Defish or Kdenlive broken...?

Sat Feb 08, 2014 10:47 pm
I'm working on a project where I want to defish the aerial footage I've shot with a GoPro HD Hero 3 Black Edition. In principle, this is easy, as all I need to do is applying the defish effect to my clips. The problem now is that Kdenlive often loads the project file in a way that albeit the defish parameters are shown correctly, the effect is applied with obviously broken parameters. For instance, I set the defish parameter to 750, and Kdenlive shows this parameter value after loading my project. However, the effect shown on the project monitor looks completely different. I just need to increase the parameter by one, and the effect pops back to normal result.

But what is worse: albeit the preview in the project monitor is correct, Kdenlive or rather MLT render the defish effect always with broken parameters. This makes MLT unusable.

My installation: Kdenlive from sunab svn repo;
frei0r 1.4.0+git20131020.10d8360f-0ubuntu0~sunab~saucy1
kdenlive 0.9.7+git20140202.645eed7a-0ubuntu0~sunab~saucy1
mlt 0.9.1+git20140207.4945fd34-0ubuntu0~sunab~saucy1

Okay so I found this old post of mine. As I had recently to defish a project, I gave my recent setup a try ... and it went okay: no more parameter mess, no more garbled frames or crashing MLT.

Current MLT is 0.9.9 (from git master), Kdenlive is 15.12.0 (actually 15.13 from git master).

Oh, those were the time... :)

Apropos: defishing a GoPro image shot in 2.7K I used these defish effect settings:

Amount: 670 (your mileage may vary, but you get a sensible ballpark number to start from)
Type: Equidistant
Scaling: Fill
Manual Scale: 500
Interpolator: Bicubic sharp (yess, for what else do I need an i7?!)
Aspect Type: Square
Manual Aspect: 500
