Choppy juddery video Zorin 7.1

Hi all,

Newbie and first post.

Installed this on quite a powerful new build. 8gb ram and AMD 10 processor but video is choppy. Not unwatchable but juddery all the same. The videos were created on window 7 using Camtasia which I believe will not work on Zorin.

I am willing to change distro if it will help. Videos are my main hobby…grandkids…so if I cant get smooth playback/production it may need to be back to Msoft >:( >:(

Any help appreciated.

What are you trying to play them with ?

Have you tried them in VLC ?

What format are the videos ?

VLC and inbuilt media player.

Made in Camtasia and run perfectly in win7. Formats are mp4, h264, and m2ts.

Video side is quite important to me. Should I change for another distro or revert to MS?

Thanks for reply.

Dunno how to answer that … I personally have had no difficulty playing video in Ubuntu based distros (and Zorin is Ubuntu based).

The fact that you mention m2ts makes me think they’re high definition video ? … these are FILES right, not a DVD/Bluray ?

What graphics card do you have, and which drivers are you using ? … can you open a terminal and run this command:

sudo lshw -C display

and post back what’s returned in the terminal.

HI Skronk

Have a look at this it might help

Good luck

Tried it. Just the same. Its the same in VLC and videos player and in preview in Openshot !!!

You’re using the open source radeon driver … the proprietary fglrx (catalyst) would probably be better…
(it would also likely provide hardware decoding)

I’m not familiar with Zorin, but is there something in the menu’s called “Addition Drivers”, or “Software & Updates” ?

If you can’t find anything in the menus, try opening a terminal and running:


If a dialog opens, select the “Additional Drivers” tab.

Are there any drivers listed there for activation ? … if so what ?

In Zorin You should find additional drivers here

Start>System Tools>System Settings>Additional Drivers


Ideal … cheers Emegra … is that Zorin 7 ? :slight_smile:

used the code and installed proprietary driver. Much more choppy now. How can I get the Radeon driver back ?

Also no videos will play now if I select video option instead of VLC. Vlc really quite bad now. Need to roll back to Radeon driver…but how ?


Which drivers are listed in Additional Drivers ? … which is what I asked before.

And what’s the output from:

sudo lshw -C display

again ?

Can you type EXACTLY what’s listed in Additional drivers (and say which is currently selected) … or attach a screenshot.

You’re STILL using the open source radeon driver.

The above is a copy of post 5 where the Radeon was installed. You may have missed my reply ? I replaced it with the proprietary driver but that made video almost unwatchable…choppy, freezing etc. I have now re-installed the Radeon driver and this has returned things to what they were. Will attach screenpic shortly.

Hope this works !! from 2013-12-06 08:07:41.png

Obviously not. Don’t know how to attach screenshot.

Hi Skronk

To attach a screenshot (or any file), under the main text box you’ll see “Attachments & other options”, below that you’ll see a sub section headed “Attach” click “Choose file” and navigate to where you saved the screenshot and open to add the attachment, the site has a file size limit so you may have to resize to no larger than 1024kb

Hope this helps

Good luck


Thanks Emegra. Try this then…

Does not seem to offer the last step…Additional Drivers !!
