24 alternatives to Race Timing with Integrated Replay
Instead of playing video and trying to display timing information next to it, how about we build a simulation based on timing data and become able to determine the state of the race at any given point in time based on the few 'radar blips' of sector loop passes we have? This is that. It takes the video and timing material of a 24h race (The IMSA Weathertech Sportscar Championship ROLEX24 at Daytona 2024) - 4 videos hosted on YouTube and a big CSV of laptimes and reimagines how a race replay might look like. It comes with a few non-standard visualizations, and a lot of possibilities for…
Race Timing with Integrated Replay reconstructs a 24-hour motorsports race by combining video footage and lap timing data into an interactive simulation. Rather than syncing video with timing overlays, it uses sector… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

undercutf1 is a F1 live timing app, built as a TUI. It contains traditional timing pages like a Driver Tracker, Timing Tower, Race Control, along with some more detailed analysis like lap and gap history, so that you can see strategies unfolding. I started to build undercutf1 almost two years ago, after becoming increasingly frustrated with the TV direction and lack of detailed information coming out of the live feed. Overtakes were often missed and strategies were often ill-explained or missed. I discovered that F1 live timing data is available over a simple SignalR stream, so I set out…

Hey everyone! I'm a huge F1 fan and got tired of juggling multiple tabs and apps during race weekends, so I built F1 COSMOS. What it does: - Live timing: Real-time data updates in milliseconds - sector times, telemetry, team radio, you name it. No more refreshing pages or waiting for delayed updates. - Replay feature: Missed qualifying or fell asleep during practice? You can replay the live timing from any past session. Pretty handy when you're in a bad timezone. - Proper data visualization: I went beyond just showing lap times. There's race analysis with telemetry data, championship…

Hi I'm Dan from Elodin, making an open source real-time capable flight software simulation. For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling. If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly. The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically…

Been having a lot of fun reading an SC2Replay collection through nom parsers, serializing into Arrow files so that pola.rs can read them and perform data analysis with jupyter lab, plotly or interact with SQL operations, etc. Looking for feedback and ideas on what to progress on. For example, "through history, are my timings getting better?". etc. Also would love to have ideas on what libraries to use to perform forecasting.

Hi HN, I'm one of the founders of s2.dev. RePlaya (https://github.com/s2-streamstore/replaya) is a self-hosted browser session replay tool using rrweb (https://github.com/rrweb-io/rrweb). It occurred to me that a durable stream per session would be a much neater architectural foundation for much of what you'd want from such a tool. As a unique feature, it also made live tailing straightforward because the player can read from the same stream the recorder is appending to. The alternative architecture is likely an ingest firehose which is then indexed,…

Hi HN, I recently noticed a recurring visual artifact in the "Most Replayed" heatmap on the YouTube player. The highest peaks were always surrounded by two dips. I got curious about why they were there, so I decided to reverse engineer the feature to find out. This post documents the deep dive. It starts with a system design recreation, reverse engineering the rendering code, and ends with the mathematics. This is also my first attempt at writing an interactive article. I would love to hear your thoughts on the investigation and the format.

Hello HN, we’re open sourcing a new library called Quix Streams (https://github.com/quixio/quix-streams)—a high-performance Python and C# library that processes time-series telemetry data with message broker such as Apache Kafka, instead of a database. We’re a team of engineers who all worked together at the Formula 1 McLaren pit wall. We struggled to get wanted we wanted out of existing stream processing tech, so we built our own platform called Quix. Although our original requirements were pretty niche (process over 60k data points per second), our solution is designed…
