Full-resolution silent pictures (silent.mo)

[a1ex]

In this case, it's probably not the file name, but the image catalog. When taking a picture, Canon code not only saves the image to card, but also adds it to this catalog (some sort of index stored in the RAM). How exactly this catalog works, in particular how to add files to it, is not yet understood.

If you restart the camera, do the files appear on the remote computer?

The renaming trick is known to work on Eye-Fi cards, btw. Some cards other than Eye-Fi may be able to transfer arbitrary files out of the box.

Hi,

an hour ago i had the same idea About the WiFi Card (before i read your post). in Germany we say "zwei dumme, ein gedanke" - "two stupid, one thought"

i will try a toshiba WiFi sd Card. hope this will work.

the silent files do not appear after restart the camera.

thx again!

[a1ex]

That will work. Make sure you get the W-04 version; reviews say it's much faster than W-03.

      @ All Who Refer to Stills Mode as Photo Mode

"Photo mode refers to "normal" stills camera operation" > But Probably Really Shouldn't !

   No idea Whom, When, Why "Photos Mode" started being used to refer to "Stills Mode".

Since Everything our cameras do Visually is Photo Capturing, Our Cam's are in "Photos Mode"

whenever they are "On". Since those Photos can be Captured as Still Photos or Moving Photos,

the 2 Main Photo Capture Modes should be referred to as Stills & Movies.

   Which is actually the way Canon does it in their Manuals .

Small question, I've tried silent pictures after a long time, just to be sure I've got it right. Full res is still limited to 1/10 right? I tested it and it looks like it.

Hi,
Is FRSP should give the same color and exposure results as in a regular Photo mode with cr2?
I tried the same setting and opened pics in ACR (sorry for poor quality).

With 0,3", f16, iso 320 - FRSP captures picture twice longer (about 600 ms) = 0,6".

My camera is 5d3 with expo override enabled. Should I change some settings to match closer?





Thanks

Hi mash.m

Where you able to transfer file from your camera to the PC using FRSP? I stumbled upon the same scenario, trying to use a EOS 50D to digitize Super 8 and a 400 Ft reel is about 28800 images so using the shutter will kill the camera.
I hex edited the silent.mo and changed dng to CR2 extention and all files are saved as CR2 file but nothing shows up. In ML they are visible but not in EOS menu/software on the camera so same thing happens in gphoto2 so this is as a1lex say most probably the image catalog on the memory that is not updated.

If anyone got the WFT-E3A, I am wondering if the WFT-E3A would work with FRSP, dose the EOS write directly to a usb attached disk or does it write to the memory card first and then copy to the external media. with 28800 images on 400Ft reel a CF card or SD card would be to small we are talking 100's of GB before post processing :-)

regards,
GM

It will be possible allow take photo during recording MLV-lite without affect to recording output?

[a1ex]

Yes, as long as photo resolution is not (much) higher than video resolution.

Changing LiveView resolution on the fly might be possible; I had some half-successful attempts at that; however, capturing a full-res image takes time, so the video stream would be interrupted (you will lose a few frames, depending on how fast the resolution can be switched; rolling shutter time for a full-res image is about 130ms on 5D3).

One way to approximate full-res capture without interrupting the video stream would be to shift the "phase" in the 3x3 pixel binning (the initial row and column of each 3x3 pixel group). That might be doable from ADTG and/or CMOS registers. If you have the patience to adjust these in adtg_gui and notice sub-pixel image movements, or maybe write a script to automate that process, you may find that register (assuming it exists). If you can also find a way disable the column binning, i.e. read out one single pixel out of 3 horizontal ones, on cameras other than 5D3 you would need 9 video frames to "assemble" one full-res image. Of course, that would only work for static scenes.

Without a way to disable the line/column binning, even if you can shift the initial line/column, recovering a full-res image is going to be difficult. Some deconvolution or super-resolution techniques might help, in particular if the scene is not exactly static when you take the picture.

