After the upload is completed by default Publitio will only store Uploaded video.
It will not create any version or process it.
The reason for this is many users use Publitio only to store files and processing files would take up more space than needed.
In order to get a playable version of the video, you will need to open the link for the video.
On that first request, Publitio will start processing video.
If a video was exported in streamable mp4 format for example with h.264 codec video will work in a few seconds.
MOV files uploaded from iPhone will start working in a few seconds.
If you have uploaded mp4 file optimized for desktop viewing Publitio will need to encode that video to streamable mp4 and processing time can be from few seconds to few hours it all depends how long is video.
VIdeos with a length of 90min could take up to 90min to process.
We are working on an update that will enable you to decide what to do with uploaded videos.
To understand video upload and process check following video
