There is a perception that instead of using hundreds of pictures, a single video file could be a better approach. If we talk about it globally, then yes, it is doable. However, there are several factors to consider:
- If you want the animation to function appropriately, then it must be encoded and formatted correctly. The experience can be ruined if you use the wrong format and only a few frames of the video might be shown.
- You might experience some problems in searching the specific keyframe when utilizing a video because different browsers' implementations depend on the platform and codec being used. On lots of gadgets, it won't look as smooth.
- The video quality is substantially lower, and there isn't much support for codecs other than h264.
From a code and dependability perspective, using images is a much simpler approach. The only drawback here is that occasionally, images are larger from the size perspective than well-compressed videos.
However, if you think the video approach is the most appropriate idea for you then definitely go for it. In this amazing and very interactive tutorial
