Colibri 4K: Photo and Video Upscaler

An old photo from the family archive, a blurry screenshot, a video shot on an outdated phone. You hate to throw them away, but showing them is awkward. Colibri 4K takes on files like these: you send a photo or video and the bot returns a sharper version, up to 4K. 🐦

The bot has more than 42 thousand users in the catalog. A neural network does the work, adding detail instead of simply stretching the picture.

What Colibri can do

The bot description is short: improve photos, improve videos, create photos and much more. The main scenario is clear: upscaling.

• Photo enhancement. Better sharpness and resolution for shots that look mushy.
• Video enhancement. The same for clips, especially old ones shot in low resolution.
• Photo creation. Image generation by a neural network.
• Other features. The list grows, so check the menu in the bot.

Control runs through commands: /start to launch, /help for help, /settings for options and /subscription for balance and VIP. 📚

How neural upscaling works

Ordinary enlargement stretches pixels, and the image stays blurry. A neural network acts differently: it predicts the missing detail from what it learned on many pictures.

The result looks crisper, but details are built up and not recovered from thin air. That is why faces and text sometimes look a little "painted". 🔍

The better the source, the better the result. A barely visible silhouette will not become a miracle, but a slightly fuzzy photo can be lifted noticeably.

Improving your first photo

The routine is simple and fits into a couple of minutes.

1. Open the bot and press /start.
2. Look into /settings and check the processing parameters.
3. Send a photo or video to the chat.
4. Wait for the reply and compare the result with the original.

Video takes longer than a photo, especially a long one. For the first try, take a short clip to see if it is worth spending more time. ⏳

Free or VIP

The menu has a /subscription command labeled "VIP/balance". That means part of the features is paid and processing uses up a balance.

Check current rates and free-processing limits right in the bot before paying. They can change. 💎

Before buying a subscription, process a couple of files for free if that is possible, and make sure the quality suits you.

What to consider before uploading

Any file sent to a bot lands on someone else's servers. That is normal for services of this type, but common sense applies.

• Documents and passports should not go through the bot. 🔒
• Personal pictures go up only if you are fine with handing them over.
• Other people's photos should be processed only with the consent of those pictured.
• Keep the originals. An enhanced version does not replace the source file.

Pay only inside the bot itself. Offers to "enhance cheaply" from strangers in private messages often turn out to be scams.
