I’ve never worked with audio editing software before, so I honestly have no idea how to go about doing what I would imagine is a fairly simple and straightforward task:
I have two video files that I want to put together into one continuous stream. They are both half of a full video. Problem is, it’s not a simple concatenation procedure. The end of the first half goes black for 2-3 seconds at the end while some audio fades out. I want to put them together without the black part in between, and I want to have the fade-out appended over the first few seconds of the second half. Basically, I want there to be a period in the middle where the two tracks are playing at once. How might I go about this?
I’ve already got the video stream put together how I want. I just need to edit the audio part before I mux it together.
You did it backwards. Never cut the picture first. It’s far easier to get the sound right and then work the picture around that. Cutting the picture first and then cutting the sound sometimes requires an Academy Award winning editor.
If Audacity will not open the sound part of the movies, then you will have to talk your video editor into Exporting WAV files for Audacity to open and cut. DO NOT use MP3 anywhere.
I can open them. I just don’t know what to do with them once they’re in the program. I would like to know how to go about overlapping them for a second or two so that there appears to be a flawless seam between the two parts. As I stated, part one ends a scene and the audio fades out for a second or so until it’s quiet, and part two picks up at a new scene. I want to overlap the fading out of the first part onto the new scene so that it sounds good, and there’s no rough stopping of audio.
I know about “crossfade”, but I don’t know if that’s what will best accomplish my task. Even if it is, I have no idea how to do it.
Working with multi-channel sounds in Audacity is a bit awkward because Audacity does not support multi-channel tracks beyond 2 channels (stereo).
When you move tracks around you will need to be careful to keep all of the channels for each multi-channel sound in synch.
You would probably be better to use your video editing software to perform the cross-fade. Most video editing software supports more than one audio track, so you can overlap the two parts of the audio on different audio tracks and apply a fade-out to the end of the first audio section.
It was a bit of a pain in the butt, but I think I got it. Just loaded both files into Audacity, alligned them up where I needed, and then mix/render the seven sets of tracks together. It’s outputting right now, so I’ll have to wait and see the result, and to see if I have it synched up properly.
