Frequently Asked Questions

What it does

Reframes a video from one aspect ratio to another โ€” 16:9 to 9:16, 1:1, 4:5, or custom โ€” with three fill modes (letterbox, blurred background, crop-to-fill). Browser ffmpeg means no upload and no watermark. Useful for repurposing a YouTube long-form into a Short, or for adapting a horizontal ad spot to vertical placements.

Why creators use it

A standalone utility is the right shape for one notch in a creator's workflow. You don't open the full VideoCue app to do this one small thing; you bookmark the tool, paste your input, and move on. That's the bet: tools that respect your time get used. Tools that demand a signup get ignored.

This particular utility is built for the moment you need it: fast in, fast out, no watermark, no upsell. It's a free notch in the larger VideoCue ecosystem โ€” built by editors for editors, kept genuinely lightweight, and stable enough to belong in your daily workflow.

How it fits the workflow

Pre-production tools establish the visual world (mood boards, character sheets, style guides). Writing tools shape the language (word counters, voiceover estimators). Compose tools format the package (aspect, chapters, metadata). Each is small. None pretends to be a full editing suite. Their power emerges when they snap together โ€” your mood board palette flows into your image prompts, your shot list mirrors your storyboard, your transcript translates into your second-language SRT.

This tool is one of those snap-points. Use it on its own when that's enough. Use it next to its siblings when the project demands more. Either way, it costs nothing and waits on no signup.

When to graduate to the paid VideoCue app

The free tools are utilities. The paid app is an end-to-end AI video studio โ€” script, voice, footage, render, publish โ€” that uses the same vocabulary as these tools but ties them into a single project surface. If you find yourself stringing five tools together for every video, you're ready to try the full app.
