'Media Cache Files' is a folder that can be deleted. If you delete and use any of projects listed in this folder, the program will just need to regenerate the cache files for them. This is not a folder that you need on a day-to-day basis. Check out Motion Array: quick tutorial on how to delete media cache files from Adobe Premiere Pro and After Effects.

This document provides information on how to troubleshoot linking and importing errors while importing audio files.

Identify linking and importing errors with audio files

When you try to import audio files like AVCHD (MTS), MP3, and MP4 files in your project using Premiere Pro, you could get an error message that says, 'The file has an unsupported compression type.' This error is sometimes noticed with other Adobe audio and video products like After Effects and Media Encoder.

Delete Adobe Media Cache Files

The cache files of imported video and audio files in Adobe Premiere Pro are stored in Media Cache Files folder on your computer. When this folder gets too large or has any corrupt file/s, it might be the reason videos won't play in the program. When importing video and audio into Adobe Premiere Pro, it processes versions of these files that it can readily access for faster performance. These are referred to as 'media cache' files.

  1. When you see an error, 'The file has an unsupported compression type', check the Media cache and the Media cache database in Premiere Pro.

  2. Select Edit Menu>Preferences>Media Cache Database on Windows OS or Premiere Pro menu > Preferences > Media Cache Database on Mac OS. Make a note of this location.


  3. Close Premiere Pro and other Adobe audio & video applications.

  4. Navigate to the Media Cache location specified under Premiere Pro > Preferences and rename the folders, Media Cache file, and Media Cache. Select Clean to clean the media cache database folder.

  5. Launch Premiere Pro and attempt to import your files.

  6. If you still see an issue, change the file directory where the AVCHD files reside and check if the issue gets resolved. For example, if the folder structure is:

    AVCHD>BDMV>STREAM>.MTS0000

    Create another folder, XYZ, and move the contents of the AVCHD folder to XYZ folder.

    Note:

    Ensure that the folder structure of the MTS files is identical to the original folder.

  7. If the error persists, the issue could be related to activation.

  8. Check if you are using a trial version of Adobe Premiere Pro. If you are using a trial version, you would experience problems with importing AVCHD and MP4 files as the required .dll files are not installed in the location, C:UsersPublicPublic DocumentsAdobeInstalledCodecs. Upgrade to a paid creative cloud membership.

  9. Select C:UsersPublicPublic DocumentsAdobeInstalledCodecs.

  10. Rename the folder, AdobeInstalledCodecs to another name.

Get the best performance out Adobe Premiere Pro by following these expert tips from a seasoned video editor.

Adobe Premiere Pro CC certainly isn't the most stable or glitch-free NLE on the market, but it is one of the fastest, most robust, and codec friendly software offerings. And if you're like me, you'll take your software a bit glitchy as long as it's the most cutting edge and performance driven.

The best way to get the best performance from Premiere is to use ProRes Proxy files…but the client needs this edit tomorrow and there's no time to transcode everything! We need to start editing now and we need Premiere to be able to keep up with our blazing fast editing skillz!!! So let's discuss how to squeeze the most performance out of our favorite, crash loving software:

1. Enable GPU Previewing

Premiere can realtime preview video in 3 different ways: CPU (software only), OpenCL (AMD graphics cards), and CUDA (Nvidia graphics cards). By default, software only is selected because not all systems have graphics cards. If your system doesn't have a dedicated GPU (graphics card) then you won't be able to select the GPU Acceleration options and you will be forced to stick with the subpar Software Only setting.

If you do have a dedicated GPU, which is definitely preferable, then you should select a GPU Acceleration option. To change this setting go to File/Project Settings/General… then use the Renderer dropdown menu to select your preference. If you have an AMD GPU then select OpenCL rendering. If you have an Nvidia GPU then select CUDA.

Note that Nvidia GPUs with more CUDA cores will have better performance so definitely purchase cards that have the highest number of CUDA cores that you can afford. Also, if you have an Nvidia GPU, then make sure to install the CUDA driver and keep it up to date. Nvidia CUDA for the win!

