Hey Bluesky! I’m Luc, a video compression researcher near Montreal. Coauthored AV1 and co-designed the dav1d decoder. Expect AV1 content, news, coding tricks, and memes. #AV1 #VideoCompression #OpenSource

Have we entered a new era of compression? 4 teams in #CLIC2025 early leaderboard beat VTM, not in PSNR, but in ELO and perceptual quality. VTM used to be the gold standard. That may no longer be true. This slide from Théo Ladune nails it. @clic-challenge.bsky.social #CLIC2025 #ImageCompression

If the decoder is the new bitstream, then gradient descent is the new encoder Models like COOL-CHIC and C3 don’t learn to represent the image, they learn what they can forget. Compression isn’t about saving pixels. It’s about sculpting away what won’t be misse

The “AV1 is a disaster” myth Here’s what’s actually true: - SVT-AV1 is fast, fully multithreaded and packed with SIMD. - It scales beautifully on modern CPUs. - It beats x264, x265, and VP9 in bitrate vs runtime. AV1 on CPU isn’t a disaster. It’s quietly winning.

Are generic codecs holding us back? We built walls of complexity but overfitted codecs are leaping right over those limits. What if the future of compression isn’t more versatility, but custom solutions tailored for each challenge? Are you ready to take off the training wheels?

Seeing the drama on LinkedIn concerning SQL, I couldn’t resist

just added this video to the dav1d playlist, short ~3min video on benchmarking AV1 on Android. Love the shoutout to dav1d for “optimizing all the subroutines into NEON assembly” and using “the latest and greatest” instructions. #AV1 #dav1d #videotech #opensource #androiddev

What if Canada had its own CDN? Digital sovereignty, “maîtres chez-nous” of the internet age. Serving local broadcasters, hosting national culture, and keeping our bits and our dollars at home. Sweden’s looking into it. France already did. Why should we depend on the US for everything? #never51

The real headline isn’t #HDR10+. It’s that #AV1 is about to become the most streamed codec at #Netflix "AV1-SDR is already the second most streamed codec at Netflix, behind H.264 [...] we expect the day is not far when AV1 will be the most streamed codec at Netflix" Quiet shift. Big milestone.

Just started on Bluesky and didn’t expect to feel welcomed so fast. Honored and grateful to be included in @timmerer.com's Video Tech Starter Pack. Excited to join this growing community of codec devs, streaming pros, and open-source folks. #VideoTech #AV1 #OpenSource go.bsky.app/KMv5Lid

Can you believe it? #dav1d is 6 years old. Over the years, I’ve compiled a playlist of talks and demos that trace its evolution. It’s a great way to learn about dav1d and watch it get faster, smarter and more efficient over the years. #AV1 #VideoCompression #OpenSource youtube.com/playlist?lis...

I’m new to Bluesky and it’s great to see there’s already a vibrant community of video tech folks here. This starter pack is a great way to dive it. thanks @timmerer.com for curating it.

Bending Spoons pulling an Elon at Brightcove. 198 laid off, two-thirds of the U.S. team. Monetizing encoding infra remains brutally hard. HEVC’s fractured licensing model slowed adoption, killed deals, and left a trail of failed bets in its wake. #TechLayoffs www.nbcboston.com/boston-busin...
