Reduce them in size.
Believe it or not, the photo will actually look better the closer it is to video resolution.
A good size for a photo in a video project is 2000x1500 pixels (at 72 ppi). Photoshop and Photoshop Elements include a batch processing tool that will resize an entire folder of photos with just a couple of clicks.
What version of Premiere Elements and what computer operating system?
By any chance are you using Premiere Elements 9.0/9.0.1 or any version that is on a 32 bit computer operating system?
Are you getting a too large message when you go to import your photos in the Premiere Elements project?
and yes, I get a too large message.
Computer operating system i don´t know.
Thanks for the reply. With Premiere Element 9.0/9.0.1, it is a 32 bit application running on a 32 bit computer or 64 bit computer. Premiere Elements 32 bit application has that too large blocking message, a Premiere Elements 64 bit application does not. With Premiere Elements 64 bit, you can import jpegs as large as 10000 x 7500 pixels and not be blocked by the program from importing them. That does not mean that because you can that you should. The answer will depend on your computer resources. In the end, the pixels dimensions will be those of the export settings.
Premiere Elements Windows becomes a 64 bit application with this perk when you have Premiere Elements 10, 11, 12/12.1, 13/13.1, or 14 installed specifically on Windows 7, 8, 8.1, or 10 64 bit.
I addressed the Premiere Elements 32 bit application in this type of issue in post 6 of the following
Consequently I contribute this information to include with your decision - resize images to the total pixel count limit for the 32 bit application or consider the opportunities in Premiere Elements as a 64 bit application.
Any questions or need clarification, please do not hesitate to ask.
