I do game commentaries with Fraps, and the biggest thing I miss from Camtasia (which isn't an option for many fullscreen applcations) is multiple audio tracks.
Using Fraps to record both system audio and microphone input results in a single track, with extremely loud system audio and standard volume mic audio. It's very hard to get the audio level for system audio low enough (sometimes impossible, since I have to change it via in-app settings, Fraps ignores system volume levels), and it's all in one track so I get no shot at post editing.
Is there a way I can record a second audio track at the exact same time (ending at the exact same time) as the Fraps recording? I've seen multiple forum threads where the suggested solution is to start Fraps, then start Audacity (or another audio recorder) and sync up the audio files in post. Starting the recordings at different times makes it extremely hard to sync them up, and I'd rather deal with the volume issue than deal with audio sync issues.
Is there some way I can start Fraps and record audio externally, starting and ending both programs at the exact same time so they're in perfect sync? I unfortunately can't map multiple recording programs to the same hotkey, and pressing two buttons can result in unsynced A/V.
