Captured video in Camtasia is very jerky

  • Updated 3 weeks ago
I am using a Sony a6300 connected to my desktop PC via an Elgato Camlink.

When I record through SnagIt I have no problems at all, which suggests I have all the right drivers, physical connectivity, performance, etc I need.

However, when I capture video through my camera in Camtasia (I have the latest updates installed) the video is unwatchable - kind of like the frame rate of 1 per second! The audio associated with this plays flawlessly.

Any idea where I might look to resolve this?

The only way to resolve this, is to set the Sony to record at a lower resolution.

Camtasia limits FPS with camcorders.At 1280 x 720 you can record at 30 fps. At 1920 x 1080 it drops to 5fps.
The Sony a6300 being 4K must drop it even lower.
I don't have a 4K camera so I've never seen the frame rate in the drop down menu for camcorders for 4K.
At 2304 x 1536 its 2fps. Why it gives me that resolution option, I don't know.I have a Logitech 1920 x 1080 webcam.
You can see the setting yourself in teh recorders toolbar.


At 1280 x 720

Thanks for the response, Joe. So SnagIt is considerably more capable than Camtasia in this regard? That is somewhat surprising and pretty disappointing (not shooting the messenger, of course - I appreciate the info).

All that said, I am still somewhat confused. I dropped the Sony down to "720/30" (which I assume means 1280 x 720 @ 30 fps). I have the same unusable video. But what is confusing to me is what I see in Camtasia. I have set the camera to be 1280 x 720 (within the Camtasia capture window, I mean), yet I still see 1920 x 1080 in the Properties window (and 60 fps). Can you clarify what this means?

By the way, Output Size option has just this one option.

That's a different window than the one you want, that must be the codec window.

You want to select from the recorders toolbar.

tools/options/format settings/ Then you will see the Camera settings/properties window.
Like in my first image above.

Unless your streaming software is overriding what Camtasia normally does.If that's the case.

Thanks Joe. My image was a bit misleading, in terms of how I had the windows aligned, but the Properties window displaced was reached via Tools/Options/Format Settings.

At this stage I am getting concerned that TechSmith is just going to say that the CamLink is not a supported device and kinda pass the buck (I saw a comment to that effect in these forums from 10 months ago, so hope that has moved along since). The restrictions on what Camtasia can pull in are very disappointing though.

Thank you again for your help, Joe.

I've recorded my webcam separately using Logitech's free recorder.
 

You have to sync the audio to the video in the editor.But you can get 30fps 1920 x 1080 video if you want it.This software won't help you. But another program could.It's something to consider

PS: Can you confirm that SnagIt is more sophisticated in capturing video through Camlink/DSLR than Camtasia? It's just plug-and-play and I can record at pretty much any resolution I want. I find it surprising that a "mere" capture utility is able to record much better quality than a full-fledged video editor.

Even Skype can do a much better job than Camtasia :(

I cannot, I'm just a user like you.

However, SnagIt captures just the camcorder in camcorder record mode.And just the screen in screen capture mode.

I know that the reasoning behind  the lower frame rate in Camtasia is. TechSmith wants to ensure the .trec recording is a great recording.

If you have a low powered computer and try to record 2 HD videos at the same time. You an wind up with so many dropped frames. Neither recording is usable.

SO, this restriction is really unnecessary for anyone with a strong enough computer. It should be a setting we could override. Perhaps with a warning of what might happen?So tech support doesn't get hammered with support requests needlessly.
