Heh, the regs are the same but trying it I just get shutter locked at 1/30. It does follow FPS tho... 28fps produces 1/28, etc.

//~ [REG] ADTG:[0x105f00cf]
//~ [REG] ADTG:[0x106100cf]



Maybe this part is wrong?

#define FRAME_SHUTTER_BLANKING_READ   (lv_dispsize > 1 ? FRAME_SHUTTER_BLANKING_NOZOOM : FRAME_SHUTTER_BLANKING_ZOOM) /* when reading, use the other mode, as it contains the original value (not overriden) */
#define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)

Log while changing shutter speed.

Without trying to set registers, shorter.

Hello All,

First off thanks for the hard work/community of this forum, really amazing. 

So just got a nice low shutter 50D and loaded up the June 28th build and it's working but a bit strange.  I can only shoot about 400mb of footage before it stops recording. Could this be buffer issues that I could tweak? In addition I just can't seem to be able to change the resolution size beyond the raw default. I have tried but my gray menu says "N/A" and even when I hit function I can't seem to trigger anything new.

I'm sure within the 84 pages of posts the answers are there (and I have looked) but any simple newbie advice would be great.

One thing to know:I picked up the Komputer Bay UDMA7 card that is 128G.  Could this be the problem? Maybe the it should be 64 or maybe UDMA6?



Thanks again in advance

J

Try this.  Getting up to 81.8mb/s on a 32GB Komputerbay 1000x now

Instead of Dialog Timers, find 'Small Hacks' in the RAW Video section and turn on.  This is the new that.
Also, in the most recent build, there is a 'Warm up Card' function, which preforms the first write on boot.

Thanks Guys for responding so quickly!!!

So i ordered the 32gig 1000X card today so I hope that takes care of my problems.

So DSmanning just to be clear what is the build you were referring to that I should use? So once I find this build its really as simple as keeping the old 2.3 fir replacing the autoEX file and add the "modules" folder to the existing ML folder, then it's off to the races? I think.

Will keep you posted when the 32gig arrives,

Thanks again,

J

The shutter blanking is used to compute the sensor duty cycle. Of course, if nothing changes there, it will consider duty cycle constant and will multiply it by 1/FPS (so it will follow the FPS).

Normal values (after NRZI decode) should be between 0 and FPS timer B - 1 (roughly).

You have checked shutter speed with expo override, right?

The register seems to be changing correctly in the logs though.

First log adtg.txt has the hack on, second one is no hack. Expo override was on to have movie mode shutters and no iso shifting.

It looks more like frame shutter timer than timer b I think.

What are the register values at 1/fps and 1/8000? (or 1/4000, whatever you can get)

I would like to do some more card speed tests on the 50D, but i can't figure out how to run the benchmark or where to run it. Is it a module which should be added manually to ML or a custom build?

nrzi_decode(0x7F1) = 1374, FPS timer B is 1380 by default, so the values look alright. Also, if ML displays 1/30, 1/60 and 1/7800, it shows the right thing.

So... where's the problem?

These are with just shutter timer. When I enable ADTG I can't change the shutter, its stuck at 1/fps.

once you load the custom FW and then load the module there should be a 'benchmark' submenu under one of the main menu items. I can't remember which however.
PS if you have a question about something you might need to ask it multiple times before getting an answer.  Almost all my tech support questions have gone unanswered on here, and the 'guide' thread does not help much either

Any idea why this is happening? Long spanned clip, not on the latest build. Processed through RAWmagic.

"Not on the latest build" - have you tried the latest build?

It's probably a footer issue. I've seen lot of posts with this kind of problem. Search for 'spanning raw files'.

There is no 'tech support' here beyond users and devs helping each other out. A lot of user questions have already been answered multiple times (though maybe not your questions specifically) and some users don't seem to know how to use the search function.

@guruaner - re: Benchmarks. You can find the tests in the 'Debug' tab under the cryptically titled 'Benchmarks' menu  ;) If you can't see it you must be using a build with debug disabled (though I don't know what build that would be TBH?).

I´m thinking about the 3x zoom mode.
Maybe it´s possible to use a B4 lens on the 50D with 3x zoom mode.
This is the theory

Great video.. I can almost spot the 50D footage just cause of it's organic nature.  Which shots exactly were the 50D's?

Thanks!

1st, 2nd, and 4th shots are all 50D. Much more but those should Give a basis to whats what.

The error I reported earlier with the corrupted CDNG. It seems to be only on an occasional basis. Any explanation? Also, in terms of frame rate, is everyone out there fiddling with shutter timers to get 23.976?

You mean 23fps with more shutter range? I can get 23.98x with all shutters.

@1% - I suppose I mean when you turn FPS override on, I don't get 23.976 straight off the bat. I have to tinker under advanced with the timers to get it, which I think might lead to some of my issues in post.

Probably not the best grading or best workflow but here is some footage shot with the 50D raw hack.

Another test with the 50D. Still learning how to handle the exposure, some shots overexposed, maybe i'm still shooting as if it was h.264 ;D

There are some shots where one can see the exposure changes produced by ACR.
