Cleaning Media Cache Database Questions

Does cleaning the Media Cache Database only delete the cache and database links for missing files in the current project? Or does it do it for all of your PPro projects located on your computer except the current project you have open?
How do I delete the cache and database links on my Mac for projects that no longer exist? Apparently I can't see the Library directory to where PPro has my Media Cache pointing to. Can only see it if I go through Admin profile.
Many thanks

Bridge's database CAN be quite large, especially if one has a lot of material on the system, that goes into Bridge. I am always a bit surprised at how large those database files can be, over a year's usage.
As I am using Bridge more on a Project basis, with the original Asset files on my NAS, or elsewhere, I can usually safely purge those, when they grow very large - I no longer need those, when the Projects are completed, and the Copies of my Assets are also Deleted from the system.
Good luck,

Taking too long to conform video after cleaning media cache files

So im working on a very large project at the moment and i noticed that the available space on my macbook pro was dramatically decreasing each day, untill i had nothing else left to delete. I eventually found out that the media cache database on adobe premiere pro CC was taking up 560GB. Perhaps prematurely, I decided to clean the cache.
Now after loading up my project, it is re conforming each piece of video and seems to get stuck on one particular video and is taking hours and hours and hours. Is there any way around this? I fear ill be waiting a very long time until I can carry on editing the video.
Thanks

Wow thanks Jim. I copied the files over to my 2TB hard drive and it worked fine!
The old hard drive I was using was something like 200gb but75% full - I did have scratch disks set to the new HDD but anyway - this worked perfectly thanks
Time for a new HDD methinks . . .

Media Cache Database and running out of disk space

Adobe enthusiast here, still learning about PP CS6:
I was running out of space on my c: drive and under preferences in PP...Media...I found the location was set to my AppData folder\Roaming\Adobe\Common\
This AppData folder had nearly 1/2 of my entire hard drive space used.
I clicked the 'Clean' button and I got back a lot of space.
Can I choose another drive and folder for my Media Cache Database?
Is there going to be a problem since I clicked on the clean button?

Clearing the Media Cache Database

Hi, In a tutorial on using Encore CS6 it says to "clear the media cache database"
Why is this done? ...and if done... does it remove any important files, clips, assets..etc that are in my other projects? Is it safe to do this?
Thanks

PPro and Encore create MANY temporary files, which may be deleted when you are done with the project... your original video clips and project files are in a location of your choosing, not in the cache folders
Some more on locations http://forums.adobe.com/thread/1007934?tstart=0
And, one way to design your project http://forums.adobe.com/thread/919388?tstart=0
I always create my project files on my 2nd hard drive (see below) so the temporary files are also put on that drive
My 3 hard drives for video editing are configured as...
1 - 320Gig Boot for Win7 64bit Pro and ALL program installs (2)
2 - 320Gig data for Win7 paging swap file and video project files
When I create a project on #2 drive, the various work files follow,
so my boot drive is not used for the media cache folders and files
3 - 1Terabyte data for all video files... input & output files (1)
(1) for faster input/output if you have 4 drives
- use drive 3 for all source files
- use drive 4 for all output files
(2) only 60Gig used, for Win7 & CS5 MC & MS Office & other smaller programs

Priemere Pro consistantly crashed upon export, I cleaned media cache and that seemed to help. Now export errors unknown problem... read to uninstall and reinstall and now I can not open up PPCS5

Here is my problems with Premiere Pro CS5
When I export a project... the computer crashes.
I was able to get a tech chat and they would clean the media cache
so I did that.
Then, I got an export error "unknown problem" I then read in a forum to uninstall and reinstall Premiere pro
Now on my very nice relatively newer IMAC, when I go to applications to open it... I can not find a purple tab to open it. It just has a presets folder, then open that and it has styles, templates, textures but, now little purple Pr to open or drag to my dashboard.
Help PLEASE!!! I have wasted 20 hours of editing time, and work because of crashes, and problems.

