Hi,

Im looking to invest roughly $1200 on a grading monitor.

Could someone with good knowledge with monitors put me on the right direction?

I'm thinking a second hand 2009 hp dreamcolor which has been really popular in the past or a new eizo sx2462W.

What would people recommend?

Thanks

Hi,

I will be shooting a video in the coming weeks. This is the kind of look I'm going for:

I'm not very experienced with lighting and i'm trying to get the hang of it.

What kind of lights would you recommend?

Thanks

Hi,

I'm buying my first teleprompter. I will be using to make low budget profile videos and so forth.

I'm choosing between the one take teleprompter and teleprompter people.

Any advice or experiences with these prompters would be much appreciated.

Thanks

Awesome! thanks for the explanation.

So GoP is just one method of compression. There are also others like MPEG-1, MPEG-2, h.264 etc.

Is iframe uncompressed and all full images?

What do dslrs like 7d and 5d use?

And what do higher end cameras like reds and arris use?

I'd love to know.

Thanks!

Think of it like this; in an iFrame codec, each frame is a still image. in a GoP codec, the 1st frame is a full image, then the subsequent frames (for however many they wish to set it) just records the differences-- these frames are later reconstructed from this data.

So, imagine a white wall. With an iFrame codec, and a static shot, you'd wind up with, let's say, 15 frames of white wall, each one a full photo. In a GoP codec, you'd have 1 full frame image and then (assuming nothing changes @ all... hypothetical, of course) 14 frames of nothing! Later on, in the editing suite a computer would "reconstruct" that missing data by adding the changes (in this case nothing) to the original fame to make up the information.

 

Hope that makes sense.

ahhh, ok its starting to click. I understood your explaination. So thats why low GOP is good. Because each frame has more of its own independent data instead of a set up frames which just record the changes.

Is this just so each frame has less info and really just records the changes from previous frame instead of a whole new frame therefore its being compressed?

Does it just make a difference in editing or can you see the difference as well?

Okay, i think i may be getting it. So lets say you have 24fps. Each of those 24 frames have their own number of frames with in them which hold a certain detail?

Or

From 24 frames, a certain number of them are combined to compress the data? Kind of like interlacing?

Thanks for the reads. I read them. So I may be getting it.

Hi,

I've been trying to understand what GOP is.

Everything I read is too complicated.

Maybe if someone could dumb it down I'll start to understand it.

Thanks

I guess you just put a piece of clothing over the vest?

cool:) thanks

Easy. Check out the Snorricam rig at Duall.

and seeing it in action.

 

Oh cool, so its just a steadicam facing yourself? I love that effect. How do you hide the body suit? and how do you stop the arm from moving around. is there a way to lock it?

Theres a effect I really like but not sure how to achieve it. When the subject is moving it feels like the camera is attached to their body facing them and moves with them.

In the chorus of this song they've used this effect.

This song also uses it. Like you can see at 2:22secs

I'd love to know what its called and how it is achieved:)

Thanks

Nice

Given that fact that the entire camera unit on a Iphone 4s is smaller than a human finger nail and far smaller than just the sensor inside a 5D i am shocked at the how close the images are.

With a fast apature lens it can also get a good shallow depth of field. Like in this video

How can it get such good footage when the camera unit is so small? The sensor must be tiny.

Will it be bad for videographers if everyone has easy access to great quality cameras? Will it reduce the value of our work?

Secam at its basic level was always very similar to PAL and as a result doesn't really exist in the digital world. Places that used secam generally migrate to PAL digital. There are no secam DVD discs for example! Secam is a bit meaningless in the digital world as it is the same resolution and frame rate as PAL normally. So secam IS an analogue thing.

 

Digital broadcast can be both HD and SD. Here in the UK standard definition digital terrestrial broadcasts have been around for a little over 10 years, whereas HD DTT broadcasts are a very recent thing here.

