What version of Premiere Elements are you using and what computer operating system is it running?
What are the pixel dimensions of the Timeline photos that are going into this Time Lapse video and how many?
Please review the following, fill in your specifics, and then we can decide what next.
Thanks ATR - I just purchased and downloaded Adobe Premiere Elements 12. I am running it on a Lenovo Laptop, i7, 12GB of RAM, the photos are cropped to 1920x1080. I have 50 photos in one project, and 700 in another. When I drag-to-select all photos, or "cntr-a" or "select-all" the "time stretch" feature is zeroed out ... 00;00;00;00 ... and I can't click on it. I re-opened a new project and it worked there, but in the first project I tried it would let me select 5-10 photos to re-time, but not all!!
Thanks for the reply.
My first impression is that, when the Time Stretch is not working for you, the reason is that you have somehow gotten a video file caught up in the series of Time Lapse photos on the Timeline. So, first please check all the files going into the Timeline content to be sure there are no video files included.
Are you finding that the problem is occurring related to
a. number of photos in the TimeLapse
b. project to project
I did not completely understand that part of your report.
But, the symptoms that you report are pointing to a video or videos in that group of photos. Let us see.
Thanks. Looking forward to your results.
In the first project I attempted, the "timestretch" was not working well, and I didn't have any video clips in there (all photos from my Nikon D700, which doesn't shoot video!) - in the 2nd project, it worked fine ... thanks for your quick feedback and prompting questions ... if I have the problem again, I'll try and be more specific!
Thanks for the update with the great news that your second project worked fine.
I hope that the first project problem does not happen again. But, if it does, expand the Timeline with the zoom in and zoom out slider above the Timeline and inspect the Timeline content for irregularities (including a video file that may have crept in there somehow).
Congratulations on your successful Time Lapse video using Premiere Elements.
