Re: So, I went and started an anime review channel on Youtube...
I really wouldnt have time, unfortunately (as it is, I'm having to juggle getting the videos for my channel ready with my freelance work, plus all the usual soul destroying real life crap)
But I can give you one tip that might help. If you're going to record your commentaries anyway, you might do well to have your script together as a really simple list of things you want to mention. Get it printed out, but have it broken up so that it loks like this:
1. Greeting and intro.
2. Point number one.
3. Point number two.
4. Point number three.
And so on.
Have everything there in your printed script, but space it out so you can find things at a glance.
If you know what you want to say and roughly how you want it to come across, you won't really need any editing for grammar or other issues.
Just beware of overly long sentences. You'll run out of breath, or start to sound unnaturally forced if you read from the script by sight.
