Python module to capture time lapse videos on Raspberry Pi
It's recommended to create a virtual environment:
python -m venv pilapse
cd pilapse
source bin/activateFor video compiling, simply install pilapse from PyPi:
pip install pilapserecFor recording or image capturing, you also need picamera module:
pip install pilapserec picameraTo capture an image only (can be used to check the camera beforehand):
pilapse captureTo record a long video:
pilapse recordTo make a video out of captured images:
pilapse compileHowever, you are advised against video compiling directly on Raspberry Pi, as the system resource may run low and you are almost certainly to be kicked out of the SSH session. For the same reason, you are advised against using the --auto-compile switch. After record session, you can plug the microSD card into your main work station and compile them there.
To manually clean up the working directory (if you specified --preserve while recording):
pilapse cleanFor more options, refer to --help command:
(pilapse) aki@hakune:~/pilapse $ pilapse --help
piLapse - capture time lapse video on Raspberry Pi.
Usage:
pilapse capture [-i <image-name>] [-s <save-dir>] [--no-time] [--verbose]
pilapse record [-d <duration> | -c] [-f <frequency>] [-l <length>] [-w <width>] [-s <save-dir>] [-S <wait-time>] [--auto-compile] [-o <video-name>] [-F <fps>] [--no-time] [--preserve] [--verbose]
pilapse compile [-s <save-dir>] [-o <video-name>] [-F <fps>] [--preserve] [--verbose]
pilapse clean [-s <save-dir>]
pilapse (-h | --help)
pilapse --version
Actions:
capture Take 1 image only.
record Record a timelapse video.
compile Compile labelled images into a video.
Options:
-h --help Show this screen.
-c --continuous Set to continuously run mode.
-d --duration DURATION Set recording duration (by seconds) [default: 600].
-f --frequency FREQUENCY Set time interval between shots (by seconds) [default: 5].
-F --fps FPS Set final video fps [default: 24].
-l --length LENGTH Set image length dimension (by pixel) [default: 3280].
-w --width WIDTH Set image width dimension (by pixel) [default: 2464].
-s --save-dir SAVINGDIR Set working and saving directory [default: ~/Videos/pilapse].
-S --shutter-wait TIME Set timer before start capturing (by seconds) [default: 0].
-i --image-name NAME Set image name in capture mode [default: image.jpg].
-o --output-video NAME Set output video name.
-a --auto-compile Automatically compile images [default: True].
-p --preserve Do not automatically clean up after recording.
-n --no-time Do not add time in capture mode.
--verbose Set to verbose mode.
--version Show version.To keep the process running after log out of SSH, you can use screen or tmux:
sudo apt install tmux
tmux
pilapse recordIf you encounter numpy error while making videos on Raspberry Pi, run this command and try to compile again:
sudo apt install libatlas-base-dev ffmpegLiterally any other issue can be solved with:
pip install --upgrade moviepyAny contribution is deeply appreciated.
