I’ve helped a few people in the past. One of the topics used `import processing.video.*;`. I can not remember that I had to install that library specifically (possibly I did use of version of Processing IDE 3.x) but I might be mistaken. However today I had to manually install the library.

I do not know if this is due to an oversight when the Processing IDE is build or if the approach by the developers has changed. I found a topic going back to May 2022 ([Video library simply missing?](https://discourse.processing.org/t/video-library-simply-missing/36963)) so it seems to be an old issue.

If this was not due to an oversight I would like to suggest that a note is made in the library reference ([Video / Libraries / Processing.org](https://processing.org/reference/libraries/video/index.html)) that this library has to be installed manually.  
If it was due to an oversight I did expect it to be fixed by now 😉 But if nobody tells the developers … Where can I report this? [https://github.com/processing/processing4/issues](https://github.com/processing/processing4/issues)?

The same applies to the sound library (and there might be more).

Remark:  
What is strange (to me) is that some libraries (e.g. _Serial_ or _PDF Export_) do not require manual installation.

Forgot to mention ☹  
Windows 11  
Processing zip installs of 4.3, 4.4.7 and 4.4.10; all point to the same sketch directory (but I think that that is expected).

As far as I understand it, the video library was unbundled because it is huge (300mb).

It indeed took a while to download. But that does not apply to the sound library.

Suggestion still stands 😉

I feel this is going off topic…

They all share the same “Sketchbook Folder” directory.

You can customize your environment for each install:

I don’t mind too much if I can learn 😉

I know that 🙂

And that I did not know so thanks 👍 I have no need for it at this moment but it might be useful in the future.
