StreamYard max file size: 8 GB per single upload.

The details

StreamYard's maximum file size for a single upload in 2026 is 8 GB. Most creators never hit this ceiling — codec efficiency means even a long, high-quality clip rarely exceeds it.

When the limit actually matters: (1) you're uploading uncompressed or ProRes master files instead of delivery-spec H.264. (2) You're using an old codec (H.264 baseline profile) that bloats bitrate without quality gain. (3) You're working in 4K HDR for a platform that only renders 1080p — you're shipping pixels the player never uses.

Codec + format requirements StreamYard prefers: audio at AAC stereo, H.264 video (High profile, Level 4.0 or higher), MP4 container. HEVC/H.265 uploads work on most modern platforms but transcode slower on the server side, which can delay the post going live.

Note: MP4 recording with overlays burned-in; raw separate-track export not available.

Common upload failures and fixes: - "File too large" error: re-export at CRF 23 (H.264) instead of constant bitrate. CRF preserves visual quality and cuts file size 40-60% versus high-bitrate CBR. - "Unsupported format": StreamYard wants MP4. If you exported MOV or MKV, re-mux without re-encoding (ffmpeg `-c copy`) — no quality loss. - Upload hangs: chunked uploads often fail when the connection is unstable. Wired ethernet or a stable 50Mbps+ uplink resolves most large-file uploads.

Frequently asked questions

What's the maximum file size on StreamYard?

8 GB per single upload as of 2026-05.

Why is my StreamYard upload failing?

Most "upload failed" errors on StreamYard aren't file-size — they're codec or container issues. Re-export as H.264 MP4 first; only worry about file size if you're over 8 GB.

Can I upload 4K to StreamYard?

Yes, up to the 8 GB cap. StreamYard will downscale to its native player resolution, so you're paying upload bandwidth for pixels the viewer never sees unless you specifically need future-proofing.

How do I compress a video for StreamYard without losing quality?

Use H.264 with CRF 18-23 (visually lossless to nearly-lossless), AAC audio at 192-256kbps. This typically cuts file size 40-60% versus a high-CBR master with no visible quality loss.
