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

  14 August 2019, by 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.

• ffmpeg command running stand alone but not from a linux script

  31 May 2016, by user1490563

  i made a simple script that breaks a flv file into multiple parts, convert them all to .mp4 individually and then merge all of them to form a final mp4 file. i did this to save time and convert large files in parallel.

  however, i am stuck because the command that normally run on command line for ffmpeg, dont run via script.

  I am kind of stuck here and will like to have some assistance.

  #!/bin/bash
  
  
  
  
  
  #sleep 5
  
  
  
  
  
  filenametmp=$1;
  
  
  
  filename=`echo "$filenametmp" | awk '{split($0,a,"."); print a[1]}'`
  
  
  
  
  
  echo $filename
  
  
  
  output="$filename-output"
  
  
  
  filenamewithoutpath=`echo "$output" | awk '{split($0,a,"/"); print a[4]}'`
  
  
  
  echo $output $filenamewithoutpath
  
  
  
  /usr/bin/ffmpeg -i $filenametmp -c copy -map 0 -segment_time $2 -f segment $output%01d.flv
  
  
  
  #sleep 10
  
  
  
  
  
  #echo "/bin/ls -lrt /root/storage/ | /bin/grep $filenamewithoutpath | /usr/bin/wc -l"
  
  filecounttmp=`/bin/ls -lrt /opt/storage/ | /bin/grep $filenamewithoutpath | /usr/bin/wc -l`
  
  
  
  filecount=`expr $filecounttmp - 1`
  
  
  
  echo $filecount
  
  
  
  for i in `seq 0 $filecount`
  
  do
  
  
  
  
  
  suffix=`expr 0000 + $i`
  
  
  
  filenametoconvert="$output$suffix.flv"
  
  convertedfilename="$output$suffix.mp4"
  
  echo $filenametoconvert
  
  
  
  /usr/bin/ffmpeg -i $filenametoconvert -c:v libx264 -crf 23 -preset medium -vsync 1 -r 25 -c:a aac -strict -2 -b:a 64k -ar 44100 -ac 1 $convertedfilename > /dev/null 2>&1 &
  
  
  
  
  
  done
  
  
  
  
  
  
  
  
  
  
  
  sleep 5
  
  
  
  concatstring=""
  
  
  
  for j in `seq 0 $filecount`
  
  do
  
  
  
  
  
  suffix=`expr 0000 + $j`
  
  
  
  convertedfilenamemp4="$output$suffix.mp4"
  
  
  
  #concatstring=`concat:$concatstring|$convertedfilenamemp4`
  
  
  
  echo "file" $convertedfilenamemp4 >> $filename.txt
  
  
  
  #ffmpeg -i concat:"$concatstring" -codec copy $filename.mp4
  
  
  
  #ffmpeg -f concat -i $filename.txt -c copy $filename.mp4
  
  
  
  
  
  done
  
  
  
  echo $concatstring
  
  
  
  ffmpeg -f concat -i $filename.txt -c copy $filename.mp4
  
  
  
  
  
  rm $output*
  
  rm $filename.txt

  following is how to run this on any flv file

  ./ff.sh /opt/storage/tttttssssssssss_573f5b1cd473202daf2bf694.flv 20

  Any help will be appreciated and any input required will be given.

  I am on Ubuntu 14.04 LTS version. Standard installation of ffmpeg.
