Course Introduction：You can save the animation by recording HTML5canvas animation and encoding it into a video file. First, use the MediaRecorder API to record the canvas output, obtain the stream through canvas.captureStream(), create a MediaRecorder instance and collect data blocks, and finally generate a downloadable WebM video. Secondly, if you need higher quality or specific formats, you can export frame images (PNG/JPEG) and synthesize videos through tools such as FFmpeg. In addition, pay attention to performance and file size, appropriately limit frame rate, select compression formats, and consider the backend processing of long videos. The two methods have their own advantages and disadvantages, and choose according to your needs.
