Python path not found

Hello everyone, I received a Python code that I had asked a friend for. It allows for slight modifications to a video in an INPUT folder and outputs the changed version in an OUTPUT folder. It works on his PC, but I'm having a problem with the file paths on my PC.
Here is the Python code =>
import cv2 import numpy as np import random from moviepy.editor import VideoFileClip def get_exposure_preset_parameters(preset): exposure_presets = { "Subtle": (0.9, 1.1), "Light": (0.8, 1.2), "Moderate": (0.7, 1.3), "Strong": (0.5, 1.5), } return exposure_presets.get(preset, (0.8, 1.2)) def get_brightness_preset_parameters(preset): brightness_presets = { "Subtle": (-5, 5), "Light": (-10, 10), "Moderate": (-15, 15), "Strong": (-30, 30), } return brightness_presets.get(preset, (-10, 10)) def get_contrast_preset_parameters(preset): contrast_presets = { "Subtle": (0.9, 1.1), "Light": (0.8, 1.2), "Moderate": (0.7, 1.3), "Strong": (0.5, 1.5), } return contrast_presets.get(preset, (0.8, 1.2)) def get_saturation_preset_parameters(preset): saturation_presets = { "Subtle": (0.8, 1.2), "Light": (0.7, 1.3), "Moderate": (0.5, 1.5), "Strong": (0.4, 1.6), } return saturation_presets.get(preset, (0.7, 1.3)) def print_video_parameters( video_index, exposure_factor, brightness_factor, contrast_factor, saturation_factor, mirror_effect, noise_level, rotation_angle ): print( f"Video {video_index + 1} generated successfully, " "metadata removed, anti-shadow protection activated." ) print(f"Parameters used:") print(f"Exposure: {exposure_factor}") print(f"Brightness: {brightness_factor}") print(f"Contrast: {contrast_factor}") print(f"Saturation: {saturation_factor}") print(f"Mirror effect: {'Activated' if mirror_effect else 'Deactivated'}") print(f"Noise level: {noise_level}") print(f"Rotation angle: {rotation_angle}\n") def add_noise(frame, level): h, w, c = frame.shape noise = np.random.normal(0, level, (h, w, c)) noisy_frame = np.clip(frame + noise, 0, 255) return noisy_frame.astype(np.uint8) def rotate_video(frame, angle): h, w, _ = frame.shape center = (w // 2, h // 2) rotation_matrix = cv2.getRotationMatrix2D(center, angle, 1.0) rotated_frame = cv2.warpAffine(frame, rotation_matrix, (w, h)) return rotated_frame def adjust_video_parameters_with_presets( input_video_path, output_video_path, exposure_preset, brightness_preset, contrast_preset, saturation_preset, mirror_effect=False, noise_level=None, rotation_angle=0 ): exposure_range = get_exposure_preset_parameters(exposure_preset) brightness_range = get_brightness_preset_parameters(brightness_preset) contrast_range = get_contrast_preset_parameters(contrast_preset) saturation_range = get_saturation_preset_parameters(saturation_preset) NUMBER_OF_VIDEOS = 5 cap = cv2.VideoCapture(input_video_path) width = int(cap.get(3)) height = int(cap.get(4)) fps = cap.get(5) fourcc = cv2.VideoWriter_fourcc(*'XVID') print(f"Input video path: {input_video_path}") print(f"Output path: {output_video_path}") print(f"Video width: {width}") print(f"Video height: {height}") print(f"Video FPS: {fps}") print(f"Mirror effect: {'Activated' if mirror_effect else 'Deactivated'}") print(f"Noise level: {noise_level}\n") for i in range(NUMBER_OF_VIDEOS): exposure_factor = random.uniform(*exposure_range) brightness_factor = random.uniform(*brightness_range) contrast_factor = random.uniform(*contrast_range) saturation_factor = random.uniform(*saturation_range) out = cv2.VideoWriter( f"{output_video_path}_{i}.mp4", fourcc, fps, (width, height) ) while True: ret, frame = cap.read() if not ret: break frame = cv2.convertScaleAbs( frame, alpha=contrast_factor, beta=brightness_factor ) hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV) hsv[:, :, 1] = hsv[:, :, 1] * saturation_factor frame = cv2.cvtColor(hsv, cv2.COLOR_HSV2BGR) if mirror_effect: frame = cv2.flip(frame, 1) if noise_level is not None: frame = add_noise(frame, noise_level) frame = rotate_video(frame, rotation_angle) out.write(frame) out.release() print_video_parameters( i, exposure_factor, brightness_factor, contrast_factor, saturation_factor, mirror_effect, noise_level, rotation_angle ) cap.set(cv2.CAP_PROP_POS_FRAMES, 0) cap.release() cv2.destroyAllWindows() def remove_metadata(input_video_path, output_video_path): video_clip = VideoFileClip(input_video_path) video_clip.write_videofile( output_video_path, codec="libx264", audio_codec="aac", remove_temp=True, logger=None ) # Example usage with mirror effects, # noise and rotation manually chosen input_video_path = 'c:/Users/Eleve/Desktop/BOT_Tiktok/Tiktok_INPUT/Entry_file.mp4' output_video_path = 'c:/Users/Eleve/Desktop/BOT_Tiktok/Tiktok_OUTPUT/Output_file.mp4' exposure_preset = "Subtle" brightness_preset = "Light" contrast_preset = "Moderate" saturation_preset = "Light" rotation_angle = 0 # Rotation angle in degrees adjust_video_parameters_with_presets( input_video_path, output_video_path, exposure_preset, brightness_preset, contrast_preset, saturation_preset, mirror_effect=False, noise_level=None, rotation_angle=rotation_angle ) Thanks in advance

