larsrikart Posted October 27, 2014 Report Share Posted October 27, 2014 We have a problem with playback of video with a resolution of 3840x1080 or 4096x1080 on a Watchpax2 going to two side by side 2K projectors. MP4 is encoded using Adobe Media Encoder with High 5.1 profile in 25mbit/s. If going scaling down in resolution(2500x720) and bitrate(5mbit/s) it plays back fine.. Any ideas on how to avoid scaling down? 0 Quote Link to comment Share on other sites More sharing options...
Jonas Dannert Posted October 27, 2014 Report Share Posted October 27, 2014 WATCHPAX 2 is not designed to play 4K-content. I think you're running out of hardware resources here. One way might be to pre-split, (P42 in the manual) your content into 2 1920x1080 clips and use a Video proxy instead. Otherwise a Display computer and license is required for this playback scenario. /jonas 0 Quote Link to comment Share on other sites More sharing options...
larsrikart Posted October 27, 2014 Author Report Share Posted October 27, 2014 But this is only half of a 4K playout? would it be better to enocode a full 4K and distribute over the two outputs? what would be recommended encoding settings for 4K H264? 0 Quote Link to comment Share on other sites More sharing options...
Jonas Dannert Posted October 27, 2014 Report Share Posted October 27, 2014 Vertically yes, horizontally no. And 25 Mbps is more than it can handle. /jonas 0 Quote Link to comment Share on other sites More sharing options...
Moderator jfk Posted October 27, 2014 Moderator Report Share Posted October 27, 2014 Also, keep in mind, that while two 2K movies may be the same amount of pixels as the 1/2 4K movie, running it as two movies instead of one better utilizes the available resources by spreading out the task over more processor cores, etc. 0 Quote Link to comment Share on other sites More sharing options...
