Part of the issue is that Add Frame Hold doesn't work as advertised. Try this:
- Drag an image sequence to the timeline
- Decide that you want to hold the first frame. So position the playhead at the beginning of the clip, right click, and choose "Add Frame Hold."
Expected: PPro should split the sequence into two pieces: the first piece should be the first frame of the sequence as a held frame that you can stretch across the timeline for as long as you want. The second piece is the rest of the sequence.
Actual: PPro obliterates the rest of the sequence and makes the entire thing show the first frame. So you have to click and drag the sequence in from a Bin a second time to get image 2 onward (and possibly resize/reposition the clip to match image 1). To my mind, it's a lot more straightforward to drag image 1 from the Bin, stretch it past the point where i need image 2, make a cut, and then alt-drag image 2 into the second clip so it inherits the position and scale of image 1. Repeat. (If i'm insane to do it this way, please let me know!)
With the style of video i produce, "held frames" are the rule, not the exception. It's more rare that i'll need to play a sequence of images at speed to show an animation, and much more common that i hold on an image and blather on about some board game rule for a sentence or two, before changing the image. If i were to use held frames on a sequence, i would constantly be zooming waaay in on the tiny, short sequence to hold frames, and then waaaay out to stretch them over my vo. Then zoom waaaay back in, hold a frame, then waaaaay back out. Sounds time consuming!
i'll check out Dragonframe and Stop Motion Convert - thanks for the tips! What i do is not 24 or 12 fps in the traditional sense... it's just sequential images held over a vo, with very occasional bursts of motion. i switched from a DSLR to my iPhone a few months ago. i just position the elements on my table, and then click to take a picture with my remote shutter button so that i don't have to touch the camera. i'm using the Pro Camera app for stills, and Filmic Pro for video, because i can manually set the white balance in each. (And Filmic Pro gives me a clean hud-free feed, so i can stream with it if i need to)
