P:Need a check box in Slideshow that automatically resizes the images to fit the screen in Play mode

In Slideshow, the image in the Template Preview correctly zooms to Fit, but when you Play the slideshow, or export the video, the image reflecst the original image size.  The only way to fix this is to open each image in PhotoShop, manually change the image size, and then resave the image back into Lightroom.  This is extremely tedious and timeconsuming when you have 100's of images in a slideshow.  A much better approach would be to have a "Check Box" in the Layout section that will automatically resize/zoom the image to Fit the screen in Play mode.

My experience is that large pixel size images will down-size to 'fit' the slide-show screen, but small pixel size images will not up-size (re-sample larger) to fit.

[Zoom to Fill Frame] does NOT with 'small' images!  This is the "Check Box" that should zoom to fit! IMO

Your workaround with Photoshop to up-size is not needed- the same work-around can be done entirely in Lr-Classic, in ONE batch Export.

Select all the images for the slide-show and Export them with a Resize (uncheck 'Dont enlarge') with dimensions to fit the intended slideshow video format. Use the 'exported' files for the slideshow.

If your only intention is to create the video-slideshow, then the exported images can be deleted later.

Rob, thank you for this option.  Is there a way in LR to maintain the image ratio when resizing?  For instance, in PS I was able to set the Height and PS automatically reset the Width based upon the original ratio of Height to Width.  I did not see the same functionality in LR.  This is important since many of my images are of different H to W sizes. 

I also found that slideshow will down-size, so I make the image height slighly larger than needed and it down-sizes properly to fit.

All 'Resizing' functions in Lightroom will not 'resize' to a specific ratio- That is a job for the Crop Tool- before you export.

The Resize in the Export dialog will only re-size images to 'fit' within the boundary of the Dimensions stated in the Export dialog.

So if you want all your images to 'FILL' a screen 1920 x 1080px, then you could-

1)  Create a new Collection with all your SS images. Hint: Create the Collection with VIRTUAL COPIES!

2)  Crop all the Collection VC images to the 'Ratio' required (16:9 for 1920x1080px). Do one-by-one where YOU check the crop, or [Auto-Sync] and let LrC crop all to 16:9. **Then preview each Collection image to check the crops were suitable to YOU. (Using VCs prevents you affecting your 'original' files!)

3) Export the Collection images with the 'Resize' dimensions required in the Export dialog. (eg. w1920 x h1080) and Check to Include in the Catalog! (so then you do not need to import the exports.)

4) Use the Exported files in the SS.

{ 5) Delete the VCs and Collection later if not needed again. }

It all sounds complicated but in reality, once you understand the method, you will realize it is relatively simple. A Collection of VCs is 'easy'. A batch crop is 'easy'. An Export using a Preset is 'easy'. Selection for the Slideshow module is 'very easy'. 🙂

Thanks Rob.  Would be a lot easier if there was a "Check Box" that would automatically zoom to Fit in Slideshow! 🙂

Agree!

There is a checkbox to Zoom Fill- but it doesn't with small pixel sized images.

Be good IF it worked!
