Pixel Aspect Ratio

alifftudm95 wrote on 5/23/2019, 12:19 PM

So I was playing around with VEGAS Pixel Aspect Ratio that turns the video into wider view, making the ratio somewhat 21:9 like cinema aspect ratio. But I often do it manually by changing the width and height of the main project. Since VEGAS has this simple toggle button for me to choose the pixel aspect ratio, this save me lot of time.

But doesn't matter I do it either manually or by using the pixel aspect ratio, my video that was shot on 16:9 will remain its original aspect ratio. Is there any method or trick to make the whole video in timeline change the aspect ratio base on the project settings? I have to manually change the video aspect ratio by using Pan/Crop. I set mine 1920x810 which is roughly to 21:9 aspect ratio.

If I'm not mistaken, entire video sequences in the adobe premiere timeline will automatically change its size base on the project setting.

I would set the trackmoton(s?) to this and render the file with the same settings to get your 21:9 output

It still the same as I have to set the timeline manually. I would prefer everything is automatically followed the project settings without touching the track or pan/crop to resize the ratio.

You may crop, stretch/squeeze, change display dimensions or have black borders to change Display Aspect Ratio. That's the only one we ever see.

Changing Pixel Aspect changes storage dimensions to save space, that's all. Anamorphic is automatically changed to unity upon playback, meaning you will never see it under normal circumstances.

More great articles for you on Wikipedia.

Thank you! Make more sense now, still learning in filmmaking :D

"I have to manually change the video aspect ratio by using Pan/Crop."

The manual process can be made much less tedious if you save Pan/Crop presets...

...then selectively apply them to some or all the events on the timeline. Here, I was using the presets to quickly zoom into a UHD project. Delivery was 1080.

The easiest way (for me) to make a 21:9 aspect ratio project of 16:9 recordings, is to use the cookie cutter with the following settings as video output FX.

Yea, I saved mine as preset 1920x810. Which I still need to toggle through the settings

Wow this is smart, Thanks for the tricks!
