The video is going to have the same aspect ratio as my landscape photos, so they are not treated in a special way. Putting both into the same video means that one of both types needs to be treated in a special way. That last bit is important because in a large set of photos we usually find two different aspect ratios: we shoot most photos in landscape orientation, but others in portrait orientation.

The video filter syntax (the part after -filter:v) instructs ffmpeg to output a video with 2560 pixels width and 1440 pixels height, retaining the aspect ratio of the input image files. Ffmpeg.exe -f image2 -framerate 8 -i resized_renamed_2560/resized_%05d.jpg \
