• Source: WEB-DL means it was ripped directly from a streaming service (likely Amazon Prime or a Dutch platform like NLziet). This is preferable to a cam or HDTV capture, as there are no channel logos or commercial breaks.
• Resolution (720p): Acceptable but not impressive for 2016. On a 27" monitor or TV viewed from 6+ feet, it looks fine. However, pixel-peeping reveals soft textures and occasional macroblocking in dark scenes (of which there are many—the film is dimly lit). A 1080p release would be superior; given the film’s low popularity, this 720p may be the only surviving pirate copy.
• Codec (x264): Robust and widely compatible, but the Katmovie1 encode likely uses a moderate bitrate (probably 2500-3500 kbps). Fast-moving water or foliage exhibits slight compression artifacts. No HDR, no 10-bit color.
• Aspect Ratio: Presumably 2.35:1 (check file – sometimes WEB-DLs get cropped incorrectly). This one appears to retain the OAR.
