From Repo Docs to Promo Video

April 6, 2026

Tl;DR

Last year here… I was working for some kind of project to do automatic docs

Intro

But models have improved a lot

#Copy your public key:
cat ~/.ssh/id_ed25519.pub
#Copy the full output.
#Add the key in GitLab:
#Go to GitLab -> Preferences / Edit profile -> SSH Keys -> paste the key -> Add key.
#ssh -T git@gitlab.com
git clone git@gitlab.com:fossengineer1/fossengineerpapermod.git

This started long ago

Extracting Repo Info

Previously I was using interesting workflows with scripts.

Like I have at folders like Z_codex_posts or Z_OpenAI_POSTS.

But…

agents are beyond that at this point

From Repo to Post

Lets go with an example?

git clone https://github.com/elduty/velomate
claude

Ive already built an skill for this: foss-post

Because thats really all there is: https://skills.sh/

Skills are reusable capabilities for AI agents. Install them with a single command to enhance your agents with access to procedural knowledge.

#npx skills add https://github.com/github/awesome-copilot --skill documentation-writer
/foss-post /home/jalcocert/Desktop/TBT/velomate --depth medium

Meme - Fantastic

You can also see other that people created

From Repo to Video

How about…creating/combining another skills, so that we do video?

Yea, remotion again:

About FOSS - Repo to Video

What if for every cool repo not only a nice post could be generated:

#git clone https://github.com/davidmonterocrespo24/velxio ./Desktop/TBT
claude #/skills #use the foss-post against the cloned repo
cp /home/jalcocert/Desktop/TBT/velxio-post.md
      /home/jalcocert/Desktop/fossengineerpapermod/content/posts

Velxio | Docker Config 🐋 ↗

But also a nice RemotionJS video about it?

If you do the: make sure to do it on a folder w/o git, or it wont prompt you for the add skills part and avoid creating a totally blank folder!

npx create-video@latest #y / blank
cd ./my-remotion-video
npm install
npm run dev #now it works!

mv /home/jalcocert/Desktop/video-test-remotion /home/jalcocert/Desktop/fossengineerpapermod/z-remotion-oss/video-test-remotion
  
#/home/jalcocert/Desktop/VideoEditingRemotion/remotion-cc/.claude/skills/remotion-best-practices

cd ./z-remotion-oss/video-test-remotion
npm run dev

 ok so inside that video-test-remotion, can we make a video that describes
  what velxio does, using the UI/X of its components or any png that they
  have at the repository? the video should be appealing for selfhosting
  enthusiast

npx remotion render VelxioShowcase selfhosting-velxio.mp4

Conclusions

This is the kind of post that makes me realize this year ill be doing 99 posts…instead of the much less planned.

Talking about f/oss I tested mac OS with Zed and CodeEdit

Interestingly, there is a fork of zed called GRAM that has been quite interesting.

Lack of disk space?

What ive tried recently

What else am I running since last month?

#git clone https://github.com/JAlcocerT/Home-Lab/
#cd ./Home-Lab/z-homelab-setup/evolution 

#docker ps --filter "status=running"

Termix with Docker 🐋 ↗

Which reminds me somehow to tmux the one I used here with blender and my x300

#brew install ffmpeg #you didnt know you need FFMPEG, but you DO NEED IT
brew install gh
#gh auth login
#gh auth status
git clone https://github.com/JAlcocerT/3Design
cd ./3Design/mbsd-to-render/four-bar

make check #make help
#make scene-ui #this starts blender UI
time make all #makes all the steps, including the render programatically!
#make render #or do this one for just the render of the scene-ui was OK

#tmux new-session -d -s cad "make all" #if you will be leaving this for the night
#tmux attach-session -t cad #to see hows going

Wait….56 seconds to render?

On battery power?!

My 5600G was taking like…10 min?!

that was for 1080p, so i went ahead and made it harder:

cd four-bar-mac
make clean-all
make install UV_PYTHON=3.12
.venv/bin.python --version

#make scene-ui
time make render all

Say thx to pairdrop, see the difference

Oh the time for 4K with final presets?

This was 26min at the M2 and I did not dare to try it with my x13 nor the x300.
