Sky transitions

Hello,

I was wondering if anyone knows of a plug in for Sony Vegas Pro 16 for a Windows 10 operating system that would allow me to move the SKY ONLY very fast in a video. I see this all the time on tv shows and find it very cool to see the clouds zipping by while everything else stays the same speed. Thank you!

What you're seeing is time lapse. Spend a few days or nights shooting a still every 30 seconds (edit: see later comments) to a few minutes apart. Then, place all the stills on a Vegas timeline and make a short video from it.

Then use a mask to blend it with your real time action scene. Sometimes if your sky in your real time scene is a clear blue, you can chromakey.

Ok thank you, so there is no plug in to make it easier lol- I do aerial photography for real estate and thought it would be a cool effect to use on some projects.

No, definitely timelapse. BTW it's MAGIX Vegas not Sony. Been that way for years now.

30 seconds is too long for clouds unless you really want them zipping by warp speed. I find 6-8 second intervals work best. It also helps to leave the shutter just slow enough to have a tiny bit of motion blur present in the image, it makes the lapses look way smoother. To do this you often have to close the aperture (but not all the way, it reduces quality) and use ND filters.

+1, I typically fo 5 second intervals with 1/2 second shutter. ND filters required (6 stop up to 10 stop if bright.)

Or just shoot some clouds with video and speed it up. I did this during a recent storm.

Correct, i get that part but how do you replace the sky in your video with a different time lapsed version?

john_dennis wrote on 7/7/2019, 2:22 PM

Fr0sty and Kinvermark are correct for most phenomena like clouds moving across the sky. I looked at one of my old timelapse projects and I was shooting every 5 seconds.

The result is here.

I'm not working toward an Academy Award, I just spent a pleasant afternoon near the American River while a laptop collected pictures from an old Canon still camera. Not a bad way to spend an afternoon.

Edit: Corrected arithmetic.

@Kimberly-Durecki

You need the same shot (static tripod or motion controlled, e.g., Genie mini) taken first with video, then with timelapse. Then overly them and mask the sky out of the video to let the timelapse clip show through. I think there must be youtube tutorials for this. Check out the latest SYRP promo/instructional videos.

One more tool that you may find useful, and this is to all my fellow lapsers in this thread... LRTimelapse is a lightroom plugin that works magic on a timelapse. It removes any flicker present, and if you have to make any settings adjustments during the lapse, such as during a sunset or sunrise, it smooths those out so you can't see them anymore as well. It's the best way to get those truly pro-looking lapses.

I've been bugging the Vegas team about implementing a feature like this, hopefully one day they'll see enough market potential in it to give it a shot. I know lapsing is a niche thing, but there should be enough of us out there to support the development of such a product... currently no all in one solution exists for timelapse that takes you from RAW import all the way through delivery while offering flicker removal, ramping setting changes, and noise reduction.

To the OP, you'll shoot your video and the timelapse from the same camera, same tripod. Do not move it between shoots or until done. Then use the bezier mask tool to mask out the sky in the normal speed video, and have the lapse video on the track below.
