Vegas Pro v.21 Build315 rotating video and aspect ratio

Hello:

In the past I inquired about having problems with phone video rotating 90 degrees. I now realize I am having an apparent aspect ratio change.

I use Vegas Pro to straighten videos and occasionally adding vignette.

I have not been able to use Vegas Pro to 'call' audio editing functions via Sound Forge Audio Studio 17 with the ease I can open a an MP4 video in SF17 and do audio edits and save as MP4 again.

So I do the audio editing in SF17. About 80% of the time, the re-rendered videos are rotated 90 degrees after re-rendering. I was told it is probably due to the phone encoding orientation incorrectly. It has been happening with two different phone.

So I use Scene Rotation in Vegas Pro to correct the 'sideways' videos. What I realized is that most of my videos do not fit the screen after a -90 degree Scene Rotation is applied. When the video orientation is corrected, it is "too tall", and the person's head is cut off. I am hoping I am missing a setting while setting up the Scene Rotation so I can apply Scene Rotation without corruption the proportions. It's unfortunate I experience video rotation during post-audio-enhancement edit, and another deformation during Scene Rotation.

Have I described enough to possibly identify what I am missing during the Scene Rotation setup? All I change is rotation from 0 to -90. But the axis of rotation that is displayed looks like the end result. That supports the probability the Scene Rotation is doing exactly what I am telling it to. There probably is problem that I am still having severe learning curve issues recognizing the types of changes I need to make. The aspect ratio may be screwed up by the unexpected video rotation by SF17. I am trying to keep this question as a Vegas Pro one because the rotation correction is only possible with VP Scene Rotation.

10/12 of my videos are rotated 90 degrees counter-clockwise after rendering post-audio-processing

Thank you

Murray

If you rotate the video using Picture in Picture, you can adjust the size of the rotated video to fill the preview screen from top to bottom in the PIP dialog. You can use the corner handles to resize, or use the resize setting in the PIP dialog box.

I'm not sure if that's quite what you're looking for, but I do this all the time.

@MURRAY-LESHNER Hi, right click - Properties on the event on the timeline - Rotation to correct your videos.

When you start recording with your phone make sure you're holding it in the correct orientation, if you start recording in portrait 9:16 & then change the orientation to landscape 16:9, it will carry on recording in portrait 9:16 mode.

It's easy to not have the phone turned in the correct orientation by starting filming with the phone laid flat (flat-ish, the screen pointing up to the sky) & the phone has chosen portrait instead of landscape. You need to hold the phone vertical in either portrait or landscape.
