Here's my conversation all about FFmpeg, the legendary open-source software powering most video on the Internet. In the episode, I talk with Jean-Baptiste Kempf and Kieran Kunhya. JB is lead developer of VLC and Kieran is FFmpeg contributor, codec engineer, and the person behind the now-infamous FFmpeg account on X. VLC (VideoLAN), by the way, is also a legendary piece of open-source software: it's a video player that can open basically anything & has been downloaded over 6 billion times. I think both FFmpeg and VLC are two of the most important and impactful software systems ever created, both open source, and both created & maintained by volunteers: brilliant engineers from all walks of life. Thank you to everyone who contributed to FFmpeg and VLC, and in general to all engineers giving their heart & soul to building systems used by millions (or billions) of people, and often doing so not for money, status, or fame, but purely for the love of building great software and doing good for the world. Thank you to the builders! 🙏❤️ Shoutouts in this chat to John Carmack Andrej Karpathy Elon Musk Tim Sweeney and everyone who is a contributor & fan of open source!

VIDEO | As petrol and diesel prices go up by Rs 3 per litre each, a consumer at a fuel station in Mumbai says, "Petrol was already Rs 103, which was difficult for us. Now it has gone up by another Rs 3.13, making things even harder. Salaries are not increasing, but expenses keep rising. I have two children, and I need petrol daily for work and to take my family around. Even using 2 litres a day means Rs 200 to Rs 400 extra every month. Petrol is essential for work and family needs, so we have no choice, but this is wrong." (Full video available on PTI Videos -

RunwayML is not limited to 4sec! Here's how you can bypass the limitations 👇 Step 1: Generate your video with Runway Step 2: Get ffmpeg Step 3: Grab the last frame of your video using this command ffmpeg -sseof -3 -i [input_file_name.mp4] -update 1 -q:v 1 [output_file_name.jpg] Step 4 : Use the image output as the input for your next RunwayML generation Step 5: Stich them together in your favorite editing software Step 6: This is the most important step! Like, RT and follow for more good stuff, thanks! ♥️🤗 It's not perfect, but it's a start, I added 5 clips in total in the video below, just so you can see how it evolves over time. With a lot of generations eventually it can look decent for 2-3 clips. Voice by ElevenLabs Music and SFX by Epidemic Sound Sound mixing with Ableton

A Bengaluru youth recently demonstrated the power of AI when he used ChatGPT to negotiate an auto fare from Rs 200 to Rs 120, overcoming a language barrier. The student, who was a non-native Kannada speaker, turned to ChatGPT for help, prompting it to communicate with the auto driver in Kannada. Using the AI’s voice assistant, the conversation unfolded smoothly, with the driver initially agreeing to Rs 150 and finally settling on Rs 120. This innovative use of ChatGPT to navigate a real-world situation has gone viral, highlighting how AI can be used to simplify tasks and break down communication barriers in everyday life.

HERMES AGENT CAN CREATE VIDEOS. NOT WITH AN API CALL. IT WRITES THE CODE, RENDERS THE SCENES, AND STITCHES THEM INTO AN MP4. the video attached to this post was generated by Hermes Agent using manim-video skill. three bundled video skills most people skip: 1. MANIM VIDEO 3Blue1Brown-style animated explainers. algorithm visualizations, equation derivations, architecture diagrams, data stories. the pipeline: PLAN → CODE → RENDER → STITCH → AUDIO → REVIEW Hermes writes a plan.md with narrative arc and scene list. then codes a Python script with one class per scene. renders each scene through Manim CE. stitches clips with ffmpeg. adds voiceover if you want it. requirements: → Python 3.10+ → Manim Community Edition v0.20+ → LaTeX (texlive-full) → ffmpeg → no GPU needed draft quality: manim -ql production quality: manim -qh 2. HYPERFRAMES complement to manim-video. use manim for math and algorithms. use hyperframes for everything else: motion graphics, talking-head with captions, product tours, social overlays, shader transitions. HTML is the source of truth. GSAP timeline for animation. CSS for appearance. HyperFrames engine captures frame-by-frame and encodes to MP4 or WebM with ffmpeg. 3. KANBAN VIDEO ORCHESTRATOR this is the advanced play. a multi-agent video production pipeline backed by Hermes Kanban. it creates profiles for each video role. a director profile decomposes the project into kanban tasks. renderer profiles pick up scenes and produce them. the orchestrator decides which skill fits each scene: manim-video for math, hyperframes for motion graphics, p5js for generative art, blender-mcp for 3D, ascii-video for terminal aesthetics. one prompt. multiple agents. one final video. HOW TO USE: enable any of these: /skills search manim /skills search hyperframes /skills search video or ask directly: "create a 60-second explainer video about how the self-improvement loop works in Hermes Agent. use manim style. dark background, amber and teal accents." Hermes writes the plan, codes every scene, renders, stitches, and delivers an MP4. you review and publish. comment MANIM and I'll send you the exact prompt I used to generate the video in this post. full Hermes NIGHT MODE WORKFLOW 👇

