I think there is bug in PrPro Cs4 4.21 (Or it is just on my system) when improted Mp3 file , the file is loaded and conferm the duration is correct and
I can see the full waveform.
when i place the file on the timeline and play it mute the 2nd half of the file, i have try various mp3 that work with out any problem on PrPro CS2.
I know that is workaround (convert to Wav) and saw a post regarding this issue http://forums.adobe.com/message/2375384#2375384
just wanted to know is it a bug or somthing not work for me.
A bug is only a bug if it can be replicated, otherwise it is a feature. Since it can't be replicated, it is a feature, probably of your source material.
One consideration is that MP3's can contain a lot of "stuff." Some of this "stuff" can prove problematic. With the exception of tiny SFX files, I ALWAYS convert all MP3's to PCM/WAV 48KHz 16-bit, prior to Import.
One of the things that MP3's can contain is album art. Conversion strips that "stuff" out.
Good luck, and I strongly recommend against using MP3's.
PS - conversion will NOT restore all the data that has been lost in the MP3 compression. That is gone forever.
