Hi guys, I'm a little new to this. I've done some (very basic) video editing, and I've seen how audio from an external recorder can be sync'd with video. I'm currently waiting on my sound recorder in the post, and I'm sure the answer to my question will perhaps become apparent, but I think it's probably obvious to you.
I've seen how people clap at the start, then line the spikes in the audio, however, if the clip is quite long, I would guess that this timing needs to be adjusted throughout the clip ? I guess the whole audio is sync'd to the complete unedited clip, then the clip is edited as required.... and timing on the audio fine tuned ? And how is this done, what if you have no further claps, you just get used to the fact that it runs fast or slow, and adjust by ear ? ..... or am I imagining a problem that doesn't exist ?