Difficulty: give me 5 years and a team of researchers

I was interested in long exposure fix some time ago, but wasn't able to understand how to work on this module and dig manually into commit's history to make Greg code works on update codebase.

So I remembered about this and managed to update FRSP Bulb code with latest changes in ML repository.

Here is the diff for unified branch (test also in lua-fix, not tested on top of crop_rec_4k)

The approach was, indeed, a bit of a maintenance burden, as different camera models use different offsets (so it's easy to make mistakes). However, it is something that can be validated in recent QEMU (which, back then, wasn't advanced enough).

I'd also prefer to have it on top of the patch manager backend - which works pretty well, with one exception: when I take it outside, it gives ERR70. When I get back inside to track the error, it works fine.

For the above reasons, I did not decline the PR, but preferred to wait. Unfortunately, the PR was declined by the author.

Apart from patching bulb address, how to patch cache? Do refactoring this to use patch manager would require much time?
Maybe I can looks how to use it in the free time.

Submitted PR #941 to main repo to have it as reference (Greg PR was discontinued and code can only be found digging deep into this thread).
I hope that is still interesting to someone

Not had any luck making this module work. Read the Help files – but can't see anything relevant to my problem.

Using Danne's crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Apr02.5D3123.zip  build https://bitbucket.org/Dannephoto/magic-lantern/downloads/

Once module is enabled, half-press shutter has message on liveview screen: Preparing… then I get a Canon black screen with a white BUSY. Sometimes also a Canon spinning laser-disc gif (never seen this ever before) 'Saving' . Camera then locks up and requires battery pull. No image saved to card.

Also, can a 5D3 user please share exactly how to set up the correct Canon Custom Function for the half-press shutter capture?

Many thanks.

Try with regular builds, or with those from the Experiments page.

Default Canon settings should be OK. If using AF, you may want to enable back button focus in Custom Controls, but ML help already tells you to do that. Or, if there are any other settings you need to change - that I'm aware of - ML menu will tell you so.

@a1ex Righto, I see. Thanks! Couldn't find anything about setting the CFN buttons on the HELP wiki. Was I looking in the right place?

[timbytheriver]

Loaded the experiments page Jul22_2018 4K build.

Still not working as expected: 

Pressing the back focus button now produces: 'Preparing' message top left Liveview … then 'Hold On'. Then 'Preparing' stays on the screen.
No lock ups. But no images on any card. File manager > view of any image on card produces black screen with what looks like random white characters.

Still can't get CFN to set trigger correctly!

[a1ex]

The "Hold on" message means it's waiting to see whether the camera is going to autofocus, or not. Keep the button pressed for a little longer, or try MF.

The help is shown in ML menu, at the bottom of the screen (the fine print). What does it say? It's dynamic (i.e. not a fixed text).

[timbytheriver]

Help text: Says 'assign AF to * button' (done)

Still get 'Hold on' during any length of hold of trigger. Now it locks up again with strange messages (see images). Batt pull resets. No image saved. All imaged viewed are scrambled text (see image).

Small steps required, timbytheriver!

JPG? Set image quality to RAW only. Review time 5 seconds. Make sure powersave is > 1 minutes. And set color space to sRGB. Make sure to use cam's M mode. For starters: ISO 200-800, Tv = 1/30, open aperture. Lens AF off. Single picture mode.
Restore ML default settings, reboot. Enable silent.mo, reboot. Enter Shoot tab, enable Silent pics with default settings. Enter LiveView mode and press half-shutter.
If it works (check pic on computer) enable FRSP and retry. Report back.

@Walter Schulz Thanks for the tips. Dashing out now – but will pick this up again tomorrow.

Good day. please help. How to make Flash work with silent.mo?

I also work with photogrammetry. I have to take 2 pictures at each turn (32 turns on table), since I use the flash mode "freemask". I activate the shutter of the camera on the radio synchroniser.in order to save the shutter resource, I need the ability to fire the flash in the "silence shot" mode
