Jumping Video

Hi, I use Camtasia to analyse video footage - so it's a recording of a video. 

The recorded footage can look jumpy, does anyone have an idea as to how I can resolve this? It's really annoying to watch on playback.

Thanks,
Scott

What is a "recording of a video?" Camtasia imports a number of different video formats. Are you using a camera to record video playing on a screen or ???

Hi, 

Apologies for the lack of clarity. I use the software to analyse video, so I'm screen recording a video being played in Quicktime, and using the mouse layover to explain various things.

Once recorded, and once I play it back, the footage is "stuttery" and I wondered if it was something to do with the recording framerate or something?

Thanks.

I suspect it's the recording. What you can do is find a jumpy spot in the recording. Using the next frame control. View the recording one frame at a time. Odds are, you’ll see repeated and missing frames.

I'm a Windows user, so I can't speak directly as to Camtasia for Mac’s  performance.

What I can tell you is this.............

If I record a video playing. It doesn’t work well in most cases; it might record most frames for a while. Then start dropping frames. It’s an inconsistent process. Working decent at times then poorly at others.

End result.............the dropped frames are replaced by repeated frames.


The Dropped Frames account for the jumping.
You cannot achieve smooth motion when an object moves from A to B to C to D to E to F to G.
When B, C & E are missing, and other frames are duplicated to boot.
If you want to analyze video. If possible, you should download it.

Regards,Joe

I was about to respond, but Joe Morgan covered it all. You might see an improvement on a machine with a more powerful graphics card, to ease the burden of simultaneous playback and recording, but the real solution is to download the original video.
