This article is aimed at office users who need to uniformly add diagonal text watermarks to a large number of videos, introducing how to complete batch processing through HeSoft Doc Batch Tool . The tutorial includes a comparison of before and after effects, a description of applicable scenarios, video tool entry selection, batch importing of MP4 files, setting text watermarks, font size, clockwise rotation angle, tiling method, and tiling density, helping users quickly create video preview files with copyright marks.
In the process of video asset management, course delivery, client review, and internal material distribution, a common need often arises: uniformly adding diagonal text watermarks to a batch of videos. The watermark content might be "Original," "Preview," "Internal Material," or a company name, serving to inform the recipient about the video's purpose and copyright status. The problem is, if there are many videos, adding watermarks one by one using editing software involves repeatedly going through steps like importing, entering text, adjusting the angle, and exporting, which is very inefficient. Moreover, the position and size of the watermark can easily become inconsistent across different videos.
HeSoft Doc Batch Tool is a batch file processing software designed for office scenarios. Its interface provides video tools, including a "Add Watermark to Video" function. It is suitable for handling these types of well-defined, high-volume video tasks. This article will focus on "batch adding text watermarks to many video files," with a key demonstration on how to create the diagonal, tiled text watermark effect shown in screenshots.
Use Cases: Why Add Uniform Diagonal Watermarks to Multiple Videos
Diagonal text watermarks are common on preview drafts, samples, stock footage libraries, and internal files. Compared to placing a small watermark only in the bottom-right corner, a diagonally tiled watermark is distributed more widely across the frame. Viewers are more likely to notice the copyright notice, and it is also harder to remove by simple cropping. For videos that need to be shown to clients for trial viewing but are not intended for direct use, a diagonal watermark is a practical solution.
For example, a short-video team can add an "Original" watermark to unapproved material; a training department can add an "Internal Training" watermark to internal course videos; design or photography agencies can add a "For Preview Only" watermark to video samples sent for client confirmation; content operators can also add source identifiers to videos downloaded or organized in batches. As long as these videos need the same set of watermark rules, they are suitable for completion using a batch processing tool.
It should be noted that this article is not about complex editing, transitions, or subtitle creation, but about batch video processing within office software. Its advantage lies in standardized steps, minimal repetitive operations, and suitability for processing multiple files at once.
Effect Preview: From a Video Without Watermark to a Diagonally Tiled Text Watermark
Effect Before Processing
The image below shows the video frame before processing. The player indicates the video duration is about 21 seconds, and the video name is "Video test 20". The frame has no copyright marks or text overlays. If this video were sent directly to an external party, it would be difficult for the recipient to determine the file's source just by looking at the footage after saving it.
Effect After Processing
After processing, multiple instances of the word "Original" appear diagonally across the video frame. The watermarks have a red, semi-transparent visual effect and are distributed in a tiled pattern on the screen. They do not completely obscure the main subject, but persistently indicate the video is preview or original copyrighted content. For scenarios where preventing direct misappropriation of material is necessary, this effect is more reliable than a single-point watermark.
Operation Steps: Batch Setting Video Text Watermarks
Step 1: Find the Video Watermark Function in the Software
After launching HeSoft Doc Batch Tool , first observe the left-side function navigation. The screenshot shows the software includes multiple file processing categories, indicating it is not a single-purpose video application but a toolbox centered around batch office file processing. As we need to process videos this time, click "Video Tools" on the left.
After entering Video Tools, the first card in the function list is "Add Watermark to Video," with the description below stating "Batch add text or image watermarks to video files." This perfectly matches our goal: uniformly adding text watermarks to many videos. Click this card to enter the video watermarking workflow.
The expected outcome of this step is to enter the dedicated video watermark processing page, not a video format conversion page. The same page in the screenshot also shows functions like "Convert Video to MP4" and "Convert Video to AVI," but our goal is watermarking, not format conversion, so "Add Watermark to Video" should be selected.
Step 2: Batch Import the Videos to be Watermarked
After entering the function page, there are two main entry points at the top: "Add Files" and "Import Files from Folder." If the videos are scattered in different locations, you can select them in batches via "Add Files"; if the videos are gathered in one folder, using "Import Files from Folder" is faster. The screenshot shows 6 records have been imported, all with the mp4 extension, located in a Videos folder on the desktop.
The table lists the sequence number, name, path, extension, creation time, modification time, and action. Do not rush to the next step after importing; it's advisable to first check if the names and quantity are correct. For instance, the bottom of the screenshot shows "Record Count: 6," which helps confirm if any files were missed or selected incorrectly. If a particular video doesn't need processing, it can be removed via the delete button on the right side of that row; to select a different batch of files, use the "Clear" option at the top before importing again.
