60i vs 30f - Premeire CS3 - i still just dont get wich one to use

[SimpleSurfer]

Ok, i know this has been covered a thousand times but... i still havent found my answer... 50 on one side of the fence 50 on the other....

so heres my thing:

i primarily use my Canon XH A1 camera for 2 things...
1) HD TV show - set in hawaii, there is plenty of indoor and outdoor footage... 99% of the time we use soft 3 point lighting
2) event videography... 99% of the time its tragic lighting... too dark with some rediculous window thats horribly placed in my shot... i.e. right behind the bride and grooms table in reception.

so heres my question, ill try to word this properly so that next time someone googles this problem, they will find this post.

1) How noticable is the verticle resolution decrease for 30f?

2) What benifits does 30f have in low light situations?

--2b) If shooting 30f, can i lower my shutter to 30 with out choppy footage?
(when i shoot 60i with a shutter of 30, i notice severe chop)

3) when i create a new project in Adobe Premiere Pro CS3, my only option is 30 frames. am i dropping a frame with out acctualy deinterlacing?

4) often times when im hand held, i will be a bit shakey, will switiching to 60i will that maximize my ability to slow down the clip in order to have a long enough shot thats not shakey?

5) is 30f better for publishing American NTSC dvds? the frame rate of a ntsc dvd is traditionaly 29.?? frames per second. logic would tell me that shooting a progressive image at the closest frame rate possible.

6) which is better for broadcasting HD TV in the USA, 60i vs 30f?

7) which is better for Canon XH A1 Web Based FLV Video? (vimeo.com youtube.com)... i think i can answer this one due to a really fabulous video on adobe.com that explains that shooting 30f will increase quality when exporting 15 frames per second flv video for youtube. please correct me if im wrong. (i will dig the link to that article and post it next)



again, i know its been covered... but, its the responses are too all over the place for me to understand exactly my problem. im certain after reading many of the posts from multiple forums, that a consice clear post will enable people to find the answers they are looking for with out too much drama. if DVXuser will allow me to edit my post, i will reformat this post with the answers to these questions. the pros will flame it, but the newbies will rejoice. i think it would also be very benificial for people who have similar questions to post them here so its all covered. if you know the andswers of common questions reguarding this topic, please also post them.

Thank you VERY much for helping me clear this up.

i found this to be extremely useful when trying to understand the difference between 60i and 30f on the canon xh a1. Progressive Vs. Interlaced is explained really well here, but the video is geared towards web video. i dont do much web video, so i dont really know how it pertains to my questions.

1) How noticable is the verticle resolution decrease for 30f?

Not very.

2) What benifits does 30f have in low light situations?

None that I know of.

If shooting 30f, can i lower my shutter to 30 with out choppy footage?

Lowering your shutter to 30 will introduce more motion blur. It will appear slightly less choppy, and not as sharp. Lowering the shutter will also allow more light into the camera. This can be useful in low light situations. There shouldn't be any choppiness when shooting 60i, unless the shutter get's very slow.

3) when i create a new project in Adobe Premiere Pro CS3, my only option is 30 frames. am i dropping a frame with out acctualy deinterlacing?

I'm not sure what you mean here. Are you referring to 29.97 ntsc frame rate?

4) often times when im hand held, i will be a bit shakey, will switiching to 60i will that maximize my ability to slow down the clip in order to have a long enough shot thats not shakey?

60i will produce the best slow motion on the A1. The progressive modes aren't the best for slow motion. You can get good results using After Effects or Twixtor. If you plan ahead you can shoot all your shots progressive, and the shots you want slow you can shoot interlaced.

5) is 30f better for publishing American NTSC dvds? the frame rate of a ntsc dvd is traditionaly 29.?? frames per second. logic would tell me that shooting a progressive image at the closest frame rate possible.

There is no better. It's a choice on how you want your footage to look. 60i will look like live video, the way your eyes see things. Like your local news. 30p will have a slight progressive look. Think soap operas. And 24p will have the cadence of a film camera. Just about every movie you've ever seen has been shot at 24 frames a second.

6) which is better for broadcasting HD TV in the USA, 60i vs 30f?

24p. Again it's a personal preference. I don't see alot of 30p on tv. Mostly 60i and 24p.

7) which is better for Canon XH A1 Web Based FLV Video?

Progressive modes are better for web video. Again I prefer 24P, I'm yet to use 30p on my A1.

I think you need to decide the look you want each project to have. There is no right or wrong way. Shooting progressive requires more careful camera work. Quick pans and shakey footage will appear choppy. 60i is a bit more forgiving. I prefer the look of 24p, as do most of the people on this site. But it's personal preference. But I will say that shooting 60i on the A1 is pretty nice because the image is very sharp. Happy shooting.

I'm actually wondering about this as well. I have a shoot coming up destined for the web. But, it is sports footage. I have always found progressive (24f) looks way better than 60i on the web, but sports don't look right at 24f. So I guess I'm wondering if 30f is the happy medium between the two for web based sports. Does the motion translation of 30f rank right in the middle of 24f and 60i, or closer to either end of the spectrum?
