General Development / Re: Ultrafast framed preview (5D3)

When you say 12bits and 14bits, you mean 14bit and 12bit lossless? On my 5d3, with all the hacks active, sd overclock, audio off, etc I can't record more than few seconds if I use a non lossless bit depth. Am I doing something wrong?

Yes, he means 12 and 14bit lossless 😉
Just use the bitdepth in the Movie Tab - it is all lossless and a tweaking from the 14bit lossless. Just let the data format in raw video at 14bit lossless.

Change "Kill global draw" to off

Thanks for reply. I tested it again and all problems are gone 🤔... Only 2 times i hang in crop preview (from maybe 20 times), and i can't also reproduce it. But after refreshing live view, all works again (double press menu).

I think i need more testing 😅
#4
I've tested it and it works very well, good job.
It's nice to see that things keep progressing.

But with some side effects/ problems:

- If i use grayscale preview, i can't switch back from crop preview if i press half shutter or star button for focusing for example

- (Raw)Zebras don't hide while record now (I set hide while record, but it has no effect) -> i need to disable it manually everytime

- write speed with ultrafast grayscale is lower now i think-> is it possible to set the colored preview only without changing grayscale while recording?

I don't testing Play preview or have the raw data checked for errors....
#6
Just "kill global draw" and you can continuous recording at 7.4fps, at AR 16:9. (Broken preview while recording)
#7
Have you just tried to turn audio off (disable) with 7.4fps at for example AR 16:9?
#8
Is there a way to turn off bitdepth reset while camera starting?
I personally use crop rec only, but if I start the Camera in Photo mode, the bitdepth setting will reset almost every time, while sd overclocking process. I know you have Implemented this for 3x3.

Hi, sometimes when using "one more hack" the console shows

Is there any way i can remove the console? (not the "Show console: off" but deleting the console or maybe even just ignoring it so i can see what i'm recording without the console in front of it)

If the console shows, it means there is a Failure somewhere. I have this sometimes too, deleting the last clip (because of corruption) and restart Camera is the best way.
Maybe you can read the failure message next time, maybe it is helpful for bug fixing.
#10
Sry, but I don't know how this works. But I'm mean "deleting from disk", maybe this will helps.
#11
There is maybe a problem with deleting cardspanning Raw files. In my Case MLVapp crashes and delete only one file (MLV file, not the second).

Tested on Windows.

Cool, what CF card are you using? mind running CF card benchmarks in Photo mode?

A Kingston Canvas 128gb (not the fastest, but cheap) - > benchmark CF only: 115W, 146R

But I tested my Komputerbay 128gb now too. I reached unbelievable 156mb/s - > ~7848mb / 1203 frames x 23.976 = ~156 (after 40s stopped automatically) - > Benchmark CF only 119W, 152R
Benchmark CF + SD: 155W

But there is no change in Benchmark with and without your hacks.

QuoteI will make more tests on 5D3 in future and will see if I can reproduce your issue too.

I think the shut down problem was the Battery itself, maybe not full recharged or something.

Thanks for reporting this, and for testing.
I might take a look later into shutter fine tuning with these hacks, and will see if can do something about it.

149 MB/s is probably not real, unless you are using lower FPS, which mode you are using?

3.5K Preset in 3584x1730, at 23.976fps at 14bit lossless. With your Hacks, SD Overclocking and card spanning. Filming static scene.
I double checked the filezise on my computer. mb / frames x 23.976.

Without your hacks I reached up to 139mb in my older tests


Sometimes the first frame is corrupt but the rest is good.

But I think this writespeed is really bleeding edge: If I use raw zebras histogram and waveform (with Kill global draw), the record stops automatically after a while (also with green indicator), camera shutdown and say Battery low. With dummy Battery it stops, but without shutdown. And without waveform it works fine (with Battery) .

@theBilalFakhouri

I tested your build with my 5DIII, but I see a problem:

If I enable aewb and I record a underexposed scene, it changed exposure while recording - > lighten it up. It is visible in ML app too, but I can't see change settings.

EDIT:
I found the problem... This is only happen if you use shutter fine tuning too.

EDIT2:
I reached a write speed of 149mb/s.
I stopped manually after 1 min. (orange indicator)

Nice Job!

