Blurry images and videos when they are larger than 2048 pixels

I already reported this issue to your technical support and they confirmed the issue but I would like to describe the issue here also.

So...Camtasia Studio 8 is unable to display correctly any image larger than 2048 pixels (width or height, it doesn't matter). In fact, Camtasia seems to resample any larger image to 2048 pixels.
I have done such sharpness test to see exactly what Camtasia Studio 8 is doing:
-you can download the zipped project here (67,8KB)
-or you can try those images:
2048x64
2064x64
2080x64
2112x64
2304x64
2560x64
2816x64
3072x64
Of course, those images need to be scaled at 100% under visual properties
Here the result:

So you can see, larger is the image, and more blurry is the result...

Now, about videos...When version 8.0 was released, I was able to edit dual screens video (3360x1200 pixels) preserving the video sharpness but since version 8.0.1, Camtasia Studio is resampling any video larger than 2048 pixels to this last dimension. So it is possible to record 27" monitor using 2560 x 1440 pixels but it is impossible when editing to preserve the sharpness of the recording even for usual resolution output (1280x720). I am talking about video scaled at 100% under visual properties of course. Look at these screenshots (Camtasia 8.0.1 or 8.0.2) from this zipped project (1,42MB):



Larger is the video, and more blurry is the result...

So, I have done again a sharpness test you can try here (88,4KB):
and here is the result in Camtasia Studio 8.0.0 (no issue)


and now the result under Camtasia Studio 8.0.1 or 8.0.2


I hope you will fix that quickly, especially when it worked under version 8.0.0

Any news about this issue?
I mean, can I expect a fix in the future?

As >2048 pixels video worked with version 8.0, I suppose a bug has been introduced in the following versions but what about the callouts size limitation? Is it a bug or a technical limitation? I don't care about accurate preview and I can understand you are limited by 2048x2048 texture in the preview....but it is strange the limitation is there when I need to produce a video...

For now, I can't unveil an image moving it from right to left when using 1080p output because the image needs to be limited to 2048 pixels...so I can unveil 2048-1920=128 pixels only before the image becomes blurry. That's a terrible limitation!

I'm having the same problem too. 4864x1080 video, looks like garbage. If I extract an AVI file it looks OK but not within Camtasia 8.0.2

And of course without cursor animations which really stinks! I am going to downgrade to 8.0.0 to see if that works. It seems to be a video card issue because in my other software I have to turn OpenGL rendering off.

I just installed version 8.0.0 and got a run time error when dropping the high-res video into the timeline. HOWEVER, changing GPU acceleration to OFF and restarting Camtasia Studio 8 allowed me to drop it in with no problem! And it's sharp, just like Mickael A said it would be.

I hope Techsmith fixes this new problem. If you can edit something without it crashing but it looks like garbage what's the point?
