Recording VFX

I want to post recordings of my VFX online and use some of them in my portfolio. What is the best way to record VFX in Unreal? Any good tutorial videos? Software screen recorders that dont kill the quality?

For screen recording i usually use Nvidia Shadowplay (if you have Nvidia GPU) as you can tweak bitrate and resolution. For quick small recordings it works well. Otherwise for more control and possible for lossless recordings you can use Unreals Sequencer and setup cameras then record the sequnce out from there. Here you can also play around with screen percentage in post processing + render out in higher resolutions.
