When you need to quickly review multiple MP4, AVI, MKV, MOV, and other video contents, opening them one by one for playback is not only time-consuming but also inconvenient for organization and reporting. This article introduces a more efficient office processing method: batch extracting frames from videos and stitching them into a grid-style JPG image, generating a single image that provides an overview of the main video content. The article will use the actual interface of HeSoft Doc Batch Tool to explain applicable scenarios, before-and-after effects, specific operation steps, and common considerations, helping you quickly complete batch generation of video preview images, reduce repetitive operations, and improve file organization and review efficiency.
In daily office work, many people encounter this problem: they have a batch of video files like MP4, MOV, AVI, MKV, etc., and need to quickly check the content, select materials, submit for review, organize and archive, or show colleagues and clients an overview of the video. Playing each video one by one is not only time-consuming but also makes it difficult to form a unified and intuitive preview result.
At this time, combining multiple key frames from the video into a single grid-style JPG image is a very practical solution. Using the office software HeSoft Doc Batch Tool , you can batch generate preview images for videos, synthesizing multiple frames from one video into a single image, significantly reducing repetitive work and improving file processing efficiency. The following explains how to operate based on the actual interface flow.
Applicable Scenarios
Batch stitching video frames into grid JPG images is especially suitable for the following office scenarios:
- Video Material Sorting: Quickly determine the general content of each video without playing them one by one.
- Content Review and Proofreading: Export video preview images uniformly for convenient centralized viewing by reviewers.
- File Archiving: Create corresponding thumbnail preview images for videos to facilitate later retrieval.
- Project Reporting or Delivery: Use a single JPG image to summarize the main scenes of a video, making the presentation more intuitive.
- Batch Processing Multiple Files: Suitable for processing multiple MP4 videos at once, and can also be used for other common video formats.
Effect Preview
Before Processing: Multiple video files, such as .mp4 files, are stored on the computer; each file needs to be opened individually to view its content.
After Processing: Each video will generate a JPG preview image containing multiple frame thumbnails arranged in vertical and horizontal grids. This way, you can quickly understand the general content and scene changes of the video without playing it.
This "grid preview" format is especially suitable for batch browsing and quick filtering.
Operation Steps
Step 1: Enter the "Generate Video Previews" Function
As seen in the screenshot, the software name is HeSoft Doc Batch Tool , which is a batch processing software designed for office scenarios. After switching to Video Tools on the left, you can see multiple video processing function cards.
This time, you need to click on "Generate Video Previews". From the function description, you can also determine that this tool is specifically used to batch generate grid preview images for video files.
Operation Purpose: Enter the correct batch processing module.
Expected Result: Open the video preview generation page and prepare to import the video files to be processed.
Step 2: Batch Add MP4 and Other Video Files
After entering the function page, the top of the interface provides two entry points: "Add Files" and "Import Files from Folder". The list below will display the imported video records, including name, path, extension, creation time, modification time, and other information.
If you are only processing a few videos, you can click "Add Files"; if you want to process all videos in an entire folder at once, using "Import Files from Folder" will be more efficient. The screenshot shows that multiple MP4 files have been imported, indicating the function supports batch operations, which is very suitable for centralized file processing in office scenarios.
Operation Purpose: Add the videos that need JPG previews to the task list at once.
Expected Result: The videos to be processed are displayed in the list, allowing you to check if the file names, paths, and formats are correct.
After confirmation, click the "Next" button at the bottom to proceed to parameter settings.
Step 3: Set Grid Stitching Parameters
On the second step interface, you can see three key settings:
- Number of Vertical Images
- Number of Horizontal Images
- Percentage of Small Image Size in Cell
From the screenshot example, both the number of vertical images and horizontal images are filled in as 3, which means a 3x3 grid preview image will be generated, i.e., a single JPG containing 9 video frames.
These parameters can be understood as follows:
- Number of Vertical Images: Determines how many rows in the vertical direction of the preview image.
- Number of Horizontal Images: Determines how many columns in the horizontal direction of the preview image.
- Percentage of Small Image Size in Cell: Used to adjust the display size of the thumbnail frame within each cell.
If you want to show more video clips in one image, you can appropriately increase the horizontal and vertical numbers; if you prioritize the clarity of each frame, you can keep the numbers within a more suitable range.
Operation Purpose: Determine the stitching layout and display effect of video frames in the JPG.
Expected Result: The software generates the preview image according to the set grid number and thumbnail ratio.
After completing the settings, click "Next" to continue the subsequent processing flow.
Step 4: Set Save Location and Start Batch Processing
From the process prompt at the top of the page, you can see the complete flow also includes "Set Save Location" and "Start Processing". That is, after completing the parameter settings, you simply need to select the export directory and then start the task.
Operation Purpose: Specify the save path for the JPG preview images and let the software execute the batch process.
Expected Result: The software automatically generates a corresponding grid preview image file for each video, saved in the location you set.
After processing is complete, you can directly open the output folder to view the batch-generated JPG images.
Frequently Asked Questions or Precautions
1. Which video formats are supported?
As seen from the list in the screenshot, the example import is MP4 files. Considering the usage scenarios of the video tools, common video formats like AVI, MKV, MOV, etc., are usually involved. During actual processing, it's recommended to import first and check whether the extensions can be recognized normally in the list.
2. How to more appropriately set the number of vertical and horizontal images?
If it's just for a quick preview, a 3x3 grid is usually quite balanced; if you want to see more clips in one JPG, you can increase the number of rows and columns; if you want to ensure the individual small images are larger and easier to see, you can reduce the number of rows and columns.
3. Why is this method suitable for office scenarios?
Because it can turn the actions of playing, screenshotting, and saving one by one into a one-time batch completion. For repetitive tasks like material sorting, review archiving, and project delivery, the efficiency improvement is very significant.
4. Should I check the files before batch processing?
It's recommended to first confirm that the video file paths are normal, the files can be opened and played, and the names are easy to distinguish. This makes subsequent organization more convenient after the JPG preview images are generated.
Summary
If you want to stitch frames from video files like MP4 into grid-style JPG images for preview, sorting, review, or archiving, using HeSoft Doc Batch Tool is much more efficient than manual screenshotting. The overall process is very clear: enter the Generate Video Previews function, batch import videos, set the number of vertical and horizontal images, adjust the small image size ratio, then set the save location and start processing.
For office users who frequently handle large volumes of video files, this method of batch generating video preview images can significantly reduce repetitive work and improve file processing efficiency. It is recommended that you prepare a batch of videos to be processed, try it first with the 3x3 grid parameters, and you will quickly get intuitive and unified JPG preview results.
