AAC vs MP3 for video audio — when to use PasteGrab MP3 preset vs MP4 for editing.
Overview
AAC is the default audio codec inside most MP4 social video. MP3 is the universal audio-only distribution format. At equal bitrates, AAC often sounds slightly better than MP3.
When you extract MP3 with PasteGrab, you transcode from the host's AAC (or similar) to MP3 — pick MP3 when your toolchain requires .mp3 files.
For video edits, importing MP4 preserves original AAC audio without an extra generation.

How it works
Editing, archival, audio reference, or quick share — each goal favors different formats and quality levels.
Social clips often work in MP4; audio-only workflows favor MP3. See our format comparison guides for tradeoffs.
Select Best quality for masters, 720p for smaller files, or MP3 when you only need audio — before you preview the link.
Check resolution, bitrate, and audio tracks in your player or NLE before committing to a workflow.
Benefits
MP3 plays everywhere. AAC is standard in MP4 but less common as standalone .aac files.
AAC at 128 kbps ≈ MP3 at 160–192 kbps for many listeners.
MP4 for video edits. MP3 for audio-only samples and DJ crates.
