Saving Media Cache to External Hard Drive

Apr 10, 2013 2:54 PM

Tags: #pro #premiere #cs6

I have a very large project for my senior thesis film that I am editing in Premiere Pro CS6. I have all 200GB of video files organized on my external hard drive.

 

I use my laptop, my co-editor's laptop, and several of the school's Macs to edit. Each time I use one of these computers, the project has to conform the audio and generate a peak file, which is very time consuming. Often, it will also make me locate several of the video files form my project (sometimes all of them), which is also an issue.

 

I finally figured out the language of this to find in the forums that some people suggested changing the Media Cache files and the Media Cache Database to the external hard drive. When I contacted Adobe Live Chat, the representative cautioned me not to do that because:

So allegedly, that will break the workflow of Premiere Pro...

 

Instead, they had me go into Project>Project Manager and change the settings for "Resulting Project" from "Create New Trimmed Project" to "Collect Files and Copy to New Location."

 

This results in all of the video files that I have imported into the project being copied to the same folder that the project file is in. This seems counterintuitive because all of my video files and media are located on the same external hard drive already.

 

This is what I would like to redirect to my external hard drive:

My question is this: Are there any risks with saving the Media Cache files and the Media Cache Database to the external hard drive? Was the representative correct in that it can cause the project and Premiere to crash and not open?

    I think he/she was just saying that that's not really an intended workflow, so if it DOES crash or lead to other problems, ppro can't really be responsible for that.

    I dont know of any open issues where the app will crash or badly misbehave if you change the location for Media Cache Files to an external drive or elsewhere. But your media cache directory already different from your project and/or media directory by default, so I don't fully understand your goal... Is it to have all the media cache files off of you c <root. drive to save space?

    I would be surprised if that were true.

    I use external HDD's often, to migrate my projects between my PC's (laptop and workstation), BUT set up my Projects with Copies of all Imported Assets, and Media Cache (all Scratch Disks) that way initially. I have never tried to move things around, after a Project has been started (I would explore using Project Manager for such a task). On my PC's, each external HDD is set to the same exact drive letter, in the OS of each computer. With Mac's, that is very similar to "Volumes," but I think that there are some differences. Sorry, but I am a PC-only guy, so maybe a Mac-person can direct you better in that regard. To date (remember, I do this in the initial setup), I have had no lost Renders, CFA's, PEK's, or any crashes, or hangs.

     

    Good luck,

    Yes, that makes sense. If you're talking about media cache files in the sense of previews (cfa, pek, mpeg) that get saved with the proeject by default, then you should have no issues at all. I work off external drives almost exclusively and have had no issues, but then I usally set up my projects that way on the first place. If you're talking about the media cahce database (with a default path like: users\username\library\app support\adobe\common) then I can see why it could prompt some issues if saved externally, but there are none that I know of. I say try it and see how it goes. If it starts crashing all the time then I guess tech support was right and we were wrong.

    Have you had/heard of any experience where someone tried this?

    Yes. I just tried it. = no crash

    Will the Media Cache Files alone accomplish what I am looking to do?

    Yes. But I think you're better off moving the whole project over there, opening it once, then regenerating everything, save it, and delete the old stuff. This is why tech support suggested using the copy & collect feature in the project manager. But as you noticed, it won't respect all your subfolders. So if that's important then just copy everything manually and make new previews for it all as a one time deal.

    I meant move the whole project to your external drive. Isn't it on your local system already and you want to get it off of there? The preview files are stored wherever the project is by default.

    Really?  I refrained from answering because I thought you covered it perfectly.

    My measly >140 character post was (as the OP indicated)

    not particularly relevant in the avalanche of advice that followed.

     

    I will abstain from future expressions of humility.

    Will I have to redirect the Media Cache Files to that location on my external hard drive when I open the project on a new computer?

     

    Yes if you want to use the same one you had locally. I don't think that's necessary though. Previews files are usually what you need to generate for playback and they're already in a folder next to your project file (unless you pref'd them to be elsewhere).
