Smaller images don't fill the screen in Slideshow

[Musoade]

Hi all!

For the first time I thought I'd try the Lightroom Slideshow tab to get an important job done quickly... simple yeah?

I tested it with full sized images from my library and all looked good - however I needed to use reduced size images sent to me by my fellow club members - and this gave me a big problem.  Despite clicking "Zoom to fill frame"  - it didn't!  All the images were displayed in a reduced frame despite the image appearing perfect when in the editing stage - as soon as I press play the images shrink!  And this isn't cured by saving as a video file - same deal...

If I replace the images with originals from my library all looks good - but all the other images were 1600x1200 max.

Anyone else have this problem?  In the end I used my video editing software (now Da Vinci - was Premiere pro (sorry)) - and this did the trick, eventually, but I really wanted to use the metadata from the images which a video editor doesn't expect to do.

Thanks!

TBMK it has always been that way in LrC SS- Small pixel size images do not expand to fill the screen.

One workaround might be to -

1) Select ALL the photos you want in the Slideshow (eg. a Collection).

2) Export them all with a 'Resize' to the pixel dimension you need (eg. 1920x1080px). (Add to Catalog, include metadata)

3) Create your SS from the exported files

You can always delete the exported files at a later date if they now serve no further purpose.

Note: That "Resize" sets the maximum pixel dimensions for the exported files- Small pixel images will be 'upscaled'. Large pixel images will be 'down-scaled' to fit. ie. All the exported images will be consistent in size (ie. Made to fit within the  size specified. eg.1920x1080px)

Great idea! 
what confuses me however, is that when I'm editing the parameters of the slideshow the images look fine - also they fill the screen when using the develop module - so there's clearly enough pixels to do that!  Pretty poor imho.  
thanks for the work around..

OK - furthermore - for those that are interested... to get the images to fill my screen (MacBook Pro 16" - retina 3456 x 2234)  I had to resize to 3200 x 2134 - seems that LR SS does a 1 for 1 pixel conversion (no conversion) - making things 1920x1080 left them the same size or smaller(!). Clearly when the SS is rendered as a video file this is when they get shrunk to HD dimensions... shame there's no 4K rendering g!

"shame there's no 4K rendering"- Yes, that's the limitations of the SS module-

Only options are-

For better you will need a dedicated Slideshow App.

Example:  'PTE AV Studio Pro'

@Musoade: "shame there's no 4K rendering"

The Any Video Preset plugin provides 2K and 4K presets for exporting video and slideshows. The export presets work on both Mac and Windows, but the slideshow presets only work on Mac due to LR limitations.

@Musoade,

There's a bug in LR causing the misbehavior you're seeing. When a slideshow is exported as video, the dimensions of all photos are cut in half. So if a photo's dimensions aren't at least twice that of the exported video, the photo won't fill the frame.  The workaround, as you've discovered, is to enlarge the photos, to at least twice the size of the video dimensions.   

See here for more details:

The bug usually isn't noticed because most photos are more than twice as large as the maximum video dimensions (1920 x 1080) supported by LR's built-in Slideshow presets.

Thanks - nice to know someone cares - even if Adobe don’t (apparently).
