render problem #330

Closed shudct closed 4 years ago

shudct commented 4 years ago

I have tested some simple compositions as followed. But some strange problems have appeared.

  1. when rendering shapes, it has black edges, however in AE file is not contained.
  2. it seems that the shapes with opacity is not support?
  3. when rendering images, especially the image moved or zoomed in/out, the texture is incoherently if you concat them to a video and has some color blocks.

hope for your reply! thanks~

hi, I wonder if any solution for the above problem or have you discover the reason.

smohantty commented 4 years ago

Hi @shudct , I tested the generated json file from the resource you have provided and tested it in http://rlottie.com/ as well as the generated GIF file using the sample application lottie2gif provided with source . I don't see any problem with the white background . data json

As the layer above Red circle is not clipped to the circle boundary .. if the background is not white (maybe off white ) you can see those borders . you can easily replicate that in rlottie.com by changing the background color.

Hope this helps

thanks again, I have found the problem. By the way, I test the simple transforms, like shift and scale for images, the pixel of render result is a bit shaking and dismal.

pos scale the aep file is above.

Hope for your advice. Thanks again.

@shudct , I can't open image.aep because of the old AE . could you please attach the lower version AEP file.

Currently we are using simple liner interpolation for image resize thats why the scaling is not that smooth. need to add Bilinear interpolation for smooth scaling.

shudct commented 4 years ago

Thanks for your reply. By the way, could you tell me which script I can modify to achieve smooth scaling. Thanks again!

Created another issue ticket for bilinear interpolation support. https://github.com/Samsung/rlottie/issues/346
