Introduction

Cuvista stabilizes shaky video footage on your PC. Open a video file, save to a new filename, and watch the software do its job. Contrary to other software by default Cuvista will do only one single pass over the input to analyse the video and generate the output.

The software will use GPU acceleration if supported hardware is found, greatly accelerating the process that way. The Cuda platform present on Nvidia grahics cards is used preferably, but OpenCL capable devices are supported as well. No special driver or software is needed to make use of gpu acceleration. Without any dedicated hardware the stabilization process will still be completed, albeit on CPU power alone, which will provide the same result at a significantly lower speed.

Sample Footage

The following video shows side by side the original recording and the stabilized version using Cuvista

Get Started

Get yourself the latest version of Cuvista and stabilize your videos by following the steps

• Click the link at the top of this page to download an installer for the latest version
• Install the application
• Find the entry for cuvista in the Windows Start Menu and click
• Open any video file by clicking the camera button
• Click Stabilize to process and save the new video
• You may uninstall the application via the list of installed Windows Apps

Portable binaries are available in the GitHub repository

Options

Some settings allow to change the process and outcome

• Overwrite: When checked, no confirmation dialog is displayed when overwriting an existing output file
• Device: Select the device to do the heavy computing. Prefer a cuda capable device
• Temporal Radius: How many frames before and after shall be considered to smooth movements. Higher value will generally provide smoother output
• Zoom: Stabilization moves frames around the screen, which may reaveal blank areas. Zooming into the video can hide this moving effect. Set a minimum zoom value and optionally allow dynamic zoom up to a certain maximum value to compensate for violent movements. Dynamic zoom may adversely introduce new moving effects, keep low values
• Background: Fill the void in the background either with a fixed color or preceding frames from the video
• Encoding: Select the device and video format for encoding the output. Can be different from the stabilization device
• Side by Side: Put original and stabilized video side by side to directly compare stabilization results
• Image Sequence: Output a sequence of individual image files rather than a video file
• Live Playback: Play resulting video directly, do not produce an output file
• Limit Output: Stop producing output after given number of frames, useful for testing results

If you want to watch how exactly each frame is moved around to compensate for the shakyness in the input footage, try to setting zoom to -8 and background to some fixed color

Command Line Version

There also is a command line version availabe which provides more advances options

Open a command prompt, go to the installation folder and use the syntax cuvista.exe -i infile -o outfile

Provide the option -h to get additional help