THIS GUY ASKED FABLE TO MAKE A VIDEO ABOUT WHAT IT'S LIKE TO BE AI RIGHT BEFORE IT GOT TAKEN DOWN the prompt: "you can you use whatever resources you like, and python, to render a short video. can you put a more personal spin on it? it should be about what it's like to be you." that was it. just python and ffmpeg and a question about its own existence. 12 minutes later, around 90,000 tokens, it produced a finished video. coherent and edited, with its own take > it wrote the code, generated the visuals, and rendered the final cut on its own > no dedicated video model in the loop, just a language model reaching for python and ffmpeg > the result is competent enough that people genuinely got emotional watching it and then fable got pulled. this video is one of the last things it made before it went dark a model asked what it's like to be itself, answered in a video, and then disappeared. this sounds so sad

"I've spent $30K on a launch video, now you can make one with code." Here's my new episode with Bin Liu and Jake Moran, where they shared their 5-step playbook for using HyperFrames to make professional launch videos in Codex and Claude Code: 1. Gather video assets and create a frame.md 2. Create a storyboard.md with the scenes 3. Pull animations from the HyperFrames repo 4. Generate and review static frames 5. Build the video with HyperFrames Studio You can also start simple by using the built-in /website-to-video skill to one shot a launch video from any URL. HyperFrames is 100% free and I love how it democratizes video creation for everyone. 📌 Watch now: Thanks to our sponsors: Wispr Flow: 4x faster than typing with your voice Riverside: All-in-one AI studio for podcasts and video

Omg, this is such a hack for vibecoding mobile apps This is an image with a video on the top. The video is a character with no backround. I'm using: > Masko AI to generate the video > vibecode.dev to build the app In masko all you need to do is provide an image, and it will give you a video without a background. And then all you need to do is give it to vibecode.dev which is the best mobile app builder.

Consistent character with Hunyuan and Skyreel! 🎥✨ In collaboration with Kartel.ai .ai, we worked on a pipeline using ComfyUI with the Hunyuan & Skyreel models—both designed for video. We first captured him volumetrically, then trained a LoRA model directly on video data, allowing us to generate sequences where a person remains consistent across shots. The goal is to maintain identity and style over time, pushing the limits of AI-generated video. Excited to explore this further! 🔥 with J. Salvatore in main actor , thank you ! #AI #GenAI #ComfyUI #LoRA #VideoGeneration #Hunyuan #Skyreel

#WATCH | Delhi: Sanjay Kumar, Secretary, Department of School Education and Literacy, says, "The process that previously cost Rs 700 rupees, under which we provided you with a copy of your answer sheet, that fee has now been reduced to just Rs 100. Furthermore, the fee for validation, which previously stood at Rs 500, has also been brought down to Rs 100. So, for instance, if you wish to have the answer to a single question rechecked, you would need to pay Rs 225 rupees. However, if for any reason the re-evaluation process reveals that your marks have increased, we will refund the entire amount you paid back to you... We are more concerned about the well-being, welfare, and mental state of our children. Money is important, but it is not the priority in this particular matter..." He also says, "We will simply provide you with a copy of your answer sheet. By merely looking at the answer sheet, it will become evident how the marking was carried out. Once you review it, you may realise if there were instances where you should have been awarded higher marks. Since the answer sheets have already been scanned, I do not believe there is any need or any alternative method for a further re-examination."

In our VRChat integration, an extra feature we plan on working on is the ability to use Hyperbeam to share gameplay directly into video players with nearly no delay. Here is SonicFox using a test setup to showcase exactly that! (Thanks for testing it out!)

Today, all members of our negotiating team will already be in Ukraine, and I have scheduled a special meeting with them for tomorrow regarding our next steps and decisions. They will deliver a report on those aspects of the negotiations that should not be discussed over the phone. We will also define the further framework of our dialogue with the American side, with the Europeans, and with the Russian side. It is important that the Europeans were present in Switzerland. This is exactly how we intend to work going forward – to ensure that Europe’s positions are taken into account.

This is Candace Owens' playbook: Make outrageous claims - with no evidence - then shift the burden of proof onto others to disprove. When challenged, move the goalposts, play the victim and do everything to dodge having to actually back up your original claim with any proof. It's her tried and true formula she's been using for over a decade.
