What photo format , Jpeg, Tiff, etc should I use after editing it in Photoshop Elements to use it in a video in Premeire Elements 11? I just used a photograph formated in Jpeg 5 and used it in a video I made with Premeire Elements and it isn't as sharp as the original. Do I need to change the photo format?
The photo format won't make much difference. But you should rez down your photo's resolution to more like 2000x1500.
But also remember that video is video resolution. It's never going to look as clear or as detailed as a photo.
