This was my actually posting requesting assistance but it's fixed, dunno how. details below

using camtasia 24 on a pc. recorded about 70 videos now all of a sudden the audio is lagging. i even separated it on a 20 min video and aligned it and a few mins later it's lagging again so this tells me that it lags more as video duration goes on. i recorded in logi capture and audio is aligned with video. im using a studio mic into a 286s processor and then into interface then into computer. audio/video is aligned in obs as well

Fixed:

i been fighting this issue for almost 2 weeks asking here was last resort ok so while typing this asking for help i tried obs and it was fine in there. then i imported the obs 2 min test video into camtasia and everything was still ok. then i left that video in camtasia and clicked record and recorded a 2 min video in camtasia and everything was fine. i closed camtasia, reopened it and did another 2 min test recording and everything is still fine.

so now i just started new project and new video trying to create a longer video as im typing this and talking in the video at same time and reading this post

ok it seems to be fine now, i even rendered it and its still fine any ideas? i changed no settings.
