The repetitive part
A group of videos may need the same music bed, narration, or recurring sound. Repeating the import, volume, timing, and export setup for every file makes a simple audio decision slow.
When batch processing helps
Add Audio can mix the selected track with existing source audio across the batch, with shared volume and short-audio behavior.
Ways to handle the job
Mix every video in an editor
An editor gives detailed mixing control, but each source needs its own timeline and export for the same recurring track.
Mix with audio scripts
Command-line mixing can process a folder, but duration, looping, volume, mapping, and silent-source cases need explicit handling.
Use BlinkClip visually
BlinkClip applies one selected track with consistent added and original volume settings, and can stop or loop shorter audio.
Step by step
Select the videos
Drag videos into BlinkClip or use Select Videos to choose the files that need the same change.
Choose Add Audio
Select Add Audio and choose the music, narration, or other audio file.
Choose Mix
Keep the existing soundtrack, set original and added volume, then choose whether shorter added audio stops or loops.
Review the batch
Confirm the selected files, start processing, and wait for BlinkClip to finish the repeated job.
Check the results
Open the processed files in Finder and review representative outputs before replacing or sharing originals.
Useful checks
- Check speech clarity when adding music.
- Test a video with source audio and one without it.
- Review the end of videos when the added track is shorter than the source.
Common questions
Does Add Audio keep the original soundtrack?
Use Mix mode to preserve and combine the source audio. Use Replace mode when the source soundtrack should be removed.
What if the added audio is shorter than the video?
Choose whether the added track should stop or loop while the video continues.
