Challenge accepted. I will be back in a year.

It was me who made that comment. Sorry, but how can you not see that it’s stuttering so much. This is a brand new Rhino 8 software recorded with something looking like 10 fps. It’s not only unpleasant to watch it’s unprofessional and shows Rhino like it would barely work. Teenagers making video gameplas can do it, so can you. If cursor stuttering is not enough to spot that wait for the fragment where Rhino’s viewport camera is moving.
The new video about Rhino 8 for Mac is recorded just as badly.

I believe you that you are seeing that on your end…
It’s also true I do not see that here. Both videos play smoothly when I review them. What quality setting are you using for playback in YouTube? These (and every other video I’ve ever done live) are recorded from Gototraining and as such I am stuck with their frame rate for capture.
Just checked the framerate, youtube says it’s 15 fps, independently of the chosen resolution.
(Right click → Stats for nerds)
Don’t know which max fps Gototraining can capture, could be just a setting. Camtasia can capture 25 or 30 fps without problems.
I just watched that video you linked, it played smooth as butter here, maybe there is some kind of trouble with your web browser.
I have the same results on Chrome and Edge, on two different computers and on Android phone.
I didn’t know about these “stats for nerds” that @lemberski showed. I also see @15 here which I believe is about FPS.
Can you please check your stats for nerds?
I just did, for the videos that fit in a single screen and these are my results
I usually watch on my mobile fone and didnt noticed this issue before, but watching on my laptop it became apparent.
What I noticed as well was that, for the videos with good framerate the windows toolbar was not showing, so maybe the recording was set just to the rhino screen (like people usually record games) while the ones with bad framerate showed the windows toolbar on the bottom.
To make it even more complicated (but at least apparent) I checked the Rhino 7 for Mac- Rotary tool video. Statistics are showing 30 fps, but these are clearly not truly different frames.
Please check 53:53 (it should start from that timestamp) camera movement and cursor are stuttering very much.
For comparison, I’m posting a video that plays smoothly.
I can recommend Streamlabs to record the screen.
By accident I stumbled upon someone’s comment under Rhino 7 for Mac- Rotary tool video. So it seems like it might be an “artistic choice”

The “Mastering flow along surface” video plays smoother here at my laptop in Firefox, stats show 24 fps. Don’t know if some browsers (on Android) calculate in-between frames on the fly when the fps drops below a certain level. 15 fps as an “artistic choice” for a video tutorial longer than 5 min? I prefer minimum 24 fps otherwise my attention drains. To make sure: the content is super, just the framerate of the video could be better.
Looks like the recent update of gototraining added this- I’ll fiddle with it and see if we can get some improvement.
I have tried camtasia or other 3rd party captures before and had several malfunctions that caused the loss of the entire video, (or the just the audio, or just the video) so I went back to using gototraining for capture to insure the content was not lost, so far they have not let me down.

for curiosity sake, this is the identical video on the most recent chair video (literally the same file) just uploaded to vimeo instead of you tube… does this show any better for you?
sorry- try this-
These are some popular YouTube channels featuring Rhino:
We can see Rhino in numerous videos when brands show their designers at work, but it’s difficult to find them afterwards. I remember seing Rhino in videos from Trek bicycles, POC helmets, Belkin accessories, etc

I captured a fragment of this video. It looks like it’s barely working.
hmmm… I am seeing it much smoother here.

I just checked the video above and I can also see this video quite choppy. The other video on YouTube, however, was slightly smoother (maybe 15 fps), though not as smooth as a real 30 fps must be.
I record my videos with the integrated screen recording chip of my Nvidia GTX 1660 Ti and it has always performed great during the years! It uses the “GeForce Experience” software that comes with the Nvidia drivers. Since it’s a dedicated chip, it will not affect negatively the 3d rendering performance of the video card. 
The default quality of recording that way is about 99% of what I see on screen. The is only a minor loss with the red colour, which is typical for any compressed digital content. “GeForce Experience” has various settings for the sound recording to use either the external microphone, the system sound, or both.
Here is a sample long video with system sound (microphone sound is turned off), just to show the general smoothness and slight loss of quality after it’s converted by YouTube. YouTube usually does the conversion really fast if the videos are 4K at 30 fps, but the longer (like one hour long or more) 4K/60 fps videos take a lot of waiting. Sometimes even an entire day. This is why I mostly record at 30 fps nowadays.
I also upload videos with various tips and tricks for Rhino on my channel, though they are far less popular than those big commercial channels with millions of views.

All the modelling and the wire frame work is really laggy, but once you turn on rendered mode it is smooth. Both cursor movement and viewport manipulation. Strange stuff, is it silky smooth when you model it?
