# Auto B-Roll Source: https://docs.premierecopilot.com/features/auto-broll Transcribes your timeline and places your own b-roll where it illustrates what is being said. Auto B-Roll listens to your edit, looks at every b-roll clip in a folder of your project, and places them on a track above your timeline — wherever the visuals illustrate what's being said. It uses **your own footage**. Nothing is generated, nothing is downloaded from a stock library. Works in **Premiere Pro** and **DaVinci Resolve**. ## Quick Start Put the clips you want available into a project bin. Only bins that actually contain video show up in the picker. Open the **Tools Menu** and select **Auto B-Roll**. Choose it in the dropdown — the field pulses green until you do, because nothing can run without it. **B-roll / min** decides how much b-roll lands on your edit. e.g. *"only nature shots, keep it subtle"*. Click **Add Auto B-Roll** and let it work through its four steps. Your timeline must be under **2 hours** — it gets transcribed, and beyond that the audio export becomes unreliable. ## Settings | Setting | Range | What it does | | ----------------- | ------------------ | ----------------------------- | | **Mode** | Project / Timeline | Where your b-roll comes from. | | **B-roll folder** | your project bins | The pool of clips it can use. | | **B-roll / min** | 1–60 | Density target. | | **Brief** | free text | Creative direction. | ### Mode Pick a project bin full of b-roll. The clips are **added on a new track above your edit**. This is the mode to use. Your b-roll already sits on a video track and gets **moved** to the spots where it fits. Coming soon — currently locked. ### B-roll / min The target is your **timeline duration × this rate**, with a small tolerance. Density is treated as the priority: the AI aims to hit that count rather than holding out for a perfect visual every time. * **2–4** — occasional punctuation. Interviews, corporate, talking-head where the face carries the video. * **5–10** — the standard illustrated-video rhythm. **Start around 8.** * **12+** — dense, fast-cut, montage-heavy. Needs a large, varied b-roll pool to avoid repetition. Density above what your folder can support forces repetition. A rate of 15/min on a 10-minute timeline asks for \~150 placements — with 20 clips available, you'll see each one many times. ## How it matches The run goes through four visible steps: **transcribe the timeline → read and analyze your b-roll → AI matching → place the clips.** What matters for your results: * **Matching is thematic, not literal.** A clip qualifies if it's figurative, evocative or simply related in mood, setting or subject. A city at dusk over a line about ambition is considered a good match, not a mistake. * **Repetition is minimised, not banned.** Clips that haven't been used yet are strongly preferred; a clip comes back only when nothing fresh fits. * **Several clips can stack on one long passage**, up to a small maximum — never on a short one. * **Placements never overlap.** A clip that would run into the next one is shortened, not dropped. * **A clip is never stretched beyond its own length.** Short source clips produce short placements. Your b-roll only needs to be described **once**. Clips already analysed in a previous run are recognised, so re-running — or running on another sequence in the same project — is faster. ## Writing a Good Brief The brief steers the creative direction. It's optional, and short is better. ### What works * **Restrict the pool:** *"Only nature and landscape shots — skip anything with people."* * **Set the tone:** *"Keep it subtle and atmospheric."* / *"Punchy, energetic, on-the-nose."* * **Guide the interpretation:** *"Favour metaphorical matches over literal ones."* / *"Stay literal — show exactly what I'm talking about."* * **Protect passages:** *"No b-roll over the intro or the call to action."* * **Give context:** *"This is a product demo — prefer the office and workshop shots for the process parts."* ### What doesn't work * **How much b-roll to place** — that's the B-roll / min setting. * **Timecodes or exact placements** — *"put the drone shot at 2:15"*. The AI picks the moments; do a specific placement by hand. * **Naming a file** — it works from what the clips *look like*, not from filenames. * **Effects, transitions or speed** — placement only. No fades, no scaling, no reframing. * **Asking for footage you don't have** — it can only use what's in the folder you picked. ### Recommended pattern > *"\[What to include or exclude]. \[Tone]. \[How literal to be]. \[What to leave alone]."* **Example:** > *"Only exterior and nature shots, no faces. Calm and atmospheric. Prefer evocative matches over literal ones. Leave the first 20 seconds clean."