• Making a timelapse by drag and drop - A rebuild of an old script using ImageMagick

  14 août 2019, par cursor_major

  I have written an apple script previously to automate a task I do in my work many times.

  I shoot Raw + JPG in camera, copy to hard drive.

  I then drag named and dated folder eg. "2019_08_14_CAM_A_CARD_01" on to an automator app and it divides the files in to folders "NEF" and "JPG" respectively.

  I then drag the appropriate "JPG" folder onto my Timelapse app and it runs the image sequence process in QT7 and then saves the file with the parent folder name in the grandparent folder. This keeps things super organised for when I want to re link to the original RAW files.

  [code below]

  It is a 2 step process and works well for my needs, however, Apple are going to be resigning Quicktime 7 Pro so my app has a foreseeable end of life.

  I want to take this opportunity to refine and improve the process using terminal and ImageMagick.

  I have managed to work some code that runs well in terminal, but I have to navigate to the folder first then run a script. It doesn’t do the file renaming and doesn’t save in the right place.

  Also, when I try and run the simple script in an automator ’App’ it throws up errors even before trying to add anything clever with the file naming.

  Later, once I have recreated my timelapse. maker app I want to get clever with more of ImageMagicks commands and overlay a small super of the original frame name in the corner so I can expedite my reconnecting workflow.

  I’m sorry, I’m a photographer not a coder but I’ve been bashing my head trying to work this out and I’ve hit a brick wall.

• Recording a video by webcam on Raspberry Pi [on hold]

  9 août 2019, par Stan Eskin

  Need a python3 script for recording a video by a USB webcam on Raspberry Pi. For instance, I’d like to capture a video to the RasPi’s SD card when a motion sensor gives the signal.

  I’ve found this code for the terminal :
  ffmpeg -f v4l2 -r 25 -s 640x480 -i /dev/video0 out.avi

  Unfortunately, I don’t know how to implement it in my python3 script.
