The lander external view is simulation, but they have a camera (Lander Imager Display) looking downwards that is transmitting live photos every couple of seconds (center, top right on the main screen).

Though it's disappointing to see simulation, it makes sense as there is no external vehicle to capture the live video and stream it. The lander cameras are showing realistic video though.

In principle, it should be clearly stated which is real and which is sim.

can the frames received be stitched into an animation video using some kind of image interpolation algorithm?

They did it officially from ISRO: https://twitter.com/isro/status/1694713817916473530

Nice . I was wondering about the algorithm

There's no footage from the last one as the lander crash-landed on the surface of the moon.

NASA reported locating the Vikram Lander's debris in Dec 2019: https://www.nasa.gov/image-feature/goddard/2019/vikram-lande...

It was mentioned they were receiving footage continuously. I think when all monitors are shown, in the middle you can discern pictures being rendered.

Edit: They called this out now, it seems those are live pictures.

This one has onboard cameras and there are curated videos from other phases of flight at the OP link.

Thank you, I missed that.

Definitely no footage, at most maybe a picture if it lands successfully.

The only footage we have of any spacecraft landing anywhere other than Earth is either from Apollo or the Perseverance skycrane deployment. If they do have footage, it'll be like the latter, retrieved after the fact.

Thats not accurate, there is "footage" of other spacecraft, such as the first soviet venus lander or so

It's simulation for sure. Would there be sunlight to view it live?

Yes. For solar panel purposes they're landing in the lunar day (14 Earth days?).

Edit: At the start of a lunar day, which equals 28 Earth days. (Source: BBC https://www.bbc.com/news/live/world-asia-india-66576580 )

but seriously why would they not? If they have something nice to show of why not? This is publicly paid project (by indian tax payers) that is political in its nature. Why not show as much as possible?
