Why does Discord reject videos even when the size reads 24.9 MB?

Discord enforces a strict 25,000,000-byte upload limit. Container overhead (MP4 moov atom box, metadata, track sync tables) adds unexpected bytes after encoding. CalcBitrate automatically applies a -5% safety margin so your file never gets rejected.

What resolution is best for a 2-minute video under 25MB?

For a 2-minute video, 1080p at 30 fps delivers crisp quality (~1,450 kbps). For videos longer than 3 minutes, 720p at 30 fps is recommended to maintain high bits-per-pixel clarity without macroblock pixelation.

Should I use 1-pass or 2-pass encoding for Discord?

Always use 2-Pass Average Bitrate (ABR/VBR). Constant Quality (CRF) cannot guarantee a file size ceiling, whereas 2-pass analyzes your video to distribute data where it's needed while strictly respecting 25MB.

Why 2-Pass Encoding Is Required

Constant Rate Factor (CRF) in Handbrake prioritizes visual fidelity over file size. A 60-second video of talking heads might compress to 10MB, but high-action gameplay will blow past 60MB. To reliably hit 25MB, switch to 2-Pass Average Bitrate (ABR).

Audio Headroom Tip

For videos longer than 3 minutes, drop your audio track from 192 kbps to 128 kbps or 96 kbps AAC. Speech remains completely transparent, while freeing up hundreds of kilobits per second for your video stream.
