Blur raster effect does not work in exports #286

Open schuettec opened 2 years ago

schuettec commented 2 years ago

Hi got a problem with blur effect in one of my projects. I did a simple test project to reproduce the problem.

I got a rectangle with blur effect in front of a few shapes with outline displace. The blurry rectangle fades in and out quickly in the animation.

In some exports the fading is not rendered correctly. I found out this has something to do with export parameters. I tested with

My test series:

The dimension might have something to do with the problem. Could this be a bug in shader code or stuff?

Hey! Can you send a scene file?

schuettec commented 2 years ago

Doh! I forgot the attachment.... :) BlurTest.ev.zip

AlexKiryanov commented 2 years ago

This is the result I got. 180-220 frames. test.zip

schuettec commented 2 years ago

Hm for you it seems to work...the result looks different on my machine. How can this happen?

schuettec commented 2 years ago

Tested on two machines. I got this one: MyTest.zip

To be honest, I don't know why you have such a strange situation.

So I once again opened your file and rendered with standard settings. prew I counted out 250 frames. As a result, I got this video. untitled.zip

The question is, why do you use the bloor effect for such a purpose? Would you mind using a gradient? Or, if you need any special gradient, make it in a graphics editor and then import it into enve?

I used the blur effect because I got banding in the result export when using gradients. But in the end it makes no difference because the banding also occurs with blur effect.

I just thought it would be nice to have a working blur effect :)

I just thought it would be nice to have a working blur effect :) Yes, but there are bugs and it looks like they will not be fixed...

AlexKiryanov commented 2 years ago

Hello David! @dadoprom Please tell me, do you get the same bug? It works fine for me.

Hi, I already test your file, but it's fine in my laptop. I am rendering as MP4 with default setting. I am also test playing your rendered file. its fine, no banding. can you screen shot the video result ? I want to know it's look like.

schuettec commented 2 years ago

Hi, to be precise: The banding it not the actual problem. There is a little bit in the export. Here is the screenshot. But that's fine for me. MyTestPlaybackScreenshot

The main problem in my MP4 export is, that on my machine(s) I don't get a fading. It just flickering. An I can reproduce this on both of my linux machines. I will check this on windows asap.

schuettec commented 2 years ago

Yes, but there are bugs and it looks like they will not be fixed...

If so, this is totally ok.
