Working with captured files outside Camtasia

  • Updated 3 months ago

I need 24fps screen captures. I'm not interested in using any of the features of Camtasia Studio other than screen capture, since we'll be editing in a different system. I don't want to export the files from Camtasia because it only works at 30/60fps and will pull the frame rate up to 30 by repeating frames.

In the recorder window, I can specify the captured file's frame rate at 24fps, So what I'd like to do is open that captured file directly in something like DaVinci Resolve (though I expect we'll need to convert it first, which is fine). The problem is that I can't open the AVI in anything. On Mac, Windows or Linux machines - In Resolve, it doesn't show up in the media browser (which typically indicates that it's a bad file), on the Mac, Quicktime Player says it's unable to open it, and on Windows Media Player it shows up as having "encountered an error" with the file. VLC just fails silently.

I'm using the free trial version right now - is it possible it's connected to that? Shouldn't I be able to open the captured file directly in any application that can work with the AVI? What format is the file captured to within the AVI container?

While I am unable to address or answer exactly why the AVI won't open in other editors, I do believe that there is nothing being done as a result of using Camtasia in evaluation mode that would cause it. The only real restriction is the time you have to use it and the fact that if you render videos with the trial, they have a watermark on them.

If you have the full version, are you able to open the raw AVI capture files in, say, Windows Media Player? If the watermark is applied on export from Camtasia, then that might explain why it's not opening for me.

I just tested by performing a brief recording in AVI format. I right-clicked and opened that AVI in Windows Media Player. Although, I didn't adjust the fps to 24. Lemme go try that and report back.

Okay, 24fps worked fine as well.

Thanks. So I'm guessing the trial version is in fact the limiting factor here. The watermark is probably inserted when you export the file. On the 24fps file, does Windows Media report what codec is being used?

AHA! That's the problem.

I didn't realize this is using a proprietary codec. I installed it on Windows, and now the files open up in Windows Media Player and VLC, but not in Resolve (Which isn't entirely surprising). Just need to figure out if it's worth it at this point to spend $250 for just the capture tool, since I'm also going to have to convert every video before it can be opened in our editing tool...

Thanks for your help!
