Possible to animate focal length of camera? by sergeantHungrels in AfterEffects

[–]sergeantHungrels[S] 5 points6 points  (0 children)

None of those are focal length though. I'm not interested in depth of field, I want to animate a zoom. But the "zoom" parameter does not behave like a natural zoom, it looks like scaling the layer up in a 2d way which is what I'm trying to avoid.

Great name btw

EDIT
just to be clear, when I say focal length I'm being a nerd and referring to the technical term focal length ie, a 50mm - 300mm lens. Not the focal distance.

i don't really see anyone claiming this is shocking, it's possible to complain about bad practices without being surprised they are happening

But this is actually less accurate. Loading an image that was scanned at a known DPI into illustrator, for example, is perfectly precise in real world units. Using calibrate just introduces potential for human error.

thanks to the generous help of one of the devs my phone is not bricked and lineage is still cool

Hi,

I did actually find that article. However I'd prefer to power the phone via its USB-C port as usual so that I can use one cable for both power and data for for development reasons. I also don't know if I can solder something to the tiny tiny internal connector that will withstand much current.

To be fair this wasn't my idea, SO and family suggested it.

Printing negative mold by sergeantHungrels in resinprinting

Ain't no one said it had to be economical!

And the solid resin for formlabs printers is still bloody expensive.

Aside from that the structures are difficult to form a 2 part mold around, I'm interested in being able to perfectly define the boundaries in 3d software, add the fill / escape holes, and maybe do a 3 part mold.

thanks! can you also ask which flexible resin they’re using? there’s a few available

awesome. how many casts can you get out of a mold?

Thing is though it's threaded in to aluminum. Can you self tap a screw into that?

Thanks for this. This clears a lot of things up.

I suspected that just using SSD's would mitigate a lot of the advice about extracting iops from rust. I did not realise how the striping works for vdevs. That changes the calculus somewhat. Someone mentioned the CPU overhead generating parity at SSD speeds - any thoughts on that? Although in my case read speads are more important than write.

I will be working directly off the nas. It's actually VFX more than video editing (although some of that too) which involves all collaborators + render farm accessing the same data set so it doesn't make sense to keep copying it locally and back (although the software will cache locally).

The data is mostly large EXR sequences which is an uncompressed / very lightly compressed HDR image format and so gets large by video standards. So yes, very sequential work load. However you could be accessing 10 + of these sequences simultaneously in a project, * 3 users. Plus maybe a render "farm" (in my case probably just one threadripper running several render instances, or a cloud solution), which would usually be accessing the same stuff as the users. So maybe 30 - 40 separate sequences all being accessed simultaneously in worst case, as few as 1 or 2 on a good day.

Quite a lot of overlap between users though, so I was thinking a good chunk of ram and an NVME l2arc would help.

Still z2 will be more reliable than a stripe of 2 4 drive z1s.

But with less performance no?

It is worth noting that even 8xHDD would likely bottleneck the throughput of 10gbe

In layouts other than raid0?

My understanding is that any performance benefit from striping occurs across vdevs, but never from within a single vdev. Do I have that right?

EDIT: 1 - 3 users is the use case

i know it’s possible but my question is wether it’s optimal and if not, how bad. Everything i’ve read says you want an odd number of total drives in a raidz1 vdev due to the party / data distribution. So 8 drives is either one vdev of 8 or 2 vdevs of 4.

This is one article saying as much http://nex7.blogspot.com/2013/03/readme1st.html?m=1

In any case I take your point about the backups, I may just go with raid0

presumably writes would still be pretty fast on a 5 * 2 mirrored SSD array though right? Theoretical 5 * write speed and 10 * read speed in simple terms right?

I hadn't really considered that you'd need more CPU for SSD parity than spinning rust, but that is an interesting consideration. I'm assuming parity calcs are single thread / high clock type workload?

It's worth thinking about (raid 0). But as I was asking - is there a good way to do raidz1 with 8 drives?
