ArcziPL's crop_rec_4k experiments for 70D

[zhuzhixun521]

My 70D USES magiclantern- crop_rec_4k_70d_crop_rec_mo.2019mar29.70d112.Cannot use MLV _lite.The clear button cannot be used to trigger the ML menu when entering movie mode.MLV_rec is normal.Sorry, English is not my native language, maybe I didn't express it accurately enough

[Vy7ka]

Thanks a1ex once again. Your knowlegde is amazing.

Tested:
- 1832x1024 resolution 24&25fps: works
- 720p 50fps: works
- full-frame mode: works
- 3x crop mode (this model has it available as option in the Canon menu): works
- audio: works
- Servo-AF: works
- Single-shot-AF (triggered with half-shutter): works (if small hacks disabled)
- 14-bit lossless: works
- 12-bit lossless: works
- 8..11-bit lossless: works

All in all it looks very promising already. Here a build, so you can use and test it as well. Please feedback.

https://bitbucket.org/ArcziPL/magic-lantern/downloads/magiclantern-Nightly.2019Mar07.70D112_crop_rec_4k_mlv_lite_lossless.zip

This build
- is based on crop_rec_4k_mlv_lite_snd
- does include a custom variation of sd_uhs module: only one setting is used, benchmark is run once upon activation
- uses #undef FEATURE_ARROW_SHORTCUTS, so this feature won't pop-up unexpectedly in LV
- doesn't include dualiso module, as my cam uses alternative adresses of some registers and I've adapted it already. If you need it, take it from any other working build.

Hey yall, haven't checked forums in ages, used old build of ML, used MLrawviewer and was quite happy with quality of recordings. Shot 1600x900 MLV raw video, stretched to 1080p and that was that. Now I found your ridiculously awesome build and was blown away by what I found. Different bitrates! Now im shooting at even higher resolution for 30s using 10bpp. 30 seconds instead of 13. And I didnt see much of a drop in quality, but I guess that would stand out in post processing. Also, tried mlv_snd, which also helps. And 60fps. It only shoots for 11 seconds for my desired resolution of 900p, but man. I wanted to upgrade to sony a7 just for slow mo footage, but now it seems, I can stay with my beloved 70D longer. It's currently 2am in my timezone and I'm just as happy as when I got my camera.

I expect a shoot next next week and this upgrade is just what I needed.
Need a bit more testing, if I find time ill do just that.

Try 14bit or 12bit lossless raw instead of 10bit. You wil be able to record continous.
You can shoot 2.5k continous in 5X with the ush_sd hack

      @ Andy KH

   Would You Please provide info on which build You use & Detailed Settings

to get "2.5k continous in 5X with the ush_sd hack" ~

                     ORR ~ DeanB

[andy kh]

As of now i hv two builds in two different cards. One is build by Arczipl. This build doesnt seem to work the uhs sd hack in my initial test so i replace with danne's ush sd hack that run with lua script. It give me about 58mb/s write speed

And one important thing is setting the fps override to your desired fps is little tricky in 70D. You cant increase but decrease. After setting the desired fps, i need to adjust it wit timer A otherwise it wil keep jumping to original every few seconds.
I have another build by danne but i need to do more test for this build

[OlRivrRat]

Details Please > Build Names & Dates. Also What Settings. Thank You .

My settings are 12bit or 11bit lossless@ 23.989 with uhs sd hack enable and i dont use the sd uhs hack from this build.
As i have mention fps override is little tricky you need to adjust with timer A. I wil try to make a video tutorial tomorow as im away from home atm

@ Andy

Thanks a bunch, I'll pay attention tomorrow.

   Just tried "crop_rec_4k_mlv_snd_isogain_1x3_presets_2019May12.70D112", Only Rec's less than 1sec >

SDCard Bench Test shows around 19MB/s, Write & Errors, Read ~

[andy kh]

@OlRivrRat these are my settings. i can go little higher than 2.5k and shoot continous
just to show you i recorded for 10 mins
i have to turn off crop rec in modules otherwise i always get realtime preview

I tried Andy build see May 12th post, reply3342


Not able to get steady 23.9 fps.  I put it in 1080 fps 30 and 5X, and try to fps override, but it jumps around 29.9. 
  What val for timer A? and Timer B? to prevent?

