FCPX developers, please optimize disk access
Hello,
I was editing large project with about 500 clips on timeline.
All media files (ProRes FullHD) I copied from internal to external drive and relinked all clips from timeline to external drive. Event and Project folders remained on my internal drive.External drive was connected via USB and then I realized how often is FCPX accessing original media 🙁
I’m using latest 10.0.5 version and with my large project (500 clips, 3 hours video) FCPX was accessing original media after EVERY EDIT action I did.
It was not problem with smaller projects, but with this large project it was really pain to see disk working 15 seconds after every edit action.
It was also working when I selected clip on timeline and hit Cmd-C 🙁My question: why is FCPX always accessing original media? Is it necessary always checking clips used on timeline?
Thank you

USB2 or USB3?

When you choose to optimize media, it creates the ProRes files. Once the media is optimized, it automatically switches over and refers to the new optimized (pro res) media files. The media should definitely be on an external drive but you should stick with firewire (or thunderbolt).

Why optimize when my timeline is ProRes422 and media files are too?
Why is FCPX so heavily accessing all media files with every edit?
It’s not problem to buy thunderbolt external RAID. But what if I will have 30 hours timeline with 5000 clips?
All I ask is to optimize this step. I think that FCPX is doing something unnecessarily.

I don’t understand the issue. If you are editing with the media linked to the original files (which is what is sounds like you are doing), then yes, original media will be accessed with every edit. That’s the way every NLE works. USB is too slow to efficiently work with HD media.

Yes, it’s my case.
But why it is so? Why it is accessing all clips? What is it checking? If they still exist? Alter every edit?
If I append new clip to the end of timeline how does it affect existing clips on timeline?I hope taht FCPX developers read this thread and make some little change 🙂
I want to help make FCPX even better. -
In order to play a clip a NLE needs to access the media that is linked to the timeline. How else would it play?
Also when you edit it needs to know about the clip. If you have thumbnails and audio waveforms visible in the timeline, those need to be updated as well, this is done by reading the media and analyzing it.
If your HD’s and system is slow try editing proxy media. USB2 with ProRes would be pretty slow, possible even unwatchable.
I hope this helps a little.

I understand you, but my example:
Timeline has displayed all waveforms, disk is quiet. Then I trim last clip by one frame from right. Disk is working 15 seconds and then it is quiet again. Then I trim same clip by one frame again and disk is working another 15 seconds. I don’t think that it is optimal behaviour and I don’t understand reason for this disk activity.
Remember – disk contains media clips only. No project or event files.

It sounds like your disc is going to sleep and when you access the clips it waking back up.

No, it’s not going to sleep.
