How we made a demo video for the popular Telegram channel Droidergram — post scrolling, mobile interface, and automatic generation by username

Droidergram Case: Channel Promo Video in a Few Clicks

Soberi Demku isn't just for bots. One of the most requested scenarios is promo videos for Telegram channels. And Droidergram is a great example.

Droidergram is a popular channel about technology, gadgets, and the Android world. Thousands of subscribers, regular posts with photos and videos. How do you show all this content to a potential subscriber in 15 seconds?

The "Telegram Channel Demo" Template

For channels, we have a special template — Telegram channel demo. Just enter the channel's username (e.g., droidergram), and the system automatically:

  1. Pulls recent channel posts via API
  2. Assembles a script with scrolling
  3. Sets up the avatar, name, and subscriber count
  4. Generates the finished video

For Droidergram, we used exactly this approach — and got a ready demo in a few minutes.

How It Works

Post scroll. Recent channel posts are loaded and shown via fast scrolling. The viewer sees a content stream — photos, text, formatting style. No need to read every post — just grasp the vibe.

Mobile interface. The video looks like a phone screen — exactly how most people read Telegram channels.

Channel interface. Chat type "channel" — shows the name and subscriber count without an input field. Looks exactly like real Telegram.

Why Channels Need Demo Videos

Telegram channels compete for subscribers. A text description is boring. But a 15-second video where the viewer scrolls through a feed of real posts — that's instant immersion.

A channel demo video can be used:

  • In ads — targeted posts in other channels
  • In Instagram Reels / YouTube Shorts — to attract audience from other platforms
  • In channel catalogs — video previews stand out among text descriptions
  • On a landing page — if the channel has its own website

Two Ways to Create a Channel Demo

Automatic — via the Telegram channel demo template. Enter the username — get a video. Great for quick results.

Manual — via the editor. Full control: choose which posts to show, configure scrolling, add music and transitions. Best when you want to showcase only the best posts.

Both options are free for your first video.
