Ok, thanks! I'll do.
This issue should be fixed in Photoshop CC 19.0.1. please open the creative cloud application & click on Update to install this patch for Photoshop.
because I can not build a simple slideshow on LR CC Classic, even re installed it many time, I gave up
so now I am trying to do the same on Photoshop and guest what, when I launch the rendering of the video, it's stopped at the middle
What is going on Guys ?
Photoshop is junk thats whats going on.. I can't believe I pay for this junk app the support that ADOBE offers is PATHETIC!
3 second clip I can't render !!! What a joke...
not helpful didn't fix issue
As per post 1, this is a known issue in the current version of Photoshop. Adobe staff are aware.
See this link for more detail:
If you need to export a PNG image sequence in the meantime, until the fix is issued, you can reload CC2017 (older versions can co-exist alongside the current version) and use that to render.
