Before you trust an AI video review, check what it can see
AI can analyze video, but a video link does not tell you what the system actually received. It may get a speech transcript, selected images, or video and audio. Check the input first, verify a few timestamped observations yourself, and treat performance explanations as hypotheses unless you have the relevant analytics. Even a model that sees the footage cannot read viewers’ minds or prove why they left.
01 · BEFORE THE REVIEW
Check what reached the AI
You paste a video link and get a detailed critique of its hook. Before changing the edit, find out what the application passed to the model. The link might have been converted into subtitles. It might have supplied selected frames, the video itself, or no accessible content at all. A fluent answer does not settle that question.
Start with the application’s upload or import documentation and the visible source preview. If you built the workflow, inspect its actual request or extracted files. Asking “Did you watch the video?” can reveal an admission of missing access, but the model’s own assurance is not proof that it received or inspected the footage.
Product names alone are insufficient. Google’s notebook YouTube-import documentation says that only the video’s text transcript is imported. The Gemini API separately supports video and audio understanding. Those are different input paths, even though both come from Google.

Similarly, Claude’s file-upload documentation lists supported documents and images, including JPEG, PNG, GIF, and WebP. It does not list ordinary video files among those uploads. That does not mean Claude cannot see images, or that a separate tool cannot supply video frames. Check the specific application and workflow you are using before deciding what its review can support.
02 · ASK AN ANSWERABLE QUESTION
Match your question to the evidence
A speech transcript can be useful for tightening a spoken promise. It cannot establish whether the viewer sees the promised result while that line is being spoken. Choose the question after checking the input, and add the missing material when the question requires it.
| Input available | Useful review | Still missing | Next action |
|---|---|---|---|
| Speech transcript | Spoken promise, explanation order, repeated lines | Visual proof, delivery, music, unspoken text | Add opening frames or supported video input |
| Timestamped still frames | Visible objects, layout, readable text at those moments | Between-frame changes, continuous motion, sound | Supply the relevant interval and audio if needed |
| Video and audio | Observable sequence, delivery, caption and speech alignment | Potentially missed details; private audience response | Verify the cited moments against the original |
| Generated visual description | Reasoning about the events that description records | Anything its first analysis omitted or misread | Check important descriptions against the footage |
| Video plus owner analytics | Compare reported viewing patterns with events in the cut | Why individual viewers reacted; controlled causal evidence | Keep metric definitions and test one editing hypothesis |
“Transcript” can also mean more than speech. Cloudinary describes visual transcription as descriptions of what happens on screen. That text can carry visual evidence into a later review, but it remains a generated account of the video. Ask whether your text contains spoken words, visual descriptions, or both.

Constructed example: one spoken line, two different openings
Imagine two clips saying, “This is why your desk still looks messy.” In Cut A, the speaker faces the camera against a blank wall. In Cut B, an overhead shot reveals a tangled cable pile as those same words play. A speech-only transcript is identical for both. It cannot tell you that Cut B makes the problem visible immediately.
The useful next step is to inspect the opening shot before rewriting the line. You could test whether showing the cable pile makes the promise easier to understand. This invented example demonstrates an information gap. It provides no evidence that either cut would get better retention or more views.
03 · COVERAGE IS NOT GUARANTEED
Why seeing frames still leaves gaps
Receiving a video does not guarantee that every detail survives processing. Google’s Gemini API documentation describes a default one-frame-per-second rate for static video processing, with configurable sampling. It also describes adaptive, agentic video processing for supported models. Do not apply one default to every model, application, or Kabo workflow.

