Problem: Camtasia 2020.2 keeps crashing during producing a mp4 video.
Each time the crashing was slightly different.
The worst case was end with the laptop screen became a completely back, and the windows complete crashed, you need to use laptop power key to launch the laptop again.
In most case, it was the retendering frozen at few percentages, then Camtasia simply crashed and closed.
Sometimes, it gave some error message before crashing and after the retendering was frozen at a few percentages.
the size of the Camtasia project is about 1.8GB, not extremely big.
I have tried my ways to try for producing mp4 video , they were:
1) Clear Re-install the Camtasia (uninstall, delete all Camtasia folder including folder in AppData and all Camtasia files before installation).
2) empty folder "Custom Production Presets 20.0" before loading the project
3) set the preference> Advanced > To "software only...."
4) change register "WPFUSoHard...." from 1 to 0
Non of the above actions can produce a mp4 video without crashing.
My laptop is a top end high performance station (Dell 5540, 16 GB RAM and a Nvidia video card), there is plenty storage space in the drive to save the mp4 file.
I am still waiting for the solution from TechSmith for this crashing, although Jason from TechSmith could produce a mp4 video for me by using the same project I have transfer to him, but I can not do it with my laptop locally.
Any comments and help are welcomed.
