Who uses F1?

Most posts, uh, every post if about F5 (understandable! its the DVX main thing)
But who uses F1 here and why?
 
I use F1.... but its totally reprogrammed to a 24pa setting. Have never used the 60i.
 
You can always reprogram any of your F scene file setting so you could make F1 whatever you want. That being said, I do actually leave it at default (everything at default, norm, 60i). The reason for that is that sometimes you might want to shoot 60i. Granted, I've actually never EVER recorded 60i with this camera (whoa, I never really thought about that until now) but if I ever did, let's say if I wanted to do a wedding video and thought the 24p strobing effect would be too distracting, then I could just click 60i.
 
I just filmed a art festival and decided to go for the video look. f1 default. I was amazed by the results! So vivid and crisp. Such quality..... it made me think...
I always use f5 and frankly, on TV it does'nt impress anybody, on the other hand people ask me.... whoa! what did you film that with? It looks bloody great....
DVX100B f1!
I will use f5 whenever i shoot a short, for work...f1 all the way!
 
I find that as soon as I switch the camera to 60i, it really looses a lot of sharpness. Anyone else notice this? I am talking about just changing the scan method from interlace to progressive and changing nothing else in the scene file. It just looks like everything has gone slightly out of focus.

I'm not sure but I'm guessing you meant when you switch FROM 60i to 24p. I'm not sure if the sharpness decreases. Actually if anything, I think it should increase since you're going from interlaced (which splits the frame up) to progressive.

I think what you might be talking about is the inherent light loss that comes with 24p. When you switch to 24p, you lose about a stop of light. That makes your picture look darker which can make you preceive to lose sharpness.

To test this out, I did a little trick where I adjusted the shutter speeds of 60i and 24p respectively. For 60i, i put it as close to 60 (the default) as I could which was 60.3. For 24p, I put it at 24 because when you do that, you GAIN a stop of light, which basically means the brightness is equal to that of 60i. So I did that, pressed the shutter button and switched back and forth between 60i and 24p (for each, it'll have it's different respective shutter speed). Looked pretty identical in sharpness to me.
 
Yes there's a noticeable, significant resolution drop when going from progressive to interlaced. Which is why 720p can look every bit as high-def as 1080i -- because progressive is sharper than interlaced.

Interlace involves a vertical blur to prevent interline twitter. But it results in about a 30% resolution loss. Progressive doesn't have to do that, so it stays pristine and sharp.
 
F1 for F1

i use it when i shoot interviews for ABC. they request 60i @1/60th a second. Drop frame timecode.
 
How can 50i (my case) loose sharpness?
f1 is for vivid crispy sharp pics... the video look i understand
I notice f5 much less sharp... more... movie like! that is why we use f5

I liked the quote f1 for f1

good definition!

Does anyone use 30p?

Yes, all the time. I shoot some international musician showcases (small events for a select handful of label decision makers) from time to time in Tokyo and use 30p for the shows and interviews.
 
I use 30p allllll the time. MTV news, MSNBC docs, they all use 30p. I've been starting to use it alot more on my own stuff too.
 
crisp progressive images that are "future proof". Looks great on Interlace, looks great on Progressive monitors. its backwards compatible because it fits on the 60i stream perfectly.
 
I find it has more of a harsh-ish newsy kind of look, definately good for doc work if the subject is right. It's also great for internet video use.
