Premiere Pro feeling sluggish? You're not alone. It's a powerful video editing tool, but it can get laggy pretty fast if your setup or workflow isn't optimized. The main culprits are usually your system specs, project settings, media format compatibility, and how you're handling effects or preview files.

Let's break down the most common reasons and what you can do to speed things up.

1. Your Hardware Isn't Up to the Task

Premiere Pro is resource-hungry, especially when working with high-res footage like 4K or higher. If your computer doesn't have enough RAM, a weak GPU, or an older processor, you'll notice lag during playback or editing.

• RAM : 16GB is okay for light projects, but 32GB or more is better for smoother performance.
• GPU : A decent dedicated graphics card (like NVIDIA RTX series or AMD Radeon) makes a huge difference, especially with effects and color grading.
• Storage : Use an SSD instead of an HDD. NVMe drives are even faster and help with loading times and caching.

If you're on a laptop or an older desktop, check Adobe's recommended specs and compare them to what you've got. If you're underpowered, consider upgrading components or offloading some tasks to lighten the load.

2. Wrong Sequence or Playback Settings

Even with good hardware, Premiere can still stutter if your sequence settings don't match your footage or if you're using the wrong playback mode.

Here's what to check:

• Sequence Settings : Right-click your clip in the Project panel > "Set Sequence Frame Rate" and "Set Sequence Resolution" to match your footage.
• Playback Resolution : In the Program Monitor, change the resolution dropdown from "Full" to "Half" or "Quarter." This reduces the workload on your GPU.
• Mercury Playback Engine : Make sure it's set to use GPU acceleration. Go to File > Project Settings > General and confirm that “Mercury Playback Engine GPU Acceleration” is selected.

Mismatched frame rates, resolutions, or relying solely on software rendering can kill performance fast.

3. Heavy Effects and Unoptimized Media

Editing raw 4K footage without proxy files or stacking too many effects/plugins will slow everything down. Premiere has to process all that data in real time, and if your system can't keep up, you get dropped frames and lag.

What you can do:

• Use Proxy Files : Create lower-resolution copies of your clips (like 1080p Pro Res or H.264) and switch between proxies and originals as needed. Premiere has built-in proxy workflows that make this easy.
• Limit Plugins : Too many third-party effects or heavy color grading can bog things down. Try disabling some temporarily to see if performance improves.
• Render Preview Files : Hit Enter to render your timeline. Once rendered, playback should be smooth. Don't forget to delete unused previews later to save space.

Also, some codecs—like H.264 or HEVC—are harder to decode than others. Transcoding to something lighter like Pro Res or DNxHD before editing can reduce strain.

4. Cache and Scratch Disk Issues

Premiere relies heavily on cache files for smooth playback. If your scratch disk is full or located on a slow drive, you'll run into performance issues.

Fixes:

• Set your cache location to a fast drive (preferably an SSD).
• Give it plenty of space—ideally 50GB or more.
• Clear old cache regularly via Preferences > Media Cache .

Also, disable auto-save if you're not actively working on multiple versions of a project. It can write large files to your drive and cause slowdowns.

Lag in Premiere Pro is rarely just one thing—it's usually a mix of factors adding up. Start by checking your hardware and media quality, then tweak settings and optimize your workflow. Most fixes are simple once you know where to look.

基本上就這些。
