Videos or images wider than 2048 pixels is scaled (up or down) after being resampled to 2048 pixels.
I opened this thread 3 months ago about this issue:
Blurry images and videos when they are larger than 2048 pixels
You need to know that Camtasia Studio 8.0 didn't get this limitation concerning videos size as this issue has been introduced by version 8.0.1 and 8.0.2
I reported this problem also but I am not sure if it is a normal behavior or if it is a bug...
Sorry you are having trouble - and thanks for posting here. I can't speak to why you are seeing major differences from CS7 to CS8 (hopefully someone else will shortly), but I did want to chime in on the downscaling.
Have you tried recording instead at 1280 x 720? I have had much better results recording/editing at 1:1 rather than downscaling. In fact, I always record on my smaller (laptop) monitor to limit - if not eliminate - downscaling.
Josh: Thanks for the reply! Recording it that small is just not feasible either, as I work with large scale images using Photoshop, and need the UI space as well for the palettes, full screening doesn't work in a small window like that and I need that for my workflow to browse through the image more efficiently. The thing is, I don't really mind that it's a little blurry when it's downscaled, but when I zoom right up to 100%, there should be no blurry *at all* -- it's 100%. So what I think the latest version of CS8 is doing, is that it's scaling the entire image down, then scaling it back up to 100%, which is wrong in the math, it should be concatenating the zooms and should be done one right after another, not one, rasterize, then two, zoom in again on rasterized image.
Catmasia 7 didn't have this issue, so Camtasia 8 shouldn't as well (well the latest version that is) Do we know if anyone at Techsmith has recognized this officially?
1) the issue you referenced a few months is still logged but other issues have been deemed higher priority so it hasn't been fixed yet.
2) All images will scale to 2048. This is an improvement over version 7 where they scaled to 1280. Im afraid this won't be changed soon as we are running into a limitation.
So I will wait for a fix but I am pleased by their honest reply.
I thought it was part of v8...I didn't have much experience with v7.
I am wondering if the capture is that much better in Captivate. I don't have the Windows version so I can't compare (I guess I could download the trial...it would be good to know if there is a difference).
Honestly, I am not that happy with the final outcome of my CS8 training videos because of the fuzziness but they are what they are so I just moved on. I am planning to do quite a bit more training so it would be good to know if there is a way to improve them.
The only thing I can tell you is that we try to produce our training videos at a comfortable compromise between bit rate and file size. It is important to us to keep the videos accessible to those with potentially slower internet speeds. We also scale/zoom to 100% whenever possible to eliminate any scaling whatsoever.
If you are seeing unwanted blurriness in your videos, have you tried increasing the quality slider at production? If you max it out, are you still seeing blurriness? A link to a screencast video or two might help us compare.
On a side note, this is all really helpful stuff. We are working hard to build training on video quality, aspect ratios, production settings, etc. So, thanks for posting.
When I recorded my screencasts on the Mac side, I recorded them all at 1280x720. I changed when I needed to start to record the taskbar at the bottom as part of the video.
I just recorded a screencast with Camtasia at 1280x720 (by resizing the application) and then exported at 1280x720 and it looks great.
Unfortunately, my monitor doesn't have a 1280x720 setting but it does have a 720p setting...I wonder if that will work?
Dave can you upload your small video and I can take a look at it and tell you how it appears on my monitor with the highest screen resolution setting? Thanks and have a great day.
As we found out earlier along with Mickael's 4 month old post, if you record anything higher than 2048, such as on my 30" monitor at 2560x1600, and then you resize it down to 1280x720, but then use the zoom feature to go back to 100%, the text and images are blurrier than expected. They shouldn't be, as Camtasia 7 handled this correctly. What Camtasia 8 is doing, is that it's scaling all video higher than 2048, down to 2048, which immediately is already a loss in resolution, but it shouldn't be doing this, it should be keeping a temporary scale of the 2560 video down to your selected video output size with the same aspect ratio, in my case, it was 1280x720 with black bars on the side, then as you use the Zoom feature, it should zoom back up to 100%, there fore a 1:1 representation of the video at a 1280x720 window, with no resizing. In CS8, you even see the original recorded video size of the image in your 1280x720 crop.
Think of the Smart Object feature in Photoshop, where you are allowed infinite transforms and resizes, while it still retains it's original resolution, so if you go smaller, then go bigger back to original size., it'll remember the original size, and won't lose resolution. This is what Camtasia 7 did before, but Camtasia 8 (v.01,.02.03) is not doing.
So currently, the solution is to get that temporary resize back into the Camtasia 8 engine, which was lost through updates.
Just to reiterate, when you use the ZOOM feature in Camtasia back down to 1:1 or 100% resolution then viewing that with any windowed resolution, such as 1280x720, despite any recorded resolution higher than that window, it should look perfectly crisp because there is no scaling...the only other issue is the codec, and I haven't seen the codec causing any blurring issue, in fact, Techsmith Codec 2 is amazing with really nice file size compression with quality, although it renders really really slow :( A plus and a minus.
Currently I am forced to record in V8 (so it doesn't crash on really long recordings) and edit in V7. Hardly ideal.
And yes - I really DO need it to be in high resolution. I have two monitors at 1920 * 1280 each, = 3840 by 1280 - two side by side concurrently timed recordings. By the time V8 has finished with it, it's unusable as evidence for a Courtroom - which is where is needs to be. None of the text is legible because of the scaling.
By any definition this is a bug that has been introduced that did not exist before.
