Zencoder is a browser-based application that will enable you to encode videos into any of the most popular web and mobile formats available today. This service will be mainly usable by people who are keen on submitting a video to these sites that host media such as YouTube, and who need to comply with their format requirements.
A wealth of both input and output formats is actually supported, and the same goes for compatibility with other transcoding tools such as Mencoder and Ffmpeg.
Using this app is quite straightforward, as a dashboard will let you see which jobs are still pending and which ones are near completion at a mere glance. You can also keep an eye on the average processing time in order to see which transcoding workers are yielding the best results so far. Transcoder workers, by the way, are launched from the dashboard and once they finish their job they will go idle and be decommissioned until you need them again.
In final place, a Zencoder API is provided for those who find the service useful and wish to integrate it into any application of theirs.
