Playground Posted January 17, 2020 Report Share Posted January 17, 2020 I recently had to bring in a keynote presentation into a Watchout show. Using NDI scan converter for mac the NDI stream was not frame accurate. We are presenting on a large LED wall so we had to use a 4K keynote for pixel accuracy. This is essentially a road show so I need a better solution. Would you use a 4K HDMI to NDI capture box or Would you use a 4K HDMI to Usb capture card? Installing 4K capture in our servers is currently not an option. Magewell $K usb capture is a thought but I am intrigued by NDI The presentation in Keynote is critical and a switcher is not inline between Watchout and the LED processors. Any thoughts are welcome 0 Quote Link to comment Share on other sites More sharing options...
wiesemann Posted January 19, 2020 Report Share Posted January 19, 2020 Hi, This is coming up a lot this week. I recommend trying vMix instead of Newtek Scan Converter. I would not expect frame accuracy form NDI. 0 Quote Link to comment Share on other sites More sharing options...
Dataton Partner RBeddig Posted January 20, 2020 Dataton Partner Report Share Posted January 20, 2020 Are you using one server for the LED? Which graphic card? Are you using a sync board? Is it NDI or NDI/HX you're talking about? 0 Quote Link to comment Share on other sites More sharing options...
Playground Posted January 24, 2020 Author Report Share Posted January 24, 2020 We are using 2 servers for the wall but in a main and back up scenario. They have sync cards in them but are only syncing their own outputs rather than daisy chaining. We are using NDI scanconverter not NDI /HX (not mac compliant). It turns out Scan converter will not give you frame rate accurate outputs the dropping frames just gets amplified by the size of the wall The entire network is gigabit though not a mangaed switch All Cat6 cables We did testing with powerpoint later this week and were equally disapointed with the results. While the whole Video over IP thing is a really good idea there seems to be too many competing Technologies. NewTek need to improve scanconverter Thats my 2 cents Ben 0 Quote Link to comment Share on other sites More sharing options...
