General Development / Re: Dealing with Focus Pixels in raw video

@dfort:

I've just tested, chroma smoothing do not do much about that artifacts on the white car it seems.

Nothing: https://picload.org/image/rgcaadrl/nofix.png

@indra, hello:) I installed ML a week ago, it's blowing my mind! I would encourage you to test the new MLV raw format instead of the legacy RAW. I also get the flickering of the screen, a fraction of a second every five seconds or so, while navigating the ML menu. Not disturbing once I got used to it.

Another little thing, although I do not know if it is 100D specific, or if I could fix the layout myself in some menu: the histogram and DOF info together are overlapping a little bit and flickering, one over each other:



Update on the tested stuff:

ML menu: flickering of the screen, a fraction of a second every five seconds or so, while navigating it.

Modules tested:
arkanoid: OK
bench: OK
ettr: OK
mlv_rec: OK, but 23.976 fps recorded as 23.972 according to MLVFS
raw_rec: OK

Expo:
Auto ETTR : OK

Overlay:
Zebras: OK
Magic Zoom: OK
Cropmarks: OK
Histogram: OK, overlapping and flickering with DOF info
Waveform: OK
Vectorscope: OK

Focus:
Follow focus, arrows : OK
Rack focus: OK
DOF info in LiveView: OK, overlapping and flickering with Histogram

Movie:
Crop mode: OK
RAW video (MLV): OK up to 1440×602@25fps

@Frank7D, dfort, DeafEyeJedi

Thank you for your analysis. Crop mode does help a lot, but indeed this mode can't be used all the time. I'll test chroma smoothing on the white car this week.

A comparison from my first raw video (posted in the "Share Your Videos" thread) is provided below, normal first, crop mode below. DNGs from MLVFS are imported directly in PP, with a basic grading using a LUT, only with exposure, highlights, shadows, blacks and whites.

There also a disturbing irisation on the rocks (last pic). To my untrained eyes it does not look like focus pixels nor aliasing. What do you think?

This is my first test of ML raw "in the wild". It's really amazing! My intend was to play with rack focus, and there I discovered the power of magic zoom.

Basic grading in PP using only exposure, highlights, shadows, blacks and whites.

Raw Video / Re: Canon 100D RAW Workflow
« on: May 19, 2016, 11:28:38 PM »
For the frame rate, I tested 23.976 (by selecting 1080p24 in Canon settings), but MLVFS reports the recorded footage to be at a weird 23.972, so I'm getting back to good ol' 25. I could test the FPS override setting in ML, though.

At 1280x720, recording flag stays yellow, so I guess that means I'm losing some frames. Now I go with 1440x602 (a ratio of 2.39, which is a popular ratio in movie theaters nowadays, and still often referred inaccurately as 2.35). With this setting, the recording flag becomes green after 15 or 20 seconds of recording.

Two years ago, I shot in H264 1280x720 at 50 fps, because I wanted to do some slow motion, but I guess you wanna talk about high fps with raw recording? Then in order to do that 50 fps, I guess one would have to lower the resolution, the limiting factor being the SD card writing speed. E.g. my 1440x602 would become 1024x428 or 992x416.

Upscaling does not seem to be a good practice to me.

OK, solved! "Run as Admin" cmd is mandatory in order to get all the dots away with nothing turned on.

I still get some artifacts on the white cars and power cables I can't seem to get rid of, is there anything I can do about that?

Thanks for the pointers!

If I summarize what I've learned so far:

1. MLVFS (which btw should be able to get rid of those annoying dots I still get… I posted about that issue)
2. AE via this script downloaded here: http://www.alexandsteffen.com/smartimport2.zip
   In ACR :
   WB, most important (I use a blank, grey and black card when shooting)
   Chromatic aberration lens correction
   Exposure / Highlights defringing if needed
   Sharpening/Noise reduction if needed
   Apply VisionLog Profile (Maybe I will get Cinelog when I will be more experienced)
   Then render to DNxHD
3. PP: organize, edit, then apply VisionLOG to Rec.709 LUT to get a neutral image, then another LUT to go from Rec.709 to, e.g., a film look (not sure about this step, though)

Oh! Too bad… Yes, in the provided "nofix.png" picture, nothing is turned on, using the mounted MLV.

I use a fresh Windows 10 Pro with Dokan 0.8.0 (redist version). I copied the directory containing all the unzipped files of "MLVFS_x86.zip" in "c:\Program Files (x86)". The user (me) executing mlvfs.exe is admin class, as it seemed to work, but cmd itself is "not run as admin". I run mlvfs.exe in this directory.

Code: [Select]
mlvfs.exe d:\mnt --mlv_dir=d:\mlv
Am I doing something that can cause the malfunction? What can I test that might help?

Hi, I have a 100D/SL1, and by default the raw video is unusable, with a pattern that resembles the one described earlier in this thread.

Thanks to your amazing work, using MLVFS, almost all of these evil dots are gone, and the footages are now so much better. However, I still have some dots left (the most obvious is two lines near up and down) are some artifacts. I wonder if I'm the only one, or if this is a problem that you are aware about.

Here is an example of a 1440×602 raw video, with various settings enabled. I don't know in if I was in mv1080, mv1080crop. The only modified settings is RAW VIDEO, 1440×602.

No fix at all : https://picload.org/image/rglowipw/nofix.png

Raw Video / Re: Canon 100D RAW Workflow

Just beginning to find a workflow for awesome raw video with the 100D/SL1.

This afternoon I installed ML for the first time, and recorded my first MLV, continuous 1376×576 at 25 frames/s

I tried MlRawViewer, I didn't get it to work. Next I tried MLVFS (http://www.magiclantern.fm/forum/index.php?topic=13152.0). It works very well with Premiere Pro, which recognizes this CinemaDNG format.

I want to take advantage of RAW editing, either with Lightroom or Photoshop. None of those deals with CinemaDNG, DNG is OK of course. But now the major drawback is that it seems that MLVFS is read-only, so I can't write the DNGs :(

Hi, so exited about raw video and many other stuff :)

I just installed it, 100A didn't work, but 100B did.

bench : OK
Card and memory benchmarks works (write speed is good, up to 43.2 MB/s with a 32 GB SanDisk Extreme SDHC I 45 MB/s)
arkanoid: OK
raw_rec: OK
mlv_rec: OK
Both modules are producing files, respectively RAW and MLV, but right now I didn't find a tool that works to convert them (tested MlRawViewer, will search the site for alternatives)

Thanks so much for this port!

Hi everyone,

I'm very glad to be here, and very exited to see a lot of activity around the Canon 100D port, which now in beta. I'm doing photo and video for fun, and I'm looking forward to record raw video, use the intervalometer, and the focus features that ML provides!

Cheers!
