DPI of PDFs being brought into Camtasia Studio

I'm making PDFs from SVGs in Inkscape (via save as) and my Inkscape document settings are 1920x1080. I have some options to change my dpi on save as and I've tried both 96 and 72.

But when I bring the resulting PDF into my media bin, the resolution says 1440x810 (which is the ration you'd get converting between 96 dpi and 72 dpi).

Are there any settings I'm missing? Does Camtasia have a size limit for PDF files?

Camtasia should run independent any monitor(s) we have.
I run it on two systems, one has 3 x 24" 1920 x 1200 monitors (96dpi), a second has 2 x 28"  3840 x 2160 monitors (154 dpi) -which is too tiny so I normally run both at 2560 x 1440 (102 dpi).

I think your dpi setting are intended for printed output. But again independent of monitors. I have hi-res pics that if I view them in a no-scaling viewer, I have to pan around to see everything. Or I can view them in a scalable viewer, and see everything in any screen size desired. But if I print the picture, I can choose any dpi from 1200 x 600 per inch down to ???

In the end, you have competing options for pics you use in Camtasia: Smaller dpi = grainier & smaller file or  higher dpi nicer looking but larger files. HTH

Video editors use pixel dimensions.
If you had a 1,000 dpi image at 1920 x 1080. Its still 1920 x 1080 video pixels.

DPI settings are used for printing purposes. A 1920 x 1080 image at 300dpi is much sharper than one at 72dpi.
When Printed.

If you scale up a 300dpi 1920 x 1080 image in a video editor to 400%.
It won't look any better than a 72 dpi 1920 x 1080 image scaled up to 400%.

I thought there might be some confusion! Here's a video showing the issue I'm having. I'm inclined to think it's a problem on Inkscape's end and how it's writing the PDF file.

Owen - Don't use PDF (i.e. as in PRINT document format). Try PNG !!

Yeah, I can always go the raster route, but if I'm making typical assets, it's really nice to use vectored images. (was ecstatic when Camtasia allowed PDFs, now just waiting for SVG support!)

Hey Owen,
I didn't realize you were working with PDFs I should have read your question more carefully.

I'm not familiar with Inkscape.
But I  use Adobe illustrator occasionally.

When I do export a PDF from illustrator. I stick to the default settings, changing nothing.
Have you tried creating a document at 1920 by 1080 without changing any of the default settings?
Then saving it without changing anything at all.

The image below is the default settings for illustrator version 2019. I have yet to update to illustrator 2020 as I let Adobe work out there bugs for at least six months before I upgrade. It seems to be the best way to keep me out of trouble.



When it comes right down to it.
When working with vector you could create them much smaller than 1920 by 1080.
I like creating custom steps for SnagIt's step tool. I'm going to use it as an example.

The PDF arrow shown below was created at 350 by 140 pixels overall. Yet I can scale it up as large as I want.
The project below is at 4K resolution.
The arrow has been scaled up to 5500+ percent. It still looks fantastic.



So yeah, see if you can use some default settings and come up with what you like.

Regards, Joe

Thanks, Joe - yeah, I'm pretty sure it's a problem with Inkscape writing the PDF file. I might try other vector apps just to verify. Being vectors, if I have to just manually scale the assets, so be it - was more just curious as to what was going on and whether I was missing something obvious.

Thanks for your feedback!

I think the final answer is that the hard-coded dpi of Inkscape is 96 whereas the hard-coded dpi of Camtasia is 72.