 

What you will find is that basically, digital tv channels will broadcast in 1 format only. So for instance, if it is a high definition channel, it will broadcast 720p or 1080i only. It won't broadcast 720p one moment, 1080i another and PAL at another instant. If it is a 720p channel, all formats will need to be converted to 720p for broadcast. If it is a 1080i channel, then all formats will need to be converted to that format for broadcast. TV channels don't switch around resolutions. In fact that kind of thing is known to upset set-top boxes here in the UK.

 

Hope that makes things clearer.

 

love

Thanks for your replies everyone. It makes sense now:)

NO SD Tevevision can be PAL, NTSC & Secam.

 

HD is neither Pal no NTSC

 

No it's always been answered.

ok cool, and by HD=digital and SD=analogue?

It can't because the whole standard definition broadcast system including receivers are set up for PAL and haven't been changed. You may be able to play region 1 DVDs in PAL countries (if your player is chipped), but that's not the same as broadcasting NTSC.

 

HD isn't PAL or NTSC, but PAL countries still use the same 25 fps frame rates, they don't broadcast the NTSC frame rates. Their next step up is 50 fps rather than 60 fps.

Just so i understand correctly PAL and NTSC apply to analogue television, and also apply to digital television. Or PAL and NTSC are only restricted to analogue television and are outdated and make no difference with digital HD and SD television. So Australian digital channels can now broadcast all formats whether rendered in PAL, NTSC or SECAM?

Yes is does, as the fps is different. I think you need to give more information so we can answer your real question.

I was just discussing with someone that australian tv uses PAL which is 25fps. But my friend suggested that doesnt matter what fps your footage is with digital tv, because PAL NTSC all work in all regions now.

So i guess my question is can Australian tv broadcast NTSC as well with the introduction on digital tv? Also, can it broadcast footages with higher frames rates? Like 60fps or even higher?

Hi,

Does PAL or NTSC make any difference for broadcasting with modern digital tv?

Thanks

Hi,

This is a very simple music video i put together for a friend of mine.

Please watch and i hope you enjoy it.

Has anyone here ever used the miller DS 10 head?

What did you think of it?

I was using an Arrow 40 head, the sticks are from the Solo Series. They make the solo with both 100mm and 75mm bowls.

Have you ever used the miller ds 10?

Miller used to make a very solid carbon fibre set of sticks to go with their bowl heads. I travelled abroad with them shooting a doco a few years ago and they were great. Much nicer to use than the manfrotto sticks.

What head did you use with those miller sticks?

Not unless you've got a bowl adapter that fits the screws. I'd buy tripod legs with a bowl, trying to level legs without a proper levelling system is just a total pain, so I'd check out good quality used legs with a bowl if it's a cost issue.

I'd recommend that too. Using a poor or makeshift tripod is a sure fire way of infuriating yourself with equally bad footage.

Thanks for your reply guys.

I asked this because I have a manfrotto 501 hdv head and cullmann legs. I love the cullman legs. They are very tough. I can also make them very tall or short but i hate the manfrotto 501 hdv head. It not a very good head. I also have a miller tripod which is incredibaly smooth but very old. It's very hard and vibrates so its not so good for dollies. It doesn't get very tall or short so i can't use it in all the shots i wish. I was hoping to buy another miller head and place it on a cullmann legs.

The old option would be to get something like the miller solo legs which would be as practical as my cullmann but they are very expansive!

Perhaps there are some good heads you could recommend that would fit on the cullmann photography legs (Which i think are targeted at video makers).

Is there any way to fit a head with a (sorry don't know the name) ball base like this...

to a tripod legs with screws?

like this...

Thanks you

Thanks for your reply. I've been trying to set it to the text or put it on autofocus and setting it to what is autofocused. I'd like to try your advice. Do you mean to set my cameras focus to infinity and then focus my view finder?

I think i understand what you mean now.

When i adjust the vf even if its off my eyes will focus on it but get tired. I tried looking far out of the vf and then into the vf and that helped.

I still would like to know if this is what you meant?

Thanks

I always wanted to get into it. I wrote my own songs and wanted to make a music video for them. Took the plunge. loved it and became serious about it.
