Not "new", if the key factor for you is speed then it's the best, imo. And it's free (v1.2), I guess that v2 is even more faster.

100% lossless & best compression is important for me.

Digital cinema uses lossless JPEG2000. More recently, H.265 added a lossless mode as well. Acoording to a 2012 paper (http://www.apsipa.org/proceedings_2012/papers/252.pdf ) Motion JPEG 2000 (using wavelets) appears to be slightly better than H.265. JPEG-LS is not that far behind either.

HuffYUV and Lagarith are probably the best absolutely lossless codecs, you can compare their techniques. Although it's worth pointing out that just the way you transform the colour from RGB to YUV (or other colour formats) is a mathematically lossy process.

With 4K and more affordable SSD storage there has been a rise in the use of RAW-ish formats but they are largely proprietary.

But also most organisations don't want or need totally lossless, more visually lossless and that's why JPEG2000, JPEG-XS/XR and AVC-Ultra are very common formats for interchange in professional circles.

There is a big difference between 2:1 compression which you might get with something like Huffman tables and the 10:1 or better that you can get with accepting the output won't be pixel for pixel identical as the source.

I'm fine with it. 2070 is enough for now.

Any active lossless video codec with Adobe plugin support? (excluding MagicYUV & FFV1)

Then look at x265, because MagicYUV's compression ratio is weak.

Is x265 really lossless?

What means "really lossless" (or "not-really lossless")?

I heard that it is not 100% lossless and when converting the image quality is lost.

Mathematically lossless

Unlike visually lossless codecs, MagicYUV is mathematically lossless, meaning that the decompressed output is bit-by-bit identical to the original input.

This means there is no generation loss. You can re-compress the same clip over and over as many times as you want without quality degradation.
Above from previously link to its home site.

If using eg YV12 loaded into VirtualDub2 Full Processing mode,
and saving as compressed YUV then will go through conversion to RGB and then to YUV and then compressed.
So, there would be losses in colorspace conversions, but the compression itself is lossless.
[Full Processing, mode converts to RGB for Vdub processing/filtering]

Fast Recompress mode, will enter into negotiation between VDub and MagicYUV and come up with a strategy to avoid colorspace conversion, if possible.

Above how it used to be, there is new VD2 Normal Recompress, not sure how that is different.

If you don't compress as lossless then it's not lossless, if you compress as lossless then it's lossless.

What about AME (Adobe Media Encoder)? I always use it as my media converter with lots of plugins.

Sorry, no idea, I dont use it.
Also, I rarely use MagicYUV and only have the old free one that runs on XP.
[I usually use Ut_Video, and again only the old XP compatible one]

What lossless format compresses most of all, still YULS?
