  • Sony Vegas Pitch Shift – Bad rendered video – any ideas?

    Posted by Jim Bower on May 20, 2012 at 5:34 am

    Hi Everyone,

    I have googled this for some time now and even read posts here. But now I am having a problem with rendering my Vegas project with Pitch Shift. I apply the pitch shift plugin and everything worked as it should. The problem is, after a successful render, about 4 minutes into a 8 minute video the audio goes bad. Sounds like someone is talking through a walkie talkie or a broken drive through order window. It’s like the audio is jumping around.

    I was able to remove the shift pitch mods and then render the video just fine. Now I am trying to re-render the rendered video with just the pitch shift applied. It’s rendering as I type this, but why is Vegas failing at this? Any ideas? All I have is 3 layers, a video, and 2 audio. I took a recorded screencast from my ipad and I had to cut out some pieces of it, I also cut out some audio, because the screencast that recorded had some missing audio bits to begin with, so I don’t know if this is where the problem started, but it played just fine in Vegas, so I assume it should output whatever it plays as is. Didn’t happen. BUT it did render just fine when I removed pitch shift.

    So 2 questions, is there something I should have done to my audio layer after all my cuts and edits BEFORE applying shift pitch to avoid this from happening?

    Also, I searched long and hard to find the best way to change the voice in this project I am doing. I wanted to change the actors voice but NOT make it appear that the voice was altered. I.E. no chimpmunk or devil. The only way I found to somewhat accomplish this was to use pitch shift and do a max of 1 to 2 on the semitones and then use the Track EQ to bump/change the 4 levels. If anyone knows of a better way, I WOULD LOVE TO KNOW. Something that could change even the sound patterns of intonation on words would be great, don’t know if its possible.

    Oh boy, really need help now. So the video that rendered perfectly fine without any changes to audio was put back in Vegas and re-rendered with just the pitch shift changes and the same result happened. Any ideas what is going on?
