OBS Studio

OBS Studio is an advanced Screencasting tool that is widely used by YouTubing Gamers as it allows the user to combine and brand a number of inputs as desired. If you're struggling with screencast basics then it might be too much but if you've got screencasting nailed and you're looking for something a bit more advanced this might be the tool for you.

The video below is one of my latest videos using OBS and includes an opening scene, a headshot scene, an embedded screencast and an ending. There is also a transition for thinking tasks along the way.

Resources below are a collection of the videos I used to get me to this stage. it took lot's of practice and experimentation but now I feel I can produce good quality interesting videos with no more effort than a regular screencast tool.

Random Tips

  • OBS Studio offers a great way of setting up a Visualiser which could be used to present live handwritten images/notes from your desk. You can play around with the zoom of the external webcam and also fix the focus to avoid your hand changing it when writing.

  • Better Sound - A common improvement recommended for Audio quality is to highlight your audio source in the scene > right click > filters > + > then add the Compressor and Noise Supression filters. Stick with the default settings and it will most likely be better than without the filters.

    • An extract from a blog post...

    • - to remove low volume noise while you are not speaking, use the noise gate on your mic source

    • - to duck an audio source while you speak (lower the volume of game audio while you speak), use the "Sidechain/Ducking source" option of the Compressor filter applied on the game audio source and set the mic source in the "Sidechain/Ducking source" option.

    • - if you're unable to speak with a constant voice, use the compressor filter on your mic source to amplify the parts with a low voice

    • - to make the signal use the complete volume range, use the expander filter on your mic source

    • - to avoid clipping of loud parts, use the limiter filter on your mic source

    • - the usual sequence is noise filter (only required with noisy microphones) -> noise gate -> compressor -> expander -> limiter
