![]() Recording Path: Browse to define where the recording will be stored.This is only important if you plan to record your stream either for later Video On Demand work or as a reference. X246 options: You can really start to fine tune the stream with custom coding but this would take a much longer guide and probably me not writing it.Tune: "None" works most of the time, but you may need to fine tune.Profile: I’d opt for "High" or "Main" as it forces a better encode, but switch to "None" if you notice frames dropping.CPU Usage Preset: This is the preset for the OBS x264 Encoder - I leave mine set at "Fast" which seems to work fine.If this was set to 10 they would have to wait 10 seconds, whilst at 2, you only wait 2 seconds. So if a viewer watching your stream moves out of wifi range and jumps onto another network with a slower download speed, they could only join again at the next KeyFrame. Remember, a viewer can’t start watching from a delta frame, only a KeyFrame, as that is the frame that has all the information. For broadcasting, the KeyFrame interval used to be set at 10, but for live streaming 2 is much better. A KeyFrame is a fully rendered frame image in a video, whereas subsequent frames/delta frames actually contain the information that has changed. KeyFrame is another vital setting that often gets forgotten. KeyFrame Interval: I set this to 2 rather than “auto”.Custom Buffer Size: I leave this unticked.That means having a steady 10Mbps broadband connection per stream. For a 1080p HD frame running at 25 or 30fps I would set my bitrate to 6000kps. So, plan to use only 70% of your true bandwidth. You need to leave some space for network fluctuation and some headroom for audio. If you have an upload speed of 10Mbps, then theoretically the maximum speed you could stream at is 10,000 kbps however, this does not work in practise. Bit rate refers to the quality of your stream being uploaded or transmitted. Bitrate (this is key!): Here you need to balance how fast your internet connection truly is against the quality of your stream.I always select CBR (Constant Bit Rate) as it is the most straightforward for streaming. Rate Control: The options here are for which type of BitRate you want to you use.Personally, I would do this in the Video settings further on. Rescale Output: You can choose to rescale your frame size, if, for example, you have set up to work in 1080p but only have internet speed to stream at 720p.Enforce streaming service encoder options: This has no impact on a TicketCo stream.Experiment to see what gives you the best outcome for your setup. If working on a Windows machine with an Nvidia graphics card, try NVENC. This is better than the other options unless you have a very fast graphics card. This means that in sources I also need to assign any audio inputs to track 1. You can only choose one, and for simplicity I make this Audio Track 1. Audio Track: Here you can define which audio track will be broadcast.Streaming tab: These are the settings for the live stream.First, change Output mode from Simple to Advanced in order to reveal the settings you need. Heres you can define what you will be outputting over your stream and recordings, and this is vital. Here you can set up what your multi view might look like. One thing to note is that right at the bottom of the screen are the settings for Multi view - this is useful if you are using OBS as your A/B switcher. Most of the settings here are self explanatory. There are many alternatives to OBS, and if you are using an alternative, note that these setting can equally be applied there. This RMTP pipe or link is how you send your live stream to TicketCo’s servers. OBS essential encodes incoming captured video and audio data and transmits that data via Real Time Messaging Protocol (RMTP). OBS is an open source cross platform software for live streaming and recording, and it is largely referred to as OBS Studio. ![]() TicketCo has a more introductory OBS guide found here if you need help getting started.Īlways bear in mind that TicketCo will broadcast your video at a maximum frame size of 1080p and at a frame rate is 30fps. ![]() This guide will help you optimise your settings and preferences, rather than teach you how to use OBS. There are a myriad of OBS tutorials online and I recommend EposVox’s masterclass (just give him a search on YouTube). They are a mix of trial and error, a lot of YouTube videos and forum searching. The notes that follow are based on my experience of setting up OBS for TicketCo’s servers. By Simon Baker, Technical Director and Digital Producer at Wise Children
