![]() ![]() If you do plan on recording a local copy of your content, especially if it's in HD 1080p, you may want to save your hardware encoding option for that (see Step 10, below) and not use it for the smaller Facebook 720p encoding. ![]() So if you use hardware for Facebook Live 720p encoding, you might not also be able to also use it for recording to disk, for example. Not all hardware encoding options allow more than one thing to use them at the same time. If you have CPU cores to spare and your minimal bandwidth is important to you, then software encoding may be the way to go however, for most streaming scenarios, hardware encoding is more than sufficient. If you are streaming dynamic, fast-moving content with multiple effects or scene changes then you might want to compare the hardware encoded quality against the software encoded quality for best results. The main tradeoff is that the bitrate will be higher and the quality might not be as good - although it’s rarely a noticeable difference. Using hardware encoding, when available, is generally a good idea as it will free up your CPU for other tasks. This is called "hardware encoding" or "GPU-Accelerated encoding." NVENC is made by NVIDIA and will be available if you have a NVIDIA graphics card installed in your computer. "Quicksync" is made by Intel and comes with many of its CPUs that have an integrated graphics card (on Macs it’s called "Apple H.264"). You won’t see these options unless you have these chips in your computer. "Apple H.264," "Quicksync" or "NVENC" use chips on your graphics card, also known as your GPU (Graphics Processing Unit) to encode and compress the video. This is sometimes called "software encoding." This generally allows the computer to make “smarter” decisions when choosing what information to include and what information to get rid of when encoding your video stream and allows it to maintain the best quality:size (bitrate) ratio. "x264" uses the computer’s Central Processing Unit (CPU) to do all the encoding. In the screenshot here, you can see that I chose between "x264" and "Apple H.264." On Windows, you might see "Quicksync" or "NVENC" in addition to "x264." Depending on the hardware in your computer you will see between 2 and 6 different encoding options based on these settings. They only allow (or recommend) 720 HD video in either 30 frames or 60 frames per second.īy default, Wirecast will limit you to Facebook’s preferred settings. ![]() On another note, if you don’t know what "encoding" means in relation to video and audio or live streaming, you probably will want to read this article.Īlthough you don’t necessarily need to change anything, we'll discuss it now, so you have an idea of what the settings do and how they work.įacebook is quite strict on the size and quality settings of any live video you stream to the site via the Live API. We cover Frequently Asked Questions, including what computer to use with Wirecast. It’s also available immediately.If you don’t know what "quad core" means in relation to computers or why that matters with Wirecast, you should probably watch this video. It’s a neat system that, like all the best integrations, adds something in each direction. This method allows people to take the load off the Wirecast machine and lean on the BoxCaster's own hardware for encoding video and audio, as well as taking advantage of what the company refers to as ‘specially-designed communication protocols’ to optimize available network connectivity. The Wirecast program output can also be sent to a secondary HDMI or SDI output that is plugged into either a BoxCaster or 4K60 BoxCaster Pro. This is turn can be done with either a Single-Use RTMP or Static RTMP Channel, though in each case the setup must be done within 10 minutes of a scheduled broadcast. This allows it to stream directly to BoxCast, utilising the computer for encoding the video and audio, before TX using RTMP. Using BoxCast's RTMP video ingestion option, Wirecast users can select BoxCast as a streaming destination from within the software. These include single source simulcasting, video embedding, cloud transcoding and a fair bit more, and it all happens with admirable alacrity and a couple of different options. Telestream’s live streaming production software has been steadily picking up momentum in the field, and this new integration with BoxCast’s cloud-based platform opens up a range of new features to users. When it comes to live streaming in particular, things that happen with a single mouse click are deservedly popular. Telestream’s Wirecast live video production software has been integrated into the BoxCast platform to form a really quick, powerful end to end streaming system. If you are streaming the normal way to your profile or page, Wirecast makes it easy: Click Output, then 'Start/Stop Broadcasting' then click your Facebook Live stream that you created earlier. The 4K60 BoxCast Pro can take the train of video and audio encoding in the new system 3 Start Streaming Its now time to go live. ![]()
