For a vast majority of use cases, encoding is the most time consuming part of processing video. How long it takes depends on a lot variables but, generally, a short video could take a few seconds while a long video with a large file size using an advanced codec could take days.

No matter how fast stand-alone video encoding API services claim to be, they all require you to encode the entire video first before you can publish it. So there will always be some waiting period before you can make it available to your viewers. But there are innovations happening in this space which are essentially eliminating the wait time. Advancements in encoding wait time: Just-in-time encoding is an encoding process that lets you publish your videos near instantly.

You don't have to wait until the video is fully transcoded to publish it. When a viewer requests to playback a video, the transcoding process starts and bytes of the video are delivered to the viewer as soon as the first frame of the video is encoded.
