@Levas

Thank you very much for the new crop and the SD UHS. I will test the new crop and report back. I use Sandisk extreme pro and it benefits from the regular sd_uhs a lot, so this new version should speed up things..

Thank you once again, you are a legend.

@marcelolippi Make sure you have no clipped highlights. Picture should be a bit underexposed to get the best result, especially if you have large bright/white objects in the frame. GD causes pink frames in crop mode, so unless you don't mind them, use Kill GD, of course then you won't have LV and no framing, if you need framing, afaik your only option without pink frames is MCM rewired preset. I also reduce audio sampling to 11KHz, this helps to give more room for video. Tonight I was able to film two clips (~12min each) clips of band performance with 1120x1890 14bit anamorphic (used 4K preset). It was dark, in daylight it won't give me continuous.

Gentlemen, please read this thread starting with page 71 post 1765 to familiarize yourself with the limitations/quirks/oddities of ML implementation on the EOS M. Answers to most of your questions contain there. I'm doing exactly that the 2nd time now to fill in the gaps I missed the 1st time

I've decided that my previous test might have been flawed because I compared two 16:9 frames and for proper positioning you need to see where the crop positioned relative to the full sensor picture. I redid the test. Here you can see a full frame picture 1824x1216 res and on top of it in orange is a 1120x1890 frame form 1:3 anamorphic preset stretched to 3360x1890 and then on top of that there is 2304x1296 frame from x5 zoom preset for reference.

Sorry the picture is out of focus, I forgot to focus properly

@Levas

Tested presets - all work well, continuous in both as long you don't get overexposed large white objects in the frame.

Re centering, not so rosy. Here's where the current 1120 x 1890 crop positioned on top of FF frame.



Need to be moved up and left. Are there any regs I can try to move the frame?

Ideally we would have a setting with vertical resolution adjustable, maybe withing a short range, like 1880 - 2144.

Thank you!

Thank you Levas!

Will test it and report back.

Yeah, I realized that your original 1824x1842 1:3 preset (in 16:9 1088x1842) was close to the maximum resolution continuous recording we can get on these cameras. A slight bump in resolution like this is probably all we can have.

I did some more testing to try to establish some pattern in pink frames.

Used your latest preset 4k Anamorphic rewired @14bit, 16:9, 1120x1890 res.

1 In LV with GD on I got this
clip 1 1m30s - 10 pink frames
clip 2 1m12s - 13 pink frames
clip 3 1m7s - 10 pink frames
clip 4 23s - 4 pink frames

2 In LV with Kill GD on I got
clip 1 1m30s - 0 pink frames
clip 2 54s - 0 pink frames
clip 3 50s - 0 pink frames
clip 4 50s - 0 pink frames

I also ran tests with your 5k anamorphic preset. With Kill GD enabled, out of 10 clips I only got 3 pink frames in the first one (maybe some settings didn't update correctly?), all other were pink frame free.

Not sure if this info is of any value, but could it be that GD somehow contributes to PF effect?

Another thing I noticed is that in 5K preset video 'jerks' often. After watching clips for a while I started noticing that it happens when the camera changed direction of movement. I think it might be related to IS not working properly in this preset? In 4k preset I didn't notice any jerkiness. Sorry if this is known or has already been discussed.

Ok, I will try these.

So, the 6D and EOS M have different values in these regs? Can't take them from one put in the other?

If it's of any help.. I don't think I ever got any corrupted frames on my 6D. I get 2nd and 3rd frames corrupted all the time, they are practically never good, but apart from that, I can't remember ever getting a pink or mangled frame.

Ok, Thank you, found it, will test tomorrow.

I've noticed that your build is so smooth and responsive, feels great comparing to my 6D, which feels a little sluggish. Also things don't seem to break, at least I haven't been able to break anything so far, which would require a reboot.. So, congrats, feels very polished.

About pink frames.. I though they were caused by corruption that occurs when a camera runs out of processing power and can't keep up with the data flow or recording it onto a card.. But my observations with today's footage don't seem to support this.. I observed pink frames in places in my footage where I would expect them the least if my theory was correct, like I pan the camera from a brighter spot to a darker spot and a pink frames occurs in the dark spot, where, according to what I've read, the data flow should be smaller.. Strange 

I see, I'm a 16:9 guy, so this script won't work for me..
Where is this Kill global draw setting?

