how to clear media cache in Premiere Pro

Use TrackMatteKey in PremierePro to control the display range of another layer through the brightness or transparency of one layer. 1. Commonly used in scenes such as text masking, graphic outline display, and video embedding medium shape; 2. Setting steps include: putting the content video on the upper layer, putting the mask layer down layer, applying TrackMatteKey and setting Matte to the lower layer; 3. Supporting two modes: LumaMatte (based on brightness) and AlphaMatte (based on transparency), and you can check the Reverse inverting mask effect. Master the layer order, Matte type selection and Reverse status to achieve diverse creative effects.

Use the Replace with AfterEffects Synthesis feature in PremierePro to enable fast and fine color tuning and special effects processing. 1. Make sure that PremierePro and AfterEffects are the same CC suite and are compatible with the version. Right-click the clip and select "Replace with AfterEffects Synthesis". The DynamicLink plug-in must be installed for the first time; 2. This function packages the selected content into AE synthesis and creates a dynamic link file, replaces the original clip location, retains all effects and transitions, and PR is automatically refreshed after AE modification and saving; 3. When using it, you need to pay attention to keeping the project structure clear, avoid frequent nesting, preview performance problems and the consistent material path; 4. Suitable for adding mask animations

There are three ways to adjust the playback resolution in PremierePro. First, modify the default playback resolution through "Sequence Settings". After opening the project, click "Sequence" > "Sequence Settings" in the top menu, and select the required resolution such as 1/2, 1/4 or custom ratio to save it; second, temporarily adjust the playback resolution, you can click the setting icon in the lower right corner of the program monitor and select "Scaling Scale" or "Resolution" to achieve it; third, adjust the global playback performance settings, and configure the proxy format, hardware accelerated decoding and playback performance options through "File" > "Project Settings" > "Media Collection and Cache" to optimize the smoothness of high-resolution video playback.

There are four ways to add text in PremierePro. First, use the "Text Tool" to directly add and adjust the style; second, create a new text layer through the "Graphics" panel for easy layer management; third, adjust text styles and animations, use built-in templates or manually keyframes; finally, enhance readability, which can be achieved by adding background boxes or strokes.

To export video or image sequences with transparent channels from PremierePro, you need to select Alpha formats such as QuickTime animation encoding, ProRes4444 or PNG sequences; correctly set and check the "PreserveTransparency" option in MediaEncoder; make sure the background in the timeline is transparent and uses compatibility effects; pay attention to the compatibility issues between the player and import tools, such as QuickTimePlayer supports but Windows MediaPlayer does not, and the Alpha channel needs to be manually enabled when importing AfterEffects.

Adding dynamic blur in PremierePro can be achieved in four steps: 1. Add DirectionalBlur or TransformBlur to video clips and adjust the direction and blur length to enhance dynamics; 2. Enable the MotionBlur button on the timeline for clips with zoom, displacement or rotation animation to generate a real blur effect based on motion; 3. Turn on the MotionBlur option when using WarpStabilizer for anti-shake to retain natural dynamics; 4. Pay attention to select whether to use blur according to the content, turn off proxy mode, and avoid lag caused by multiple layers of blur superposition. Mastering these methods can effectively improve the realistic and smoothness of the video.
