Motionix / Your workspace
Give your words room to be seen.
Preview a caption or logo box against margins you control. See where the box overlaps the selected exclusion areas, then check the real platform before publishing.
Starter overlays are illustrations, not official platform specifications. Organic posts, ads, captions, devices and interface updates can have different occupied areas.
Three steps. One result to inspect.
Choose a frame
Open an authorised local image or video. Keep its real proportions; a portrait frame and a landscape frame need different layouts.
Set margins and place text
Adjust exclusions and the text box. The report measures those selected boundaries, not every possible platform interface.
Export and verify
Save an annotated reference frame or settings, then check the actual app/advertising preview. This does not render a finished edited video.
Check whether text fits inside your chosen safe area
The overlay separates your usable region from excluded margins. Move or resize the text box and inspect whether it crosses those boundaries. The mathematical result is useful only for the margins you selected. It does not predict every caption expansion, button position or device crop. Keep important text comfortably inside the reviewed area rather than treating a one-pixel clearance as a universal guarantee.
Why text can be cut off on Reels, Shorts or TikTok
A platform can add controls, descriptions and other overlays, or display the same asset differently across placements. Long captions can occupy more space than short ones. Check the current app and the exact advertising or organic format you plan to use. The starter settings are intentionally editable rather than presented as official fixed pixel rules. This checker does not guarantee views, retention, or accessibility compliance.
An advertising template is not every organic interface
Official advertising specifications can provide placement-specific guidance and downloadable templates. Their scope matters: a TikTok in-feed ad, an organic post and another platform are not interchangeable. Follow the current instructions for your placement and document any custom margins you choose. Do not claim that a sample preset on this page certifies a campaign or reproduces the latest interface on every phone.
Export an annotated frame, then finish the video separately
A preview PNG helps share layout notes without re-encoding an entire video. It is not the final edited clip. Keep the original, retain the settings report, and review readability and contrast as separate decisions. If subtitles need timing changes, repair that file first; if the finished video needs a smaller size, use the compressor afterward. No file upload is required for this local preview workflow.
Your files, with explicit choices
File processing does not require an upload. The site and processing assets use the network. Results are not automatically backed up. Download your result and keep the original.
Frequently asked questions
Does an inside-area result guarantee a safe post?
No. It describes a box relative to your chosen margins. Real platform controls and devices may differ.
Are starter layouts official platform specifications?
No. They are editable starting points. Check current guidance and the actual placement before publishing.
Are advertising and organic video overlays identical?
No. Buttons, captions and placement formats vary. Do not assume that an ad template applies to an organic post.
Does this re-encode my whole video?
No. It previews overlays and exports an annotated frame or settings report. It is not a finished-video editor.
Can I check a still image?
Yes, using supported local images. Keep the original aspect ratio in mind and inspect the destination's own preview.
