What is the maximum editing resolution in Camtasia Studio 9?

In Camtasia Studio 8 the maximum editing resolution is 2048x2048 which simply isn't enough when i want to record my 3840x1080 dual monitor setup. Since Camtasia 9 still doesn't support 60fps (massive mistake there Techsmith) I wasn't going to upgrade until that was integrated, but if I can actually have editing dimensions high enough to edit my 3840x1080 videos at full resolution, that would also be a reason for me to upgrade.

I believe it is 4096x4096, but best to confirm with TechSmith tech support

The max dimension for editing is 4096x4096.

However, the max dimension for MP4 is a little smaller than that.  The upper limit on the H.264 encoding is level 5.1.  So the tl;dr version is that you can produce at 4K dimensions of 3840x2160 @30fps.

For a more detailed explanation of H.264 levels, read on :)

There's a table that lists the H.264 level constraints here:  https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels

The H.264 levels can be a little confusing if you haven't spent much time with the H.264 spec.  They specify max decoding constraints in macroblocks and macroblocks/sec.  A macroblock is simply a 16x16 area of pixels.  This means to figure out if your desired output meets the level constraints, you have to do a little math.

Given an output width and height, the macroblocks are calculated like this:
macroblocks = ceil( width/16 ) * ceil( height/16 )
The macroblocks/sec is simply macroblocks times the output framerate:
macroblocks/sec = macroblocks * framerate
Level 5.1 constraints from the above table:
Max Frame Dimension = 36,864 macroblocks
Max Decoding Speed = 983,040 macroblocks/sec

Armed with this information, here are a few examples that meet the level 5.1 constraints:
3,840×2,160@30 fps
4,096×2,048@30 fps
4,096×2,160@28 fps
4,096×2,304@26 fps

If you stick with 3840x2160 (4K dimensions) or less, you should be able to produce with Camtasia 9.0 up to 30 fps.

Hope this helps.

Thanks for the response. :) I suppose I'll be saving up £100 for the upgrade then.

I have a question according to this: When will Camtasia support 60fps or even more?

Im very happy for an increased resolution. But 60fps would make it shine :^) (for example 4k 60fps) <3

posts on this forum by TechSmith employees have indicated that 60FPS is being worked on, but would not be an included feature in the 1st release version on CS9

some posts have also indicated that working on a 4K 60FPS project will require a very powerful system
