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"

What video codec for HiRES video with Alpha Layer?

We have an Unreal environment running on Windows and we need to use hires video (up to 4K) What codec is best used?

The video we want to play inside the engine has Alpha layers. For performance reasons we prefer to use a single file, but the video file formats that have an Alpha layer built in are limited. We can circumvent this by using a second video with an alpha channel. Either way, what video gives us the best performance?

H.264 mp4 gives us the resolution, but does not provide 100% smooth video. Any tips?

Product Version: UE 4.14
