This tutorial covers how to export regular flat videos or images so that you create the perfect thumbnail or export VR content as regular 2D videos.
DeoVR is currently working on automatic thumbnail generation from videos, but for now, exporting from video has been difficult. Shotcut, however, makes things very easy.
First, your video will have to be in the standard VR format, equirectangular, so you might have to first run it through your included camera software.
Then, load up Shotcut and follow these instructions.
Create a 2D flat thumbnail from your VR video
Select the perfect frame :
- Import your video(s) into Shotcut and onto the timeline
- Select your desired clip in the timeline by clicking on it
- In the Filters subwindow, press the “+” sign to add a new filter, search for “360” and select the “360: Equirectangular to Rectilinear” filter
- Navigate to the frame of your choice in the Timeline
Frame the image
- Click on the video preview to drag it and scroll the mouse wheel to zoom in and out
- Frame your image how you want it to look
- To export the frame directly to 1280x720, go to “Settings/ Video Mode” and select one of the HD 720p options (be careful that you don’t render your video in 720p - make sure to revert to the native video mode of your video after saving the thumbnail)
Export as high-resolution PNG
- To save the thumbnail, go to “File”, then “Export”, then Frame”. (There is also the Ctrl+Shift+E shortcut but this may clash with AMD software)
- Save your frame as png
- Now you can import that frame into your preferred image editing software
Create 2D landscape video from your VR content
This can be used to promote your VR content on social media, or if a client requests it.
- Import the video into your timeline
- In the Filters subwindow, press the “+” sign to add a new filter, search for “360” and select the “360: Equirectangular to Rectilinear” filter
- Frame your video the way you want by clicking on the video preview, then click to drag the video and scroll to zoom in and out
- Select your output resolution by going to Settings/Video Mode. Go to the Export tab, enter your preferred encoding settings and export your file
Now you can easily make thumbnails for Deo VR or export regular video from your VR video, for promotion on social media or other purposes.
