LCD Powersave while DNG silent pics + Intervalometer ?
« on: February 26, 2016, 02:21:15 PM »
Hello,

Is there a way to turn off the display while taking silent DNG photos in intervalometer mode ?
I'm using a 60D.

I found this topic but it's pretty old so I thought I'd ask again, maybe there's a way now ?

thanks :)

With full-res, simply disable image review in Canon menu (or set it to 2 seconds).

With LiveView, it should work if you enable Powersave in LiveView (but last time I checked it was probably 2 years ago, so if it doesn't work, it's best to report an issue).

thanks for your fast answer :)

intervalometer + "full res" doesn't work at all for me :(

and intervalometer + "simple" works, but the screen is kept alive somehow, doesn't go to powersave mode.

Change "RAW+S1" to "RAW" and retry.

edit: found the issue - https://bitbucket.org/hudson/magic-lantern/issues/2265/turn-off-lcd-enabled-stops-intervalometer

I also found another weirdness (which I don't remember seeing before): right before taking the next picture, it goes to LiveView for a split-second. Looking into it.

edit2: I hope it's fixed now.

In the second case, the LiveView wakes up to be able to take pictures (so that's how it works).

You have to wait for tonight's build. Or compile ML on your own. If you haven't a development machine up and running now ETA might be just the same.

I can confirm the last version works fine ! (interval + HighRes silent pictures)
thank you so much :)

still doesn't go to LCD powersave mode though, but maybe there's no way to achieve that ?

Here it works with display off all the time (full-res + intervalometer, image review off in Canon menu).

Another powersaving tip: the MLV format is much less CPU-intensive than DNG.

The only way to stop using this config (full-res + intervalometer + image review off) is to turn off power (or remove battery or open card door). Correct?
Changing mode using dial will freeze cam.

I usually either change the mode to Av and back, or open the card door. No crashes yet.

Will try on more cameras.

You are right! I got confused because all the buttons seemed to be dead after dial. But half-shutter is bringing LV back.

With LiveView, it should work if you enable Powersave in LiveView

but it works perfectly fine with full res, it's just the "simple" silent pictures that keep the screen on, no matter what.

Yes it's activated.
As I said, just changing from "simple" to "full res" fixes it.

taking screenshots doesn't work here so ... :D



(don't pay attention to the other settings like intervalometer and MLV full res above it)

Just tried with the Feb29 nightly for 60D:



The screen turns off as soon as leaving ML menu, and only wakes up when it takes pictures.

Note my settings are different than those in your screenshot because:
the screen doesn't go black with simple silent picture + intervalometer + image review off in Canon menu

I did not touch image review in Canon menu, as it has no effect in LiveView.

Screenshot also works; what problem did you have with it?

thanks for your reply :) here's 2 videos to illustrate

for the simple MLV + intervalometer : as soon as I change for "Full Res", the screens goes and stays black :)

and one for the screenshot : (i have nothing on the SD card after that)

cheers !

About screenshot: Insert card into cardreader and check for VRAM0.PPM.

Looks like it works exactly the way I've described it.

@Walter Schulz: Thanks ! I had no idea those were actually the screenshots :)

@a1ex : indeed, so in "simple" mode, the LCD wakes up after every picture, but in "full res" mode, the screens stays black. I guess I can live with that ;) to bad for the battery life.

Since I got you here, do you know if it's possible to have a resolution between simple and Full res for the silent pictures ? like 2.7k ? or is it not technically possible ?
thanks

Yeah, it has to wake up in order to take the picture. Could be optimized a little, to turn LV off before saving the picture, but the difference is probably too small to be noticeable.

For intermediate resolutions, you could either use the 5x zoom (it usually is a little larger than 1080p), or crop the full-res image (not worth the coding effort, imo).

What is worth researching, in my opinion, is this: http://www.magiclantern.fm/forum/index.php?topic=10111.msg123909#msg123909

I still don't get why it's stays off in "full res" and doesn't in "simple" :D
But I don't know anything about programming and dev, so i'll shut up now  ;D

thanks for the tip for intermediate resolutions, i'll have a look asap !

Because the simple silent pictures are snapshots from LiveView, while the full-res ones are taken with LiveView turned off, by calling Canon code that's normally used in regular pictures.
