Rendering causes video to de-sync with audio

Question

So, I'm a fan of making lets play videos. I got everything all recorded with my face cam and a separate audio track to put over that. I synced up the tracks so that they both match up and I have the better audio for my voice instead of what my camera picked up. So, the audio is perfectly synced up with the video. However, If I use any of the render settings like Render In to Out, it causes the video clip (just from my camera, game play footage is just fine) to become de-synced with both audio files. The original clip and the one recorded with my mic. Even stranger. Both audio tracks line up perfectly with each other, the video clip just seems to have moved and I cannot figure out why. I also think that rendering during export works perfectly fine without any kind of distortion (not that I have tested it to make sure). Any theories as to why the program is acting like this?

Answer 1

glad that got to the bottom of it, yeah, you can copy a clip and then paste attributes like the last commenter said to fix the distort issue. you might also try removing the distort and basic motion attributes if you're going to your native codec and haven't animated or blown anything up. but just for future reference, there is no special default final cut sequence setting. whenever you start out on a new one, you should double check to see what kind of sequence you've created. three ways to go about that (there are more):
1) the most basic way is in the Final Cut Pro -> Easy Setups... menu option, or if you want more options, then Final Cut Pro -> Audio/Video Settings... option. those both control the same things, but in different ways. play around in that if you're not familiar with it. but what you set there will be the "default" for new sequences that you create.
2) if you've already got a sequence in your project that you know is correct, you can duplicate that then delete all the stuff in there and start with that.
3) if you fire up a sequence, then drop a clip in that matches the native codec you want to work with, Final Cut will ask if you want to change the sequence settings to match the clip (unless you've turned that warning off). that'll ensure that you're working in the native codec of your footage, if that's what's desired.
you might want to start fresh with a new sequence after having done that and then pasting everything you've done into that as opposed to changing the sequence settings on the other one. it might work fine, but it also could have some glitchiness if you don't start with a fresh sequence. final cut is badass, but sometimes a little tempermental when you start tweaking the technical settings (even if you get it right).
