AG-HPX170 - Is It Real

What he was trying to do was poke fun at a noob. Unfortunately sarcasm is hard to convey via internet posts. :)

I know that the HVX shoots 1080p, but it records interlaced. I've read the manual, and Barry's book numerous times.

What I was asking is does the new HPX capture 1080p/24p or 1080i/24p?

because the HVX captures 1080i/24p (amongst others) and won't record 1080p/24p

That was my only question.

I know what you mean and of course I knew it also before ;) - you got me right!

The point is, that there is "record" and "CCD-scan" and so on....

You'd have to define, what you mean by "shoots" and "records"...

As far as I understand:

The CHIPS are progressive...

The SCAN is interlaced...

The RECORD at the end on your card is progressive....


So it's not only 1080p25 over 50i, but "p" over "i" over "p" - it starts progressively and ends progressively, but in the middle it is interlaced.

So what is for sure: 1080p from HVX / HVX200A is NOT 1080p50 NOR is it natively progressive from the beginning to the end NOR is it FullHD at any time.

I hope someone will correct me if I said something wrong, but that's what I think it is: "p" over "i" over "p".
 
No, the scan is progressive. The recording in 1080 and 480 (and 576) is interlaced. The progressive modes -- 30p and 24p (and 25p, as you point out) -- are recorded in an interlaced stream with pulldown. It's the same scheme as the DVX.
 
I think you can pretty much consider the "i" stage as nothing more than storage. It disassembles the progessive frame into interlaced halves then later reassembles it as it was. It would seem this eliminates any effect that the i-stage has on the look of a frame. In effect it's progressive, period.

Or so it seems to me...
 
There we go again....

Isnt' the content on my card (PAL) 25p ? - I mean: 25 "full" frames? - Is it 50 interlaced frames on the P2 card at the very end instead?

I was supposing, that it's 25 (24) "constructed" progressive frames that were made of 50 interlaced frames that have been scanned progressively, but only every second row a time...
 
In 720, it's progressive all the way -- scanning and recording. Interlaced doesn't enter into it at all.

In 1080 and 480 and 576, it's scanned as progressive and recorded in an interlaced stream.

That's what I thought too and what I would call the "record" on the P2 card: "progressive content"...

By "record" I DON'T mean the process of recording, but the RESULT - that might be the point of our trouble...

The RESULT is progressive and the recording process is interlaced - that's why I say that it's "i" in the middle and "p" in the beginning and in the ending...
 
It's interlaced as stored on the card (in all modes but 720). But it's also coded so that the progressive frames can easily be retrieved in an NLE. It's in the NLE where the progressive footage is restored, not in the camera.

Now THIS is completely new to me and very interesting!

So a question related to this subject: WHEN does the spatial offset happen?

- between two frames?
- is it actually 3 chip-scans within 1 frame?
- so is the final frame made out of 3 individual frames with 3 positions (1. position A, 2. horizont shift, 3. vertical shift)

The HVX microsite on internet only explains the result of spatial offset... I never read how it actually works, step by step...
 
It happens at the scanning stage (more or less). Doesn't have anything to do with whether it's progressive or interlaced.

But it's a mechanical shift of the chips - no? - So it must happen within milliseconds... and with the precision of half a pixel....

Is it the chips that do the shift or a grid that shifts over the chips? - Must be like a vibration as it's so incredibly fast...

(now it's ME the noob.... ;) )
 
ok...... so then it means that red is offset regarding to green and blue and vice-versa... ?
 
Red and blue are co-sited in relation to each other. The green chip is offset 1/2 pixel horizontally and also 1/2 pixel vertically.
