Any ideas on how this was done?

Hello,

Just wondered if anyone knew how this would've been done?

There sure must be a fairly easy way to do it other than the one that spring to mind, which would be to rub out or keyout certain elements and replace the background frame by frame. The only thing that leads me to believe that there's an easier way is that the fact the football match was not done under controlled conditions, meaning it wouldn't have been shot with this effect in mind. I can understand them keying out certain elements, but how on earth did they preserve or reconstruct a non existent background?

A lot of roto work. There is no easy or quick way to do this, with it looking good at least. Actually, it might not be too difficult. But it certainly isn't something you can do quickly.

For the Heinz commercial, I'd check this out:

As for the soccer (football) footage, it's likely a combination of roto work and cloning the field to fill in the space. There have been many commercials over the past few years that have enhanced actual sports footage from games with VFX. This is probably even harder to accomplish simply because it wasn't shot on a controlled set for the specific effect.

Thanks for the reply and the links, it very helpful. I figure this was possibly how these were done, but since these two adverts appeared at pretty much the same time (on TV) I wondered if perhaps there was a new plugin or something that I was unaware of that aided the cloning process. The football (soccer) one is what perplexed me though, due to the uncontrolled environment and the sheer amount of time it'd take. Also I figured you'd able to see the rotoscoping as the frames moved in real time, simply due to how difficult it would be to match it frame to frame.

Yes there is software that is geared towards replacing and cloning from tracked frames to make life easier - look at Imagineer Mokey and search for their "lobster tutorial"
