I'm just setting up the input capture on timer 2, input capture 4. On page 411 of the reference manual for the CCMR2 register and the CC4S bits, it states "01: CC4 channel is configured as input, IC4 is mapped on TI4 10: CC4 channel is configured as input, IC4 is mapped on TI3".
I'm not sure what TI3 and TI4 are referring to. I've done a search and this is the only place they are mentioned.

You did not tell us, which STM32 are you using.
Luckily, timers are the same across all STM32 :)
Look at the timer block diagram figure at the beginning of the timer chapter; look just before the Input filter & edge detector blocks: TI1..TI4 are internal signals directly corresponding to digital inputs from TIMx_CHx pins.
Unfortunately, the documentation toolchain ST uses to generate pdfs does not preserve the characters in figures, so they are not searchable.
