Many years ago I made video distribution amplifiers. I used video amp ICs, not opamps.
Most semiconductor manufacturers have video amp ICs.
I made my video amps about 16 years ago. The ICs were made by Motorola. They aren't made anymore. The ICs were inexpensive.
I don't know what is available in your country. Ask somebody in your country.

I think, nowadays what is commonly available there will be like that here also. Right?
Not that I've seen. I can get parts from several sources, digikey has almost everything. Does India have a digikey equivalent?
Video ICs are usually triple (R,G and B) and can drive 150 ohms (75 ohms sending then 75 ohms receiving.
Opamps are usually dual or quad and drive 2k ohms.
Video ICs usually have the gain setting resistors built-in.
Try it. Digi-Key Corporation - USA Home Page compare prices and the site has a huge inventory.
Since most users of video amps have historically been using RGB, that's the most common (and therefore most available and usually cheapest) product.Here I don't need RGB output.
