  1. Hi Hugo, I've just sent you an email about this. Best regards, Rainer
  2. WATCHPAX 4 has framelocked outputs and can drive 4 LED controllers. Having said this, I would not suggest using it for this scenario for two reasons: 1) WP4 can play 4x 4K with 30fps encoded as HAP but for more data throughput the internal raid is too slow. It will just deliver some 1GB/s max. or less. Running those files with internal looping or fading into 4 new videos somewhere might hit the border. 2) WP4 can not use cross-server sync since it does not have a sync board inside which would deliver a signal to the next graphic card.
  3. Most codecs use the cpu for rendering (in WATCHOUT systems), except for h264 when using WATCHPAX servers with enabled hardware acceleration and for HAP which also uses the gpu. For large files and when you use many outputs with high resolutions from one server the memory size of the gpu can be an issue. I doubt though that any card with 6 outputs can really give you 6 output screens with 4K and 50/60fps. The gpu might be fast enough but there are plenty of bottlenecks in the processing chain of a server. Be aware that AMD graphic cards do not support more than three 4K outputs under Win7 due to a driver issue!
  4. You will definitely have to pre-split the content to make it playable. How much you have to split depends on the codec, the frame rate of the video material and the performance of your WO servers. Splitting the content helps a lot to level out the load on each cpu core. For HAP the same can be achieved by using chunks, but you'll still have to reduce the number of pixels per stream. I would maybe go for two or three servers with 4 outputs each and use the outputs in portrait mode, i.e. each 4k output would play a file with 2160x3465px. Make sure to use a sync board to framelock/genlock the outputs. DO NOT render any transparent (empty) parts, e.g. do not render slices with 2160x3840 (because this is the UHD resolution) but render it to 2160x3465px as this is representing the real content size if using vertical outputs.

    HAP playback

    It's always wise to not change things in an uncontrolled way, but MPEG2 is rendered using a WATCHOUT direct draw filter. The same goes for other supported codecs. That's why you do not need to have QT installed on display computers anymore. Regarding the license key, if you own a WATCHOUT 6 license key, you will be able to use this with all versions 6.x.x. The latest version is 6.3.1 right now and there have been quite a few bug fixes in the early versions of V6 as well as some new features on the way. https://www.dataton.com/watchout-release-notes

    Stage view preset

    Hmmm.... It's not really possible to change this through the timeline but what could help is to use different TIERS for the different screens. There is a setting in WATCHOUT to frame the displays and this will always frame all displays of the active tier and scale this up to the size of the stage window.

    Resolution issues

    It looks like an EDID problem to me. It is not advisable to copy the EDID from the display to the EDID manager directly since this will copy all resolutions and frequencies at the same time. The graphic card discusses the optimal resolution with the display and if all frequencies are available, they will agree on what they decide is best. Our approach is to use an EDID manager which can be set to a fixed resolution/frequency through dip switches, a dial selector or software. Then the graphic will only see the resolution/frequency we want to use and will switch to that.

    Watchout Flickering

    Are you sure that the DP adaptors are active??? Is it this model? https://www.mwave.com.au/product/ugreen-20401-displayport-to-hdmi-mf-converter-aluminum-ac07162 Does not state anything about "ACTIVE" and the price would rather indicate a passive adaptor.

