Hi the problem as it relates to Davinci Resolve Lite flicking in the Time line and after your final render has to do with the frame rate settings.
Your original footage ( capture video ), has been exported from your NLE video editing software without the original frame rate ( fps ). If the original footage is 23.9fps, your export may have been exported incorrectly, maybe 30fps.
In Davinci Resolve in the configuration section 24fps is compatible with 23.9fps, you would not get in problem here with this floating point value.
Check your frame rate to verify it matches the original footage from the camera on a MAC or PC you can click on the video file and check both the original and the exported file or simply check it from the import section of your video editing software.
If not , customize the export to match the original video frame rate and export, you are good to go
