Set up your Render Texture to display video

Use a Render Texture as a video target.
Read time 2 minutesLast updated a day ago
Use a Render Texture to display your video content on the surface of multiple GameObjects that share the Render Texture or to apply post-processing effects to the video.
To display your video content on a Render Texture:
  1. Prepare your Render Texture for video.
  2. Set a Render Texture as your Video Player's target.

Prepare your Render Texture for video

To set up a good starting point for your Render Texture with video content:
  1. Click on your Render Texture to open the Inspector window.
  2. Make sure the resolution of the Render Texture matches the resolution of your video content.
  3. Set Anti-aliasing to None.
  4. Set Color Format to R8G8B8A8_UNORM. If you notice excessive banding with your Render Texture, particularly in dark areas where the color transitions look unnatural, set Color Format to R16G16B16A16_UNORM.
  5. Set Depth Stencil Format to None.
  6. Disable Mipmap.
  7. Set Wrap Mode to Clamp.
  8. Set Filter Mode to Point. Point sampling keeps the video pixel-exact where the Render Texture maps one-to-one onto pixels on the screen, which the matching resolution in step 2 provides.
    • Note
      If you scale the Render Texture on the screen instead, set the Filter Mode to Bilinear or Trilinear and enable Generate Mip Maps to avoid a shimmering effect.
  9. Disable anisotropic filtering via script: 
    renderTexture.anisoLevel = 0;
When done, your Render Texture is ready for your video content.

Set a Render Texture as your Video Player's target

To have your video play on your Render Texture, you need to set up your Video Player component to target your Render Texture:
  1. Click on the GameObject that contains the Video Player component. The Inspector window opens.
  2. Set Render Mode to
    Render Texture

    ?

    .
  3. Assign your Render Texture to Target Texture.
Your Video Player component now targets your optimized Render Texture.
