Just wondering if someone could answer this for me please? I am wanting to get into video production and editing. Basically I am wanting to record video reviews of different things that I own. I am also wanting to purchase a USB microphone to use on my iMac. I will be shortly be replacing my current camera with the Panasonic dmc-fz200 camera which has a video recording capability along with a built in microphone for recording the audio. Although from what I've heard online, the audio isn't very good, hence the reason I want to use a USB microphone. My thinking is this: I am wanting to record the video review, then get the video off of the camera's SD card and into Final Cut Pro. Once in there I want to delete the audio track that my Panasonic dmc-fz200 has recorded. I believe that it's possible with Final Cut Pro to record an audio track (by going to the Record Audio option in the Window menu) at the same time as the video would be playing in Final Cut Pro. Now, obviously the audio would need to be (for want of a better word) in sync or keep up with the action that was going on in the video. To try and clarify. If I were pointing at some part or button in the video (of what I was reviewing). I would obviously need to be at that point in my audio commentary that I would be recording. I was wondering if the audio commentary that I was recording was either getting a little ahead or behind of what was going on in the video, is it possible to slow the video down or speed it up so that both the audio and the video are keeping up with each other? Presently I record tech guides on my iMac on doing various things on the iPhone and iPad with the built in mic on the iMac, along with two other applications I use (Reflector and Screenflow). Doing this with these two applications when I get a USB microphone should be a simpler task than doing the video reviews recording with the Panasonic camera, Final Cut Pro, has its possible to tell Screenflow which microphone to use prior to beginning recording (i.e built in microphone or an external microphone) and also Screenflow allows me to edit the video too. So in this scenario, the audio and video would be both recorded at the same time and I wouldn't have any issues with video and audio not been in sync/getting ahead/behind one and other. So I shouldn't have any of the problems I have mentioned above with using my Panasonic dmc-fz200 camera.
