Rendering happens in your browser using FFmpeg, which means it's tied to that tab staying open until the render finishes — closing it mid-render stops the job. Combine that with a monthly cap of 60 exported minutes on the Starter plan, and it's clear why checking things once before you hit render beats discovering a problem in the finished file and re-rendering.
The checklist
| Check | What to look for |
|---|---|
| Target length | Confirm you picked 60, 75 or 90 seconds intentionally, not by default |
| Resolution | 1080x1920 or 720x1280 — match it to where the video is going and check the current spec in the app for exact options |
| Orientation | Vertical 9:16 throughout; landscape source clips should already be converted, not left letterboxed |
| Audio setting | Keep or mute chosen deliberately, based on a full-sequence listen |
| Clip order | Hook at the front, peak placed intentionally, payoff at the close |
| Duplicate flags | Any exact-duplicate warnings from import addressed, remembering they don't catch near-duplicate retakes |
| Final preview watch | One full watch-through in preview, not just the first few seconds |
Steps to run through right before rendering
- Do one uninterrupted preview watch
Not a scrub-through — play it start to finish at normal speed the way a viewer would.
- Confirm resolution and orientation settings
These are set at export time and easy to leave on a default that doesn't match your target platform.
- Re-check the audio decision
Make sure the keep/mute choice you made during the audio pass is still the one selected.
- Verify your browser tab and connection are stable
Since rendering runs in-tab via FFmpeg, closing the tab or losing power mid-render stops the job and wastes the attempt.
- Check remaining export minutes for the month
If you're close to the 60-minute cap, prioritize the version you're most confident in rather than testing multiple exports.
Mistakes this checklist catches
- Exporting at 720x1280 out of habit when the destination platform expects 1080x1920.
- Leaving a resolved duplicate warning unaddressed because it was dismissed rather than fixed.
- Rendering with source audio still on after deciding during the audio pass to mute it.
- Starting a render, then closing the laptop lid or switching away from the tab, stopping the job partway through.
- Not knowing how many exported minutes remain for the month before starting a long render.
If the tab closes or the render otherwise stops partway through, it doesn't resume from where it left off — you start that export again. Keep the tab open and the device from sleeping until the render finishes.
After the render finishes
The finished file downloads as an MP4 and also lands on your Exports page, where a render queue shows progress and lets you retry a failed job. Do one final check of the downloaded file itself — open it and confirm audio, orientation and length match what you expected — before you consider the export done and move on to posting it.
