 # Limitations of FFmpeg VVC encoder
 
-Before encode to VVC video codec, see the limitations below.
-
-libvvenc (FFmpeg vvc version) works for:
-
-- Pixel format ⚠️ (only pixel format 10 bit is default, but you can still encode 8 bit by using vvenc params `-vvenc-params InternalBitDepth=8`)
-- Video size (auto detects, but it doesn't detect for SAR and DAR anamorphic is glitch and corrupts the video) ⚠️ (Better way to use vvencapp without FFmpeg)
-- Frame rate ✅ (auto detects)
-- MP4/TS Mux ✅ (only works for stable if it's encoded VVC with MP4 or TS on FFmpeg and mp4box for muxing still works)
-- Mux MP4/TS container from raw bitstream on FFmpeg ⚠️ (the first frame freezes may just print error messages for libvvdec when muxed and seeking in FFmpeg, use mp4box for recommendation)
-- Matroska mux ⚠️ (Only matroska mux has an experimental, causing problem of the video sync delay with audio and others for FFmpeg libvvdec. It is unofficial support)
-- Demux ✅
-- Audio with encode VVC ✅
-- Broadcasting ✅ (MPEG-TS)
-- Streaming ✅ (MPEG-DASH)
-- Bitrates ✅ (average (`-b:v`) and maximum bitrate (`-maxrate`) are only supported)
-- Passes ⚠️ (you may need get passes using vvenc params on FFmpeg VVCEasy or use vvencapp, also it is only available to use bitrate for two passes, QP supports only one pass)
-- Presets ✅
-- QP ✅
-- HDR ✅
