vidSmooth

This is an Electron app written as a frontend for ffmpeg using the new vid.Stab library. vidSmooth takes an input video and outputs a stabilized version in high quality mp4/h264 format.

Install (0.0.0.2)

Download and install for your OS:

• MacOS (dmg, 140MB)
• Windows (exe, 96 MB)

Features

• Any codec supported by ffmpeg will be supported as an input video (mp4, m4v, avi, wmv, mov, flv, mpg, mpeg, gif)
• Most settings vidStab uses as input are exposed to the user
  • accuracy
  • shakiness
  • smoothing
  • maxshift
  • maxangle
  • crop method
  • camera path
  • tripod mode
• The user has the option to select a portion of the input video and create a stabilized sample before committing to the entire video

Issues

• By nature of any smoothing algorithm, often the frame will have to zoomed / cropped to produce a consistently smoothed video. As this is the case, a higher resolution video will give a better result
• When creating a sample clip, the progress bar only updates on 33%, 66% and 100%. If a long clip is selected or the client machine is slow, the user might think nothing is happening when it actually is.
• Occasionally ffmpeg will choke on a video input type, but since there is no error control built into this app, it will just stop responding
• When the smoothing settings are too agressive, vid.Stab will 1) over-crop a large portion of the video an/or 2) introduce edge artifacts in an attempt to interpolate video data
• If tripod mode is set to on, but the input video pans away from a subject, the result is that the edge pixels get smeared across the video and no further useful video will be displayed
• Dramtically shaking videos that are heavily smoothed can have a jello effect, depending on the type of sensor used in shooting the footage
