Few things to look out for:
1. Are you using drone footage? DJI codecs lag the hell out of systems.
2. Obvious: make sure your frame rates are all similar. If you have different frame rate footage, just click on the footage in your media browser and “interpret footage” all the same rate. This will lag it for sure.
3. Your playback: If you are using the regular set up, its a Mpeg playback. If you are working with pro-res footage or RAW, you will need to change your playback to a custom setting. Generally something 1920×1080 or smaller.
4. Usually its codec for me. If I am working with the GH5 .mp5 footage, and mixed with pro-res footage it will lag much more then a full pro res workflow. You can try doing Proxie Files. Just search Premier Pro using Proxie files. This always helps and probably better to learn it sooner then later.
Super hope this helped.
