Here's a sample video demonstrating cinematic slow motion video using the Sony NEX-5N and Sony Vegas Movie Studio Platinum 11 (a mouthful, isn't it?). Below, I explain how to get it.
This was filmed with the 18-55 kit lens for the NEX-5N. The first three clips were taken using the 24fps 24Mbps AVCHD setting (I absolutely love the video from the NEX-5N in this mode). If you want cinematic video, you set your camera on manual exposure (it's not as scary as you think), set the shutter speed to 1/50s (cinematic is 1/48s, but who's counting?), and then adjust your aperture until exposure looks right--the histogram option on the camera can help here. For the first clips, which were in sunlight, even at ISO 100 I needed to put a polarizer filter on my lens to cut out half of the light. If you're looking for a polarizer for your NEX, you don't need a circular polarizer--just a linear polarizer (less expensive) because their autofocus is based on normal contrast.
For the slow motion clips in the video, I shot using the 60fps 28Mbps AVCHD setting. Again, make sure the camera is in manual mode, but now you now set the shutter speed to 1/125s and adjust aperture as necessary. This makes it so that when you slow the video down later you still get the cinematic effect that matches the 24fps video clips.
In Movie Studio (or Vegas), you make sure your project is set to 1080p24 by choosing "Match media settings" in the video box when starting the project and then browsing to a 24fps clip.
To make the 60fps clips slow motion, you put them on the timeline, right click, and choose "Properties". In the properties window, change the "Playback rate:" from 1.0 to 0.4. You'll have to resize the clip by dragging the left side of it to the left to see all of it because it's now 2.5x as long as it was.
This video was shot for a music video for my sister, who is currently battling skin cancer and wanted to go for one last run before starting treatments. Unfortunately, EMI has blocked the full video on youtube because it has a Coldplay song in it, but I thought I'd post this how-to video while I try to work that out. The soundtrack here is David Gray - New Horizons.
I had to reupload this because the upload to youtube option in movie studio resampled to 30fps (boo!) and for some reason the audio wasn't coming through either. Sorry about that!
