To add TTS narration and background music to a Remotion video, generate per-scene voiceover with ElevenLabs, source royalty-free music, and render a three-layer mix with frame-accurate synchronization and audio ducking.

Background music masks TTS narration when volume levels compete. Audio ducking with smooth ramps lowers music volume during speech, organizing layers with narration on top and music as a base to prevent clipping and masking.

Yes, you can use FFmpeg to generate sound effects for Remotion compositions. This approach creates SFX accents aligned to visual events, which are then mixed with narration and music bases using frame-accurate synchronization.

The best way to sync voiceover with video scenes is structuring TTS narration per scene to match actual speech duration, then rendering multi-layer mixes in Remotion with frame-accurate synchronization for production-ready audio.

Yes, this audio mixing approach works with alternative TTS providers besides ElevenLabs. The workflow supports generating narration per scene and mixing it with SFX and music bases using Remotion and audio ducking.

To prevent audio clipping when mixing multiple layers in Remotion, organize audio into a three-layer structure: narration on top, SFX accents in the middle, and music as a base, while applying audio ducking with smooth ramps.
