CapCut mobile to Instagram Reels

Shinel recommendation

Resolution: 1080 x 1920
Frame rate: 30 fps, constant
Codec: H.264
Bitrate: Bitrate preset: target 8 Mbps (8000 kbps), max 12 Mbps
Keyframes: Automatic (no setting in CapCut mobile)
Audio: AAC-LC, default bitrate, 48 kHz, stereo
Colour: Rec. 709 (BT.709), 8-bit 4:2:0, limited (TV) range
Container: MP4 with Fast Start (moov atom at the front)

Instagram Reels publishes no bitrate. This follows YouTube's published table for the resolution, which every major platform handles well. Meta re-encodes every upload, so more bitrate than this mostly adds upload time.

Estimated size: 46.2 MB for 0:45.

CapCut mobile offers bitrate levels, not a number; pick the highest level for 1080p vertical.

Common mistakes

Exporting a 16:9 timeline for Instagram Reels. Build the edit at 1080 x 1920 (9:16) from the start, or Instagram Reels adds bars or crops your edges.
Exporting at 50+ Mbps "for quality". Meta re-encodes everything and its own spec tops out at 25 Mbps for Reels and Stories; a huge file just uploads slower.
Uploading HDR (10-bit PQ/HLG) to Instagram Reels. There is no published HDR path, so colours can look washed out; export SDR Rec. 709.
Leaving phone footage at a variable frame rate. Export at a constant 30 fps, or audio drifts and motion stutters after Instagram Reels re-encodes it.
CapCut mobile only offers bitrate levels, not a number. For a strict size cap, export, then compress with HandBrake on a computer.
Higher frame rates can lower the maximum resolution offered.

For comparison, YouTube publishes 8 Mbps for 1080p at 30 fps. Example length used for sizes: 0:45.
