Does anybody have any tips for importing lecture slides into Camtasia? Whenever I go to 'produce' my Camtasia lectures slides (imported as PNG files)- the video output quality is so terrible. Any tips for better quality output?

using CS8?

what dimensions are your PNG files?

what video format, and what dimensions are you producing to?

if source file, editing, and production dimensions are all the same, PNGs should give excellent results

try using the above settings, and do a custom production to MP4 with controller, and set quality to 70%, H264 to high

does that help?

Hi,

Yes, I'm using the latest version of Camtasia Studio. 

The dimensions I'm using for my PNG files are 10 inches (width) by 7.5 inches (height).  Should I be using a different size?

those dimensions are pretty small, unless viewing the video on small screen devices

can you obtain larger dimension PNGs?

as a test, you could set editing dimensions to 1000x750, and produce at that size to just MP4 without controller

play the resulting MP4 at full size [not full screen size]

how does it look?

I find it best to work with the largest sized [native resolution] images that will fit with your monitor's dimensions, and then edit and produce to those dimensions

you do not want to downsize or upsize because that will diminish quality in resulting video

I create my slides in Illustrator- so yes, it's definitely possible for me to use a large dimension size. What size should I be creating them in that's ideal for CamTasia Studio?

how big is your monitor?

I use a 1920x1080 monitor

depending on your image's aspect ratio, I'd create images that vertical size-wise, that match your monitor's vertical resolution

in my case, my project images are usually 1080 pix high

example: photos from by digital SLR are exported from Lightroom at 1620x1080, and used to make photo slide show music videos; editing dimensions are usually set to screen size [1920x1080], so I accept a small border on the sides [images are kept at native aspect of 1.5x1.0]; my productions use a video background color so the movie looks very pleasant when viewed in a browser

Mine is 1920 x 1080. Also, I find that the output colour is slightly different from my actual image colour. Any tips for resolving this?

create your PNGs at 1920x1080; follow instructions above for custom production; make sure you set H264 to high, quality to 70%

what browser are you viewing with?

I'm using Chrome- but not sure how that's relevant? It's the final video output, which I'm viewing with either VLC Media Player or Windows Media Player on my computer.

Also, how do I do the following: 

"do a custom production to MP4 with controller, and set quality to 70%, H264 to high"

watch using Chrome; launch using xxx_player.html, which is one of the produced files

FYI, early versions of some browsers have problems accurately displaying colors
