According to wikipedia, 16:9 SD video formats are also valid BD-Video formats https://en.wikipedia.org/wiki/Blu-ray#Video
SD 720 × 480 29.97i 4:3 or 16:9[d] (anamorhic) 720 × 576 25i 4:3 or 16:9[d]
The Create BD Format contains 720 x 576/ 25i/p and 720 x 480/ 29.97i/p
Please verify if this these are SD 4:3 only? The wikipedia table lists only SD interlaced as valid SD BD-Video format
I just send Phyllis our yesteryear whitepaper from 2010 (creation date), and yeah, it only lists sd interlaced formats. BUT some formats marked with "*" , they are not in spec yet playable by some hardware. from cinelerra/bdcreate.C static struct bd_format { const char *name; int w, h; double framerate; int wide, interlaced; } bd_formats[] = { // framerates are frames, not fields, per second, *=not standard { "1920x1080 29.97i", 1920,1080, 29.97, 1, ILACE_MODE_TOP_FIRST }, { "1920x1080 29.97p*", 1920,1080, 29.97, 1, ILACE_MODE_FAKE_INTERLACE }, { "1920x1080 24p", 1920,1080, 24., 1, ILACE_MODE_NOTINTERLACED }, { "1920x1080 25i", 1920,1080, 25., 1, ILACE_MODE_TOP_FIRST }, { "1920x1080 25p*", 1920,1080, 25., 1, ILACE_MODE_FAKE_INTERLACE }, { "1920x1080 23.976p", 1920,1080, 23.976, 1, ILACE_MODE_NOTINTERLACED }, { "1440x1080 29.97i", 1440,1080, 29.97, -1, ILACE_MODE_TOP_FIRST }, { "1440x1080 25i", 1440,1080, 25., -1, ILACE_MODE_TOP_FIRST }, { "1440x1080 24p", 1440,1080, 24., -1, ILACE_MODE_NOTINTERLACED }, { "1440x1080 23.976p", 1440,1080, 23.976,-1, ILACE_MODE_NOTINTERLACED }, { "1280x720 59.94p", 1280,720, 59.94, 1, ILACE_MODE_NOTINTERLACED }, { "1280x720 50p", 1280,720, 50., 1, ILACE_MODE_NOTINTERLACED }, { "1280x720 29.97p*", 1280,720, 29.97, 1, ILACE_MODE_NOTINTERLACED }, { "1280x720 25p*", 1280,720, 25., 1, ILACE_MODE_NOTINTERLACED }, { "1280x720 24p", 1280,720, 24., 1, ILACE_MODE_NOTINTERLACED }, { "1280x720 23.976p", 1280,720, 23.976, 1, ILACE_MODE_NOTINTERLACED }, { "720x576 25i", 720,576, 25., 0, ILACE_MODE_BOTTOM_FIRST }, { "720x576 25p*", 720,576, 25., 0, ILACE_MODE_NOTINTERLACED }, { "720x480 29.97i", 720,480, 29.97, 0, ILACE_MODE_BOTTOM_FIRST }, { "720x480 29.97p*", 720,480, 29.97, 0, ILACE_MODE_NOTINTERLACED }, }; so yeah, seems like sd 16:9 missing. easy to add I wonder if we should modify 1440*1080 presets to also be wide always? How it looks now {if source is hdv unscaled} in real (HD) TV connected to BD player ?
If so, SD 16:9 interlaced are missing, while SD progressive are invalid? -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
