Camtasia 2018 Recorder - Is anyone else experiencing a few black frames near the start?

If I could reproduce this consistently I would / will report it to Techsmith Support but for the moment I'm curious about whether anyone else is noticing it and whether it may therefore be a general problem or something specific to my system.
I just recorded a couple of tracks which, when I played them back, seemed to flicker for a moment. Certainly enough to provide a "whoa, what was that?" moment.
It seems to be always within the first second or so of a recording. When I step through the recording frame by frame, in one example frames 1 through 12 are normal, frames 13 and 14 are black.
In another one, frames 1 through 9 are normal, frames 10, 11 and 12 are black. In yet another, frames 12, 13 and 14 are black.
The only one that HASN'T had it this afternoon was one where I was recording the Camtasia editor playing back a project.
The sound seems unaffected.
Is this something that anyone else has noticed? (I'm on the 2018.0.1 patch.)

  • Bemused, since I can't think of a reason for this happening seemingly only in the first second.

Yes I have had that problem and no I don't think it is a bug with the Camtasia software.  In my case I was blaming Windows 10 although that might be unjust.  There are a variety of reasons why Windows 10 can just start doing other 'more important' things and our programs are left waiting.  Your initial delay might be because it hasn't yet allocated enough memory or created the 'sand-box' for your program to run in.  Once that's done, your program runs faster.  The reasons I think blaming Windows 10 might be unjust is, that operating system is calling DLL files in a different way and older programs on the system might not be compliant with the overall design.  In my case, Microsoft Mail which worked fine in Windows 7, always seems to be involved when my system is going slow.  Initially I used the free software (Microsoft site) Process Monitor and Process Explorer, which with a learning curve will show you what is hanging. It was always EXPLORER.EXE, which is the operating system and I couldn't dig any deeper, but now I think it's the new format for calling DLL files and legacy software which hasn't been updated to play ball.

this is a know issue per tech support; I get it consistently with trec captures, always 1 to 3 black frames at start of capture

tech support's fix for me was to have me edit the registry to change Recorder from hardware to software mode; it worked

Much appreciated.

It's annoying because I'll have to either:(a) Modify my recording technique and clip every recording; or(b) Take the chance that going to software mode won't cause any other side effects, and because(c) I've never had this problem with any previous version of Camtasia.

Kayakman, has this continued to work well for you? Have you found any other changes that occurred after editing the Registry? I'm getting really tired of having to trim out black frames at the beginning of clips and I'm about to try this solution.

I spoke with tech support on this issue. They said changing this setting shouldn't have any ill effects on the recorder.
I was skeptical about changing this setting myself. That's why I contacted them personally.
I pressed them pretty hard on the issue.The person who I spoke to's position was that they run tests before they release fixes of this nature.

To be honest, I'm not sure how a graphics card would contribute much to a screen recording.A graphics card's job is to generate what you see on the screen. With the exception of Nvidia's shadow play screen recorder. But let's not open that can of worms. LOL.

There is a newer support article covering this registry hack/fix.

I had to get rid of one of these again today, but it was recorded before I made the change. We'll see what happens the next time I do a recording.

This wouldn't be such a big deal if Camtasia had an easy way to delete single frames, but I've found that it's really difficult to select just one frame, even when moving the cursor with the keyboard or cursor buttons. If anyone knows of a simple method, please let me know (I'm actually hoping that I've missed something obvious enough to be embarrassing).

FYI ... kayakman is on travel, but ...

the registry thing worked OK; but I went back to using the default and just live with black frames; they are always at start of each trec capture, so very easy to find and delete by walking/selecting the few frames

When I started recording, the first second or two is throwaway footage anyway. So those black frames have never affected me personally as they are always discarded.

However, what strikes me is this. If the way to correct this problem has existed since Camtasia 8.
And it's to disable hardware acceleration. And utilize software mode only. Why hasn't this been hard-coded into the program long ago?

If it doesn't harm the performance of the recorder. There's no logical reason that they shouldn't have changed this long ago.

Myself personally, I think it must harm the performance and that's why they offer you a hack instead.

Why they can't get a handle on after all these years and fix it is the next mystery?

There's some bugs that TechSmith just can't seem to fix. And there's really no excuse for  this.

Yeah, what you said.

Why they seem to prioritize adding new features that they think we want, rather than providing frequently requested features and fixing bugs, is beyond me. It's bordering on ridiculous.

Or, taking away features that they think we DON'T want, but that's more of a Snagit team issue than a Camtasia team one.

Same thing is happening to me.  I've had Windows 10 for as long as it's been available and never had this problem with any previous version of Camtasia.  I will make the regedit change but this shouldn't be necessary.

This has been going on for a very long time.
For myself personally, I'm always deleting the first 1/2 second or more of a recording by default.
  I start a recording but don't start talking or doing anything, the moment the recording starts.
So I'm trimming the start of every clip . And those black frames get removed in the process.