2. Point Media Cache to Different Drive from OS

By default, your Media Cache files are stored on your OS drive. This works fine and all, but it's not optimal for performance because you want your OS drive to be focused on delivering its best read/write performance to your OS and your applications.

Instead of allocating these precious resources to your OS drive, move your Cache to a separate drive. When I build systems, I always dedicate a 500GB SSD strictly for cache purposes and I point the cache files to that drive. The faster the cache drive, the better. So try to use an SSD or even better an M.2 SSD. If you insist on using a spinning disk drive then at least use a 7200rpm drive.

3. Decrease Preview Resolution if Necessary

Premiere does its best to realtime preview your timeline so that you don't have to transcode your videos or wait on render previews. However, even with a fast computer and GPU, sometimes what you have going on in your timeline is still too much to handle and you will notice stuttering video and laggy performance.

If this happens, try reducing your preview resolution located on your Program monitor window. Doing this is typically necessary for RAW footage; unless you have a beastly system! Furthermore, unless your program monitor is displayed full screen, there is typically no need to preview in full resolution because your monitor probably can't display all of the video pixels anyway (i.e. your timeline preview monitor is only occupying the upper right portion of your computer monitor).

4. Disable Clips When Not In Use

Premiere previews the top video track layer of your timeline. It stands to reason that if you have multiple clips on video tracks below your top layer then performance should not be affected since only the top track is previewing…right?…WRONG! Even clips underneath the top layer video track use up system resources and will slow down performance. Download office mac free trial.

Instead of being destructive and deleting these clips, simply right click and uncheck the Enable option in order to disable the clip. This will ensure that you can use this clip again if you so choose to by re-enabling it; but in the meantime it won't take up resources and slow down your timeline preview.

Pro tip: use the keyboard shortcut cmd+shift+e (ctrl+shift+e on Windows) to enable and disable clips instead of right clicking.

5. Edit in a Sequence that Matches Your Footage Settings

Premiere performs best when previewing a sequence that matches the native properties of your footage. Therefore, when you create your sequence, you should right click on an imported clip and select New Sequence From Clip.

Premiere will then create a new sequence that matches the resolution, codec, and frame rate of your clip. I know that many of you are thinking 'But I like to make a 1080p sequence and import my 4K video so I can downscale it in order to reframe.' Doing this is a great practice and certainly much better than upscaling (never upscale!) but all that downscaling takes a performance hit on Premiere.

Instead, I recommend doing all of your edits in native resolution and then once you're ready to do your reframes, create a new 1080p sequence and copy and paste the contents from your native sequence into your new 1080p sequence. Then do all of your reframes because at that point you won't care as much if your video is stuttering since all of your edits are done and you're just fine-tuning.

BONUS TIP: Use an Adjustment Layer for Color Correcting

To create an adjustment layer, your Project window must first be selected (it should be highlighted by a thin blue box), then select File/New/Adjustment Layer… Premiere will then create an adjustment layer file in your project window that you can insert into your timeline. An adjustment layer affects all layers that are below it so keep this in mind when you're editing because you may not want your graphics to be affected by the color corrections of your adjustment layer. If this is the case, simply put your graphics above your adjustment layer.

Adjustment layers are great because they are an easy way to on/off your color grade at a universal level (instead of going into the effect controls of each clip independently). There is a performance benefit to this as well because if you want to watch your timeline for the edits then you want to see it playback as smoothly as possible so simply eyeball off your adjustment layer and watch your timeline playback like butter. Then, when you're ready to tweak the grade, simply eyeball back on your adjustment layer.

Another way adjustment layers can benefit performance is if your sequence resolution is lower than your clip resolution because adjustment layers are based on your sequence resolution. Therefore, all of the effects on your adjustment layer will be rendered at the lower resolution of your sequence, rather than being rendered at the higher resolution of your clips.
