This article explains how to use HeSoft Doc Batch Tool to batch remove audio from multiple videos, leaving only the visual content. It is suitable for processing course materials, surveillance clips, product showcase videos, editing assets, and other video files that need to be uniformly muted. Combined with software interface screenshots, the article illustrates the complete workflow from selecting the video tool, entering the audio removal function, adding files, importing folders, setting the save location, to starting the process, helping users reduce repetitive operations and improve batch file processing efficiency.
In daily office work, content organization, and video material archiving, you often encounter this problem: you have many video clips whose visuals need to be retained, but the ambient sound, voices, background music, or noise in the original videos are unsuitable for continued use. If you open video editing software for each file, manually mute them, and export them one by one, it's not only time-consuming but also prone to missed files. Especially when dozens or hundreds of mp4 videos need to have their sound removed uniformly, manual processing is extremely inefficient.
This article aims to solve the problem of "batch deleting audio from many videos, keeping only the visuals." Using the video tool features in HeSoft Doc Batch Tool , you can add multiple videos to a processing list at once and then execute the "remove video audio" operation uniformly. It is positioned as office software, focusing not on complex editing but on helping users process files in batches, reduce repetitive work, and improve processing efficiency.
Applicable Scenarios: When is it suitable to batch remove video audio
Batch deleting audio from videos is suitable for many office and content processing scenarios. As long as your goal is to keep the visuals and remove the audio, you can consider using this batch processing method.
- Organizing course or training materials: Screen recordings, classroom recordings, and demo videos contain noise, chatter, or voices not intended for public disclosure and need to be uniformly muted before being used for courseware or internal materials.
- Processing product demonstration videos: E-commerce, corporate promotion, and equipment display videos only need to retain the visuals, with dubbing or background music to be added later.
- Archiving surveillance, inspection, and record-type videos: The visuals have preservation value, but the audio is meaningless or involves privacy and needs to be removed before archiving.
- Preprocessing editing materials: The original audio in video footage is not needed. Before importing into other editing projects, generate silent video versions in batch first.
- Reusing social media platform assets: The visuals of some footage are usable, but the original background music is unsuitable for continued publication. Audio can be removed in batch before proceeding with subsequent editing.
Compared to processing videos individually, the advantages of batch video muting are: selecting multiple files at once, setting a unified output location, and executing the processing task centrally. For office staff, operations personnel, training material administrators, and short-video material organizers, this method aligns better with daily file processing habits.
Effect Preview: What changes before and after processing
Before Processing: Multiple video files all contain original audio
The image below shows the list of video files before processing. You can see multiple mp4 videos in the folder, such as city walk.mp4, d.mp4, Video test 2.mp4, Video test 12.mp4, Video test 13.mp4, Video test 14.mp4, Video test 15.mp4, etc. Before processing, these videos usually still retain their original audio tracks, and you will hear on-set sounds, background music, voices, or other audio content during playback.

If you only need to process one or two videos, using a regular media player or editing software to manually mute them might be acceptable. But when the number of videos is large, opening, setting, and exporting each file leads to repetitive steps and is prone to errors. Batch deleting video audio is precisely for consolidating these repetitive operations into a single task.
After Processing: Visuals preserved, no sound during playback
After processing is complete, the output videos still retain the original visual content. The files play normally, but the audio portion will have been deleted. That is, the video still appears to be the original visual material, only without sound during playback. This processing result is more convenient for subsequent needs like redubbing, adding new background music, or creating silent display assets.
It is important to note that deleting audio does not mean deleting the video visuals, nor does it convert the video into an image sequence. Its core result is: the video file remains a video, just with its audio content removed.
Operation Steps: Using HeSoft Doc Batch Tool to remove audio from videos
Below, following the operation sequence shown in the software screenshots, is how to complete batch video muting. The entire process can be understood as: enter the Video Tools function area, select "Remove Audio from Video," add the video files to be processed, set the save location, and finally start processing.
Step 1: Open the software and enter the "Video Tools" category
After launching HeSoft Doc Batch Tool , you can see multiple file processing categories in the left function bar, such as File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. Since this task involves processing video files, you need to click "Video Tools" on the left first.
After entering Video Tools, the main interface will display multiple batch processing functions related to videos. As seen in the screenshot, "Remove Audio from Video" is located in the video tools function list, indicating that this feature's purpose is to batch delete audio from video files.

The purpose of this step is to enter the functional area specifically for processing video files, from among the many office file batch processing capabilities. The expected result is: finding and clicking the "Remove Audio from Video" function card in the main interface to enter the corresponding batch processing page.
Step 2: Select the "Remove Audio from Video" function
In the video tools list, click "Remove Audio from Video." The function description shown in the screenshot states that it is used to "batch delete audio from video files." This aligns perfectly with the goal of this article: not changing the user's need for the visuals, but removing the audio from the original video.
After clicking this function, the software will enter the specific task page. The current function name will be displayed at the top of the page, and the process area will show multiple steps, including selecting records to process, setting the save location, and starting processing. This process design is more suitable for office batch tasks: first confirm the input files, then confirm the output location, and finally execute uniformly.
Step 3: Add the video files from which you want to remove audio
After entering the "Remove Audio from Video" page, the first thing is to add the videos to be processed. In the screenshot, there are two main entry points on the upper right of the page: "Add Files" and "Import Files from Folder."

