Hello everyone. I'm Pablo I'm a new user in this comunity.
I' ve ben searching in this forum and in the newteck forum as well, but I can't find the answer or anny suggestions.
I work in a TV studio (recording shows in live situations) and i'm currently using Vmix as a playout system (I know! vMix is not a playout, but it works for me), via NDI to a Tricaster 460.
Set Up:
Intel® Desktop Board DX58SO
Intel I7 3.05 Ghz
8gb RAM
Nvidia Quadro K2000
1 SSD for the system and apps
1 RAID 0 for the Data
1Gb ethernet port
1Gb LAN (14-15 pc aprox)
Don't know the switch or the router specifications, sorry.
It's working very well. I can send several sources to vMix (premiere, vlc, videos, ppt, etc.) and send the vMix Output to a NET input in the Tricaster without having to change the source in the Tricaster every time. Besides, I can send the sources directly to Trciaster, play two or more videos simultaneously at 1080 50i with an excelent quality.
The problem appears when sending a video over NDI, another user of the LAN starts transferring files from one PC to another. Video starts to fail (frames and audio drops, in a terrible way) In other words: every works fine until the bandwith is share.
The question is: Is it normal? Is there any way to control the bandwith to give priority to the NDI when it Is necesary?
By the way, sorry for my pour english
Greetings from Argentina!
Pablo

Hi Pablo, welcome we had the same question at some point The reason is a file transfer takes up all available bandwidth, kind of selfish if you ask me There is a way to throttle file transfer apparently by using robocopy.exe which is part of windows Havent tested it yet myself though there seems to be some utility to also calculate a robocopy setting http://www.zeda.nl/index.php/en/robocopyipgcalculator-en-2
