OBS

Pros: Can do everything you want and more. The greatest piece of open source software I know. Nothing bad to say about it.

Cons: Nothing bad to say about it, really. The documentation and error handling could be improved, but given some time they probably will.

Overall: Great experience. Of course, there is a learning curve, but that is definitely worth it. No commercial software encoder is this good.

Pros: I mainly use this for live streaming on Twitch and YouTube. I love the fact that it is free to use and for me it is the best software to use for anyone who is looking to live stream or record. It is also great for those people who do podcasts.

Cons: I do not think it is the easiest software to adjust to and there is a slight learning curve but once I took the time to learn all the features and how to use them it became the perfect software for me. I also think it lacks features that allow for people to easily set up their live streams.

Overall: I love OBS and I would highly recommend it to anyone who is looking for live stream or recording software.

Pros: Has many features like adding input and output.
Free software with these features.
Available on multiple OS Windows, Mac and Linux.

Cons: Bad user interface.
Hard to use.
Very heavy on CPU and GPU.

Overall: I used it on Twitch a couple of times and my PC was running like crazy. I am not sure why using it consume a lot of CPU and GPU comparing to other softwares.
I wish they fix the user interface or adding a better overlay.

Pros: -They have a very clear tutorial on their website
-Once you have everything set up, it is very easy to use the exact same settings by saving profiles and scenes
-Automatically exports your videos to a folder you choose
-Very versatile in usage
-It's free

Cons: -Learning curve
-It's a very heavy software, so not every computer can handle running OBS and getting smooth results

Overall: OBS is a great tool for screen capture. There is a small learning curve and you will have to tinker with the settings a bit when starting out, but the option to re-use your previous settings makes for a quick second start.

Pros: Highly customizable - You can install plugins, and edit OBS as you like.
Open source.
Totally free - you don't need to pay a single penny.
Integration with streaming services (Twitch, YouTube, etc.)

Cons: No cons for me, at least. I haven't found any issues.

Overall: Overall, OBS Studio is a great choice for streaming and recording videos. I've used OBS in 2021 for a webcam on Google Meet in my classes, so I customized it to the limit. It's a great tool - and I would encourage anyone to learn and use OBS.

Pros: -the 'quasi-standard' tool for streamers
-lots of flexibility and capability build into the base software
-add-ons expand the capabilities even more
-totally free ! yet professional level reliability and capabilities (for the serious streamer)

Cons: -on the edge of too much capability
-menu structure and where all the options are takes some getting used to
-add-on management needs improvement

Overall: If one is or wants to become a streamer, one better gets familiar with OBS. If there is something you want to do while streaming online (like bringing a cellphone video conference call into a live stream), there is likely a way to do it. Through in that it is completely free, very capable and reliable - and you've got the arguably best video streaming tool.

Pros: Free and open source
Video recording
Great performance
Live streaming to multiple outlets
Game Capture with good frame rates
Highly configurable
Available across operating systems - Windows , mac and Linux

Cons: No Cons for OBS. It does everything it claims to be and is free. One suggestion would be to release a lite version for the less technical individuals.

Overall: OBS is an excellent video recording and screen capture tool but when it comes to livestreaming it is the best in the business. It provides great performance and provides lots of configurations to suit any needs. The best part is it is totally free.

Pros: OBS is really easy to setup and use. I find its layout/GUI very intuitive and easy to navigate.
It is very easy to add different sources for both video and audio and arrange them (there are multiple options for sources) . It is also very easy to convert/remix recorded files into a different format (although I personally use a different software for that).
You can easily customize and optimize the bitrate and output size. This is great if your internet signal isn't great (streaming mode), or if you want to record a HD video for a presentation (recording mode). You can adjust accordingly

Cons: One little thing that I find could be improved a little bit is the visibility of the "recording", "paused" status. As you pause a recording or resume a recording, you want it to be clearly visible. It happened to me a few times, that I hadn't click properly on the resume button or have clicked accidentally on the pause button without noticing it.

Overall: I've started to use OBS Studio to record my lecture during the Covid-19 pandemic and it didn't take long to master its capability. You can do a lot of things with it from very basic recording to very advanced scene creation.
Although, it something I haven't used much, but the process of installing and incorporating plugins could be improved in my opinion.
OBS Studio is a great program. It can be configured to your needs as a recording program and even create a professional-level final product for sites such as YouTube. Personally, I recommend this tool.
