This article is aimed at users who need to process multiple video files at once, explaining how to use HeSoft Doc Batch Tool to batch convert a set of MP4 videos into AAC audio. It covers usage scenarios, comparisons before and after conversion, the video tool entry in the software, adding files or importing from a folder, checking records, proceeding to the next step to set the save location, and verification methods after processing is complete, suitable for office material organization and audio archiving.
Many people face the same issue when organizing materials: they have a batch of video files, but what they really need is just the audio inside. For example, meeting recordings need to be converted into replayable audio, training videos need to be turned into learning audio, footage needs to have its on-site sound extracted, or a large number of MP4 videos need to be delivered uniformly in AAC format. Converting a single file isn't difficult; what's hard is when the quantity increases, as repetitive operations will consume a significant amount of time.
The method introduced in this article uses the "Video to AAC" feature in HeSoft Doc Batch Tool to process multiple video files at once. It is a batch processing software designed for office scenarios, focused on helping users batch process files and reduce repetitive work, rather than having them fumble through complex parameters. The following explanation is based on actual screenshots.
Applicable Scenarios: What Problems Does Batch Video to AAC Conversion Solve
When there are many video files, batch conversion to AAC mainly addresses four types of issues. The first is efficiency, avoiding importing and exporting files one by one; the second is format uniformity, ensuring all outputs are AAC audio files; the third is naming management, keeping the main part of the original filename to easily correspond with the source video; the fourth is archiving, centrally saving the audio content from videos for easier subsequent playback, backup, or delivery.
This kind of need is very common for roles in administration, HR, training, education, operations, and self-media material organization. For instance, a series of training sessions might have dozens of MP4 screen recordings that need to be sent to students for audio review; a project folder might contain multiple video clips whose audio needs to be handed over to an editing colleague; when archiving company meetings, recordings might need to be converted into AAC files that are more convenient to listen to. In these cases, a batch file processing tool is more suitable than manual one-by-one operation.
Effect Preview: From Video Files to AAC Audio Files
Before processing, the folder contains multiple MP4 videos. The screenshot shows six video files, namely Video test 22.mp4, Video test 23.mp4, Video test 24.mp4, Video test 30.mp4, Video test 32.mp4, and Video test 33.mp4. Each file has a video thumbnail, indicating the files contain both visuals and audio.
After processing is complete, the output results become AAC audio files. The file extensions shown in the screenshot are now uniformly .aac, including Video test 33.aac, Video test 32.aac, Video test 30.aac, Video test 24.aac, Video test 23.aac, and Video test 22.aac. This means the original batch of MP4 videos has been batch converted into AAC audio.
From the filenames, it can be seen that the conversion results retain the main name body of the original videos. This is very important for batch processing, because the more files there are, the clearer the correspondence needs to be. If the output filenames changed completely, manual checking would be needed later; retaining the original names allows for direct identification of the audio source.
Operational Steps: Complete Batch Video to AAC Conversion According to Screenshots
Step 1: Open the Software and Enter the Video Tools Category
After launching HeSoft Doc Batch Tool , there is a function category navigation menu on the left. As the objects to be processed are video files, you need to click "Video Tools" on the left. Under this category, the software centrally provides video-related batch processing functions, making it convenient for users to choose based on their task goals.
In the screenshot, the video tools list includes various functions, such as separating video and audio from video files, deleting audio from video, deleting images from video, adding watermarks to videos, and converting videos to formats like MP4, AVI, MKV, MOV, FLV, WMV, WebM, MPEG, 3GP, OGV, TS, MP3, AAC, and OGG. Different cards correspond to different batch tasks.
Step 2: Select "Video to AAC"
Find the "Video to AAC" function card and click to enter. In the screenshot, this function is marked with a red box and arrow, with the description "Batch convert video files to AAC format." The purpose of this step is to tell the software that the target format for this processing is AAC audio.
Special attention should be paid here not to confuse "Video to AAC" with "Video to MP3". Both might be used to extract audio, but the output formats are different. If work requirements, system requirements, or delivery specifications state AAC, the AAC function should be chosen.
