Advanced photography workflow tips.
As always a work in progress.....Think of this as my personal work in progress whiteboard.
Ultimate convert images to a movie.
ffmpeg -r 30 -f image2 -start_number 2786 -i IMG_%04d.JPG -vf
hflip,vflip,scale=1920:-1 -codec:v prores -profile:v 3 bannanasky_deflickered.mov
https://trac.ffmpeg.org/wiki/Scaling%20%28resizing%29%20with%20ffmpeg
recursively resize. (careful)
find . -name '*.jpg' -o -name '*.JPG' -print0 | xargs -0 mogrify -resize 1024">" -quality 40
find . -name "*.JPG~" -type f -delete
Move odd numbered images to a directory called odd.
mkdir odd; mv *[13579].JPG odd
likewise copy
mkdir odd; cp *[13579].JPG odd
then to quickly make another sequence out of those files...
Making image files into an ordered number sequence.
ffmpeg -r 30 -f image2 -i %04d.JPG -vf
hflip,vflip,scale=1920:-1 -codec:v prores -profile:v 3 preview.mov
Ufraw:
for file in *.UFR ; do mv $file `echo $file | sed 's/\(.*\.\)UFR/\1ufraw/'` ; done
ufraw-batch *.ufraw --out-type=jpeg

ffmpeg -i input.mov -vcodec prores -profile:v NUMBER -an output.mov
For different flavors of ProRes replace NUMBER with a number from zero to 3 where:
0 : ProRes422 (Proxy)
1 : ProRes422 (LT)
2 : ProRes422 (Normal)
3 : ProRes422 (HQ)
ffmpeg -f image2 -r 30 -i a_%04d.jpg -codec:v prores -profile:v 3 movie.mov
#max size that works so far 5008x3339 pixels. not sure if the limitation is on the width or height.

isight or any other camera high quality capture
(it will do up to 100fps)
ffmpeg -f qtkit -video_device_index 0 -i "" -r 30 -codec:v prores -profile:v 1 out2.mov
ffmpeg -f qtkit -list_devices true -i ""

registax --- works on star videos!
turn in camera sharpening off !!.
ffmpeg -i MVI_9673.MOV -vcodec rawvideo -acodec none MVI_9673.avi
for i in *.MOV
do
ffmpeg -i $i \
-acodec none \
-vcodec rawvideo \
$(echo $i | sed 's/\.MOV$//').avi
done
---------------------
imagemagick
also need to install ufraw
convert *.CR2 -average average.jpg
try tif output (many, bits)
convert *.CR2 -average average.jpg
-complex operator
perform complex mathematics on an image sequence
Choose from these operators:
add conjugate divide magnuitude-phase multiply real-imaginary subtract