* If the results feel repetitive, the fix is usually **more clips in the folder** or **a lower density** — rarely a longer brief. ## Presets The preset bar saves your working configuration, including the mode, folder, track, density, and brief. Build one per format so a recurring series is a two-click job. ## After the run The b-roll lands on a track above your edit as ordinary clips: move, trim, replace or delete anything you disagree with. The underlying edit is untouched. Review it as a pass, not clip by clip: play the timeline once and only stop on placements that actively distract. Auto B-Roll is there to give you a full first layer to prune, which is far faster than building one from scratch. ## Common Pitfalls * **No folder selected** → the Start button stays disabled and the picker pulses. It's the only blocker you can clear yourself. * **Empty bins don't appear** in the picker — only bins containing video are listed. * **Timeline over 2 hours** → refused before anything runs. * **A tiny b-roll folder with a high density** → heavy repetition. Add clips or lower the rate. * **Very short source clips** produce very short placements — that's the source length, not a bug. * **Touching the timeline while it's placing** → let the progress modal finish; it's writing to your sequence. * **Music or noisy audio under the voice** hurts the transcription, and a weak transcript means weak matches. **Recommended workflow:** a well-stocked, varied bin → 8 b-roll/min → a one-line brief → run → prune in one playback pass. # Auto Color Source: https://docs.premierecopilot.com/features/auto-color AI colorist grade of your timeline — exposure, white balance, contrast and a cinematic look, with shots of the same scene matched to each other. Auto Color grades your timeline like a colorist: it looks at an actual frame from every source clip, measures it, corrects the exposure and white balance, sculpts the contrast, and applies a look on top — while keeping shots from the same scene consistent with each other so your cuts don't jump. Works in **Premiere Pro** and **DaVinci Resolve**. ## Quick Start Shooting Log? Apply your **Log → Rec.709 conversion** (LUT or color-space transform) **before** running. Auto Color grades on top of your base image. Open the **Tools Menu** and select **Auto Color**. Type your instruction in the **prompt box** — e.g. *"warm cinematic look, match all the clips"*. Optional, but this is where the creative direction lives. Leave **Time Start** and **Time End** empty to grade the whole timeline. Click **Start Auto Color**. **Log / flat footage without a conversion will not grade well.** Auto Color reads the image it is given: if you hand it a washed-out Log frame, it corrects a washed-out Log frame. Put your LUT or color-space transform on first. ## What it actually does Every source is fingerprinted, then shots that belong to the same scene, lighting setup or camera are grouped so they share one consistent look. Unrelated scenes are deliberately **not** matched — a daylight exterior and a tungsten interior stay separate. Each source is then graded individually: correction first (exposure, white balance, contrast), creative look second — following its group's shared direction when it has one. ### What gets adjusted The grade is a full **Basic Correction** pass, not a two-slider nudge: | Control | What it's used for | | ------------------------ | ------------------------------------------------------------------------------------------ | | **Exposure** | Bring the image to a balanced brightness. | | **Temperature / Tint** | Neutralise the measured color cast — or push it for the look. | | **Contrast** | Add shape, especially on flat footage. | | **Blacks / Whites** | Set the black and white points — this is what makes an image feel filmic instead of milky. | | **Shadows / Highlights** | Open crushed shadows, recover blown highlights. | | **Saturation** | Punch or mute, with skin tones protected. | **One frame per source is analysed**, not one per clip. If the same source appears eight times in your edit, it's analysed once and the grade is applied to all eight instances — consistently, and for the cost of one. ### How it lands on your timeline | Host | Where the grade goes | | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------ | | **Premiere Pro** | On **adjustment layers** placed on an empty video track above your clips — fully non-destructive. Your original clips are untouched. | | **DaVinci Resolve** | Applied per clip on the first node. | In Premiere, hide or delete the adjustment-layer track to see the before/after instantly — and to throw the whole grade away in one move. ## Settings | Setting | What it does | | ------------------ | ----------------------------------------------------- | | **Prompt box** | Free-text creative direction. Overrides the defaults. | | **Time Start (s)** | Only grade clips at or after this time. | | **Time End (s)** | Only grade clips up to this time. | Unlike Auto Mix, the time range here scopes **both the analysis and the grade** — only the clips in the window are looked at. Grading a section on its own means it won't be matched against shots outside the window, so expect it to sit slightly differently from the rest. ## Writing a Good Prompt Describe the **image you want to see**. Reference a mood, a film, a palette — not slider values. ### What works * **A look:** *"Warm cinematic look, teal shadows, film-like contrast."* / *"Clean and neutral, corporate."* / *"Cold, desaturated, moody."* * **A reference:** *"Nordic thriller palette."* / *"Sunny golden-hour vlog feel."* / *"Documentary — natural, no stylisation."* * **Matching intent:** *"Make everything match, it's all one interview."* / *"Keep each location distinct, don't match across scenes."* * **A known problem:** *"My footage is too warm under this lighting, neutralise it."* / *"The interior shots are underexposed."* * **Restraint:** *"Correction only, no creative look."* / *"Subtle — don't push the saturation."* * **Skin priority:** *"Talking head — skin tones are the priority, everything else is secondary."* ### What doesn't work * **Slider values.