But, Heavy setting is great for native progressive streams because it allows for the full stream to come through with no added compression. Plex player (at least on Apple TV and in a web browser) does not de-interlace videos, so the Heavy setting does not help when channels are interlaced. For all video streams, it compresses the video down to around 3Mbps.For 720p60 content, it drops every other full frame converting 720p60 videos into a 720p30 videos.For 1080i sources, it compresses the frame down to fit into a 720p frame.For interlaced sources (480i/1080i), it drops one of the two interlaced frames to compress the frame horizontally and making it progressive.Mobile ( “High quality (30fps limit)” setting for the HDHomeRun Extend in Plex) does a lot of stuff, so I will break it out next.įor the “Mobile” transcode profile, the Extend does a few things:.Heavy ( “Highest quality” setting for the HDHomeRun Extend in Plex) leaves framerates and frames untouched, but transcodes the video to AVC H.264 format.The HDHR passes through what it gets from the antenna (MPEG-2 stream, untouched) to the client. Native ( “Original quality” setting for the HDHomeRun Extend in Plex) does not do anything to the incoming stream.Before going into the drawbacks, it’s good to see what transcode profiles there are on the Extend. The functionality works fine, but there are some drawbacks. I need this functionality because the passively cooled Plex server I built (Atom-powered) is not powerful enough to transcode videos for viewing on an Apple TV. The SiliconDust Extend units differ from the other HDHR models (Connect and Prime) in that it has built-in hardware to transcode MPEG-2 streams to AVC H264. There was one thing bugging me and it is more with the SiliconDust Extend units than Plex DVR. Here is my earlier write up about the whole setup. For the most part, the combination has been working great – especially considering that Plex DVR is still in beta. So, I have been using Plex DVR paired with two SiliconDust HDHomeruns.
