Once upon a time, back in 2013, was Vine. Pioneers in the looping video clip (6 seconds long), shot through the phone camera, it was labeled the Twitter video app, and not only because the latter company bought the former before its launch. Fast-forward to 2024, Vine service is discontinued, but looping videos are still popping up every day through Instagram Reels, YouTube Shorts and obviously TikTok. Yet with audio loops that don’t playback seamlessly. Is there a way to easily cut a perfect loop out of the track chosen to craft the perfect looping package?

Struggling with minimum audio options

What better companion to a looping video than a perfect sounding loop playing back seamlessly along with the visuals? The problem is, while editing a video to make it loop indefinitely does not require any technical skills other than pasting the same video as many times as you want, things are different when audio loops are concerned. With a little planning for the recording, it’s easy to film the beginning and end with the same action, position, and lighting, to ensure seamless playback. It may require several tries but it remains humanly and manually achievable. Let alone some video editing software allow to play a clip in reverse, when you place it immediately after the original clip it results in a Vine-like seamless looping effect without even aiming for it in the first place.

When it comes to adding audio to complete the looping package, things will turn very differently. Tutorials advise avoiding jarring cuts in the audio, and considering using seamless loops to match the video. But with a stylized waveform for the better or no waveform for the worse, the user is left blind with no visual way to select in and out points that will play back seamlessly. No other option is offered than choosing the portion of the track to use on the video, regardless of the looping potential or the measures integrity. Same goes for software integrated or designed for social short-form video editing, where the user is left with ridiculously basic audio manipulations. As a consequence, most of the time the audio track playing with the video will have different beginning and ending parts, creating a completely unrelated scene to the video. It ruins all the efforts deployed to craft the looping effect visually speaking.

Let the algorithm do his magic

These days, AI is assisting content creators to lower down as many entry barriers. Propelling the creative process to a whole new level and allowing just like everyone to craft professional sounding content.

At Ircam amplify, among many innovative tools, we tailored an algorithm to the very specific task needed to complement a looping video: identify all the perfect loops from a track. We’re already offering this “never thought it was possible” feature to casual and hobbyists musicians through their favorite digital audio workstations and DJ-mix softwares. On Instagram, TikTok, and YouTube, all the perfect loops could be offered on-screen to the creator, up to the selection of the one of their choice. Just add the final touch by applying automatic time stretch to lengthen or shorten the loop to match the exact duration of the visuals, and you’re in for a perfect looping and sounding video.

With the video and audio-enhanced hypnotic effect, users will be hooked to the content and will stop scrolling. The engagement rate will be boosted and due to the looping nature, the content is likely to be played several times, without the user noticing it, all the more with seamless looping audio.
