How can I record Video and Audio separately?

Q. I have a video camera that I would like to use due to it's high quality video, but since I am recording myself doing vocal covers for youtube, I have a rock band mic plugged into a usb port on my computer and would like to use the audio from that. I don't want to record them separately, I just want the video to be taken from the camera and the audio to be taken from the mic. Is there any way to do this?

A. Sure, in fact it is the preferred way as consumer grade camcorders don't record audio very well, especially music and singing. When you begin your recording session, use a sound marker; I use a clapper board but you can use a hand clap (my friend uses a dog training clicker). When you edit your video, add your mic'ed recoding to the time-line and after you line it up with the video (and audio) track and match the "clap", then delete the audio track of the video. If you mess up, you can always use the Back function of your editor (the editor doesn't actually edit the original video file, it makes a copy to work with).


Can we do something like SETI at home with a million cellphone cameras?
Q. If more than a few million dollars have been spent on the ET among us topic, directed toward the truth, the details have been kept secret and/or deliberately sabotaged = not necessarily a conspiracy = possibly independent sabotaging = It does not take many vocal dissenters to sway the vast slightly interested majority to negative and/or disinterested.

A million video cameras could record non stop pointed approximately straight up, daily from dusk to dawn, but 99.99% of the footage would be too boring for humans to watch. Accurate slant range can be calculated when two or more cameras catch the same event, provided the zoom setting can be quantified. But was it the same event? = most would be a tiny spot of light. Timing pulses recorded on one of the audio channels would greatly increase confidence that it was the the same event. Perhaps you can see a million dollars per year barely starts to make the program effective. Money for unattended equipment that is stolen, for lots of bits or bytes of data storage, for shipping cost to and from some central data processing centers. For internet bandwidth when the broadband data is sent by internet.
I'm not qualified to do any portion of this project, except a telephone tree/ would one of you like to start the process with a few video cameras per square kilometer in your dark sky community as a pilot program?
Approximately straight up so ET can't determine where the dead spots are. Do we need to know how many degrees of arc from the zenith each camera or telescope is pointing. GPS data on the other audio channel or multiplexed if there is only one audio channel. Likely user comments should also be recorded, which hopefully will remove some doubts about the data. I suppose some people will submit fake data, just because they can, and for other reasons. Please correct my assumptions and add details. Neil

A. NASA has a network of cameras to track meteors. It would also track UFOs. It would be a cold day before I would leave my cellphone laying on the picnic table all year long.


How could my band record music with good quality?
Q. We only have an HD video camera and we use the sound recording option. we want to get noticed but we don't have enough money yet to go to a studio in town.

A. download audacity, its free. you can record each track individually (guitar, vocals, etc) with the camera then mix it together in audacity when you upload it to a computer
