Thanks for the cultural context but it still doesn't make any sense. No one gets any sense of who the character is and why he should receive special treatment. If you are trying to relate something sinister, skip the soft acoustic guitar music next time.

I'm not asking to record from the camera directly onto the computer, I want a command-line solution for recording clips of certain length, then transferring to PC after recording is stopped.

The functionality exists, as it is included in EOS Utility, but I want it to be part of a scripted workflow (record video, do basic processing, add to playback queue. gphoto2 does not do this, it seems. Any suggestions?

So far my non- ML approach is using the remote shutter that triggers a selftimer (10 sec) and then does a continuous 5 frames.  This works very well except that continuous shooting is very fast.  Ideally for a photo booth there would be 1-2 seconds between each shot.

How does your remote shutter shoot 5 continuous frames?

Is that script up somewhere?  could you link to it?

Code: [Select]
 @title Photo Booth Looped

while (TRUE)

for (int i = 0; i < 4; i++)

for (int l = 0; l < 5; l++)
while (TRUE)
if (get_focus_confirm()) break;



Edit: fixed a comment that breaks the script

Be forewarned, there is no way to stop the script without turning off the camera, which might lead to an incomplete shutdown and thus some unforeseen problem.

I was working on a handmade wired remote which in theory is easy to put together as this is for the 550D which uses a 3-pole 2.5mm remote release port but I think I'm abandoning this approach.

At this point I'm not using any ML function for my photo booth. I decided it was faster and more reliable to trigger via the computer tethered to the camera. I'm using bash scripts along with gphoto2 and ImageMagick to wait for a keypress, capture the images, process them into a print template, print, and move the captured images into a folder that is being displayed on a monitor. This is on OSX although it should also work just fine on any *nix system.

I can give you some more details on this if you are interested.

Now I just need a single key USB button that doesn't cost $30.

Thanks for reply, adding extra focus steps will be really useful. The Rack focus end point isn't a bad workaround as we all know a good timelapse is all in the setup...

It's strange how much the focal distance effects the number of steps, I wonder if it's constant from one lens to another, I only have one variable focus lens but I could see if it matches number of steps at 50mm against my nifty 50.. I'll try and post a chart for 24-105mm

Thanks for the advise with LiveView - I'll try and find a way to shut off it off once TL is started either that or will need to purchase a few extra batteries..  ;)

It definitely is not constant from lens to lens. So many variables such as the motor in the lens as well as the range of the focus ring. It's not even consistent within a lens. My 100mm macro feels almost exponential in the proportion to each step (or physical turn of the ring). By this I mean as you go from the closest focal distance to infinity, the sensitivity of the ring substantially increases. This would make sense for a macro lens where you want a lot of control when focusing on objects at a macro range.

I'm trying to figure out a decent solution for this as well. For now I'm using a PicoC script stuck in an infinite loop and a nightly build from April that still had PicoC support. I'm trying to figure out how to implement this in a module but not really sure how to do that.

If you're doing this professionally, you need to get some sort of support/stabilizer and a more consistent look (as in post). Shakey hand-held shots of stuff that would be easily captured as stills doesn't add a lot to the clients memory of the day.

Not sure how you are comparing the color accuracy of a camera you don't have yet, recording in a format it doesn't support.

But yes the 5d2 is still a very good camera.

Put the lens cap on.

There are already so many submenus and options in ML in general that it would get out of control if menu items started showing up twice.

Don't zoom in to 100%.

To answer your question, no there is no drop in image quality for RAW video when you set stills quality to something other than RAW.

The in-menu help is not available on non-stable builds like the nightlies. HDR is under advanced bracketing, bulb ramping has been abandoned and replaced with better options (AutoETTR w/ sidecar files), and the different Picture style option should still be there.

Exactly, there is no active computation or anything that would be able to detect changes in the scene.

Read the FAQ and then turn off the Canon overlays by cycling through the screen modes with the INFO button while in liveview.

I'm curious as to why you would want a cr2hdr conversion tool on your tablet. The resulting DNG files still need a good deal of PP to get them to look decently exposed. Then you're going to need Lightroom or GIMP/dcraw or whatever running on your tablet also. You might as well just wait until you are back at your 'editing' computer.

Seems like a waste of time. If you are just wanting a preview, then image review does a pretty decent job of blending the exposures.

8086 ;)

It was around 2mhz iirc.  The turbo button on my old box got it to 8mhz  ;D

I remember playing an old military action game and hitting the turbo to get to the good parts :) Now my phone has a dual-core 1.something ghz processor.

General Help Q&A / Re: ML 2.3 SDXC 64GB won't boot! (no0b)
« on: September 05, 2013, 02:16:18 AM »
Yes you have to run the firmware upgrade once to enable the bootflag on the camera. This tells the camera to search for bootable code on startup.

MLV is the future standard format for ML raw video. It is still under development but hopes to include audio support, amongst other things.

Check out the first post in this thread for more details.

They run a different OS with different hardware. It's all reverse engineered so it is done from scratch.

tried to convert some video dngs (son of a batch) in vmware windows 7 with the latest cr2hrd but got an error..
so what can i do now?

black subtrackt didn´t work
bright dark detection didnt work
iso blending didnt work..

greets. sw

Sounds like you are lacking dcraw.

have you tried a card with canon firmware? maybe you may need to reinstall canon firmware?

'Reinstalling' Canon firmware never helps, as it was never replaced to begin with. I've never run into this issue with any camera that I've put ML on. Is there any responsiveness from the camera from any button press?

Archived scripts / Re: Nightly Build w/ Script Functionality

The additional of modules prompted the dropping of PicoC and the addition of TCC, another scripting language. The scripting API has not been reimplemented for TCC but is on Alex's agenda.

Yea, I had to make that file also. FYI, the command 'touch whatfileyouneed.h' will create a file of that name with no content, rather than saving an empty text doc or something like that. What is your error now?

I used MacPorts to install truncate. You might have to also remove the -s flag after the truncate command in makefile.src