Media Cache vs. Media Cache Database

And why would the "Save media cache files next to original" be of any use??
Within CS4, i'm trying to understand the differences between the two..
If understanding how cache files work, i'm sure many of the users problems would be fixed, and performance improved.
Is there any references or .PDF's to show me how CS4 works with cache files, and how they effect the projects?
This is very important information, and i can't believe I haven't found anything concrete...
Just breadcrumbs of information on the boards here..
Thanx...

I highly recommend you read the 11g New Features Guide. Here is a sample from it:
h4. 1.11.2.9 Query Result Cache
A separate shared memory pool is now used for storing and retrieving
cached results. Query retrieval from the query result cache is faster
than rerunning the query. Frequently executed queries will see
performance improvements when using the query result cache.
The new query result cache enables explicit caching of results in
database memory. Subsequent queries using the cached results will
experience significant performance improvements.

IOS - Library/Cache - Database question

Hello there,
Some time ago I've read on this forum that the correct directory to use on iOS for storing data is Library/Cache and since then I've fixed my app to use that directory.
Here it is the link to an article written by "our" Saumitra:
http://www.saumitrabhave.com/2011/11/air-ios-solving-apps-must-follow-ios.html
My app has 2 db files (and some xml files).
The struct looks like this:
[root] my main app
├──data
│ └──dbtemplates (this dir contains my two db files)
└──xml
   ├──en (this dir contains english localization)
   └──it (this dir contains italian localization)
When my app starts, it copies these 2 db files in Library/Cache directory and then the app fills them with data generated on the fly: from that moment my app will use these two new databases for reading and saving datas.
My questions are:
1) With this struct, is it true that my app won't be rejected by Apple? (I mean with data/dbtemplates, xml/it and xml/en subdirectories)
2) Is the Library/Cache the right directory to copy my new db in?
3) If Apple accepts my app, sooner or later I will develop an update to my app: in that case, if the user has not uninstalled my app, when he updates the app from the apple store, the db files that I stored in Library/Cache won't be deleted from the update process, true?
Unilt today I was pretty sure that the answers to my questions were "yes", "yes" and "yes" but today I've spoken with a friend of mine that told me that I need also to flag my dbfiles as "do not backup" and the only wat to accomplish this is to use a native extension:
http://www.jampot.ie/ane/ane-ios-data-storage-set-donotbackup-attribute-for-ios5-native-ex tension/
Can someone clear my doubts?
Thanks in advance

1) With this struct, is it true that my app won't be rejected by Apple? (I mean with data/dbtemplates, xml/it and xml/en subdirectories)
     Its seems absolutely fine. data and xml are the folders you package as assets right?
2) Is the Library/Cache the right directory to copy my new db in?
     As I see your use case, I think you should rather use the applicationStorageDirectory. Because thes files are essential for your application to work.
3) If Apple accepts my app, sooner or later I will develop an update to my app: in that case, if the user has not uninstalled my app, when he updates the app from the apple store, the db files that I stored in Library/Cache won't be deleted from the update process, true?
     No. As per Apple QnA "the entire <Application_Home>/Library directory has always been preserved during updates and backups, except for <Application_Home>/Library/Caches." See this . So if you store the XMLs in Caches they will be deleted but Not if you store them in applicationStorageDirectory which is (Library/Application Support/....) See recommended usage of this directory here
About "Do Not Backup Attribute".
As you can see that above link mentions adding the do not backup extended attribute to "Application Support". You should set it if you dont need those files to be backed up but, You should not set this attribute if it is essential for your application to have those files when restored from backup to function properly or get "restored" completely.

Automatic Delele Media Cache content (DOMAIN USERS)

Hello,
I would like to know if theres any way to configure an automatic delete for the media cache content?
I ask that 'cause in our production we have 40 machines, each one with several user domains accounts and, if the don't set a limit for the media cache folder in each one preferences, the system disk will get full every time.
Or maybe some configuration that set up a default media cache preferences for all users (without need to log on with the user on each machine and configure that).
Looking forward some reply.
Regards,
Antonio Victor

Media Cache Database is shared between Adobe Media Encoder, After Effects, Premiere Pro and Encore. If you change path to Media Cache and/or Media Cache Files folder(s) in one application, changes are automatically reflected in all other ones. None of Adobe application is currently capable of cleaning Media Cache Database entirely (i.e. correctly), hence you need to do that at OS level (either manually or via scheduled tasks etc.).
By the way, you may probably want to permanently change Media Cache Database location from OS drive to another one.

