Adobe Premiere Elements 14 / Choppy Video + Desynchronized Sound

[GUUUUUUUUUUUUUH]

Hi Everyone,

im having a Problem, while editing Videos, where the Picture will get chopped up at irregular intervals and the audio will get desynced.
It´s not due to rendering and the choppy Video persists even when i turn it into video file.

I´ve tried to adjust the Pre-Settings according to the Videos im using and re-installing.

I´ve also tried to contact support but unfortunately they don´t support Elemtents 14 anymore.

Has anybody had the same Issue and knows how to fix it?

Thanks a lot for reading!

What model of camcorder is your video coming from and what is the video's resolution and format?

If this is not camcorder video, it could be related to a variable frame rate in the file.

Don't know if this would work with 14 but I had the same type of issues with 18 and spent a couple of hours on the phone and chat before coming up with this fix that worked for me.

To fix the choppy sound and video: Edit - Preferences - Audio Hardware - Change Default Input to No Input. This took care of both. I still had video quality issues and was told that MTS files do not work well in Elements. To improve the video I had to export (Export and Share) to a folder as a mp4 then import back into Elements for editing. It is BS but I was told by customer care that Adobe knew the issue and was working on a fix?

that is simply untrue.  AVCHD or MTS files have been supported and work well since about version 10 or 11.
