[Bug 1532574] [NEW] wavy edges zoom

 

Public bug reported:

I have a picture that I want to zoom in on during the video.  I use the
properties for the clip and select Zoom 75% to 100%.  It works, but the
rendered video is 'sloppy' for lack of a better word.

As the image resizes the edges of it are all wavy and it just looks
clunky.

The picture is a JPG.  I have tried exporting the video as MOV, MP4, and
Ogg using the Medium and High settings.  I also tried to select the
HD720 59.94 fps format.  Every combination is the same.  The video
exports fine and generally is good, but I cannot use the zoom because it
does not look nice.

Note that I do the same thing through Premiere Elements 12 on the same
hardware (dual boot) and it renders smoothly so it cannot be a hardware
performance problem.

Ubuntu 14.04 LTS
OpenShot 1.4.3
64-bit AMD Athlon 4600+