I was getting fast rise in cpu from 41degress to 50 degrees, at 2.5k aspect 2:35.1 and 29.9fps flcikering

- which modules loaded(mlv_lite,_rec_play_snd, file_manager, crop_rec, and uhs_sd???)

In general how does one ensure fps override is on menu??? It seems I lose it from menu???

[andy kh]

another example of 2.8k continous 10bits lossless 23.989fps

[ShootMeAlready]

There seems to be a disconnect here. Walter is saying dont fps override, and Andy is doing it to get 2.5k continuous @2:35.1 with 5X.  Am I missing something?

The fps at 30, happens automatically whenever you select 5X. 
So clearly Andy has a trick to get the fps on menu & adjusted back to 23.9 fps.
Whats up wid that?

[Danne]

Think he goes into advanced and change the A-timer. Try that.

[andy kh]

Think he goes into advanced and change the A-timer. Try that.

yeah danne is right. you can lower to any fps by changing the timer A

i wish timer B also works

[ArcziPL]

As of now i hv two builds in two different cards. One is build by Arczipl. This build doesnt seem to work the uhs sd hack in my initial test so i replace with danne's ush sd hack that run with lua script.

It works for me flawless. What do you do exactly?

You have to go to Debug menu and activate it manually. Combining my build with Dannes autorun script won't work out of the box, as they were not meant to work together. However, you can adapt the script easily -> just replace the menu option name "MAY CAUSE DATA LOSS" with "160MHz fixed". That's what appears in the menu, to easily distinguish which version is loaded.

[andy kh]

@Arczipl  i did exactly wat you said but it didnt work. I think it crash twice if i remember
I replace the uhs sd and the lua in modules and add his script and it works flawlessly. I need not activate manually everythime i start my camera

[ShootMeAlready]

I only find fps override on exper build,
magiclantern-Nightly.2019Mar15.70D112_crop_rec_4k_mlv_lite_lossless_fps_override_experimental

The problem is that at 2.5k it only runs for 5s, or 150 frames.  There is no overclocking to change the write speed. Also the Timer , will not take 5X back to 23.9 fps.

So what gives?

you read what ArcziPL just said. you have to go to debug in Ml menu scroll down...
you wil see something like this  "MAY CAUSE DATA LOSS" with "160MHz fixed
press ok to activate.

[andy kh]

to change the write speed. Also the Timer , will not take 5X back to 23.9 fps.

first go to 5X and set to your desired fps

Using "magiclantern-Nightly.2019Mar15.70D112_crop_rec_4k_mlv_lite_lossless_fps_override_experimental"

Was able to get 2560 @ 2.35.1 23.9p 12bit raw lossless continuous in 5X.  Global was off, generally.  Very slow playback.

Was able to get 1920 @ 2.35.1 59.9p 12bit raw lossless continuous in 5X.  Global was off, generally.  Extremely slow playback (1minute clip takes about 5 minutes). 

In 5X you only have centre box focus, no facial recog., Without focus peaks it brings into question MF choices. But the picture is gorgeous in detail and depth, it feels like the LCD is maxed out.

I notice it showed centre for box location (5X), but it was actually off to the right third of full screen (1X). 

If you put global back on, screen loads up with "fix me: malloc errors", and even more if you keep pressing buttons to virtually entire screen.

To make this practical, need global on with rgb & focus peaks and ofcourse errors disabled. The playback needs to occur much faster else 60p is too painful.

Also with 5X my Tokina 11-16mm 2.8 starts to become the goto lens. Ok 18mm on the Sigma 18-35mm never sucks either, its just 5X is a lot.

3X mode with 1864 @ 2.35.1 23.9p 12bit raw lossless continuous, this mode has no moire and will also work same for 60p. 3X loses the AF features. 

In regular 1X, 1832 @ 16.9 23.9p 14bit lossless continuous, this mode has full AF capabilities touch screen focus. (the  60p of same is probably continuous I stopped it after 34s but should test to see if it keeps going to say a minute).  The picture is gorgeous, and uses most of the LCD screen.  This mode is rather sexy and for most straightforward shooting a useful mode, having near 1080p @ 16.9 24 to 60p, in 14bit raw lessens my 5DIII desire.  This closest to a broadcast TV quality picture (its not quite 1080p resolution but exceeds TV colour of 10bit).

i dont think you can shoot 60fps in 5X mode. no matter whatever your setting is in canon menu when u zoom in 5X it wil change to 30fps
