in the process of moving right now , so all development  files are packed up , it was on bitbucket before they deleted it
Plus my FX pc mother board blow up , and it have all my files in a VM so it could be difficult getting them out of the old SSD .
Could be many mouths , not sure maybe fall .

GitHub is a better option than bitbucket.

From @reddeercity youtube channel 

Was there ever a clean 3200x1268 @ 23.976fps mode ? Thats closer to 16:9 than 3744x1080

Any chance of 2560x1440 ? Its less than 3.7k and its standard 1440p, hence more usable with other video footage.

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

Sent from my Lenovo TB-8703F using Tapatalk

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

Sent from my Lenovo TB-8703F using Tapatalk

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

In practice 1376 px out of 4128 px columns will give about 2.7k resolution (as row resolution is unchanged). However as you are squashing horizontal it is less noticeable.
It's great news however you look at it. This is closest to 4k dci we can have.

Looking like I'm very close to 1x3 (1376x1776) on the 50D some of the edges are a little jagged yet ,
my need a some more adtg_reg's like "adtg1[100c]"
but here's the first sample for the pixel peeper 


4128x1776_24fps_M25-0243_frame_3.png


1376x1776_M25-0243_frame_0.png

If any one what to try to get the same results here the reg's (note it takes time , and can't be rushed , adjust reg very slooooowly ) 


Edit: this is the max resolution for 1x3 @ 24fps ,
thou it is continuous recording @75MB/s , good that the 50D can record at 80MB/s 

This is great news. The Resolution is closer to 2.7k and the human eye is less sensitive to reducing horizontal resolution.
We used to have 1440x1080 and not many could discern the difference with 1920x1080

#1) yes 10bit  and maybe 12bit
#2) Yes in 3xcrop_mode , in 3x3 you can record 10bit 1856x1248 @23.976fps -- there no 1920x1080 in 3x3 or FHD (Full HD)
#3) there is no moire and aliasing in crop_mode it's 1:1 pixel no binding or line skipping . 3k is just a extension of 3x crop_mode.
#4) no , dual iso has been working on video for the last few years , I have a build on the first post of this thread that works with
all the crop_rec & non crop_rec video modes but it will not work on the nightly builds just my builds work with it  dual_iso_video_5D2.mo

#a) I use 64GB but I hear 128GB cards work on the 5D2
#b) I don't think it will ever make the nightly , it still needs lossless compression implemented (it's close but missing something to be full functional)
More then likely the preset crop_rec will be obsolete soon , it will be replace with a resolution base interface , meaning you can
select any resolution and it will pick the max frame rate for that size e.g. 5632x3744 =5fps or 3008x1080 = 24fps etc. .....   
#c) No , I have not plan to maintain the basic feature set unless there something I need for me (I shot news stories , short docs & the odd low budget feature films)
I only have plans to implement Lossless compression & CF Card interface over clocking ( for higher write speeds)
#d) yes , read the first post of this thread

#4b Is the current 10-bit and 12-bit video in 5d2 achieved without lossless compression? By truncated lower bits?

Hi. Just to confirm 3x3 mode on both cameras is still 14-bit hd right? We are using 10-bit and 12-bit for 3k and above..

Sent from my Redmi 4A using Tapatalk

No we need the higher write speed , compressed raw would give us (at .5 compression , which I read would the average)
from http://rawcalculator.netlify.com/calculator_desktop
basic 10bit just out of reach of cf/5d2-d4 cams

Code Select Expand


Resolution:2880x1080 10bit
Data rate:88.9MiB/s
Frame size:3.7MiB
Crop factor:1.96x crop
Field of view:20.8°
RECORD TIME: 5 minutes 43 seconds per 32GB card.

14bit compressed raw at .5 compression

Code Select Expand

Data rate:62.2MiB/s

So this would be the max if lossless worked on 5d2 , better crop factor

16x9 2880 with increased height & compressed raw , still out reach of the current CF D4 bandwidth (75-80MB/s)
need faster interface --  overclock the cf bus driver or find away to run cards at udm7 , theoretically @ umd7 the write speed should be 120-133MB/s

I prefer for more horizontal rez , thou there nothing wrong with increasing the height to the max .