A brief title card can fall between sampled frames. Small text can become hard to read after resizing. A still may show a hand near an object without showing which movement happened first. The right response to a questionable observation is to check the original interval, not to ask for a more confident explanation.
For a caption problem, provide a legible frame and check the wording yourself. For a cut or movement problem, supply the surrounding interval through a supported video path. For delivery or music, confirm that audio is included. A timestamp makes a claim easier to inspect, but a generated timestamp is not evidence that the claim is correct.
04 · OBSERVATION BEFORE EXPLANATION
A confident explanation is not a measured cause
“The result appears after the introduction” is an observation you can verify in the cut. “Try showing it earlier” is an editing hypothesis. “Viewers left because the result came too late” is a causal explanation requiring evidence the video alone does not contain.
YouTube’s audience-retention report is available at the video level in Analytics. Its guidance says dips can indicate viewers skipping a section or stopping their viewing. Even with that report, a dip aligned with a scene change does not establish why people left. Preserve the exact metric, time window, and comparison before connecting it to a proposed edit.
YouTube: key moments for audience retention
Use a review to find inspectable issues, such as these observable opening patterns. If the question is why the same file performed differently twice, compare two uploads using their measurement and distribution context. An analysis of an unchanged file cannot explain that difference on its own.
05 · CHECK YOUR OWN WORKFLOW
Try a controlled input check on one clip
You do not need to rank every model to decide whether a review is useful for your edit. Use a clip you know well and compare the evidence each input makes available. This is a proposed checking method, not a report of a model experiment we have run.
- 01
Write the answer key first
Watch the original. Record the opening words, one detail visible but never spoken, and one audio or timing detail, with timestamps. Keep those notes out of the prompts.
- 02
Separate the inputs
In a fresh conversation, provide only the speech transcript. In another, provide timestamped frames or the video through a supported path. Use the same model and settings where possible. Record any differences you cannot control.
- 03
Ask the same questions
Ask what the opening promises, what visible evidence supports it, and what remains unknown. Require the source for each observation. Do not give one conversation the other’s answer or reveal the answer key.
- 04
Verify before acting
Check each claim against your notes and the original. Mark it correct, unsupported or wrong, or explicitly unknown. An honest “unknown” is useful when the required input is absent. Save the inputs and outputs so you can inspect the comparison later.
If the video-assisted review identifies a real visual detail, that supports only that observation in that run. One clip does not establish a general accuracy rate, and a better description does not prove that the suggested edit will improve performance. If a result is surprising, repeat the check before relying on it.
06 · A REVIEW YOU CAN CHECK
What Kabo’s video analyzer can review
Kabo’s AI Video Analyzer accepts a public TikTok, Instagram Reel, or YouTube Short link. Its current analysis path supplies video media to a video-capable model, so it can review observable visuals and audio rather than relying solely on a speech transcript. Use its timestamped observations to inspect the opening, captions, pacing, and payoff against the original clip.
That input path is not a guarantee that every frame or word was read correctly. The public-link tool does not retrieve your private retention or traffic-source reports. It cannot prove why viewers left or predict the reach of your next cut. If your draft is not public, use the manual input check above with an application that supports the material you can provide.
07 · KEEP THE LIMITS IN THE ANSWER
Use this evidence-first review prompt
Select the complete prompt below and paste it alongside the material your chosen application supports. It asks the model to show its basis for a recommendation. You still need to verify that basis yourself.
Review this clip using only the material available in this conversation. INPUT CHECK List the supplied material: speech transcript, images with timestamps, video, audio, generated visual description, or analytics. Distinguish what you received from what you can verify you inspected. If access or coverage is uncertain, say so. Do not infer access from a URL. OBSERVATIONS Describe the opening, the first visible proof, and one possible pacing issue. For each observation, name the evidence and its timestamp, if available. Do not invent timestamps. Mark visual or audio details unknown when the relevant input is missing. Treat generated descriptions as secondary evidence. INTERPRETATION Separate observed facts, editing hypotheses, and unknowns. Do not invent retention, traffic sources, audience reactions, or causes. If I supply analytics, preserve the metric name and measurement window. NEXT ACTION Suggest one edit worth testing and explain the observation behind it. Name one additional input or manual check that could change your advice.
Keep a recommendation only when you can identify the observation behind it. If the answer invents a visual detail or an audience reaction, remove that claim from your editing notes and obtain the missing evidence before deciding what to change.
08 · SOURCES AND METHOD
Sources and method
The five primary sources below document specific input paths, video processing, visual transcription, and YouTube retention. They were checked on September 16, 2026. Product capabilities and import behavior can change, so recheck the documentation for the workflow you use.
The evidence map, two-cut example, input-check procedure, and prompt are Kabo editorial synthesis. The example is constructed; no comparative model experiment or performance test was run for this guide. Kabo’s input-path description was checked against its current implementation, not an end-to-end inference run. None of these materials establishes a retention improvement.
