Video playback blurry

I want to use Stream as an e-Learning platform, I tried a short video for testing (20"), but this video is very blurry ... this quality is not acceptable. It's a just 2,2Mb mp4 file, this should be n...

Are you uploading pre-recorded content? You have to give it awhile to decode if so, it starts out very low quality and after awhile will process the higher bitrates.

Yes, I uploaded a recorded Video (2,2Mb) … waiting since 24 hours, quality is still very bad ...

Playing same Video from SharePoint works perfect … why not from the video-platform (Video or Stream)?

    I dunno, check your bit-rate in the bottom right, see what it's set too, maybe your connection is keeping it from using higher bit-rate since it's playing through a streaming service. SharePoint is just serving up the file buffered. I've had a good experience with uploaded content on Stream, so it should be able to render at or near same quality.

      Setting is on automatic, but changing to highest bitrate makes no difference.

      After about 25" it changes to an acceptable quality, not good for an 30" video ...

      Where are you based? US? Maybe a problem of the region?

        I'm thinking you might just need to upload higher quality video. 2.2meg for 30 seconds, and the fact the bitrate is very low might be the issue as it might have an issue trying to encode something so low from the start? Also I bet region might have some effect there. I would just test with a higher end video and see what happens and go from there. 

         

        Here is my 10 second video, and it's bitrate is pretty high.
