Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UE 4.13 Media player plays texture too bright (with emissive color)

Upgrading my project from 4.12 to 4.13, the textures of my videos become way too bright. There is a huge difference, with the same parameters : alt text

Is it normal? It seems to me it's the media player that plays the video too brightly in UE4.13.

Product Version: UE 4.13

Can you copy/paste the contents of the Info tab in the MediaPlayer Editor?

Hmm... looks good. Can you share the video file? If you don't want to attach it here, you can email it to me: max.preussner@epicgames.com

Thanks!

OK I understood, there is a problem with the .avi compression. With .mpeg4 I don't have any problems, so I had to recompress all my avi in mpeg4 and it's all good. Strangelly, in UE 4.12 and previous, it was not a problem.

Can you send me the video anyway? I'd like to test it on my end. There seems to be a bug in WMF's YUV to RGB conversion for certain formats that results in incorrect brightness. I already have a list of known formats that use UE4's conversion instead. I may have to add your format as well.

Yes, I am sending you the video asap.

Can you share your video file with me so I can add it to my test suite? You're using a different encoder than OP.
