I am a total beginner to video. I don't even know what kind of camera I'll be using. (I'll have to borrow one.) I am just looking for an overview of what the general process will look like.
I have an audio track of a song I wrote. I want to make a 'music video' of myself turning over pages on which the lyrics are handwritten. So as the song plays, you would see me flipping over the pages. But I'd like to include 'cut-ins' from different video files. For example, at one point the song talks about walking, and I'd like to create an effect of footsteps appearing on the page in real time. So each 'frame' would have a new footstep. Hopefully that makes sense. Along with a few more 'cut' effects of that kind, which it seems to me would require splicing together different bits of video and getting the timing right.
So my specific questions are:
1) What's the best software to use for a project like this? Preferably free and able to operate on a Windows 10 laptop. I have Adobe Premiere Elements. The learning curve seems high, but so be it.
2) What's the general procedure for making sure that my audio and my video sync up correctly? I will be working with an existing file, so obviously I can't sync by creating the audio and the video simultaneously. I have to sync them after the fact. Is there a tried-and-true method for making this happen in my situation?
