FFmpeg upscale video the honest way: the lanczos scale command for 1080p and 4K, the bitrate math that decides how it looks, and when no scaler helps.
FFmpeg 9.0 verifies TLS by default, so 'ffmpeg certificate verify failed' kills HTTPS inputs that worked on 8.1.2. Fixes: -ca_file, CA bundle, tls_verify.
How to remove background noise from video with FFmpeg: afftdn tuning, anlmdn, and the arnndn .rnnn model file that breaks in Docker, plus filter order.
ffmpeg cropdetect finds black bars on one file fine, then breaks in a batch. Sample past the intro, take the last crop line, round to even, crop per file.
FFmpeg's stream map matches no streams error means the input has no audio track. Use -map 0:a?, probe with ffprobe, and inject silent audio before concat.

How to extract frames for LLM input without wasting tokens: one FFmpeg scene-detection pass, pixel-diff dedup, an audio track, and a JSON timestamp manifest.
Firebase video processing breaks on Cloud Functions' 9-minute timeout and in-memory /tmp. Offload FFmpeg to a hosted API and write results back to Storage.
FFmpeg concat different resolutions fails with -c copy. Two fixes that work: normalize then demux, or a one-pass filter_complex concat, plus how to pick.