Danne

I tested your last build today. Very nice!
Still get some occasional pink frames. Can't narrow down what's causing them.
The statistics from today is:
5K anamorphic
1136 x 1918 - out of 5 clips 2 had pink frames - 1 and 2 in each
1184 x 1998 - out of 5 clips 1 had 1 pink frame
new 4k anamorphic rewired
1136 x 1900 - out of 3 clips no pink frames

BTW, what's the difference between these two presets?

Will do more tests tomorrow. I film some clips in LV and others in LV with GD off and yet others on non LV mode, maybe this has influence.

Thank you!

Oh God, sometimes testing can be so time consuming, difficult and inconclusive.

Spent 3 hours today testing presets for the 6D an EOS M. In some cases I would get one result for a preset just to come back to it some time later to get somewhat different result. All together I ran about 60 tests.

From the two 1:3 presets I only managed to test the 1640 x 2025 25fps one before I started loosing light.

All tests are done with 14bit recording.

# In LV with GD enabled and everything else disabled (histogram ets..) I was able to get more or less stable continuous with 976 x 1952 at 25fps (by more or less I mean if I direct the camera at a large white object like a wall or a roof taking at least 1/3 of the view, I get first red indicator and then stop)
# If I disable GD, I can film continuous with 1040 x 2052 at 25fps with similar remark.

at 24 fps we would be able to go a bit higher of course.

Do you want me to test the 24fps preset too or can you calculate from these results?

I think the current 1:3 presets should be left in the crop_rec for short clips and maybe new ones added for those who want continuous.

centering the view needs a bit of testing but should be doable I guess

Since I'm too dumb to code, if I can help with any testing, I'm listening.

Maybe you can find out what resolution is continuous by lowering the horizontal resolution of the current build, that way we can calculate at how many megapixel frame size it is continuous, and use that to calculate the needed vertical resolution for continuous.

I hear you. I'll do this tomorrow, It's 1am here now

[24fps]

Seems you are able to compile

Sorry, this is way above my head 

By reducing you will increase fps. GOing to 25 should be safe

I probably didn't explain myself clear.
The fps are fine, no need to change them.
If possible, would be good to be able to change vertical resolution in 1:3 presets. If this is impossible, then making another preset 1632x2052 24fps should allow continuous recording.

Did some more testing today of the latest 1:3 presets to see if I would be able to record continuously with them. Basically confirmed what I said before - they are good for short clips. In bright day light I couldn't achieve continuous recording no matter what I did (lowering exposure so there are no overexposed parts, disabling LV). When the sun went behind a big cloud and it became overcast I was able to record continuous with LV disabled in non-LV view (not sure how to call it). Of course the view was scrambled. I can work with this because I mostly film static scenes, but for many people it would be problematic.

Since we can't reduce vertical resolution in these presets, I tried to minimize the bitrate by going to the 25fps preset and setting 24fps in fps override. It didn't work, I got scrambled footage.

Would it be possible to make vertical resolution adjustable? If not, making another preset with the 25fps preset resolution at 24fps might make it continuous.

It would also be very good if we could move the crop from the bottom up and center it in the frame. Is it possible at all? The way it is now it's capturing the edge of the frame, which is not the best part of it, especially with wide angle lenses, where it get's very distorted.

Finally I get to upgrade my 60D to a 6D (used, sold by my friend)

Welcome to the FF world! I used to be a Sony only guy and was convinced that Canon sensors are crap (well, I still know they are.. not the best). But then I needed a backup/second camera to complement my A7R2 (which has the best sensor on the market in terms of noise/signal ratio). Since I have a lot of Canon glass, I thought maybe some Canon would work for me. After researching I discovered that the sensor Canon put inside this body (that was specifically developed for it and which even outperforms the sensor inside 5Dm3) is about the best sensor they ever produced in terms of low noise/high iso performance, only beaten recently by Canon 5Dm4. I shoot/film a lot in low light and this was a deciding factor for me. So, I ended up getting a s/h 6D.
Here's a nice comparison of the 6D sensor with other relevant cameras. 700D, I believe has a very similar sensor to 60D you had, so you can see how much of improvement you are getting.

was just high iso test of how much i could smooth out noise, is it better to shoot 1600 and brighten up or shoot 64000 and darken shadows.