Media Cache / Media Database / Conforming

Hello, I want to know how the above three files mentioned are different from each other. And I generally do 2-3 projects editing same time, so is it possible that all these 3 files should be
assingned different place for each project.

Conformed (audio) files go into the Media Cache Files. The Media Cache (Database) contains pointers (.MCDB) to the Media Cache files, conformed (.cfa) files and .pek files.
Assigning a location is set in the preferences, not on a project basis.

How to relocate media cache folder?

For User with SSD "C" drives the cache file quickly fill the drive; therefore, it would be advantageous to relocate the cache storage to a Data drive. I have yet to find a way to manage this task.

DrTompkins
Please check out Edit Menu/Preferences/Scratch Disks and the Media Cache category in particular. In the preference you can point the Media Cache (Conformed Audio Files) to hard drive save location of your choice. Note - in preferences you will see the current location of the Media Cache Files Folder as well as the amount of free hard drive space at that location.
While you are in the preferences, check out the other categories, location and free hard drive space at that location. See specially Video Previews. At its hard drive location, you will find the preview files that are automatically generated each time you render Timeline content...for SD, dv.avi and for HD, MPEG2.mpg (same formats whether the preview is from video or still source...they can pile up significantly).
There is also Edit Menu/Preferences/Media and its Media Cache Database area. Best use the Clean button there for maintenance purposes. This relates to the Media Cache Files Folder in the location Users\Owner\AppData\Roaming\Adobe\Common and in the Common Folder is the Media Cache Files Folder that contains the conformed video files (mcdb).
This Media Cache Files Folder seems to return/regenerate anew to its default location no matter how hard you try to redirect it.
Any questions or need clarification on any of the above, please do not hesitate to ask.
Thank you.

Media cache files: Premiere Elements 9 with SSD

Hello you fine Adobe people.
I apologize if this has been asked before, if so please could somebody direct me to an answer?
I have Premiere Elements 9 on Windows 7. My issue is pretty simple: my shiny new SSD is getting full of temp files from the "C:\Users\XXX\AppData\Roaming\Adobe\Common\Media Cache Files" location every time I work on a project. I have set all other cache items I can see in "Preferences" to my mechanical disk, but I am alarmed to see this folder filling up with huge files on my SSD. Aside from the unneccessary reads and writes, it will be filled up in no time. It seems in Premiere Pro you can direct this folder to an external drive, but I cannot find this option in Premiere Elements.
Please tell me there is a way to move the media cache files directory to another drive than C:\ ?
Thank you in advance
A Craven

The answer is that you need Premiere Elements answers for Premiere Elements questions.
The conformed audio files (cfa and pek) are stored in the Media Cache Files Folder. By default, that folder is found in Windows 7, 8, or 8.1 64 bit.
Libraries/Documents/Adobe/Premiere Elements/10 (if 10 is your version). You set the save location for the Media Cache Files Folder in Premiere Elements Editor workspace Edit Menu/Preferences/Scratch Disks and the "Media Cache" category.
The conformed video files (mcdb) are can be accessed via the Premiere Elements Editor workspace Edit Menu/Preferences/Media and its Media Cache Database area. There you will find a Clean up to clear them and set limits. The actual files (which have a .mcdb file extension) can be found via the path shown in that area. This appears to be an unchangeable location.
Preview files from rendering of Timeline content to get the best possible preview at play back of the Timeline content in the Edit area monitor are stored in the Adobe Premiere Elements Previews File Folder. By default, that folder is found in Windows 7, 8, or 8.1 64 bit Libaries/Documents/Adobe/Premiere Elements/10 (if 10 is your version). You set that save location for the Adobe Premiere Elements Elements Previews File Folder in Premiere Elements Editor workspace Edit Menu/Preferences/Scratch Disks and the Video Previews category.
Please let us know if you are now clear about Premiere Elements and how it relates to Media Cache et al.
Please ask if any further questions on this or need clarification.

