Audio Formats for Video Editors: Complete Guide
Video editors deal with audio constantly but rarely get trained on audio formats. Mismatched sample rates, incompatible codecs, and massive file sizes cause real problems in video workflows. This guide cuts through the confusion.
Best Audio Formats for Video Editing
Use WAV for editing. Period. WAV is universally supported in Premiere Pro, DaVinci Resolve, Final Cut Pro, and every other NLE. Use 48 kHz sample rate — this is the video industry standard, not 44.1 kHz. Use 24-bit depth for the best quality. Import MP3 or AAC music tracks as-is — your NLE will handle them. But for recorded dialogue, sound effects, and original audio, WAV at 48 kHz / 24-bit is the professional baseline.
Sample Rate: Why 48 kHz for Video
Video uses 48 kHz audio. DVD, Blu-ray, broadcast TV, YouTube, and Vimeo all use 48 kHz. If you record at 44.1 kHz, your NLE must resample it. This adds processing time and can introduce subtle artifacts in cheap implementations. Set your recording device to 48 kHz before you start. If you receive 44.1 kHz audio from a music library, most NLEs handle the conversion automatically. But native 48 kHz is always cleaner.
Handling Music and Sound Effects
Stock music often comes as WAV or MP3. Either works in your NLE. For the best quality, download WAV versions when available. Sound effect libraries typically offer WAV at 48 kHz — import them directly. If you receive audio in unusual formats (OGG, FLAC, WMA), convert to WAV first. Do not waste time troubleshooting format compatibility inside your NLE. Convert once and move on.
Export Audio Settings
For YouTube and web: AAC at 256 kbps is the standard. YouTube re-encodes everything anyway. For broadcast: PCM WAV at 48 kHz / 24-bit. Follow your broadcaster's spec sheet exactly. For podcast episodes extracted from video: MP3 at 128-192 kbps. For client delivery: Match whatever they specified. When in doubt, deliver WAV alongside the video and let them convert.
Common Audio Problems in Video
Audio drift: Mismatched sample rates cause audio to slowly go out of sync. Ensure all sources match your timeline's sample rate. Missing audio: Your NLE may not support the codec. Convert to WAV. Pops and clicks at edit points: Add short crossfades (2-5ms) at every audio cut. Level issues: Normalize dialogue to -16 LUFS for web or -24 LUFS for broadcast. Use a loudness meter, not peak meters.
