The creators of a short video using Sora technology explain the strengths and limitations of AI-generated videos
OpenAI’s video generation tool Sora surprised the AI community in February with smooth, realistic video that appears to be well ahead of the competition. However, there are a lot of details unnoticed of the rigorously choreographed debut – details that were filled in by a filmmaker who was given advance access to create a short film starring Sora.
Shy Kids is a Toronto-based digital production team that has been chosen as one of only a few by OpenAI for the production of short movies essentially for OpenAI promotional purposes, although they got considerable creative freedom in creating an “air head”. In fxguide visual effects news interviewpost-production artist Patrick Cederberg described “actually using Sora” as part of his work.
Perhaps the most significant takeaway for many is that this: while OpenAI’s post highlighting the short movies allows the reader to assume that they were created roughly fully shaped by Sora, the reality is that they were skilled productions, equipped with solid storyboarding, editing, color correction, and publish work equivalent to rotoscoping and visual effects. Just like Apple says “recorded on iPhone” but doesn’t show the studio setup, skilled lighting, and color work after the fact, Sora’s post only talks about what it allows people to do, not how they really did it.
The interview with Cederberg is interesting and quite non-technical, so in the event you are in any respect interested, go to fxguide and read. But listed below are some interesting facts about using Sora that tell us that, while impressive, this model is maybe less of a step forward than we thought.
Control is the most desired and most elusive thing at this moment. … The only thing we could achieve was simply hyper-descriptive tooltips. Clarifying the character’s attire, in addition to the type of balloon, was our way of ensuring consistency, since from shot to shot/generation to generation there just isn’t yet a feature arrange to offer full control over consistency.
In other words, things which are easy in traditional filmmaking, equivalent to selecting the color of a character’s clothing, require complex workarounds and controls in the generative system because each shot is created independently of the others. This could change, of course, but it surely’s definitely rather more labor intensive lately.
Sora’s prints also needed to be watched for unwanted elements: Cederberg described how the model routinely generated a face on a balloon that the foremost character has for a head, or a string hanging from the front. They needed to be removed by mail, one other time-consuming process in the event you couldn’t get a prompt to exclude them.
Precise timing and character or camera movements aren’t actually possible: “There is a little bit of temporal control over where these different actions are happening in a given generation, but it’s not precise… it’s kind of a shot in the dark,” Cederberga said.
For example, synchronizing a gesture equivalent to a wave is a very approximate and suggestion-based process, unlike manual animations. And a shot that appears like a panorama pointing upwards at a character’s body may or may not reflect what the filmmaker wanted – so on this case, the team rendered the shot in a vertical orientation and cropped it in post. The generated clips also often played in slow motion for no particular reason.
In fact, the use of on a regular basis film language equivalent to “swipe right” and “tracking shot” was generally inconsistent, Cederberg found, which the team found quite surprising.
“Scientists weren’t really thinking like filmmakers before they turned to artists to play with this tool,” he said.
As a result, the team performed a whole lot of generations, each lasting 10–20 seconds, and ended up using only a handful. Cederberg estimated the ratio at 300:1, but of course we might all be surprised at the ratio for a regular photo.
A band, actually he made a little behind-the-scenes video explaining some of the issues they bumped into in the event you’re curious. Like much AI-related content, the comments are quite critical of the whole project — though not as insulting as the AI-powered promoting we have seen pilloried recently.
One last interesting caveat concerns copyright: If you ask Sora to share a Star Wars clip, he’ll refuse. And in the event you attempt to get around this “man in robes with a laser sword on a retrofuturistic spaceship” problem, he may also refuse because by some mechanism he recognizes what you are attempting to do. She also refused to take an “Aronofsky-style shot” or a “Hitchcock zoom.”
On the one hand, it makes total sense. However, this begs the query: If Sora knows what it’s, does that mean the model has been trained on that content to raised recognize that it’s infringing? OpenAI, which holds its training data cards near the vest – to the point of absurdity, as in CTO Mira Murati’s interview with Joanna Stern – he’ll almost definitely never tell us.
When it involves Sora and its use in filmmaking, it’s definitely a powerful and useful gizmo as an alternative, but its purpose just isn’t to “create films from whole footage.” Already. As one other villain famously said, “that will come later.”

