NotEnoughAV1Encodes VS digital_video_introduction

I think notenoughav1encoders is another one but I had only just remembered that one. Might be worth a check out though

Tools like NEav1e (https://github.com/Alkl58/NotEnoughAV1Encodes/releases) will do a better job with AOMEnc encoding, maintaining a better quality and efficient CPU use. However, it may require a lot of disk space for encoding (depending on your chosen encoding configuration).

Handbrake has AV1 options in the nightly releases. There are lots of encoders that wrap FFmpeg into a GUI such as Fastflix, nmkoder, qencoder, or Not Enough AV1 Encoders.

The answer is in this log which was made by this program for anyone interrested https://github.com/Alkl58/NotEnoughAV1Encodes :

It's good and getting gooder.

Just give it a try using https://github.com/Alkl58/NotEnoughAV1Encodes or whatever, svt-6 is fairly quick.

maybe you can try this https://github.com/Alkl58/NotEnoughAV1Encodes. Discovered when i read about AV1. So dont know it good or not.

There's a great introduction to video tech, including codecs, at https://github.com/leandromoreira/digital_video_introduction

A couple of AV centric scenarios I'd explore: - Set up two speakers fed with a mono signal, flip the phase on one and have students move around the area. From this introduce constructive and destructive interference and some basic acoustics. - Using an oscilloscope (or just prepped graphics) show a sine wave on an unbalanced line, how this is paired with an inverted copy of itself on a balanced line, and how this works to cancel transmission noise. - With an analogue signal now pictured, introduce analogue to digital conversion and what sample rate and bit depth mean. From this you can also start to introduce why gain staging is important in both pure analogue systems and those where you're bouncing between analogue and digital domains. - Introduce video: colour channels, different ways of representing colour and some (very surface level) compression basics like chroma subsampling. Really good resource for that here. - Introduce base patterns for getting any signals arounds: dedicated circuits (analogue audio, HDMI video, RS-232 control, logic IO) and network based (again for audio, video, and control). Dive intro signal flow, how to read a schematic and where reasoning about each of these modes differs.

If you want to keep digging from there, get familiar with the compression on NVX, JPEG-XS, and how it behaves. intoPIX are the upstream vendor that do some of the NVX internals and have some great resources on that here: https://www.intopix.com/jpeg-xs. For a guide on all things digital video I also highly recommend https://github.com/leandromoreira/digital_video_introduction.

Edit: After finishing writing the comment, I realized that it was more technical than I intended, and assumes that the reader has a basic to medium understanding of video compression. If not, I recommend this writeup/tutorial of digital video, especially the section about frame types.

A good high-level breakdown of H.264: https://sidbala.com/h-264-is-magic/
