video export quality poor when audio added

Can someone please help me with this?

I'm trying to create a video. I recorded in 1080p and am producing to 720. Every time I add an additional audio track to my video, the export quality diminishes significantly. I worked in stages and found that the first time I exported the video with the music file I noticed a drastic decrease in quality. I compared side by side (knowing that was the ONLY change I made). Why? How can I prevent this?

My advice: don't use Camtasia for audio editing.  Audacity is shareware available for most platforms.  If you have a few bucks to spend, I like Adobe Audition.  There are many others.  Get the audio right then import it into Camtasia.  At least that's the way I do it.

HTH,
Tony

I'm assuming you mean that the video doesn't look as clear? Perhaps the export quality is fixed (X megabits per second) so with audio, and a fixed data rate, there is less room in that for video?

I'm not using camtasia for audio editing, I've imported something from audacity and the sheer act of adding audio (or removing it) causes my export to look extremely blurry. I had a file I was working on and the only change between exports is that I muted a track. Export 1 with the audio is fine, export 2 with muted audio is super blurry. This doesnt make any sense to me.

Could we have a look at your settings when you're exporting?

I'm gonna make one more suggestion, and if it doesn't help, I think you should try contacting our Tech Support and opening an issue there, because they can help you send us the actual project you're using, and we can try to reproduce the issues. You'd do that at https://support.techsmith.com

So, my suggestion is to switch from "Export to MP4" to "Export to Main Concept (mp4)". The default quality there should be good, but you could play with it a little. If you swing it too far to the right (max quality) the file size will be enormous.
