Magix AVC render options questions
Hello all,
I was wondering how some of the customizable settings in Magix AVC/AAC MP4 work. I hope you can clear up some of my confusion! I am using this for the purposes of uploading 1440p60fps youtube videos.
VIDEO
-Number of Reference Frames. (I don’t think I understand the difference between reference frames, b frames, and keyframes)-Preset: Default, High Performance, High Quality, Low Latency -Default, Low Latency -High Performance, Low Latency -High Quality. (Not sure when it’s appropriate to choose any of those settings)
-RC Mode: VBR, CBR, Constant QP mode, VBR -high quality, CBR -high quality, low delay CBR -high quality. (Is this the recording mode? If I recorded using CQP, should I choose CQP here?)
NVENC Encoder vs Mainconcept: I heard NVENC speeds up the rendering, but may leave artifacts. Is this true?
Thank you all! 🙂

No, and it doesn’t answer my questions.
I am asking so I can have a better understanding of these parameters.

I was not answering your questions!
I was pointing out to you, an easier rendering alternative without the drama…… Your choice!Steve Rhoden (Cow Leader)

Although discussing x264 mainly, the above link does cover b frames, ref frames and much more.
I’m no expert but as I understand it low latency is more used/required for streaming.
The defaults in Magix are probably ok. Vbr HQ is what I choose in Nvenc.
2 ref frames and maybe 3/4 b frames in x264, it all depends of course on so many things, sometimes conflicting, do you want high quality, low file size etc, choosing one can conflict with another. Google it.
Steve was pointing to that usage of x264 within Magix because if you install it then you get to play with so many many different settings.
