Since 2015, and the GTX 7xx series, Nvidia implemented a Hardware Encoder for H.264 in their cards. > encoding is required to stream and record > this relates to OUTPUTS and by definition consists into converting from UNCOMPRESSED VIDEO to COMPRESSED VIDEO > This requires a lot of processing power. everything is treated as UNCOMPRESSED VIDEO for best performance > processing is related to displaying inputs.

you have to understand the difference between 'processing' and 'encoding' This is explained in the vMix Knowledge Base !!! VMix is designed to work with Nvidia GTX or Quadro card to 'process' or 'render' ALL INPUTS (except those that can't be offloaded to GPUs, like NDI, some codec specific video files, old titles (not GT) and so on). Let's make it quick (hoping that you will cope with it to investigate more on your side)

We don't have time to repeat over and over the same information especially for those who don't take time to find the information they need by themselves. Want to make the right decision when upgrading my system for better quality, stability and ability.Įverything you ask for has been discussed many times in this forum and explained in the vMix videos on their YT channel. I would love to understand this signal path. So what happens here? As the video streams hit the PCIe bus from the capture card, it uses the GPU to encode the streams to H.264 and has to switch between the 6 streams (max inputs used so far) to encode them all at the same time? Then the CPU saves the files to the hard drive while sending the video to Vmix Before or After encoding? - to its graphic interface - and another recording stream is created that needs to be encoded as well and sent to the recording medium? 1 Graphics card.(gtx 1070) 1 CPU.(my system) Really want to understand this element of vmix processing better.ģ Encoders Max (Vmix) 8 Inputs (Blackmagic Quad 2). What I seek is the path, the physical paths that vmix uses to deal with video, including the graphics card, capture card, vmix and vmix encoders. When I ask this, I am not referring to the software component of how encoding works.
