Updated numbers for Eve-AV1 & Eve-VP9 are public! The last time they were updated was around 2019, so this should give a more relevant look at how they perform. It takes a lot to improve a mature video encoder, and I'm very impressed with the Eve lineup. I may be biased, though.

Someone casually dropped the Logic Bomb 💣 named tdarr

You can do DISTRIBUTED transcoding remuxing processing and automation of your Media Library

Now this is superbly interesting. All Sound Engineers have Massive, Massive media Libraries and I'm just talking about the audio

Then we have a Massive administrative system which accompanies the audio, because we need to know, what is where and Why, especially full analog audio that is still on Quarter inch Tape Reels, stacked in our large physical audio Archive.

We also have an Administration upon that, because we have carefully written down, which effect we used on which track, why and which parameters because everything is analog and nothing was possibly to be stored in a digital manner; that equipment didn't exist at all.

I have to check how long ago tdarr was developed, but this is a tool set that I needed 35 years ago!

Attention nerds! I just released a new version of my venerable video #transcoding tools:

github.com/lisamelton/video_tr

I've redesigned and rewritten this decade-old project for the modern era, with different behavior and incompatible APIs. Some old conveniences were removed but new features and flexibility were added. Please manage your expectations accordingly.

The king is dead, long live the queen! 🥰

Ha! Been struggling getting my #live #antenna #TV working right with #Jellyfin tonight so we could watch a live #countdown for #NYE tonight. Unfortunately Jellyfin doesn't have access to a GPU for #transcoding (#VM in a CPU-only #server). Using a dual-core #Protectli device for the antenna ingestion. Neither machine doing well transcoding. Finally figured it out by having #TVHeadend copy the video codec from the antenna and transcoding the audio to #AAC locally. Load is about 20% each, now. :D

If you're interested in video encoding at all, and you'd have a good time reading a video compression performance deep-dive with relevant metrics and a popular high efficiency video encoder, see my friend Trix's latest blog post on the Codec Wiki about SVT-AV1 v2.2's performance: wiki.x266.mov/blog/svt-av1-thi

Enjoy!

vt-enc: A VideoToolbox Encoding Script for macOS
github.com/gianni-rosato/vt-en

vt-enc is a bash script that simplifies the process of encoding videos with FFmpeg using Apple's VideoToolbox framework on macOS. It provides an easy-to-use command-line interface for encoding videos with various options, including codec selection, quality settings, and scaling.

HEVC is also now supported on Discord clients with hardware accelerated HEVC decode, so your output will be Discord compatible.

I have been using VRF for my Blu-Ray rips for a while now. Also like to control my bitrates.

ffmpeg -hwaccel auto -i input.mp4 -v:c hevc_nvenc -rc vbr -b:v 30M -c:a copy output.mkv

I find that lets my 4k HDR rips still look fantastic and during low movement scenes it can scale down and has plenty of room at the top for action / fast motion. Also looking for ideas / suggestions though.

I'm not sure who this is helpful too, but this seems worthy of sharing.

I'm finally getting back into working with video. I've been using ffmpeg to transcode video for years, and I put some notes together on h264 crf (constant quality) encoding. Which is what I use most of the time, though I'm starting to play with av1 a bit.

Hey everyone - wanted to announce a nice Aviator update that happens to coincide with an SVT-AV1-PSY update that we pushed just yesterday.

Aviator 0.5.1 has a couple new features, but chief among them is a new Subjective Tuning toggle for enabling encoder changes that improve visual quality at the expense of metrics. This is powered by SVT-AV1-PSY's new Tune 3 authored by Clybius; it adds subjectively motivated optimization to the existing Tune 2's great performance for an incredible balance of retaining fine detail in videos while still preventing blocking.

Here's a comparison encoded with Aviator (both 10-second videos were 7.5MB, down from the lossless source's 732.8 MB): slow.pics/c/tdrO5dY4

(the source is Netflix's `foodmarket` at 1080p)

If you prefer the smoother-looking, more appeal-oriented shot here, that is OK too - Subjective Tuning is toggleable!

Aviator 0.5.1 should be available on Flathub pretty soon. Enjoy!

Notes on H.265 Hardware Encoding

I’m starting to run low on disk space on my NAS, with Time Machine and VM snapshots taking up almost half of it. So I decided to do some cleanups, and after moving some non-critical stuff to my old NAS (which I use as offline storage) I started looking at my video folder.(...)
