Visual Pro
April 1, 2026
Uploading Instagram Reels with the wrong settings is the number one reason creators see quality degradation. Instagram re-encodes everything you upload — but if you give it the right source file, the output quality will be dramatically better.

- 🎬 Frame Rate: 30fps (60fps is accepted but re-encoded to 30fps)
- 🎥 Codec: H.264, Main Profile, Level 4.0
- 🔊 Audio: AAC at 48kHz, 128kbps stereo
- 📦 Format: MP4 container

Why Instagram Re-Encodes Your Video
Instagram re-encodes every video you upload to ensure consistent delivery across all devices and connection speeds. The re-encoding process uses H.264 at approximately 3.5 Mbps for 1080p content. If you upload at lower quality than this, re-encoding further degrades it. Upload at the highest quality you can.
