RedNote (Xiaohongshu) video size and how to export it on Mac

Updated 2026-06-11 · Runs locally — nothing uploaded

RedNote (小红书 / Xiaohongshu) is built around vertical content. For video, that means 9:16 at 1080×1920 — a landscape clip dropped in as-is shows up small and letterboxed.

FFmix’s one-click RedNote vertical, light preset fits your footage to 9:16 and caps the size so it uploads fast and survives the platform’s re-encode — all on your Mac, nothing uploaded.

Steps

  1. 1 Drag your clip into FFmix.
  2. 2 Pick the RedNote vertical, light preset (9:16, size-capped).
  3. 3 Confirm and click Start — a lighter vertical file uploads faster.

Advanced: the real ffmpeg command

This is exactly what FFmix runs. Copy it, tweak it, or just use the one-click preset.

ffmpeg -i input.mp4 -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2,setsar=1" -c:v libx264 -b:v 6M -maxrate 7M -bufsize 12M -c:a aac -b:a 128k rednote.mp4
FFmix has a one-click "RedNote vertical, light" preset

Drop a file and go — all local, nothing uploaded.

FAQ

What video size does RedNote (Xiaohongshu) use?

RedNote favors 9:16 vertical video at 1080×1920. Square 1:1 also works for feed posts, but vertical fills the most screen. This preset outputs 9:16 with a capped bitrate so it uploads quickly.

Why cap the bitrate instead of going maximum quality?

RedNote re-encodes on upload, so a lighter file uploads faster and looks about the same after processing. For an archival master, use a higher-bitrate preset instead.

Is my video uploaded to a website to convert it?

No. FFmix runs locally through the bundled ffmpeg engine; the file never leaves your Mac.
