Image overlay zoom very poor quality
Hello,
When overlaying an image in my video, I am using the Video Processor opacity / zoom / location plugin to move my image over to the right in front of some video. When I use the zoom functionality to reduce the size of the picture, however, the quality of the image goes way down, it gets very pixelated and blurry. Is this normal? Example: https://imgur.com/Howmbrc It's a .PNG file, if that matters. |

I just had a look at this, and it seems there is some massive problem with Reaper image resize quality. I assuming that the fullscreen preview is the same as the full slow render, here is my very quick rough test:
https://www.learndigitalaudio.com/wp...om-quality.png Look at the top of the plane in the Reaper render, it is jagged and really bad looking. I have a horrible feeling we are seeing Nearest-neighbor interpolation, the lowest quality resize algo. If this is the case I am praying we can get at least Bicubic asap: https://en.wikipedia.org/wiki/Image_scaling Quote:

Did you turn the filter parameter to 1 (on)?
You can also use "image overlay" preset (and you'll probably have to enable the filter). This preset will allow you to use PNG which have transparent/alpha. |

with the filter parameter set to "on", overlay zooming results are still far from smooth. The same is true when zooming text overlays. I hope that these issue will get addressed soon.
