I am using Camtasia studio 9.1 on windows 10.
before i run camtasia and start recording, every thing and every motion on my screen is natural and smooth. for example when i run Microsoft powerpoint 2016 and run its slideshow, video is smooth and great, but when i  start recording, PowerPoint and slideshow is not smooth anymore and any object appears Discontinuously so recorded video is not smooth as well.  seems it's not only about powerpoint and in general when i start recording, all motions on my screen are not smooth any more ( e.g. when i drag a page with mouse ). as a result  powerpoint's nice animations are not shown in normal smooth way in final recorded video.
any help please

What are your computer specs? Does it meet the minimum requirements for Camtasia?
https://www.techsmith.com/camtasia-system-requirements.html

Also, Power Point requires system resources as well.
If you don't have a strong enough computer. You may not have enough power to run both programs
simultaneously.

Did you realize you can a record Power Point presentation with Power Point?

If you want to edit it further in Camtasia.You could do that as well.

thanks to all guys 
my system is not weak:
hard disk is SSD 
memory: 16 GB  
processor : corei7 4720HQ

capture frame rate : 30

windows updates are not running during recordings.
i tested & noticed when i haven't started record, when i simply hold the mouse left key & drag my windows explorer windows to left & right, it is natural and smoothly and fluently moves to right & left.
but when i start the recording, now when i do the same thing, i see  that these motion has hiccups ! 
so i think it is not only about PowerPoint and i think when i start recordings, every motion on my screen is shown with hiccups !

I agree, your system is not weak.

Sounds like a graphics driver issue or something along that line to me. But that's just me and my "Best Guess"

Tech support can figure it faster and easier than we can batting around ideas here in the forum.
I would like to know what it was. The diagnosis could benefit other users down the road as well.

i am on Lenovo y5070 laptop which its screen size is 15.6-inch
i checked my drivers are up to date.
i checked my desktop resolution was on highest level which was 3840 x 2160 ( which is shown as system recommended ). i changed my desktop resolution to all available values one by one and noticed that when i set desktop resolution to 1440 x 900 or 1366 x 768 , i get the desired result & no hiccups occur and everything is ok !
1920 x 200  and 1600 x 900 resolutions are also ok.

so i am confused finally what resolution to use.

i noticed that recording with these different desktop resolutions, the final mp4 video would have different characteristics such as Data rate & total bitrate (as shown in following screenshots).

i don't know what these parameters are and i don't know whether they affect the quality of final mp4 video or whether they affect the size of final mp4 video ?






so in short, i simply need to know which one of these resolutions will be better to select and use :
1440 x 900 
1366 x 768
1920 x 200
1600 x 900

thanks in advance

Okay, so the fact that you’re running a 4K monitor is dragging your system down makes sense. 4K is quite a drain on resources. That being said.

If it were me I would go with 1920 by 1080. That’s a nice high resolution and shouldn’t give you any trouble.

Data rates and bit rates fluctuate depending upon what you are recording. I wouldn’t concern yourself with that. In general, if you’re recording a static screen without many colors or movement. Your data and bit rates will be generally low.

If you are recording a dynamic and moving screen with bright colors. Data in bit rates can go through the roof.

Audio is part of the equation.

Bear in mind that when you reduce the resolution on your 4K monitor to 1920 by 1080. The monitor will look somewhat blurry to your eyes. As opposed to what it looks like an 4K. However, the actual recording will be at a normal level of sharpness at 1920 by 1080.

Just be sure that when you go to create your videos. Your project settings and production settings are 1920 by 1080.

Regards, Joe

You could still talk to support and see if they think there's anything that can be be done.But I suspect 4K is the problem.Power Point has to render it on the fly  and Camtasia has to record it. It's just to much.

thanks a lot joe, your explanations are great.
i tested 1920 by 1080 and i still  have the same problem at this resolution .
but when i set to 1920 by 1200, there is no problem and result is ok.
so would there be any problem if i continue using 1920 by 1200 resolution which seems to be good for me ?  ( i checked my camtasia settings is set to 1920 by 1080. )

I'm not a Power Point user.
Can you resize Power Point so it plays within a Camtasia 1920 x 1080 recording window with the monitor set to 1920 x 1200? If that's the case I say go for it.

I don't understand why 1920 x 1200 would be smoother. Theres more pixels for the computer to deal with.It seems you have something odd going on.
If you plan on doing this a lot. A 1920 x 1080 secondary monitor might not be a bad thing to get your hands on.

when i set to  1920 x 1080, the width of the screen is bigger than  1920 x 1200 . is it normal ?
but as i said, in 1920 x 1080 the problem still exists.

by the way i didn't get your statement : 
" Can you resize Power Point so it plays within a Camtasia 1920 x 1080 recording window with the monitor set to 1920 x 1200?"  why should i resize the powerpoint ?  please read the following :

i run camtasia recorder,
set record Area to "full screen" & start the record,
i run PowerPoint & hit F5 which starts full screen slide show
after some seconds i stop recording.
i played the movie and i see that entire PowerPoint page is recorded so no need to resize PowerPoint windows since entire page has been recorded in the movie

The reason you’re seeing black bars on the side of the screen when you set the resolution to 1920 by 1200. Is because of the aspect ratio. 1920 by 1080 has an aspect ratio of 16 by 9 and so does 4K. That’s why the image fills the entire screen at those resolutions.

1920 by 1200 has a aspect ratio of 8 by 5. So in order to display the additional vertical pixels in the given space. The horizontal pixels have to be drawn inward giving you black bars.


Being that I don’t use PowerPoint. I only have it because I have office. I’m not that familiar with the program. I realize now that most PowerPoint presentations are 16 by 9 aspect ratio. So as long as Camtasia makes the recording in 16 by 9 at 1920 by 1080 you should be all set.

All I can say is give it a whirl and see what happens, see how good it looks.

With regards to resizing PowerPoint. I was thinking more along the lines of something like this which in your case I don't think is necessary.

Take for instance. I have a 32 inch 2560 by 1440 primary monitor. If I wanted to record a tutorial about Photoshop for instance. And I didn't want to use my secondary monitor which is a 1920 by 1080 monitor.
I could set Camtasia to record a 1920 by 1080 window on my monitor. Then I could size Photoshop to fit within that 1920 by 1080 area. And just like that I'm recording at that resolution.
I've actually done it more than once. My secondary 1920 by 1080 monitor monitor is 23 inches diagonally.
On a 32 inch monitor at 2560 by 1440. 1920 by 1080 measures 24 inches diagonally. So the recording area is actually slightly larger than my secondary monitor. LOL.

Anyway, I'd be curious to know how it turns out.

thank you very much for these great explanations. i am so sorry because my English is not very excellent so i didn't get some parts of your sentences  since i think some of your sentences were Conversational English ( if i don't mistake)

for example i didn't get what do you mean by saying :

" So as long as Camtasia makes the recording in 16 by 9 at 1920 by 1080 you should be all set."

" All I can say is give it a whirl and see what happens, see how good it looks."

so that would be great if you tell me in short (via simple sentences) do i have to perform any additional settings ?

can i start produce my tutorials in 1920 by 1200 on my system & run PowerPoint in full screen slideshow ( which has beautiful effect such as PowerPoint transitions in full screen mode) ? 
by the way  i'm not using camtasia Add-in in PowerPoint since i need to capture my desktop contents in addition of PowerPoint inside. instead i record using the camtasia recorder itself  ( not the Add-in)

thanks

I did some testing.Record  using the recorder itself. No additional settings required. {:> )

Full Screen slideshow is excellent.
