Yeap, that's what they were selling: bitrate reduction on any video without loss of quality. So if you chain Beamr>Beamr>Beamr..., you are compressing to a singularity, maybe even to a negative bitrate.
EDIT: Most of those wonder technology companies scams out few thousands of $ and disappear, I see this one succeeded in raising the few millions, now they have money to augment their wonders with new fata morganas and try to legitimize in some way, but for how long, time will tell (btw, not comparable, but DivX thing is still ongoing). Anyone member Theranos? Last edited by VoodooFX; 27th September 2021 at 17:31. |

Beamr is absolutely not nothing
I've tested their stuff and it's quite good. Of course you can't just chain it in a loop, that's not how it works. They actually started doing what you're talking about - essentially automated compressed domain transcoding - which wasn't super interesting to me. Then they integrated that IP in-loop with their own encoders (which they acquired from Vanguard). This is actually pretty awesome. Their Beamr 4x and Beamr 5x encoders are H.264 and H.265 respectively with special rate control methods ("CABR") based on their optimization metrics. I didn't have the time to do a thorough evaluation but the results are definitely impressive, especially in the OTT use case where you need to build an ABR encoding ladder and the effort involved to do anything more complex than a static ladder recipe is substantial. Being able to just use CABR and say "Spend up to this many bits per second but please use fewer where it makes sense" (kind of a better capped CRF) is pretty great. Their people are generally really great too. Their technology is not cheap, but if you're in the market for a paid H.264 (or H.265) encoder their stuff is _absolutely_ worth looking at (as is Ateme at least and probably others).

Beamr has encoder implementations (Beamr 4 for AVC, Beamr 5 for HEVC), and they have a patented compression technology that they have applied to still image compression as well as AVC, HEVC and other codecs (CABR). Their base encoders are very, very good. Their CABR technology works as advertised. If you haven't evaluated their encoders, I don't know why you would think you are qualified to comment on how they compare. Last edited by TomV; 28th September 2021 at 07:42. |

It's overpriced, but this is enterprise area where everything has huge markup. I'm more shocked by support fees and the way how slowly problems are fixed. This is a joke, real joke.
At least in terms of reliability it sort of works. In the same time any custom made cluster system running ffmpeg (x264/5) on few machines can easily be as reliable. If you can do a bit of any scripting (Python etc.) then Vantage is a waste of money. Btw... anyone has Manzanita muxer license to sell? Last edited by kolak; 28th September 2021 at 22:17. |

Yeah, Beamr is definitely a lot of something! Some people may be thinking of their original business model and technology where they'd take an input file and retroactively apply an advanced flavor of CRF to reduce bitrate where it can be without reducing psychovisual quality significantly.
But then Beamr bought Vanguard a traditional (and very good) encoder company, and integrated their psychovisual tech in with the Vanguard encoders. So no second pass reduction involved, just a more psychovisually tuned encoder. |
