I am replying to this old thread,as the app has now been updated and we finally have this functionality, to use the RAM preview like a regular editor. I love how AE can now playback footage in realtime (on my 3xioFX RAID set up anyway).

To get it working:
In the Preview panel:
-Select Spacebar from shortcut
-uncheck cache before playback
-Range = entire duration
-Uncheck If caching play cached frames
-CHECK Move time to Preview time

very useful for adding GFX at the right time quickly.

Now if we can get audio scrubbing to work smoothly while holding ctrl we will be there!

you need to update the bios, then update the thunderbolt driver then update the BMD driver. You can use the z840 page for some of the drivers, not the bios though I assume. it still may not work but then after restarting a few times and unplugged things a bit it will work. Mine is happy now, but I often have to reinstall BMD drivers as often I can’t see mu ultrastudio. You have to start the device quite a bit before the machine

So if normally a 60fps would have 120 shutter speed, if slowing it down, maybe shutter should be 60 to get the right feel of motion blur?
Re. Pulldown interlacing. Oh, yeah, oops, hmmm….

[Tristan Summers]

why wouldn’t it work to 29.97p? there is no interlaced source material

[Tristan Summers]

Think I am understanding something here.
Higher frame rate obviously means the shutter will have to be open for less time.
Hence there will be a lot LESS MOTION BLUR.
So the image gets sharper.
This can lead to MORE stuttering.
If you then lose frames taking it down to 30/25 it gets more choppy

The extra motion blur shooting at 24 actually helps keep it smooth.

24 divides nicely with pull down to 30 and speeds nicely up to 25
You don’t usually notice the extra doubled frames

60 chops nicely in half to 30 but not sure it can be put in to 25 so easily.

But the softening you et with retiming may actually be a good thing and increase motion smoothness

In a time of multiple frame rates, it would be good to get some tutorial references to point towards best practice on this and similar issues.

Noah and I are from a graphics not a shooting background, so we are thinking about timelines not lenses, which may not be helping

Hi
Also, just asking around.
Shooting at 60p, you would need to increase the SHUTTER speed.
I don’t fully understand why.
So the result conforming down will still be stuttery.
Think Gladiator
super sharp
no motion blur to smooth things out
So actually shooting 24p will probably produce better results.
But unless you are familiar with American Cinematographer panning speeds, avoid pans like the f***ing plague
Horizontal camera motion will stutter even if it is super slow.
I don’t think you will need it for this, but just to be aware of…

adding motion blur with TimeWarp can help though
Speed set to 100% but with motion blur on uses optical flow to produce pretty good motion blur. Not as good as Nuke but hey

[Tristan Summers]

Ivan is basically describing 3:2 pulldown
I have some friends with a Scarlet who may be able to help and maybe cheaper and more competent than some of the other more traditional photography options…
I would make the whole thing at 60fps and send it out of house for conversion.
StanleyProductions are the go to place in Soho and not actually that expensive.
But it must be a process people have cracked.
There used to be a process in compressor that was pretty good.

There should be a twistor / kronos ( Timewarp) preset

Anyone?

It is also possible, when going 24 to 25 to time stretch the audio but keep the pitch the same, but you may need to use compressor
For animations I often render each thing separately, but for indents, clients have never understood the need.

Right now a 1080p24 master is enough and easiest to conform as the interpretation rules are already in place…

[Tristan Summers]

Hello Noah!
You have learned well young Jedi
You could shoot 24 fps use normal 3:2 pull down to get the 29.97 and slow it down for 25.

this is how all films are done.

But say it was for something that needed fast motion, you could double that to 48. Then you are in the Hobbit territory.

if you have the budget, shoot it 60p and get it converted at Stanley. It isn’t that expensive.

I did that for multinational delivery for Nokia.

after effects retiming never really works for me but if you use time warp instead it is often better

do it by setting actual frame numbers.

or download Fusion and figure out how to do it there.

UPDATE: Yes it does if you update hardware under Windows 7

RECOMMENDATION: update all drivers and equipment BEFORE updating to Windows 10

WARNING: Other thunderbolt devices may need updating in future under W7/8 so keep back up OS

BMD does not yet support Windows 10 but my Thunderbolt 2 ULTRASTUDIO 4K is now working with HPZ820

GOOD NEWS

[Tristan Summers]

As of October 2015 this is still not supported under Windows 10.
I have seen a lot of people updating workstations to W10 but a word of warning, Windows 10 not supporting thunderbolt yet in HP Z machines
