Luma AI - AI Video Generation with Dream Machine

What do you like best about the product?

The voice and the lip-sync are the part that actually works: they came out convincing and cost relatively little. As a source of raw moving image it can get me to something usable in fewer attempts than other tools I've tried, as long as I stay away from anything complicated in frame.

What do you dislike about the product?

Credit consumption is opaque and absurdly disproportionate, and the image quality is not reliable enough to justify it. I've been a Plus subscriber. I wanted one thing: a woman on screen explaining something for 48 seconds. It took hours and ate 60% of my monthly credits, about 6,000, in a single session. The voice and lip-sync came out fine, but the image itself gave me the classic deformed hands, ridiculous enough that the shot was unusable and I had to pay to generate it again. What drained the account, though, was the part any editor does in five minutes: gluing six clips together and putting a background behind them. The agent tried it, failed, described its own method as heavy and of poor quality, and moved on while the meter kept running. The usage page showed: Sync Lipsync 2, 2,348 credits; Kling 3.0, 1,960; Luma Agent, 1,525; Nano Banana Pro, 225; ElevenLabs v3, 32. They charged me 1,525 credits for the agent talking to me. A quarter of everything I spent went to it asking questions, thinking and changing its mind, with not one frame of video out of it. Every question it asked me, I paid for, and nobody tells you this anywhere. It also generated 10-second clips for segments it had itself written as 3 to 11 seconds long, so I paid for footage that was never going to be used. At no point in the entire session did anything warn me what an operation would cost: no confirmation, no estimate. You find out when it's gone. This is built to spend your money freely and tell you afterwards. There is no guardrail between the agent and your balance. That's not a professional tool, that's a meter running in the dark. I run a company and I recommend the tools I use to people in my industry, and I won't recommend this one until they put a cost warning before each operation and stop billing customers for their own agent's deliberation.

What problems is the product solving and how is that benefiting you?

I use it to produce the moving image for my company's communication pieces: on-screen presenters, product and ambience shots, without booking a shoot or hiring talent. That part it solves well and it saves me time and production cost. The editing, the text and the animation I do afterwards in a proper editor. Where it does not work for me is as an editing or final-assembly tool: there the cost runs away and it ends up more expensive than doing it by hand.
