Summary0003123: Aliasing on preview and blur on render makes project unusable
DescriptionAll files in my project show in the timeline with severe aliasing/jagged edges - this occurs with clips under .PNG titles (like the one pictured) and also on clips alone, with no effects.
When I render sections of the timeline, video is blurred, titles are extremely blocky and incorrectly scaled.
The project was fine for two days of editing, both preview and export worked normally (strange title distortion notwithstanding - thaough that's another bug for another bug report!) but when I started color grading, all of my clips in the timeline became jagged/aliased. Clips when viewed in the clip monitor are fine (see pic)
I didn't knowlingly change anything, though I removed some proxy clips around the time everything went wrong.
At the same time I found that all clips/PNGs with the Pan and Zoom effect had their scale and location values quadrupled. (i.e. X position changed from 100>400, scale 110 percent to 440)
The project is utter chaos and has to be finished today - for lack of a better idea, I'm currently manually recreating my edit in another program. Better ideas very welcome!
Steps To ReproduceThis appears to be a project-specific problem - old projects are fine, other NLEs handle the same footage without errors, and this project shows the same errors on a fresh kdenlive install on another machine.
Additional InformationProject is 1080p 25fps, footage H264 (Canon 5D MkII).

(I don't know if this is actually an MLT issue or something completely different)

Can you attach the .kdenlive project file here so that I can have a look. Looks like rendering uses the proxy clips...

attached! thanks. (I managed to recreate my project in kdenlive from an earlier version - there has been no repeat of this behaviour in my current project - it's almost ready to export again.)
