confused~can someone please help me with this

hi, I've asked quite a few people about the status of the word "change" in the sentence " i hated to see it change". Some said it's infinitive and others noun; however, either one makes sense to me. If "change" is infintive, what is "to see" then? If it's noun, what is "it" then? Also, what is the word "started"in “ most people are fast to stop you before you get started but hesistant to get in the way if you are moving”？　is it the same as with "change" in the first sentence?　Can someone please help me with this？ Also, do tenses in the same paragraph and sentence need to agree with each other? From my understanding, tenses have to agree with each in an essay/article; however, I, sometimes, come across several different tenses in the same paragraph and sentence. For example, tenses in this paragraph “it was Feb 16, 2006, and he was now a mogul skiing gold medalist at the Turin Winter Olympics. Unlike other full-time athletes, he will never have to return to a dead-end job after his moment of glory” don’t match with each other

In addition, tenses don’t agree with each other too in this sentence “Using dehydration techniques I now teach to elite powerlifters, I lost 28 pounds in 18 hours, weighed in at 165 pounds, and then hyperhydrated back to 193 pounds”

Hi ichiro, let's see if I can make myself clear with this... "I hated to see it change" in my opinion change is neither an infinitive nor a noun, it's just the base form of the verb, this happens because of the structure of the verb "see" the structure of this verb is usually like this: "to see s.o do s.t" the verb "do" is neither an infinitive nor a noun, it's just the base form of the verb, just like saying: "I help s.o DO s.t" or "he helps s.o do s.t" it's just base form of the verb due to the structure of the main verb of the sentence.
Now, "most people are fast to stop you before you get started but hesistant to get in the way if you are moving" started here is in past participle, here you could say "you get started" "he gets started" " you get done s.t" or "he gets done s.t" so started is the past participle for "start".
Conclusion: change=base form of the verb "to change"
started= past participle of the verb "to start" which means they are different.
Tenses and sentences do not have to agree, remember that a languge is to complex just to limit it by saying "this grammar rule is going to be like that forever" you cannot limit a language beacuse there's always an exception to any rule
I hope this helps out and just in case s.o=someone s.t=something
