updated the first post on page 1 with the new crop_rec.mo download link & short tutorial video on how to enable the presets

#### Igor_Braun

Hi, Reddeercity!
I tested the new Crop_Rec.Mo and did some videos.
Everything is perfect, except that I couldn't get 3k 1:1 mode work the right way.
Mobile phone video:

Other moments:
* Is it possible to add 5k mode here to get all in 1 crop_rec.MO?
* Is it real to unsqueeze the 4k anamorphic preview somehow?
* I keep trying to get unfrozen preview somehow but only can get it in 14 bit... You already answered me on it, but I think it will be a good decision to figure out why there is a live preview in 14 bit mode, but not in 10 bit mode.

PS: sorry, had some unexpected things to do, so i did it only today.

Per my calculations, Centered 3.5k 1:1 (2784x1160 24fps) gives approx the crop of micro 4/3 on 50d.
Could someone confirm this?

I think I did the math right:
2784 x1160 pixels divided by 50D's 4752 x 3168 pixels = 0.5858585858

So if 50D has a 1.6x crop vs full frame, and then you divide 0.58585858 that's a 2.73x crop

A micro 4/3 crop is 2.0x. So the crop would be closer to a Sony 1" crop of 2.7

It depends , 50d does 3744x1080 So ......
5d2 crop_rec 2784x1160 , 5632/2784= 2.019 crop factor (18mmx12mm used of 36mmx24mm) of full frame
Micro 4/3rds , sensor (17mmx13mm) 2.11 crop factor or full frame
50D , sensor 22.3mmx14.9mm 1.6 crop factor of full frame , but in 3xcrop_mode you have 2000x1078 = (5.6mmx3.75mm used) 4752/2000 ->(2.37)+1.6=3.97 crop factor of full frame .
Though in Crop_Rec on 50D max res at the mount is 3744x1080 , so final crop factor changes to 4752/3744 = 1.2 crop factor + 1.6 crop factor of full frame = 2.8 crop factor .
So 22.3mmx14.9mm / 2.8 crop factor = 7.9mmx5.2mm used on 50D crop_rec .

So on the 5D2 center preset (2784x1160) (18mmx12mm) is just a bit bigger then 4/3rds sensors (17.3mmx13mm)
50D , 3xcrop_mode (3.97crop factor) (5.6mmx3.75mm) which is close to 1/2'' sensor (6.4mmx4.8mm)
50D , in crop_rec (2.8 crop_factor) (7.9mmx5.2mm) which close to 2/3'' sensor (8.8mmx6.6mm)

#### zcream

So far the center preset in only on 5d2. I forgot that part. If that works on 50d, it's about 2x crop.

This center preset (2784x1160). That's what I was referring to.

New updated 50D Crop_Rec
magiclantern-eXperimental-crop-rec_3.7k-1x1.11.30pm.2020Aug16.50D109.zip

magiclantern-eXperimental-crop-rec_3.7k-1x1.11.30pm.2020Aug16.50D109.zip

Updated the 50D Crop_Rec with new 5xZoom check (which enables crop_rec with out delay , same as the 5D2)
plus other back-end tweaks for 50D model .
Also has the updated mlv_rec module for increase resolution in non crop mode's as will as Crop_Rec.
3744x1080 before , now 3760x1080 .
I changed how to exit Crop_Rec , after you'er done recording press play button twice and you should exit cleanly to 3x3 from Crop_Rec.
If you don't and you just turn off crop_rec or raw video the camera will lockup and need a battery pull .

It's just got the one Crop_Rec Preset (3.5k Centered (3760x1080) for now , need some tester to make sure it works ok , once that's done I'll add more crop_rec preset .
Enjoy

#### reddeercity

Looks like Bitbucket has finally Delete Magic Lantern project,  all my download link & source files are broken/gone

I Hope @a1ex has got some place for Magic Lantern project so we can continue , or is this the end ?
I hope not , but there again nothing last forever .

