Hi all , first post here, we have been trialing the sign studio software and so far its working great. Thanks a lot to Ron for tech support !

Our test pc's are intel stick pc's and after doing a search on the forum for similar issues, we have realised that the stick pc is underpowered for this application = however we have not had any issues with video playback so far.

The issue we have is that we have a scene setup with a playlist with about  7 videos 30 - 60 seconds, ranging in size from 15mc to 49 mb @ 2560 x 1600 resolution, videos run fine however after playing one video, there is a long pause were nothing plays , then the next video starts. We understand that the player pc caches the content locally so videos should play consecutively one after another, however we are finding that this is not the case.

we would like to know if this is a limitation on the underpowered player pc, or there is some setting in the playlist timeline to set transition times in between videos in the playlist ?

Also if we want to have the scene playback the playlist infinitely how do we set that ? In Scene Settings / Player Config/ duration is set to 10 by default, can we delete the numbers here and not set any numbers to make it playback infinitely ?

Thanks in advance !

for under powered devices such as Intel Compute Stick which uses Atom or Celeron processor, we often experience performance issue during video playback.  a 2560x1600 video is actually big for these class of devices unless it was compensated by reducing the frame rate or video bitrate.  not everyone will notice quality at lower frame rate and bitrate. if you are using less than 32" display, it will not be apparent at all - all the more if you are using a tablet size screen. but for those using 4k displays, it may be noticeable when watching up close.

at a first few rotation, if the gap between video is more than a second, its possible the cache is not complete. if there are alot of videos, it may take 2 or 3 rotation for the videos to cache.  if after several rotation, the gap is longer than 1 second, it would mean you media is too large for the player to load from the cache - which leads to the performance issue we are referring to earlier.

if the player does not loop continuously, that implies the player is crashing.  try with images if the playlist loops then with lighter videos (1280x720 24fps videos) and see if they work

best regards

hi admin, we have it setup running on or store front window glass which is a large display almost 3m wide @ 16:10 resolution through a projector, as that aspect ratio gives us the best coverage that we would like, thanks for clearing up how the system / player cache works - this is exactly what is happening and we understand why it has those intervals in between play lists. Yes we will will probably drop the resolution down to the next level 16:10 resolution to maintain aspect ratio, in the mean time we gout around this issue by exporting the playlist as one single video @2560 x1600, total file size is about 170ish mb, and the compute stick seems to working with this, we have had it running for 3 days straight so far, good to know we can drop the res and output a smaller file size for the cache issue - but the solution is now clear - we just need a higher grade player :-) Thank you.
