Hi All. I want to join the rant.
May 29, 2021 and the video sources are playing much faster than the exported video footage.
Some important notes:
- We are using the same FPS both for the level sequencer, child sequencers and all the video tracks - 24fps
- We CANNOT use the technique proposed above according to which we should convert our videos to sequence of images. Not every app made with UE4 is a game and not all the video use cases contains short videos. We are using UE4 for cinematic editing and we put dozens of video footages into sequencers which can be manipulated by users in runtime.
- Another pretty “weird” thing is happing when rendering videos via the Render Queue and enabling AA. In this case UE spits all the intermediate frames used for multi-sampling into the output, which makes the resulting image sequence pretty useless to transcode into video files.
To summarize:
Dear Epic, you put substantial efforts (which is much appreciated)to push UE4 usage into non gaming industries, especially into video /cinematic production. Please take care of these bugs as those quickly become deal breaker for anyone who is trying to use the cinematic features of the engine professionally. We also encounter inconsistent and buggy behavior of the level sequencer, especially when using spawnable actors. Recently we stopped using spawnable actors as we could not resolve bugs like invalid transforms of the actors /actor disappearance, which were happening sporadically. Also filed several bugs related to these anomalies.
Our current feel as someone who is heavily using sequencer and other cinematic systems of the engine is that it is all in a very raw state and there is still a lot of work to be done to get it stable for commercial usage.
If anybody from Epic’s staff would like to get in touch and learn about our challenges and issues we have, here is the contact email: info at codeartworks.com
