Smartcut: Super fast cutting and trimming of videos

What My Project Does

Smartcut is to my knowledge the most robust open-source implementation of frame accurate video cutting without recoding, a.k.a smart cut, smart encoding, smart render, etc.

It uses PyAV and libavcodec (ffmpeg internals) to encode a small part of the video near the cutpoints and then uses libavformat to stitch the recoded segments and parts of the original video back together into a whole video.

https://github.com/skeskinen/smartcut

Target Audience

This project is for people who want to cut videos really fast from the command line. This could be useful e.g. as part of a script that goes through a directory and quickly cuts off some part of the videos. It could also be used as a part of a video editor project, like I've done in my GUI video editor project.

It is also one of the largest available projects that uses PyAV (the pythonic bindings for libav project) and really showcases the awesomeness of the library. I also contributed 4 patches to PyAV and the maintainer was really cool to work with.

Comparison

The github page has a pretty nice list of related projects: https://github.com/skeskinen/smartcut?tab=readme-ov-file#other-projects

The most obvious comparison is to lossless-cut which is a popular open-source video editor written in TypeScript and Electron

Is Django Still Relevant for Backend Jobs?

Hi Djangonauts!

I'm a junior CS student with some experience in Django (intermediate functionality, needs frontend work). While I enjoy using Django, I'm concerned about landing a job with it after graduation. Many postings seem to focus on C# and .NET

My questions are:

Is Django still a valuable skill to learn for backend development positions?
Would focusing on C# and .NET offer better job prospects, considering the current market?

My dilemma:

I'm unsure if I should continue building my Django skills or switch gears to C# and .NET for better job security.

I'm feeling some pressure to upskill and avoid the pitfalls of job seekers lacking the right skills.
so I'm trying hard and pushing through burnouts, trying to upskill in order to strengthen my capability and candidacy.

Why not just get your plots in numpy?!

Seriously, that's the question!

Why not just have simple
plot1(values,size,title, scatter=True, pt_color, ...)->np.ndarray
function API that gives you your plot (parts like figure and grid, axis, labels, etc) as numpy arrays for you to overlay, mask, render, stretch, transform, etc how you need with your usual basic array/tensor operations at whatever location of the frame/canvas/memory you need?

Sample implementation: https://github.com/bedbad/justpyplot

# What my project does?

Just implements the function above

When I render it, it already beats matplotlib and not by a small margin and it's not the ideal yet:

Plotting itself done in vectorized approach and can be done right utilising the GPUs fully

plot1, plot2 .. plotN is just dependency dimensionality you're plotting (1D values, 2D, add more can add more if wanted)

Target Audience? What it Compares against?
Whoever needs real-time or composable or standalone plotting library or generally use and don't like performance of matplotlib [1, 2, 3\]

I use something similar thing based on that for all of my work plotting needs and proved to be useful in robotics where you have a physical feedback loop based on the dependency you're plotting when you manipulating it by hand such as steering the drone;

Anyone made the switch from ASP.NET Core?

I'm a .NET developer by daytrade, and I'm starting side projects from time to time. Usually it's been Node.js/Go/ASP.NET, but I've never done Django yet. I'm just not a big Python user in general.

However, it now looks like I have to build an admin panel by myself for a side project I've just started, and Django entered my mind as it's got one by default. It looks like Django + DRF is sort of a ASP.NET/Spring lite-edition, so I'm looking to see some feedback if anyone has actually moved from ASP.NET to Django, or just used both and have some feedback to share.

One thing I'm kind of suspicious about is the performance. ASP.NET is what, 10x faster than Django? However I know it probably won't make a real difference, but seems a shame if there is no real benefit to using Django.

Web scraping with GPT-4o: powerful but expensive

Hey folks,

So I've been messing around with OpenAI's new structured outputs feature and decided to build an AI-powered web scraper. Thought I'd share some of the cool (and not so cool) stuff I found.

**The Good:**

* This thing can parse some pretty complex tables. I threw a 10-day weather forecast at it with all sorts of nested data, and it handled it like well.
* It's smart enough to figure out merged cells and hidden data in the HTML.

**The Bad:**

* Wikipedia tables with combined rows? Yeah, that broke it.
* Asking it to give XPaths directly was a mess. Had to do some workarounds.

**The Ugly:**

* GPT-4o is expensive! Spent $24 in two days just messing around.

I made a quick demo with Streamlit if anyone wants to check it out: [https://orange-resonance-9766.ploomberapp.io](https://orange-resonance-9766.ploomberapp.io)

Deploying on Choreo.dev?

Hi Guys,

I am testing out different options for hosting my django + postgresql + react application. I found https://choreo.dev/ very convenient because i can manage all parts of the application on one dashboard instead of using 3 different providers.

However, it makes me a little suspicious that you can hardly find anything about choreo on the internet + the documentation is also not that extensive.

Do any of you have experience with the provider, and if so, what do you think?

Please help us test new Flask deployment tooling

Hi,

I work for Canonical, the creators of Ubuntu. We have been working on some new tooling to make it easier to deploy Flask applications in production using Kubernetes. This includes tooling to create Docker images as well as tooling to make it easy to connect to a database, configure ingress and integrate with observability. We would love your help and feedback for further development. We have a couple of tutorials:

[Creating a production ready Docker image](https://documentation.ubuntu.com/rockcraft/en/latest/tutorial/flask/)

Please share any feedback you have. We are also running user experience research which takes about an hour to complete. Please let us know if you are interested (DM me or comment below). Thank you!

Generators underused in corporate settings?

I've worked at a couple of places that used Python. And I've rarely seen anyone regularly using the yield keyword. I also very rarely see people using lazy "comprehensions" like

foo = (parse(line) for line in file)
bar = sum(postprocess(item) for item in foo)


And so, I'll use these features, because to me, they simplify things a lot. But generally people shy away from them. And, in some cases, this is going to be because they were burned by prior experiences. Or in other cases it's because people just don't know about these language features.


Has this been your experience? What was the school of thought that was in place on your prior teams?

Is there any plugin or Django app like this?

Supposing you have multiple users on your website and they receive points for doing something (posting, writing reviews, anything you choose to) and there are a few groups of users, each group having different rights and privileges on your website and the users are upgraded or downgraded to different groups based on accumulated points.

How to do this in Django? Is there any plugin or app helping you with this? If you just need to use pure Django then how this should be done?

Thank you in advance!

Using HTMX with Django is much easier than I thought!

I have recently given HTMX a try halfway through working on a Django project that needed dynamic content loading. It took me so long to give it a try because I thought that it would be hard to learn, but I was sooooo wrong. 😅

So it turns out that to add dynamic content loading all I had to do is:

1. Make a partial template of what I wanted to dynamically load.
2. Add HTMX to project
3. Add HTMX attributes to HTML

For this project, where I dynamically loaded available properties based on selected dates and number of guests I used these 3 HTMX attributes on my form element:

1. hx-get : to make an asynchronous HTTP GET request when an event is triggered
2. hx- target : to select the target element where we want to load the dynamic content.
3. Hx-swap: defines how the content retrieved via an HTMX request should be inserted into the target element on the page.

I found two things a little difficult to figure out:

1. Choosing the correct swap attribute: at first I tried outerHTML, but after some trial and error, I realized that innerHTML was the right choice.

1. Detecting HTMX requests in my Django view: It took me some
