Description Unknown 2016-10-25 21:22:36 UTC
User-Agent:       Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0

See video in URL field for details.

After I stablize a clip with vistab in the Project Bin, going into the Project Monitor to playback or work with editing in the Timeline shows distorted video. The video only shows on the top-half of the Project Monitor, and the image is squished. Placing the new .mlt stablized video clip in the timeline only shows in the top-right part of the screen.

Reproducible: Always

Steps to Reproduce:
1. Right-click on a video clip in Project Bin. Go to "Clip Jobs" > "Stablize (vistab)"
2. Wait for new stablized clip to be created in Project Bin.
3. Select the Project Monitor widget and begin playback, or start editing in the Timeline to highlight the Project Monitor widget.
Actual Results:  
Shows distorted video. The video only shows on the top-half of the Project Monitor, and the image is squished. Placing the new .mlt stablized video clip in the timeline only shows in the top-right part of the screen.

Expected Results:  
No distortion in video, stablized clip can be added to Timeline and it should look like it does in the Clip Monitor.

I'm marking this bug as "Major" not because of severity, but because the video stablization is a significant post-production feature, and to have the result of using it be a distorted view in the Project Monitor, it effectively renders editing impossible. This is a significant issue.

Please try with the actual Kdenlive version 18.08.1

VideoStab with right click on the clip (Videostab2) is deprecated. Use VidStab under the effects. Do you have the same problem?