** *"Set exposure to +0.4"* — say the image is dark instead. * **Per-clip instructions.** *"Make the third shot cooler"* — grade the timeline, then adjust that clip by hand. It's already an editable Lumetri instance. * **Timecodes in the prompt.** Use the Time Start / Time End fields. * **Selective / secondary corrections.** No masks, no power windows, no "only change the sky" or "isolate the red jacket". This is a primary grade. * **Split-toning by name.** *"Teal shadows, orange highlights"* is understood as a direction, but true wheel-based split-toning isn't part of what gets applied — expect the spirit, not the exact technique. * **Fixing the shot.** Clipped highlights that hold no data, heavy noise, or a badly out-of-focus frame can't be recovered by a grade. * **A LUT by name.** *"Apply Kodak 2383"* won't load a LUT. Describe the look and it will be approximated with the correction controls. ### Recommended pattern > *"\[The look you want]. \[Matching intent]. \[Any known problem]. \[How far to push it]."* **Example:** > *"Warm, filmic look with deep blacks — golden-hour feel. All the interview shots are the same setup, match them. The B-roll outside is a bit cold, neutralise it. Keep it subtle, skin must stay natural."* If the first pass overshoots, add one restraint sentence (*"much more subtle, correction-led"*) and re-run, rather than rewriting the whole brief. ## After the run The grade is standard, editable color correction — nothing is baked in. You can retune any shot, copy a grade from one clip to another, or delete it entirely. Review on your cuts, not clip by clip. A grade that looks great in isolation but jumps at a cut is the real failure mode — and it usually means two shots that should have been matched weren't. Say so in the prompt and re-run. ## Common Pitfalls * **Log footage with no conversion applied** → the most common cause of a disappointing result. Convert first. * **An already-graded timeline** → Auto Color adds its own correction on top of yours. Remove your existing grade first, or the two stack. * **Nested sequences** → the clips inside can't be analysed as separate sources. Flatten first. * **Expecting scene-to-scene uniformity** → grouping is deliberately conservative. Different lighting setups stay different unless you explicitly ask to match everything. * **A very large timeline** costs proportionally more: the price scales with the number of **unique sources**, not the number of clips or the duration. * **Frames that can't be exported** (footage offline, media on a blocked or synced folder) are skipped — check your media is online before running. **Recommended workflow:** convert Log → one full pass with a short look-and-matching prompt → review at the cuts → re-run with a restraint or matching correction if needed → hand-tune the two or three shots that still stand out. # Auto Mix Source: https://docs.premierecopilot.com/features/auto-mix AI sound-engineer mix of your whole timeline — levels, EQ, compression, de-noise and music ducking under the voice. Auto Mix listens to every audio clip in your sequence and mixes it like a sound engineer would: it sets each source to a proper loudness target, cleans up the voice, leaves the music alone but puts it at the right level, and rides the music down under every line of dialogue. Everything is applied as **real, editable effects** on your clips — nothing is baked in. Auto Mix is a **Premiere Pro** feature. It is not available in DaVinci Resolve. ## Quick Start Open the **Tools Menu** and select **Auto Mix**. Type your instruction in the **prompt box** at the bottom of the panel — e.g. *"clean podcast mix, keep the music well under the dialogue"*. Optional, but this is where most of the control lives. Leave **Time Start** and **Time End** empty to mix the whole timeline. Click **Start Auto Mix**. Count roughly **one minute per hour of timeline**. ## What it actually does Auto Mix works in two passes, and knowing the difference explains most of the results. Each source clip is identified as **speech**, **music** or **SFX**, then given its own treatment: level, high-pass, compression, de-noise, de-ess, limiter — only what that clip actually needs. Wherever a music or SFX bed overlaps speech, a smooth **volume automation** is written on the bed: it dips before the line starts, holds under it, and comes back up after. ### Level targets Levels are set relative to a delivery standard, with the **voice as the anchor** and everything else placed below it: | Delivery | Speech anchor | | -------------------------------- | ------------- | | **Podcast / voice** (default) | -16 LUFS | | **YouTube / streaming / social** | -14 LUFS | | **Broadcast / TV / EBU R128** | -23 LUFS | Music sits clearly below the voice and is ducked further under it; SFX land in between. Just name your platform in the prompt — *"master for YouTube"*, *"broadcast delivery"* — and the whole mix re-anchors around it. That single word does more than any manual gain pass. ### Processing philosophy * **Voice gets the work.** High-pass to remove rumble, compression only when the delivery is genuinely uneven, de-noise only when there's a real noise floor, de-essing only when it's actually sibilant. * **Music is left alone.** A music bed is already produced and mastered, so it gets a **level and nothing else** — no EQ, no compression. Only its volume moves. * **SFX stay minimal.