It means 'SuperSpeed' i.e. USB3 at 5 or 10 Gbit/s (the plastic parts of the connectors are also often colored blue). For reference 'High Speed' USB is 480 Mbit/s and 'Full Speed' USB is 12 Mbit/s. Note that while some USB-C connectors and cables support 'SuperSpeed', not all do (cheap cables in particular often don't support more than 480 Mbit/s). The 'SuperSpeed' connection uses separate wires in the cable, and it's cheaper to leave them out. So if buying a cable, check carefully that it supports SuperSpeed (5 or 10 Gbit/s) data rates if you need them. In my experience, most PC/Laptop USB-C ports are SuperSpeed-capable but peripheral devices to plug into them are a complete mixture of speed capability. Personally, no, but I almost always buy Sandisk or Samsung, and always 'sold by Amazon' i.e. not from marketplace sellers. I've never needed to buy a UHS-2 card, so no advice on that.

From dpreview's video test chart, OM-1 vs G9ii (both at 24p/25p/30p) - they are very close on resolution/sharpness: ....but on OM-1 is 50p/60p much softer than 24p/25p/30p - note the softness of the middle bar at 60p vs 24p/25p/30p : Those test results match what I've found when using the OM-1 for real-world video.

It is - provided you hold the camera reasonably still, otherwise you get jerks if you move it too fast. It's the mode I normally use for wildlife video with that lens. The extra crop that digital stabilization adds is actually useful in that situation too.

Yes, probably more than you really need - and sometimes several ways of doing the same thing (but annoyingly there are a few things that would be really useful to assign to a camera function button but you can't...). Photo and Movie modes are (mostly) separate worlds, including the function button settings.

If anyone is interested, this is a comparison I did of various OM-1 IBIS settings and Panasonic 'Power OIS' lens stabilization. All handheld, all C4K@50p video, using Panasonic 100-300mm f4.0-5.6 II lens at 100mm and 300mm. I was standing still, the camera was handheld, using the EVF, with my left hand underneath the lens and right hand holding the camera body.

It's also got a 4-stop ND filter:

From the press release on dpreview: ...and from the Fuji product page:

AFAIK, after a 'full reset' of the settings (see 'Shooting menu 1 -> Reset/Custom modes -> Reset -> Full), it defaults to using card slot 1 for everything. As this is a used camera, I'd recommend doing a 'full reset' anyway - the options are so complicated that you don't want someone else's preferences to start from...

I feel the same about the ZV-1 - I bought it mainly as a pocket-sized video camera, but I'm actually liking the stills from it more (I find the video quality is a bit so-so). Turning it on/off by opening/closing the screen is a great time-saving idea. I'm also finding the S9 + 18-40 lens quite fun - the limited amount of buttons and dials (and no EVF) means there's fewer decisions to make, so it becomes more of a point-and-shoot experience (and in traditional Panasonic style, you can set it up to shoot basic shutter-priority video when using the record button in photo mode - no need to operate a photo/video switch first). Almost the perfect hybrid for me.

C4K/UHD 60p is softer on the OM-1 than 24/25/30p - see this dpreview video stills comparison Sharpest video modes are C4K/UHD at 24/25/30p 10-bit. Re. the IBIS performance - I don't own any manual lenses, so can't test the IBIS in that situation, but I often use non-stabilized long telephoto lenses like the Oly 75-300mm and Pana 100-300mm (with lens OIS turned off) for wildlife video. With the video stabilization 'IS Level' set to +1 (the highest setting) I can get usable handheld video at 300mm provided I'm leaning against something or sitting down to provide a bit of extra stability. Is the video stabilization working OK with native MFT lenses? If not, I'd suggest doing an 'Initialize All Settings' and starting again (especially if this is a used camera). Note that some of the stabilization settings are separate for stills and video, so you might need to set the manual lens focal length separately for stills and video:

After sitting on the fence for while, after the recent price reductions and a 'used - like new' deal popping up, I bought that combo. Handles rather like a slightly larger and heavier GX85, with much better video quality and C-AF - pretty much as I hoped/expected. That would be nice - but I suspect the more expensive S-series cams would get that first (if it happens at all).

I bought the S9 + 18-40mm kit as a 'used - like new' deal recently in the UK for about £1100 (including 20% sales tax). With the recent price reductions that kit is only £1299 brand new (and only £150 more than the body alone). Quite liking it so far, feels very solid in the hand and the lack of a front grip isn't as much of a problem as I thought it might be. Pretty good value (at the current pricing) for what you get, I think.

...and in L-mount, there's always the Pana S9 - not much larger and heavier than the Fp (both fitted with the Pana 18-40mm collapsible zoom below) - and you get IBIS too:

I think pretty much any sector on social media (unless it's very, very niche) is going to be saturated with content. All you can really do is make your content as interesting and easy to watch as possible. If you are going to be on-camera and/or talking to the audience it'll probably take lots of practice and time to develop your 'presentation style' unless you have a natural talent for it. Those things are far more important than small differences in picture quality between cameras etc. that your viewers won't notice. Don't over-think the hardware side of things and buy extra stuff that you think you *might* need (and then waste time working out how to use it) - the KISS principle.
