Kudos for setting up a proper use case!

But I think you accidently killed this feature request, too.

Explanation:
IMO killing happened by introducing the term "certified". I have troubles seeing competitions in need of finish line equipment *and* willing/able to go with uncertified equipment.
So - IMO again - this ML-feature-to-be has to be certified to be used. Those procedures are not exactly free and AFAIK there are some organizations doing them (for different regions and different sports).
ML is not represented by an organization/company and there is no person with proper authorization to sign a paper.

And industrial/production line usage shares similiar problem: Nobody there to sign and fulfill a contract. Who will be accountable for long-time support?

I understand your view however; Of course such an implementation would never be used in the top of the sport, but I still see many cases where it could enhance the current use of hand timing. In some countries hand timing is used to very high level's of a specific sport. And although a hand timer that is being used could even be "certified", it would be trivial to modify even the sporting regulations to allow for such use of any timing or camera device, provided they just are better than the hand timer. (which is obvious)

The same kind of applies to industrial use. Nobody with proper capita is going to buy canon dslr to support their manufacturing lines. However, again, there are a range of groups that could use such a feature for even actual manufacturing, as long as an insurance company is willing to insure something that the company is required to insure by law. (e.g. third party liability). Students, startups, moonshots etc. could readily use this kind of "technology", and it would still go a long way in my opinion.

Is there someone who knows whether the features I am asking for are possible to be implemented and if not what are the limitations? I imagine the hardware should be capable from a bandwidth point of view. I can only see that there is some fundamental hardware/ SoC -limitations that set a ceiling for a framerate. Is it possible to "overclock" the cmos/cmos driver, and just output the first/middle/last line from the censor to the image processor? What happens if you just ask the camera for a single line of  full frame resolution at 1000fps? What is the maximum shutter speed when filming video?

A similar analogue can be made with film making... Big budget films rarely employ dslr cameras in their films.

Whaaaaat? I missed something?

My bad... I blame google

Hello,

I know what I'm requesting might not be able to be done due to framework and SoC or hardware limitations, but I'll throw it out there anyway. Since there is some effort done to high speed imaging @ 120fps with Magic Lantern, I thought my requirements could be filled with a Magic Lantern powered Canon camera! Basically I am asking if it would it be possible to mimic a finish line camera by reading a single line of the image sensor at 400fps to 2000fps with Magic Lantern? I'm no software nor a hardware expert, but for what I know, maybe it could be possible to read a single line from the camera at several hundred frames per second and either create a video file from the capture of the single line. A image file could work fine too, since the actual required bandwidth isn't that great by modern standards. I imagine maybe the 2nd option would be easier to implement because one wouldn't need to tune the feature to work with a video encoder. Perhaps even RAW video could be shot.

For use cases there are the obvious; cycling races, winter sports, motor racing and athletics. Then there are also more ambiguous uses, for example industrial or production line usage, especially if you can somehow pull the camera feed live. I imagine it wouldn't be too difficult to take it even further than this, even as a timing equipment, since some Magic Lantern supported camera's support a GPS receiver, which could be used for accurate timing of the image/images. I understand timing several hundred images per second would get a lot more difficult, but even getting an accurate time for just the first image would make the camera feasible as accurate timing equipment.

This kind of implementation, even if implemented just half way @ 500fps would dramatically reduce the cost of acquiring and using a high speed line scan camera (finish line cameras with certified hw & sw cost 7-15k$, and industrial line cameras are in the same range)

Thanks
