With so much video footage being shot now using mobile phones, the problem of ‘shaky-cam’ creeps in. Thankfully Kdenlive can fix some of it. Word of warning: this is completely hit and miss. You’ll have to tweak sliders back and forth to get the best results. There’s no real-time previewing here I’m afraid.
Avec toutes les vidéos qui sont prises actuellement avec des téléphones portables, le problème de la « caméra tremblotante « s'insinue. Heureusement, KLdenlive peut en résoudre une partie.
Un mot d'avertissement : Ceci est complètement aléatoire. Vous devrez ajuster les réglettes en avant et en arrière pour obtenir les meilleurs résultats. Et, à mon grand regret, il n'y a pas de pré-visualisation en temps réel.
Stablisation Drag your shaky video into Kdenlive as we’ve done before, but don’t drag it down to the Video lines yet. We need to stabilise it first. TIP: trim your shaky video file as much as you can. The shorter the shaky file, the quicker it will render out as a stabilised file. Right-click the video thumbnail and select Clip jobs > Stabilize Up will pop a window with many different sliders.
Destination - this is the name, and location, of the stabilised version of the original file. Options - this is where the hit and hope happens. There’s a lot of things you can tweak in here, but the ones to start with are the smoothing, accuracy and shakiness sliders. Oh, and the tripod slider too for having a reference frame. Add Clip - it’s best to leave the ‘Add clip to project’ option ticked. And click OK to begin the process.
It might seem like nothing has happened, but Kdenlive is now analysing the footage and creating a new video file. If you look below the file name and time, you’ll see a progress bar slowly start to fill up. You’ll also see ‘1 job’ above the list of videos. Clicking here will give you the option to cancel the job(s). When complete, the new video file will be in your list of files for the current project.
That’s basically it. Have a look at your stabilised video and see if it’s better, or worse. Try again. Rinse. Repeat. Conclusion It’s just a shame that it’s not a more visual interface for stabilisation, but it’s certainly better than nothing. Which is what most other video software seems to offer.
