I'm trying to make the zoom video using image but facing

TypeError: must be real number, not NoneType.

It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.

i have update the code using traceback,you can see and also details of errors — faisal2k, Aug 12 '23 at 14:59
Some libraries return None when they can't load a file. Given the size of code, and the deep traceback, you probably have the best chance of tracing the problem None back to its source. — hpaulj, Aug 12 '23 at 20:18
Note that it is specifically complaining about `fps`, which is certainly provided as a parameter. I don't see the issue here yet. — Tim Roberts, Aug 13 '23 at 02:03
fps is not issue, the issue is with version of numpy and related lib, i cannot pin point the error — faisal2k, Aug 13 '23 at 04:31
Why do u have duplicated slide = mp.ImageClip(img).set_fps(29).set_duration(audio.duration).resize(size) slide = zoom_in_effect(slide, 0.02) slide.write_videofile('/home/faisal/pythonfiles/videos/zoom-short.mp4',codec='libx264', fps=29)? You should remove this. — toyota Supra, Aug 14 '23 at 00:59
