Video generation problems

I am new to video editing. Most of my videos are rejected with the reason: "Unfortunately, during the review we found one or more technical issues such as unintentional shaking, empty black or white frame, compression and/or audio issues, so we cannot accept it into our collection." Some of the rejected videos I processed with all available CapCut autocorrectors and re-submitted for moderation - to no avail. On the other hand, there are clips processed only in ClipChamp, and yes, they passed moderation successfully. The problem is that I cannot visually recognize video defects. Videos are created in TensorArt on a paid subscription model Wan 2.2, possibly in QWEN. I will be grateful if someone gives constructive recommendations (possibly other programs/services for generation/processing). Thanks in advance.
