Saying “hear, hear” is silly in this context, but all the same: hear, hear.
My wife is working on a podcast for which I’m engineering much of the audio (the things our spouses rope us into, eh?), and I pushed them from the very beginning to get and post transcripts for precisely these reasons. It makes the editing process easier, it makes them more accessible, and it makes it so people like me, who can’t spend hours listening to podcasts every day, able to still access it.
Transcription is so easy and cheap these days. There is no excuse. -
If you WERE trying to get the piano to play itself, like Mark Suszko is suggesting, you could just go shoot a Yamaha Disklavier for half a day. They play back MIDI files in real time, on a real keyboard, just like a ghost playing it. https://usa.yamaha.com/products/musical_instruments/pianos/disklavier/index.html

The method that Mark is outlining is actually still 100% the best way to do this–and it will be easier than the other way around.
Now, caveat: I can’t see your footage, so there may be something preventing this, like black sleeves–those you might have to mask/roto. But hands over a black and white background ought to be easy!
All you do is add a Chroma Key effect, use the color picker to select the orange-y skin tones of the hand, and then play with the settings and range. Then, crucially: invert the effect. Normally it REMOVES all the color you select, like in greenscreen, but if you invert the effect: presto! Just hands.
You may get some artifacts from reflections on the black piano surface, but otherwise, I bet this is very doable. You will then have the challenge of any sleeves the performer might be wearing, and there’s probably no way except the rotobrush or fairly tedious masking to deal with them.

I’m not a Trapcode user, but from a purely conceptual standpoint, I think the emitter needs to be tracked to follow the motion of the person from which the bacteria are shedding, so that they have motion that follows the emitter when they are born. I’d bet that will create most of the motion you need for a short shot.

Not a Media Composer user, but chiming in to say: I would suggest a frame blending method over an optical flow-type solution; it looks a bit more like natural motion blur, and works better the faster you speed up the footage. Optical flow/morphing-type effects work better for stationary camera + moving subject; you get lots of artifacts when the camera is moving.

Weird possibilities abound in this business. When I was working for a small studio in Monterey, California, we kept getting this weird staticky interference on our powered studio monitors in one of our edit suites. I checked EVERYTHING. Power grounding, loose connections between audio interface, ferrite on the computer’s power cables, sound card, different output channels on the mixer, different sources, but it was always intermittent and I could never trace it. Then one day, the static resolved into the local radio station–the cables were coiled in such a way that they were acting as a perfect antenna, and the powered monitors were amplifying the signal. I switched to shielded cables.

One last thing–I found something suggesting that cell phone 4G signals sit just below the low end of channel 70, near the 863 range. https://www.soundservices.co.uk/wireless-microphones-radiomics-uk/ So maybe pushing the channel settings up to the top of the available settings, to the 865 range if possible, might help, too.
Listen to the noises produced here: https://www.apwpt.org/technical-papers/dr-h-b-karcher/lte-interference-to-wireless-headphones/index.php sounds like longer versions of what you posted, no?

I think the first thing to look at is whether there is some faulty electrical equipment you can link to the noise. So turn off the fluorescent lights, for example–if the noise goes away, start looking for the bad fixture.
Does this ONLY happen when there are multiple mics turned on? If so, then it’s possible they’re interfering with each other–that being the case, you can start switching channels around. How close are the receivers to each other? Sometimes receivers that are stacked closely together can also cause problems.
Anyone get a new cell phone recently? This doesn’t sound like GSM noise, but it’s always possible.

Hi Kerrar–can you be more specific? Are you looking for recommendations for complete systems? Cameras? Switchers? Computers? Software? What kind of productions are you streaming–presentations? You mentioned videoconferencing too–what are your needs there?
The good folks on this site can probably be more helpful if you detail what you’re trying to accomplish, and what tools you need help with. Otherwise, we’re all just guessing what you need!

The first thing I would check would be that there’s no RF interference–most receivers have the ability to scan for clean frequencies, and then set the transmitters to match. Also, I note that it’s happening on two channels, so it might be worth checking to make sure that those two mics aren’t set to the same or similar channels, thus interfering with each other.
How about the batteries in the mic packs? Are they nice and charged? Sometimes weird things happen on a struggling low battery.
