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.
