Yuuko was good, yay.
and lol monica rial, she is just everywhere. I'm going to be meeting her in person soon too, I actually like a lot of her work tho
What the person should of done is recorded the sound from the trailer in Audacity using Stereo Mix/Wave Out Mix and recorded it directly from the sound card rather than using a microphone.
then use a screen recorder to record the video and naturally then just put the two together.
or if you have one, a screen recorder that also records sound so you don't have to go through the whole audacity bit.
I would do this but my Sound Card doesn't have the Stereo Mix/Wave Out Mix functions....