    Choppy Playback on ShowServer XHD R4

    Hi, When looking at the specs of your computer, I have some questions about your SSD? Is it the EVO or the PRO version of the M.2 960? The PRO would be the one to choose here. Is Windows residing on the same SSD or on a separate SSD/HDD? I do not know which mainboard you're using, where does the SSD sit? Flat on the mainboard? Is there a good airflow around the SSD? Those M.2 SSDs tend to heat up a lot when they deliver video data. This even more if you use large and less compressed codecs. ProRes files are usually rather huge and the same goes for HAP-Q. Out of those I would rather go for HAP-Q and not for ProRes. ProRes is a codec designed for post-production and not really meant for playback. You could also try H264/MP4 if encoded following the guidelines found in various threads in this forum. When the SSD heats up it will start to throttle, means it's performance will go down. We have some servers using the 960 PRO M.2 SSD but we are now using PCIe slot carriers with a big passive heat sink and we have an extra cooler (vent) blowing air onto it. Since then we did not see overheating anymore. Benoit's hint of cutting the large video into smaller portions might help. In fact it is not really the same when it comes to performance whether you use a 4K video or 4x fullHD files. Using 4 files will help since then it would make use of more cores instead of squeezing the whole video through one core. Of course, using chunks does the same in a way, but this only works with HAP codecs. Hope it helps Rainer

    Windows 10 Tweaking Guide

    Hi Misterk, We have built a couple of servers using 1607 Enterprise LTSB and the update KB4057142. We did some additional changes in the group policies and scheduling but basically if you follow the tweaking guide you should be fine. I doubt that anyone in Sweden can tell you right now whether the updates from 11/13/2018 are working. Looking at the date, they are 24 hours old now. To make sure that an update works well under all circumstances you will need to build a master image first and then have a couple of people testing the system over a lengthy period of time. All recent WATCHOUT servers are using the master build based on version 1607 and it makes no sense for Dataton to have various operating software versions in the same sort of products.
  11. NvTmMon, NvTmRep and NvTmRepOnLogon are not needed. They only spy on your computer. The other Nvidea items should also not be neccessary. Also I would not install all those Nvidea drivers, except if you use the 3D capability or want to do gaming. On my computer I only have the graphic and audio drivers installed. Apple software update has caused issues on some computers built by my clients in the past.

    Windows 10 Tweaking Guide

    Search will not work if you turn it off in SERVICES as described in chapter 11. Drag and drop should work.

    WATCHPAX autostart up

    Create your show with your production software and go online. Test that it works from your production computer. To make things easier use a cluster name and a computer name instead of an IP address. Click onto the header of your stage window, then into one of your screen rectangles and then use the "Remote Access" coomand thorugh your menu or by sending the keys Ctrl+Shift+A Your display computer should now show a smaller screen with a menu bar. Go to File>Edit Startup Script and edit the auto start script. All lines starting with ";" are comments only. Search for the block ; authenticate 1 ; setLogoString "The show will begin shortly" ; delay 5000 ; load "MyShow" ; wait ; run and delete all ";". Then swap "MyShow" with the name of your project without the ending ".watch". Watchout is case sensitive! Save the file and restart the WATCHPAX without the production computer being online. It should now start WATCHOUT, show the cluster name, computer name and the text "The show will begin shortly" and should then load your show and run the main timeline. If you use auxiliary timelines, you will need to use run "name of your timeline" instead of just run. All described on pages 159 and 173 in the manual.
  14. Have you checked your startup items (run shell:startup) to see whether there are any other things which run in the background stealing the focus? While tweaking a win 10 computer I also noticed that the Nvidea card installed a couple of scheduled tasks to run daily. I deleted those of course but I'm not sure whether your consumer card also has tracking or auto-update components which might be triggered once a day.

    4k Capture Card Sdi or Dvi/hdmi

    The output resolution has nothing to do with the capture card resolution. Selecting a capture card depends a bit on what sort of signals/players you plan to use, sending their output into the WATCHOUT system. If you use computers as sources and maybe semi-professional camera systems, a capture card with HDMI 2.0 should be fine. DVI does not support 4K! There are also capture cards supporting DisplayPort which also goes up to 4K. I have not seen many professional camera systems with 4K on SDI in the event and staging sector. This is due to the very high costs of professional 4K cameras, mixers, class-A monitors etc. So people tend to stay with what they have invested in for longer times. Also [email protected]/60fps is not (yet) a standard for TV due to bandwidth and infrastructure.
