Many video materials, during post-editing, file archiving, course production, or audio reuse, often require separating the visuals from the audio. If you open video software to process them one by one, it is not only time-consuming but also prone to missing files. This article explains how to use the video tools in office software to batch-separate multiple MP4 videos into silent video files and audio files, generating a results folder based on the original filenames to help users quickly complete batch video splitting tasks.
In daily office work and content creation, we often encounter a need like this: a folder contains dozens or even hundreds of video files, and you need to extract the sound from each video individually while keeping the video file without sound. For example, training courseware needs re-dubbing, short video material needs separate background music preservation, meeting recordings need speech audio extraction, and surveillance or on-site record videos need only the footage retained. If you manually open video editing software for each file, export audio, and export a silent video, the entire process is highly repetitive and prone to problems like naming confusion, missed processing, and non-uniform save locations.
This article addresses the specific problem of "batch separating picture and sound from numerous video files." As seen in the screenshot, the tool used is a batch file processing software designed for office scenarios: HeSoft Doc Batch Tool . It is not only suitable for batch processing common office files like Word, Excel, PDF, and images but also provides video tools. It can add multiple video files to a task list at once, then uniformly set the audio format and save location, thereby reducing repetitive work and improving processing efficiency.
Below, using pre-processing previews, post-processing results, and software operation screenshots, we will fully explain how to batch split multiple MP4 videos into silent video files and audio files. The article uses MP4 as an example, but actual operation should rely on the software interface's support and imported files.
Applicable Scenarios: When do you need to batch separate video picture and sound?
Batch separating picture and sound from videos is common in material organization, secondary content processing, and office archiving. Unlike extracting audio from a single video, the focus of batch processing is on "large quantity, unified rules, and the need for stable output." If you only process a single video occasionally, a regular player or editing tool might suffice; but when the file count is high, the value of a batch tool becomes clearly apparent.
1. Video footage library organization. Many teams centrally store shooting footage, promotional video clips, scenic videos, and product videos. Post-production personnel might need to extract sound separately for transcription, soundtrack analysis, or archiving while keeping the silent picture as visual material. After batch separation, audio and picture files can correspond by file name, making searching more convenient.
2. Course and training video re-processing. In online courses, corporate training, and meeting screen recordings, you often need to re-record commentary audio or separately hand the original video's sound to text transcription tools. Batch splitting MP4s into silent videos and audio files like mp3, aac, opus, ogg makes the subsequent workflow clearer.
3. Short video clipping and dubbing. Short video operators may collect a large number of video clips and need to separate the original audio track from the picture to add new music, dubbing, or narration. After batch separating video picture and sound, it reduces the repetitive import and export operations in editing software.
4. Office archiving and evidence material organization. Some work record videos, meeting recordings, and on-site inspection videos need to be saved as separate picture files and audio files, making it convenient for different personnel to view or review. Batch processing through office software can make file output more standardized.
Effect Preview: Multiple MP4s before processing, corresponding folders generated per video after processing
From the pre-processing screenshot, you can see the current folder contains multiple MP4 video files, such as Video test 18.mp4, Video test 19.mp4, Video test 22.mp4, Video test 23.mp4, Video test 24.mp4, Video test 30.mp4, etc. Each file is an independent video material containing both picture and sound.
If you process these videos one by one, you need to repeatedly perform the actions "open file, select export audio, select export silent video, set save path, wait for export." The more files there are, the more time-consuming the manual operation, and it's easy to forget to process one of them. The point of batch processing is to merge these repetitive steps into a single task.
The post-processing screenshot shows that the original multiple videos were output as multiple folders with the same names, such as Video test 18, Video test 19, Video test 22, etc. Opening one of the result folders, Video test 19, reveals it contains two result files: one is Video test 19.mp3, and the other is Video test 19.mp4. This means the software extracted the sound from the original video into an audio file while also retaining the video picture file.
