About Source clips

When you import media into Premiere, each file is converted into a source clip in the Project panel. A source clip represents the original media asset, and every time you add it to a sequence, Premiere creates a sequence clip that references the same underlying file. This structure allows you to reuse the same media across multiple sequences while maintaining a single point of reference in your project.

Source clips are always managed from the Project panel and don't exist inside a sequence. Sequence clips inherit the media from their source but can be edited, trimmed, layered, and adjusted independently within the timeline.

Premiere supports applying source-level video effects directly to a source clip. When you add an effect to a source clip, all sequence clips derived from it automatically inherit that effect. These global effects appear in the Source tab of the Effect Controls panel when the clip is selected in the Project panel. Only video effects are supported at this level.

Certain effects cannot be applied to source clips. Intrinsic effects such as Motion, Opacity, and Speed, along with effects like Warp Stabilizer and Rolling Shutter Repair, are available only on sequence clips in the timeline and don't appear in the Source tab. Audio effects are also not supported at the source-clip level.

For some formats, especially camera RAW media, source clips include Source Settings that allow you to adjust properties such as exposure, color temperature, or gamma before editing. These adjustments apply globally to every timeline instance and provide a consistent foundation for further grading.
