Solved How to batch-edit those pics to create a slideshow?

[yetanotherlogin]

Hello,

On a recent trip, I took pictures with my smartphone and my camera, and now need to batch-edit them so I can create a slideshow as an MP4 video.

Pictures taken with the smartphone:
Horizontal : 4000 x 2250 Pixels (9.00 MPixels) (16:9)
Vertical : 2250 x 4000 Pixels (9.00 MPixels) (9:16)

Pictures taken with the
Horizontal : 1600 x 1200 Pixels (1.92 MPixels) (4:3)
Vertical : 1200 x 1600 Pixels (1.92 MPixels) (3:4)

How should I batch-edit the files so they look the same after I shrank them to 1024px horizontally?

Thank you.

Edit: It looks like I should add a black border at the top+bottom of 16:9 pictures taken by the smartphone, so that I end up with the 1024*768 I get from shrinking 4:3 pics from the camera.

I found no option in the Batch Modify dialog to add a background to 16:9 pics to fill the extra 192 (96*2) pixels need to get to 768.

Does IrfanView provide a way?

Try these settings (I have not tested it) and set your canvas size to 1024 x 768 with the desired background canvas colour (grey?)

Bingo! Thank you very much.

Out of curiosity, how do you highlight pictures like you did?

I use FastStone Capture as it is more powerful than IrfanView, captures images without loading IrfanView, and also records video. The free version 5.3 is adequate for most users. In IrfanView one can highlight the selected area using Image Effects, Colour Temperature, Sepia, and/or 3D Button.
