« on: February 04, 2023, 12:15:59 PM »

Hi everyone, here is a small review of Helios 44M and some footage that was shot in september

By the way, is it too saturated? Unfortunately we only have a laptop with a *very* poor screen and no way to check on any decent monitor for now..

I always use 12 bits (with 5D2) and the only difference is *slightly* more noise in shadows, but there is almost no difference really. For example, 10 bits are 10 times worse. But 12 are fine for me... saves some card space.

Maybe.. good point. Then it is better to just hide everything if possible.

I am not that experienced with this whole.. thing. For example in my case, they just took me to the special room like the ones you usually see in the movies.. with fences everywhere and locking doors. Asked a lot of questions for ~30 minutes. I knew it was only for psychological pressure because I heard other guys stories. But the whole bus was waiting for me, and I was afraid that it will leave.. but luckily, the driver understood the situation and other people were also supportive

I think an option to turn the display 90 and 180 degrees as well as mirroring it could be useful in some situations.. What about RAW recording while using your app?

Actually I thought about this feature
I crossed the border recently, and was interrogated. Nothing serious and luckily they didn't check my camera. There were some videos where I say things against our fascist government So if you could for example encrypt video in camera, after filming.. even if it is slow. It could be useful.

Maybe even the option to hide videos from camera (like change file extension) so they won't play - can already help in many cases.
Or a password for the camera, with "wrong" password which will trigger a card format, hehe

when activate it the clip will darken, sometimes underexposure. In this case I just increase the light strength Lighten to around 70.

If you want to have the exact look as it was before checking "creative adjustments", just reduce dark strength to zero. It will look exactly the same 

I even think dark strength should be set to zero by default with log C, so people can do adjustments easily if they want to.. But it is just my opinion

I found that if you use CA desaturation in mlv app - sometimes the footage may begin to look like it was denoised or compressed to some very crappy quality... so I almost never use it, except when it is really necessary.

In this example in your NLE you can easily use color replacement tool or something like that, select for example this dark green color (use color picker), and desaturate it or change it to the color of paper. Use mask to select problematic area (for example, this book) so you won't change colors in other areas of your image.. it is relatively easy.


By the way, I like the look of your video, how you color grade it?

Raw Video Postprocessing / Re: MLV App 1.14 - All in one MLV Video Post Processing App [Windows, Mac and Linux]

« on: September 18, 2022, 12:54:00 PM »

I often use 30 fps and export at 24 to create just a little slowmotion.

The problems are almost unnoticeable, sometimes I see frame tearing or slight stutter. You can barely notice it.
It is not only on my devices, for example https://www.avsforum.com/threads/fixed-apple-tv-4k-lacks-support-for-24-000-video.2961262/

So as far as I know, most consumer devices were made for 23,976 and not for true 24. Of course they can play 24 but it is not their native framerate. They usually have only one clock generator and it can't support both, so manufacturers choose 23,976 because it is more common. As well as 29,97 and 59,94 instead of 30 and 60...

Some info explained here https://github.com/mpv-player/mpv/wiki/Display-synchronization
They have to invent a lot of stuff to deal with this small difference between framerates..

And from what I see, it is just better to stick with 23,976 for the internet. But for now MLV App can only export at 23,976000 and not at 23,976024.
I don't really know if it should be exactly 23,976024. Or should it actually be 24 * 1000 / 1001 ?
I hope someone can clarify all this stuff..

« on: September 17, 2022, 05:39:40 PM »

Probably noob question, but.. what framerate should I set on export?
I read somewhere that most consumer devices can't play exactly 24 fps smoothly, they are made for 23,976.. and for example my monitor has 59.9hz instead of 60. It seems like clips with 23,976 fps (from camera standard .mov) play better, no tearing artefacts or stuck frames. While 24 fps exported from MLV App have such problems sometimes (on my computer at least).

Should I export to 23,976 to maximize compatibility?
And there is a problem, with standard .mov files from camera I can see framerate: 23.976024
If I export with MLV App I can only set 23,976 and it will be 23.976000

Is it not standard? will services like youtube transcode the file and change framerate to 23.976024? Maybe we need a preset for exporting 23.976024?

General Chat / Re: Brainstorming features for a PTP/USB/IP Android App

« on: September 16, 2022, 09:41:46 AM »

I think it is a great idea. If you can make DSLR controller compatible with ML - it can replace hdmi monitors and remote control.

For extra features...

• An option to see clearly if something is connected to the USB and if DSLR is detected, etc. so - detailed status information. Because with existing android apps it is really hard to tell if everything is connected and why it doesn't work sometimes.. Especially if I'm trying to use long cables and so on.
• And if connection with the camera is lost, reconnect everything automatically..
• Probably at least some compatibility with ML raw..
• It could be very cool if the app can trick the phone to think that the DSLR is one of built-in android cameras, if it is possible at all. With this option it will be very fast and easy to take a picture with DSLR and immediately upload it on social media such an instagram for example, without saving and transfering the file. Like it is native phone camera.

Raw Video / Re: Canon t2i 12bit or 10bit?

« on: September 12, 2022, 06:39:25 PM »

This build almost works
12 bit ok, but 10 - top 1/3 part of a frame shifts out of place all the time, so the image is broken. It behaves differently with FPS changes, so... I don't know Some registers values are not right?

For me 10 bits makes a lot of difference. For example, 1600x670 using 14 bits I can only record for 4 seconds, using 10 bits - for 8 seconds.
If this time could be increased to ~10...12 sec for me it can be enough to actually use RAW on this camera..

