troubleshooting color problem with video textures in three.js

There seems to be a slight variation in the colors of my video texture compared to the original video.

I've experimented with different three.js encoding options, but I still notice this discrepancy.

Does anyone have any tips on how to avoid this issue? Thanks

UPDATE

You can find the current version of my code on CodePen: https://codepen.io/michaelgrc/pen/jOGEezY

this.maTexture = new THREE.VideoTexture( el.querySelector('video') );

this.monMaterial = new THREE.MeshBasicMaterial({
    map: this.maTexture
})

I'm aiming to create a stylish transition. When I click on a video, I want it to appear larger and distorted within a canvas, using some post-rendering effects.

Unfortunately, the video doesn't display properly in my three.js render because it's hosted online, as seen in the linked CodePen.

The main problem is that when you initially click on the video element in HTML, the video within the canvas shifts slightly in color, causing a noticeable shift for the user.

Here's a screen recording showing the change in tone when clicking:

Answer №1

Make sure to check the settings for your renderer, such as toneMappingExposure and toneMapping. These properties can greatly affect the overall ambiance and appearance of your project. You can experiment with different values using this helpful example before implementing them into your own project: webgl_tonemapping. Play around with the values until you achieve your desired result:

renderer.physicallyCorrectLights = true
renderer.outputEncoding = THREE.sRGBEncoding
renderer.toneMapping = THREE.ACESFilmicToneMapping
renderer.toneMappingExposure = 1.3
//Just an configuration example

If adjusting the tonemapping doesn't solve the issue, it could also be related to an environment map problem. In that case, you may find a solution in this discussion thread where someone faced a similar texture tone problem: three-js-texture-tone-issue.
