This looks great, however, things like rolling shutter or video wipes/transitions will be interesting to see how it handles that. Also, all of the sample videos the camera is locked down and not moving, or moving just ever so slightly (the ants and the car clips ). It looks like they took time to smooth out any excessive camera shake.

Intergrading this with Adobe's object tracking software (in premier/after effects) may help.

Huh, I thought this couldn't be true, but it is. The first time I noticed annoyingly fast cuts was World War Z, for me it was unwatchable with tons of shots around 1 second each.

So sad they didn’t keep to the idea of the book. Anyone who hasn’t read this book you should, it bares no resemblance to the movie aside from the name.

Loved the audiobook

This is great. I look forward to when cell phones run this at 60fps. It will hallucinate wrong, but pixel perfect moons and license plate numbers.

I look forward to VR 360 degree videos using something like this to overcome their current limitations, assuming the limit is on the capture side.

I know two movies where the book is way better, Jurassic Park and Fight Club. I thought about putting spoilers in a comment to this one but i won't.

The video of the owl is a great example of doing a terrible job without the average Joe noticing. The real owl has fine light/dark concentric circles on its face. The app turned it into gray because it does not see any sign of the circles. The real owl has streaks of spots. The app turned them into solid streaks because it saw no sign of spots. There's more where this came from, but basically only looks good to someo…

Is this considered a reincarnation of the 'rest of the owl' meme

Video quality seems really good, but limitations are quite restrictive "Our model encounters challenges when processing extremely long videos (e.g. 200 frames or more)". I'd say most videos in practice are longer than 200 frames, so lot more research is still needed.

If you're using this for existing material you just cut into <=8 second chunks, no big deal. Could be an absolute boon for filmmakers, otoh a nightmare for privacy because this will be applied to surveillance footage.

At 24fps that's not even 10 seconds. Calling it extremely long is kinda defensive.

10 seconds is what, about a dozen cuts in a modern movie? Much longer has people pulling out their phones.

Freal. To the degree that i compulsively count seconds on shots until a show/movie has a few shots over 9 seconds then they "earn my trust" and i can let it go. Im fine

At 30fps, which is not high, that would mean chunks of less than 7 seconds. Doable but highly impractical to say the least.

7s is pretty alright, I've seen HLS chunks of 6 seconds, that's pretty common I think.

6s was adopted as the "standard" by Apple [0].

For live streaming it's pretty common to see 2 or 3 seconds (reduces broadcast delay, but with some caveats).

The average shot length in a modern movie is around 2.5 seconds (down from 12 seconds in 1930's). For animations it's around 15 seconds.

Huh, I thought this couldn't be true, but it is. The first time I noticed annoyingly fast cuts was World War Z, for me it was unwatchable with tons of shots around 1 second each.

Batman Begins was already in 2005 basically just a feature length trailer - all the pacing was completely cut out.
