Video export doesn't work

[dariop3390064]

I try to export video (only landscape foto) but after 10% completion it stops and does not end the process, without any warning (I tried to wait for two hours).Also 480*270 doesn't work!.  I am using last version of  classic CC 7.1 on IMAC High Sierra 10.13.2

Where did the video come from: What camera? What's the file format (.???)? How did you Import it (Add | Move | Copy)? What did you do to the video in Lr? Where are you trying to Export TO?

The more info you provide the more likely a solution!

It’s not a video, but  slide show that I want to export to be  used with other pc

[Neox99]

How many fotos? What is their format (file extension)? Are they all of the same file extension?

Does the slideshow work in Preview and/or Play mode in Lr?

first time there  was 32 photos raw and jpg, then I tried with only 2 raw photos but it didn’t work again.  it work perfectly in preview or play mode. If I save as pdf it’s ok.

Reboot your entire machine. This can be caused by a hung Adobe process that is used to index video.

I did it but the problem still remain

Try resetting Lightroom's preferences: https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/

Hmm,

I just tried exporting video myself and it also hung! Seems that this is just broken again. Seems others have this problem too: Lightroom Classic Slideshow Export Hangs | Photoshop Family Customer Community

Add your voice to that thread as Adobe engineers actually read that forum. This is a user-to-user forum.

Just close your LR, open again and click on Export Video! Simple like that!https://www.youtube.com/watch?v=XxzLOPMmX14
