השוואה בין שני הפורמטים
אחחח, איך אני אוהבת לעשות את העבודה בשביל עצלנים. הרי בדיוק בשביל זה המציאו את גוגל. האמת היא שגם אני רציתי ללמוד קצת יותר על ההבדלים, אז הנה מה שמצאתי און ליין In terms of video and audio quality, SVCD is in between VCD 2.0 and DVD, using a 2x CD drive to support variable bitrate (VBR) MPEG-2 video up to 2.6 Mbps, and either 1 or 2 MPEG-2 Layer II stereo audio streams (for soundtracks in two different languages). It is also possible to use MPEG-2 Multi-Channel 5.1 surround audio encoding. SVCD can deliver more than 2 times sharper video images (480x576 for PAL material, 480x480 for NTSC - commonly referred to as a "2/3 D1" resolution) than the previous VCD standard . Because of the increased vertical resolution, the interlaced nature of video signal is now also preserved. This results in smoother-looking motion for any video footage that was originally shot with a field-based video camera (as opposed to frame-based film or a "progressive frame mode" video camera). SVCD supports 16:9 (anamorphic wide screen) image aspect ratio. (Actually, it has always been possible to store 16:9 material in anamorphic format - even on a VCD 2.0 disc or VHS tape - but maybe some SVCD players can now also tell the TV set to automatically switch to the right mode by using wide screen signalling methods.) SVCD has extensive support for subtitling and karaoke lyrics color highlighting, neither of which were possible in VCD 2.0. An SVCD video stream can contain up to four independent subtitling channels for different languages. The subtitles are overlaid on the top of the video image in real time, which allows turning them on and off at will. Since the subtitles are stored as bitmap graphics, they are not tied to any particular script or character set. Additionally, SVCD standard supports HTML style hyperlinks, still images (480x576 or 704x576 for PAL, 480x480 or 704x480 for NTSC), playlists/slideshows, multi-level hierarchical menus and chapters (indexing). To sum it all up: SVCD discs can be used to deliver karaoke or music videos, movies, home videos, still image slide shows, product catalogs and games much the same way as VCD 2.0 discs. However, SVCD standard is not a direct superset of VCD 2.0 standard. It is not possible to use VCD 2.0 frame sizes or MPEG-1 video if you want to create a standard SVCD disc. The typical running time of an SVCD disc (with full resolution and quality) is about 35-45 minutes, although it can be extended to over 70 minutes by compromising image and sound quality.
