Why HC Encoder Remains a Hidden Gem for MPEG-2 Video

HC Encoder (HCenc) is one of the most powerful, highly regarded freeware MPEG-2 video encoders, widely used for creating ultra-high-quality DVD and Blu-ray compliant video streams. Because it relies on AviSynth scripts (.avs) or DGIndex (.d2v) files for input, properly configuring its internal settings is crucial to maximizing picture quality and encoding speed. 🚀 1. Core Prerequisites & Input Setup

Before opening HC Encoder, you must supply it with a properly formatted video script.

Use AviSynth: HCenc does not accept raw MP4 or MKV files directly. You must create a basic AviSynth script (.avs) to feed the video decoder frame-by-frame.

Resolution Restrictions: For standard DVD compliance, ensure your script scales the video to exactly 720×480 (NTSC) or 720×576 (PAL). The dimensions must always be divisible by 8. 🎛️ 2. Main Tab: Optimal Settings
