Paid Social Video: Check Captions in Ad Previews

Introduction

A video can look clean in the editing timeline and still be hard to read in an ad preview. The team needs to check how the finished asset appears with the controls and call to action that surround it. This checklist starts once a spoken video has an approved message. It ends with a decision about captions for each selected placement and a named person who can resolve any mismatch.

Use it alongside the imagineInk social media strategy guide when you turn planned short video into paid creative. If the question is which channel should carry the message, start with the organic and paid social guide . Here the channel and placement list already exist, and the reviewer needs to decide whether the viewer can follow the video in that setting.

Gather the final export, approved script or transcript, caption file if there is one, and the placement list. Ask the editor to identify which version each placement receives. Assign someone to review wording and someone to check the rendered ad. Those roles can belong to the same person if they can compare the preview with the source and record what they actually saw.

W3C's guidance on captions explains that captions represent speech and meaningful non-speech audio in text synchronized with the video. Use that principle when checking the script against the export. Include a sound cue if the viewer needs it to understand what happens. Put the essential instruction on screen long enough for the reviewer to read it without pausing. Check the script for what the viewer needs, including names, conditions and the intended next step.

Test each placement in the order the viewer sees it

Start with the current draft preview on a device close to the one you expect people to use. Begin playback at the start. Review the full clip with sound off, then turn the sound on for a timing and wording pass. A still frame helps show where text is covered, while replay shows when it becomes hard to follow.

• 1. Prepare the draft for review. Before you begin, match the video version in the ad draft to the approved export and confirm what should supply the text. Adobe's Premiere export guide describes burned-in captions rendered into the video and separate sidecar exports. If the draft shows repeated text, compare the uploaded video with the caption settings before asking the editor to rewrite the line.
• 2. Open the actual preview. In this step, look for text that sits under a button or within a crop. TikTok's video advertising guide recommends keeping captions in safe zones so controls do not cover them. Check the current placement preview for the platform you plan to use. One screenshot from another placement cannot verify the rest of the list.
• 3. Validate meaning and timing. Compare captions with the speech and essential sound cues. Watch for an omitted restriction, a product name that changes meaning, or text that appears after the scene it describes. Mark the first time in the clip where the reviewer loses the thread.
• 4. Troubleshoot a failure. Replay the same moment in the approved export and the ad preview. If only the preview fails, send the placement and a screenshot to the ad operator. If both fail, send the timestamp and expected line to the editor.
• 5. Record a decision. Save the placement name, preview date, version, timestamp of any issue and the person who owns the fix. If a preview cannot be opened or a setting is unresolved, mark that placement pending until someone can verify it.

Fix the first point where the caption fails

If the caption is wrong in the video file, return the exact line and timestamp to the editor. If the export is clear but the preview hides the bottom line, ask the operator and editor to check the placement crop and the text position. If text appears twice, check which version has captions in the picture and which caption layer is also enabled. Capture the symptom before making changes so the next reviewer can reproduce it.

Suppose an offer qualification is readable in the feed preview but the last line is covered by a button in the vertical preview. Hold the vertical placement. Have the editor move the text or prepare a version that fits there, then reopen the preview and play through that moment again. Give the new export its own version in the paid ad creative handoff record . Carry the earlier pass only for the exact export and placement it covered.

Keep a separate decision for every selected placement

Use a row with the placement, video version, caption source, reviewed device, defect timestamp, evidence and next owner. Mark ready when a reviewer can read the full intended message and the captions align with the relevant audio. Mark hold when a known defect makes the text difficult to read or changes its meaning. Mark pending when the preview or another required input is missing.

Retest after a caption, placement or video version changes. If a different person is releasing the ad, give them the reviewed row and point to the draft it represents. They should be able to tell which preview was inspected without reopening the editing project. That makes the record useful for launch even when one placement needs another revision.

Sources and how to use them

These references cover caption meaning, export behavior and placement guidance. Use the accessibility guidance to judge the text against the audio, the editor's documentation to identify the caption source, and the placement guide to check what can cover a line. Confirm the version your own review will use.
