What is WTV?

Windows Recorded TV (WTV) is a container format for recorded television broadcasts from Windows Media Center.

What is HEVC?

Raw H.265/HEVC is an elementary stream of High Efficiency Video Coding data, doubling compression efficiency over H.264.

When Should You Use WTV vs HEVC?

WTV vs HEVC: Key Differences

• •The core technical difference: WTV relies on lossy compression whereas HEVC uses lossy compression.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Alpha channel support: HEVC lacks transparency support.
• •WTV files are typically Large, 2-4GB per hour of HD video while HEVC files range 50% smaller than H.264 at same quality
• •Use case fit: WTV targets windows media center recordings, tv capture and HEVC targets high-efficiency video encoding, 4k/8k streams — your choice depends on which workflow stage you are serving.

Advantages of WTV

• ✓WTV applies lossy compression specifically calibrated for Windows Media Center recordings, TV capture.
• ✓WTV enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓WTV delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find WTV support built into virtually every tool that handles Windows Media Center recordings, TV capture — no plugins or converters needed.

Advantages of HEVC

• ✓HEVC compresses data using lossy methods, keeping file sizes manageable for High-efficiency video encoding, 4K/8K streams.
• ✓Industry-wide support means HEVC files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make HEVC ideal for email, web uploads, and cloud storage.
• ✓From professional software to open-source alternatives, HEVC works out of the box.

Troubleshooting WTV to HEVC Conversion

• !HEVC won't play on target device → check codec compatibility (H.264 has broadest support)
• !Audio out of sync after WTV to HEVC conversion → try re-muxing with a different container format
• !HEVC quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
• !File size increased converting WTV to HEVC → lossless or higher-bitrate outputs naturally produce larger files
