I dunno.

 

Perhaps since the upgrade to 10.1, whenever I display the angles, performance drops to zero and everything staggers.

 

Project is 3 and 4 track multicam at 1920 x 1080 on an iMac 2011 with 16 Gb

 

All media is on a 2 Tb external RAID and I'm using Apple ProRes 422 so I don't think proxies will help.

 

Its big ... but it was working before.

 

What can I do ?

 

Thanks

    The only solution I can see is to to drastically reduce the size of displayed windows ...

    I'm not sure what three and four track multican means. How many angles does your project have? What else do you have in your library? How much free space on that RAID? And when you say the media is stored on it, does that mean you also have your libraries on the RAID?

     

    Do you have Background Rendering on or off?

     

    Is Playback set to Better Performance? And if Pro Res isn't working right, I would definitely consider Proxy.

    BTW: Anyone else gettng error messages from Jive when they try quoting from posts?

    Hi Russ,

     

    I have 4 angles and there is 600 Gb free on the RAID.

     

    When you say libraries, do you mean events and projects, now the new unique container? yes they are also on the RAID

     

    How do you set playback for better performance?

    I have optimised media for multicam clips on and background render but I always wait for the render to finish.

    Yes. Now, Events live in Libraries and Projects live in Events. One of the things that seems to affect the app's performance is how much stuff is in a given library,

     

    Payback quality  is now chosen in Viewer Display Options.

     

    Depending on the RAID, four streams of PR 422 could be a slog for FCP and your system. What level RAID is it, what's the model and how's it connected?

    Also,  BG Render affects performance.

    Viewer Display Options seems to help when set to performance.

     

    The RAID is a Western Digital from end 2012 on FireWire 800, I think RAID 0 which I read here is best for performance.

     

    About background render, surely it doesn't take resources if it's not actually rendering?

     

    Is it better to have libraries on the system disk when media is on the RAID?

    Also - can you work in multicam without rendering straight away (BG off) ? I mean not technically but in terms of editing. You have to see how your edit looks before you can move on ...

    Why are you having to render? Does the media not match the project properties?

  • 9. Re: Multicam is impossible
    markfrompluneret Level 1 Level 1 (0 points)

    No it does, but every time I do an edit, it renders in order to get wysywig ... (what you see is what you get !)

  • 10. Re: Multicam is impossible
    Tom Wolsky Level 10 Level 10 (106,220 points)

    Definitely switch off background rendering.

  • 11. Re: Multicam is impossible
    markfrompluneret Level 1 Level 1 (0 points)

    I hear you but then how in practice do you do edits if you have to stop to render anyway?

  • 12. Re: Multicam is impossible
    Tom Wolsky Level 10 Level 10 (106,220 points)

    If you're working with proxies you should be able to play the video without rendering even if rendering is required for output and shows orange. If you can't then there are performance problems with your system. This seems to be plaguging quite a number of people in the new version, but not a great many others. Don't know what can be done about that other than trying the usual, trash prefs, repair permissions, new user.

  • 13. Re: Multicam is impossible
    markfrompluneret Level 1 Level 1 (0 points)

    I thought that Apple Pro Res and XDCAM and a bit of H264 would be okay but also

    I'm not using proxies because I don't have the disk space to store both the original and the proxy

    plus all of the project libraries

     

    but I suppose you can turn off background rendering if you're just doing angle swaps.

    will give it a go, thanks

     

    and will look at your other suggestions re preferences.

    what's that about new user?

    It makes very little difference to have a RAID 0, since your connection is the bottleneck. A single drive can already achieve a throughtput like 120MBps, which is about 50% more than Firewire 800 can handle. With two such drives in a RAID 0, your 240MBps expected throughput is bogged down by a connection that supports only about a third of that.

     

    In summary, your expectations for your RAID, in terms of speed, are way overblown.

     

    The most immediate remedy, to get any decent performance when dealing with four streams in a multicam, is to use proxy media. You need USB3 or Thunderbolt to really benefit from a RAID 0.
