What is the image capture time used by Pix4D with the matching strategy “use image capture time” ?
Is it a flag in the image exif, or the file creation time, or does Pix4D consider the images in their alphabetic order?
I am asking this question because I extract frames from a video using ffmpeg, and I am not sure how ffmpeg handles this and if the proper image sequence is still known to Pix4D.
My final goal is to start a project with few video frames (let’s say, 1 or 2 fps) and recursively add new frames around the frames that could not be calibrated. In this case the file creation time would not retain the right sequence because new frames would be inserted at a later iteration. Is this going to be an issue?
Thanks a lot for your help!
