Setting timeframe for individual photo-frames - in bulk

I’m having trouble making a short 30 second video out of 1000 JPG images, from my trail camera…
I’ve watched the youtube vid on how to use it, but, cannot seem to shrink the time-frame for each of the photos to 1/10th of a second…, and to make a video of the 1000 image files…
Is there a “Select All” feature, and to bulk time-frame all the images to 1/10th of a second?

Then…?

Thank You… Now all I have to do is save the project as an MP4…
