Below are my thoughts from a video newbie, but I became obsessed with this and spent lots and lots of time learning all I could...
Well, I've been fooling around with this for the past 6 months or so. I'm on my 3rd camcorder. 1st was SD tape based, second was HD tape based, and the one I just got now is HD Card based.
I got the Panasonic HC-V720.
A few things I discovered, for me. Forget about the high quality settings. I want a camera that works good at the low quality, so the file size is manageable, and no further processing is required to share to youtube.
This camera on its worst quality setting records at 1920x1080, 60i frames, and a bit rate of 4Mbps. The highest setting is 1920x1080, 60p frames, 28Mbps. There are 3 settings in between. When I record pool and hook the camera up to my 55" tv via HDMI cable, the highest setting looks just "slightly" better than the worst setting. In other words, the lowest file size setting is well above and beyond what is good, imo. In fact, I wish the camera had an even lower setting of maybe between 1 and 2 Mbps.
Now, at this lowest quality setting, I can take the video file off the card, and upload it right to Youtube. When I was using the tape based camcorders, I'd have to import the footage into iMovie (I was actually recording it live to my hard drive, but that is irrelevant here), and then encode those files into something smaller to share to youtube, because they were HUGE (like 30 GB for 1 hr). It took over night to encode in 1080 size. Now with the new camera, that already encodes at that format, I skip these huge time consuming steps.
This particular camera has no remote control, but you can control it from iOS device, and that works pretty well as a remote control.
Problems I'm having:
1. Viewing recorded footage:
I have to physically take the camera off the wall and hook it up to my plasma tv with an HDMI cable. This is of course a pain.
2. I can remove the card and put it in my laptop slot, and then save the video files to the computer hard drive. Then I can play the videos on my computer, or upload to youtube. This still requires a trip up the ladder, to remove the card.
3. I can hook up a long USB cable between the camcorder and the laptop, and copy the files off the card to the computer that way. I STILL have to take a trip up the ladder to touch the camera's touch screen in this method, or the files won't copy over, and I can't use the iOS remote function to complete this step.
The files themselves are in AVCHD format, which is a bit cryptic to find on the card (at least on a Mac, don't know about the PC side).
This was one thing I really liked about the tape based camcorders (which means they use Firewire). There were zero trips up and down the ladder, because the firewire cable recorded whatever was live on the camera directly to the computers hard drive. This had its own set of problems, but it definitely eliminated trips up the ladder.
So now, what I'm looking at is an HDMI capture card. This would hook the HDMI output of the camera directly to my laptop's hard drive. The capture card bypasses the cameras compression mechanism, and sends completely uncompressed video to the computer (like 300 GB per hr). But there is software available that will compress that just like the internal camera chip does on the fly. And I think that will have any data rate of compression you desire.
So thats my next step, that will enable the camera to be controlled by the computer, and files to be saved to the computer on the fly, eliminating all ladder trips, and encoding the file in a format and bit rate that I deem good for personal archiving on hard drive, and also good enough for youtupe without re-encoding.
I'm about to order the "Blackmagic Design UltraStudio Mini Recorder Capture Device". If this works, its $140, and will work with any camcorder with HDMI out, which is almost all of them made in the last 5 years. It also comes with the software I was talking abut earlier.
The downside to this method, is I might have to upgrade my entire computer and hard drive system to be workable. So I'm not sure I will do it. As I currently have an old computer dedicated just to the pool recordings. This capture card method won't work with that computer. It will work with my everyday computer, but then I don't want to tie that guy up to the camera...
So those have been some of my experiences, and I'm certain won't be my last, lol