** Level, and a limiter if a peak demands it. Nothing is applied "just in case". If your voice track is clean and even, you'll get a gain change and a high-pass, and that's it — that's the correct mix, not a missing one. ## Settings | Setting | What it does | | ------------------ | -------------------------------------------------- | | **Prompt box** | Free-text instruction. Overrides the defaults. | | **Time Start (s)** | Apply the mix only to clips at or after this time. | | **Time End (s)** | Apply the mix only to clips up to this time. | **The time range limits where the mix is applied, not what is analysed.** The analysis always reads the whole timeline, so a range still gets levels consistent with the rest of your sequence. This is deliberate — mixing a 30-second window in isolation would make it jump against its neighbours. Use the range to fix one problematic section after a first full pass, rather than re-mixing everything. ## Writing a Good Prompt The prompt is optional, but it's how you set intent. Describe the **result you want to hear**, not the parameters. ### What works * **The delivery target:** *"Master for YouTube."* / *"Broadcast delivery, EBU R128."* * **The music/voice balance:** *"Keep the music very low under the dialogue, it should barely be there."* / *"The music can stay present between the lines."* * **The overall character:** *"Clean, neutral podcast mix."* / *"Punchy and loud, energetic edit."* / *"Natural and dynamic, don't squash it."* * **A known problem with the recording:** *"There's air conditioning in the background, clean it up."* / *"I'm sibilant, tame the S sounds."* / *"My delivery goes from whisper to shout, even it out."* * **What to protect:** *"Don't touch the music, only fix the voice."* / *"Don't over-compress, keep the dynamics."* * **Ducking behaviour:** *"Duck the music hard under every line."* / *"Only light ducking, this is a music-led video."* ### What doesn't work * **Per-clip instructions.** *"Lower the third clip by 3 dB"* is a local retouch — do it by hand, or ask the Copilot for that single clip. Auto Mix is a whole-timeline pass. * **Timecodes.** *"Boost the intro at 0:15"* — use the Time Start / Time End fields instead. * **Creative sound design.** No reverb, delay, pitch, telephone effect, or vocal character processing. This is a mix, not a design pass. * **Fixing the recording itself.** De-noise reduces a noise floor; it doesn't remove a passing motorbike, a clipped peak or a room with bad acoustics. * **Renaming or re-classifying a clip.** If a clip is misread as music, say so in words (*"the file called 'ambience' is dialogue"*) rather than expecting a setting. * **Asking for a specific dB number per effect.** Say what you want to hear; the target does the rest. ### Recommended pattern > *"\[Delivery target]. \[Voice/music balance]. \[Known problem to fix]. \[What to leave alone]."* **Example:** > *"Podcast mix for Spotify. Music clearly under the voice, ducked hard on every line. There's a constant hum in my mic — clean it. Don't over-compress, I want the delivery to breathe."* If the first pass isn't right, change **one** thing in the prompt and re-run rather than rewriting the whole instruction — it's much easier to tell what moved. ## After the run The mix arrives as standard Premiere audio effects on your clips — volume, high-pass, compressor, de-noise, de-esser, limiter — plus volume keyframes on the ducked beds. That means you can: * **Adjust anything by hand** in the Effect Controls panel. * **Reshape a duck** by dragging its keyframes. * **Remove a treatment** you disagree with, clip by clip. * **Undo the whole thing** with Cmd/Ctrl+Z. Listen on the monitoring you actually deliver on. A mix anchored at -16 LUFS is correct even if it feels quiet next to a loud reference track in another app. ## Common Pitfalls * **All audio on one track** → clips still get treated individually, but a voice and a music bed sharing a track make classification harder. One source type per track gives the best result. * **A music bed that never ducks** → it probably wasn't read as music. Say what it is in the prompt. * **Nested sequences or multicam** → the audio inside them can't be analysed as separate sources. Flatten first. * **Already-processed clips** → Auto Mix adds its own effects on top of yours. Remove your previous audio effects before running, or the two stack. * **Expecting a repair tool** → de-noise handles a steady noise floor. Clipping, wind blasts and room reverb are recording problems it cannot undo. * **Touching the timeline mid-run** → let it finish; it's reading and writing your sequence. **Recommended workflow:** one source type per audio track → a two-sentence prompt naming your platform and the music/voice balance → full-timeline pass → listen → fix any single section with a Time Start / Time End re-run. # Auto SFX Source: https://docs.premierecopilot.com/features/auto-sfx Analyze your edit, generate matching sound effects with AI, review every suggestion, and place them automatically on the timeline. Auto SFX reads your edit, finds moments that can benefit from sound design, generates matching sound effects, and places them automatically on your timeline. You stay in control: the tool first creates a list of suggestions, then lets you select, reject, or add sounds before anything is generated or placed. Works in **Premiere Pro** and **DaVinci Resolve**. ## Video tutorial Watch the complete Auto SFX workflow, from choosing the analysis settings to reviewing and placing the generated sounds:
