PSP Special - good way to convert 25fps to 24 fps
For whatever reason, the one frame rate that the psp still doesn't handle is
25fps. This is a right pain for us European users.
Saying this, we do now have 24fps, which means we can now convert our footage
without any perceptible difference.
The guys on the doom9 forum first pointed me towards using
AssumeFPS in my
avisynth script. This does not chop out or add in any frames. It speeds up (or
slows down) the frames, meaning that you dont actually change any of the frames.
According to avisynth.org, this is how they show 24fps films on PAL televisions,
so sounds good to me.
This is my avs script:
avisource("c:\video.avi", audio=false)
LanczosResize(368,208)
assumefps(24.000)
you can either copy and paste this, or download it from the main video page with
the other files. (coming soon)
as usual, double click the avs to make sure it loads up in media player classic,
if it does, all is good.
next, belight to change the audio from 25fps to 24fps.
load in your wav, mp3 etc. as per normal
Then to get your 25fps to 24fps (to fit with the 24fps video from the other page) click the advanced settings button at the bottom. under sound touch, tick convert frame rate from and put 25000 in the first box and 24000 in the second (see pic)
click okay, and then transcode your audio file.
once its done, you can mux into your 264 video file using megui under tools -
muxer - mp4 muxer
make sure you set the fps to 24 in the video FPS drop down. add your audio
file, set output file and press queue. then go to the megui queue and click the
start button.
you should then end up with a nice mp4 at 24fps. I personally use quicktime to
check the FPS, probably a better way, but i have at last foud a use for QT ;)
