Are those the only choices you want to consider? Which do you already use? Here's my take on the slideshow capability in each:
- Photoshop CS6 and CC: You can create slieshows in a video format but you will have to crawl through hoops and climb barrels to get what you want. The timeline feature of Photoshop is not exactly intuitive.
- Elements: Can't comment since I have never used the software.
- Lightroom: much easier than Photoshop to create a slideshow but also extremely feature limited. Slideshows can run directly from the software or rendered as a video. Only one music track is allowed with limtied transitions effects. Want the fabled 'Ken Burns' effect? Forget it!
Neither of these choices specifically target slideshow creation and I would certainly not pick any for this purpose (unless you already use them). Best to seek software dedicated for slideshows. Several are free.
None of those. Microsoft Photo Story is quite nice for this type of work, surprisingly. Or even Movie Maker.
With PapaJohn's export profiles you can export HD if you need it.
You did not mention the OS you work on, though. MM and Photo Story will not work on a Mac. Use iMovie on a Mac.
I suppose Adobe Premiere could also be put to work for slide shows, but that's like driving a Formula 1 car on a dusty 50 miles per hour road. Overkill, and not exactly intuitive or fast.
First I've heard of Proshow Gold. Windows only unless you run a Windows virtual machine on a Mac.
I wonder why people would use it rather than Microsoft Powerpoint?
From what I've heard, it is a whole different animal with a timeline that you can mix video and stills and sync audio to. I've been organising all the AV presentations for the Convention we are running from tomorrow, and about 80% of them were made with Proshow.
One is quite impressive with compound movement on mutltiple paths and layers in apparent 3D space, and it was definitely done with Proshow. I thought it the best of the entries for this particular AV competition, but we are talking Photographic Society here, so it was the arty B&W presentation that won.
I use Premiere Pro and After Effects myself, but I bet Proshow is a lot easier to get to grips with.
