probs with odd frame rate conversions

[uk_dan2k]

i got a 2 cd version of blow, i've converted the film and combined it for dvd use.
the films fine, but the audios on both cds are 23.976, i've demuxed them which where mp3.
Once i converted it to wav the frame rates change.
Im trying to convert them to 25fps, and to format .ac3
i've used besweet gui, and ac3 machine, tried putting in excact frame rate to 25fps but get cracking noise problem.
So i used ntsc->Pal option, this has got me closer to the frame rate

i want, but now: -
cd1 = 25.001 fps
cd = 25.139 fps

problem is i need combine the 2 audio files to combine with the video and it wont combine cuz of the different frame rates, and i cant combine em using besweet or ac3machine cuz of the bug it has with cracking noize.

i've got some new software, timefactory, soundforge and cooledit 200
i've heard ya can fix it with 1 of these but dont know how, how can i fix it using 1 of these and using them frame rates.
big thanks!

What the heck?!
You got 2 CDs, you combine them to one AVI in direct stream copy mode in VirtualDub(Mod), which framerate do you get? is it in sync?

[uk_dan2k]

i can't combine the 2 films because for some reason the audio streams are different in each cd, both mp3 encoded at 23.976fps but some how diffent, error msg comes up when you click append avi blah blah, but goes to quick to read.
i'm sure its error about the audio streams dont match 100% positive.

error: cant append movies, audio streams have different data formats!

i used tmpgenc to encode the audio, es - audio only option for dvd, pcm audio. Then i used besweet gui to change the odd frame rate to 25fps.
now cd 1 works and = 25fps but
cd 2 works = 25.001fps

and i still cant combine them cuz of the 00.1 dosnt match bollox

[Awatef]

When you say both files have 23.976fps, this is not a frame rate issue anymore, it's a bitrate or sampling rate issue.
Give technical details about the sound of the first avi and the sound of the second one.

[uk_dan2k]

i found a way to fix it.
the sound on both cds was 23.976fps, mp3 vbr, diffent bit rates.
i demux'ed both of them and encoded them to wav, using tmpgenc to es stream audio only - dvd.
Then changed frame rate from odd rate -> pal and it worked
:>
thnx anywayz

[Awatef]

that's about what I was going to suggest after giving me the technical details, because it certainly has nothing to do with the framerate.

Hope you done a correct framerate conversion (acceleration in VirtualDub to 25fps in direct stream copy mode, then acceleration of the wav sound with TimeFactory with a 95.904% ratio)

[uk_dan2k]

yea i used direct stream copy, but didnt know how to use other software like timefactory, used besweet to go from odd frame rates to which ever it would work with ntsc or pal, then if it was ntsc, ntsc->pal

[Awatef]

besweet is good, but it doesn't correct pitch, so voices get a bit modified. timefactory does perfect pitch correction, so voices sound the same, but if your sound file is too long, you may not be able to convert it to the end.

you know what? you make me laugh everytime you say odd framerate :D
23.976fps is no odd framerate, it's standard NTSC-Film framerate. It's the framerate used on every NTSC movie DVD encoded in progressive mode (most of them).

[uk_dan2k]

no when i say odd framerate i dont mean standard 25 or 23.976, here are some examples of what i had: -

25.359
25.001
22.404
23.977
23.999

i am interested in using timefactory, but arn't sure how to use it, i saw some percentage or something you use, but dont know if you source has be certin frame rate.
how would you used it to change frame rates from ntsc->pal and vice versa?
Also is there a calculation u can just to to work it out for any framerate?

big thanks

[Awatef]

the calculation is very simple: (source framerate / target framerate) x 100

So, for NTSC 23.976 to PAL 25:
(23.976 / 25) x 100 = 95.904%

And for PAL 25 to NTSC 23.976:
(25 / 23.976) x 100 = 104.271%

cheers

what for 29,970 to PAL ?
