hey i again tried editing and now i think there was something wrong with the file as when i made an export with other file wiht size of 37 gb it exported in 4min 40 sec and the scrubbing and preview was all smooth it was a 4k H.264(HEVC) footage and yea i only got beachballs for a second or so while opening and closing imovie do you think this just normal?
Nothing to do with your original question but why are you exporting as Best (ProRes)?
ProRes is only intended for saving projects for re-editing.
It is not for videos that are to be watched on TV, Computer, YouTube etc.
ProRes creates massive files that can be manipulated easily during editing, especially by low powered computers.
Sorry for the delay in answering but I have been walking in the snow in the hills.
High is probably the best setting especially if you have a lot of fast motion. Medium and Low will often give results just as good and produce much smaller file sizes.
There is no hard and fast rule, it's a matter of trial and error to see what suits you.
Sometimes just one corrupt video clip can bring a computer to its knees. That could be what caused your problem.
If all is back to normal you need not do an SMC reset.
Since everything appears normal, no need to do the SMC reset. However, it is so easy to do it wouldn't hurt, since you just bought your computer. That way you will know that everything is set correctly. It is just a matter of rebooting while holding down certain keys.

i am new t do this and i thought pro res is the highest quality because it was making the file most large, is high the maximum setting one can , can you tell me some difference here?
can you please also tell if its normal and just read my comment to the answer above and please tell your views.
hey
do you still think i should do a smc reset?
Looks normal to me. You can tell by playing the shared movie and seeing if it is good quality.

i know its silly but can you please tell me what SMC reset will do to my machine and do i have to take any backup to do it ? and in brief words kindly tell what is it?
It looks like you can't reset the SMC on M1 Macs because there is no System Management Controller to reset!

Ian,
Ha! Didn't know that about the M1.
