Kdenlive 24.02 open source video editor released
I've used Kdenlive, Shotcut, Blender and Olive [1]. They all have strenghts and weaknesses, so I choose which one to use depending on what I'm trying to do, or sometimes I use two of them through a single video project.
One thing to note is that Kdenlive and Shotcut both use the MLT video editing framework [2] under the hood, so their capabilities and constraints are very close to each other's. That said, their UIs are their own and some things may be easier to do in one over the other, may be a matter of personal preference. AFAIK Shotcut is developed by the same people who built MLT, but I don't think that gives it any particular advantage. Also both of these apps have the largest ready-made effects toolbox out of the four apps I mentioned at the top.
Blender's VSE (video sequence editor) is great if you need fine-tuned 2D animations of elements because you can use all the same awesome keyframing tools you'd use for 3D animation, but it's severely lacking in other aspects, especially in the effects dept (you can crop, blur, mask, but not much else). For some reason you can't use Blender's compositor node system with video, which would enable many more capabilities if possible. There's also a steeper learning curve if you've never used Blender before because its UI breaks many conventions.
Olive is a newcomer that doesn't get enough attention, but IMHO it was at one point the most promising OSS video editor out there. Sadly the developer works on it on his free time, and he's recently said that he's pausing development because he doesn't have the resources to work on it any more. I'm really hoping a miracle happens.
There's two versions of Olive, 0.1 and 0.2 which is a complete rewrite. Both versions are good, but they work pretty differently. What got me excited about 0.2 is that its effects are node-based (unlike MLT-based editors which are stack-based), which enables far more advanced editing, although you probably wouldn't need that unless you're working on something quite ambitious.

Solution to correct digital copy of VHS recording with horizontal "jitter"?
kdenlive / shotcut / olive editor are free & open source and maybe it works: https://youtu.be/ZPGwhDY03gw no idea what it'll do to your video. Most of these if not all use the https://www.mltframework.org/ which can be done on the command line so possibly if you have thousands of videos you can figure out an exported script that does it on them.
- what does this error mean and what can i do to fix it?
- I'd like to install the Linux MELT command line tool to be able to use on my Android phone. Would anyone be willing to help? I will compensate for your time

Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months
GPL2
Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?
IANAL, apologies if I miss understand license requirements.

Writing x86 SIMD using x86inc.asm (2017)
This turns out to be a lot of assembly macros to help write one x86 assembly. https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/x86/x...
The sibling comment recommending compiler intrinsics is probably the best way to go for writing SIMD code. A mixture of `` style types and intrinsics to specify instructions is a solid 90% solution compared to assembly.
If you want that last 10%, I think macros are putting the emphasis in the wrong place. They're a somewhat easy way to build up a language abstraction which will work if held carefully, but I'm confident the dev experience using this abstraction when you write invalid code will be deeply confusing.
I would suggest to write a parser instead of the macros. That'll tell you clearly when the syntax is invalid (though possibly not with much precision) and it'll give you a place to put semantic analysis for where valid syntax encodes nonsense. Do the equivalent of the macro expansions on the parsed tree instead of on the text. Emit asm as the "back end".

Video Generation with Python
You might have heard of FFMPEG or ImageMagick for image and video edition in a programmatic way. MoviePy is a Python module for video editing (Python wrapper for FFMPEG and ImageMagick). It provides functions for cutting, concatenations, title insertions, video compositing, video processing, and the creation of custom effects. It can read and write common video and audio formats and be run on any platform with Python 2.7 or 3+.

11 Ways to Optimize Your Website
There are many cloud-based tools and websites that can convert your images, but the problem with these tools is that you usually have to upload the files for them to be processed, and some of their services are not free. In this article, I'd like to introduce a piece of software called FFmpeg, which allows you convert the images locally with one simple command.
