VPS 21 b.315 video 180 degree rotation questions

Hello:

I occasionally get 180 degree rotated videos, for some baffling reasons, but lately because I have two cameras mounted on one tripod both using USB-C plug-in mics. Until another mount adapter arrives, the one that is a phone has to be rotated 180 degrees so the USB mic doesn't obstruct the other camera.

I figured out two methods to rotate them to the correct orientation. Both seem to take about the same rendering time (about twice the duration of the video).

1) First method used was to click on the fx icon in the video timeline and select Scene Rotation. I am doing something wrong (aside from getting lost) because sometimes I get a wide view with rotation options around X & Y axis, and other times I get a large video frame view with crop, offset and rotation options. Second discovered method was to simply right click on the single video frame preview and rotate 90 degrees twice. About half (4 of 9) the videos did not rotate. I had only checked a couple to verify they did rotate, but I found a way to foul it up. I think I had this problem earlier when correcting camera orientation by a couple degrees. I seem to have a problem determining how to 'apply' an edit step I set up. I am apparently missing a step because I don't know what makes the change 'active'. There is no preview of the edit process (plugin?) chosen, so I go right to Render-As.

Am I revealing above a step I keep forgetting between entering the plugin options and 'applying' them before Rendering-As?

2) Is rendering necessary? Save and Save As only seem to allow a project form like .veg .

 

Thank you

I just noticed something else.

The phone videos before rotation are described by MediaInfo as 20 Mbps 29970/1000 = 29.97 fps

After rotation in VPS and Rendered-As Internet 1080p 29.97 fps, the bit rate (understandably) is 12 Mbps, but 30000/1001 = 29.97 fps, which just seems peculiar (why it changed from 29970 to 30000, necessitating a different division to get to 29.97).

I'll just repeat the tedious rotation step again & see if I figure out what I'm doing or not doing.

Try right-clicking the 180 event and choose properties. Go to the "Media" tab, and then change the "rotation"

You can also change them all using a script. Here's an example script:

 

If you want the "file" to be actually right-side-up, then you would have to render it. Save/Save As saves the PROJECT file - i.e. everything you have on the timeline - and is a VEG file.

Thank you, JETDV.

0) The first re-rotation via two 90 degree turns came out ok. I can see how I could have clocked 90 then 90 clockwise, canceling instead of doubling the 90, with my eyesight. (I always wonder why there is Braille on drive-thru bank ATM's. But that could be me and my laptop soon!)

1a) Dumb question: What is an event in Vegas Pro? I am biased by my view of the event I recorded at as being an event.

1b) Never mind. I was going to ask "What's a keyframe" but it's probably not needed for rotation. Or I don't know that yet.

1a, anything on the timeline is an "event". Drop one video clip onto the timeline and you will get one video event and one audio event.

1b, you don't need keyframes to rotate. However, a keyframe allows you to change settings over time. It will start with the values of the first keyframe and change across time to the values of the next keyframe (and keep changing if you have even more keyframes at different values)
