Sputtering Audio

[kdog509adam75+]

When I edit video in Video Studio Pro 2020, the audio stutters terribly. I'll open a video and select Multi Trim. I'll mark the cut in point where I want the edited video to begin. Then hit play to run the video to the point I want to mark the cut out. During that time, while the video is playing the audio sputter or stutters, hard to explain it any other way. Is that normal?? Seems to me it's not, but......When video is played normally, the audio is fine as is the edited video clip after I'm done trimming. It's only during the actual trimming process that the audio goes a little catty wonkers.

If you are using Smart Proxy files then it does appear that those are not applied to clips when using MultiTrim

You do not say what type of video you are using nor if you are using Smart proxy

I'm just editing GoPro video from some of my motorcycle rides. I'm not sure what Smart Proxy is.

OK, I found Smart Proxy in my settings and turned it on, but it didn't make any difference.

Could it be so that the audio codec on the video is something not so standard? GoPro is still quite big vendor that very much unlikely so. Have you tested with other formats on GoPro or a shorten videos? If you made own video with sound, can get the same problem when you try to trim that then?

What are your video's properties:

Have you monitored your CPU usage while sound is breaking, is that higher than normal?

Just turning on Smart Proxy is not enough, Smart Proxy files have to be created
First view Preferences (F6) – Performance tab, tick enable Smart Proxy
I allocate a folder on my D Drive to hold the proxy files, keeping my C drive clean. your choice

Back to the time adding any HD video will start the proxy process, Settings Smart Proxy Manager – Queue Manager will show the progress, once complete the clip will show a small icon as attached image
If the clips are already on the timelines then we have to manually create the proxy file, right click the clip for Create Proxy files, can be done from the library clip.
They do take a while to create but once done should improve timeline playback.

Just for the record, the GoPro -- at least the latest Hero 9 Black and other recent versions of the camera -- use MPEG AAC audio which is of course quite standard. I just bought a Hero 9 Black last week, so could check that quickly.
