Ask HN: Why do cameras stop recording after 30 minutes?

#1
Some say it's a technical limitation for heat management, memory management. While some others say it's to escape the additional tax that applies if a camera is classified as a video camera, the latter being defined as something that records beyond 30 minutes.

What's the true reason?

Like most head scratchers, it’s EU taxes.

The import taxes are higher on video cameras than still cameras, so they artificially limit the length of videos you can record to avoid being classified as a video camera.

> Video camera recorders are subject to import duty of 4.9% or 14%, still image cameras are duty free.

Some still cameras with video features also do actually lack in heat dissipation department and may really shut down because they overheat. Sometimes earlier than said 30 minute limit kicks in.

And say you use slow memory card in your otherwise capable camera... I have one here, which is allowing me to capture, depending on subject, 4-15 seconds of video. It just cant write stuff onto memory card fast enough and fills its memory buffer and then its done. With proper fast flash card, same camera runs up to 29:59 and with certain tweaks, until flash card is full.

The fact is when you are recording a good quality video you never go over a few minutes of recording. So usually it doesn't bother film makers too much.

If you're recording a live opera it's a problem but then you usually have much higher quality gear without the limitations of a DSLR.

So this is like Sony adding Linux as an option to the PS3 to make it a "general computing device" instead of a "game console" and getting a lower duty percentage?

What if you are recording a conference or a lecture? May easily go over 30 minutes; does not always need theatrical quality.

Spain used to have an extra import tax on home computers with <=64KB RAM. One manufacturer got around it by including an extra 8KB chip on a daughterboard (not electrically connected at all!) to increase the RAM to 72KB and avoid the tax.

That may explain why it is exactly 30 minutes, but, despite some counterexamples, that we don't see more product differentiation enabling the consumer to choose between a camera with the limit and an "upgraded" model (i.e. the same camera with the limit disabled) suggests that underlying that the manufacturer recognizes that the consumer would rather buy under-specced hardware that can't handle much more than 30 minutes of recording than pay more for a design that had the engineering effort to handle unlimited recording put into it. Those who truly have a need for unlimited recording are likely to want something video-centric in design anyway.

I expect the answer is all of the above and more.

Use a $500 video camera rather than a $5,000 DSLR setup?

Earlier quoted context omitted.

5,000$ DSLR’s take better video than $500 video cameras.

So I think it’s just price discrimination. They want people to buy 50,000$ video cameras not 5,000$ DSLR’s.
