I am currently planing the total cost of hosting my videos on azure. After studying the [pricing](https://azure.microsoft.com/de-de/pricing/details/media-services/) I noted that the costs for storing the data is actually much lower than the price for converting them. Unfortunately I will have many videos, but they won't be watched a lot. Therefore the relative cost for converting them to different formats is too high for me. 

Now my question, do I actually need to convert the videos to different formats or wouldn't it be possible to send the video directly from the storage to the browser?
