Supposedly bilinear is best for downsizing and bicubic for upsizing. But as far as I have seen bilinear is always too blurry, and soft bicubic almost as much. So I just stick to sharp bicubic, even though it gives largest filesize.

Depends
Depends on the movie to which one i use but mostly i try and stick to neutral bicubic. Bilinear too soft and sharp bicubic too sharp. This is a "rough" guide for me. Of course depends on what you find visually pleasing
Noisy movie - bilinear resize My file size is too large - bilinear I've reached 640 x ... and still have bits left - sharp bicubic So to answer your question - for me it depends on the source but i try neutral resize first and see if it looks good or if i can reach a nice rez b4 i try other resizing. |

as a rule of thumb i would estimate: max filesize with sharp bicubic will be 30-40% higher than with bilinear, the others lie in between. meaning that e.g. if you get a comp-check-perc of 50% with sharp bicubic you might reach about 65% with bilinear. the picture will be more blurred but the codec macroblocks will be less visible. for a perfect rip you need the correct balance of these 4 factors: compressibility - bitrate - resolution - filters. and a litte experience wef. |
