This article explains how to use HeSoft Doc Batch Tool to batch convert multiple MP4 and other video files to AAC audio format. The article combines before-and-after processing effect images and the software operation interface to illustrate the complete workflow from entering the video tool, selecting "Convert Video to AAC", adding files, setting the save location, to starting the process. It is suitable for users who need to organize course audio, meeting recordings, material narration, or mobile playback audio.
In daily office work and content organization, we often encounter this problem: we have a batch of video files, but what we actually need to save or distribute is only the audio within them. For example, training course screen recordings need to be organized into audio courseware, meeting recordings need to be extracted as audio for listening at any time, and short video materials require saving background music or narration separately. If you open video software to export audio one by one, the process is not only repetitive but also prone to missed files, naming confusion, and inconsistent save locations.
This article aims to solve the problem of "batch converting many video files to AAC audio format." The tool used here is the office-software-oriented HeSoft Doc Batch Tool . Its core value is not complex editing but file-oriented batch processing: importing multiple videos at once and executing conversion tasks uniformly, reducing repetitive clicks and helping users complete work like batch video to AAC and MP4 to AAC audio conversion more quickly.
Applicable Scenarios: When is Batch Video to AAC Conversion Needed?
AAC is a common audio format that balances sound quality and file size, offering good compatibility across mobile phones, players, browsers, and multimedia systems. For office, teaching, media operations, and data archiving personnel, batch converting videos to AAC is often more convenient than keeping the full video files.
Common scenarios include: first, converting multiple MP4 course videos to AAC audio for students to listen to during commutes or offline environments; second, extracting audio separately from meeting recordings or interview videos for minute compilation or speech-to-text processing; third, batch saving voiceovers, narration, and background music from video materials for subsequent archiving; fourth, when the original video files are large and only the audio content is needed, converting them to AAC can save storage space; fifth, when multiple videos from the same folder need a uniform output format, avoiding manual conversion one by one.
From these scenarios, it's clear that the key to batch processing lies not in whether a single file can be converted, but in the ability to process many files at once while keeping the workflow clear and the results controllable. The "Video to AAC" feature of HeSoft Doc Batch Tool is well-suited for this highly repetitive office file processing need.
Effect Preview: Multiple MP4 Videos Before Processing, AAC Audio Files After
Before Processing: A Folder Containing Multiple MP4 Videos
In the example before processing, the folder contains several video files, such as Video test 22.mp4, Video test 23.mp4, Video test 24.mp4, Video test 30.mp4, Video test 32.mp4, Video test 33.mp4, etc. These files all have video thumbnails and the .mp4 extension, indicating they are still complete video files.
Using traditional methods, you would typically need to open a video conversion tool for each file, select the output format, confirm the save location, wait for the conversion to complete, and then move on to the next file. When the number of files increases to dozens or even hundreds, the repetitive operation becomes very time-consuming.
After Processing: AAC Audio Files Batch Generated with Corresponding Names
After processing is complete, you can see the original multiple MP4 videos have been converted to AAC audio files, with file names maintaining a correspondence, for example, Video test 22.aac, Video test 23.aac, Video test 24.aac, Video test 30.aac, Video test 32.aac, Video test 33.aac. This makes it easy to verify sources and convenient for subsequent archiving, playback, or uploading.
From the effect image, it's evident that the result of batch conversion is not merging or renaming files arbitrarily, but outputting each video as a corresponding AAC audio file. This is crucial for data management, especially when serial numbers for courses, meetings, or materials are already fixed; outputting with the same name can reduce the workload of manual re-organization.
Operation Steps: Using HeSoft Doc Batch Tool to Batch Convert to AAC
Step 1: Enter the Video Tools and Select the "Video to AAC" Function
After opening HeSoft Doc Batch Tool , you can see multiple office file processing entries in the left-side function categories, including File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. As the processing target is video files this time, you need to select "Video Tools" on the left first.
On the Video Tools page, the software presents various video processing capabilities in the form of function cards, such as separating video image and sound, deleting sound from video, deleting image from video, adding watermarks to video, and converting video to MP4, AVI, MKV, MOV, FLV, WMV, WebM, MPEG, 3GP, OGV, TS, MP3, AAC, OGG, and other formats. Based on the goal of this article, you should select "17. Video to AAC".
The purpose of this step is to tell the software that the output format for this batch task is AAC. After selecting the correct function, subsequently imported video files will all be processed according to this task rule. For users, this eliminates the need to set the output format individually for each video, reducing a lot of repetitive configuration.
Step 2: Add the Video Files to be Converted
After entering the "Video to AAC" page, the interface top displays the current function name, with a "Return to Main Panel" button on the left, and operation buttons like "Add File," "Import Files from Folder," "Clear," and "More" on the right. According to the screenshot, the software uses a three-step process: Step 1 is "Select records to process," Step 2 is "Set save location," and Step 3 is "Start processing."
