Bengaluru-based startup Rephrase.ai is trying to assist companies create personalised content material by way of machine-generated movies
Moreover advertising and marketing movies, Rephrase is getting used to create edtech programs, video chatbots and A/B testing
Based in March 2018, the artificial media startup is trying to deploy know-how to trace all movies generated by way of the platform to dam piracy
Each couple of months you possibly can anticipate a collage of plain-looking portraits of human faces driving up chatter on social media with the headline asking you to guess which amongst them are actual folks and that are generated by AI.
The approach which permits pc engineers to create these sorts of lifelike faces was invented in 2014 by Ian J Goodfellow, an AI researcher who at that time used to work at Google Mind and now could be the director of machine studying at Apple.
Goodfellow’s seminal paper confirmed how Generative Adversarial Networks or GaNs can make use of two AI fashions to play a sport of cat and mouse — with one attempting to create a picture and the opposite attempting to detect a real one from the pc generated one — to iteratively make AI-generated media extra lifelike.
Constructing on this system, Bengaluru-based startup Rephrase.ai is trying to assist companies create personalised advertising and marketing movies by way of a SaaS dashboard. Rephrase’s tech makes use of pre-recorded audio and video clips of fashions to create multimedia primarily based on the person preferences.
The artificial media startup was based in March 2018 by Ashray Malhotra, Nisheeth Lahoti and Shivam Mangla. That is the second entrepreneurial enterprise of Malhotra and Lahoti, the primary was SoundRex, a startup that labored on reducing latencies in audio transmission utilizing machine studying algorithms. Mangla was a software program engineer at Fb’s Menlo Park headquarters earlier than founding Rephrase together with his IIT Bombay batchmates.
“Nisheeth mentioned to me that he wanted to build an engine which can take text as input and create a Hollywood level movie as output so that we can just take a script and create a movie without ever shooting anything,” stated Ashray Malhotra, who can be the CEO of Rephrase.ai.
Whereas that’s an ambition far out sooner or later when the know-how advances sufficient, the startup’s determined to concentrate on the short-term monetisable purpose of automating the creation of movies for companies the place only a front-facing mannequin speaks right into a digicam.
A SaaS Dashboard Meets Video Automation
Rephrase.ai’s tech is constructed round current footage the place fashions for 10 minutes converse on to a digicam. This helps map facial expressions and lip actions to the speech — at 30 frames per second, this creates a database of 18,000 frames for every mannequin. The startup’s ML algorithms primarily based on GaNs, created by a workforce of six deep studying engineers, use predictive analytics to overlay any audio file on any video within the database to generate a lifelike video.
Because of this a person can simply choose any mannequin on the SaaS dashboard and sort the textual content which the character will then converse. On prime of this base of AI-generated video, a person may also choose costumes, customized backgrounds, caption placements, and select audio from a menu of 40 languages.
“In general circumstances, what you would have to do is first conduct model auditions, then get a cinematographer, rent a studio, shoot and then do post production shoot editing. We eliminated all of those tasks and made the entire process only a few minutes long,” stated Malhotra.
At the moment, the convenience of video creation that Rephrase.ai affords has been adopted for 4 use instances — the first operate of selling movies the place purchasers can ship out personalised advertising and marketing movies to potential prospects, creation of edtech video programs, changing textual content chatbots into video chatbots and A/B testing of promoting movies.
Malhotra stated that Rephrase.ai has created a video course on edtech platform Udemy to showcase what it does within the sector. “Creating video content is a big cost for an edtech company which limits the scalability of the process. We can create hours of video content in just a matter of a few minutes with a simple input which can help edtech companies scale really well,” he claimed.
In digital advertising and marketing, budgets are sometimes small and firms don’t have sufficient time and sources to check out completely different variations of an advert marketing campaign. That is the place Rephrase.ai discovered an issue it may repair. “We help companies create multiple versions of the same video at a very reasonable cost and very, very quickly. And they are then able to run all of these different videos on social media and see what works best for them,” stated the founder.
Whereas pooling in revenues from these use-cases, the corporate plans to additional develop its AI algorithms to progressively add extra variations equivalent to a number of feelings, hand gestures, head actions, completely different digicam angles and dramatically completely different backgrounds.
“With each of these small tech jumps, you’re going to see us get a step closer to the virtual movie idea,” Malhotra stated.
Going through Competitors In Two Markets
Since Rephrase.ai has its eyes primarily on the advertising and marketing content material use-case, it has to take care of competitors from established gamers equivalent to Vidyard, Loom, Wochit, Animoto and Wibbitz, amongst others. Although these platforms too automate video creation at scale with a number of variations equivalent to textual content, background tracks, visible templates and so forth, they’ll’t be used to generate movies of human fashions utilizing AI.
On the artificial media entrance, a London-based startup Synthesia, based in 2017, affords the identical set of options as Rephrase.ai. Furthermore, it additionally boasts of a funding kitty of over $four Mn and a stellar checklist of clientele equivalent to Reuters, WPP, McCann, BBC and Accenture. Compared, the Bengaluru-based startup has raised $1.5 Mn in seed funding led by Lightspeed Ventures and AV8 Ventures — and has but to disclose any main purchasers.
Nevertheless, generative AI startups are nonetheless within the early levels and most of those supply textual content, voice or animation-based options. Whereas GPT-Three is the greatest instance of the textual content producing AI, voice synthesis is one thing that corporations like IBM, Google, Amazon and Apple have mastered over time with their textual content to speech engines.
Utilizing AI to create human-like characters is mostly completed by making a 3D character and projecting actions of physique elements on it, which ends up in the uncanny valley drawback the place the fashions look very near actual people and but there’s a distinction which may make folks really feel uneasy.
The best way this drawback is handled is VFX the place a number of digicam angles are shot of a mannequin after which the footage is reconciled with the animated character which seems to be an costly affair. “Now instead of something which used to cost a hundred thousand dollars, and require dedicated VFX artists, we’re able to make it affordable for everyday use cases across a bunch of other different industries and across a bunch of different sized companies,” stated Malhotra.
Dealing With The Hazard Of Faux Movies
Each firm that creates media utilizing AI is confronted with the issue of deep fakes — content material that may be actual to the purpose of deceptive the viewers into believing in its authenticity. In keeping with a Georgetown College report, the Russian disinformation ploy within the 2016 US presidential election might be a template for each international governments and non-state actors to make use of AI/ML deepfakes that destabilise nations.
Because the accepted definition of deepfakes is proscribed to swapping facial expressions, physique actions or dialogue between two characters, Rephrase.ai know-how doesn’t technically fall beneath the deepfake class.
However what’s to cease a person from manipulating a whole lot of hours of digicam dealing with footage and audio tracks of political leaders to create a pretend video? Malhotra stated that the startup doesn’t permit any political content material to be created on its platform and companies are made to signal an settlement to not use it for any ulterior motives.
Moreover, all requests for video creation are monitored by the corporate as of now and because the variety of movies produced on the platform scales up, Rephrase.ai would deploy know-how to trace all of the content material generated. Furthermore, although corporations are allowed to onboard footage of their very own gross sales representatives to the platform, every of these are vetted by the startup.
“As founders we left our earlier jobs because we see that there’s a big enough commercial value for good uses of this technology. And that’s where we want to build the company,” stated Malhotra.
