I have a set of 934 images extracted from a 30-second video at 29 FPS.
I tried the Photoshop method, but it is time consuming and too slow, so i went with method two and three,
I'm not very comfortable with programming, but I know how to use the terminal a little bit.

Normally the commands looks like that:

Code: [Select]

cd C:\Users\strig\Videos\Sequence 
align_image_stack -a *.jpg
# or
align_image_stack -a 1001.jpg 1002.jpg 1003.jpg ....
With my terminal command, I get this:



So i am a bit confused, hope you can clarify me.

if aknyone could send me to a more convenient way to use the align feature https://wiki.panotools.org/Align_image_stack

i hit

C:\Users\strig\Pictures\102CANON\LRTimelapse\LRT_MVI_0887>"align_image_stack.exe" -a *.jpg

in the terminal but without fine control, i saw align_image_stack.exe running in the task manager, wait more than 30mn (i'm on a 12th Gen Intel(R) Core(TM) i7-12700H  2.70 GHz with64Gb ram and intel irisx and nvidia GF rtx3060 laptop) and had to stop the process a hour after.
