No doubt. I'm just the type that likes to do a proper risk assessment up front.

I still think if you want us (SC) to have a thoughtful discussion on this topic, it would be helpful for you to submit an example for us to work with (if you haven't already). I think that should include the video clip, the extracted still-frame (the "original"), and the entry as edited for an "Advanced" challenge.

When you originally suggested this I thought it was an invitation to "Go ahead, submit an entry that way and see if we ask for it to be validated". If you're looking for an example set to look at publicly I'm happy to that.

No, I think you should submit the example files via a ticket so we can see what we're (potentially) dealing with, and only enter "traditional" stills for now.

Deal. I'll get you something by the end of the weekend.

OK, but be aware it will probably be other SC members actually looking at the files -- I have a very low-tech setup myself -- and I can't actually promise any specific action ...

If I can provide some insight into how to access the required information I'll make that available as well.

Forgetting about the rules for a moment, why would you want to take a video and then extract a single frame? Simply to have more images to 'choose' from or some other reason?

Waterproof GoPro Case versus destroying my DSLR under-water is one reason I was contemplating bringing this exact discussion up.

Well then, go ahead and submit a ticket with some sample files.

I don't think we're going to have rules which are brand-dependent, so if we can't validate all video we may not allow any ...

Guess that's a valid reason other than the fact your GoPro can take stills every 1/2 second. If a still from video is allowed then I'll be looking to borrow one of the cameras the slow mo guys use.

actually lets ban it, it will probably lead to more water drop and splash shots.

Nope, not looking through 10,000 images for a couple of shots that might work. I'll stick to my set up and take a single frame for my drip shots :) But yes, lets ban it anyway.

I wouldn't think you'd need brand dependent criteria, only something that would detail the required information in the "raw" file provided. Some cameras do not record EXIF data, which is why that is specified already. The equivalent of that would be something that produces a video file that does not contain sufficient creation data to recognize it as an original source. Provided the minimal criteria is met in the source file then brand only comes into play if it does not supply the minimal level of information.

Funny thing is, I found more information immediately available on a MOV file from a Canon Powershot than most current Canon and Nikon DSLR's embed.

That's what I have -- what did you use to view/extract the data?

As would most people I'm sure. However, this discussion is more about sending in the actual video file that would hve some sort of exif data. I think a worry would be that yes, the video might have exif data but selecting a single image from several thousand would make validation as to editing rules pretty difficult as well would it not? The 'original' file submitted would not have exif data so no way to tell if part of another frame had been added to the original.

I'm worrying too much, one for SC to decide upon.

The Panasonic FZ1000 can extract a still from a 4K video, and attaches EXIF data to the output. Other camera producers should pay attention.

And this is where I believe it would be a requirement for the photographer to provide the precise source frame. This can be done in Photoshop CS6 and later as seen in this screen shot...

Time is encoded as HH;MM;SS;Frame and can be input manually so as to go to the precise location of the utilized frame.
