ViBatchte
New sound in the video. No re-render.
A Nelipa Tools working instrument for audio post-production.
After mixing, dubbing or localization, a new video file has to be assembled with an updated audio track. ViBatchte preserves the original video stream without re-encoding and replaces only the audio. Subtitles, chapters, metadata and other supported source data are preserved in the output file.

The new mix is ready. The final video file still has to be assembled with the updated audio track.
Opening a video editor, replacing the audio and exporting again takes time; in many workflows, avoiding picture re-encoding is not guaranteed.
Before
Traditional process
Import the video, replace the audio track, export again and verify the result. With episodic content or multiple language versions, the number of repeated operations increases.
After
ViBatchte
The original video stream remains unchanged. Only the audio part of the file is processed. Batch operations are generated automatically from the selected pairing scheme.
Who it is for
ViBatchte is a simple, boring tool for professionals — the kind you keep within reach. It just replaces the sound in a video. Quickly and exactly.
Audio post-production engineers
Prepare video files for review, approval and client delivery.
Dubbing and localization studios
Assemble multiple language versions of the same project.
Video editors
Replace audio tracks without re-encoding the picture.
Production and content teams
Prepare versioned materials for publishing and distribution.
Typical operations after mixing, dubbing and localization.
ViBatchte is used when multiple video files need to be assembled predictably with updated audio tracks.
Localization
One video file and several language versions of audio. The output is a separate video file for each language.
1 video × N languages
Episodic production
Several episodes or releases, each matched with its own final mix.
N videos ↔ N mixes
Advertising and format versions
One final mix is applied to several versions of a spot: horizontal, vertical, square or platform-specific.
N formats × 1 mix
Review builds
Prepare video files for QC, internal review, approval or client delivery.
mix → review file
Tools for preparing new video file versions.
ViBatchte focuses on one task: replacing audio tracks in video files with a minimum amount of manual handling.
No picture re-encoding
The original video stream is copied without changes. Image quality is preserved.
Batch processing
Supports 1×N, N×1, N×M and N↔N schemes for different production scenarios.
File naming builder
Flexible output file naming based on tokens and custom templates.
Task presets
Save and reuse processing settings.
Temporary file exclusion
Files can be excluded from operation planning without being removed from the task.
File and folder import
Files and directories can be imported through drag-and-drop.
Input validation
Automatic detection of incompatible or damaged files.
Operation plan preview
Before processing, paired files, output file names and processing parameters are displayed.
Container structure preservation
Subtitles, chapters, metadata and other supported source data are preserved.
A result you can predict and check. The routine moves into the interface.
Every operation is shown before it runs, and every output file can be checked against the plan. In the default mode the picture is copied as it is and never recalculated — only the sound is handled. Pairing files, naming outputs and running batches, the steps you would otherwise repeat by hand, are done in the interface.
Four file pairing schemes.
ViBatchte builds an operation plan from the files in a task. The available schemes cover one-to-many, many-to-one, all-combinations and one-to-one workflows.
Audio will be transcoded to match the container— 2 ops
- master_16x9 + mix_ru → 01-master_16x9-mix_ru-v1.mov 01:40 ~325.5 MB video: copy · audio: copy
- social_9x16 + mix_ru → 02-social_9x16-mix_ru-v1.mp4 01:40 ~193.8 MB video: copy · audio: transcode AAC 256k
- social_1x1 + mix_ru → 03-social_1x1-mix_ru-v1.mp4 01:40 ~169.9 MB video: copy · audio: transcode AAC 256k
Total: 3 ops · 05:00 · ~689.2 MB
Output file naming rules.
Name template construction
Each token represents a part of the output file name. Video inserts the source video name, Audio inserts the audio file name. Counter, date, duration, FPS, project name and custom text fields help standardize delivery.
- Token order editing
- Individual token settings
- Live filename preview
- Save template as preset
Supported platforms and formats.
- Platform
- macOS 11+ · Apple Silicon
- Video formats
- .mp4 · .mov
- Audio formats
- .wav · .aif · .aiff · .m4a
- Local processing
- Processing runs on your computer and files are never sent anywhere. The internet is needed once — at first setup.
What gets re-encoded
- Audio is re-encoded to AAC 256k when the container cannot carry its codec — MP4 + WAV is the most common case.
- The picture is re-encoded only in the modes that extend duration (Freeze frame, Black screen). In the default mode, Shortest, never.
- For speed: MOV + WAV and MP4 + AAC go through as a pure copy; MP4 + WAV transcodes the audio, roughly +5–10 seconds per minute of video.
