    Sarah, MP4 is playing fine on RV. I am using Adobe Media Encoder. I believe the problem is in the Old Editor. That twitch at the end of a looping video used to be a thing of the past, but it looks like RV has solved this problem since. Anyway, back then I had this workaround for looping videos. I was making a simple webpage just for the video and pulling that page to a presentation with the Web Page Widget. I never tried Custom HTML Widget, but that might work too. This way I made looping videos work seamlessly on RV.

    As I said though, we only have one presentation currently using the old editor and it's not our decision, every other sign has the new editor. This is happening on all our signage with video :( But I will definitely try out the web page widget workaround.

    I just ran a test of a looping MP4 video (new editor, video widget, RV Storage) and I see no problem, no twitching at the 'seam' no nothing. And I am using here crappy 1st gen. Intel ComputeStick. Which makes me question one of those: players, files, implementation. Video link I am using (in case you want to test it yourself: https://storage.googleapis.com/risemedialibrary-77d65575-178b-499c-a476-eb66c5424a89/Acme%20Sign%20Co/misc/w5ene7jfymhnr9ovzk36.mp4

    For some reason, most of our mp4s were starting to display that white screen and "file is downloading" in the center in the last few months, so it's why I changed everything to webm. Basically my process was making the videos in Adobe After Effects, exporting through media encoder to mov, Handbrake to convert that to mp4, and then zamzar to convert that to webm. I'm not the brightest when it comes to video files/exporting and whatnot, but perhaps I'm making it more complicated than it needs to be?

    Or it might be in part due to us not having these on Rise storage? My boss has been thinking about getting storage and/or getting a Professional account but I'd want to know for sure if it would correct this issue.

    Our players are Intel NUCs with Windows 7 Enterprise.

    This is quite strange that you making videos in Adobe After Effects, exporting trough Adobe Media Encoder and then using some 3rd party software to convert the files. Adobe Media Encoder is perfectly capable to convert/encode MP4 videos, and it is one of the best for encoding MP4 videos in my opinion. Why do not you use it for your MP4 videos? Also with this plug-in http://www.fnordware.com/WebM/ you can convert to WebM in Media Encoder directly. This is what I do. You do not need RS Storage for your videos, any other reliable online hosting will do, but I recommend getting it anyway because it is good and reliable although a bit cumbersome ;). Could you, Sarah, share with me one of those video files you are getting problems. I want to test it. Also, do you know what processor is powering those NUCs, model #?

    Oh! I guess I haven't been using Media Encoder. I just export right from AE; no wonder I only had the option of mov. I guess I just kept doing what I've been doing and once I found a solution just stuck with the process :/ As I said, I'm not really knowledgable in the whole file-type/exporting deal especially when it comes to videos. Could you take a look at this screenshot? Is this the correct export info?

    Here's a direct link to an mp4 I know we had a problem with on our new sign: https://buffalo.box.com/shared/static/rmji1jbhtfmuielxzewchkitbqyk0bqi.mp4 (said that "file is downloading" prompt)

    I won't update the file on that link with a newly exported one until I hear your response

    So your video is playing (looping) nicely on my Intel Compute Stick (win10, wired connection, Pro player). here is the link from my RS Storage (in case you want to test it) https://storage.googleapis.com/risemedialibrary-77d65575-178b-499c-a476-eb66c5424a89/Acme%20Sign%20Co/misc/harrimancafe-2017.mp4

    I do not create videos, so I cannot tell much about the exporting settings for After Effects, but I use the standard H.264 settings in Media Encoder. I often disable sound and I recommend downscaling to 720p for 1080p displays. Files get smaller, easier for players to process, and 'the crowd' will not notice the difference or appreciate it anyway.

    Seems exporting H.264, match source - medium bitrate works well, but there's still a flicker of black before the video plays. Better than showing the last frame of the video though in my opinion, but I know I'll have to figure out how to get rid of it eventually.

    Yeah right now we do not have sound on any videos; since our Rise signage currently is either silent ad slideshows in crowded places or silent menuboards that change at certain times.

    I'll try putting two mp4s exported this way back to back and see if there is no black flicker between the two on the display. In preview mode it flickers though.
    I'll also convert *these* to webms and see what those do.

    I take it back - now the two new mp4s i've created are showing "file is downloading" like before. This is so frustrating..

    1. If you could copy the entire presentation's HTML code to a text file (notepad preferably) and send it over to me prodo.us@mail.com. I want to see if there is anything in the presentation that might be affecting the video playback.

