Hi, good morning! One question: It is possible, to loud a diashow (lightroom 5) to youtube? Thanks for your help!
You can upload the exported Slideshow video to YouTube
Here is how you can create a slideshow video Lightroom 5: Publish a Slideshow - YouTube
There is no option from Lightroom to directly upload the exported Slideshow Video to YouTube
You can simply export the video and then upload it to YouTube
