Which post? It may refer to Canon's "crop" mode for  H.264 recording which was introduced with 600D.

I'm referring to this post: https://www.magiclantern.fm/forum/index.php?topic=17021.0

Yes, I just want to know whether Canon's "crop" mode for  H.264 recording in 600D record H264 video without pixel-binning like Crop_rec.mo is doing with RAW Video?

But in this post, it's mentioned that: Note that 600D and 70D already have this feature from Canon....
#3
Its already implemented by Canon in 600D?
Is that 3x and 10x zoom available in Video?
If so, does that mean I will get a crop video in 3x and 10x zoom mode without pixel binning?

Waiting for confirmation, thanks.

Raw Video / Re: Are these Focus dots?
August 04, 2018, 09:53:29 PM
Actually I sold my 600D and purchased 100D recently.
The 600D was limited to only 960x540 @ 14 bit.

The RAW Video of 100D after editing looks Gorgeous! (comparable to multi-thousand dollars Cinema Cameras) and thanks to MagicLantern Team for making it possible with $250 Camera.

I can't really express how excited I'm with the way you take MagicLantern to the new heights:
With 8/10/12/14 bit RAW Formats and that too with uncompressed and lossless options
With 2.5K,3K,4K recording options in crop mode (I'm able to record 2.5k continuously)
With SD Overclock Hack (I'm getting 67MB Write Speed even though 100D is limited to 40 MB)
Dual ISO, HDR Video ....and the list goes on.....

One more aspect that excites me most is the fact that I can record 2K or more RAW Video internally with a small DSLR Camera  compared to bulky Cinema Cameras that need big setups and rigs.

coming from 600D, after seeing those dots I thought that there is some Hardware problem in my Camera. I placed a question here just to confirm that. Even though focus pixels are coming in the way of RAW recording, you provided the solution to remove those dots to get clean footage.

Thanks to Danne and dfort for confirming and clarifying my doubts.

btw, I purchased Canon only because of MagicLantern and I think Canon should share profit with you guys!  :P (Seriously, you deserve it)

Thanks very much for confirming, Danne.  Really appreciate your fast response.

In MLVProducer, it looks like this:




Those dots disappear only when I select the "Remove focus dots" option in MLVProducer.  Like you said, it is confirmed that they are focus dots.


Is it possible to record RAW Video with-out focus dots like 600D?
Thanks.

That looks awesome.
I recently purchased 100D, which version of ML you are using....
Also, could you please provide a MLV sample file recorded using 100D?

Raw Video / Are these Focus dots?
August 04, 2018, 10:51:49 AM
Hi

I recorded ML Raw video using Canon 100D. When I open the MLV file in MLVAPP, I see the dots as shown in the image:



 
Please click on the thumbnail to view the image.

Although, the dots disappear when I select "Fix Focus Dots" /  "Fix Bad Pixels" / "Chroma Smooth 3x3" option in MLV APP.

This does happen with both 14-bit uncompressed and 14-bit lossless modules. I did not enable crop-rec 2k/2k/4k module.

ML version: magiclantern-Nightly.2018Jun30.100D101_2K-3K-4K.zip downloaded from https://bitbucket.org/Dannephoto/magic-lantern/downloads/

Can any one please confirm what kind of dots are they and is it possible to record ML RAW Video with out those dots?

btw, I didn't had this issue when I used to record using 600D in legacy RAW format...

Thanks

If you want to go with debayering a single image then the following algorithms seems to be good....

Self-similarity Driven Demosaicking  (BCMS-SSDD). Info: http://www.ipol.im/pub/art/2011/bcms-ssdd/
Directional Filtering and a posteriori Decision (DFPD). Info: http://blog.cuvilib.com/2014/06/12/dfpd-debayer-on-gpu/

Welcome!

I would disagree with you. Dual-ISO reachs 14 f-stop DR. This is near or more than the most expensive cameras out there can do right now (there's lots of other issues, of course, such as aliasing). If this is right, BMPCC is only 0.5 stops better with normal iso. With the ADTG research Canon cameras could supersede that 0.5 stops (current gains on MKIII seems to be around 0.8 stops, so 0.2 better).
Also, BMPCC has a smaller sensor, compared to Full-Frame sensor of 5D's.

Besides high-end cameras from Arri, Red and Sony, I seriously think 5DMKIII is the best choice. Of course, it doesn't have PL mount and other stuff but the quality is very good.


I will try that. I have not used the Dual-ISO feature yet.

I'm from Andhra Pradesh. Yes, crop factor of 2.88x and many other drawbacks.....
I stick with Canon 600D because I want a camera that captures both photos and videos.

The technique you have posted is called "Pixel Shift" technique.
Currently, some cameras like Pentax K1 implemented this, but it is only useful for shooting static objects.
Accurate implementation of "Pixel Shift" technique is not possible via software (afaik).
However, Super Resolution technique stated on the page creates a sharp image with higher details but that too needs several shots....

Also, Sigma cameras uses "Foveon multi-layer sensor design" that uses three layers one for Red, one for Green, and one for blue. So, there is no need for interpolation.

Hi

I'm from India. I'm a big fan of ML. My Most favorite feature in ML is RAW video.

I don't know why but the colors of ML RAW videos looks better to me than Black Magic Pocket Cinema Camera. Though, Black Magic Pocket Cinema Camera beats every Canon Camera when it comes to dynamic range.....

Yes, even without crop recording , its No. 2 camera for ML-RAW video because of its buffer speed.
Crop Mode only good for 10/12 bit and and if you need 14 bit RAW, then one should overclock the card....
#17
Does 7D support ML RAW  Video, why is it marked in red?
