AV CVBS to 3G-SDI Audio Video Converter Composite to SDI Converter

In this review of the AV CVBS to 3G-SDI Audio Video Converter, the bottom line is simple: this compact utility is for users who need reliable conversion of a single composite (AV) source into broadcast-friendly SDI outputs. It is particularly useful when feeding older CRT players, VHS decks or training-room sources into an SDI infrastructure. The main reason to buy is straightforward - it converts analog composite and stereo audio into HD or 3G-SDI with supported 1080P resolutions and dual SDI outputs, making legacy equipment compatible with modern recording or monitoring chains.

Key Features

• Composite to SDI conversion: Converts a single AV (composite) input and stereo audio into HD/3G-SDI signals so older sources can be used with SDI systems.
• Dual SDI outputs: Provides two SDI output ports so the converted feed can be sent to two monitors or recorders simultaneously without extra splitters.
• Multiple HD resolutions: Supports a range of SDI output resolutions including 720P and 1080P/I modes to match common broadcast and recording formats.
• Distance-capable outputs: HD SDI output distances up to 200M and 3G-SDI up to 100M allow longer cable runs in a control room or studio environment.
• Stereo audio passthrough: Carries stereo audio along with video on the SDI stream so the audio from legacy players stays synchronized with the converted video.

Who It's For

This converter is aimed at broadcast engineers, small production studios, security system integrators, and training facilities that need to bring composite sources into an SDI workflow without replacing legacy hardware. It is a practical choice for anyone who needs a simple, single-channel conversion with reliable SDI outputs.

Those who should look elsewhere include users needing support for SD-SDI signals, multi-channel AV inputs, or an all-in-one scaler with advanced frame rate conversion features. It is not a substitute for a multi-input video processor or a professional standards converter with extensive control options.

Pros & Cons

Pros

• Straightforward conversion from composite to HD/3G-SDI for easy integration of legacy sources.
• Two SDI outputs let you feed a monitor and a recorder simultaneously without extra hardware.
• Supports common HD and 1080 interlaced and progressive resolutions for compatibility with many devices.

Cons

• Does not support SD-SDI signals, so very old SD-SDI workflows are not accommodated.
• Only a single AV input is supported, limiting use where multiple composite sources must be converted at once.

Specifications

Our Verdict

This converter is a pragmatic, cost-effective tool for anyone who must bring composite video and stereo audio into an SDI environment. It is best for single-source applications in broadcast rooms, CCTV systems, or training showrooms where dual SDI outputs and common HD resolutions are required. For those needs it offers clear value, but users requiring SD-SDI support or multi-input conversion should consider alternatives.

Frequently Asked Questions

Can it convert both video and audio?
Yes. The unit converts composite video and passes stereo audio through on the SDI outputs.

How many SDI outputs are available?
There are two SDI output ports so you can feed two devices simultaneously.

Does it support SD-SDI formats?
No. The converter does not support SD-SDI and handles HD-SDI and 3G-SDI only.
