Thunderbolt4 with an external NVME can outperform internal storage (even NVME) on Apple silicon based MACS. Many people are successfully using MIni Macs with Da Vinci.
To be honest, in my experience, Thunderbolt 4 is good, but I still have to use proxy’s to get any sort of decent playback at times.
It can be very frustrating, and I’m told Apple Mac’s have no issues what so ever, even at 4K 30fps!
Thats exactly what I do. However for some reason the Jamie Fenn stuff never works for me. I follow it to a tee but the result never works. Other ones tend to though.
Daniel Batal is my favourite; quick, no-frills, and great at explaining the steps succinctly.

Moved your post, and the replies, to the relevant thread, since it had no direct relevance to recent releases and update.
Already posted in this thread. 
Way too long! My attention deficit would kick in after 10 minutes! 
Small bites is the answer. Could make that last a week. 
Not actually watched, myself .. even though there is still something I’d learn from it if I did.
Currently battling a change in Fusion’s 3D_Camera_Tracker, that wasn’t mentioned in the latest release and seems to be undocumented.
Done a load of tests in the two latest versions (which is a pain in itself, unintalling and reinstalling) .. and it most definitely has changed .. to the point that you can’t re-run the a tracker, created in 20.1, in 20.2. Have to start all over … which, on my lame laptop, is >24 hours chugging away for a 2 minute clip.
Will be posting my findings to the DR forum tomorrow .. nobody else (at my last check this morning) has made mention of it.
Hmmmm, I’ll look into that. I used the Planar tracker, stabilizer and transform in fusion on a clip in my last video, but wasn’t entirely happy with it. Didn’t use it but I think I kept the render in my media. 
The Fusion 3D Camera Tracker is absolutely nothing to do with any of the other trackers. It’s all about moving the scene into a 3D model.
Ah, not my thing that, I have trouble with the 2D shit, let alone 3D!
Yes I watched the previous and the new one is pretty much the same as the last. The edit / fusion stuff on there doesn’t cover such technicalities either.
I have varying results with Trackers. All too often the box veers off at tangents, or the image/text judders. Makes no difference how good a contrast the selected area has either, its hit and miss.
I find them pretty accurate, myself.
Mostly it works, but have had to re start the fusion clip on occasion where the point wanders, or “vibrates”
Me too! Magic mask 2 is another marvel but not as flawless as they make out TBH.
Strange. In the colour tab I reckon Magic Mask is awesome .. the new version. The old was no slouch.
My laptop doesn’t like the Fusion version they’ve just introduced. It selects perfectly, but DR crashes after tracking a few frames. That’ll be my almost 10 year old tech laptop, though .. nothing wrong with DR.
A shame, because had I been able to do everything in Fusion it would have been a load easier. So had to overlay the Fusion clip on the timeline with an original clip that had the appropriate “cutouts” using Magic Mask in the colour tab.
Worked flawlessly, that way .. right through the 2 minute clip.
@OzoneVibe Maybe, I was asking too much, Dave. I was using to mask a church tower that I’d or orbited around in stong sunlight. I was using keyframes to equalise the light and contrast as I went from light to shadow. Even after adding strokes etc throughout the clip it was flickering at the edges and no amount of adjustment hid it. I need to learn a tad more I reckon!
Had similar on one I’m currently working on .. in “Faster” mode, but was really tight in “Better” mode .. even if that took a lot longer on the old laptop, it was worth the wait.
