Animation rendering issue (Blender).

Solved

Hello,
I am a beginner in Blender but I still managed to make an animation using a tutorial I found on YouTube (https://www.youtube.com/watch?v=B8S_jU6iNCQ). After rendering the animation as a video (which took about 12 hours, 2 minutes 50 seconds per frame), I was faced with a bad surprise:
I really don't know what those stripes on the video are.
I tried twice and encountered the same problems both times (it's getting annoying).
I hope you can help me find a solution :) .
Thank you in advance.

    Hello. If you render a single image (with the rendering quality at 50% to save time), what does it look like?

    Did you adjust the camera settings? Did you add any nodes?

    Good evening Myuline,
    I apologize for the delay in my response.
    When I create a single image, the image is perfect; there are no stripes or cut-off areas like in the video.
    In terms of the camera, I only adjusted the limits on the depth in Display and set a distance.
    I also added nodes as shown in the tutorial: https://www.youtube.com/watch?v=B8S_jU6iNCQ
    At around 25 min 50s, 28:31, 40:32, and 46:52.
    I would also like to point out that the problem does not come from my codec because I have tried several.
    Thank you for your response Myuline ;)

      What is the export format?
      The best way to render a video is to render it in image format and then assemble these images with editing software or Blender.
      This avoids errors (maybe yours), and allows you to stop the rendering and resume it from the frame where you left off.

      Regarding the choice of image format, use PNG 16bit, RGB for colors, BW for black and white, or RGBA for colors and transparency (if you have disabled the "sky" for compositing; otherwise, it’s useless). Set the compression to 100%. And I recommend storing all these images in a subfolder of the project.
      Moreover, it’s preferable to put each project in a separate folder to avoid mixing them up. :)

      Hello Myuline,
      I will do what you said, I will first render the images (in PNG format) and then assemble them with another software.
      Thank you very much Myuline ;)

      I forgot to mention: the best solution to assemble images into a video if you don't have advanced (paid) editing software is VirtualDub. Search on Google, the manipulation is found in two seconds.
      Otherwise, you can use Blender's sequence editor, it's even easier. But I admit I had some color issues when I used solid backgrounds. It may have been resolved since then, but I now have a real editing software anyway, so no need for additional processing.

      Thank you :)
      But the rendering time for a frame is 5 minutes and 50 seconds, so do you know how to reduce the rendering time of a frame without too much affecting the quality?
      My resolution is 1920x1080 and at 100%.
      Sample: render 100 and preview 25.

      Choose a lower quality export format (JPEG), reduce the compression (slightly faster when creating the image, but it will be much heavier). Or alternatively lower the rendering quality.

      In any case, quality will be affected.
