Time for a little update of 7D raw recording capabilities:
ONLY TESTED raw_rec module:
Lexar 1000X with todays built from 1% https://bitbucket.org/OtherOnePercent/tragic-lantern-6d/commits
Did not use fir update since FPS override now works without it!

2048x1152 at 30 fps - Up to 79.7 MB/sec 205 frames (6.8 seconds)

Cropped video mode (5X-but at 10X frozen zoom) at 30 fps
1728x972 at 30 fps - Up to 81.6 MB/s 3000 frames (100 seconds)

I like 1728x1152 or 56... wish there was a moire detector tho.

How i record in 10x crop mode with 24/09/2013 britom's build?liveview freeze when i try to go in 10x

Actually the recording is really 5X, but I am going to 10x so LV freezes and allows for faster recording at 5X

[ted ramasola]

In current build does 10x also freeze the image via HDMI out ?

[JCBEos]

Sticky something is on? Maybe some ML assert is tripped? I compiled last night and get no blinking.

Ok now it's gone... I maybee need to stop playin with menus... or stop drinking. Or both

Time for a little update of 7D raw recording capabilities:

Thanks Renato for posting your benchmarks! I recently purchased a KomputerBay 32gb x1000 and I was only getting between 48-60 MB/s so I returned it and bought a Lexar 32gb x1000. I became a little disappointed when I maxed out at ~80 MB/s. I was under the impression everyone was getting in the 100 MB/s range.

Is there a newer MLV_REC or did you have to compile something?

[RenatoPhoto]

100 MB/s only possible on 5D3

Is there a newer MLV_REC or did you have to compile something?

I compiled myself but only tested raw_rec module..  mlv_rec should be similar

Can you post the bundle please? :3

I was a little upset about  the vertical lines in RAW, its obvious pattern apparently indicated that those vertical lines were read related noise. But how come that the original CR2 doesn't have those vertical lines?

When reading raw.c and raw.h, some questions popped up into my mind. One of the biggest one of them is  like that, why the ev values are in float? Aren't EV values are in unsigned int instead? But I was not familiar with coding, image capturing and 7D project, so there was no immediate answer that I could find as the knowledge in these fields has failed me. Please forgive my ignorance.

[1%]

Someone said the correction for 5DIII stripes had some effect. Other than that I only see noise in high ISO/darkness

[mucher]

My bad, EV value is float. But there must be some formula to change EV value to bit grades.

[RenatoPhoto]

Can you post the bundle please? :3

Tried but dont have enough bandwidth.  sorry.

[mucher]

Second thought (actually third ), the DIGICs are already doing the best they can, so...forget about it. Sorry for the bothering.

new build: http://www.magiclantern.fm/forum/index.php?topic=7987

h264 is still broken but 1% will fix it soon

[arrinkiiii]

Alright  Thanks britom and one percent 

[Fringuello]

ML_britom_1%_24_Sep_2013_
Why do I activate the magic zoom in raw video recording will not function?

[1%]

Hit start again, it should turn off the MZ and start recording.

[Fringuello]

ok grazie

[danistuta]

Sorry...what is h264 video function?

[arrinkiiii]

...normal video mode by canon ??

Would you reccomend this card, and if so where do you buy it?
If its as good as the Komputerbay one's I would Buy 2 in stead of one Komputerbay.

[mityazabuben]

I cant say for sure how it will behave on 7D, bcs I didnt make any tests yet for compare them (will try to make in a 2 day). But, if we abstracting from 7D, I think its better and cheaper. Find it on alibaba, you can send an email to sales8@wellcore-tech.com for purchase order.

Made some test:
1728x972 (1156) at 24 fps - Continuous Recording
1728x972 at 30 fps - 80.6 MB/s up to 2352 frames (first time was slower, when shooting further its starting to work > 80 MB/s)

Cropped video mode (5X) at 30 fps
1728x972 at 30 fps - Up to 80.3 MB/s 2169 frames

Cropped video mode (5X-but at 10X frozen zoom) at 30 fps
1728x972 at 30 fps - Up to 82.2 MB/s 4300 frames

Cropped video mode (5X-but at 10X frozen zoom) at 24 fps
FullHD at 24 fps - Up to 81.7 MB/s 3000+ frames
In a ML format - 3700+ frames. Actually, on a Komputerbay I can rec ~6800 frames in this mode...

Just a question for any of you Resolve 9 users out there. I used MLV2dng to convert my video. When I brought the dng file into Resolve it was all purple and really distorted not readable at all. What's with that ?