This is what I'm hoping to reach as a goal for raw video , it could happen only with 2 things
compressed raw (.5) & faster UMD 6 ->7 & or overclock the cf interface on the write side

Code Select Expand


Resolution:3840x1556
Data rate:119.5MiB/s
Frame size:5MiB
Crop factor:1.47x crop
Field of view:27.5°

Now , I basic all this on continuous recording for raw video  @ 24p
If some user what to use the full width at lower frame rate with increase height at maybe 10 of 12 fps
for hyperlays etc... will that's great , so there's really should be no limit on resolutions just
limitations on the presets in the crop_rec.mo .

At least now I can say there's no more aliasing & moiré patterns 

I know this was an old post, but is there a possibility of overclock of CF interface? Something similar to sd_uhs for Eos m?

Looking forward to 1x1 2784x1160 on 50d. That is about the same as micro 43 crop due to lower Res sensor. I think FHD will be limited to 1600x1000 (approx) in 3x3 binning mode sadly.

I was thinking cineform raw. But that's not implemented. 10bit could work then.

Ignore the post. Won't work. My bad.

As a1ex wrote: Depends on scene. See
I suppose you can get 33% compression rate shooting white sheets at ISO 100...
Prove me wrong and show some footage with that ratio.

4096 x 1770 x 12 x 24 /8 = 249 MByte/s.
Pipe dream about required compression rate IMO.

Compressed dng is 3x compression. So you are looking at 81MB

Sent from my Lenovo TB-8703F using Tapatalk

4k (4096x1770) 12 bit lossless compression may be enough for the card speed limit. Fingers crossed

Something wrong with the test. 1160p seems softest of all 3. I think something in the brightness adjustment in post  made it softer.

sure , I'll let you know when it's ready

I'm going to clean up my 50d tonight ...wowowow.. I'm so excited about this

Sent from my Redmi 4A using Tapatalk

@reddeercity thanks for looking at 50d. Hopefully the compression module gets ported to raw_video_10bit_12bit_LVState
50d has less moire than 7d and 5dm2 so lots of potential..

Sent from my Redmi 4A using Tapatalk

Yes, works for me on 50D . I can zoom in, and record 2000x1078 rav video , zoom out and record 1584x1056 , both 12bit uncompressed and 24fps.
See screenshot of damaged frame - each zoomed clip has two damged frames at the beginnig, frame 002 and 003.
Magnification (5x 10x) is without pink hue, I have had using another build.

Any idea why 50d is not capable of 2.5k in zoom mode? Isn't the chipset similar to 7d and 5d2?

Sent from my Redmi 4A using Tapatalk

Thanks for the 50d check-in. I don't have access to my 50d ATM, could someone kindly test on the 50d..

Sent from my Lenovo TB-8703F using Tapatalk

Where can I find a recap post on 12 bit? I tried to look for it but didn't find it. I'm curious to know how much space is saved and if the image quality is really the same and only noise is taken out.

I hope someone digs up the 50d and tries 12-bit raw on it also. I cannot atm

Sent from my Lenovo TB-8703F using Tapatalk

Sad that everyone gave up on this cam. No more work on 10bit raw or hdr.

I'd say you'd be losing a lot if you sold your 5D3 for a 50D. You'd lose proper HD raw recording, 4K crop mode, good noise performance at higher isos, sound recording, and you'd gain aliasing and moire issues in their place. 2/10 would not recommend.

I remember an old build where dual ISO mode was enabled for video. Also, 2.5K in crop mode is possible with 10-bit/12-bit mode - hopefully that will be done soon-ish. No moire in crop mode...

@nikfreak Thanks.

The mapping from 14-bit to 10-bit is currently linear.

Here is the log mapping for SI-2K camera - output = Log base 90 (input*89+1).

> http://cineform.blogspot.in/2007/09/10-bit-log-vs-12-bit-linear.html

This is a pretty standard log profile that has LUTs for LOG to LIN conversion. Also does a better job with 10-bit RAW compared to linear.

@A1ex Any chance we can try get a log profile in here??
