Question from a novice

No, this indicated an issue with ffmpeg. What happens if you just call
ffmpeg -i <your_video> frame_%04d.ppm?

[bododge]

I appreciate the reply, you were right ffmpeg wasn't completing the extraction because I was pointing it at the already extracted first frame(s) instead of the .mp4 file...Now all of the .ppm files extract. However I am not having any luck getting the optical flow working. I wish there was some hearty examples of how to set that up to give us noobs a chance of making this thing work! Awesome work though, just wish I could get it going.

Here is the error I get when running the script now. Any ideas what to try next? Why is it returning the project directory instead of the first two frames?

./makeOptFlow.sh: line 44: /Users/sampsen/Documents/Deepstyler/Neural_Video_master/artistic-videos-master: is a directory
./makeOptFlow.sh: line 47: /Users/sampsen/Documents/Deepstyler/Neural_Video_master/artistic-videos-master: is a directory

You are right, we could have provided an example script. I have already included one in my last commit. The lines from your error message refer exactly to the positions where the optical flow utility is called. Could you maybe just update your local copy of this repository, and then use the updated scripts, as explained in the description?

And by the way, you can actually use individual images files as input for this script if you wish. Just replace the frame index by %d, %02d, ... according to the number format.

I downloaded and tried, but I can't run the static binary versions since I'm on a mac. I know that's not really your problem, however I'm trying and trying to get these deepflow and deepmatching to compile and I run into a slew of errors. Any idea what's causing them? If not, I'll keep working on it on my own. Thanks

No, I can't help you with that.
