GOLDWAVE PAL TO NTSC AUDIO CONVERSION

[mouland69]

I FOUND USING THE TIMEWARP BUTTON ON GOLDWAVE WORKS PERFECTLY ON AUDIO COVERSION
JUST PUT THE RE-ENCODED M2V FILE LENGTH IN THERE AND GOLDWAVE DOES THE REST THEN RE-AUTHOR.

Remember to watch the change in pitch as well, so your voices do not sound too high or too low after your conversion, if the time warp change is too drastic.

[mouland69]

i have found that the pitch is altered by goldwave

unless you know different Tommy?

[Tommyknocker]

No, I thought you had to make sure the pitch is not changed after a time warp. If it does change, you have to put it back.

The pitch is changed anyway. If you compare the exact same DVD in PAL and NTSC you will see that the PAL DVD is 4.1% longer, and the audio has a pitch in increase of 4.1% as well. So when you time warp the audio, don't preserve the pitch it is not needed. 4.1% is not enough of a difference to be noticable.

To convert use this rule: Goldwave does audio to the accuracy of .999. For example a 1:30:999 audio clip is 1:31 minus 1 thousands of a second. But most video footage is represented to 1/30th of a second accuracy. So for example a 1:30:29 video clip is actually 1:30:967 when shown in goldwave (or most other audio editors). So to convert:

original video - 1:30:25:15 would be:
- 1:30:25:500 in Goldwave
To get the fraction devide the last 2 digits of the the time shown in your DVD or video authoring app by 30 and use the first 3 digits after the decimal.

Yeah but usually when you convert PAL to NTSC you slow the framerate down to 23.976fps from 25.000fps ... not from 25.00fps to 29.970fps

So if I encode at 23.976fps with 3:2 pulldown does the 1/30th second thing count or what?
