gamera versus betamax

a completed project by weltraumbesty / krp

This is a rather straight-forward project, very much what it says on the tin; an archive of the 8-film Showa Gamera series from its earliest domestic home media releases.

why?

Though letterboxed widescreen film transfers became the norm in Japanese home media releases from a relatively early date, earlier home media editions were more often sourced from flat 16mm television prints (and occasionally even abbreviated 8mm and 16mm digests). These editions, for better or worse, showcase the films as they were presented, seen and enjoyed in the decades between their original release and the advent of home media and television presentations in the original aspect ratios. In the case of the Gamera series these flat pan-and-scan elements have been entirely out of circulation since the middle 1980s. I believe they are worth preserving.

the tapes:

This collection is sourced from privately collected and prior rental releases in variably preserved condition, including a full run of the series on Beta cassette and a further two on VHS. The releases in question appeared first in generic cardstock sleeves with Daiei Video Cassette branding (with pertinent film and sales information relayed via printed stickers applied to both the sleeves and the cassettes in question), and were later issued with series-specific branding, including imagery from the films and profile illustrations of the various monster antagonists. All but Super Monster featured a still from Giant Monster Duel: Gamera vs. Barugon as a front cover and a still from Giant Monster Gamera as a back. Super Monster's front cover artworks were specific to that film, and lost the Giant Monster Gamera imagery in favor of a flat blue back cover background. These cassettes retailed for between ¥19,800—¥28,000 (roughly $80—$115 each at the time) and, though apparently sourced from the same elements, present different telecine transfers between the VHS and Beta cassette versions.

the files:

Beta cassettes were captured from a Sony SL-200D Hi-Band Beta Hi-Fi deck (which I imported from Japan some time ago for its excellent automatic tracking capability), while VHS cassettes were captured from a bedraggled Aiwa HV-MX1 multisystem VCR (very good picture, but limited to analog mono sound only) in the case of Giant Monster Gamera and a substandard Toshiba DVR4X combination VCR and DVD recorder (which I generally use for DVD playback and TBC passthrough) in the case of Giant Monster Dogfight: Gamera vs. Gyaos. The first round of captures, from January of this year (2026), were done without the benefit of time base correction. The second round of captures, completed earlier this month (November 2026), utilized the aforementioned Toshiba DVR4X for TBC.

Initial capture work was done using a Blackmagic Intensity Pro 4k PCIe capture card and OBS, resulting in lossless huffyuv + pcm (32/48) source files. These were then two-pass encoded (x264 + flac) in AVIDemux to produce the final .mkv files. The first round of captures was encoded at unnecessarily high video bitrates (10Mbps vs 6.7Mbps), resulting in higher file size for those versions as compared to the more recent ones. Original capture resolution (720x486) and interlacing have been preserved. Files will need to be AR corrected to 4:3 and deinterlaced for proper playback. Tapes are presented as-is, with no supplementary audio or subtitle tracks included.

status:

Completed. Additional files may be added in the future, as time and access to tapes allows, but the primary goal of this project has been accomplished.

The files for Gamera versus Betamax are available at the project's Archive.org page and directory listing. Files are numbered by film release order. Newer captures carry "Redux" in the filename.
