Crossfade from/into group

I'm having the same problem like described in this thread. I would have answered to this topic, but it's closed (why?).

https://feedback.techsmith.com/techsmith/topics/_fade_transition_issue_in_camtasia_8

So I have a group which I want to fade into a "normal" media clip. This leads to black artefacts. There are two workarounds: Ungroup the events and deactivate "use trimmed content". Both are not good solutions.

I saw that this problem occurs for more than 6 years. In the thread Josh said:
It is not a permanent solution - but hopefully a temporary workaround.
When can I except this bug to be fixed if it's not a permanent solution?

Your link requires an Adobe player driver? is ".. get.adobe .. a true adobe site? So why do I have to download your potential virus to see your problem? Get outta here lukas.

If your referring to the screencast video and you don't have Adobe's Flash player installed.You have to install the flash player to view the video.

I ran into that a few months ago with an older screencast video created in flash format.
It isn't lukas or anyone playing with you.

So, after six years is pretty safe bet. That TechSmith has no priorities with regards to correcting this problem.
The standard duration of a cross fade transition is one second. It's my opinion you can shorten this to as much as half a second and it still looks pretty good. That being said.

You can place the group over the top of the next piece of media. Or vice versa whichever applies. Overlap them by one second to 1/2 a second. Whichever seems appropriate for the situation.

Then, apply a fade in animation using opacity to the lower media.
And apply a fade out animation to the upper media. This is all a crossfade transition is in the first place.

The only way this trips you up is if there's audio overlapping as well. That's why I brought up shortening the duration to half a second. I found it's quite rare you're actually speaking right up until the last fraction of a second that you apply a cut to a clip. Or that you start speaking the moment you start recording.
If you're applying music to a clip that's a second track and you simply move it down the line.

Hi Joe,

thanks a lot for your detailed answer.

Yes, I mostly do screencasts when working with a music software so there's often music or effects to be crassfaded. So I need to automate the audio manually.

Then, apply a fade in animation using opacity to the lower media.
And apply a fade out animation to the upper media. This is all a crossfade transition is in the first place.
Hmm. Yes, it would be a workaround to use an animation with opacity instead of the transition. But wouldn't it be in fact just the upper media that should get the opacity automation to get what I want? If the lower media gets the animation as well, this would mean that it would fade from black to itself (whereas the upper media fades into the lower media as it should)? Not quite sure which of both is the expected behaviour (although the difference shouldn't be that big).

And nevertheless I think an editing software like Camtasia should be able to do proper transitions between groups.

Best, Lukas

Actually no, because you see. If the lower media is at 100 percent opacity while the upper media is fading out. This is not a crossfade.
The lower media is the dominating image throughout the effect and they don't mesh together as a nice smooth transition.

But you are correct the Camtasia should be able to do proper transitions between groups. As I stated earlier, after six years of being aware of this issue and not correcting it. I don't believe there going to.

No. This is a really special case. What you're doing here is rendering a frame of the whole video including the background. What if your background is a video as well or contains animations? This is not an universal solution since you can't export a frame of an group only. Thanks though!

sorry the method will not work for you

but you can save a frame of just an individual group, if that will help here

Perhaps I'm not understanding the problem, but can't you use SnagIt or a similar tool to grab a screen shot? You can then do whatever you want with the static image.

isolate the group on the timeline, then save the appropriate frame

I simply select/copy/go-to-end-of-project/paste, then pick&copy frame; after frame is saved, delete the displaced group

Sorry...but... okay, forget it. Thanks for your help. But you really don't get the problem.

So Brian Nystrom, the way I see it Lucas is talking about a group that contains transparency.

So this is another one of those situations where the workarounds can become too complex to be practical.

Because he’s mentioned transparency in his posting. Now, depending on the complexity of the image. Because Camtasia is incapable of saving an image with a transparent background. Removing that transparent background in another program could be relatively simple, or painstaking.

You can even try remove a color in Camtasia, but it's pretty ineffective if you're trying to use it around text or anything complex whatsoever.

Either way. The depth of the workaround is getting pretty complex overall. Once you start introducing all these levels to complete the task. After all were talking about applying a simple transition. Not creating a complex animation.

So all of a sudden, you’re talking about spending anywhere from a few minutes, to God only knows how much time to get to where you’re going. For an operation that should take you approximately one or two seconds.

This is just another perfect example of what I hate about workarounds. There’s usually plenty of workarounds suggested here in the user forums. But year after year no fix for a glaring defect in the software. How can there be any justification for a six-year plus bug in the software? With no foreseeable fix coming down the road?

Regards, Joe

Thanks for helping out Joe Morgan. Couldn't have expressed it better.

It doesn't matter if it's a shape with opacity (!= 100%) or just a shape with rounded corners. There are plenty of examples where it won't work to just make a screenshot in front of a black background.

I too believe a specific example would be helpful here; otherwise, I don't find a problem with transparent background stuff within a group with transitions

furthermore, if the grouped transitioned items are smaller dimensions than video on track 1, there is no need to fool with saved frames

I tested with a simple example project where 2 small size MP4 s with their own groups are transitioned over top another full-canvas-size MP4; everything seemed to work fine in the resulting production ...

however, if there are specific issues that have so far evaded me, then I demur ...

Here's a video of my reply:
https://www.screencast.com/t/XLDbu2lYxDl

time 0:00 - 2:00: 
- reproduce the problem in Camtasia 9 
- unchecking "Use Trimmed Content in Transition" seems to fix the problem
- lukas doesn't like this solution, but I'm not sure why

time 2:00 - end:
- maybe the problem is that the frame that's fading in is "frozen", and lukas wants the video to start playing as it's fading in
  - explore how to to this with groups
  
I hope this helps! Sorry for rambling!
