Hi, I have noticed that playoff an audio track in Spotify use very much less power than playing of same size audio track (without video part) in Camtasia. Now how is this big difference possible? (Ctrl + Shift + Esc gives the attached image; "Prosessor" = Processor usage, "Strømforbruk" = Power usage) I suppose reducing power usage is important in general to Techsmith as well..

Spotify is nothing more than a web based music streaming service is it not? I don't use it so I don't know for sure?It doesn't require a lot of CPU power to essentially surf the website for music, and listen to it.

Camtasia is a video editing software. Processing frames per second and a host of other things while playing back audio. That takes more CPU power.

Even windows media player uses between 2% to over 10% of my CPU when playing a music track.And I have a high end i-7 processor.

Spotify is a klient installed on desktop, with streaming MP3's in differenct quality modes, from a sentral database located somewhere on internet.

Are you playing music or video in Windows Media Player in figure - MP3/WAV or MP4/AVI?

The difference is most likely that players optimize the audio file when loaded for playback.

Camtasia doesn't optimize the audio file in editing. You want the full quality/data.
Optimization is done when rendering out the project.

Actually, Windows media player is a resource Hog for some reason.

Classic media player can play the same "music/song" at a CPU usage of less than 1%.
Windows is running between 2% and 10%. That's quite a difference.

My point was a a video editor is more than a media player.Playing a file isn't it's sole purpose.It's handling/analyzing the information in the file from an editing perspective. So it's playing the file and thinking about things at the same time.That will/should always require more CPU power.

Windows media player is actually obsolete.Has been for quite some time. I got used to it's functionality and like it. Considering what I've just learned.I might retire it.

Windows Groove music is consuming 0.3 % to play the same file.

Premiere Pro consumes around 5%. Which is much better than Camtasia.No surprises here. But much higher than my other media players.

Why does Premiere Pro consume much less power than Camtasia then, if that’s what you wrote? Surprise to me if so..

So Trond,

As I was out cutting grass  I decided I needed to run a new set of tests. I ran some before I went outside, but more than one of my programs didn't like the file I was working with.

If short, Camtasia and TechSmith products are unpredictable/inconsistent.Meaning you never know what kind of performance you will get out of a program, from one version or update to the next.
44,100 Hz and 16 bit .wav has been Camtasia's favorite codec for years. If you extract the contents of a .trec file, you'll find the audio tracks are recorded with that codec and settings.
So I converted a music track to those settings.Because I wanted to Give Camtasia a good shot at doing well in these tests.
Rather than type out all the information I amassed, I took screen shots to...
A. Show my work.
B. Save myself some typing.

Heres Camtasia 2019 playing that audio file, with Task Manager running.

The CPU averaged 7 to 10% usage.

Camtasia 8 did much better. At 3 to 4% on average.


Camtasia 9 ran around 4+ to 5+%.


So the older versions are processing audio better than 2019.

I got to looking closer, and 2019 starts eating into CPU usage as soon as I place media in the clip bin.With nothing on the timeline. Up to 3%  CPU usage. I will probably open a ticket with tech support tomorrow.

Subtract that errant usage of the CPU and you would have a better playback percentage.Still a little high, but better. It would come close to mimicking Cam 9's numbers.
That's what I meant by unpredictable/inconsistent. Its why I wasn't surprised Premiere Pro had better numbers than 2019.

So, Premiere Pro CC 2019. Ran from 4 to 6% on average. So technically, Camtasia 8 is the best one.But under the right conditions, a 32 bit program is faster than a 64 bit program. I suspect that's whats occurred here?


Adobes Premiere Elements 2018. 5 to 6% On average.


Heres a fun one. Hit Film Express "Free Version of Program" 20 to 24% Ouch.


So if you've got that much draw on the CPU, just to hear the audio playing.That's going to effect overall performance much more than these other programs.
Hit Film is a true 3-D editor. This may explain some of the high demand.

Hit Film Pro 2018. 7 to 10%. Much better, but still the highest numbers of all programs so far. Looks like the free version of the program is also lacking some performance. I didn't check it for updates. It might be a glitch.Overall, a good stable program.


 The lowest numbers of the day.Corel Video Studio 2019. 2 to 4%. This I did not expect.



After Effects is a vector based 3-d composition program. It's always been a dog as a result. And probably shouldn't be included in the test. However, 15 to 18%. But this I expected. Curiosity got the better of me.


Same with Crazy Talk Animator 3. Another 3-D, Vector objects and Characters. A CPU hog as well.
18 to 20+%


Media Players:::
Windows Media Player. Another dog, and it's not even program.Just a media player. 
6 to 9%.


ACG media player. The graphics in the player must eat up resources. I didn't bother shutting them off. TO much testing at this point.I don't typically use the player. I've seen enough but want to complete a couple more. 2 to 4%


Media Player Classic. Less than 0.5%


Windows Groove Music player. Less than 0.5%


Bottom line, listening to music requires little resources. Unless you run antiquated a Windows media player , which I installed because I like it. But now, I think I understand why Microsoft dumped it.

Any editing program should/will require more resources to playback an audio file than a media player or streaming service. Aside from  Windows media player that is {:>)

That's my observations,Joe
