Can't export slideshow to movie.

Tryed to make a 99 pic slide show for my grandmother funeral service now I cant use it at all because after trying all the suggestions on this page I still have no success someone please fix this so I can actually use the program.

I am having this same issue. I have spent over 8 hours on a 3 minute slideshow. I am so irritated at this point. COME ON ADOBE!!!

The procedure that worked a few days ago does not work today. I now have no idea what procedure will allow me to export a Slideshow as a movie.

All I know is that, if I am able to export a slideshow once, I do not seem to be able to export it again without restarting my computer. However, restarting my computer does not guarantee I'll be able to export a Slideshow as a movie.

Arrrrg!

Well - the above procedure only seems to work sometimes. It does work after
- restarting my computer
- moving a photo around in the slideshow, then back
- export video

However, if I try to change some more slide titles, and export again without exiting from Lightroom or restarting the computer, the export does not start.

I have found a workaround (after trying a bunch of things that did not work) that seems to work at the moment... If I:

- select my Collection on the left in grid view

- move the location of a photo in the collection (drag it one to the right)

- move that photo back to its proper spot

- click Export Video

Now the export starts up, and the progress bar at the upper left displays progress being made.

Oh - by the way - I am using the Desktop version of Lightroom 6.8, NOT the Creative Cloud version.

I can export a PDF just fine, but exporting a video displays the progress bar at the top left and then freezes there... no progress is shown 20 minutes later, and Task Manager shows Lightroom using no CPU time.

The times that exporting a video worked for me, I instantly saw some progress on the progress bar as soon as it was displayed. When it is not working, no progress is shown at all.

I have the same problem on a Windows 10 (AU) PC. This happened the first time I tried exporting a movie, but then everything worked fine the 2nd and 3rd times I tried. Now I cannot get the export to make any progress at all again.  I am exporting an 80 slide collection to a 720p movie accompanied by an MP3 file that is exactly the right length.

I have tried exiting and restarting Lightroom, restarting the PC, etc.
