Great to hear you are making a go of PS for iPad.
I have a tip that may help you in timing your videos (or maybe it will help someone else)
Since the audio is always in overwrite mode (that is, it stays where you put it and doesn't ripple or move), and the video is always in insert mode (that is, it will ripple down when you put a clip before another), the easiest way to get timing right is this:
- Start by timing your audio tracks out: sync video, music, voice over, or whatever you need in your finished project
- Tip: Use the black clip found at the top of the video library, as a place holder for the video track whenever you need to drop a sync video clip after some other piece of audio and you haven't yet filled the video in.
- When your audio track is good, use the split tool to split up the black place holders where you think you want new clips to be, then drop your final clips right on top of the black clip(s) on the Storyboard. From the pop-up menu choose "Replace: Keep Length"
- Tip: you can pre-trim your clip's in-point in the source viewer, then drag your clip from the viewer to the black clip.
- After you have your final photo and video clips in place, use the Precision Trimmer to adjust cut points. To do this, tap on the trim handle of your clip, this opens the Precision Trimmer with your two adjacent clips in either viewer. MAKE SURE you tap on the link symbol between the viewers. This allows you to slip the cut in either direction (as long as you have extra media available on both clips) without changing your sync. (take away 1 frame from one clip and add it to another).
- If you want to adjust the in and out of a single clip on your timeline without adjusting sync, you can open the speed control tool on the clip (DONT change the speed), just move your finger left and right on the filmstrip to "Roll trim" adjusting the head and tail frame of the clip simultaneously. Keep in mind, you have to have extra media on the clip in order to use roll trim.
This is just one way to work (not the only way) but whatever workflows you use, I hope you enjoy the app!
