It depends largely on what footage you use, I have an old slow (2010) macbook air (although with 4GB memory)
It can handle a long form documentary (xdcam ex), though you have to be a little masochistic to edit that way.

Present mba’s have thunderbolt/usb3 so input/output is no problem and with an external monitor, you will okay as long as you don’t have edit too much or too complicated .h264 /.h265 stuf.

hope it helps

Hi

ProrezHQ with AAC audio encoding is a bit odd combination, maybe you should try to import a prorez file without audio or with uncompressed 16 bit audio/ or 24 bit for that matter. Just render a minute add the .mov extension and try again

hope it helps

Sorry for responding a bit late. Iam somewhere in Russia now and can’t get to my corrections.
Somehow the problem is not in the diffeent clipnames, maybe the problem is that some clips don’t have reelnames.But not beeing able to colortravce (automatically or manually) also affected the clips that had reel names). Well too bad.

I will search further for answers from the 2nd of october.

thanks

xml,

I still use fcp 7. It has it’s problems and so. But as long as premiere doesn’t have the option “show duplicate frames” it is less capable for messy long form films, and they all get messy at some point.

Avid is an option, now you can have more than 8 audio tracks, but still

enfin XML it was

I will try what Sacha suggested again, but i’am afraid I have to solve some kind of dBase issue

thanks

okay

but I was talking about xdcam (Sony) and it worked in Resolve 8

So ?

i’ve similar issues with xdcam-ex footage. In resolve 8.2 I have like 14-15 nodes realtime (osx 10.6.8) and in 9 (beta 1) -osx 10.7.3/2 (?)
I hardly had realtime playback with only 1 simple node (22 fps or so).

In 8.2 I also had less RT when I started up with 10.7 instead of 10.6.8.

I didn’t even switch programs. I just went home and two hours later i found out that only 10 – 20 % was rendered. Restarting and re-rendering helped though. This never happened before, not in 17 years.

Margus, you are right about the big nono and test setups and so

I only mentioned it because it surprises me again and again, that background processes that in itself aren’t processor intensive can have a big impact on performance. -It was not that the browser or flash used 200 cuda cores to render (or half the cpu cycles). Still it slowed playback down as if it was using all this compute.

So maybe there are background and root processes that have a similar impact and if possible could better be shut down. To name a few non vital ones like airport, bluetooth, clock, the dock. ? etc etc. (watch the activity monitor when you have a break and you are doing absolutely nothing).

And maybe there are ways to optimize the system. (o yeah Linux of course)

Admittedly you are right about the accuracy of my little tests, but the projects i tested were similar enough.
and should not give these different results. ( in an ideal world)

Strange as well was that zapping the pram effected the real time playback in the osx 10.7.3 setup, but not in the 10.6.8 setup.

By the way a browser with Flash running can also seriously effect real time playback ( like 8 to 10 nodes in my setup.)

Hope it helps someone with his playback voodoo

[Rene Hazekamp]

That is what I saw, yes. It was not a very scientific test, but anyway. I had like 5-6 more nodes playing back in realtime with 10.6.8 + resolve 8.1 than with 10.7.3 and Resolve 8.1. The only difference was that in the snow leopard version i had cuda 4.0.50 (from memory) and in the lion set up i had the latest cuda driver (well, last fridays).

I’am talking Resolve Lite, xdcam ex 1080p /25 fps macpro 4.1/2.26 gig /8 core/ nvidia gtx 120/470)

the strange thing was that i doubled the realtime playback nodes after zapping the pram -in the Lion setup-
though it came from only 6 nodes rt playback.

I have repeated the results a few times (4-8), but to draw solid conclusions i should do some more tests in some other configurations , – keying, bluring,sharpening whatever-
