G3YQC - John
It is done by sending the transport stream from the PC to the Portsdown over the network. This Wiki page has all the details: https://wiki.batc.org.uk/Feeding_Video_ ... _from_vMix.
The only thing that needs adding is that if you are using a touchscreen, you should select IPTS IN from the "Encoder" menu.
Haven't tried it recently, but it should work.
The Portsdown is working fine and sends the built-in test pics, as well as inputs from my camcorder – via an EasyCap capture device – without problems so, suspecting that the BATC Wiki info may be out of date for the 2019 version, I need to communicate with someone who is successfully using the 2019 Portsdown with latest software and the current version of vMix.
I have been using both the original Batch file and the later H264 version from the Wiki. With both, using 1000kS, the signal sometimes locks initially then cuts out and tries to lock again…etc. Using 333kS is much better although the pictures often start to appear (top quarter) but then they freeze and get blocky and very jerky.
Anyone able to help please?
No error messages in the batch file window

I always seem to have problems ffmpeg !
I have tried 320-240 resolution for ext. O/P but no difference but I will try 384-288, just to see.
G4WIM - you have illustrated the problem exactly, in fact your pic is a bit better than mine. I have found that by using vMix colour bars as an input they mostly come out right! is this a pointer to a difference it outputting colour bars rather that a picture, either video or photo?
I am quite new to digital TV although I have been an ATVer since the seventies. Can I go back to analogue please? Hi
I have a script from Evariste It is a little old but should work when approprately edited. Not you need ffmppeg installed on your PC in C:\ffmpeg\bin\
Right, soldier on then, I will crack it (eventually)
