When playing back a 4K video, the quality is perfect. However when playing back a series of still images with a dissolve/fade between each (think typical photo slideshow), the transitions are very choppy and distracting.
I'm using TRMS Carousel as the CMS and BrightSign XT players (XT 244 and 1144). I've tried the BrightSign-supplied SD card with no improvement. According to BrightSign support, "this is the best the unit can do."
I can't believe a $700 purpose-built player is struggling to play back basic still images in 4K. Are any of you having success with a similar use-case? If so, what CMS are you using?
