Can an AI agent turn an existing video into a more polished YouTube upload? I tested NoteGPT by giving its agent a running watch comparison and asking it to make professional versions with more on screen information. The process took a few hours, but it produced several versions to review. Here is how the workflow went, what it cost in credits, and what I would check before using the results.

What NoteGPT’s AI agent can do
NoteGPT’s AI agent is designed to carry out a task from a written instruction, rather than simply answer a question. You describe the result you want, and the agent can plan a series of actions, analyse your uploaded material and work through those actions. In this test, I used it to edit an existing video into more engaging YouTube content.
The original video compared a Samsung watch and a Pixel watch during a run. I wanted the edited version to explain the comparison more clearly with text and visual callouts, while still feeling suitable for YouTube. Rather than manually adding every label and animation, I gave the agent the goal and let it decide how to approach the edit.
That distinction matters. An AI agent is not just a video filter that applies the same treatment to every clip. It may inspect the source, make a plan, ask questions when it needs direction, and then perform tasks in the background. The amount of control and the final result can depend on your instructions, the model selected and the tools available to the agent.
Quick answer: NoteGPT’s agent created four video versions and one image from my source video. The task took about two hours and forty minutes and used 105 credits. The result added useful information on screen, but I would still review the edit and compare its performance with the original.

Before you start: upload, models and credits
To begin, open the AI agent in NoteGPT and upload the video you want it to work on. My source was already created, so I opened the file and added it to the agent. Allow time for the upload to finish before writing your request. A large video can take a little while to process, and the agent needs access to the source before it can begin analysing it.
NoteGPT offers a choice of AI models. In my session, the selector included options such as GPT, Claude, Gemini and DeepSeek, as well as Kimi K3, GLM 5.2 and Minimax. The available options and credit costs can change, so check the current interface rather than assuming that every model will cost the same amount.
I left the model on Auto for this test. That gave NoteGPT the flexibility to choose how to handle the task. Selecting a particular model can be useful when you have a reason to prefer one, but the agent may use different amounts of credits depending on the model and the work involved. A more complex task can also require more processing than a simple request.
Before submitting a job, check your remaining balance in the side panel. In my account, the panel showed 1,000 credits before the task. You can use that figure as a reference, but do not treat an early estimate as a guaranteed final cost. NoteGPT displayed an estimated amount while planning, and the usage accumulated as it worked.

Give the agent a clear brief
I started with a direct instruction: create a professional looking video with text, with the goal of increasing viewership and engagement. That gives the agent a useful direction, but it does not specify every editing choice. For example, it does not say which format to create, whether to add music, or how long the finished videos should be.
That is where a simple request can turn into a conversation. The agent analysed the video and asked for more information about the format and the engagement elements I wanted. This is helpful because a video intended for a standard YouTube upload has different framing needs from a vertical short. Asking follow up questions also gives you a chance to make a choice before the agent spends time creating the output.
For a first attempt, try to include the most important details in your opening prompt. You might specify the intended platform, audience, format and editing style. For example:
Please edit this running watch comparison for YouTube. Keep the main footage and make the differences between the two watches easy to understand. Add concise on screen labels, an opening hook and animated callouts for the key results. Create a landscape version for a full video and a vertical version for a short. Keep the tone clear and informative. Do not add background music.
This kind of brief is not a guarantee that the agent will follow every instruction perfectly. It does, however, give it a better starting point than a broad request for a professional video. You can also give the agent room to ask questions when an important detail is missing.
Choose formats and engagement elements
The agent asked which platform format I wanted. I selected both a landscape long format and a vertical short format so I could compare the different outputs. Creating multiple formats can be useful if you publish across more than one YouTube format, but it may increase the amount of work and the number of credits used.
It also asked which engagement elements to add. Background music was already present in the source, so I chose not to add more. I considered captions, an opening hook and a branded introduction, then focused on animated callouts and a subscribe or follow prompt. The agent also asked about length. I chose to create versions at the same length as the original as well as shorter options.
When answering these questions, think about what genuinely improves the video. A callout can draw attention to a useful result, while too many labels can make a clip feel busy. A subscribe prompt may suit a channel video, but it can distract from a very short demonstration. The goal is not to select every available feature. It is to choose the elements that help a viewer understand why the video is worth watching.

