Used @cap as an MCP for the first time - very busy lately with work and it did a great job with recording a product demo for me while I work on other things! This is the future.

Instant recordings in Cap now process up to 17x faster. Under 1 min: 10s → 3.5s 1-5 min: 32s → 5s 5-15 min: 72s → 7s 15+ min: 5 min → 18s We now run our own GPU farm, and Cap does most of the work while you're still recording 🫡

I binned off Loom, man it's gone downhill - typical Atlassian "improvement". Switched to @cap and it's been amazing, it just works - which is what we want!

Working on the next launch video for Cap 0.6.2 This release is going to be a banger. A few heavily requested features and even more performance improvements. I wonder if we can keep knocking out back to back releases like this now, every single week?

Since posting this, we’ve merged 452 PRs. We’ve now sponsored 18 people through GitHub, with $1,275 paid out in total 🫡 The offer still stands... make Cap’s GPUI desktop app faster, show it with benchmarks, and we’ll sponsor you!

Proposition: you create a PR in Cap’s repo with a performance improvement. Can be for the recording engine, export engine, playback, whatever. It should be a demonstrable performance increase with benchmarks. Specifically for the GPUI app. In return, we’ll sponsor your GitHub 🫡

To clarify, Cap uses 440 MB of memory when actively playing back a video in the editor (1440p, M4 Max). When idle with just the main window open, it uses 68 MB of memory and 0.00% CPU 🫡

440 MB still seems like a lot for a UI, what's eating the memory now that the web view is gone

Another PR merged into @cap , this is the third merge🥳 On Windows and Linux, Cap’s recording picker shrinks a screenshot of every screen into a thumbnail. On a 4K screen that took 124ms. Now it takes 29ms. Up to 4.3x faster, and the output is identical down to the byte. github.com/CapSoftware/Cap/p…

@Cap is really amazing. It's open-source, which is cool. It also just WORKS, which is especially nice on Linux where so many of the alternatives I tried are trash. cap.so

11 PRs merged into @cap so far, so obviously I (cough my friend opus 5.5 cough) made a video about it instead of touching grass The cursor recorder was hashing the exact same cursor image every single tick, even when nothing changed. Basically checking your pocket for your keys over and over while they're in your hand. With a big cursor that was 5,204µs a tick, now it's 538µs Finding your mic for the recording hotkey took 280ms. Now it's 0.32ms The mic meter was waking up the main thread 93.8 times a second. Now it's 7.2, and 0 when you're silent - which is more than anyone can say about me Timeline repaints with 120 clips went from 2,178µs to 96µs And one of them just fixes the lint that turned main's CI red. Massive cheers to @richiemcilroy for reviewing and merging all of these 🫡 (I forgot to specify that I wanted a 16:9 video not 9:16 - I need to save the extra tokens for more PRs)
