I'm soon going on a canal boat trip and I wanted to create a timelapse of the boats travel.

I've obviously only got one shot at this, so I wanted to know what is the best method for calculating the right interval to take each frame at. I know the speed limit of the canal and want to create a video that is comfortable to watch (I've seen examples on youtube that are either too fast or too slow).

  @mattdm I suppose that is subjective, like a lot of photography, although it would be fair to say that some time lapses move at an uncomfortably quick rate (like trying to watch a video being fast forwarded at x64). Too slow and you end up with a real time video, which is also not the desired effect.

  Are you taking a series of stills at intervals, or are you using a built-in timelapse feature of your camera? I ask because it may impact answers -- for example, taking stills gives you the option of stitching them together differently (or at different rates) afterward, whereas the built-in timelapse mode is more of a one shot deal.

If you play the video at 30 frames/s, taking one picture/second is a 30x speedup. If your boat sails at 3mph, the time lapse at one picture/second will be a simulated 90mph. How much of a road can you see driving a car at that speed?

Taking the problem by the other end, figure out your "cruise" speed when in a car, divide by the boat speed. This is your "acceptable speedup". This speedup is your timelapse image interval multiplied by the framerate of the playback (20-30fps).

Of course if you want to shoot the whole cruise (say 3 hours=10000s) and make that a 10mn video (600 seconds) then you have to take 12000 pictures, roughly one picture/second but it can be a bit fast.

Keep in mind that the fjord cruise is taken from high above water in a wide fjord, so the feel of the speed is much less and you can use greater speedup factors. This would also be true if you drive your car in a desert (vs. in a forest or downtown). But picturesque waterways are seldom in a very open landscape.

Last, shooting too fast may induce more wear in the camera, and require more storage(*) and/or battery capacity but you can drop frames to slow down the final video. If you are too slow when taking the pictures, you can't fix it later.

(*) Of course for a time lapse, you may set your camera to a lower resolution or lesser JPEG quality.

  Often the bigger downsides of going too fast are battery life and storage capacity. Not knowing the hardware we don't know whether it will charge on the go at all, or whether the OP has the means to do so.
