lower framrate

[Subwars]

hi i'm sure this has been talked about and how to do it somewhere but i've done a dozen different searches and been reading several threads for over an hour now and havn't gotten anywere

basicly i'm trying to rip some cartoons and wanting to like cut the framerate from 25 fps down by around half that i'll trial and error to i find a good speed that looks normall but is actually less saving size

i've tried using xvid's cartoon mode i couldn't get xvid to work for me with 2pass's no matter what i did (i'm not an xvid user) but i did get it to work as a single pass so i just finished that and the fps are still @25 so that didn't lower them like i thought it might

i need some direction i've riped hundreds of movies but have never done small cartoon eppisodes i'm going to be doing all of the dragon ball z episodes so if anyone else has done them any tips on the best settings for it would be great... i was hoping to aim for around 100mb per eppisode with the frams being cut down i couldn't see it being a problem i just have no idea how to go about doing it

please help

Hi-

It's easy to cut the framerate in half (or whatever percentage you want), but I would not recommend it. Even anime, which is, indeed, usually drawn at framerates other than 24fps, often has passages at 24fps, and lowering the framerate will leave some parts playing jerky.

Here are some ways to do what you want:

SelectEven() (http://www.avisynth.org/Select), or SelectOdd()

ChangeFPS(12.5) (http://www.avisynth.org/FPS)

ConvertFPS(12.5) (http://www.avisynth.org/FPS) (for YUY2 only)

Decimate(2) Read the Decimate portion of the Decomb manual included in GKnot.

Just edit the .avs to add a line using the method you choose.

This can also be done in VDubMod without reencoding. Go Video->Frame Rate->Process Every Other Frame (Decimate by 2).

XviD's Cartoon Mode is for something completely different from what you want.

Not really, only with keyframe only videos. For obvious reasons MPEG4 video with P and B frames would causes serious trouble just stripping every other frame. In these cases VDub just selects the first half of the frame sequence between two keyframes.
