Switching between tracks works seamlessly via MKV’s built-in audio menu. Sync holds throughout. Subtitle options (if included) are typically English SDH and sometimes the alternate language’s subs.
The rip is well done. Bitrate stays high enough that blockiness isn’t an issue except in a few fast-moving smoke plumes. File size is reasonable (usually 8–12 GB for a 1080p x264). No artifacts like green bands or corrupted frames. Plays smoothly on VLC, MPC-HC, and most media players.
If you’re a fan of the guilty-pleasure 1998 Godzilla – or just want the best possible 1080p version before a true 4K UHD release – this Mastered in 4K x264 dual audio rip is the one to grab. The audio alone makes it worth upgrading from older copies. Just don’t expect Shin Godzilla .
