1080i/24p at midnight

[Thomas Lew]

Took some footage at midnight around campus. My favorite shot is of the car in the parking lot approaching.

Shot in 1080/24p. FCP Pro Res 422 to transcode. Didn't do anything to the footage (no color correcting or anything at all).

Very Nice!

[Bernie Hipos]

Wow! it's great in low light. I might get this one, only after selling my dvx100b.:-(

[manglerBMX]

was there any gain on this? i see a little bit of noise but it may be due to compression. but it simply looks amazing. i think i'm sold on this camera.

[tashbee]

yea looks like i will have to sell my dvx adventually and pick up one of these

[ESTEBEVERDE]

Looks like there is gain but that is not a problem for docs.

For naratives I would imagine you would light a bit.

[Coldpizza]

Looks good sharp and well handled low lights though there was a bit of stagger on the pans. Not sure if this is a compression issue or a recording one still looks very good.

[William_Robinette]

No smear.

Classy.

[ryan brown]

Whoa... that looks REALLY good. Surprisingly good. I had NO idea it would hold up that well to the low light conditions. I haven't seriously thought about this camera, but in the event business, this could come in REALLY handy.

Man oh man, now I have to consider picking up a couple of these, and I really can't afford it at the moment. Thanks a lot Thomas:zombie_smiley:

1080i/24p

I don't want to nit-pick, but you can't be interlaced and progressive at the same time. I assume that you meant to say, "1080/24p" or you could say, "1080p/24".

It would be interesting to know the gain setting and the shutter speed.

Very interesting... and impressive.

honestly I thought everything 1080 always had an i after it..... (dang I'm stupid). What does the 1080 mean in 1080/24p?

[KyleProhaska]

the 1080 means its 1080HD...1080 pixels high...so your saying its 1080p (p for progressive) and 24fps....so 1080/24p.

[TheMusician]

In high definition, 1080 is the number of pixels recorded in the vertical direction. High definition comes in two flavors of resolution - 1280x720, and 1920x1080. So something recorded in 1920x1080 is 1920 pixels wide by 1080 pixels high, but everybody calls it 1080 for short. The "i" and "p" stand for "interlaced" and "progressive". Each frame of interlaced footage is recorded in two separte fields, one field composed of all the odd rows of pixels and the other composed of all the even rows of pixels, that are interlaced to create an image. Progressive footage is captured frame by frame like a series of stills shown one right after the other. So:

1080/24p = 1920x1080 footage collected at 24 frames per second in a progressive format

720/30p = 1280x720 footage collected at 30 frames per second in a progressive format

etc.



Hope that helps a little.

geeze, it handles low light well!

[Daygola814]

Wow... that's some beautiful footage right there. I was dismissing this cam (not 100%) because of the AVCHD codec, but I think this has changed my mind. I'd still like to get the 170 though, but this footage rocks!

[reem12]

Think I'm sold, now if someone can just tell me how this compares to the amazing canon a1 in terms of codec, sharpness, and tweakabilty, and last but not least, overall resolution?

[BobDiaz]

Hi Thomas,

Several have answered, but let me say a bit more...

In some modes there are 2 different ways to scan the image; interlaced and progressive.

With Progressive all the rows or scan lines are covered in a single pass. 1,2,3,4,5, ...

With Interlaced, first all the odd numbered lines are covered: 1,3,5,7,9, ... On the second pass, all the odd scan lines are covered: 2, 4, 6, 8, 10, ... On a 60i system, each pass is 1/60 of a second. So, from the first pass to the second pass, things have moved 1/60 of a second forward. Now, if nothing moves, the image comes together normal, BUT if things move, every other line is offset a bit when the 2 passes or fields are put together.

In the photo above, the bike rider has moved from the first pass (field) to the second field. Look closely at the tires.

http://i46.photobucket.com/albums/f103/KQ6WQ/Interlaced_2.png
This is the same image but with a 2x zoom to make the scan lines stand out even more.

IMHO Interlaced video sucks big time. Both slow motion and freeze frames suffer badly by using interlaced video. With static objects, people see the 1080i resolution as is it were 1920x720P. When things move, the resolution is like 1920x540p.

The good news is that the HMC-150 is NOT locked into 1080i video, you can select 30p and 24p for 1080 modes. In that case, the 1080 video is shot progressive and the problem you see in the photos I've posted does not happen.

720p is ALWAYS progressive.

If you're interested, I've covered the issue of interlaced / progressive in my Podcasts: (See DTV and 1080i or720p?)

I second that! BIG TIME!

[Thomas Lew]

Kyle, The musician, and especially Bobdiaz thanks for the help =]

I had an idea of what it all was just never really understood it entirely but I do now thanks a ton.

Souldn't that be even?

[PKraft]

It should, even is correct.

[Justyn]

nice to see it handle the smear so well. Same thing with the 170. My HVX is horrible with the smear.. and not the nice bagel and cream cheese smear.


I would love to see how it cuts with HVX and 170 footage. That's the real clincher for me to see if ther'es any increase or such.... I'm already sold on not having to buy anymore P2

are you selling your hvx now? or just getting a hmc as a backup

[Justyn]

HMC as a 2nd camera. I wouldn't sell my HVX as it has been and will still be a trusted workhorse... plus with over a 1500 hours on the camera and only 4 gig P2 cards and p2store, I'm not sure if I'd get enough to even buy this cam.. lol IT also has a scratched LCD which I don't know how it ever happened... and it's a very warn cam... but manalive it functions the same as the camera did when I bought it.


I could never say that for a DV camera. If I shot a 1500 DV tapes my heads would be shot.. and in the past they were. I had to clean it constantly and would routinely run into dropouts.
In 1500 hours of footage never had a drop out.. so ya got to love that.


Thomas, you certainly are an inspiration to us all. Congrats on taking the leap. Have you also shot with bpress gamma? I love that on the HVX and leave it there most of the time. Wonder if it does the same thing to the HMC footie..

[NWP]

what's the minimum illumination on this camera in lux ? I have the hardest time finding the specs of this camera on the web.

[triplej96]

Stunning how great it looks in low light!

[USLatin]

I can't believe this camera... it is like it has the same chip as the 170/200a only with higher compression

[Barry_Green]

It does have the same chips as the 170/200A. Same lens as the 170. The major difference is no variable frame rates and a different recording system (and several other differences, like no standard-def recording, no interval mode, etc...)
