How I stopped juggling 5 AI video subscriptions (My experience with OpenGen ai)

Hey IH 👋

Quick one for anyone who makes their own marketing assets as a solo founder.

The problem

I'm building a SaaS product related to outreach automation, and for our launch on Product Hunt I needed a few short video clips: a hero video for the landing page, a couple of vertical clips for social, and some product-shot animations.

My old workflow was a mess. I had one subscription for Kling, a waitlist-and-pray approach to Veo, a separate image tool for stills, and a folder of half-finished experiments across all of them. Every tool had its own credit system, UI, and export quirks. I spent more time switching tabs than creating.

A friend pointed me to OpenGen. It puts the big video models in one workspace: Veo 3.1, Kling, Seedance, Sora 2, Runway, Luma, Hailuo, and more. Image models like Nano Banana Pro, Seedream, Flux, and GPT Image are there too.

That was the selling point for me. I don't want to bet on one model. Each one has strengths. In my testing, Model A handled realistic product shots best, and Model B was better for stylized scenes. Being able to run the same prompt through different models without changing platforms saved me a lot of time.

What actually worked well

Start and end frames. I uploaded a product screenshot as the start frame, described the motion I wanted, and got a clean animated product shot. Adding an end frame gave me much tighter control over where the clip landed.
Fast iteration. The loop is prompt, generate, tweak, regenerate. Usually one prompt change got me from "almost" to "usable."
Mobile app. I made a couple of social clips on my phone while [commuting / waiting for a meeting], using the same models as the desktop version.
Commercial use and privacy. Paid plans allow commercial use (subject to each model's license), and they say prompts and outputs aren't used for training. That matters when you're making ads for a real business.

The numbers

Time to finished landing page video: 3 hours, compared with 5 days when I planned to hire a freelancer
Result: landing page conversion went from 2% to 37%, or the social clip got 23K views

Minor nitpicks

With 14+ models, the choice can be overwhelming at first. A short "best for" guide inside the model picker would help new users. Credits also go quickly if you experiment with the premium models, so decide which model you want before generating ten versions.

Takeaway

If you're a bootstrapper who needs decent video content without a production budget, a single hub for many models is much easier than stacking subscriptions. It hasn't replaced a real video editor for me, but it covers about 80% of what I need.

Curious what others use. Are you sticking with one model, or going multi-model like this?