What happens while the agent works
After I confirmed the choices, NoteGPT planned the job and began carrying it out. The interface showed steps as the agent moved through the work. It analysed frames from the source and used image analysis tools to inspect them. At one point, the agent indicated that it could not view images directly and then tried another way to examine the material.
This is one of the useful parts of an agent based workflow. It can attempt a different approach when its first method is not enough to complete a task. That does not mean it will always recover successfully or produce the result you want. It does mean the process can involve more than one action, which is why a complex video job may take much longer than a quick chat response.
The agent may also pause to ask you for a decision. When that happens, read the options before continuing. Your answer can change the format, length or content of the final files, and producing both short and full length versions may require more processing than producing only one.
You do not need to keep the agent window open for the whole process. I accidentally returned to the home screen, then went back to the AI agent and resumed the task. It was still running in the background. If you leave the screen, look for the active task or previous agent conversation rather than starting the same job again.
While it was working, the credit display showed activity and the estimated usage changed. I saw a small number during an early step, but that was not the final total for the whole video task. Keep an eye on the overall balance if you are managing a limited number of credits. The final amount is more useful for judging what the completed job cost.

How long did the edit take, and what did it produce?
The job took much longer than I expected. After about twenty minutes, it was still running. I left it to continue, and when it appeared to have stalled, I checked again the following day. It eventually finished in approximately two hours, forty minutes and fifty seconds.
That is a long wait for a video edit, so plan accordingly. The time may reflect the source material, the number of outputs requested, the agent’s analysis and the work required to create the versions. Your experience may be different. A shorter source or simpler request could take less time, while a more demanding job may take longer.
The completed job produced four videos and one image. The videos included two short versions in different aspect ratios and two full videos in different aspect ratios. The agent used 105 credits in total. For this particular test, I thought that was reasonable given the number of outputs, although the cost is something to check against your own account and the current credit rules.
I had previously tested other models and found that one used substantially more credits than Auto. That is a good reason to test a new workflow with a small or straightforward task before using it for a large batch of content. If credit use matters to you, note the model, task instructions, number of outputs and final balance each time. Those details make later comparisons more useful.

Reviewing the final videos
I opened one of the full versions to check the result. It included pop up text with additional information and a verdict at the end. Overall, I thought the extra text made the video more informative than the original. It gave viewers more context without requiring me to add each element manually.
That is a useful starting point, but it does not mean the finished edit is ready to publish without review. Watch every version from beginning to end. Check that the text is accurate, easy to read and on screen for long enough. Make sure a callout points to the right moment, the ending makes sense, and the crop does not cut off important footage in a vertical version.
It is also worth checking whether the edit preserves the original meaning. A short summary or animated statistic can be helpful, but a video comparing products should not imply that a result is more certain than the footage supports. If the agent adds wording that changes the meaning, adjust it before publishing.
My impression was that the result was better than having no extra information, especially for viewers who might not immediately understand what the watch comparison showed. Still, quality is partly subjective. The best way to judge whether the edit helps your channel is to compare it with the original under fair conditions.

A practical way to compare performance
I plan to upload one version without the added text and another with the agent’s text and callouts. Comparing them can help answer a more useful question than whether the edit looks polished: does it make viewers more likely to watch and engage?
For a fair comparison, keep the title, thumbnail, description and publishing conditions as consistent as you can. If you change several things at once, it becomes difficult to tell whether the edit influenced the result. If you publish both versions publicly, consider whether duplicate content is suitable for your channel. You could instead compare the versions privately or test them at different times, while recognising that audience behaviour and timing can affect results.
Look at more than the view count. Depending on the information available in your channel analytics, compare average view duration, audience retention, likes, comments and the point where viewers leave. A version with more views is not automatically a better edit if people stop watching sooner. The goal is to learn whether the extra information helps the intended audience stay interested and understand the content.
- Keep a copy of the original. You will need it as a reference and may want to return to it.
- Review each output. Check the full video and short versions separately because their framing and pacing may differ.
- Record the settings. Note the model, prompt, requested formats and credit use.
- Compare relevant results. Use audience retention and engagement as well as total views.
- Make one change at a time. That gives you a clearer idea of what helped.

What I would improve in the workflow
The first improvement would be to make the prompt more specific before starting. My initial request described a professional video and a goal of increasing engagement. The follow up questions helped, but I could have saved some back and forth by stating the preferred format, length, music choice and on screen elements at the beginning.
The second improvement would be to start with one output format. Asking for both short and full versions in different aspect ratios is useful when you want several assets, but it also expands the job. If you are trying NoteGPT for the first time, begin with one version and inspect the quality. If that works well, ask for additional formats in a later task.
Finally, I would set realistic expectations for timing. The agent ran in the background, which made it possible to leave and return later, but the two hour wait was still significant. Do not rely on a complex edit being ready immediately before a planned upload. Start the task early enough to review the files and make manual corrections if required.

Quick checklist before publishing
- Confirm that the correct source video was uploaded.
- Check that the chosen aspect ratio suits the destination.
- Watch for inaccurate text, labels or statistics.
- Review pacing, cropping, audio and the final call to action.
- Save the original and the edited versions separately.
- Check credit use in your NoteGPT account after the task finishes.
- Compare audience response without assuming that more visual effects always mean better engagement.