Edit: I may have missed some links , so if you find any of my links are still broken please let me know .
So now i have no way of tracking downloads to know if anyone being testing/using the experimental crop_rec builds .
That part of my feedback , so i know the build is working as intended , since no one really gives feed back any more .
I can only assume by the download number that thinks are Ok . Now I'll have to guess

#### Skinny

I guess it means we have to report if everything is working as expected.. I usually download and test everything new for 5d2

@reddeercity

Thank you for your hard work.

Here is my feedbacks to the build-2020Aug16

1. Format CF card, it deletes the whole maigc lantern files.
old nightly build can restore back ML after card format.

2. No adtg.mo & cfacc.mo compared to previous build.
with crop mode on, I can record the 3760x1080, but no preview, whole screen with pink colour.
The video output also full of pink colour.

3. So I copy adtg.mo & cfacc.mo from previous built
Now I can record the 3760x1080 resolution, with zoomed in preview, no full size preview while recording.

4. With crop mode on, the 3760x1080 files, shows red pink bar on the right end, tiny pink line at the bottom.
black object/dark shadow with vertical lines. Black colour with colour cast.
---See attached file, extracted from MLVFS
M20-1619_000005.dng 3760x1080

5. With crop mode on, for other resolutions, tiny pink line at the bottom.
---See attached file, fifth frame from various resolution videos.
M20-1620_000005.dng 3520x1080
M20-1621_000005.dng 3200x1080
M20-1622_000005.dng 3008x1080
M20-1623_000005.dng 2880x1080
M20-1624_000005.dng 2560x1080
M20-1625_000005.dng 2240x1080

6. with crop mode off, no colour cast/ colour lines.
M20-1617_000005.dng 1584x892 no crop
M20-1618_000005.dng 2000x1078 crop

8. Is the extra 2pixels caused the bottom colour line?

Look, you can maybe use some online link trackers. I found this one:

#### SKecorius

How about making freely accessible (google docs) spread sheet, where everyone could put, which version he/she uses, what features are tested, what are the results, opinion, questions, requests, etc..?

#### T123

refer to my previous post,

we do not need to copy adtg.mo & cfacc.mo from other build, can just use the 2020Aug16 build.
The problem happened to me yesterday is due to the "fps override".
If i manually press on both the "fps override" and crope mode, problem happens.

the solution is, we do not need to manually on the "fps override".
It is already in 23.976 fps default in the build.

I like the google docs idea!

If you need storage space Reddeercity on Google drive I'll buy it for you! Google drive is pure gold honestly.

My earlier two posts are still waiting for approval..

@reddeercity
How do you activate 50D in 1x3 1376x1742 (4128x1742) @24fps ?
with anamorphic lens?

#### Igor_Braun

I think, that the google docs idea would be ok in the case of at least 2 or 3 developers. David now works alone on the developments of 5d2 and 50d. I don't think he would like to read every little thought came to our heads described in a sheet of google docs. Personally me, I wouldn't. It's more like hobby for him.

#### SKecorius

There is no need to read anything, if you do not want to. The numbers of people downloading 5DmII's code would reflect in the number of filled lines, which would not require too much attention..additionally, you would have information about tests in one place (e.g. card info, minutes recorded, max resolution, etc.). Perhaps after a while one could run some stats on the data gathered. To place 1 spread sheet file into Google drive is not that hard (also does not cost anything, as far as I know).

There are already google docs of ML (e.g. features, bitrates, supported cams, etc.). I do not know how frequently those are updated, or useful. Nevertheless, it could be a great tool providing feedback to developers.

Also, just downloads does not tell much.. Myself including, one might download ML build, but would not do anything with it. Then loose it (delete it, change pc, etc.) and download again, without putting it to test..(getting different camera). Spread sheet, on the other hand, would require active input from people actually testing the thing, and not just downloading.

#### dlprod

Sorry to come off like a dummy but how do I install the crop rec module?

#### Walter Schulz

Copy it to ML\modules\
just where the old one is located.

#### dlprod

Hi  I've done that but the module won't load on startup.  Is there a specific build I should be using?

#### yourboylloyd

use the build on the first post of this thread

#### dlprod

Full width 5.6k 16x9 A.R. , 4K Anamorphic 3x1, 1x3,  UHD 3K Plus 10-12bit Full HD?

then just drop the module in the modules folder correct?

#### dlprod

Never mind- got it working.
