Fix Mercury Transmit freezes.
Every so often the mercury transmit output freezes and you have to swtich comps to make it come back to life again. This happens regardless of whether the output is via GPU or third party card, in my case a Blackmagic Intensity Pro 4k. I questioned this via online support about 6 months ago and was told that Adobe were having 'some issues' with nVidia drivers. 6 months later and a new version of AE and still no fix. Can you please just get around to fixing the basics of the software before adding new pointless features?
This is still an issue 2 years later... Get around to fixing it will you, Adobe?
Still an issue. Bit of a joke, Adobe. This has been an issue for two years now.

Yes Mercury Transmit freeze (or stay black) randomly very often for no reason (v17.0) whereas the main viewer still work ok.
I am on Windows 10 with nvidia GC, same thing with Blackmagic video card.
One year on and still no fix. What have you guys been doing all year?

I do have excact the same issue on two different machines: an HP Z840 with Geforce GTX 1070 Ti (419.35 driver) and mercury transmit (now called MT) output on a BlackMagic Decklink 4K Extreme card. And an HP Elitebook 8760w with an Geforce GTX 980M card (419.xx driver) with the MT output set to the second display output of the laptop. I work with European framerates (50i or 50p). On very random moments the mercury transmit output freezes while the composition panel just works fine (even during rendering of a ram preview for excample). I mostly have Premiere Pro (now called PP) running in the background (pre-edit is dynamic linked to AE). Switching to PP (when AE MT freezed once again) gives the MT output of PP correctly, but switching back to AE won't let AE MT take over. I still see PP MT output. As randomly the MT preview of AE stops, just as random it can come back and correctly update the preview for a while. Creating a new composition in the same AE project, but with another resolution does indeed 'fix' it, the MT output now switches the BM decklink card to the corresponding resolution. And when I then open the comp where I already worked in, it switches correctly back and gives me the correct frame on my external monitor. Again for a while. I hope this information is helpful in finding the issue that is causing this.