- Add Files: Suitable for selecting one or more specific video files from a location.
- Import Files from Folder: Suitable when videos are all located in the same folder and you need to import the entire folder's contents at once.
If your videos are scattered in different folders, you can use "Add Files" multiple times; if they are already organized in one folder, using "Import Files from Folder" is more convenient. The example list in the screenshot has already imported multiple mp4 files, including surf.mp4, Video test 13.mp4, Video test 15.mp4, Video test 16.mp4, etc.
The purpose of this step is to add all videos that need batch muting to the processing queue. The expected result is: the records of files to be processed appear in the software table, displaying information like serial number, name, path, extension, creation time, modification time, etc., for user verification.
Step 4: Check the file list to avoid missing or wrong selections
After adding files, it's not advisable to proceed to the next step immediately. First, check the file names, paths, and extensions in the processing list. As seen in the screenshot, there is an operation column on the right side of the list, with a delete icon next to each record; a "Clear" button is available on the upper right, and the table area also provides "Filter," "Sort," and other buttons.
This information helps you do a final confirmation before starting processing:
- Confirm if the file count is correct, for example, the screenshot bottom shows a record count of 8.
- Confirm if the path is the target folder, to avoid importing videos from the wrong directory.
- Confirm if the extension matches the video files to be processed, for example, the extension in the screenshot is mp4.
- If a specific video doesn't need processing, use the delete action in its row to remove it from the list.
- If the list was imported incorrectly, use "Clear" and re-add.
The purpose of this step is to reduce the risk of incorrect processing. While batch processing is efficient, selecting the wrong files will also impact results in batches. Therefore, checking the list before proceeding is a very important office processing habit.
Step 5: Click "Next" and set the save location
After confirming the videos to be processed are correct, click the "Next" button at the bottom of the page. According to the interface flow, the next stage is "Set Save Location." This step is used to decide where the processed video files will be saved.
It is recommended to set the output location to a separate folder, such as "Silent Video," "Audio-Removed Video," or a dedicated project output directory. This offers two benefits: first, it makes it easy to distinguish between pre- and post-processing files; second, it's easier to find the resulting files for subsequent checking, uploading, archiving, or re-editing.
Since batch deleting audio generates processed video files, it's advisable not to set an overly cluttered output location or mix them with other project materials. For office collaboration scenarios, a clear save path can reduce misunderstandings when transferring files between colleagues.
Step 6: Start processing and wait for the task to complete
After the save location is set, proceed to the "Start Processing" stage in the workflow. At this point, the software will process the videos one by one according to the records in the list, deleting the audio from the videos. The more videos and the larger the files, the longer the processing time may be. It is recommended to wait for the software to finish the task before performing subsequent operations.
During processing, try not to move the original video files, nor delete the source files being processed. If the original files are located on an external hard drive, USB drive, or network directory, it's also recommended to maintain a stable connection to avoid read failures midway.
Step 7: Check if the output videos have been muted
After processing is complete, open the save location and randomly play several output videos for checking. Focus on confirming two things: first, whether the video visuals play normally; second, whether there is no original audio track during playback. If the visuals are normal and there is no sound, it means the goal of batch deleting video audio has been achieved.
If these silent videos later require dubbing, background music addition, or publishing to a platform, you can continue editing using other tools. The focus of the processing steps in this article is to first remove the original audio tracks, providing clean video visual assets for subsequent work.
FAQ and Precautions
1. Will batch deleting audio affect the video visuals?
The goal of this function is to delete the audio in the video, keeping only the visuals. Under normal circumstances, the processed file remains a video, and the visual content can continue to be played. Users need to check whether the output video meets expectations and perform spot checks before formal use.
2. Can many mp4 videos be processed at once?
Multiple videos can be added to the list via "Add Files" or "Import Files from Folder." The example in the screenshot imported multiple mp4 records at once. The actual processing quantity is recommended to be arranged considering computer performance, file size, and task urgency. If there are very many videos, they can be processed in batches for easier result verification.
3. Why is it recommended to set a separate output folder?
The biggest fear in batch processing is mixing pre- and post-processing files. Setting a separate save location clearly distinguishes original videos from those with audio removed, avoiding accidental deletion of original files and facilitating subsequent batch uploading, archiving, or secondary editing.
4. What to do if a wrong import is discovered after adding files?
If only a few files were selected incorrectly, you can use the delete action for the corresponding record in the list to remove them. If the entire import was wrong, click "Clear" and then re-add. Checking the list before starting processing is key to avoiding rework.
5. Can music be added again after processing?
After the video audio is deleted, the output file becomes video material without the original audio track. If new music, dubbing, or commentary needs to be added later, video editing software can be used for secondary editing. Batch audio removal is suitable as a pre-processing step.
Summary: Replacing repetitive video muting operations with batch processing
When you need to remove audio from many videos, keeping only the visuals, you no longer need to open video editing software to mute them manually one by one. Through the "Remove Audio from Video" function in HeSoft Doc Batch Tool , you can import multiple video files at once, set a unified save location, and then batch generate silent videos.
This method is very suitable for organizing video materials, processing courseware data, pre-processing product display assets, and uniform audio removal before content publication in office scenarios. Its value lies not in complex editing, but in centralizing a large number of repetitive steps, helping users save time, reduce the risk of missed processing, and make the file processing workflow more standardized. It is recommended to organize the video folders before processing, carefully check the list after import, set a clear output directory, and then start processing.
