Exported Videos are a Tad Wide

Now, this isn't a large issue. But it's something I've noticed with Visionlab as well as Final Cut Pro. The videos I export are very slightly widened. Video settings and everything are always correct and are exported in H.264. The strange thing is that this issue is corrected when I compress it with VideoWrap. Now again, this isn't something I'm going to pull my hair out about. But I'm just simply wondering what is causing this very slight proportion change.

You might be using the wrong dimension settings. Be sure that the number of pixels match up when you create a project. That should help.

Hmm, that seems more than a tad wide to me. I'd suspect a pixel aspect ratio issue first off. If the resolution isn't changing, then the aspect ratio of each pixel has to be, so have a look at those two areas first to see what might be amiss.

They're almost certainly not. smile

The things you want to check are the pixel aspect ratio and the resolution. One or both of them is wrong, which is causing the stretching.

Indeed Tarn, but what confuses me is that VideoWrap, as you can see, fixes the problem. So I'm not sure if this is something that I can use to my advantage. If my video settings were set correctly, the video would be exported with the right proportions. However, if VideoWrap continues to do what it does, would it not perhaps make the video thinner than it should be? crazy

Depending on the specific format you are using on VideoWrap, pixel aspect ratio may be one of the settings you have to choose. If so, then VideoWrap is probably just changing things to what they should have been to begin with. Videowrap is going to set the pixel aspect to a fixed set of numbers which you select, regardless of what the aspect is on the clip coming in.

I think.
