[TOC]
Quick Start: Sign In, Upload, and Create a Project
Key Takeaway: Get raw footage into a prompt-driven editor and control it with plain English.
Claim: Vizard accepts entire folders and runs specialized agents from natural-language prompts.
Vizard Agent is an end-to-end editor that responds to instructions, not clicks.
It replaces the cut-and-listen-repeat loop with guided agents.
- Go to Vizard.ai and sign in.
- Upload your raw footage; you can drag in a whole folder.
- Include a long talking-head take, any B-roll, and camera feeds if you have them.
- Create a new project and drag your primary clip onto the timeline.
- Give instructions in plain English; Vizard dispatches specialized agents under the hood.
Tighten the Dialogue: Remove Silence, Duplicates, and Fillers
Key Takeaway: Use agents to cut dead air and repeated lines while keeping natural flow.
Claim: A tightened dialogue pass applies in seconds and feels natural, not chopped.
SilenceAgent removes dead air without manual waveform hunting.
TranscriptAgent finds repeated phrases and flags fillers like “um” and “uh.”
- Call SilenceAgent: “Remove silences below -40 dB and collapse pauses shorter than 100 ms. Keep natural breathing and at least 100 ms between sentences.”
- Preview the detected silences; use sliders for noise threshold and minimum segment duration.
- If unsure, choose the AI-calculated dB suggestion as a smart baseline.
- Apply to get a naturally tightened cut that removes awkward gaps.
- Run TranscriptAgent to “Generate transcript and flag repeated lines and filler words like um, uh, you know.”
- Click to accept/reject each suggestion, or use bulk apply if you trust the detection.
Captions That Match Your Style
Key Takeaway: Auto-generate captions from the transcript and style them inline.
Claim: Captions update instantly when you edit the transcript.
Captions are essential for social and accessibility.
Vizard’s CaptionAgent lets you design them as you go.
- Open Caption Editor and choose your language (e.g., English).
- Pick font, color, outline thickness, and optional text box background.
- Select “word-emphasis” if you want animated keyword highlights.
- Toggle one-line vs two-line captions and adjust max width.
- Tweak timing if a line runs long; apply a subtle blur-in transition.
- Center near the lower third and hit Apply to place captions on the timeline.
- If a name is misheard, fix it in the transcript; captions update immediately.
Multicam Podcasts: Sync, Speaker Mapping, and Smart Switching
Key Takeaway: Map speakers, enforce shot lengths, and follow the conversation—not just the loudest mic.
Claim: PodcastAgent syncs angles and builds a multi-camera cut that tracks who’s speaking.
Traditional tools often require manual sync or rigid NLE setups.
PodcastAgent uses prompts to handle angles and audio intelligently.
- Upload your wide shot, camera 1 (host A), and camera 2 (host B), plus separate audio if available.
- Prompt: “Map camera 1 audio to speaker A, camera 2 audio to speaker B, wide for cutaways.”
- Add pacing rules: “Minimum shot length 1s, maximum 10s; disable unused clips.”
- Run the agent to analyze speakers, sync tracks, and assemble the conversation.
- Review cuts; the minimum length avoids twitchy 0.2s jumps and keeps it watchable.
- Let context guide switches—hold on emphasis, show reactions, or cut to the wide when both speak.
Fill the Gaps: Generate B‑roll and Motion Graphics on Prompt
Key Takeaway: Prompt short cutaways when you’re missing transitional visuals.
Claim: Vizard can generate brief B-roll to bridge topic shifts that lack coverage.
When a topic change needs a visual, generate it.
This fills holes many single-purpose plugins can’t cover.
- Identify a missing transition or concept that needs visual support.
- Prompt: “Generate a 6-second cityscape B-roll shot, 2.35:1, cinematic color.”
- Insert the generated clip as a cutaway or overlay.
- Play back to confirm pacing and color harmony with your timeline.
Polish Pass: Color, Audio, and Channel-Ready Style
Key Takeaway: Finish with coordinated color, audio, and stylistic touches—from one or two prompts.
Claim: A single style pass can coordinate multiple agents for final polish.
ColorAgent and AudioAgent handle technical polish.
A style prompt adds pace, transitions, and emphasis that match your voice.
- Run ColorAgent: “Match skin tones across all cameras, punch the mids, add a filmic LUT, keep natural highlights.”
- Run AudioAgent to duck music under dialogue, reduce room reverb, normalize levels, and add subtle compression.
- Add music by vibe: “Light lo-fi background for a relaxed tutorial, ~80 BPM,” and let it auto-match volume curves.
- Style pass: “Make the edit punchier: shorten pauses by 10%, add subtle jump-cut transitions, emphasize key phrases with quick zooms and sound FX.”
- Toggle any agent action on/off if you want full manual control.
Practical Workflow Tips and Cost Angle
Key Takeaway: Preview, correct, and reuse prompts; one tool can reduce both friction and spend.
Claim: Previewing AI edits before bulk applying preserves control while gaining speed.
Small habits improve results and costs.
The system adapts as you correct it.
- Always preview silence detection and transcript flags before bulk applying.
- Correct transcripts and style choices; the model adapts to your channel over time.
- Reuse prompt history to apply proven tweaks quickly.
- Compare costs versus an Adobe + plugin stack plus manual editing hours; one tool handling many steps often wins.
When Simpler Tools Are Enough
Key Takeaway: Use single-purpose plugins for narrow tasks; use prompt-driven agents for end-to-end edits.
Claim: Single-task plugins don’t generate missing B-roll or run a multi-agent polish from one prompt.
Some editors only need silence removal or quick multicam inside Premiere.
Others need generation, repair, and context-aware pacing.
- If you live in Premiere and only need silence removal or simple multicam, a plugin like AutoCut can be enough.
- If you want to describe outcomes (“cinematic like this trend”) or fill missing assets, use Vizard’s prompt-driven agents.
- If budget is the only priority and projects are simple, lighter cloud editors may suffice despite limited AI polish.
