I asked Claude Code (Opus 5.5) to make a launch video for a fake calendar app and HOLY fuck, everything you see AND hear is code ONE prompt, it cooked for about 8h name, logo, UI, animations, soundtrack, sound effects opensource, repo in replies :)

Github repo: code, soundtrack and the video are all in there

This is by far the best launch video generated by opus 5.5 by a mile..

yes i agree hahaha

*8h runtime includes a lot of reviews/video recording(cloud agent/took 30min)

This you can tell it’s a ai video, but only if you know about ai. This isn’t as sloppy as the other ones because you gave it a direct direction. Will try out

The video itself is master-class if you ask me. But watching alot of these opus 5.5 launch videos i really have to say that i dont like the "music" it creates for the videos. But maybe its just me

yeah i feel the same. The animations are pretty insane but the soundeffects and bg soundtrack don’t really match this type of video

fake app, real launch video, priorities fully intact

What prompt did you use?

Im more curious how u prompt it? Can u share it?

Eight hours is an unattended shift, not a one-shot.

This is the only one that i have seen that has 85% intentionality on the frames

Holly cook

8 Hours? What are u talking about.. u can do much better in less than an hour..

Show me!

Both one shotted, just a prompt and repo.. both under an hour..

@LexnLin Nice but not better imo

@LexnLin Not better, yes But 8x quicker and fully editable..

@nickneely00 yes but you said you could do much better in an hour?

this is crazyy

much better but it seems like every one of these follows the exact same pattern the shake animation and the one that follows beat

the flex is the 8h, but the number i'd want next is attempt #2's cost: replayable from checkpoints in minutes, or another 8 hours from scratch? that one decides demo vs pipeline, and it belongs in the README next to the video.

This one's of a real open source memory layer release

did you use a gauntlet loop?

my After Effects past:

yea we do not need motion designer now

Yeah, for people not wanting to spend a lot of money, you can pretty good videos now

Looks awesome 👌. But 8 hours? How did you manage usage limits?

보이는 것도 들리는 것도 전부 코드라니 진짜 놀랍네요, 프롬프트 하나로 8시간을 굴러갔다는 게 제일 신기합니다.

What prompt did you use? Do you also have it somewhere in the repo?

One prompt, 8 hours. What did the token bill look like?

8 hours for this is a bit much Maybe more than a bit 🤔

An app that doesn't exist shipped with a soundtrack. Funnier launch than most real ones.

at this point i don’t even know if people are joking or not

check the repo lol

8 hours on one prompt is the wild part. Did it ever get stuck and need you, or did it run clean start to finish?

Did it use skills for this? Looks very good. I’m starting to feel Claude may also be developing a bit of a sense of humor and irony?

Eight hours for one prompt is a heavy investment. It’s less magic and more rendering: the model generates code that then builds assets in real-time

wtf

Where is the prompt?

8 hours for that? That's impressive. Can't wait to see the repo!
