Not knowing better, I tried my first PrE slide show project with huge RAW stills. It worked without crashing or stalling.
For a year I've been learning and practiceing with Lightroom and like it a lot. It has a very convient risizing tool.
I'm confused on a setting. Bill Hunt used Photoshop in the article linked by John Smith. It does not mention "pixels per inch". Also, I'm setting the "long edge" at 1.5 x the original's 1920 to make room for Pan and Zoom.
I don't know what to do with "pixel per inch" to match or optimize for a AVCHD 1080p project. I'm guessing at 140.
Screen shot of Lightroom export page:
Do these setting look like they make sense? Should the pixels per inch be different?
I googled "hd video dpi". There were various posts in various places that said "dpi" and "ppi" were confused and didn't really apply to video. But, 72 ppi is assumed by some to be the appropriate standard.
There was not consistant agreement!
I posted the same question in the Lightroom forum and got the answer that "ppi" settings are meaningless here.
While I was at it I tried several things. One was to use dimensions greater than 1920x1080 to improve Pan&Zoom. I could see no difference other than the files were bigger.
