Target Size Limit Exceeded

The output file size is 16.2 MB, which couldn't fit into the selected target limit of 8.0 MB (by 102.5%).

⚠️ Why did this happen? Highly complex scenes, long videos, or format constraints (like WEBM or MP4 minimal overhead) can prevent further reduction without sacrificing all visual clarity. Try trimming the video duration or selecting a more aggressive option (e.g. Maximum Compression).
