Rendering stuck on 100% Camtasia 9 on Windows 10

Trying to render a 9 minute screencast for my students. Stuck on 100% rendering, waiting for an hour did not work, so really stuck. Tried lower quality, lower resolution, different subdirectory, nothing helps. Wasted half my day today, can't have such inefficient process, got more to do. Anyone knows a solution? PC has a recent i5 processor, 16GB of RAM and plenty of hard disk space, is only a few months old and up to date with all updates.

So Dr F Wulfert,

When a project gets stuck rendering, that usually indicates some corruption in the project.

At what percentage the project gets stuck. Indicates where the corruption exists. In your case getting stuck at 100 percent makes the detective work relatively simple. If the problem is indeed corruption, we know it’s at the very end of the video.

Most of the time when a video gets stuck rendering, it’s at 67 percent or 23 percent etc. so pinpointing the location is slightly trickier.

That being said, considering that this video is only 9 minutes in duration. I would try rendering 97 or 98 percent of the video. See if it will render to completion without any problems. To do that, have the timeline zoomed out so you can see the entire project on the timeline. Use the red and green timeline indicator sliders to select 97 or 98 percent of the video. With the cursor hovering in the highlighted blue area, right click and select> produce timeline selection as. And see if you can produce the video.


If you can, you know the trouble exists in the remaining section of a video at the end.

 It would be a good idea to place a marker at that point in the timeline.

If you have a fade to black, or a fade transition on the end of the video. That may be the problem. You can try removing it and just producing that remaining section of the video. If it produces, you’ve probably found the problem.

If not, it could be the audio. Try cutting the video at that point “If Required”. And separating the audio from the video. Then, move it out of the way down the timeline somewhere. And try producing that small section of video. If it produces, then you know that audio is probably corrupt. And will have to be changed.

If that doesn’t work, If there is an image in that area, I think you get the drill.

That’s the key, one way or another, you have to isolate the corrupt part of the video and correct the problem. There’s really no magic bullet, just a little diligence to find the problem.

Regards, Joe

Tried in software mode only, no difference. Tried rendering only part of it, no luck either, even if I choose only tiny part.

Is the video a Camtasia Recording?
What About the audio, where did it come from. A laptop mic, blutooth,etc. Is there a MP3 audio track?
Can you post a screen shot of the timeline?

You can try separating the audio from the video if it's attached. Then, turn off the video track by clicking the eye ball.

If the video produces you know the the video itself is the problem.

And visa versa with the audio.

If it's not a Camtasia recording, and it's the video. Re-encoding it/converting it into another format is probably your only option.
It's not that uncommon to run into.

It's a straight forward Camtasia recording. Nothing fancy. It has to do with Camtasia itself, the media files are fine. Following up an instruction by the TechSmith technical help department. Involves fiddling around with regedit, which is not seen positively by our IT department  but needs must.

Interesting, If you get it fixed/tech supports technique fixes it.

If you could you post the fix for others benefit. It would be appreciated.
