Optimizing Adobe Premiere Pro settings for smooth playback with LucidLink Filespaces

  • Updated


1. Ensure the Renderer is set to GPU Acceleration

Go to File > Project Settings, and make sure the Renderer is set to GPU Acceleration (if any). If your GPU is cable of hardware decoding you will see it in the drop-down menu (or greyed out and already selected)



2. Lower playback resolution


Adjust the setting to 1/2 or 1/4 in the bottom-right corner of the Preview Window. 

You can also make sure High-Quality Playback is disabled. Click on the Wrench icon right next to the Resolution setting, then make sure High-Quality Playback is unchecked. 



3. Automatic audio waveform generation



To take advantage of the streaming capabilities built into LucidLink, it may be necessary to disable 'Automatic audio waveform generation' in Adobe Premiere. If enabled, Adobe will pre-read all video assets to draw audio wave forms on the screen. This negates the utility of streaming on-demand. Note that when disabled, audio wave forms will still be drawn upon specific video segment playback. 

4. Media cache location

In Preferences, scroll down to Media Cache to change the cache file location, preferably an internal SSD - for the best playback performance. 


5. Scratch Disks / Optimizing scratch disk performance

Under Project Settings, navigate to Scratch Disks in order to change the scratch disk’s file location to specify which disks Premiere Pro uses for media files. Setup the scratch disks when you set up a new project. By default Premiere will set the scratch disks location to the same volume where the project file is.

If you create a project on your Filespace the scratch disks location will also be the Filespace. The scratch disk space increases as sequences become longer or more complex. For best performance choose the fastest local disk for the scratch disks preferably other than the disk where you keep your project file, operating system files, or the files for applications. That way your media disks can access and play media files as fast as possible, without having contention from other processes. 

For optimum performance, follow these guidelines:

  • On Windows, specify only partitions formatted for the NTFS file format as scratch disks. On Mac OS, use partitions formatted for Mac OS Extended (APFS). FAT32/ExFAT partitions do not perform well with big video files.
  • Specify your fastest hard disks for capturing footage and storing scratch files. 
  • Avoid using removable media * because Premiere Pro always requires access to scratch disk files. Scratch disk files are preserved for each project, even when you close the project. They are reused when you reopen the project associated with them. If scratch disk files are stored on removable media and the media are removed from the drive, the scratch disk is not available to Premiere Pro.




6. Automatically Refresh Growing Files

Under Project Settings, navigate to  Automatically Refresh Growing Files. This is a setting typically used for live broadcast productions. To disable it, navigate to Media under Preferences.  




7. Optimize Rendering for Performance
Allocate as much memory you can spare to ensure Premiere has enough spare RAM for utilization.




8. Mercury Transmitter 

If you experience slow RAM preview frame rates when Mercury Transmit is enabled, turn it off or try one or more of the following:

  • Reduce the resolution in the Composition or Preview panel
  • Reduce the RAM preview frame rate in the Preview panel
  • Reduce the project color depth to 16-bpc or 8-bpc
  • Disable color management (set the project’s working space to None).

If none of these make any difference its because you have reached the hardware limit, but you can try another way, which is to use the proxy workflow method:

Ingest proxy workflow

In short, proxies are low-resolution video files that can take the place of larger-resolution video files in your timeline. This is important because low-res files render faster in your video editing app — which is especially useful for RAW and uncompressed video. Editors use proxy workflows when working on large-scale feature projects, just so the computer they’re working on can handle the load. 

Premiere Pro and LucidLink: Ingest Workflow (video)


If you're internet connection is not stable and you still have issues playing video files from your Filespace, you can try the following steps:



This is especially useful when you need to make sure the data is on local disk and you don't want to rely on your internet connection and be dependent on latency and throughput problems.

The LucidLink Cache


​Ensure you have sufficient free disk space available or change where your cache is stored on local or external disk. Because the LucidLink cache is accessed in a random read/write manner, it is strongly recommended you locate the data cache on an SSD as putting it on a traditional hard disk will negatively impact performance to a large degree.

  • On Windows, specify only partitions formatted for the NTFS file format as scratch disks. On Mac OS, use partitions formatted for Mac OS Extended or (APFS). FAT32/ExFAT partitions do not perform well with big video files.
  • When using external drive for LucidLink cache, make sure the device is always plugged in before starting the Lucid app. If the drive is disconnected the Lucid app will inform you that the cache location cannot be found and you will be prompted to re-select the cache location *Introduced with LucidLink Client version 2.0.3774
