Baffling RT Extreme Error
I’ve encountered a strange dropped frame error in one of my projects in FCP. Basically, at a certain point in the timeline, I keep getting the following dropped frames message:
“RT Extreme determined dropped frames were caused by slow discs. Try: Increasing speed of discs, Decreasing # of RT layers, Limiting your RT bandwidth in User Preferences.”
The timeline section in question occurs at the beginning of a nested sequence that is part of a larger sequence with other nested sequences before and after. I’ve even tried cutting and pasting the timeline audio/video instead of nesting, still no dice. All nested sequences are rendered prior to nesting. I also have “Safe RT” selected and my RT limited in preferences. Basically, whenever I move the playhead over the selected area and play it, it freezes.
One other note: I have some QT files that I use regularly stored on an external Medea Firefly firewire drive and one of the files it pulls from the drive is located in a video clip right before it drops frames. The part of the nested sequence that”s playing when it freezes is a file from Motion I export as QT Movie, DV NTSC Movie. But I don’t have other problems with freezing when I play out exported Motion movies in FCP, so I didn’t think that was the problem.
I have no idea what’s going on. I’ve got a brand new Mac Pro with 5 GHz Ram, so I doubt my machine should be locking up because of lack of ram. I also just created this FCP system based on the Jerry Hofmann article “Achieving a Rock Solid FCP System” and this is the first time I’ve dropped frames seriously.
Any help would be appreciated. My specs are below.
Thanks,

Check your Sequence > Render All and Sequence > Render Selection menus. Put a check mark next to ALL of the items (including the audio ones) and especially the one marked ‘full’. Then hit option-r to render all realtime effects. Then select your whole timeline (apple-a) and the hit apple-option-r. This will mixdown the audio. There’s no doubt your drives aren’t keeping up, especially if you have one file on a little firewire drive. Move that file on your main system.
Do all those and your sequence should play.

How do you move the file to your main system? I am having the same problem I followed your directions and I am still having the problem, except moving the file to the main system.
Please help, thanks. -

Do you have media on your boot drive and your capture drive? If you have media on your boot drive, you should drag it (move it) to your capture drive. Make sense?

ok. i have read the answers to this ?, but I still haven’t a clue how to actually fix it. I am trying to find out if there is any “Media on my boot drive” (not sure how to determine that). My problem seems to have developed after I trashed my preferences in an effort to keep the video from freezing in my canvas and not getting video to my external monitor when I have “ALL FRAMES” checked in “External Video” or only having my time line video play when I have “OFF” checked in “External Video”. Please HELP!!!!!!
