Converting 24fps to 25fps using AVISynth???

[sungod93]

Is there a way instead of using convertfps() to convert 24fps to 25fps??? The reason why im asking is that i do not want blended frames in my footage. I know there are ways such as assumefps() but that makes the audio out of sync

Is there that i can make an extra frame which is interlaced??? so it can make 25fps???


Thanks

If you use AssumeFPS you have to change the length of the audio.

This should do the job (get the most recent version of MVTools)
source=last
backward_vec = source.MVAnalyse(overlap=4, isb = true, pel=4, search=3, idx=1)
forward_vec = source.MVAnalyse(overlap=4, isb = false, pel=4, search=3, idx=1)
source.MVFlowFps(backward_vec, forward_vec, idx=1)

you can try
assumefps(25, sync_audio=true)
ResampleAudio(48000)

to change the audio length.

ChangeFPS doesn't blend frames, and keeps audio in sync.

Another easy way is to use DGPulldown. The effect should be the same as when using ChangeFPS (repeated fields), but no need to reencode.

thanks everyone for your input. ALthough changefps makes the video jerky. Im yet to try the code that "thetoof" posted

You have to pick your poison...

A) 2 repeated fields per second (two little stutters)
B) 1 repeated frame per second (one larger stutter)
C) speed up the audio and leave the pitch 4% higher afterwards
D) speed up the audio and correct the pitch, introducing audio artefacts
E) convert the frame rate of the video using motion compensation, introducing video artefacts

C is by far the most common, for obvious reasons; E is the least common because it's the slowest, and the results can be really ugly when they go wrong - depends on the content.

If you want interlaced, you should have used ConvertFPS(50) followed by interlacing, that's option A above.