This output method has two advantages: first, consistent file names make it easy to confirm that the audio and picture come from the same original video; second, the results for each video are placed in independent folders, avoiding the difficulty of searching when many files are mixed together. For office users needing to process dozens of video materials, this structure is more conducive to subsequent organizing, sharing, and archiving.
Operation Steps: Using Video Tools to Batch Separate Picture and Sound
The following introduces the operation flow based on the screenshot order. Since interfaces may vary slightly between versions, please refer to the current software interface for specific button names and locations. This article explains based on the functions visible in the screenshots and does not expand on button functions not shown.
Step 1: Enter Video Tools, select "Separate picture and sound from video"
After opening HeSoft Doc Batch Tool , find and click "Video Tools" in the function category on the left. As seen in the screenshot, the left side of the main software interface also includes categories like Homepage, Task Flow, All Tools, File Name, Folder Name, File Organizer, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Audio Tools, More Tools, etc., indicating its position is a batch office file processing tool rather than a single video editing software.
After entering "Video Tools," select the first option in the tool list on the right, "Separate picture and sound from video." The description below this function reads "Batch separate video files into silent videos and audio files," which aligns with the need addressed in this article.
The purpose of this step is to determine the task type. The same page also displays tools like Remove sound from video, Remove image from video, Add watermark to video, Convert video to MP4, Convert video to AVI, Convert video to MKV, Convert video to MOV, Convert video to FLV, Convert video to MP3, Convert video to AAC, Convert video to OGG, etc. Note that if the goal is to obtain both a "silent video" and an "audio file," you should choose "Separate picture and sound from video," not just remove sound or convert to audio alone.
Step 2: Add the video files to be processed
After entering the function page, the top of the interface displays the current function name "Separate picture and sound from video." The process bar shows the task is divided into 4 stages: Select records to process, Set processing options, Set save location, Start processing. The first stage requires adding the videos to be processed to the list.
In the upper part of the screenshot, there are two buttons: "Add Files" and "Import Files from Folder." If there are only a few videos, you can use "Add Files" to select specific videos; if the videos are all concentrated in a single folder, you can use "Import Files from Folder" to import them all at once. In the screenshot, 6 records with the extension mp4 have been imported, with the path located in a desktop test folder.
After importing, it's recommended to check the list information first, including name, path, extension, creation time, modification time, etc. The bottom of the screenshot shows "Number of records: 6," indicating that a total of 6 videos will participate in this processing. The right side of the list also shows a delete operation icon; if you find you've accidentally added files that don't need processing, you can remove them before starting to avoid generating unnecessary results.
After confirming the files are correct, click "Next" at the bottom of the page to proceed to processing option settings. This checking step is crucial because once the batch task starts, it will process all records in the list simultaneously; confirming beforehand can reduce rework.
Step 3: Set the output audio format
The second process page is "Set processing options." The screenshot shows the configurable item is "Audio format," with options including mp3, aac, opus, ogg, and mp3 is currently selected.
When choosing the audio format, you can decide based on subsequent use. mp3 has good compatibility and is suitable for most office playback, transcription, sharing, and archiving scenarios; aac is commonly used in some video and mobile device ecosystems; opus and ogg might also be used in specific audio processing scenarios. For general office users with no special requirements, choosing mp3 is usually more convenient because it opens easily in Windows, phones, browsers, and most transcription platforms.
It should be noted that this step sets the format of the audio file separated from the video. According to the post-processing screenshot, the software generates one audio file and one video file simultaneously; the audio file will use the chosen format, such as Video test 19.mp3. After setting, click "Next" to proceed to save location settings.
Step 4: Set the save location to avoid mixing results with original files
The third step in the process bar is "Set save location." Although the user-provided screenshot doesn't expand the save location page, it's reasonable to deduce from the software flow that the result output location needs to be specified before batch processing. It is recommended to choose a new, empty folder as the output directory, for example, create a special "Video Picture and Sound Separation Results" folder to store the results of this batch task.
