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

First realize that when you run the slide show, powerpoint is "reading" from the source drive and that reading from HDDs or SSDs is much faster than writing. If your recording HD content, you may be trying to write faster than your hardware allows.  Where are you putting the recording, the physical hard drive? For best results, I record to a RAM Disk and all source files reside on SSD's.
Also, does Windows 10 have updates in the queue? That can put a damper on system performance.

I do not have this problem, although I'm running v8.6 and not v9.  I have not had hiccups with Camtasia recording smooth PPTx playback and it's all standard hard drive playback and recording.
SSDs are fast but still very expensive and still have a reputation for occasionally losing data without warning.  So ... if any program required an SSD as essential for recording the screen, I would not have much respect for that program.  That said, as prices drop and stability improves, SSDs will become the preferred way to go for fast storage/retrieval.  Just not right now.

I run 7,200 rpm drives.
They can write data much faster than my computer can process it. Same would be true for slower 5,400 rpm drives.

But 5,400 rpm drives make for slow overall performance.
When you open a program like Photoshop or Premiere Pro.Requiring  2 to 3 GB of program files to run.
You will wait for quite a while. Transfer large files. Bottle Neck.

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.

rg: Regarding your "SSDs very expensive and still have a reputation for occasionally losing data without warning." What reputation? Please sight a reliable reference.

Very expensive? Baloney, I just bought two HP 240 GB SSDs for < $98.00 (Newegg). In 3 years when they're out of warranty, I'll replace them with 2 480 GB SSDs likely for less than $75.  Yes more costly than a 1TB HDD, now hovering near $50-60, but affordable AND 100 times faster, when you consider read/write & latency of HDDs.  Consider again all factors and RAM Disks are 100 times faster than SSDs. And Radeon's Ram Disk software is less than $20 for up to a 32 GB Ramdisk, if you already have the spare RAM. As a pro, I assume you have already populated your computer with whatever it can host, 16-32 GB.

If $100 scares you away from SSDs, you're in the wrong business. As my dad always said, "if you spend half of your waking hours on the road, buy a new Caddy or a Continental, life is then comfortable and enjoyable. If you spend 50% of your time in bed, buy the most comfortable mattress and pillow you can find." Forget affordability - it's your LIFE!

Well, I spend half my waking hours behind a computer so I have a system: three 1.2K monitors (1920x1200), 32 GB, a 4790K CPU, a 10 TB home/small bus 2011 server,  two WD black 512GB m.2 ssds and an enterprise HGST 1TGB spinner. And my backup computer is IDENTICAL but with a single 4K -28" monitor. Costly, yes: But this is my BUSINESS and over the last 4 years, my systems have paid for themselves a hundred times over.

Never have I heard of SSDs having your "losing data" problem- they do however have a "half-life". Search Intel.com for "write amplification errors" - somewhat like a spinning HDD drive's ever-present CRC errors. But when an SSD goes "bad", you can't write to them but they'll exist in your archive library for 50 years as an always readable data host for the way it was on YYMMDD (when it failed).

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

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.
