Really struggling to synch up two videos to the same handclap marker in the audio. (does that make sense)..........The more I zoom into it the less control I have over where the marker goes. It jumps to either side of the start of the clap but wont let me slide it to the beginning of the audio wave !!! (does any of that make sense....)
What version of Premiere Elements are you using and on what computer operating system is it running?
Assuming some version of Premiere Elements on some version of Windows....
When you are doing the alignments, are you using the technique...
Expanded Timeline (via -+ slider above Timeline) should help, not be counterproductive here....
a. Hold down the Alt key of the computer main keyboard and tap the right or left arrow key (1 tap = 1 frame nudge)
b. Hold down the Shift+Alt keys of the computer main keyboard and tap the right or left arrow key (1 tap = 5 frames nudge).
Please supply more details so that we can fine tune a reply to your question.
