I would like to create an app that combines videos and renders them on a server.
Is it possible to do this?

I've been editing videos for around 20 years now, and I just started looking into this over the last few weeks. The barrier to editing video remotely has always been latency. But with technologies like Stadia around the corner, we'll see companies make inroads to cloud-hosted video editing soon, too. Check out Google colab. You get access to free compute time, including GPU up to a certain limit, and you can process files directly from Google Drive. I'm learning Python, and it's pretty accessible. JavaScript is also big.– Jason ConradJun 23, 2020 at 2:37

Yes, it is possible. Such a concept is often called "render farm".
On the server side you could use tools like ffmpeg that can concatenate videos. To call it you could build a dedicated render service which works like a job management agent (think of sth. like Jenkins). The goal is to decouple the render jobs from whatever service/API your app talks to.
Maybe you can even use Jenkins because it has a REST API that enables you to trigger builds. Instead of a classic build job, your job will combine videos. This approach might save you some time.
However that is just a recommendation, other architectures are possible.
On the client side, there is one possible problem to be aware: all the raw video material needs to be uploaded to the server and bandwidth or uplink speed could be a limiting factor at some point.
On the server side you have to watch out for possible DoS attack scenarios and upload of malicious content.
