One common reason is using variable frame rate (VFR) videos, which are often recorded on smartphones and can make playback choppy. Other factors that can cause lag include using highly compressed video formats like H.264 or HEVC, having a buildup of media cache files, and working with effects that haven’t been rendered yet. In this article, we will discuss different ways to solve this error.
1. Check Image Sizes (If Applicable)
The first thing you should do when troubleshooting lag in Adobe Premiere Pro is to check the size of any images used in your project. Sometimes, images that are much larger than your sequence or project can slow down playback and cause lag. When image files are unnecessarily large, Premiere Pro has to process more data, making playback less smooth. To avoid this, use images that match your project’s needs and resolution. Review the images in your project, and if any are too large, resize them and replace them in your timeline. Make sure to remove the old, larger image files from your project to fully resolve the issue.
2. Lower Playback Resolution
High playback resolution settings in Adobe Premiere Pro can also cause playback lag. This is because higher resolutions require more decoding and processing power, which may overwhelm less powerful computers. To improve performance, lower the playback resolution. This reduces the amount of data Premiere Pro needs to process in real time, resulting in smoother playback.
3. Optimize Rendering for Performance
Adobe Premiere Pro includes a setting that allows you to optimize rendering either for memory usage or for maximum performance. When memory is prioritized, Premiere Pro may run more slowly if the available memory is limited.
4. Turn Off Hardware Accelerated Decoding
Premiere Pro offers hardware-accelerated decoding to improve playback performance, especially when working with H.264/AVC or HEVC video formats. However, if you are not using these formats, or if your hardware doesn’t fully support them, this option can sometimes cause lag.
5. Change Default Audio Input
The default audio input setting in Premiere Pro can sometimes cause lag or stuttering, usually because of conflicts with audio drivers or certain webcam drivers, like EpocCam. Changing the default audio input to “None” in the preferences may resolve playback lag in some cases.
6. Turn On GPU Acceleration
Adobe Premiere Pro can use your GPU (graphics card) to help process effects, rendering, and other tasks, which can greatly enhance performance. By default, the CPU handles most tasks, but enabling GPU acceleration can offload some of the work to your graphics card, making playback smoother. If the GPU Acceleration option appears greyed out in your project settings, you may need to update your graphics drivers.
7. Delete Media Cache
Sometimes, old or very large media cache files in Premiere Pro can slow down performance. The media cache helps the program load files faster, but when it gets too large, it can actually cause lag.
8. Reset Premiere Pro Preferences
Over time, custom preferences in Premiere Pro can slow down the application, causing lags and stutters. Resetting your preferences can often resolve these performance issues and get Premiere Pro running smoothly again.
