When many MP4 videos need to be uniformly muted, processing them one by one with editing software is highly inefficient. This article uses HeSoft Doc Batch Tool as an example to explain how to use the remove audio from video function in video tools to batch import multiple video files into a processing list, uniformly remove the audio track, and output silent videos that retain only the visuals. The article covers applicable scenarios, processing effects, specific operation steps, and precautions, making it a reference for office workers, operations staff, and material organizers.
When organizing video footage, you often encounter situations where "the visuals are useful, but the audio is not needed." For example, street scene videos with pedestrian chatter, product demos with noisy ambient sound, screen recordings containing narration unsuitable for public sharing, or short video clips that need re-dubbing after removing the original background music. If you only have one video, manually muting and exporting it isn't too much trouble; however, if an entire folder of MP4 videos needs their audio removed, repeating the process can be a huge waste of time.
This article introduces a more efficient method for office batch processing: using the "Remove Audio from Video" feature in HeSoft Doc Batch Tool to import multiple video files at once, delete the audio uniformly, and keep only the video track. HeSoft Doc Batch Tool is an office software designed for file batch processing, suitable for tasks involving a large number of files and highly repetitive operations. For requirements like batch removing video audio tracks, it helps users save the time spent processing files one by one.
Scenarios: Why You Need to Batch Remove Video Audio Tracks
Batch video muting isn't just a simple editing need; more often, it's a fundamental process in file organization, asset standardization, and office collaboration. The following types of scenarios are quite common:
- Uniform Ingestion of Video Assets: A team has collected a large amount of shot footage. To prevent original audio from interfering with subsequent editing, they first batch-remove the sound, keeping only the usable visuals.
- Privacy and Compliance Handling: On-site video recordings may contain unrelated voices, customer conversations, or sensitive ambient sound, which need to be removed before publishing or sharing.
- Re-dubbing Promotional Videos: The original video's visuals can be reused, but the music copyright, commentary, or sound effects need replacement, so the original audio track is cleared first.
- Processing Training and Teaching Materials: Screen recordings, operation demonstrations, or classroom videos need to be converted into silent versions, making it convenient to add subtitles or re-record narration later.
- Batch Generating Silent Previews: During material review or asset filtering, only the visuals are needed, without the audio disturbing the office environment.
The common denominator in these needs is a high volume of files, with essentially the same action required for each: delete sound, keep visuals, and output the result. Using a batch processing tool to accomplish this is more suitable than exporting them individually with traditional video editing software.

Before Processing: A Folder Containing Multiple Videos to be Processed
The screenshot below shows a folder containing multiple videos. You can see files like city walk.mp4, d.mp4, hevc_8k60P_bilibili_2.mp4, Video test 2.mp4, Video test 12.mp4, Video test 13.mp4, Video test 14.mp4, and Video test 15.mp4. These are all video assets that require batch processing.
Before processing, these videos might contain original sound captured during filming, background music, environmental noise, or other audio content. If only the visuals are needed later, keeping this sound would cause interference and might even affect publishing and sharing.
After Processing: Videos Still Playable, but Without Original Sound
After completing the "Remove Audio from Video" process, the output files are still video files, and the visual content is preserved. When users open a processed video, they will see the visuals playing normally but will not hear the sound from the original video. This result is suitable for adding new voiceovers, re-adding background music, using for silent demonstrations, or archiving as silent assets.
Since the screenshots provided in this article mainly show the files before processing and the software operation interface, we recommend that users directly play and check the effect in the output directory. During the check, you can randomly select a few video segments to confirm whether the visuals are normal and the sound has been deleted.
Operation Steps: Batch Deleting Sound from Multiple Videos
The following explains the specific operation process, combined with screenshots from the HeSoft Doc Batch Tool interface. The entire process mainly involves selecting a function, adding videos, verifying the list, setting the save location, starting the process, and checking the results.
Step 1: Enter the Video Tools Section
After opening HeSoft Doc Batch Tool , first look at the left functional navigation. The screenshot shows the software's left side contains multiple categories, including Homepage, Task Flow, All Tools, File Name, Folder Name, File Organize, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, and More Tools, etc.
Since the task involves processing video files, you need to click "Video Tools" on the left. Once inside, the main area will display batch video-related functions, such as Separating Video and Audio, Removing Audio from Video, Removing Image from Video, Adding Watermark to Video, and various video format conversion functions.
The purpose of this step is to switch the operational scope to video processing. The expected result is to find the "Remove Audio from Video" function within the video tools page. In the screenshot, the description for this function card is "Batch delete audio from video files," which corresponds to the need for "one-click muting of multiple MP4 videos."
Step 2: Click "Remove Audio from Video"
In the video tools list, click the "Remove Audio from Video" function card. Upon entering the function page, the top of the interface displays the current processing task name, and the page flow starts with "Select records to process," followed by "Set Save Location" and "Start Processing."
This step-by-step interface is suitable for batch file processing: first put the source files into the list, then determine the output location, and finally execute uniformly. For tasks involving processing many videos simultaneously, a clear process can reduce the chance of operational errors.
Step 3: Add Files or Import Files from a Folder
After entering the "Remove Audio from Video" page, you need to add the videos to be processed to the list. The screenshot shows two main buttons in the upper right corner of the page: "Add Files" and "Import Files from Folder".
