High Definition AVI sample
I’ve seen a sample of a high defintion (720 lines, progressive) AVI with AC3 (Dolby Digital 5.1 surround sound). The quality of the picture and sound was stunning.
Some rough comparisons for how big a 38 minute recoding is, for different quality and type. This is for the lot, sound and video:
- Standard defintion TV recording (MPEG2): 1.5 GB
- Compressed to ok quality MPEG4 (XviD or AVC): 230 MB or 0.22 GB
- The above Hi Def AVI – MPEG4 (DivX) : 1 GB
