Interval capture never less than 2.3 seconds ? #77

Closed PhilZMZ closed 7 years ago

PhilZMZ commented 7 years ago

NX500 lets you set an interval capture time between 1s and 24h. But I don’t know why, interval time can never be less about 2.3 seconds - athough I set it to 1 s - even with superfast memory cards and very small photos (2Mpix) in the lighest mode (normal). You get about the same time with 28MPix raw files (about 40MB). So it is not a buffer issue... It would be very important to me if you could fix this issue, because I need a rate faster than 2.3s and I must use an external remote, which is not very convenient because the camera is used on a drone. Hope you can make something, would be glad to help you if I could, but I have no idea how I can do this…

Best regards from France, Phil

How much faster are we talking about?

PhilZMZ commented 7 years ago

Thanks for the message, ottokiksmaler ;-) As faster as possible. Exposure time is over 1/800s. I tried with an external timer, 1s is too short to record the file, 2s enough, but I can't try between 1 and 2 seconds. I think between 1.5 and 2 seconds would be perfect. If I could know where to change a parameter, it would be great, I could try several values, like 1.6, 1.7, 1.8s...

Is your camera hacked?

PhilZMZ commented 7 years ago

Not yet, but I can do it !

ottokiksmaler commented 7 years ago

I did some tests, fastest I can get is around 1s, but it fluctuates a lot, at 1.2s it's quite stable with a fast card (or smaller file sizes).

PhilZMZ commented 7 years ago

Great !!! How can I test, Otto ?

ottokiksmaler commented 7 years ago

Do you know you way around linux/bash/etc?

If yes: https://github.com/ottokiksmaler/nx500_nx1_modding/blob/master/Testing%20programs%20-%20HOWTO.md

ottokiksmaler commented 7 years ago

So, hack the camera, copy this file to SD card root directory as stapp (https://github.com/ottokiksmaler/nx500_nx1_modding/blob/dev/stapp?raw=true), put SD in camera, power on the camera, start telnet, telnet to camera and do:

/mnt/mmc/stapp "app nx capture single"

It should take a photo (you can also turn on silent shutter in order to preserve the shutter). If it works, try this:

/mnt/mmc/stapp "app nx capture single"; sleep 1.2;/mnt/mmc/stapp "app nx capture single"; sleep 1.2;/mnt/mmc/stapp "app nx capture single"; sleep 1.2;/mnt/mmc/stapp "app nx capture single"; sleep 1.2;/mnt/mmc/stapp "app nx capture single"; sleep 1.2;

or 

for i in `seq 1 10`; do /mnt/mmc/stapp "app nx capture single"; sleep 1.2; done

This should take a sequence of images and allow you to relatively finely tune the delay between photos. For test you could take a sequence of photos of a stopwatch on you cellphone or similar.

PhilZMZ commented 7 years ago

Thanks a lot, I try this afternoon and tell you.

Do I need to be under linux environment to make this ?

My knownledge of Linux is very poor, but I will try. If I don't succeed, I call a neighbour who is much better than me :-)

Thanks for sharing your knowledge, Otto !

ottokiksmaler commented 7 years ago

No Linux needed on your PC, Linux is on the camera :)

PhilZMZ commented 7 years ago

Sorry Otto, I am afraid I need a little bit more help.... I have hacked the NX500 with last version I turn on wifi, connect to the box, launch Telnet I start Putty, enter 192.168.1.13 port 22 (default) Check "telnet" click open. After a few seconds I get the message

Then I type "/mnt/mmc/stapp "app nx capture single" I have to wait for about 20-30 seconds before I can see this text (when it is displayed...) And nothing happens, no photo is taken...

Maybe I am wrong somewhere... but where ? Any idea ?

ottokiksmaler commented 7 years ago

That's weird, you should have no issues whatsoever with accessing the camera via telnet. Could you type dmesg On the command line and post the last twenty-ish lines here? And exact network error you get.

ottokiksmaler commented 7 years ago

Also try from command line st app nx capture single

PhilZMZ commented 7 years ago

Hi Otto, Sorry for the late answer too busy these days...

I have tried with several NX500, always the same problem : the communication between the PC and the camera via wifi / Telnet always crashes, I don't know why. I never could take a picture with the command line. As you requested, you will find at the bottom of this messages all the lines after typing dmesg.

I think 1.5 s should work well, I don't know if you could add this to the hack ? Or add several values in the intervall settings under 2s, as 1.2s, 1.3s, 1.4s... until 1,9s

The error I get is : Network error : Software caused connection abort putty fatal error

PhilZMZ commented 7 years ago

I found a solution ! At first, I removed NX-KS2 and installed nx-on-wake (https://github.com/ottokiksmaler/nx500_nx1_modding/tree/master/nx-on-wake)+ nx patch 5.3 (https://github.com/ottokiksmaler/nx500_nx1_modding/tree/master/video-bitrate-mods/nx-patch). Then I put on a sd-card several files (including stapp and the following script in a file named "phserie.sh"

_#!/bin/bash while true;

for i in seq 1 10;

do /mnt/mmc/stapp "app nx capture single" sleep 1.2 done_ Thanks to Cedric for the help ! I start the sequence pressing together AEL + Exposure compensation buttons, and it works fine ! I can easily change the number of photos and the interval. Maybe you could include this feature in a next version ?

ottokiksmaler commented 7 years ago

I have made a tool mod_lapse that more or less does what you described, plus some more :)

It would be appreciated if you could test it and report back your findings

PhilZMZ commented 7 years ago

Thanks for this tool, Otto... But can you please explain in a few words how I can use it ? I copy the file on the SD Card ? Other files too ? Which mod version do I use ? 2.49 or 5.3 (Vassile Dumitrescu) ?

ottokiksmaler commented 7 years ago

What do you have currently installed? Vasile's hack?

PhilZMZ commented 7 years ago

Vasile's 5.3 on one camera, 2.49 on another one (I have 6 NX500 :-)

ottokiksmaler commented 7 years ago

Had to find an unused key combination, seems EV+OK is not used for anything in both packs (somebody correct me if I'm wrong). See here https://github.com/ottokiksmaler/nx500_nx1_modding/blob/master/tools/README.md for instructions. Should work with both mod packs.

PhilZMZ commented 7 years ago

Yes, works fine ! A question : why are there 2 mod packs ? It seems 2.49 has more features than 5 ? Right ?

ottokiksmaler commented 7 years ago

Uh, long story, TLDR version is

Vasile - faster starting (almost as soon as the camera is powered on, but needs a more aggressive hack), leaner, mostly made in C/C++

KS - slower to start from cold (after removing the battery or long inactivity, but minimal modifications to camera), tied to Bluetooth switch, based on shell scripts, contains everything and then some.

They have two different philosophies, choice is a good thing :)