Sequoia increases its 2020 fund by 25%
Sequoia says no going out, no problem.
According to data from the Silicon Valley enterprise capital giant, the worth of its Sequoia Capital US Venture XVII fund increased by 24.6% in June at the top of 12 months. Pitchbookwho analyzed data from the University of California Regents Fund.
Sequoia’s margin is notable since the fund hasn’t had any exits yet. This can be a positive development for the 2020 fund vintage, on condition that after the uncertain valuations of 2020 and 2021, this yr’s funds usually are not expected to perform well for any VC. The mismatch is probably going resulting from high AI valuations giving risks a way of an economic recovery that has yet to bear fruit in other sectors. Sequoia is an investor in high-growth artificial intelligence corporations including OpenAI, Glean and Harvey, amongst others.
Sequoia has raised over $800 million for Fund XVII, which closed in 2022.

Revolut will introduce mortgage loans, smart ATMs and business lending products
Revolutthe London-based fintech unicorn shared several elements of the corporate’s 2025 roadmap at a company event in London on Friday. One of the corporate’s important goals for next yr will be to introduce an AI-enabled assistant that will help its 50 million customers navigate financial apps, manage money and customize software.
Considering that artificial intelligence is at the middle of everyone’s attention, this move shouldn’t be surprising. But an AI assistant could actually help differentiate Revolut from traditional banking services, which have been slower to adapt to latest technologies.
When Revolut launched its app almost 10 years ago, many individuals discovered the concept of debit cards with real-time payment notifications. Users may lock the cardboard from the app.
Many banks now can help you control your card using your phone. However, they’re unlikely to supply AI features that might be useful yet.
In addition to the AI assistant, Revolut announced that it will introduce branded ATMs to the market. These will end in money being spent (obviously), but in addition cards – which could encourage latest sign-ups.
Revolut said it plans so as to add facial recognition features to its ATMs in the longer term, which could help with authentication without using the same old card and PIN protocol. It will be interesting to see the way it implements this technology in a way that complies with European Union data protection regulations, which require explicit consent to make use of biometric data for identification purposes.
According to the corporate, Revolut ATMs will start appearing in Spain in early 2025.
Revolut has had a banking license in Europe for a while, which implies it may offer lending products to its retail customers. It already offers bank cards and personal loans in some countries.
Now the corporate plans to expand into mortgage loans – some of the popular lending products in Europe – with an emphasis on speed. If it’s an easy request, customers should generally expect immediate approval and a final offer inside one business day. However, mortgages are rarely easy, so it will be interesting to see if Revolut overpromises.
It appears that the mortgage market rollout will be slow. Revolut said it was starting in Lithuania, with Ireland and France expected to follow suit. Although all these premieres are scheduled for 2025.
Finally, Revolut intends to expand its business offering in Europe with its first loan products and savings accounts. In the payments space, it will enable business customers to supply “buy now, pay later” payment options.
Revolut will introduce Revolut kiosks with biometric payments especially for restaurants and stores.
If all these features seem overwhelming, it’s because Revolut is consistently committed to product development, rolling out latest features quickly. And 2025 looks no different.

Flipkart co-founder Binny Bansal is leaving PhonePe’s board
Flipkart co-founder Binny Bansal has stepped down three-quarters from PhonePe’s board after making an identical move on the e-commerce giant.
Bengaluru-based PhonePe said it has appointed Manish Sabharwal, executive director at recruitment and human resources firm Teamlease, as an independent director and chairman of the audit committee.
Bansal played a key role in Flipkart’s acquisition of PhonePe in 2016 and has since served on the fintech’s board. The Walmart-backed startup, which operates India’s hottest mobile payment app, spun off from Flipkart in 2022 and was valued at $12 billion in funding rounds that raised about $850 million last 12 months.
Bansal still holds about 1% of PhonePe. Neither party explained why they were leaving the board.
“I would like to express my heartfelt gratitude to Binny Bansal for being one of the first and staunchest supporters of PhonePe,” Sameer Nigam, co-founder and CEO of PhonePe, said in a press release. His lively involvement, strategic advice and private mentoring have profoundly enriched our discussions. We will miss Binny!”