    2. You may also try updating Intel's video drivers: https://downloadcenter.intel.com/download/24971/Intel-HD-Graphics-Driver-for-Windows-7-8-64-bit (64bit version!)

    Sarah,

    This will be a short flash for any video files as they load the video, however it is typically extremely quick. Which Presentation are you seeing it with? I can jump into your Company and take a look to see if it is something obvious.

    Or, if you have already gotten that info to Darius, he is great at stuff like this, and will alert us when he has discovered the reason :)

    Thanks!

    Morning guys!

    Yeah the flash was manageable before, but now most of the time it flashes the last frame of the video before playing it and it's super ridiculous.

    It's doing this in both fsa-sign-TUNNEL and Fargo Sign 2, but Fargo Sign 2 is, like I said, the only presentation we have on the old editor since we share the display with the display owners. If fsa-sign-fargo was up, I'm sure it would do the same there as well, but my boss is currently working on the network for that display.

    Also I'm having weird luck with some videos even displaying right now...little to no mp4s are even showing up on the displays anymore, and sometimes the webms I put up aren't working either. They show a white screen and "File is downloading." And I do everything in the video file recommendations information, so I'm not sure what's going on. For instance, the Putnams video and Harriman video in Fargo Sign 2 are all mp4s, that play fine on that display, but when I put them on fsa-sign-TUNNEL they did the white screen "File is downloading" error. Also when I converted them to webms. The Campus Tees Spring 2016 video in Fargo Sign 2 is a webm, and for some reason did the same error on fsa-sign-TUNNEL. All the other videos are webms and do the flicker of the last frame before playing them. I've since removed the troublesome "file is downloading" videos off fsa-sign-TUNNEL besides when I was testing to see if they worked.

    fsa-sign-TUNNEL was *just* deployed in the last week, so the drivers are up to date.

    Text file of the current HTML for fsa-sign-TUNNEL is here: https://buffalo.box.com/s/4pl5k7tib33hvi4aw5odqgkl98dfs39n (I will delete this later for security sake)

    I won't update/test anything new until you have taken a look.

    Thanks Sarah, I was able to get that HTML and run the test. I must say I did not really realize what was going on until I ran your presentation here. Indeed there is a problem here and it is PUD setting! We have a busy selection of various images and videos at random time intervals. All of the videos have PUD set for them. The problem is that PUD makes videos to show the very last frame before starting the video playback. This is clearly an issue with that PUD. So yeah... RV needs to take a look at it.

    Now to the workaround!... my favorite )))

    #1. Replace PUD with the specific time for each video you need to play (video time -1s)

    #2. Add 'Fade' transition effect to reduce that nasty flickering before each video and it makes the entire playback appear smooth (without nasty cut-offs).

    I hope that helps.

    Also, try 'Fade' transition with PUD. That might help with that 'last frame' issue. I did test this idea.

    Update: I just did and I do not know... it sort of works, but not really... I am not happy with it, but it might be good enough for you. I do not know.

    Darius and Sarah,

    Thanks for helping us find this! I've logged a bug for this, and you can follow it here. I'll update this conversation when this is corrected.

    Thanks again!

    I think the current video in that log doesn't play enough to show the issue though but thank you!!

    Hello Sarah!

    I wanted to let you know that this issue has been corrected, and it looks great over here when I use my copy of your Presentation. 

    Can you let me know how it looks for you?

    Thanks!

    Hello!

    Seems like it was only fixed on Fargo Sign 2, which is the only presentation we have in the classic editor, since that sign's not under our control and it was the other organization's request to keep it in that editor. It flashes black real quick before playing but we'd much rather have that than a flicker of the last frame.

    For fsa-sign-TUNNEL, the flicker of the last frame still occurs. I took all videos off fsa-sign-FARGO a couple weeks ago because of this issue, but tested to see if the same happens on there real quick just now, and it does. Both of fsa-sign-TUNNEL and fsa-sign-FARGO use the current editor. Since fsa-sign-FARGO has been having the most white screen issues, I figure not giving it too much to handle is the best right now, so I removed the test video right after testing.

    Hello Sarah!

    We actually found issues with the update, and rolled it back yesterday, so it is back to what it was originally, sorry about not getting that into here sooner! That black flash, and other video issues that were being reported were the reason that we rolled back.

    I'll let you know once this is rolled out FOR GOOD!

    Thanks!
