Export to format other than avi results in very jerky video

Hi all,

Am using Camtasia Studio 7.0.0 as it's what my company has access to, and every time I try to export my video to an mp4 it results in an extremely jerky video, where screen is almost vibrating. It's like it's bouncing up and down at very high speed. Am trying to build from a single imported avi file now. Exporting to HD helps somewhat, but is still "bouncing" up and down.

I can export to an avi and it's fine. I'm using a custom set of dimensions but have tested with some of the default, auto locked aspect ratios and am getting the same result.

Any thoughts? Thanks!

what type/where from are the source files?

as a quick test, make the AVI and then use that as your project file; does that work?

Source files were video capture of my screen using Camtasia - so clipped and edited avi files. No audio required. Have tried exporting these as a single avi (which plays fine) but even running a new project with that single file as the only imported file, and then running produce to mp4 with no settings changes results in a "bouncing" file.

Have tried playing around with frame rate and other such settings, but have only managed to make the video bounce or vibrate faster, rather than get rid of it.

I haven't used CS7 for 5 years, but what you described never happened to me

more facts might help here ...

describe PC and operating system

what capture dimensions?

test by try capturing full screen; edit and produce using those dimensions; does that help?

have you tried downloading and trying CS8 or CSp 30 day demo?

Hi, thanks for following up. Haven't managed to resolve, but have determined that export using the DVD pre-sets results in an acceptable video. Need to improve the quality, but can work on that using normal methods + other threads.

Unfortunately downloading other versions isn't an option within my company - we're licensed for CS7 only and don't have download/install access. PC was a thin client, but 8GB RAM and 2.7GHz processor. Did also test with a full screen capture, and produced using identical dimensions but same result. Just appears to be an issue with the export to mp4 - not dimensions.

Anyway, thanks for your support - I'll progress with improving the DVD pre-set quality for now.
