I am having difficulties with a code I am trying to run. Essentially I want to Read in a large .mov video file (60000+frames). Then take each frame individually, process it (e.g. crop and identify particles, I can do these steps) and Export a text file with processing data (can do), plus the cropped image.

I am not sure which functions/the setup to use for reading in a video and exporting an image sequence. I have looked at Import with .mov files, and can identify the number of frames in the movie:

videof = Import[path <> file <> ".mov", "FrameCount"]

as well as view a single frame

frame1 = Import[path <> file <> ".mov", {"Frames", {n}}]

however there is something wrong in the second line of code; no matter the value of n I always get the first image.

Advice is much appreciated.

  • $\begingroup$ Import[Directory[]<>"eclipse1.mov", {"Frames", 420}] works here, and as I change the number (420 in this case) I get different images. If you're having trouble, try it with a small movie first and make sure you have the syntax correct. $\endgroup$ – bill s Feb 6 '14 at 21:19
