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.

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.
- Export resolution is capped by the device.
- If an export fails, try a different destination such as Files, or consolidate the project first.
For comparison, YouTube publishes 8 Mbps for 1080p at 30 fps. Example length used for sizes: 0:45.
