Screen Recording to Polished Video for demos customers and prospects can follow
Start with the real product take, then remove dead time and clarify what is happening on screen. Add captions, callouts, narration, and brand, then prepare sales, support, or launch edits separately.
Upload the real walkthrough, tell ngram how to handle its speech, and identify the steps that need explanation. Review the plan before creating the polished video.
01
Drop the recording in
Upload an MP4, MOV, WebM, MKV, or AVI recording. ngram transcribes the narration and uses the recording as the source for the walkthrough.
02
The agent reads the capture
ngram inspects the recording and proposes a plan around the useful actions. Specify whether to keep, clean up, replace or mute the original speech, and name the moments that need step labels, callouts or diagrams.
03
Steer the cut in plain language
Ask for a shorter opening, a clearer step label, or a graphic that explains the result before returning to the recording. Select your Brand Kit and choose any saved intro or outro slides you want to include.
04
Review and export the video
Review the screen recording video for its intended channel, including the crop and caption placement, then export one MP4 from Studio. Prepare and review another aspect ratio as a separate edit.
Output controls
Real knobs for cleaning up a raw screen capture.
Dead-air auto-trim
Silences, loading spinners, and ‘where was that tab’ moments are detected and cut. Adjustable threshold per recording: keep the breaths, kill the limbo.
Smart zoom on click
Cursor and click moments become push-ins on the affected UI region. Each zoom is editable: pick a different target, change the hold time, or remove it.
Cursor smoothing and click emphasis
Jittery trackpad paths are eased; clicks get a subtle ripple so viewers see the action without you narrating ‘and now I click here’.
Burned-in captions from your narration
Caption track generated from the recording’s audio, styled by your brand kit, and burned into the export. Edit any line in the script panel.
Branded backgrounds and frames
Wrap the recording in a branded frame, drop in a background gradient, or add a logo bug, applied per workspace brand kit at /app/brand-kit.
Prepare each channel edit separately
Set the intended channel and aspect ratio for the screen recording video, then review the crop, caption placement, and CTA before exporting one MP4. Prepare another channel version as a separate edit.
Section cards and chapter labels
The agent proposes section titles based on what the screen is showing. Edit the wording, change the duration, or skip them per chapter.
Security questions, answered by our team
Recordings stay in your workspace, and you can delete them anytime. Talk to sales about security, access controls, and data handling for your team.
Triggers, not screenshots. Wire screen recording to video into the tools you already use.
Every integration ships with a working recipe tuned for the screen-recording workflow. Start from one, or wire your own with the REST API and self-managed webhook subscriptions for video.completed or video.failed.

How it compares
If you’ve been polishing recordings somewhere else.
Loom handles the capture, Descript and Camtasia handle the timeline. ngram reads the recording, builds the plan, and turns the source into a reviewed channel-specific edit and one MP4 export, so the polish step stops being a project.

API + webhooks for the workflow

Upload MP4, MOV, WebM, MKV, or AVI files from Loom, OBS, QuickTime, ScreenPal, or a native recorder. You can also record in the browser, then use that recording as the source for the walkthrough.
How long can the screen recording be?
Files up to 500 MB upload on the starter tier and around 5 GB on paid. Recordings between 30 seconds and 30 minutes are the sweet spot. Longer captures process; they just take longer to render and benefit from the dead-air trim more.
Will the captions match the original narration?
Yes. AssemblyAI transcribes the recording, the agent aligns each line to the on-screen action, and the captions are styled per your brand kit. Every caption line is editable in the script panel before export.
How does the smart zoom work on a screen recording?
The agent reads cursor paths and click moments, then proposes a zoom target on the affected UI region. You see each zoom in the storyboard before render, so you can change the target, change the hold time, or remove it per scene.
Can I get landscape, square, and vertical from one screen recording?
Prepare and review each aspect ratio as a separate screen recording video edit. Check the crop and caption placement for that channel, then export one MP4 from Studio.
Does my brand kit apply to a Loom export?
Set up your Brand Kit at /app/brand-kit, then select it when creating the video to use its logo, colors, fonts, and motion style. Choose saved intro and outro designs if you want to include them. Turn on captions whenever you want.
How long does the polish take?
Render time varies with the source length, format, and requested changes. You can review and edit the script, scenes, captions, and timing in the agentic workflow before exporting the finished video.
What about privacy, where do recordings go?
Your recordings stay in your workspace, and you can delete them whenever you want. For security, access controls, and data handling specifics for your team, talk to sales.
Can I localize the polished walkthrough?
Yes. The same recording can be re-rendered with translated captions, on-screen text, and an optional voiceover dub in the target language, driven by ngram’s translation feature.
Is there an API for this?
Upload the recording in Studio and review the generated video there. The Public API accepts documented text or URL inputs, not the recording file as a direct upload. Public webhook subscriptions emit video.completed or video.failed for supported API jobs.
Can I add explanations while keeping the original presenter audio?
Yes. Ask ngram to retain the original speech and add labels, callouts or short graphic inserts at the points you name. Review the transitions back to the recording so the visuals still match the explanation. Ask for clean footage when you want a passage without overlays.