If you only need to process a few specific videos, you can click "Add Files" and select the files to mute from your computer. If you have already organized the videos into a single folder, you can click "Import Files from Folder" to let the software import all videos from that folder at once. For batch processing, the second method usually saves more time, especially for scenarios where dozens of videos need to be uniformly muted.
After importing the files, the software displays the records in a table. The list in the screenshot shows multiple mp4 files and includes columns for sequence number, name, path, extension, creation time, modification time, and actions. The record count can also be seen at the bottom, making it easy to confirm the number of files being processed this time.
Step 4: Verify the Imported Results and Confirm the Videos to Process Are Correct
Before batch processing, checking the file list is very important. Once the process starts, the software executes the task based on the records in the list. Importing videos that don't need processing, or missing some target videos, will lead to rework later.
It's recommended to focus on checking the following:
- Check Names: Confirm whether all file names in the list are the videos you need to mute this time.
- Check Paths: Confirm the files come from the correct folder to avoid importing videos with the same name from different projects.
- Check Extensions: The example in the screenshot is mp4. Whether other formats are supported depends on the software's actual capabilities and the current file situation.
- Check Record Count: If you expected to process 8 videos, the record count displayed at the bottom of the list should match your expectation.
- Check the Action Column: If a specific row doesn't need to be processed, you can remove it using that row's action button.
The screenshot also shows interface elements like "Clear," "Filter," and "Sort." If there's an import error, you can clear and reselect; if there are many files, filtering or sorting can assist in viewing. This allows you to eliminate problems before formally starting the process.
Step 5: Go to the Next Step and Set the Save Location for Processed Files
After confirming the list is correct, click the "Next" button at the bottom of the page. According to the interface flow, the next step is "Set Save Location." This step specifies which directory the videos with their sound removed will be saved to.
For easier management, it's recommended not to arbitrarily save output files on the desktop or mix them with the original files. You can create a dedicated output folder, such as "Muted Videos," "Audio Removed Output," or "Silent Version Videos." This allows you to quickly distinguish between original and processed videos during subsequent checks.
If these videos belong to a specific project, you can also create a directory based on the project name, such as "Product Demo_Silent Version" or "Training Assets_No Audio." Good file naming conventions can make batch processing results easier for team members to understand and use.
Step 6: Start Batch Processing
Once the save location is set, proceed to the "Start Processing" phase. At this point, the software will execute the remove audio operation for each video in the list one by one. You don't need to open or export each video individually; just wait for the software to complete the batch job.
Processing time depends on the number of videos, file size, computer performance, and the read/write speed of the disk where the files are located. During processing, it is recommended not to move the source files, disconnect external hard drives or USB drives, or close the software. For particularly large video files, you can test with a small number first, and then batch process everything after confirming the results meet your requirements.
Step 7: Play and Check the Processing Results
After processing is complete, open the output folder and select a few video segments to play and check. Key checkpoints include: Are the visuals normal? Is playback smooth? Has the sound disappeared? If the video visuals are normal and there is no original sound, it means the batch removal of video audio tracks has been completed.
If you later need to add a voiceover or background music in editing software, you can import these silent videos as base assets. Compared to using videos with their original sound, silent materials are cleaner for post-processing and make it easier to unify the audio style.
FAQ or Important Notes
1. What is the difference between batch muting and separating audio?
The result of "Removing Audio from Video" is to strip the audio from the video, keeping only the visuals. In contrast, "Separating Video and Audio" usually splits the visual and audio into different files. The need described in this article is to not have the original audio, so "Removing Audio from Video" should be selected.
2. Can MP4 files with different names be processed?
Yes. File names do not need to be uniform, as long as the videos you need to process are added to the list. The example file names in the screenshot are not identical, for instance, surf.mp4 and Video test 13.mp4 can both appear in the same processing list.
3. Why is it necessary to check the path before starting?
Many office computers store assets from multiple projects, and file names might be similar. Checking the path ensures you are importing videos from the correct directory, avoiding the mistaken processing of files from other projects.
4. If there are many files, is it recommended to process them all at once?
If the number of files is large, it is recommended to test the workflow with a few videos first. After confirming the output results and save location are correct, proceed to batch process all files. This reduces the risk of large-scale rework caused by configuration errors.
5. Can the original audio be recovered after deletion?
If you still have the original video files, you can always go back to the source files to get the original audio. Therefore, it is recommended to output to a separate folder and properly keep the original videos safe. Do not overwrite or delete important source files without a backup.
6. What are the processed files suitable for?
The processed silent videos are suitable for re-dubbing, adding background music, creating silent presentations, uploading for review, internal sharing, or data archiving. They retain the visual information while removing sound content that might cause interference or be unsuitable for distribution.
Summary: Achieve One-Click Video Muting with an Office Batch Processing Mindset
When multiple MP4 videos need their audio uniformly removed, the most important thing is to minimize repetitive work. Through its "Remove Audio from Video" feature in "Video Tools," HeSoft Doc Batch Tool integrates adding files, importing from folders, verifying the list, setting the save location, and starting the process into a clear workflow, suitable for batch processing video files in an office setting.