I recently tried editing in DaVinci Resolve. One thing that impressed the heck out of me is very powerful noise reduction. It has this tool.. not sure what it does, frame blending or something, but i was able to reduce noise in some quite noisy footage (iso 3200 if remember correctly) to almost nothing without destroying details. It was like magic to me.. used Adobe stuff for years and have never seen anything like this! BTW, there's a free version of it.

There's definitely difference, but nothing a quick post processing won't fix. Here's you green frame quickly adjusted to look more or less like the cyan one:




I've been doing digital color correction for 15 years (photos and printers) and pretty much the only thing I care about is details. They can't be brought back if lost. Color can be made almost anything you want nowadays, especially with the power raw presents us.

These latest 1x3 presets you are using are made for 5 x zoom mode, which in this case means that shutter-time is correct in 5 x zoom mode.
You still can use it in non zoom mode, but shutter-times are not corresponding with the shutter-time settings on your top lcd display.

Yep, I know you said these are for x5 mode. I just though I would try them in FF mode as well.
I did notice that in x5 mode my lowest shutter was 1/33 and in FF mode it was 1/45, so it was changing between the two on the screen depending on the mode.

Ok, more pictures of interesting boring stuff. Earlier today I filmed 11 short clips, about 0.5-1 minute long. Camera got very warm, was showing 51C.

All had 2nd and 3rd frame corrupted, apart from one or two clips. The rest of the footage was fine.

All in 1632x2144 1x3 24fps preset. Some in full frame mode, some in x5 mode.

I was moving the camera around but chose the frames that would show the possible defects best, which means dark uniform areas.
All frames from different clips:




Just before I did another test. Filmed 4 longer clips. 8-13 min in length to push the camera further and see if there's accumulative effect Levas proposed. 2 were filmed in 1632x2144 1x3 24fps preset and the other two in 1632x2052 1x3 25fps. Basically, I filmed until my 128Gb card got full, which is about 35 min.

And still curious if the fix works when using the preset for longer times. Because before the fix it looked like the purple color shift in the right part of the frame was creeping in slowly over time using the preset. So needs some more testing.

I shot 11 short clips today outside and indoors. Took about 20 min, camera got pretty warm - 51C. Will post results later (have to go now), but in short - didn't find any weird stuff. Clips were shot with breaks. Do you want me to shoot continuous? For how long?

This seem to have fixed it.. Tried filming 2 short 1 minute videos. Same settings as before. 2nd and 3rd frames are corrupted, the rest is good. 1st did in FF mode the second in x5 zoom. The only difference noticed FF mode set exposure to 1/47. Same res as before.

Here are the shots from both takes:






Will do more testing a bit later.
Thank you Levas and Danne!

Ran some tests with the new crop_rec module. Can't see thin vertical stripes anymore but the thick pink area on the right is still there. Seem to be of random width, sometimes thinner, sometimes thicker. Same resolution 1264x2144 at 24f. Filming indoors (mostly carpet and walls) was getting 56mb/s continuous, pointing the camera outside from a balcony resulted in 65mb/s orange indicator continuous if pointing at low detail objects like houses and roads and which would immediately turn red if pointing at trees. So, it's right on the borderline of what 6D can record.

Here are the processed dng frames, all from different takes. The outdoor ones show the pink area in the shadows/dark places.










.. forgot to add- 2nd frame is dark/corrupted in all takes. In outdoors scenes the 3rd frame has some pink noise on top also, apart from this no corruption.

Just a real quick update..
A couple of short takes, 2 minutes each at 1264x2144 (for 16:9). Continuous, 57.5 Mb/s. Second frame is pink (normal for my cam), no corruption apart from that. But, noticed vertical lines in both takes, different patterns in each take. Here are screenshots from both videos:
