After sending my first post I realized the source movie was an .avi and not a .mp4. I did then try to convert the .avi to a .mp4 and then do the actions described below. I was able to open and extract frames. The movie in question, however, is from a 180 fps Gig-E camera. The camera controller outputs a .avi file and the resulting file is several GB in size. When I convert to .mp4 its size shrinks to ~ 0.5 MB and its no longer 180 fps. I also suspect I'm losing resolution in the compression process. I didn't look into the conversion application to see how to preserve the original frame rate, but exporting using Image J seems to preserve everything.

I appreciate all the discussion from the community. It has been very helpful.

Cheers,

Dan

You should be able to extract frames using PlayMovieAction on mp4 movies. Review the docs and especially the open keyword (if memory serves, I am on an iPad currently.)

Subject: Extracting frames from movies in Igor

Hello Everyone,

I knew this day was coming, but was hoping there would be a solution before it happened. I have for a long time used Igor?s PlayMovie and PlayMovieAction commands to load, play and extract frames from QuickTime movies in .mov or .mp4 formats. I haven?t used it for a little bit, but now when I try, I get an error message saying this feature is no longer supported by my OS.

The question is, is there currently any way to open, play and extract frames from .mp4, .mov or .avi movie files in Igor ??? Some simple searches haven?t yielded anything.

Igor Pro 8.04
Mac OS X 10.14.6

Thanks in advance,

Dan
