I work in Hollywood as a camera operator, Steadicam operator, aerial photography operator (i am Part 107 certified FAA operator), and music producer. I have a publishing company through ASCAP and have been in this industry 30 years. This is how I qualify my posts here.
You can absolutely connect everything up as you say, no problem. You just need a TRRS adapter that will spilt the audio inputs/outputs. These are all over amazon if you are in the US.
You can also record solely on the zoom AND use the cheap mic on the phone to get wild audio. Sync them without the camera by just slapping your hands. That blip on the timeline in your editor will match up nicely.
I’m just saying that you are going to get the best audio quality just using the zoom. This is why pros use external recording gear.
Further, with what you are wanting to do, you will introduce some latency into the process and , depending on the apps and phones CPU cycles, this can show up as a frame (or more!) on the timeline, so if you are using the camera shooting high frame rates/resolution AND you want to capture high-quality audio, you are asking for some issues downstream.
You mentioned that if there is lag you can use reaper... i mean why even do all of that when you can just keep the process as simple as possible with less gear in the signal path?
Marc,
Thanks a million for your replies. And you're right. I respect that. Less gear in the path.
But wait! There's more! I was born in Hollywood (90028) into a family in The Industry. Dad was a singer/dancer (all the MGM Musicals, etc), Mom, Betty White, and another actress had almost ALL of the TV commercials in the late 50s and did some acting, Step-dad was the most respected stuntman in Hollywood and had a couple of very popular western series, Step sis is a working producer (or is she directing? I forget) for some popular TV shows/series, other step sis won some Grammys and an Oscar by acting, and I wasted those connections and ran away to the sticks near Seattle (after Hawai'i, etc.) - LOL. Besides that (name dropping) I kinda grew up on sound stages. That's what qualifies me to have a profound and deep respect for your feedback. I used to do about 40 consumer wedding vids/year in LA, have been a photographer (casually) for about 50+ years, and am now flirting with getting Part 107 cert and chasing that business in some small way - that and perhaps voice-over acting...
I'm currently an (alternative) primary care physician with about 3 decades of clinical experience and have a family that keeps begging me to sit in front of a camera and spill what I know on various important health issues. I really should just get a real camera and a shotgun mic.
Why do idiots like me keep trying to do things the cheap way instead of the right way? I probably spend more time trying to figure out a Note 8 + Zoom H5 combo than doing exactly what you mentioned: Use my organic, built-in "clappers", and sync the audio in Reaper. Loving high def and hating latency as I do, well, I don't want ANY video to look like foreign footage dubbed with English - lol.
I think you just talked me into getting a small video camera and doing it right because even the Note 8 skips a frame once in a while (when panning - depending on settings, etc.) even though I'm saving to the phone and not to the card.
Many thanks.
And may you have many f-16 days.
