The Studio S01 Ffmpeg

FFmpeg generates fragmented MP4s; GPAC’s MP4Box creates DASH manifest:

| Limitation | Workaround in Studio S01 | |------------|--------------------------| | No native ARRIRAW decoding | Use arri_raw (external patch) or transcode via ARRI SDK wrapper | | No Dolby Vision RPU generation | External Dolby Encoding Engine; FFmpeg only passes through | | 10-bit H.264 software encoding slow | Use libx264 -preset ultrafast -tune fastdecode for proxies | | No closed caption burn-in (SMPTE-TT) | Use subtitles filter with ASS conversion | | No native IMF packaging | FFmpeg → MXF + separate CPL/OPL generation with imf tool | the studio s01 ffmpeg
