SONY HDR-AX2000E: "only" 1080i via HDMI, not 1080p?

[flashandpan007]

Hi,
I wanna buy a semi-pro camcorder and thought of getting a Sony HDR-AX2000E. But is it bad that the Sony HDR-AX2000E outputs only 1080i over HDMI? Even a Sony HDR-CX700VE should be able to output 1080p over HDMI (but has Mini-HDMI at a bad position).

But you can store AVCHD-Files in 1920x1080p25 with 24MBit/s (I heard: in non interlaced container! [can be read in manual] -> true native progressive 1080p). That's what I need!!

A Canon XF 100 could also be a option, but it's not a 3CMOS (I personally would prefer CCD, but this is another topic ...). But I don't know if it has true native 1920x1080p25 if selected.

BTW: I noticed that the AX2000 has the regular size HDMI port at a good position for plugging in a long HDMI cable for viewing a LIVE-Motion Picture with a FULL-HD beamer. How long can be a HDMI cable (recommended)?


What do you think


Thanks

The AVCHD standard up until recently only supported interlace video at 1080 lines. There is no current AVCHD camera that I know of that will internally deinterlace convert 1080i to 1080p for HDMI output. All output 1080i. Also capture devices like the Black Magic Intensity only accept 1080i (not 1080p).

It is the job of the monitor to deinterlace 1080 50i for display as 1080 50p or 100p.

Recently the AVCHD standard was updated to allow 1920x1080 60/50p, 1280x720 60/50p and MVC 3D. The new standard is called AVCHD Version 2.0. Beware of proprietary AVCHD 1080p equipment that doesn't use the new version 2 logos (e.g. Sanyo uses a mp4 container, not standard m2ts transport stream).

Alternate 1920x1080 50p formats are Sony's XDCAM-EX, Panasonic's AVC-Intra and certain JVC MPeg2 models.

HDMI like DVI needs extra shielding for lengths longer than 5m. HDMI v1.4 runs at higher bit rates so is more demanding. Details in these links.

For long lengths out to 100M it is best to use an HDMI to SDI converter. For longer than that, Black Magic has a solution.

But I found on page 88 in this manual
http://www.docs.sony.com/release/HDRCX550V_handbook.pdf
"HDMI RESOLUTION
Select the output image resolution when connecting your camcorder to a TV with an HDMI cable (sold separately).
HD CONTENTS
Set the output image resolution recorded with high definition image quality (HD).
AUTO Normal setting (outputs the signal according to the TV automatically).
1080p Outputs the 1080p signal.
1080i Outputs the 1080i signal.
720p Outputs the 720p signal.
480p Outputs the 480p signal."

I'm going to buy the ax2000 because that cam is exactly that what I want and need

So I think because of your statement, that the 1080p is deinterlaced internal in the cam xr 550, right?

[edDV]

If the xr550 output works in 1080p mode, it would need to deinterlace in the camcorder. Expect better performance if the HDTV/monitor does the deinterlace.


HDR-AX2000E manual
P24 shows recording formats.
P70 shows HDMI output settings There is no 1080p setting. Only 720p, 1080i and "auto".

As said above, the TV/monitor will do the deinterlace.

Note that computer type monitors normally don't accept interlace (1080i/576i). 720p should work.

Because I have read the manual already, I asked in this forum about 1080i, but thanks for that

I have two MonitorTV from LG:
LG M2362D
LG M2762D
HDMI: both can read all needed resolutions in interlaced and progressive (480p/576p, 720p, 1080i, 1080p(24Hz/30Hz/50Hz/60 Hz)), but thanks for the advice. I didn't know that regular pc monitors don't support 1080i.

Thanks

I didn't know that regular pc monitors don't support 1080i.

They don't take 576i or 480i either.

I think flashandpan007 and edDV are talking about two different things. edDV is talking about 50p. flashandpan007 is talking about 25p.

25p-in-50i and real 25p are nearly equivalent in most uses, but there are some gotchas. It doesn't need "deinterlacing" - you just treat the frames as frames - job done.

Can't help with the actual question though - sorry. I can't find a definitive on-line list of what formats HDMI supports. It's probably device dependent. Hence using 50i gives best compatibility?

David.
