What is the Best S-Video to HDMI Upscaler?


S-Video provides a significant jump in analog video quality over composite connections. It keeps luma and chroma signals separate for reduced noise and crisper visuals. However, modern HDTVs primarily use digital HDMI inputs.

To get the best picture out of retro systems, an S-Video to HDMI upscaler is needed. But with many budget converters to high-end scalers available, which option is right for you?

Key Takeaways:

  • Look for upscalers that support 480p, 720p and 1080p output resolutions.
  • Upscalers using advanced processing chips like Faroudja DCDi will achieve better video quality.
  • Additional features like scanline generators, color controls, and zero latency modes are worth the extra cost for enthusiasts.
  • All-in-one upscalers that also add HDMI from composite, component, and even RGB inputs provide flexibility.
  • Try to find comparison reviews matching your use case – gaming vs video – and types of source devices.

Why Upscale S-Video to HDMI?

S-Video separates color and brightness signals over two wires rather than combining it into one video line like composite. This enables clearer color definition and reduces interference.

On a CRT TV, S-Video can look nearly as sharp as RGB while using the same connector as composite. But on modern fixed pixel displays like LCD, plasma, and OLED panels, the low 240p/480i resolution of S-Video starts to show.

By upscaling to 720p, 1080p, or higher, retro game consoles and VCRs can gain:

  • Increased detail and clarity
  • Reduced dot crawl and noise
  • Lag reduction compared to composite
  • Ability to capture gameplay in HD via HDMI

Upscalers let you get the most out of classic S-Video sources on modern displays.

Testing Criteria for Best Upscalers

With a wide range of upscalers available, it helps to have criteria to judge which are the best options:

  • Video Processing – Chips like Faroudja determine scaling quality.
  • Output Resolutions – 1080p preferred. 480p min for most S-Video sources.
  • Input Latency – Lag between source and display.
  • Response Time – Video delay through the upscaler.
  • Configurability – Control over resolution, aspect ratio, etc.
  • Price – Budget scalers can be under $50 while high-end exceed $300.
  • Features – Scanlines, color controls, noise reduction, etc.

Testing and reviews focus on video quality, lag, and features for the price. Match the upscaler to your needs – gaming vs video playback – and choose the best fit for your budget.

Frequently Asked Questions

What resolution does S-Video support?

Standard S-Video typically supports 240p or 480i resolutions. Some later game consoles like Dreamcast can do 480p over S-Video.

Do I need an upscaler for 480p sources?

Most HDTVs support 480p over component for DVD players. But an upscaler is still recommended to deinterlace and scale 480p to 720p or 1080p.

What inputs do I need on my TV?

For an external upscaler, you need at least one HDMI input on your TV. Some scalers also provide pass-through composite/S-Video connections needing those legacy inputs too.

Why does my upscaled image look soft or blurry?

This is likely due to poor deinterlacing of 480i video or using a low quality scaling algorithm. Higher end upscalers will provide sharper pixel rendering.

Why is my upscaled image distorted or squished?

Incorrect aspect ratio or overscan settings on the upscaler could result in geometric distortion. Adjust the HDMI output settings to match your display.
