I have the new 2019 version of Camtasia and the audio sync issues are just as bad if not worse.

I have the new 2019 version of Camtasia and the audio sync issue have not been resolved as promised in other threads.  I just recorded a 45 minute video where the audio started out in sync and by the end of the video it was out of sync by several seconds.  Really frustrating. Do you have a solution yet?

That's not the only issue with the not so great new version.

 The timeline lag I get is outrageous.

The new version (2019) is really a disappointment.

I have only played with 2019 for a short bit but here is a vid with just a few images on the timeline.

Take note of when the playhead hit the second and third image.

I have have done a reinstall and played a little bit with the setting like the driver options but at this point  really no change makes a difference.

 I have also put a video (recorded or exported in) but not done much testing but there is still some lag evident also.

That is weird. Can you re-render that while monitoring your hardware? [Task Manager], [Performance] tab.

Dubie, would you be willing to share that project with me? b[dot]andrus[at]techsmith[dot]com. I'd like to hand it over to the team that works on that area of the product. Also knowing your system setup would be helpful.

Best,

I’ve experienced the same thing. I just figured it was rendering in the background. If I get too many images on the timeline the whole thing crashes I have to rebuild.

I never saved it as a project as I was just checking things out.
I have since uninstalled 2019 for now.

From what I could determine is that large images caused the timeline lag.

Looking through the release notes one of the fixes I noticed was the issue of performance scaling large images down.



The same images I used in my example vid above worked without a issue in Camtasia 2018.

I'm thinking that what ever you did broke it in my case and still needs some work but thats just a guess.

cknox, Joe, Dubie - There is NO magic elixirs here. Watch a TV show, a movie. What is the max length of any one camera/voice recording? Everyone is 10-30 seconds - at MOST. It is worst, if audio is compressed.
Video and Audio are night and day. One proceeds at X speed, the other at Y. Period. TS can't fix something that has been true since talkies.

I've got a 2560 x 1440  3 hour 51GB Nvidia ShadowPlay recording.
The audios in perfect sync throughout.
If Nvidia can do it??????????

Yeah but I shouldn’t have to slip and slide the audio to match the video on every shot from the same clip. I’ve been in the video production business my entire life and I’ve never experienced lag like this on a regular basis. I don’t have this problem with Premier Pro no matter how long the clip is. One of the things I love about Camtasia is the ease of doing graphics and lower thirds. For that it’s actually faster.

cknox,
I agree, this is not normal.

For me, the sync issue started in version 2018 and now rolled over into version 2019.  I have to resort to slip and slide techniques or go back to Camtasia 2.
Never had this issue in Camtasia 2.

I'm not experiencing any of the delays you are Dubie.

I just placed 7.......6,000 x 4,000 pixel jpegs on the timeline and applied zoom in and out animations very close together in a 4K project. The timeline indicator skipped a beat but didn't falter on the first image.But that was the only hiccup.

Can you render that to screencast or an MP4 on the cloud?

for what it's worth ...

I regularly work with Camtasia 2019 projects [1920x1080] that have 500 JPGs [1620x1080] on the timeline; in some cases, there are 1000 JPGs on the timeline

on my modest i5 Lenovo laptop, I am not seeing any problems like described above, UNLESS there are also a lots of markers in the project [like 500], AND the marker flags are displayed; then the timeline becomes sluggish, and edit actions take a while to complete; if marker flags are not being displayed, then no problems

and, productions seem unaffected regardless

I created a timeline playback demo for ya Ed , complete with project settings info, media info,etc.

It's a 2K video, you should click the Vimeo link on the video and watch it in full screen.
