playback gets stuck

  • Updated 3 months ago
When my projects get complicated, playback often gets stuck for 30-60 seconds - playing a loop of about 1/5 sec at the cursor - and then recovering.  Might be associated with an apparent memory leak -- project balloons from 1 GB to 6 GB. 

I have twice submitted tickets for this and was told to avoid using remove color and behaviors.  But it seems like it might be a bug because it always gets stuck about 1/2 second before the end of a clip.  Has anyone else seen this behavior?  Using 9.3.  Tech support confirms same behavior on 2018.

video produced is fine, but editing is difficult because playback gets stuck frequently

most likely the playback issue is system or project-specific related

have you tried setting the editor's hardware acceleration to software only mode?

thanks for your reply.  hardware acceleration is disabled.  happens in every project when the project becomes sufficiently complex.  i7-4770 3.4 GHz, 8 GB ram, 64-bit Windows 7

just a guess here, but using Win 7 might be the issue?

I use a modest i5 laptop, Win 10 Pro, with 8 GB RAM, good graphics card, 250 GB SSD; no issues like you describe even with very complex projects

perhaps try producing to AVI after some edits, which will simplify the project file; use the AVI to continue editing; etc

Do you overclock your system? If you know how, turn off hyperthreading in your BIOS and repeat. How could that possibly help?

Google "errata intel 4770" and see what problems you can expect across the board. 170 plus uncorrectable chip level errors! I have a 4790K so I feel a lot of your pain, but I now know all the work arounds too.
Unfortunately TechSmith is 100% software coders who have 0% knowledge of modern hardware issues for which they have zero clues and can't account for. Sorry TS. The fix (if you dare). . . 

Have you opened up windows' performance monitor while rendering?. Setting up a 'user defined' PM is NOT a cake walk, but there's a great video on youtube, see: https://www.youtube.com/watch?v=eTu7OIkrMfY

This sounds like a cache collapse to an enormous degree and it can be Camtasia s/w caused.

thanks ed and kayakman, but tech support confirmed the same behavior on their computers using both 9.3 and 2018, so it might not by unique to my system  (not overclocked, but i'm clueless about hyperthreading)