More info: i use ML version: crop_rec-4k3x1-2.8k24p_3x3-48p-all-centered_8.18pm-5D2-eXperimental.2019Dec31.5D2212, and duplicate that for all CF cards (because i want to record 10 bit MLV not 12bit it is too much)

Using this build, sometimes when I turn on the camera ML modules won't load and files in "modules" folder gets damaged - they have random (garbage) file names and I can't even delete them. So then I have to format the card. Maybe this behavior responsible for your cards failure...
You can try this build
https://builds.magiclantern.fm/jenkins/job/raw_video_10bit_12bit/53/artifact/platform/5D2.212/magiclantern-raw_video_10bit_12bit.2019Mar24.5D2212.zip
form here https://builds.magiclantern.fm/experiments.html
It has 10 bit option and so far I haven't encountered this error with this build.

General Help Q&A / Re: Need to record video at 5X magnification

« on: September 02, 2022, 09:25:51 AM »

Raw should probably consume more power. But when I did timelapses with 550D, I didn't notice much difference between usual h264 and raw.

64bit version won't be much quicker than 32bit, it is just the way MLV App work. It does all calculations with CPU and processing raw video takes some time. If you have fast computer you can open two or more MLV App instances and process multiple files at the same time.

If you want speed - you can export dng sequence from MLV App (it will be relatively fast) and then open it in DaVinci Resolve.
Also check this https://www.magiclantern.fm/forum/index.php?topic=19021.msg239749;topicseen#msg239749 it can process raw footage with GPU and it is fast but you need a powerful GPU.

For instant .mlv playing you can check this thread https://www.magiclantern.fm/forum/index.php?topic=26596.0 and other links in it.

if resolution and quality is not important, you can use 640x480 crop from Canon menu, it is default 550D option. It will give you maybe even more than 5x magnification..

Raw Video / Re: What are you using to play mlv?

« on: August 30, 2022, 06:54:05 PM »

On windows 10, ffplay.exe and MPV player both works, tested them with 5D2 and 550D uncompressed mlv files, 10/12/14 bit depth - all works. I don't have any MLVs with sound so didn't tested it..

MPV player seems to work more smoothly, and it loads relatively fast, I associated .MLV with it - cool. But as you know - videos look green, so I made a quick lut (could be better) and spent a lot of hours trying to figure out how to make it work...

First of all, if path to the LUT file contains drive letter, for example  -vf lut3d=C:/dir/lut.cube - this will not work, at least on windows 10. You should write it like this:

Code: [Select]

--vf=lavfi=[lut3d='C\:/mpv/correction.cube']
where C:/mpv/correction.cube is your path to the lut. Notice \ before : and single quotes ' - it is important.

Then to pass this argument while opening .mlv by double click, I wrote a batch script but it takes extra couple of seconds to execute, so it is not optimal.
I ended up modifying the registry, seems like in windows 10 they changed everything and I could not find how to add a parameter to .mlv, so I just edited registry for mpv.exe

in  \HKEY_CURRENT_USER\SOFTWARE\Classes\Applications\mpv.exe\shell\open\command
it was:
"C:\mpv\mpv.exe" "%1"
I changed it to:
"C:\mpv\mpv.exe" "--vf=lavfi=[lut3d='C\:/mpv/correction.cube']" "%1"

Now any file opened with MPV player will play with LUT, but if we are only using MPV for MLVs it is fine.
As a result - double click on MLV and you will see somewhat correct preview, works relatively fast, good enough for clicking through folders with MLVs.

But I suck at LUT making so if Danne have old LUT or someone can make new it will be perfect.

« on: August 28, 2022, 10:05:13 AM »

Look at fast CF card prices before choosing the camera

You probably can do it with 5D2, but you will need some registers manipulations.
There is a build for true 5,6k resolution here on the first page: https://www.magiclantern.fm/forum/index.php?topic=19336.0
Experimental build:5632x3124 @ 3.8fps

And it is 3,8 fps so you need to slow it down to 2 fps (.5s) and adjust shutter speed, should be possible. But I don't know how to do it, what registers to change.
I tried this build (with ~4k resolution because of the slow cf card) and it works, but you need a lot of card space for uncompressed RAW with this resolution.

Thanks! I thought if you tick "creative adjustments" it will break log curve, but..
If I just set "dark strength" to zero - it will look exactly the same as without "creative adjustments" enabled! But now I can do other corrections... cool. Is it mentioned somewhere? How could I not know about it?

General Help Q&A / Re: Cost efficiency of the EOS M + ML setup

« on: August 26, 2022, 11:35:08 AM »

But don't get me wrong, shooting ML RAW is awesome. It is just not as user friendly. Personally I do love it and enjoy working with it.
And if you know your camera and settings that work, then it can be reliable enough..


Main limiting factors for more or less serious work could be:

Card full, because sometimes you can forget how much free space left.. free card space indicator only show you the real number after you reboot the camera. So if there is no space left, recording will just stop, but file saved.

Sometimes recording can stop for various reasons, but it is rare unless you are trying to push it to the max resolution/write speed, etc.

Playback of recorded raw files in camera is very slow and low resolution.

Experimental builds can sometimes crash, rarely but it can happen, and sometimes you will need to format the card. If you have only one card with you, and no laptop - it will be completely useless. I don't know what camera/build/card combination can cause this behavior, maybe it is something very specific and you will never encounter this problem.

And obviously RAW footage takes a lot of GB so you probably need at least a couple of cards and maybe a laptop where you can copy everything.

HDMI preview doesn't work in all modes, so it is hard to share the screen with others. But it is a work in progress, maybe HDMI support will become better in the future.

And overall not so simple process, not really critical, but if you need to keep in mind 1000 things at the same time (lighting, framing, focusing, movement, and always check if everything is OK in the frame and on set) it is not so easy
