Trouble rendering video from scene

Manou · August 7, 2021, 10:53pm

Hello all
I only use Editor and I created (published) a json file via ‘three.js Editor’
(the rendered function is no longer available to create an MP4 file, due to chrome updates)

does anyone know, how to get MP4 file, from the published Json file?
what other tool can replace rendered function to create MP4 file from three.js json
Thanks to help

There is no tool for such a conversion. You essentially need the same code like the editor uses for creating MP4 files.

github.com

mrdoob/three.js/blob/0179baddfcb692931256e6d8cea0f7c4c48a2a7e/editor/js/Sidebar.Project.Video.js#L69-L120


      
          		const canvas = player.dom.firstElementChild;
          
          		//
          
          		const { createFFmpeg, fetchFile } = FFmpeg; // eslint-disable-line no-undef
          		const ffmpeg = createFFmpeg( { log: true } );
          
          		await ffmpeg.load();
          
          		ffmpeg.setProgress( ( { ratio } ) => {
          
          			progress.setValue( ( ratio * 0.5 ) + 0.5 );
          
          		} );
          
          		const fps = videoFPS.getValue();
          		const duration = videoDuration.getValue();
          		const frames = duration * fps;
          
          		let currentTime = 0;

This file has been truncated. show original

The idea to use a respective library like FFmpeg and then render for each frame of the video a frame of your scene via WebGLrenderer.

This function in Editor was very practical to finalize the work
Many Thanks for your quick reply
