What John means is that Vegas' MP3 capabilities are limited to the registered version (because of outside licenses). They do work very well.

I have registered version.

some mp3 do not import and some do not import completely or have the wrong length ...

this is not really a Vegas issue as it is due to various means of making a VBR mp3 files in most cases ..

just use something else to convert the file to wav file first ...

When i tried to import here come ups another sign : "An error occured while opening one or more files. The file is an unsupported format."

Maybe a badly made mp3. Get Virtualdub and have it copy the file to wav.
Don't worry about the size of your movie. It is the final render that counts.

so i doesn´t matter if i use .wav or .mp3? Is it the same size if i use .wav or .mp3 in the final render? Because all my mp3s won't work

That's right.

The MP3 encoder has to be registered separately.

Try this to answer several questions;

Start a new Vegas project > drag a .wav to the timeline > render it to MP3

If you haven't registered the MP3 encoder you will be prompted there. If you have, after rendering the MP3, drag it to an audio track.

Does Vegas fail to open it's own rendered MP3s?

What everyone has failed to mention is that .wav files are better quality & that's what you want...QUALITY. I find adobe premiere far better with different video/sound formats than vegas, to be honest I only use vegas for it's superb capture qualities.

If you use VBR mp3's it's all messed up (but does play fine). My copy of Vegas has no problem important any type of MP3.

Did you istall a new media player or audio codec/card recently?

Yes i did, i needed it because i am doing a counter-strike movie! But i can try to render that .wav file to mp3 later because i am on another computer right now! Thx for the help!

i cant choose .mp3 when i render it but if i write it after the filename it render it like a .wav file.

Do you have a registered copy of Vegas that you've paid for?

Was biting my lip Chien.........

macsgrafs -
Yes wav is better, if it's an original wav. A converted mp3 to wav will not sound any better than the mp3. Just to clarify to our worried Counter Striker.

And I have to question your Premiere over Vegas statement. Vegas plays almost anything I throw on the timeline - different stills, video and audio formats. Ok, not ac3. That's one of my favourite things with this editor. Give it all your different stuff, mix it together and it does rarely complain.

Plus, when Vegas 4 came out, it let you use many more filetypes then premiere 6 did. Infact, as far as I know (i haven't used PPro) Vegas has always had more support then Premire (the reason pre PPro versions didn't support mpeg 2 is because they didn't consider it a worthwhile editing format. That's straight from one of their tech guys on their forums!)

The other part of macsgrafs comment that seems odd is his praise for SONY's VidCap, which is probably the one part of the Vegas suite that receives more derision than praise in this forum. It's almost like he's got it backwards from everyone else's opinions on which is best.

While my Video app. experience is limited, I've used many audio apps. and Vegas is the ONLY one that let's you simply drag just about any format to the timeline effortlessly.

All others I've used, you must "import" and destructively process formats into a project.

That aside, of course uncompressed formats such as .wav and .avi are best for quality but the OP's quandary started with the MP3 import question.

I'm with Kelly, something's seriously amiss here since there's no MP3 render template nor will it import MP3.

I'll admit I'm a little jaded though after spending hours either remotely connected or on the phone providing support to users only to find they had bootleg copies many times in the past. I'm hoping my suspicions are incorrect and will have to offer a "my bad".

Here's a quick question for Zlashy: are you one of those Counter Strike: Source players who put %n at the end of your name? ;)

(to others who don't know, when you put "%n" at the end of your name in the game the game server would crash causing EVERYONE on the server to get booted. Pretty funny... especially if you don't play the game like me! :) )

No, i am not. :D But i knew the bug :P

download the free audacity and convert your mp3 to .wav, it works for me in .wav.

 

Why .mp3 downloaded from the google drive isn't supported is crazy.

But this is a solution.

Goodluck
