When extracting audio from a large number of video assets, converting them one by one can take up a lot of time. This article introduces a batch processing method suitable for office scenarios: using the video-to-OPUS conversion feature in HeSoft Doc Batch Tool , you can import multiple MP4 videos into the task list at once, verify the file information, set the save location, and start the conversion. The article uses before-and-after processing screenshots and operation interface explanations to help users quickly complete the video-to-OPUS audio task.
In daily office work, course creation, content operation, and data archiving, you often encounter this problem: you have a batch of video files, but what you really need is just the audio portion. For instance, meeting recordings need to be organized into audio, training videos need to be transcribed into text, short video material needs its dubbing saved separately, or you might want to uniformly convert multiple MP4 files into OPUS audio for easier subsequent transfer and management.
If there are only one or two files, manual conversion is acceptable; but when there are many videos in a folder, converting them one by one becomes repetitive labor. Each file needs to be selected, exported, named, and saved. The steps repeat continuously, which is very inefficient and prone to errors. This article will introduce how to use HeSoft Doc Batch Tool to batch convert multiple video files into the OPUS audio format, helping users complete tasks in a way better suited for office batch processing.
HeSoft Doc Batch Tool is a tool software designed for office file processing. Besides common document processing modules, it also provides modules for video tools, audio tools, image tools, and more. Its value lies in batch processing files, reducing repetitive clicks, and allowing users to import multiple records once and execute operations uniformly. Following the sequence of screenshots, this is a complete explanation of the process for batch converting MP4 to OPUS.
Applicable Scenarios: Why Batch Convert Many Videos to OPUS
Video files are usually large in size, containing both visuals and sound. If subsequent work only requires the audio content, continuing to save the complete video increases storage and transmission costs and is not conducive to audio data management. Converting videos to OPUS audio yields files that are more convenient for archiving and playback.
The following scenarios are particularly suitable for using batch video-to-OPUS conversion:
- Meeting minutes organization: Converting multiple segments of meeting recordings into OPUS audio for easier listening to key points or performing speech-to-text conversion.
- Online course material organization: Saving the narration sound from course videos separately, making it convenient for students to listen on mobile devices.
- Short video material management: Extracting narration, background sound, and interview audio from multiple MP4 materials into audio files.
- Media data archiving: Creating audio backups of historical video material, uniformly generating .opus files.
- Cross-department file transfer: Transmitting only audio content, reducing unnecessary video information and file size pressure.
The common feature of these tasks is a large number of files, consistent processing rules, and a clear target format. Instead of opening each video repeatedly, it's better to set up a single task in batch processing software and let the software complete the conversion automatically according to the list.
Result Preview: From MP4 Video Files to OPUS Audio Files
Before Processing: Multiple Video Thumbnail Files Waiting for Conversion
The pre-processing screenshot shows a folder containing multiple video files, with filenames including Video test 22.mp4, Video test 23.mp4, Video test 24.mp4, Video test 26.mp4, Video test 27.mp4, Video test 30.mp4, Video test 32.mp4, Video test 33.mp4, etc. The icons and thumbnails indicate that these are still video files with the .mp4 extension.
In this situation, if using traditional methods, the user would need to perform the conversion for each MP4 individually. This might already be cumbersome for a dozen files, and if scaled up to dozens or hundreds, the time spent would significantly increase. The goal of batch conversion is to add all these pending videos to a task list at once and then uniformly output them as OPUS audio.
After Processing: Generating a Batch of OPUS Audio Files with the Same Names
In the post-processing screenshot, the original video thumbnails have changed into audio file icons, and the file extensions have become .opus, for example, Video test 22.opus, Video test 23.opus, Video test 24.opus, Video test 26.opus, Video test 27.opus, Video test 29.opus, Video test 30.opus, Video test 32.opus, Video test 33.opus, etc. It is clear that the output result has changed from video format to OPUS audio format.
The advantage of this output method is its intuitiveness and ease of management. The main part of the filename corresponds to the original video, so users don't need to create a cross-reference table to know which video each OPUS file comes from. For subsequent organizing, uploading, transcribing, or sending to colleagues, a unified format is also more convenient.
Operation Steps: Completing the Batch Video-to-OPUS Task Following the Interface Flow
Step One: Enter "Video Tools" on the Left Side of the Software
After opening HeSoft Doc Batch Tool , first look at the left navigation bar. You can see multiple tool categories on the interface, such as Homepage, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, and More Tools. Since the objects being processed are video files, you should select "Video Tools".
After selecting Video Tools, the main area will list video-related function cards. You can see various format conversion entries in the screenshot, including converting videos to MP4, AVI, MKV, MOV, FLV, WMV, WebM, MPEG, 3GP, OGV, TS, as well as converting videos to MP3, AAC, OGG, etc. The position marked by the red arrow is "19. Video to OPUS", with the description "Batch convert video files to OPUS format".
The key point of this step is selecting the correct function. Because there are multiple conversion formats on the same page, if the target is OPUS, you must click "Video to OPUS", not the adjacent MP3, AAC, or OGG. After selection, the software will enter the batch task interface specifically for OPUS output.