If you need to convert only a few scattered files, you can click "Add File" and manually select multiple videos; if many videos are centrally located in the same folder, it's more efficient to use "Import Files from Folder" to add the videos from the folder to the task list at once. The screenshot shows 6 records imported, all with the mp4 extension, located in the same test folder.
The expected result of this step is to see all pending video records in the list. The list displays the serial number, name, path, extension, creation time, modification time, and an operation column. Users can confirm whether the files are completely imported before processing. If a file was added by mistake, it can be removed using the delete icon in the operation column; if you want to re-select, you can also use the "Clear" button to empty the current list before importing again.
Step 3: Check Pending Records, Confirm File Count and Format
Checking before batch conversion is important, especially when processing a large number of videos at once. The bottom of the screenshot shows "Record count: 6," indicating this task contains 6 video files. The names in the list include Video test 22.mp4, Video test 23.mp4, Video test 24.mp4, Video test 30.mp4, Video test 32.mp4, Video test 33.mp4, and the extension column shows mp4.
The purpose of checking records is to avoid mistakenly processing videos that don't need conversion and to ensure no files are omitted. For office scenarios, while batch processing is efficient, it relies on an accurate task list. Before clicking the next step, it's recommended to focus on three key checks: whether the file count is correct, whether file paths are from the expected folder, and whether the extensions match the video formats you intend to convert.
The interface also provides "Filter" and "Sort" buttons on the right side; such list auxiliary operations are helpful when dealing with many files. For instance, when many files are imported, sorting can help verify file order, and filtering can help view specific records. This article won't expand on additional functions, just note that they can assist users in checking the task list more clearly.
Step 4: Click "Next" to Enter Save Location Settings
After confirming the pending records are correct, click the "Next" button at the bottom of the page. According to the process prompts in the interface, the software will proceed to the second step, "Set save location." The purpose of this step is to specify where the converted AAC files will be saved, avoiding uncertainty about the output location after processing is complete.
For batch video to AAC conversion tasks, it's recommended to save the output files to a separate new folder, such as "Converted AAC Audio" or "Course Audio AAC." This keeps the original MP4 videos and the generated AAC audio separated, making it easy to verify and preventing accidental deletion of original files. Although the screenshot doesn't show the specific save location page, it can be reasonably inferred from the step bar that setting the save location is a necessary step before processing.
Step 5: Start Processing and Wait for Batch Conversion to Complete
After the save location is set, follow the interface flow to the third step, "Start Processing." At this point, the software will convert the video files to AAC audio format one by one based on the previously imported records. Users just need to wait for the task to finish, without needing to manually select files or click export repeatedly.
Once conversion is complete, open the set output directory to see the .aac files corresponding to the original videos. Based on the post-processing effect image, the generated result files will be presented in the AAC format and retain names corresponding to the original files, allowing users to quickly determine which video each audio file originated from.
Frequently Asked Questions and Notes
1. Will batch converting to AAC delete the original MP4 videos?
Judging from the before and after processing effects, the operation aim is to convert videos and generate AAC audio files, not to directly overwrite the original videos. It's still recommended in actual use to set the output location to a separate folder, making it easier to distinguish between original videos and conversion results and reducing the risk of operational errors.
2. Why is using "Import Files from Folder" recommended?
When all videos are in the same directory, "Import Files from Folder" is more efficient than adding them one by one. For dozens of course videos, meeting videos, or material videos, importing a folder at once can significantly reduce the time spent on repetitive file selection and aligns better with the concept of batch office processing.
3. What information should be checked before conversion?
It's recommended to focus on the Name, Path, Extension, and Record Count in the list. The Name helps verify file completeness, the Path confirms the source folder is correct, the Extension determines the file type, and the Record Count confirms the imported quantity. Once a batch task starts, if the preliminary list is incorrect, you'll have to process it again later, so this checking step cannot be omitted.
4. What are the suitable subsequent uses for AAC?
AAC is suitable for scenarios like audio archiving, mobile device playback, course audio distribution, meeting sound retention, and material audio track management. Compared to keeping complete videos, AAC audio is generally easier to transmit and listen to, and more suitable for workflows focused solely on audio content.
Summary: Replace Repetitive Exporting with a Batch Processing Approach
Batch converting video files to AAC audio is essentially a typical office efficiency problem. Converting a single video is not complicated, but when the number of files increases, repeatedly opening, selecting, exporting, and saving consumes a lot of time. HeSoft Doc Batch Tool organizes this repetitive labor into a clear process: select "Video to AAC," import multiple videos, check records, set the save location, and then start processing.
Through this method, users can convert multiple MP4 videos into AAC audio files with the same names in one go, improving processing speed and reducing the probability of missed files and naming confusion. If you are organizing course screen recordings, meeting videos, material videos, or any folder from which you need to extract audio, it is recommended to follow the steps in this article to establish a separate output directory and then use the batch conversion function to complete the MP4 to AAC audio task.
