IMPORTANCE OF 1/60 AT 60i

[sundance44ANCE44]

can someone explain the importance of using 1/60th when shooting at 60i?
Ill be shooting our ships reunion (navy) in san diego in october and would like to do a nice job on the dvd were giving to all the members. ive been dialing in some presets for the xl2 and coming along nicely with those but what about this 1/60 thingy

thx in advance for any input

I think 60i will give you a sharper image then progressive. It also needs less light. A 1/60 sec is the ideal speed its identical to the field rate. There are two fields in every frame. Slower will reduce sharpness and may cause blured images, too fast and the image will strobe.
BTW I'm going to a ships reunion in october in San Fransico The USS Wm V Pratt. DLG-13/DD44. What did you serve on?

No, the XL2 is natively progressive so its interlaced footage actually has less resolution than its progressive footage. Still sharp though. Shutter speed doesn't have anything to do with sharpness, it adjusts the amount of motion blur that are present. Higher shutter speed=less motion blur.

Tin Cans Are Great, Small Crew, Tight Nit Group. I Always Maintained We Should Have Gotten Submariners Pay, Seems We Were Under Water More Than Above

Well Then If Shutter Speed Reduces Motion Blur I Would Guess That Filming In 24p Must Be Terrible If Subjects Are Moving ??

Thanks for defining motion blur as opposed to sharpness, Jade. There is a condition called jutter that can happen if your subject is moving to fast in 24p

I wisely enlisted in 68 a month before the Tet offensive. Wanted to save Vietnam from the commies. Was lucky to get on the Pratt a new ship at the time. 512 ft long, rode much better then some of the smaller ships. Cought a break from steaming when we blew three boilers. Made by Babcox and Wilcox same company that built three mile Island.
Did you ever see the movie The Bedford Incident (DLG-113) Wm V Pratt DLG-13. Hmmm. It's a classic movie stars Richard Widmark and Sidny Portie'. An interesting rewrite of Moby Dick.

3 At Once? Thats Really Unusual, Sounds Like You Put Into Dry Dock For Some Re-tubing

There was an inquery as to what happened. Possibly poor yard work. Damage control was hosing down the stacks on the way home. I really didn't know much about the boilers. Had the good fortune not to be in the boiler rooms much. Sounds like your pretty salty, got to work on the New Jersey. What's "TAD Work"? What was your rateing?

[sundance44ANCE44]

Tad (temporary Additiional Work) Its When You Get Reassigned To A Different Vessel For A Period To Help Them Out With A Problem. I Was A Mr2 (machinery Repairman).. We Were Trained To Make Or Repair Almost Any Part On A Ship (with In Reason Or The Capabilty Of Our Shops) Dont Know How Salty I Was, I Used To Live On Saltine Crackers For The First Few Days Till I Got My Sea Legs And Quit Heaving Up My Lunch.

Shutter speed and frame rate are two different things, right?

[Huy Vu]

yes.