Raw Video / Re: AI algorithms for debinning

Interesting discussion ;)

Btw, the maximum writespeed on the 5D Mark III is not 135mb/s. The edge is somewhere else.
In my Tests I got 138mb/s and I wrote this in the Forum here.
https://www.magiclantern.fm/forum/index.php?topic=23041.msg230881#msg230881

But later I reached 139mb/s, but never more.
I reached this with the 3.5K Preset in 3584x1730, 23,976fps at 10bit lossless (tweaking from 14bit lossless) and with cardspanning, sd overclocking 160mhz and kill global draw (5x crop preview).
I stopped manually;) and this is not a high peek Number, this is a average number -> I double checked this on the computer.

Hi, some short answers :

- full resolution LV is only possible with audio off and global draw off or kill global draw
- Aspect Ratio: you can change it and get in Anamorphic mode (set to off) full 1920 streched to 5.7K and for example 3.3K, 16:9 and 3.5K nearly 2:1
- continously recording: for better Result you can decrease bitdepth. Default is off - > meaning 14bit lossless, try 12 or 10 bit (all lossless), And if you set global draw off increase writespeed, but preview is only available in 3.3K and 3.5K mode - >5x zoomed crop live preview.
- SD overclocking works only with SD Card
- With Cardspaning: I did a lot of tests and the showing Writespeed is not correct

14bit lossless is the best option. The first bitdepth setting (8, 10, 12, off(14)) is just a tweaking from 14bit lossless. Or in other words all are lossless.
With 10bit (lossless)  you can record continuously in all condition and with 12bit sometimes too (depending on scene).
#18
QuoteI found higher resolutions stopping recording early when using sd overclock/card spanning.

I can record continuously at full 3.5K.

Have you tryed different bitdepth (10 or 12 bit)? Which SD card do you use?
I recommend SanDisk Extreme Pro 170MB/s 128gb. Have you tryed record without global draw (kill global draw or off)?

Maybe some more information can help us: Camera, settings, ML Version...

There is no blacklevel problem.

In your Receipt your gamma is set to 1 ,don't know why this happen.

QuoteWhat about the 8k on YouTube?
Why you want upscale this? In my tests I upload a 5.7K video and I can set to 5K in the web browser and if I click right click on statistics, you can read this is 5.7K ;)
In my opinion there is no reason for upscale a 5.7K Anamorphic image.

The only reason is with footage less than 4K, but not for quality of the footage, just only for Youtube - > YouTube HD quality is really bad.

Oki. From what you describe it seems related to card spanning. If possible do more tests without card spanning.

I tested some multiple recording delay tests with cardspanning and without (2sec. clips) and the result is: No failure in wihout cardspanning, but i found another interesting thing.
In the cardspanning tests: After a clip without audio, the next clip was only recordet on CF card and this clip is about 900mb bigger  (~300mb vs 1250mb). But the clip before has the same filesize (~150mb)

here 3 files example:
1. with audio, 2. wihout audio 3. bigger size and with audio

https://drive.google.com/folderview?id=1pLemHSb2UynLEkaIJuNA7eIHmKYzDrDJ


I also tested without SD overclocking -> same result. There are also 3 times without audio behind each other -> all 3 clips after the first clip without audio are much bigger and the first 2 without audio, but this time there is a 1kb file on the SD Card (from the 2 bigger files without audio).

I hope this will help.

-------------------
Edit: files are bigger because more frames...

Checking metadata:
File Header (MLVI)
    Size        : 0x00000034
    Ver         : v2.0
    GUID        : 17047428700475394385
    FPS         : 23.976000
    File        : 0 / 0
    Frames Video: 132
    Frames Audio: 0
    Class Video : 0x00000021
    Class Audio : 0x00000001


Frames Audio: 0 so I guess something would not allow wav file to be recorded. Is this reproducable? Only happening in 3.5k mode?

Not really. In my Files i have no audio in 0% up to 33% of shoot sessions. And this is not only in 3.5K, in UHD 1x1 and 3.3K (16:9) is the same problem, but not so often i think. I delet some older clips, so i can't see older tests with Anamorphic. But in all records i use cardspanning + sd overclocking.
I think i need some systematic tests (camera on, record and stop, changing bitdepth, record and stop, changing bitdepth, refresh liveview, record and stop, focusing, record and stop, 10x zoom, record and stop and so...)

OK, in 8min there is a 600mb clip online. Same Link

Could you upload one recording with missing audio? There are more than one way to develop footage that could solve this. Most likely audio is still there.

I have this problem sometimes too, here is an shortend example:
