Learn about video processing, FFmpeg workflows, automation, and scaling tips.
Discord's limit is 10 MB free, 50 MB Nitro Basic, 500 MB Nitro. Compress video for Discord by computing bitrate from duration, then two-pass encode to hit it.
Meta ads video specs, decoded: the four ratios that actually deliver, the safe-margin math, and one FFmpeg pass that renders 4:5, 9:16, 1:1, and 16:9.
Extract last frame FFmpeg commands return the wrong frame after a fast seek. Use -sseof with -update 1, then join Veo 3 and Sora 2 clips with no seam.
Veo and Sora render only 16:9 and 9:16. Get the AI video aspect ratio math and FFmpeg crops that turn one 9:16 generation into 4:5, 1:1, and 16:9 files.
The telegram bot video size limit is 50 MB, or 20 MB by URL. Measure with ffprobe, compute a bitrate budget for a 48 MB ceiling, then re-encode or split.
Convert video to animated WebP with FFmpeg: the libwebp flags that matter, quality and frame rate trade-offs, transparent alpha, looping, and GIF fallbacks.
FFmpeg's codec not currently supported in container error is a subtitle mux failure. Fix it with -c:s mov_text, burn in bitmap subtitles, or switch to MKV.
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.
Webhooks for long running video jobs fail quietly. Use the hint-plus-reconciler pattern: verify signatures, key idempotency on job ID, add a polling backstop.
"Filtering and streamcopy cannot be used together" means your filtergraph forces a decode. Keep -c copy where it counts by splitting codecs per stream.
