Topaz Astra in the Syntx AI neural network: why do you need a tool to improve video quality
Zand over the past two years, the AI content market has changed beyond recognition. Almost any modern neural network generator can create images, animations and videos based on a text request. Dozens of services have emerged offering free AI video generators, hundreds of character creation tools, and thousands of tutorials on how to make your own AI cartoon in one evening.
NBut there is one problem that is rarely mentioned in advertising reviews.
BMost generators do a great job of creating an idea. But the final picture quality often leaves much to be desired. Especially when it comes to long videos, complex scenes, camera movement, or close-ups of characters. That is why professional creators have long divided the process into two stages. First, the neural network works to generate the video, and then a separate tool takes care of the final polishing of the result.
It was for this task that Sinteks created the Topaz Astra.
EIf earlier classic upscalers simply increased the resolution of the video, then Astra works much deeper. It analyzes the contents of each frame, finds generation artifacts, improves detail and is able to accurately fill in missing image elements. As a result, the video becomes clearer, smoother and visually richer.
OhThis is especially noticeable in AI content. When a typical generated video looks a little plasticky, Astra helps restore volume to textures and give characters a more natural appearance.
PIn essence, Topaz Astra can be called the final stage of content production within the Syntx aggregator. The same step that separates the draft from the finished result.

How to use Topaz Astra in the Syntx aggregator and which setting to choose
RWorking with the tool starts as simply as possible.
B in the main menu you need to open the “Tool kit” section and select Topaz Astra.
PAfter this, you can download the video in two ways. Either drag the file directly into the upload window, or select a video from those that have already been created or uploaded previously within the platform.
And This is where the fun begins. After loading, a menu of processing modes appears on the right. At first glance, it may seem that the differences between them are insignificant. In practice, it is the choice of mode that determines the final result.
Creative - when a neural network can radically change a video
RCreative mode works like an artist who was given a sketch and asked to make it beautiful.
OhIt doesn't just improve existing parts. He actively draws new elements, enhances textures, adds depth to scenes and makes the image visually richer.
EWhether you're creating an AI cartoon, an animated series, fantasy scenes, or stylized content, this mode can literally breathe new life into your video. It is on such projects that its capabilities are revealed to the fullest.
However, there is a nuance.
Creative sometimes starts to take too much initiative. If there is a realistic person in the video, the mode can subtly change the appearance, add unexpected details, or interpret the scene in its own way. Therefore, it should be used carefully for realistic videos.
Precise 2.5 - a universal choice for most tasks
EIf the Topaz Astra were a car, then the Precise 2.5 would turn out to be the most reliable car that is recommended to friends without much hesitation.
EThis mode treats the source material as carefully as possible. His task is not to invent something new, but to improve what already exists.
AndThis is why Precise 2.5 is great for bloggers, commercials, interviews, video presentations and most AI videos with people. It makes the image noticeably cleaner, but maintains the original structure of the scene.
PAccording to the test results, it is this mode that shows the most stable results on almost any type of content. RThe results of the experiments will be compared below. First, let's talk about setting up the remaining parameters.
Precise and Fast: when speed and budget matter
RPrecise mode can be called the younger brother of version 2.5. It works on the same principle, but uses less modern processing algorithms.
Fast, as the name suggests, it relies on speed. The quality here is slightly inferior to the higher modes, but the videos are processed much faster and are cheaper.
EIf you need to quickly test multiple versions of a video or prepare drafts for a client, Fast becomes a reasonable choice.
How to improve online video for free using a neural network: detail, smoothness and resolution settings
PAfter selecting the mode, the most interesting part begins - setting the processing parameters. This is where you decide how much to change the original video.
Pfirst parameter - permission.
Topaz Astra allows you to increase the quality of the video up to Full HD and 4K. For most tasks, 1080p is sufficient. This resolution already looks great on social networks, YouTube and advertising accounts.
With 4K the situation is a little more interesting. It is logical to assume that higher resolution automatically means better results. But in the case of AI content, this does not always work. Sometimes ultra-high detail begins to show generation features too clearly, especially when we are talking about cartoons or stylized videos.
Cnext parameter - frame rate.
PIncreasing FPS makes movements smoother and more natural. The effect is especially noticeable in dynamic scenes, camera passes and character animation.
Ohthe function deserves special attention Slow Motion.
MMany creators use it to create eye-catching commercials. Instead of the usual slowdown, Astra recalculates the movement of frames and makes it smooth. This makes the video look cinematic rather than randomly drawn out.
Pthe last parameter is Creativity. This is a kind of regulator of the model’s fantasy. At low values, Astra practically does not interfere with the content of the frame. At high levels, he begins to actively draw in details and stylize the image.
DFor realistic videos, like the girl in our example, it is better to stick to moderate settings. For animation and creative projects, like with a cartoon about a cat, you can allow the model more freedom.
Dlet's do it. Let's compare two settings options on different video formats. First, we test the modes on a realistic commercial with a girl. And then - on a cartoon and let's see how Topaz works with animation and a cartoon character.
ZLet's set the settings for realistic video in Presize 2.5 mode:
And here are the settings for Creative mode:
TNow let's move on to the AI cartoon. Setting up Presize 2.5 mode:
TNow let's set up Creative:
Bwhat happened. From top to bottom, the frames are arranged in the following sequence: source - presize 2.5 mode - creative mode. Creative made the cartoon character smoother and softer. On the contrary, he detailed the person’s natural face so that she had bruises under her eyes and some spots of unshaded foundation. Whereas Presize 2.5 barely noticeably worked on the texture and color correction of the face, like a professional retoucher.
Unlike the example with the girl, it didn’t get any worse here. The 4k quality emphasized the neural network origin of the video, but for a cartoon this is never a bad thing.
Why Topaz Astra is becoming a must-have tool for AI video creators
EIf you look at the market of modern profitable aggregators, it becomes obvious that users have long been looking for more than just generation tools. Content makers want to get a full cycle of work within one platform:
CI started to come up with an idea.
PThen create images.
Zthen make a video.
PAfter this, improve the result and prepare it for publication.
AndThis is why solutions like the Syntx aggregator are gradually becoming a work center for content creators. There are already dozens of models for generating images and videos, and now there is also a tool for professional post-processing.
FIn fact, the user gets the opportunity to go all the way within one ecosystem. From the first prom to the final video. This is precisely the main meaning of Topaz Astra.
Eit’s not just another fancy feature for the sake of a nice tick on the list of features. This is a tool that helps bring AI content to a level where you actually want to publish it. And in a world where new neural networks for video generation appear every day, it is the quality of the final result that is increasingly becoming the main competitive advantage.
