We recently made some changes in the uploader in order to optimize the delay in putting online a video.
In the past, when we received a video, we directly converted it into SD, HD, and FHD and only put them online once we finished converting into these three formats.
Now that we receive a video, we directly convert it into SD and HD and put it online. The FHD encoding needs much more time and so, we encode the video later on, when one of our encoding machines is available.
It's normal that once uploaded, you only have the SD and HD quality, but the FHD will also be available later on, don't worry.
