First of all, excuse my inactivity the last weeks. But I really had a busy time, I think there will be a lot of interesting stuff coming up, including my new show reel, within the next couple of days (I can not promise it, but I will try hard). But the busy time connects perfectly to my topic today: system maintenance.
I thought of making this a kind of open letter to producers, asking them to calculate time for system maintenance within their timetables for productions, but I think that would make no sense (if you ever heard the sentence “We will fix it in post!” you know what I mean!). They simply do not understand the need to keep a NLE clean (I know there are pleasant exceptions, but my experience shows me that the very least know the importance of system maintenance). And some of us - editors - do not do, too. I mean, even in the old days with 3-VCR edit suites you had to keep your workspace clean, keep the tapes sorted and label them correctly. Which leads me to my first point:
Always keep your projects organized in a way that any other editor could step up and start to work. By that I mean everything from naming your footage, naming tapes in the “Capture Tool” (if you ever had to batch capture you will know why you should name your tapes in a way that they can be found again in the future), even giving effects that you saved a unique name so you can find the one you need in your bins.
Keep your sequence organized as well. Basically, keep the video tracks as simple as possible. Organize your audio tracks in a rational manner: place the the speaker/overvoice on A1, the natural tone on A2, music on A3 & A4, sound effects on A5 & A6 and so on.
If the company you are working for has any guidelines and/or sample-projects or workflows: that is a good thing, even if you have to get yourself used to it. It will make everyday work a lot easier.
And after you finished your work you have to clean up your desk, right?
Get used to the “Media Tool”! It is the media organization tool in MC. Within it you will be able to find each and every item MC has created. You can sort them by hard disk, project and three different kinds of media:
“Master Clips”: not actually media files, but the metadata collection of a clip. Master clips contain tape name, time code, resolution, the location of the media if online, and so on.
“Precompute Clips”: all kinds of rendered files, from mere renders to imported (graphic) files.
“Media Files”: the name speaks for itself, all media files connected to “Master Clips”.
You can, and you should, delete most of the “Precompute Clips” regularly, even when you are in the middle of a project. You can do that without any danger of “offlining” anything if you follow my advice closely: open the “Media Tool”, check that only “Precompute Clips” is marked, click on “All Drives” and “Current Project”. What you will get is a full list of any renders and imports of your current project (surprise, surprise). Now you will have to do a bit of hand work: if you have imported files into your project, such as Quicktimes or AVIs, you will find them with the “Precomputes”. You do not want to delete them, since then you would have to batch import them. Also, you do not want to delete titles that are still in use, they can be retrieved relatively easy but it is a waste of time, in my opinion. But you can safely delete everything with dissolve in its name, for example. If you have long renders, such as a TC burn in, you might want to delete those to. Or Color Corrections, blurs and so on (you will have to look for the names of your effects in the name of the “Precomputes”. In the MC helpfile search for the term “sifting”. With “sifting” you can improve your workflow when dealing with large bins extremely, and the Media Tool is quite often a large bin). You will not lose the effects, they simply will get unrendered and you might have to render them again to play them back in real time. But as a benefit you will get rid of unneeded renders, a faster responding system and disk space. Although disk space must not be an issue nowadays you might run into low disk space and now you know what you can delete without actually losing something.
If you still use OMFI-Mediafiles, for whatever reason, you should really have an eye on how many media files you got. You will run into problems when you have more then 10.000 files in your OMFI-folder. So deleting “Precomputes” is vital when working with OMFI-Mediafiles.
OK, so now that we have talked about the “Media Tool” already, let us say you have completed a job and laid your final sequence to tape.
How to clean up your workspace?
First, make a copy of the project folder to a backup location. This can be a shared network drive, an external hard disk, an optical media such as CD or DVD or what ever. I highly recommend saving your backups of any kind on a mirrored RAID-system, so in case one hard disk dies you can access your backups anyway.
Now, open the “Media Tool”, choose the “All Drives” and the “Current Project” options, check that all three types of media (“Master Clips”, “Precompute Clips” and “Media Files”) are enabled and click OK. In the “Media Tool” hit CTRL+A (command+A on the MAC) to select all items in the “Media Tool” and press delete. As always when deleting things in MC the system will ask you if you are serious about deleting. Double-check you have a copy of the project folder as a backup, then tell ‘em you are and there we go. Everything is gone.
Now open every bin in MC, again hit CTRL+A then “DELETE” to delete all items that were left back by the “Media Tool” in all bins. Why? Because the “Media Tool” sees only what the databases show and if your databases are confused it could be that you have not deleted every media file with the “Media Tool”. If you miss to delete a couple of files with multiple projects they can accumulate to a lot of dissipated disk space and lots of files. Then quit MC and delete the original project folder.
There is a tool out there called MDV (although the homepage is partly in Russian language the program is translated to English) which many people over in the Avid Forums like to use. I have not tested it yet but I did not want to keep that information from you. But I think one should first understand Avids own media management: the “Media Tool”, before using third party applications.
Any other suggestions to keep an Avid system fly and clean are highly welcome!
