oh btw.. this i completely forgot.

when i import the audio clips from the cam into premiere those wavs are always way way way too long. like several minutes when a videoclip recorded is just like 30 seconds long. the wavs themselves seem to be ok'ish judging the content. after clip has ended there's only empty audio..

didn't the wav clip get ended until a new videoclip was started?! or something like that?

Easy: Don't use a 7d at all (port not stable yet). The T-Word might be tested more on 7d atm, but code-wise it's more experimental so your best bet is to support a stable 7d ML version with filing good bug reports and testing nightly.

as said i tried a ML nightly and it locked up my camera when doing some testshooting.

without all those bells and whistles (raw and such) i had hoped ML would be stable to offer basic recording stuff + focus peaking (if canon doesn't make it include this... *le sigh*

As i can't find the tragic lantern Thread for 7D anymore i post it here..

The last 2 weekends i've been shooting with tragic lantern (as magic lantern hung up on my cam three times at random actions and that i don't want to have in production..) with the cam set to ntsc and shooting at 30fps (which seems to be 29,97 infact..?!). audio was set to separate wav as i thought i would have any benefit from it.

recording with focus peaking to standard canon mpg went pretty flawless so far. i'll post the numerous crash logs when i get home. had to pull the battery a couple of times which was not really mounting faith in the current development.. :-/

with separate wavs i missed onscreen audio meters, so it was pretty much a guess-and-run filming stuff. luckily i have the audio from my rode videomic pro passed through a zoom h1 to the camera. i hope this saves me from unuseable audio if needed..

and i got me quite unawared that separate audio needs canon audio to be deactivated. i noticed that before shooting the actual clips luckily..

the worst problem sofar was the on some clips i have a severe drift between audio and video! an other clip from the later day without changed options (only battery because it died on me), the audio for the 30seconds we needed seems to be consistent.

the earlier day clips show a drift even after some 30 seconds. how the hell can that be?! i hope i can compensate with the H1.

editing is done via premiere with project and clips set to DSLR at 30fps.

so what build and options can be used for serious production shooting? no raw needed, just some stable and consistant working stuff...

but as said i switched ftp override to 30. but the recorded clips are 25fps. atleast vlc told me so?!

am i missing something?


about the sound - really bad. any way this could be changed anyhow?

ok, i can switch videomode to pal, so i managed to record 30p on my 7d. this should work on the m, too? or?

hello guys,

i'd dearly need my EOS M as B-Roll this weekend, but i'm having troubles with FPS Override and Sound in general. I'm not going to shoot raw, i just the cam to record standard movie but at 30FPS.

due to some reason the cam often (always?!) switches off sound recording in the canon menu. i do re-enable that ofcourse.

in FPS Override i active sound recording into a seperate WAV but i don't see any wav-File on the card after recording. no sound in the movie file, too.

does sound recording on EOS M work at all? until some minutes i always got "sound disabled" on the display when starting recording.
but atleast this doesn't seem to occur after i disabled loading raw modules at all.

the worst problem is that FPS doesn't seem to work at all. when i replay the clip with VLC on my laptop it always says 25FPS just as i set it up in the canon menu.

any help would be appreciated.. am i just overseeing something? or just too stoopid?!

h.264 can record 60fps but only at 720p

raw can do full HD in crop mode (x5 zoom)  But only TL have fps override.

mhh sad, i'll stick to 30fps then. worked last year that way, too.

maybe i'll shoot raw though. depends on if i find time to test it out this week.

just a quick question from work, as i don't have access to my 7d at home..

for a coming project i'd need to record stuff at 60fps (video playback will be direct from pc to beamer via h264 codec). most preferably non-raw but yet 1080p, shooting normal mpg will be sufficient.

is the current magic lantern (with FPS override i guess) working on 7d without problems in this mode/configuration?

Max is 91, mlv_rec will get better for sure, but we're missing ~10MB somewhere.

mlv rec only does 1728x694 and no more in y resolution? writing seems to be continous though.

Its plenty fast. Turn off GD and dialog timers in the debug menu and you should be able to record either the full 17XXx115X or the 17XXx1038. In zoom it does ~1038 at 30P or whatever you can make with 75-77MB with FPS override on. The benchmarks are almost never what it will record with the module, they only seem useful for me in play mode as it shows I have a 90MB/s card and I'm missing ~9 MB/s somewhere from the "wonderful" canon ui.

mhh.. me stupid? i don't see a resolution above 17XXx972 or such? did i oversee something? need to test zoom a little further though.

Press play.

ok, will try that. interestingly the cam/display stayed even on even when the cam was switched off - shutter went down, but the display was on.

Only way to break into the 80s is have no FPS override and record in that dead 10x mode.

so the card is fine? wish it was some megabytes faster to achieve some more resolution.. ^^ :-/

do you think we will be getting any closer to full hd resolution with the write speeds due to optimizations and such? i guess the write speed is already maxed out..?

i've been further testing the card and raw and it seems i can't get the card beyond around 73MB/s. is that ok or should the card deliver more throughput? with modes with a higher MB/s value the buffer fills up after some 1000 frames or so. as said the the value given in the resolution menu is quite correct - sadly sometimes..

10x zoom locked the cam. had to pull the batteries to reload the cam.

once had a lockup when entering the menu, changing the FPS and resultion and then starting recording. only happend in one out of 20 recordings.

tried different FPS and resolutions. could not reproduce the ERR message i got friday.

need to try raw + peaking again. but there's no peaking without global draw i guess?

i'm still struggeling with continuous raw recording. any experiences with raw + 64gb komputerbay cards with what options which resolutions should allow continuous recording? i'm still unsure if my cards doesn't deliver the promised speed or if i'm setting some options the wrong way... what are the best options for 7d at the moment?

i still find it hard to get a decent continous recording because i'm most of the time running into frameskipping due to full buffers.

to me it seems the card is slower than it should be..

