Hey there! I am doing research about Unreal Engine 5 and I’d love to receive help on this. I am completely new to using Unreal Engine 5’s rendering systems by myself, and I was tasked to do research on the difference between Movie Render Queue and the Legacy Render. Does anyone have any pointers or specifics that I can start off with?
Hello there @Shelf_Related, and welcome to UE!
Regarding the rendering systems, the short answer would be that “Legacy Render Movie” is the original tool, while “Movie Render Queue” is the replacement.
LRM was used in older versions of UE, it’s a screen recording function incorporated into Sequencer. Basically, it plays your sequence in the editor viewport, and takes a screenshot of every frame as fast as your system can process it. A simple approach, and effective for a quick draft or screen test, but very limited, since it depends on the scene’s realtime values. You will always get a bit of artifacting, flickering edges, and low quality shadows.
On the other hand, MRQ is the dedicated tool for rendering, with it’s own complex system, to setup a full rendering pipeline. Instead of real time, MRQ renders a single frame multiple times from different cameras and intervals, blending everything at the end, with high quality results. You can also apply different kinds of render passes, according to the needs of the project. It’s best used for final cinematic renders.
The community has a lot of documentation covering both features, I would suggest checking the articles below for further details:
