Is it possible to upload a video to a group via JS on vk?

Question

API

Is it possible to post a video to a group through api VK without running PHP scripts.
Just create a form using js and send it without saving the video file on your server.
The video.save vk.com/pages?oid=-1&p=video.save method does not state that it is compatible with Javascript. But maybe you can somehow do it, even if the request to get a link to save will be through php, but the save itself so that it does not waste my server resources and server disk space.
