issue regarding stylizing video frames

[kmeagle1515]

I am trying to stylizing video frames which are in video_input folder and used advanced bash command on your github for the same but i don't know how to generate flow files using make-opt-flow.sh
can you tell me the steps?

i guess make-opt-flow.sh file is run using :
./make-opt-flow.sh "world_video_frames1/frame_{}.ppm" "video_output"
my frames are in format frame_0001.ppm

just ran into the same issue, were you able to figure this out?

It is working for me, you have to add the %04d so the parser recognize your frames:

bash make-opt-flow.sh my_folder/my_frames/frame_%04d.ppm my_folder/my_opticalflow_folder

If you want to manually extract the frames, you can run this:

ffmpeg -i video.mp4 my_folder/my_frames/frame_%04d.ppm
