Smart Video Trimmer

Objectives

• Detect scene boundaries and silence gaps in uploaded videos
• Identify filler words and pauses using speech analysis
• Present a visual timeline with suggested trim points
• Allow manual adjustment of cut-in and cut-out markers
• Export the trimmed video using lossless concatenation

Hints

• ffmpeg's silencedetect filter can find audio gaps automatically
• Scene changes can be detected by comparing frame histograms
• Use the -c copy flag in ffmpeg for fast, lossless trimming
