Hello, how are you, I get this error, I don't know how to solve it, what am I doing wrong?

Create output video

%cd {FRAME_OUTPUT_DIR} %shell ffmpeg -y -r {60} -f image2 -pattern_type glob -i '*.png' '/content/gdrive/My Drive/{OUTPUT_FILE_PATH}'

Hi! I've seen this happening when it cannot find the frame files (png files) to generate the final video.

You can try interpolation again, making sure you're using the latest notebook (at this location), or:

Thank you very much for your answer, I was able to understand the problem. I solved it by moving the "outup_frames" folder to /content/drive/MyDrive/output_frames. I then ran the command:

%cd /content/drive/MyDrive/output_frames

next:

%shell ffmpeg -y -r {TARGET_FPS} -f image2 -pattern_type glob -i '*.png' '/content/drive/MyDrive/output_frames/output.mp4'

and I was able to get the video.
