I'm trying to decide between browser-based (client-side) and server-side processing for adding captions to short video clips, specifically around 20 seconds long. Is using in-browser processing a practical choice, or would I be better off sticking with server-side methods?

Using something like FFmpeg.wasm for client-side works well for short video clips, but I've seen it struggle on mid-range devices which can lead to frustrating user experiences. If you're worried about cost, consider using a job queue for processing asynchronously instead!
It really depends on what you're looking for! Server-side means more control, but it comes with costs since you'll need to handle the processing yourself. On the flip side, client-side processing can be great for privacy since users manage their own devices, but you might run into issues with users on lower-end devices.
For short clips, client-side is the way to go; it's budget-friendly and lets you leverage user hardware. Just beware of potential performance issues on older devices, which can cause browser tabs to freeze. A potential workaround is using the canvas API for rendering captions instead.
For short clips like 20 seconds, I think browser-based processing is a fantastic option for burning captions. It's quicker since users don’t have to upload videos, cheaper since you avoid server costs, and beneficial for privacy. Just keep in mind, performance can really vary based on the user's device. For heavier tasks or when you need consistent output, server-side might be the way to go.
If it's just about adding captions, definitely check out WebVTT. It's designed to be easy and efficient for that purpose!
Yeah, WebVTT is a solid choice for simple text overlays. It keeps things smooth without heavy processing!
