015.  In MLV record in regular mode the movie menu, raw video(mlv) shows the resolution and below it show write speed needed at 23.976fps.  Which is the fps I want to shoot in.  But when I move into crop mode it shows additional resolution setting but only at 29.951fps.  Does that mean in crop mode you can only shoot at 29.951 fps?  I'm sure this is covered elsewhere but couldn't find.  Thanks.

You have to tweak fps settings.

OK.  I've done that before but you loose sound.  I was hoping to have both.  It's essential that you import video into editor (I use Sony Vegas) at the exact fps setting you choose to override to keep audio and video synced. I learned that the hard way.  :)  Thanks Walter.

So, quick backstory, i recently bought a Komputerbay 1066x 64GB

testing on MAC i got 149mbs read max, and 122mbs write max
Blackmagic on MAC 133 read max, and 121mbs write max
Testing today from a Windows Surface 3 CrystalDisk -- 149mbs read, 129mbs write

i was thinking of returning this card as it is still not quite 155 / 160 or consistently 140 write and my Magic Lantern benchmarks were poor

:64.8mb/s in movie mode, 54mbs read
74mb/s in photo and playback write
best results 86


today i installed the new july build and did a few restarts and in playback i got a massive result across the board:


But movie mode was still lacking...


I understand the limitations of the Canon 7D but want to maximise my speeds and have seen results nearing the 90mbs write
currently i am hitting around 78/79 maybe 81mb/s but it skips a frame and freezes up trying to write the data, sometimes its able to stop after a skipped frame write the 5/10 seconds and move on but others it will freeze the entire system.

So
1. should i return the card - the chipset is the old AB so could get an AC and i am still only getting 120mb/s write?
2. is this freezing normal what can i do to prevent it?

Thanks everyone great work so far very impressed.

IMO: Card absolutely ok and within expected performance range. 
Freezing needs to be explored, though.

Sounds great if the latest version works in crop mode and 24 fps/s.

Two questions here...

1) If I haven't upgraded in several months, but last time I shot it was great- should I wipe it clean and re-install before my shoot tomorrow, or just use the older version since it worked fine?

2) if I don't touch any fps override, then it's 23.976 fps right (assuming 24fps is selected in canon menu)? Should I rather use fps override and set it to 24?

I've tested recent relise, and it is fine. Haven't had a power down / cf eject / freeze in couple recent releases, tough I never could really pinpoint he cause, previously it froze up if I ejected card on switched off camera and putt an other one, had to eject battery as well. not always, could not understand why, but it happened once in a while. for last 2-3 releases, have never had this bug.

but yes, I've tested it, seams stable.

if you select the 24 in canon menu, then it is indeed 23.976, if you have no particular reason you should not touch the fps override.