The benefit of doing this: original MP4 files won't be mixed with the processing results; the output result folders with the same names are easier to view centrally; if you later need to copy them to colleagues or upload to cloud storage, you can directly copy the entire results directory. Especially when batch processing many video files, a unified save location is very critical.
From the post-processing effect, you can see multiple folders are generated in the result directory, named after the original videos. Each folder saves the corresponding video picture file and audio file. This structure is suitable for batch tasks because it maintains a one-to-one correspondence between files.
Step 5: Start processing and check the output results
The fourth step in the process bar is "Start processing." After setting the file list, audio format, and save location, you can enter the start processing stage. After the software completes the task, open the save directory to check the results.
When checking, you can verify success from three aspects: first, whether folders with the same names as the original videos have been generated in the result directory; second, upon entering a folder, whether you can see an audio file, e.g., .mp3; third, whether the corresponding video file, e.g., .mp4, has also been retained. In the post-processing screenshot, the Video test 19 folder contains both Video test 19.mp3 and Video test 19.mp4, indicating that the separation of picture and sound for this video has been completed.
If you need to use the audio further, you can import the mp3 file into transcription software, audio editing tools, or a material library; if you need to re-dub, you can import the silent video into editing software and add new narration or background music.
Frequently Asked Questions and Notes
1. What is the difference between separating video picture and sound and "Remove sound from video"?
From the video tools list, you can see the software offers both "Separate picture and sound from video" and "Remove sound from video." Their goals differ. The separation function outputs a silent video and an audio file, suitable for retaining both picture and sound materials; removing sound typically only retains a silent video and might not output a separate audio file. If you need to also save the audio, you should choose the separation function.
2. Why is it recommended to choose mp3 as the audio format?
In the screenshot, the audio format options include mp3, aac, opus, ogg. The advantage of mp3 is its strong compatibility, suitable for common scenarios like office playback, material sharing, speech transcription, and meeting archiving. If the team or platform has specified format requirements, then choose aac, opus, or ogg accordingly.
3. Should I back up the original videos before batch processing?
Although the effect picture shows the software outputs results to a new folder, it is still recommended to keep the original video files before processing important materials. Batch tasks involve multiple files, and a backup prevents accidental deletion, overwriting, or the inability to find the source file if reprocessing is needed later.
4. How to avoid confusion when file names are very similar?
The file names in the pre-processing screenshot are all "Video test" plus a number, a naming style suitable for batch processing. It is recommended to organize the original file names before importing, avoiding duplicate, meaningless, or overly long names. The post-processing results usually adopt the original file names; the more standardized the upfront naming, the easier the later search.
5. Can it only process MP4 files?
The example files in the screenshot have the extension mp4, so this article uses MP4 batch separation as an example. The software's video tools also display various video format conversion functions, but the specific input formats supported by the separation function should be based on the software's actual import and interface prompts. If unsure, test with a few files first before proceeding with large-scale batch processing.
Summary: Using office software to batch split video material, reducing repetitive export operations
Batch separating video picture and sound is essentially a typical office efficiency problem: many files, repetitive operation steps, and results needing standardized saving. By using HeSoft Doc Batch Tool 's video tools, you can uniform add multiple MP4 videos to a task list, choose "Separate picture and sound from video," set the audio format and save location, and finally complete the processing in one go.
After processing is complete, each video generates a corresponding result folder, which contains an audio file and a video file, facilitating subsequent editing, dubbing, transcription, archiving, or sharing. Compared to manual exporting one by one, this batch processing method significantly reduces repetitive work and also lowers the risk of missed processing and naming confusion.
If you are currently facing a batch of MP4 videos that need their sound and picture separated, you can first organize the source folder, then follow the steps in this article to enter "Video Tools," select "Separate picture and sound from video," import the files, and set the audio format like mp3. For users who frequently handle office files, video materials, and data archiving, mastering this type of batch processing method can make daily work more efficient, stable, and reusable.