@1%: do i have to re-update the .fir when the camera goes into sleep/standby?

strange. when i switch to 5x mode i can maximum record about 30-40 frames then recording stops because of skipped frames.

i'm having severe frame skipping issues now with the new card. can't get it to recording without skipping frames any more. at any FPS may it be 23,79, 24, 25 or 30. 5x or 1x. tried different resolutions. at 1920 i can't get beyond 10 frames or so.

pretty much out of ideas what could be wrong..

once the camera had locked up when switching to 5x mode and starting recording. couldn't reproduce it though..



did some more tests. seems like the infotext when switching resolutions is pretty correct. when it's green i can continuosly record. so where does this thing gets its information from? seems like my card doesn't make any more than around 70mb/s? or is my cam too slow?!

when switching to 5x mode i really have to lower resolution. not even close to beeing able to record in around 1920.

once even liveview froze.

also changing zoom seems to slow down recording even with global draw off. maybe that magic zoom does interfere here?

got my 64 gb komputerbay card yesterday. but yet i'm not sure if the card is fast enough, or if i missed an option that should be set?

any possibility to update the first post with the most important settings for optimum raw recording performance?
i guess it's not just me who sort of lost track on the stuff-to-do over all the pages in the different threads..

is there any common average what values such a card should produce in the benchmark?
mine was like 46MB/s write and 52MB/s read with the first 2048 chunk..

Got my Komputerbay 64GB card yesterday. What Read/Write speeds should a card like that show in the benchmark? I got like 46MB/s on a 2048 chunk.

Recording 1x1 on 1728 stopped with a Frameskip after some seconds. Second try didn't stop and went on fluently.

Before heading to bed i tried recording 1920 in 5x crop mode, but that stopped recording after the first frame.

Right now i remember the hint to set jpg quality to S. Does that improve recording? Global draw had been set to off.

FPS Override Firmware was loaded and FPS were set to 25.

Build was the latest test build from 12.09.2013

haven't tried the latest builds, but have the audio meters return also to the screen when NOT recording? i'd find this a major design flaw or bug to be honest.. but that's just my two cents.

Thanks to ML for making this .FIR available for 7D. Just installed, doing some tests and noticed:


1. ML doesnt work when cam is wakend after power save(sleep) mode. ML need to be reInstalled. No auto load.

2. Magic Zoom, does'nt work with f.ring (tested with tamron 18-270mm), only half shuter works.

3. NO audio meters in normal L.View, (while in REC is OK).

4. No audio control, too much bg noise.

5. Hope for HDR video soon..

i have asked about 3 and 4 already, but noone cared and i got no reply on that. no audio meters when not recording is not really helpful. afaik in alpha2 it was different..

Just like the 50d Thread this is not about a specific function and module, rather than to get an overview on what is still missing in the port, and what still needs fixing. as 7d development is spread like over 3 threads it gets a little complicated to stay on track with whats happening where.. ^^

7d - to my knowledge - has atleast two versions around:

- Release Alpha2 which does NOT autoload and may be rather outdated with features by now
- trunc/fork (?) of the current unified version, compiled for 7d and used for bootflagged cameras with autoload of magic lantern

the autoload version (in the dropbox from audionut) should be the most update version for 7d around including dualiso module, ettr and such. burst silent picture/video works for about seconds.

raw video is beeing worked on and not included in any build publically available?

what i got out of the forum stuff like fps override is missing and i haven't found it in the menu?

audio meters seem to be just displayed when recording a clip, not when camera is idle (in liveview).

any other stuff thats needs beeing worked on?

didn't fully check every option yesterday - have just been clicking around the menu and trying out options and stuff. i need to compare it to alpha2 for differences..

You could always clap loudly, it would register a sharp peak on the audio and you could sync that up with any cameras taking video...

Or use a flash and set it off, would easially show on all the video and you could sync the video to the white light and roll from there.

used to clap and such, but i thought that beep feature should/could be used for that. okay, cam is not that loud enough for distanct mikes, but may be useable for onboard/onrig stuff..?

Push record and you'll see em (make sure audios enabled in canon menu obviously). as far as the beep. still havent found it.

mhh, so the audio levels are only visible when actually recording, not all the time? would be easier to get the levels right before recording a clip..

..where have the audio-meters gone? can't find the option to switch them on in todays 7D build from audionut?

any chance to make the camera beep when recording starts? maybe be useful to sync others recorders/cams..

noone knows?!

i installed ML via the tutorial perfectly easy on my 7D. yay!

question now - what's in, what's not? as for photo as for video. can anybody make a list of what's still to fix maybe? like FPS override which seems to be missing. haven't got that much time yesterday for testing, but it seems like the option for audio meters is missing now, too?

i'm a windows programmer by work, so maybe i can be of a little help. just give me pinch what's still to be found and i'll see if i can find a little time for hunting..

awesome, thanks for explaining (again)!

just two questions left:

1.) isn't the firmware.fir always the same so you could put it somewhere to download? for us lazy bastards.. ;-)

2.) why updating via eosutility? can't this done via camera?

so the firmware upgrade just get's launched and sets the bootflag, but doesn't change anything to/in the camera? i'm just curious about this bootflag thing.
