Evenin' Martin,
Forget the Mbps (Megabits per second), what counts is the resolution of the photos or videos that you take. The higher the resolution (more dots per picture or Frame in the case of video) the more 'dot' information has to be stored = more memory and a faster Mbps rate are needed.
Not to mention the number of frames per second, FPS; you film at! Anything over 25FPS fools the eye and the brain into 'seeing' continuous movement. very high frame rates, up to 50FPS, are only needed if you are filming F1 Hydroplane races or similar!
Sooooo, higher resolution or frame rate means shorter playing time for a given amount of memory, i.e. your micro card. in the camera menu there will be a point in the Video section where you can select the resolution. HD is best !!
Set the camera to HD (or Fine) resolution, record a 5 or ten minute video and check how much space you have left on your card.
Most camera displays will give you this info in terms of 'Time left' at the set resolution. My Sony and Pentax do .
Again, give me the camera make and model and I'll see if I can find this info on the manufacture site.
Bon chance mon ami, cheers Doug
Most cameras also have some fixed internal memory as well as a card slot, with a corresponding Menu point where you can choose where to store your photos or videos.
There is also usually a section in the manual describing the video function and a table of resolution settings versus how long you can record with a given memory size.
These days the User Guide supplied with the camera is often very rudimentary and you are invited to download the full Monty manual from the manufactures website. The 'User Guide' should contain this web address.
Give me the camera make and model number and I'll see what I can find.
Young at heart 😉 Slightly older in other places.😊 Cheers Doug