Given the description and without further clarification, I suspect that
input_video_path and/or output_video_path do not point to an existing file/folder.
I mainly work in VB6, VB.NET, and C#, but moderation often leads me to other languages.
In VB.NET, remember to enable "Option Explicit" and "Option Strict".
Hello,
You didn't specify the exact error message.
Can you test this?
import os def pf(path): r=os.path.exists(path) if r : print(path + " exists.") else: print (path + " does not exist.") chem1='c:/Users/Eleve/Desktop/BOT_Tiktok/Tiktok_INPUT/Fichier_entree.mp4' pf(chem1) chem1='c:/Users/Eleve/Desktop/BOT_Tiktok/Tiktok_OUTPUT' pf(chem1)
Hello,
Show us the error message.
Do you have a Windows user called Eleve on your PC? And are you logged in with this user to run the program?
In command line mode, run the following command:
dir c:\Users\Eleve\Desktop\BOT_Tiktok\Tiktok_INPUT\ Note that, according to the prompt displayed in your image
you are already in C:\users\Student
you can still type
cd Desktop\BOT_Tiktok\Tiktok_INPUT
and when the prompt looks like this:
C:\users\Student\Desktop\BOT_Tiktok\Tiktok_INPUT >
you will type
dir
In your image from 31/12 at 5:48 PM, we saw the following prompt:
C:\users\Elève>
showing that you are in the Elève folder
So I suggested on January 1 at 11:57 AM that you navigate to the folder
Desktop\BOT_Tiktok\Tiktok_INPUT
by doing
cd Desktop\BOT_Tiktok\Tiktok_INPUT
However, in this message, we see in your image the prompt
C:\users\Elève\Desktop\BOT_Tiktok\Tiktok_INPUT>
showing that you are already in Tiktok_INPUT !!!!
So obviously, if you do, from this folder:
cd Desktop\BOT_Tiktok\Tiktok_INPUT
it doesn't work!
There is no folder
C:\users\Elève\Desktop\BOT_Tiktok\Tiktok_INPUT\Desktop\BOT_Tiktok\Tiktok_INPUT
What is certain is that if the folder is really called "Elève"
with a grave accent on the "e", you need to write:
input_video_path = 'C:\Users\Elève\Desktop\BOT_Tiktok\Tiktok_INPUT\Fichier_entree.mp4'
Same with output_video_path ....
Alright, it's changed, that's good.
Look when I search for the location of my video in my files:

And also I tested typing this in the terminal:
C:/Users/Student/Desktop/BOT_Tiktok/Tiktok_INPUT/Fichier_entree.mp4
and it opened the video.
So that was for the input video and now when I type:
C:/Users/Student/Desktop/BOT_Tiktok/Tiktok_INPUT/Fichier_sortie.mp4
for the output video, it tells me this. (noting that the video "Fichier_entree.mp4" does not exist unlike the input "Fichier_entree.mp4"):

Yes, that's exactly the problem. I have indeed put the file in the right place and set the correct path to the file. But it's stuck... I really don't know what to do anymore.
I am on a Windows 11 PC, and I am not sure if it is related to the path notation.
