hi all.
i've been making some 1 CD (i can't stand switching CDs) SVCDs with TMPGenc and have been getting outstanding quality from it (like, better than my early attempts at Divx 3), but have a niggling question that maybe somebody more in the know than me could shed some light on.
most DVD standalone players i've come across occasionally go a little strange with open-GOP material, freezing frames and whatnot. so i've been encoding everything closed-GOP for SVCD. at low bitrates this leads to a small but annoying problem - "blinking" between GOPs, in that the last frame of a GOP and the next I-frame are different enough to cause a slight jolt in otherwise smooth motion.
i'm wondering if it's significantly better for bitrate and visual quality to just encode in open-GOP to get rid of this problem? (i assume here that the blink will be smoothed out by the last 2 b-frames)
