sound plays too fast now?
I'm going nuts reading these forums, maybe I dont get it, so Ill ask...
Isn't the digital-to-analog audio conversion of the mp2 file in the svcd/vcd done 'independently' from the video? The video is encoded at xxxx kbps & xx fps and the audio at xxx kbps with the sampling freq of xxxxx hz (hz = cycles per second). So its all done in 'whatever' bits of information PER SECOND.
A 10 minute (600 second) clip running at 29.97 fps, reencoded to 25 fps doesnt play in 8.34 minutes (500.5 seconds), it will still play in 10 minutes. So the multiplexed audio track will still play in 10 minutes also. So nothing should sound speeded up or slowed down, it should sould excactly the same, not to mention the original mp2 track should be multiplexed with the reencoded video anyways, since it would only lower sound quality to reencode it again.
I'm open to the fact that I could be wrong, I dont think I am, but please, I dont buy the whole 'converting ntsc to pal (or the other way around) will make a slight change in the audio speed playback', so please give me a little more technical proof, because I am curious if this is an actual fact. And please lets not turn this into a flame war, I'm asking an honest question here.