Media Cache Files? Do I need them?

I was checking what's taking place of my hard drive and found about 22 GB of hard disk space occupied from this folder
C:\Users\Me\AppData\Roaming\Adobe\Common\Media Cache Files
In this Media Cache Files folder there were 459 files of type .cfa and .pek files. 13 of the .cfa files were about 1.6 GB size each
What are these files for and do I need to keep them?

Read about 'em:
http://help.adobe.com/en_US/premierepro/cs/using/WSa41b87baf39dd9b0-4a7aee25125bce32690-80 00.html
Bottom line, if you clean the media cache using one of the apps (Encore or Premiere for example) and the source files are still on line, it won't delete them. You can manually delete those pek and cfa, and if you open a project with those files, it will recreate them.
Note that Encore help only says:
Clean Database . Frees up additional disc space by removing old files in the media cache database shared by Adobe audio and video applications. The database tracks media accelerator files that improve performance and speed. For example, if Adobe Premiere Pro creates a conformed audio file, and you import media with that audio into Encore, Encore uses the file from Adobe Premiere Pro instead of creating a new conformed file. The media cache database informs Encore of the conformed file’s location.

Premiere Pro CC and Media Cache

Hello!
I've read the documentation on Media Cache (http://help.adobe.com/en_US/premierepro/cs/using/WSF08BCDDB-FCD7-40a2-8290-8872EE725E6B.ht ml#WSa41b87baf39dd9b0-4a7aee25125bce32690-8000) but I didn't understandt what are exactly the formats/containers that Premiere Pro creates cache for?
Also, am I remembering wrong, but was in Premiere Pro CS 5.5 and CS 6 the cache for the project was kept in the same folder as the project?
Does Premiere clean the Media Cache regularly or I have to remember to do it from time to time?

I don't think that much has changed regarding the treatment of cache files from CS5 to CS6 to CC.
Here's how I manage the cache files:
1) Set Premiere to store media cache and media cache database in a drive folder separate from your project files (use menu: Edit / Preferences / Media and then browse to where you want them - I use "X:\premiere_cache"). This way, when you back up projects you are not backing all of this stuff up too.
2) They do not clean up for themselves - go to the same panel mentioned in #1 and click the "clean" button to remove all of the files. When Premiere Pro is closed, you can manually delete all of the folders created by Premiere and you will not destroy anything that is recoverable.
The purpose of cache files is to prepare some files additional your projects and media for performance enhancing reasons.
Regards,
Jim

Trying to move the Media Cache Folder

I have the current version of Premiere Pro CC on OSX 10.9.4. I want to move my media cache files and media cache database folder from the default, USERS/LIBRARY/APPLICATION SUPPORT/ADOBE/COMMON to my external media scratch drive. I have changed this in my settings, and I can see cache files building up in the new directory. However, somehow, new media cache files are still being put in the old cache files and database folders. It is as if some are going to the new, some are going to to old. Any reason fro this and any way to chance it? I want no caching to happen on my internal system drive, I want all to be external.
Just found something odd - I tried making a brand new media cache directory on my scratch drive after resetting the premiere pro prefs. Now, premiere is putting cache files in this new one, the previous one I created on my media drive, and on my system folder. Is this a bug?

Just curious, are you still having this issue?

Media cache files do I check the save media box

I am trying to optimize my system and under the preferences under media it is set to the default on the C: drive. Here is my setup I have a 1TB C:\ for OS and programs and four 1TB drives setup Raid 5 which is my D:\ drive and 24GB of Ram. If I understand correctly I should set my Media cache files and Media cache Database to the D:\ drive? If I check Save media files next to originals dose this do the same thing? Also with 24GB of ram what and where should I set my pagefile to?

Your raid is nearly three times faster than your boot disk, so I would put the media cache files next to your projects on the raid. With 24 GB memory, the location of the pagefile is not really important, since it will hardly be used, due to the good memory management of PR. If you use on-board IHCR, you may put the pagefile on C because the IHCR is pretty slow in comparison to a dedicated controller.
