The terms below appear throughout the Sequence docs. Where a term has its own page, follow the link for the full picture — this page is the quick lookup.
AAF (Advanced Authoring Format) — An interchange file that carries a timeline and its media references between editing systems and audio tools. Sequence exports AAF for audio work in Pro Tools or Avid Media Composer. See Export an AAF for audio conform.
Chroma key — Removing a solid-color background (usually green) so another image can show through behind the subject. See Key out a green screen.
Codec — An algorithm that compresses and decompresses video. The codec determines file size, quality, and how smoothly footage edits. See Supported media formats.
Conform — Rebuilding an edit in another system so every cut, clip, and timing matches the original timeline. Conform work is why Sequence exports timeline packages. See Timeline packages.
Downmix — Combining multiple audio channels into fewer channels — for example, folding surround sound into stereo. See Passthrough and downmix for nested audio.
EDL (Edit Decision List) — A plain-text list of a timeline's cuts, readable by nearly every editing and color system.
Handles — Extra frames of source media beyond a clip's in and out points, kept so you can trim, slip, or add transitions later. See Advanced trimming.
IRE — A unit for measuring video signal level on a waveform scope, where 0 IRE is black and 100 IRE is peak white. See Video scopes.
Log footage — Camera footage recorded with a flat, low-contrast curve to preserve dynamic range, meant to be color-corrected before viewing. A camera conversion LUT brings it back to a standard color space. See Apply LUTs.
LUFS (Loudness Units relative to Full Scale) — The standard measure of perceived loudness used for broadcast and streaming delivery. Sequence's Loudness effect normalizes clips toward a LUFS target. See Audio effects.
LUT (lookup table) — A file that remaps every color in an image to a new one, used to convert camera footage to a standard color space or to apply a stylized look. See Apply LUTs.
Multicam — A clip that groups synchronized camera angles of the same scene so you can cut between them. See Multicam editing.
NLE (non-linear editor) — A digital editing system that lets you jump to any frame instantly, with no need to play through footage in order. Sequence is an NLE; so are the desktop tools it exchanges timelines with.
OTIO (OpenTimelineIO) — An open interchange format that describes a timeline's structure so other editing tools can read it. See Export to OpenTimelineIO.
Passthrough — Keeping the original audio channels as they are, instead of remixing them to a different channel layout. See Passthrough and downmix for nested audio.
Rec 709 — The standard color space for HD video — the range of colors an ordinary display expects. Camera conversion LUTs target Rec 709. See Apply LUTs.
Screening — A shareable review link for a cut or export, where collaborators and guests can watch and comment. See Create and share a screening.
Subclip — A shorter range marked inside a longer source clip, saved so you can reuse it without re-trimming.
Timecode — A frame-accurate clock position (hours, minutes, seconds, frames) used to address exact moments in media.
Watermark — A visible overlay burned into playback or downloads to discourage redistribution of unreleased work. See Screening settings.
