VAS video with subtitles

What is VAS video with subtitles?

VAS Video Subtitles is a Windows desktop tool for generating and translating subtitles.

It identifies the speech in local videos and generates editable, loadable SRT subtitles.

Main functions

• Automatically convert video audio into subtitles.
• Translate the subtitles from the source language into the target language.
• Output the original text, translation, and bilingual subtitles at the same time.
• Use large models to improve the quality of context-based translation.
• Continuous background noise is reduced through voice separation processing.
• Accelerated by NVIDIA or AMD discrete graphics cards.
• Add videos in batches and have them processed automatically in sequence.
• Edit subtitle text, as well as the start and end times.
• Save the progress and continue the task after restarting the software.
• Generate subtitles suitable for regular players and VR players.

Subtitle generation process

The software takes video files as input and saves the recognition and translation results in separate subtitle files.

External subtitles do not alter the original video; when the player does not load them automatically, it is necessary to select the SRT file manually.

VAS Usage Tutorial

1. Ensure that the computer runs Windows 10, 64-bit, or a later version.
2. Download the installation version or the installer-free compressed package from the official page.
3. Component and model preparation is carried out during the first run.
4. Click to select a file and import one or more videos.
5. Set the source language and target language for the video.
6. Check the source language, target language, or bilingual output as needed.
7. For regular content, the results of machine translation are used first.
8. For content with high requirements, large-model translation can be enabled.
9. Users with a dedicated graphics card can enable GPU acceleration in the advanced settings.
10. Click Start and wait for the queue to complete.
11. Proofread the text and timeline in the subtitle editor.
12. Regenerate the subtitle file and check it with a player.

Subtitle output type

Multiple subtitles can be output simultaneously, allowing easy switching in the player as needed.

Subtitle editing

After automatic recognition is complete, the subtitle content and timing can be modified within the software.

• Correct names, brands, and technical terms.
• Break down long sentences to increase reading speed.
• Merge subtitle segments that are too short or repetitive.
• Adjust the start and end times to avoid overlapping conversations.
• Check the numbers, amounts, units, and dates.
• Generate the SRT file again after making the edits.

Machine translation and large-model translation

Large-model translation may still misinterpret character relationships, proper nouns, and puns; manual proofreading is required before publication.

Voice separation and intelligent enhancement

Continuous music, ambient sounds, or multi-person mixes may reduce the accuracy of voice recognition.

• Voice separation is suitable for materials with persistent background sounds.
• Intelligent enhancement can serve as another approach for noise reduction and recognition.
• A clean recording does not necessarily require any additional processing.
• Aggressive processing may result in the loss of details in voices with low volumes.
• It is recommended to compare the two options using short segments before running them in bulk.

GPU acceleration and thread settings

The software supports acceleration via NVIDIA and AMD discrete graphics cards, and it is also possible to adjust the number of CPU threads.

• Enable GPU acceleration in the advanced settings.
• Ensure that the graphics card driver and available video memory meet the requirements of the task.
• A larger number of threads does not necessarily mean faster performance.
• Leave sufficient system memory available during processing.
• Insufficient memory can cause errors when loading the model.
• First, use the same video to test the time required for different configurations.

The figure of about 10 minutes per hour for processing video with the 3060, as given on the official website, is an example only and does not apply to all types of content or computers.

System requirements and platform

Price and remaining minutes

The following are the RMB rates displayed on the official website as of August 30, 2026.

Currently, the motivational video can be watched up to 10 times per day; the rules of the campaign and the final amount to be paid are indicated on the software’s real-time page.

How to understand the cost of a package?

The table shows estimates based on the website’s rules of deducting 1 times or 2 times the amount; for abnormal tasks and any subsequent adjustments to the rules, the actual balance will apply.

Multitasking and resuming transmission at breakpoints

Users can select multiple videos at once, and the software will process them in sequence.

• Use a sample to confirm the language setting before processing in batches.
• For the same batch, try to use similar audio conditions.
• Make sure that the current progress has been saved before closing the software.
• After restoring the task, check the output directory and the remaining balance.
• Do not move or rename the source video while it is being processed.

Privacy and local processing

The official website states that video and material processing is carried out locally, without the need to upload the original media to the cloud.

Functions such as balance checks, incentive-based ads, software updates, and large-model translation may still require an internet connection; their performance should be assessed based on actual network usage.

• Sensitive videos are first tested in an isolated environment.
• Do not place the output directory in a publicly synchronized folder.
• Regularly remove temporary audio and unnecessary subtitles.
• Corporate materials must comply with internal data management policies.
• Local processing statements cannot replace a thorough security review.

Subtitle copyright and distribution

Before generating subtitles, it is necessary to ensure that the user has the legitimate rights to the video, audio, and translation.

• Do not reproduce entire films or videos without authorization.
• Check the accuracy of the translation before commercial release.
• Retain the original text, the machine-generated draft, and the records of manual proofreading.
• Handle with caution when it comes to minors or private conversations.
• Do not treat automatic subtitles as legal or medical records.

Common fault troubleshooting

• If it cannot be opened, check the system version, bit architecture, and the requirement of 8GB of memory.
• When the player has no subtitles, manually load the SRT file from the same directory.
• If the subtitles appear garbled, change the player or save the encoding again.
• When the speed is low, try GPU acceleration and an appropriate number of threads.
• Close other programs to free up memory when model loading fails.
• In case of abnormal network requests, check the proxy and network settings according to the FAQ.

GitHub and open source

Currently, no official open-source repository has been found that can be confirmed as belonging to VAS video subtitles.

VAS should be labeled as closed-source Windows software; the use of local models or local processing does not mean that the product is open source.

Usage restrictions

• Loud noise, accents, and multiple people talking at the same time can reduce accuracy.
• Large-model translation can also lead to errors in facts or terminology.
• External subtitles require the player to load them correctly.
• The speed examples for GPUs are not applicable to all hardware and videos.
• macOS is not supported at the moment.
• Prices, the number of ads displayed, and the charging rules may change.
