You're on the right track, setting the Still Frame Duration. Though do note that this setting only affects photos added to your Project Media AFTER you set the setting.
That said, what operating system are you using? What operating system do you have and with how much RAM?
In my books I recommend resizing your photos to no larger than 2500x1875 pixels in size (72 ppi). Oversized photos can choke the program -- particularly if you're adding over 100 at once.
I use Windows 10 with 8 GB ram. Yes. I set Still Frame Duration first before creating my time lapse project. The error message said "This type of file is not supported, or the required codec is not installed." What that means? Where I can set up image sequence? I notice that the saved project is a prel file, not psd file. Is it correct? Anything I miss in the Project Settings?
Thank you for your head up. Wonder if you have answers to my questions.
Hi Steve, to my first part of question: Can you make time lapses in Premiere Elements 14, what is your answer?
I'm not Steve. The answer is, yes you can. The question is what may be "wrong" with your JPEG files. Can you import one?
Hi whsprague, The issue was solved. I guess the change of Default Duration to 1 frame helps. then insert photos into timeline, render and make time remapping. Thank you for the help.
Hi Steve, Thank you for your comments.
Please mark this question as correctly answered, acanoe.