Step 3: Add Videos Using "Add Files" or "Import Files from Folder"
After entering the function page, the top title displays "Video to AAC." On the top right of the page, there are two import options: "Add Files" and "Import Files from Folder." For a small number of scattered files, "Add Files" can be used; for a large volume of videos already organized in the same directory, "Import Files from Folder" is more recommended.
The example screenshot shows 6 video records have been imported, with columns visible in the table for Number, Name, Path, Extension, Creation Time, Modification Time, and Actions. The Extension column shows mp4, indicating that the files in the current list are MP4 videos. The bottom displays "Record Count: 6," meaning 6 files will participate in this batch conversion.
Step 4: Review the List to Avoid Processing Errors
Reviewing before batch processing is crucial. It is recommended to first check the Name column to confirm all files are the target videos intended for conversion; then check the Path column to confirm they are from the correct folder; finally, check the Extension column to confirm the file types match the expectations for this processing round. In the screenshot, the file paths are all located in the same folder, making them suitable for unified conversion.
If there are records in the list that do not need processing, they can be removed by clicking the delete button on the right side of the corresponding row; if files need to be reselected, the "Clear" button can be used to empty the current list before importing again. When the number of files is large, the "Filter" and "Sort" functions can also be used to assist viewing and reduce the probability of incorrect selection.
Step 5: Click "Next" to Enter Save Location Settings
After completing the list check, click the "Next" button at the bottom of the page. The process indicator at the top of the interface shows that the processing involves "Select records to process," "Set save location," and "Start processing." Therefore, the next step will enter settings related to the output location.
It is recommended to save the converted AAC files in a separate folder, not mixed with the original videos. For example, you can create folders like "Converted AAC Audio," "Project Audio Output," or "Meeting Recording AAC Version." This way, after processing is complete, you can directly open the output directory to check the results, making it convenient for compression, uploading, or handing over to colleagues.
Step 6: Start Processing and Check the Result Files
After completing the save location settings, proceed to "Start Processing." The software will execute the batch conversion according to the records in the list, converting the video files into AAC audio. Once processing is finished, open the output folder, check if the file extensions are .aac, and perform spot checks on playback quality as needed.
If the number of original videos is very large, it is advisable to first test the entire process with a small number of files, confirming the output location and format meet requirements, before executing the batch conversion on the complete folder. This reduces the risk of rework after large-scale processing.
Frequently Asked Questions and Precautions
1. Does this method only work for MP4 files?
The screenshot example imports MP4 files, so this article focuses on batch MP4 to AAC conversion. The software function name is "Video to AAC," indicating the goal is to convert video files into the AAC format. In actual use, the software's recognition and imported list display should prevail; focus on checking the extension and file path before processing.
2. Where can I find the converted AAC files?
The converted files are usually found in the save location you set. Since the process includes "Set save location," it is recommended to choose a specific output folder at this step. After processing is complete, opening that folder directly will show the audio files with the .aac extension.
3. Why is it recommended not to rename files arbitrarily?
After batch conversion, retaining the main body of the original filename facilitates management. For example, Video test 22.mp4 corresponds to Video test 22.aac. If names are arbitrarily changed before or after conversion, it increases the verification cost when later searching for the source. For batch materials, standardized naming is very important.
4. Should I back up files before batch conversion?
Backing up important original videos is recommended. Although the effect shows that conversion generates AAC audio files, any batch operation involves multiple files. For irreproducible meeting recordings, course screen recordings, or shooting footage, keeping an original backup first is a more prudent work habit.
5. Why is this considered an office efficiency tool rather than an editing tool?
The process described in this article does not involve editing operations like cutting clips, adding special effects, or adjusting subtitles, but focuses on "batch converting videos to AAC format." The advantage of HeSoft Doc Batch Tool lies in making repetitive file processing a standard workflow, suitable for office workers to quickly complete large-scale file conversions.
