Audio and video "stutter" during transition to new clip

  • 4
  • Question
  • Updated 4 years ago
First off, my level of proficiency with Camtasia is that I can record my screen, do the simplest of editing tasks, and then produce a file for Screencast. I've messed around a bit, and browsed through some of the tutorials and manuals, but mostly I'm trying to avoid geeking-out and spending months to learn it well and then never use those things. In other words, I've been trying to do "just in time" learning so far.

And then I get nominated to film my daughter's elementary school talent show and produce a DVD. I bowed out because neither of these are my strong point, but I was told it was either me or nobody, so I stepped up.

(I understand that Camtasia isn't really designed for this, but I'd rather use something I know a little bit than start from scratch with a new program.)

So essentially all I'm trying to do is combine about 20 different .MP4 files (converted from .MTS using Techsmith's helpful program/wrapper - thanks) together, do the most rudimentary editing (removing dead spots between acts, etc.), and then produce a file that I can burn to DVD with a different program.

When I add a 2 or 3 clips to the timeline to work with, I can cut non-essential areas out of the first clip no problem. But then when the playhead hits the exact area between clip #1 and clip #2, the audio stutters/repeats itself exactly three times, and the video seems to kind of repeat in its own way while this is happening.

(Ultimately, I was planning on combining all of these clips together, doing simple transitions, and then putting in markers so people can go chapter-by-chapter to get to their child's act.)

I've restarted Camtasia/rebooted/closed all other apps/etc., which doesn't seem to make any difference.

I'm open to all ideas...thanks in advance.

Scott,

I can relate to your story. I haven't been tapped for a DVD yet, but I have a daughter, and I occasionally get tapped to edit a performance. I'll do my best to offer some helpful suggestions...

The markers will not carry forward into the DVD authoring program. You'll create your DVD menu and chapter points in the DVD authoring program.

You don't need to string all the videos together into a single video. You should be able to take the individual MP4 files into the DVD authoring program. It's probably a good idea to test this process out with 2 or 3 MP4 files to work out any kinks in your workflow, and then proceed with all 20 MP4 files.

Hope this helps.

Dave, How about addressing the issue that the video/audio is "stuttering" instead of suggesting another program or another way to do it. You should be able to cut and item and it not pause/repeat itself during playback!

Quite. Original poster was trying to edit video content consisting of different clips, cutting sections out and closing up the join gaps.  OP encountered problem of Camtasia preview playback stuttering when it reaches the joins.  Instead of addressing this issue, Dave is basically saying don't use Camtasia to create joins like this - despite the fact that Camtasia is marketed as being able to join clips and create transitions between them.

Can you tell I've got the same problem and am quite annoyed about it....

Although I love Camtasia and can make it work for a lot of stuff, this would not be one area where I would try to use it.

I have done many, many DVD projects since I have 7 grand kids :-) What I use is Adobe Premiere Pro and Adobe Encore (they integrate prefectly for a project like this). Although there is a learning curve, they are definitely the software to use and you can get really great results.

There are other programs you can use (i.e. Premiere Elements, Pinnacle Studio, etc.) that will do the job as well.

The projects I have done have been awesome and I have been quite the hero to my kids when I give them these DVD's documenting a particular part of life for their kids (my grand kids).

Kurrykid - thanks for the frank advice. In the past I'd jump at each new "thing" I got to play with, but I'm trying to be better about that now. But I'm also trying to be smart enough not to spend 40 hours trying to put a round peg in a square hole...

Dave - that makes sense to me, I think. I'd then use Camtasia to edit each of the MP4 files as I wanted, and then produce them so the DVD authoring program would just pick each one up and create a chapter out of it, right?

Sounds like the most efficient way to handle it for now...

Again, thanks to both of you.

That's exactly right Scott and that is the workflow I use.

One thing I would do to test is to render it out and see if the stutter is there. I think sometimes the stutter happens in the preview but isn't actually there.

Any chance you can render it out and see if it's in the final output?

It won't solve why the stutter is happening but at least we can see if it's in the output.

Thanks.

I have the same issue of stuttering playback in preview.   The stuttering is never there in the produced end result. It's a preview issue.  But the fact you can't use Camtasia to preview what you're working on is a serious limitation.

what you are experiencing is most likely due to project complexity and/or your system limitations

best workaround is to break the project into smaller sections, using the Library, and edit out one section at a time

I think you are missing the point here.  If TechSmith is promoting Camtasia as a bona fide video editor then there should not be any limitations regarding HOW you edit.  The problem is in the software and they have the responsibility to fix it.  Just saying.

I agree with LittleD73 , it is the responsibility of TechSmith to fix these problems.  They promote and market Camtasia as being able to do something that, frankly, it cannot do.  There is no problem with my system - i7 processor, 8GB RAM, 1TB solid state hard drive.  I switched to using Lightworks Pro, which is brilliant for video editing, much better than Camtasia and with no stuttering at all.

Camtasia just isn't up to handling projects like this, although it claims to be a video editor, forget it for this kind of use. I still use it for basic screen capture, but for video editing, no way.  I've moved on to Lightworks Pro, which is awesome and doesn't have the annoying stuttering problems that Camtasia has

Hey all - I haven't used Camtasia much, as I finally went Mac a year ago and Final Cut Pro is more than I could ever dream of.

But the last time I used it, it was as kurrykid said above - that is, the "stutter" was not in the final, rendered video.

Still frustrating that it DOES appear in the preview, but was a much smaller issue to me knowing that it wouldn't be a problem in the final version.
