[2025 Update] What is Javplayer? How to Install and Use it

Content

Many users have likely encountered mosaic-blurred videos while watching content. Since mosaic blurring significantly impacts the viewing experience, finding a tool to remove it is crucial. Javplayer is a dedicated mosaic removal tool that many users are familiar with. However, there are still many who are unaware of its specific usage and interface settings. Therefore, this article provides a detailed introduction to how to use Javplayer and important considerations.

What is Javplayer?

Javplayer comes in a trial version and a paid version. Its mosaic restoration feature uses AI-powered calculations leveraging the CPU and GPU to blur, sharpen, and interpolate the mosaic, thereby restoring the original footage. However, for effective restoration, it is essential that the original mosaic is lightweight.

A “lightweight mosaic” refers to a mosaic grid that is large with relatively few missing pixels. This reduces errors in interpolation and correction parameter adjustments, enabling higher restoration accuracy. For images with thin mosaics, Javplayer’s restoration success rate can reach up to 90%.

Installing and Configuring Javplayer

Installing Javplayer

First, locate the official Javplayer (Javski) account on Twitter. The homepage will display a download link. Clicking the link will reveal a download button.

Configuring Javplayer

1. Basic Operations of Javplayer

① Records videos during playback or capture.

② Captures screens in real-time from players like DMM Player.

③ Opens the file browser.

④ Performs descrambling processing (requires prior installation of DeepCreamPy).

⑤ Toggles VR mode (requires selecting a split pattern in the 3D-View settings panel beforehand).

⑥ Opens the key assignment panel.

⑦ Opens the preferences panel.

⑧ Opens the 3D-View settings panel.

⑨ Opens the screen settings panel.

⑩ Opens the color correction panel.

⑪ Opens the processing settings panel.

⑫ Pauses/resumes (same as double-clicking the screen).

⑬ Seeks by moving the handle (supports horizontal swiping).

⑭ Adjusts volume by moving the handle (supports mouse wheel).

2. Preferences

① Setting to 30fps increases capture delay. For Oculus Rift and HTC Vive, use 90fps.

② Even if the toolbar is hidden, all operations can be performed using keyboard shortcuts.

3. Screen Settings

① If the video contains black borders, press the measure button and then the apply button. Measuring on a bright screen usually sets the correct values.

If the capture target includes non-black borders (e.g., status bars), manual input is required.

② Select the screen aspect ratio.

This setting is ignored when playing VR videos in 2D mode.

4. Color Settings

Holding the Shift key while adjusting R, G, or B allows brightness adjustments. Leaving these parameters at default slightly reduces load.

5. 3D View Settings

① Settings for detecting distorted or tilted mosaics. Typically set to 0.

② VR videos are displayed in “TopBottom” or “SideBySide” mode.

③ Sets the zoom ratio. The standard field of view follows the goggle angle.

④ In 3D mode, right-dragging (default key assignment) controls the camera orientation. For VR videos, configure mosaic processing in 3D mode.

The panel cannot be opened during capture or in non-3D states.

How to Use Javplayer?

Step 1. Upload the video from which you want to remove the mosaic.

Step 2. Select the mosaic-blurred areas.

Step 3. Click the “Record” button to begin processing the mosaic-blurred video.

Step 4. Locate the processed video in the “Movie” file.
