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"

How to play a videofile reverse and unthinned?

TL;DR: I´m trying to find out which kind of videofile (format, codec, fps, etc) can be played backwards in UE4 unthinned.

Hey everyone,

I´m trying to setup a Blueprint that is able to play a certain videofile forward aswell as backwards. Playing the video forward is not a problem, but when it comes to playing the video backwards (playrate -2) it gets thinned (is dropping frames). As Epic states in their API (http://api.unrealengine.com/INT/Engine/MediaFramework/HowTo/ControllingPlayback/index.html) this behavior depends on the videofile itself. When I look in the info tab in the Media Player Asset it says, that the videofile does only support unthinned playback on a playrate from 0,0 to 3,0 (and thinned playback from -128,0 to 128,0). So this behavior is kind of what you´d have to expect. However, I couldn´t find anything about what kind of videofile can be played backwards unthinned. I´m currently using a videofile in MP4 format, at 30 FPS in the H.264 codec.

Any help would be appreciated. Thanks.