The goal of this step is to build the list of videos to be processed. The key to batch processing is accurately organizing the file list first; otherwise, even if the subsequent watermark settings are correct, you might process the wrong files.
Step 3: Choose Text Watermark and Enter the Watermark Content
After confirming the file list, click "Next" at the bottom to enter "Configure Processing Options." In the Watermark Type area, you can see "Text Watermark" and "Image Watermark." This tutorial aims to create a text watermark, so select "Text Watermark." Once selected, enter the desired content in the "Watermark Text" input box. The example screenshot shows "Original," so that is what will appear in the processed video.
In real office scenarios, the watermark text can be flexibly set according to the purpose. Videos for client review can use "For Preview Only"; internal training videos can use "Internal Material"; copyrighted material can use "All Rights Reserved" or a brand name. It's recommended not to make the text too long, as it will repeat when tiled, and overly long content can make the frame look cluttered.
Step 4: Set Font Size, Rotation Angle, and Tiling Method
The screenshot shows the "Font Size" switch is enabled, with a value of 30%. This means the watermark text will be displayed at the set size. For common landscape videos, a 30% font size creates a fairly noticeable copyright notice, but adjustments should still be made based on the video resolution and frame complexity.
The "Rotation Angle (Clockwise)" is also enabled, with a value of 45. This is the key to a diagonal watermark. A 45-degree watermark is visually common—it's eye-catching without occupying a fixed horizontal area. The "Original" text in the post-processing effect image is displayed at this diagonal angle.
In the "Filling Method" area, the screenshot shows "Tile" is selected. This means the watermark will repeat across the frame, rather than appearing just once. The "Tile Density" below is set to "Normal," indicating a medium spacing between watermarks. For a cleaner frame, a sparser density can be chosen; for stronger protection, a denser scheme might be considered. The actual available options are subject to the software interface; the screenshot shows density options like "Sparse, Normal, Dense."
Step 5: Proceed to the Next Step, Save, and Start Batch Processing
After configuring the watermark content and style, click "Next." The progress bar shows that "Set Save Location" and "Start Processing" follow. The purpose of setting the save location is to output the processed files to a designated directory, making them easy to distinguish from the original videos. It is recommended not to overwrite the original files, but to save them to a new folder, such as a directory named "Watermarked Videos," for easy checking and archiving.
Finally, upon entering the start processing phase, the software will process each video in the import list one by one, applying the same text watermark rules to every file. After processing completes, open one of the output videos to check if the text content, angle, font size, and tiling density meet expectations. If satisfied, the entire batch of output files can then be used for delivery, upload, or archiving.
FAQ and Important Notes
1. Will the diagonal watermark affect viewing?
The purpose of a diagonal watermark is to strike a balance between protecting the content and retaining watchability. The processed effect in the screenshot shows the watermark covers a wide area, but with a low text transparency, the main subject is still discernible. If the video is for formal release, overly dense watermarks might not be suitable; for previews and anti-theft purposes, a tiled watermark is more appropriate.
2. Will the watermark style be consistent across multiple videos?
As long as multiple videos are imported in the same task and the same set of processing options is used, the software will apply the same rules for batch processing. This is precisely the value of batch office software: reducing errors from individual settings and ensuring a unified identifier across the same batch of videos.
3. Why check the file list before processing?
Once batch processing starts, the same operation will be executed on all records in the list. If a video that shouldn't be watermarked is mistakenly included, it will need reprocessing later. Therefore, checking the file names, paths, extensions, and record count in the first step is very important.
4. Can formats other than MP4 be processed?
The files pending processing shown in the screenshot are in MP4 format, and the software's Video Tools page also displays various video-related functions. The actual video formats that can be processed should be determined by what the software's current version can recognize and import. For important files, it's recommended to test with a small number of samples first.
Summary: Diagonal Tiled Text Watermarks Are Suitable for Batch Video Copyright Protection
If you need to add a uniform diagonal text watermark to a large number of videos, using HeSoft Doc Batch Tool is more efficient than manual editing. The entire workflow can be summarized as: enter Video Tools, select "Add Watermark to Video," batch import videos, select Text Watermark, enter the watermark content, set the font size, 45-degree rotation, tiling method, and density, then set the save location and start processing.
This method is especially suitable for sample reels, preview drafts, internal materials, and copyrighted assets. It is recommended to test the watermark effect on one or two videos first. After confirming the text content, size, and density are appropriate, then execute the process for the entire batch. This way, you can protect video content while significantly reducing repetitive labor, making video watermark processing more aligned with efficient office workflows.