Step Two: Enter the "Video to OPUS" Task Page
After entering the task page, the top displays the current function name "Video to OPUS". The upper right area of the page has buttons like "Add File", "Import Files from Folder", "Clear", "More". The central area is the file list, and there is a "Next" button at the bottom. The process prompt at the top of the page shows that this function is divided into three steps: Select records to process, Set saving location, and Start processing.
This interface is essentially the preparation area for the batch task. All videos that need conversion must first enter this list. The list displays not only the filename but also the path, extension, creation time, modification time, and other information, making it convenient for users to verify before starting processing.
Step Three: Import Single or Multiple Videos via "Add File"
If you already know exactly which videos to convert, you can click "Add File". This button is suitable for selecting some video files from different locations, for instance, processing only a few specific MP4 materials. After adding, the files will appear in the list, arranged by number.
In the screenshot, the list already contains multiple records, and the extension column shows mp4, indicating these files have been successfully recognized as MP4 videos. For users, seeing files appear in the list means they have entered the pending processing range. The next step is just to confirm if the records are complete.
Step Four: Batch Add an Entire Folder via "Import Files from Folder"
If the videos to be converted are concentrated in one folder, it is more recommended to use "Import Files from Folder". This button is suitable for importing a large number of materials all at once, reducing the need to select files repeatedly, which aligns more with the idea of batch processing.
For example, if a project folder contains multiple video segments, users don't need to click each MP4 individually but can import directly from the folder. After importing, the software will list the eligible files in the task list. This can significantly improve efficiency, especially for batch scenarios involving course files, meeting recordings, material libraries, etc.
Step Five: Check the File Information in the List
After importing, don't rush to start conversion. It's recommended to first check the file names, paths, and extensions in the list. The table in the screenshot lists fields like Number, Name, Path, Extension, Creation Time, Modification Time, and Actions. These fields allow you to confirm whether the files come from the correct folder and if they are the video formats that need processing.
If you find a record that doesn't need conversion, you can use the delete icon in the actions column to remove it. If the import scope is incorrect, you can also use "Clear" to reorganize the list. Batch processing is very efficient, but the prerequisite is an accurate input list. Spending a little time checking before starting can avoid generating unnecessary OPUS files later.
Step Six: Click "Next" and Set the Saving Location
After confirming the pending records are correct, click "Next" at the bottom. According to the page flow, the next stage is "Set saving location". The saving destination determines where the converted OPUS audio files will be output. For easier management, it's recommended to choose a separate folder and not mix them completely with the original video files, especially when there are many files.
When setting the saving location, you can create directories based on project name, date, or purpose, such as "Meeting Audio OPUS", "Course Audio Output", "Short Video Dubbing OPUS", etc. This way, after processing is complete, users can quickly find the result files and reduce the risk of accidentally deleting original videos or confusing versions.
Step Seven: Start Processing and Check Output Results
After setting the saving location, follow the wizard to the "Start processing" stage. The software will execute the conversion based on the video records in the list and output the audio content from the videos into OPUS audio files. During batch processing, it is recommended to keep the source file locations unchanged and avoid moving or deleting videos that are being processed.
Once processing is done, open the output directory to check the results. The expected outcome is a batch of .opus files generated, with filenames corresponding to the original videos. For example, Video test 22.mp4 becomes Video test 22.opus after conversion, and Video test 23.mp4 becomes Video test 23.opus. As long as the output quantity and file extensions meet expectations, it means the batch conversion task is complete.
Common Questions and Important Notes
1. Is batch video-to-OPUS conversion suitable for all office users?
As long as your need is to obtain audio from multiple videos, this method is suitable. It does not require users to master complex audio/video parameters; the focus is on reducing repetitive work through batch importing and unified processing. It is relatively practical for personnel in administration, training, operations, content production, and data management.
2. How should I choose between "Add File" and "Import Files from Folder"?
If files are scattered in different locations, using "Add File" is more flexible; if files are concentrated in the same directory, using "Import Files from Folder" is more efficient. In practice, you can choose based on how your materials are stored, without having to stick to one method.
3. Why is it necessary to check the extension first?
The extension can help determine the input file type. The imported files in the screenshot have the extension mp4, indicating they are MP4 videos. Checking extensions helps avoid adding irrelevant files to the task, ensuring the subsequent conversion results meet expectations.
4. Where is the recommended saving location for output files?
It is recommended to save them in a separate output folder, clearly named to indicate the purpose. This preserves the original videos while allowing you to quickly find the OPUS audio results. For projects requiring long-term archiving, you can also create folders based on date or project number.
5. Should computer performance be considered during batch conversion?
Video conversion is a relatively time-consuming task. The more files and the longer the videos, the longer the processing time. After a batch task starts, it is advisable to wait for the software to finish and avoid frequently closing the program or moving source files. If the number of files is extremely large, they can be imported in batches to make it easier to check the results.
