Wavefile, BeSweet, FRC 25000 to 24988

[tivi]

Hi all,

just a short question to find out, that I am not wrong.

At the time it is not possible to convert a wavefile's
framerate, using Besweet, from 25000 to 24988.

True?


Thank you very much,

Why would you want to ?

[tivi]

Hi KpeX!


I have to..... I own two VHS tapes of the same movie.
I captured one of them through firewire to my computer.
From the other tape I only recorded the audio track.

And now, after some "theory" I found out, that the
second audio has to be FRCed to be in sync with the
movie.....

But, FRCing with BeSweet only produces noise....

BeSweet.exe -core( -input "C:\track.wav" -output "C:\track-New.wav" -2ch )-ota( -r 25000 24988)

THX Ramirez.

But that's exactly what i did.....

[Ramirez]

Hmm... Works like a dream here, perhaps you have some probs with your software setup.

[tivi]

Strange.....

Did you try to convert to 24988?
When I try to change the frame rate to 24990, it works.
Converting to 24988 does not....

BTW, I use BeSweet v1.5b23 and GUI 0.60.

[KpeX]

Can we get a :logfile:

[tivi]

sure.....


It's a logfile created by BeSweet v1.5b22.
V1.5b23 runs on a different computer.
FRC results in both cases in noise....

You are right, 25000>24988 conversion indeed doesn't works (I left PAL>NTSC preset checked by mistake :P) anyway I guess that not all frame conversions are supported, maybe you should try to play with the "-d" option instead.

EDIT:

Try this little procedure, load your movie into Vdubmod, (check "direct stream copy", go to "stream list" and add your audio track, navigate to "video">"rate control" and click on the third radio button labeled "change so video and audio duration match (XX.XXX FPS)" save the movie as *.* .

[tivi]

Ramirez, thank you so much for taking care...


I am now changing the framerate with another program - pity.....

You know, I want to create a DVD with two languages,
(it's my fault, i did not mention that.....) so changing
the framerate of the video would not make much sense.


Anyway - BeSweet ist great!

THX again

It looks like BeSweet just doesn't accept that last digit if it's any value not zero. The BeSweetGUI will run BeSweet with a non-zero last value but it doesn't "stretch" the audio. If BeSweet is run from the command line with the non-zero last value it'll crash. This is probably a bug.

In my case I was trying to stretch audio that wound up being a bit shorter than the video during the capture. I can't just tweak the video frame rate in VirtualDub because I need to reencode the avi file to mpeg2 to burn to DVD and I'm guessing the mpeg2 video needs to be 29.970fps.
