Digitize Analog slide show with audio track, etc?
I'm a Photoshop pro with only rudimentary experience in Premiere Pro.
I am digitizing an analog slideshow with audio. The original presentation has slides and a sync'd audio track, which I captured as a live video template. I then captured digital stills of each slide, and made a separate audio recording of the original audio track (from tape).
Questions as follows:
1- I digitized the slides at 1920x1080, but mistakenly recorded the video template at 1280x720. Can I change the resolution of the project to 1920x1080, or do I need to start with a new 1920x1080 project?
2- I would like to have a short dissolve from still-to-still (like a traditional slideshow). Do I overlap them in the timeline and apply a dissolve transition to all, or is there a more efficient process?
Any other suggestions for creating this slideshow?
Thanks for any feedback.
