Recommendations for cmobining MP3 with video (which needs editing)

  • Updated 2 months ago
I have read here that it is common (preferable?) to record audio separately, as with Audacity. I did that and edited the resulting audio track until it was the way I want it. If I record the sound with the video, the video seems to jump around because chunks are missing. I recorded the video piece in Camtasia. Now that I've read several posts and watched a few videos, I am still unsure how to proceed.
1. Should I edit the video portion before importing the audio into the project?
2. I assume I will have to lock the audio track and then move the video track so that it is exactly where I want it. However, if I need the video to be longer at some point, is it possible to select that piece of the video only and expand it? I've not tried to do anything like this before.
Thanks.

you might find that it is a lot easier, editing wise, to record your audio/narration as you do your screen capture; that way, the audio/video starts out in sync, and cuts can easily be made that affect both the audio and audio at same time

but there are so many ways to approach this, you'll have to test and see what approach works best for you

I do a lot of screen casting work, and have found that certain protocols can optimize the process, workflow wise

perhaps, this somewhat lengthy tutorial might be helpful?

Very detailed tutorial, just the kind I like best. 2 questions. 1. Do you usually make all these small captures instead of one big one? Why? 2. When I click on "edit," the choices scroll off the bottom of the application. I can't see and can't get to "Preferences." Is there another way to get there? Thanks.

yes, I usually do make those numerous small captures; because if I mess up a capture, I can easily just redo that section; if I made long captures, a serious mistake could wipe out a lot of work product; it's just easier to keep track of short capture snippets 

not sure what you refer to re ... When I click on "edit," the choices scroll off the bottom of the application. I can't see and can't get to "Preferences."

but try using the shortcut ctl-,   that should open the same dialog?

I've done both but I agree with kayakman... recording the narration with the video is often easier and I've not had any trouble with resources taking that approach. When you do the narration separately, you just have to be ready to do a lot of track editing to align your audio with your video... it's a bit tedious but certainly not difficult with all the tools in the camtasia toy box.

Thanks for your replies. I usually do record both audio and video at once. The problem is that I am showing students where to click and what to type on library web pages. When I make cuts in the audio, it makes the video really jumpy--you can tell it was editing but not by anyone who knows what he's doing..... The mouse position should be consistent from moment to moment, not jump from a tab to a box to a... I've tried three times to get this right with recording both at once. Now I have a correct, edited audio. I was hoping to record a video track that did exactly what the audio says to do. I would prefer to not have terrible-looking tutorials.

  I'll go watch that video now.
