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:
- Pulls recent channel posts via API
- Assembles a script with scrolling
- Sets up the avatar, name, and subscriber count
- 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.
