Video Capture Cards Are a Must

In recent years, live streams have become increasingly popular and video games have become the most popular type of content to stream. The instant interaction and constant presence of a streamer allow the audience to have a greater sense of participation, which can bring plenty of business opportunities in various industries. Popular streamers have even affected the sales performance of game developer companies.

With live video game streaming, it’s easier to record and share content on a PC compared to game consoles such as PS5, Xbox, Switch, and others. The invention of the video capture card solves this problem as long as it’s connected to a game console and PC. This product has rejuvenated the e-sports streaming market. However, video capture cards have several compatibility issues that can affect the live-streaming experience for both streamers and audiences.

What To Do When a Live Stream Starts Lagging

From our experience, Allion’s e-sports consulting team found that the most common problem encountered during live streaming is there is no audio or the audio is laggy. This has caused a lot of trouble for streamers and audiences.

The Reason For Lag

Our e-sports consulting team experimented with the PS5 games first. The first step was to analyze and summarize the most common scenarios that streamers will be in, then connect all the devices that will be used (shown in Figure 1). The most popular streaming software was downloaded and used for this experiment. To simulate different streaming hosts, 9 different devices with various hardware specifications were experimented with, covering all possible scenarios. Lastly, 3 different video capture cards were chosen and applied to these scenarios, simulating a real user scenario that can help us discover potential issues that streamers encounter during their experience.

The table below shows the results of the experiment, which is when the PS5 gaming console is paired with an M2 Mac or Dell PC, audio issues such as no sound, low volume, or audio breaking up can occur.

Our e-sports consulting team further analyzed these audio issues and found two possible reasons for them:

  • Reason 1: Compatibility issues with built-in applications
  • Reason 2: Compatibility issues with the operating system and the audio card driver

Relying on experience, our e-sports consulting team took this issue step by step and finally solved these problems with a software update.

Our team also learned that other than the streaming scenarios mentioned previously, video capture cards also have usage scenarios for digital cameras, transcription of video and audio recordings, online meeting recording and screen sharing, and more. We can see that serious audio issues can only be found by simulating real-world scenarios like our team did, and there is much more to be found in other e-sports applications.
