CapCut mobile to Instagram Stories

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

Instagram Stories 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: 15.4 MB for 0:15.

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

Common mistakes

Exporting a 16:9 timeline for Instagram Stories. Build the edit at 1080 x 1920 (9:16) from the start, or Instagram Stories 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 Stories. 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 Stories re-encodes it.
Going over the length limit. Instagram Stories: 60 seconds via API; app offers a trimmer for videos over 60 s (help); ads up to 60 minutes, split into cards.
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: 0:15.
