Okay well since you have the pro subscription this means you have a lot less credit so you need to be a lot more strategic. You should be able to get a few generations within the Gemini chat daily and then if you go to Google flow through Google Labs you can use your credits. I would suggest you stick to the VO3 fast model. It uses 20 credits and is the most bang for your buck. The $100 be a quality model is not much better. Definitely not worth X5 the credits. Keep in mind you can only have 8 seconds with audio. If you try to use any other features, you will not have sound. It's damn near impossible to have consistency from one 8-second clip to another so if you're trying to make a long story, you have to get creative and keep in mind that the characters and scenes are not going to be looking the same, take your time with the proms and use Gemini to help you craft better ones. I find that if you ask too much, it's probably not going to deliver. I try to go for Cool concepts, so even if it doesn't work out, I'm more likely to get a cool fail
