In THREE.js, when using a VideoTexture to display a video on a 3D object, you may encounter issues related to resolution and streaks. These issues could be caused by various factors, including the video source, hardware limitations, and rendering settings. Below are some common solutions to address resolution and streaking problems:

  1. Check Video Source Resolution: Ensure that the video source you are using has a resolution suitable for the desired quality in the 3D scene. Lower-resolution videos may appear pixelated when stretched on a larger object in the scene. Consider using videos with higher resolutions to improve the quality.

  2. Set Video Texture Wrapping: Configure the wrapS and wrapT properties of the VideoTexture to prevent streaking artifacts. By default, textures are set to THREE.ClampToEdgeWrapping, which may cause streaks when resizing the texture to fit the 3D object. Try setting them to THREE.RepeatWrapping or THREE.MirroredRepeatWrapping instead.

    javascript
    videoTexture.wrapS = THREE.RepeatWrapping; videoTexture.wrapT = THREE.RepeatWrapping;
  3. Adjust Texture Repeat: If you set the wrapping to RepeatWrapping, you can adjust the repeat property of the VideoTexture to control how many times the video should be repeated on the 3D object. This can help prevent streaking artifacts.

    javascript
    videoTexture.repeat.set(1, 1); // Set to (2, 2) for 2 repetitions, (0.5, 0.5) for half, etc.
  4. Mipmapping and Filtering: Consider using different texture filtering and mipmapping settings based on the specific requirements of your scene. In some cases, adjusting these settings can improve the visual quality of the VideoTexture.

    javascript
    videoTexture.minFilter = THREE.LinearFilter; // or other filter options videoTexture.generateMipmaps = false; // Disable mipmapping if not needed
  5. Video Aspect Ratio: Ensure that the aspect ratio of the video matches the aspect ratio of the 3D object on which it is displayed. Incorrect aspect ratios can lead to distorted or stretched visuals.

  6. Hardware Limitations: Low-end devices or older hardware may struggle to handle high-resolution video textures smoothly. Check the performance on different devices and adjust the resolution and other settings accordingly.

  7. Render Settings: Adjust the renderer settings, such as antialiasing and pixel ratio, to improve the overall quality of the scene.

Remember that the appearance of streaks and resolution issues can vary based on the specific scene, video source, and hardware setup. Experiment with the solutions mentioned above, and find the right balance between quality and performance for your particular use case.
