Best way to go on HDMI capture

[Luis Ignacio]

Hello people from dvinfo! I´m building a new machine to work with HDV sony Z1 and M25U(HDMI) or M15U deck. My machine it will falow the videoguys.com specs for dual xeon dual core. But i´m wondering it will be the best way to go.

1º Adobe prodution CS3 with matrox RTX.2(realtime premiere) and intesity pro(HDMI)??? it is possible to use both? Someone here already tried?

2º Avid xpress pro with avid toolbox with mojo SDi and convert design box to conect the M25U HDMI output with the SDI in of the mojo

I usually prefer the adobe solution because i´m already trained for, but for professional issues is best to learn another apliccation. Waiting for some directions, thanx
Luis

no ideas about it?

Why not fire wire? There is no benefit in using HDMI, unless you want to to forfeit desk control.

i tought tha i could get better unconpresed signal with HDMI over firewire

[Harm Millaard]

Once your material is on tape, there is no way to get an uncompressed signal. Once compressed it remains compressed. Using HDMI is no different than using fire wire, just a means for digital transfer, but fire wire has the advantage of transferring time code and recording data and deck control, all of which are not available when using HDMI.

Thanx Harm! so it would be good to use HDMI for live capture from the camera, right? If i use Focus FS4HD with firewire or something like that i would be getting a better image?? than getting from tape, right?

Impossible. Look here: http://dvinfo.net/conf/showthread.php?t=96213

Thanx for the directions, i will go with avid pro and m15U !and for the HDMI projects... i love experimental eltronic tests!

I thought the HDMI carried the audio & data all in one cable and as new to HD editing was going to get a new high end graphics card with HDMI to capture instead of dedicated video card ? . Then I could do others things. I've only got P4 2.8 System & Piannacle sofware is very slow at rendering. Got a couple of bits for my new build ie 150gig raptor ,new case etc..was going to get 500gig Samsung for video files , But some one said should stick with raptors even though less storage. & quad core not way to go as less than 3ghz ? Pinnacle does not support 64 bit. So may have to learn new editing software that does.
Any ideas as I've gone off the rails with which wat to go. I have a lot of dv footage to edit & now HD. I've had terrible problems with Pinnacle -but it has been easy & ok when its worked. do not like there infernal key system while upgrades give very little extra.

Instead of getting a high end graphics card with HDMI, just use on board fire wire to capture and use the amount not spent on getting a better CPU, more RAM, more disks and a good editor like Vegas or Premiere. Try to sell the Pinnacle of frustration and disillusion.

I JUST ordered an intensity card and HDMI cable, thinking there was a HUGE benefit to capturing via HDMI over Firewire. Based on this thread, it sounds like I should cancel! Opinions welcome. I think I still have time...

Hi,

Using HDMI is different from using firewire. HDMI is a digital video signal while firewire is data transfer. This means that you can take the HDMI signal out from your camera and capture it into a more manageable codec for editing.

[Joe Rogers]

So from the above HDMI is better ?. Does this mean the codec compression is less and you lose quality OR NOT .

[Harm Millaard]

I honestly can not see any advantage in a video transfer over a data transfer, nor can I see the advantage of throwing out time code data, date and time stamp, exposure data etc. and losing deck control.

I much prefer using Cineform or similar plug-ins to convert from native HDV to an intermediate codec and keeping all relevant data intact.

The advantage of the video transfer is that you can attach the camera to a TV for watching. For editing there are only disadvantages.

Thanks Harm. I was getting hung up on getting HDMI ports on computer/ laptop when my Canon HV20 has both firewire & HDMI. So its more conveinience in USING hdmi connecting to HD LCD. I think partly the problem is people hearing about the 1.3 HDMI standard where most LCD TV's are obsolete and think HDMI is superceding Firewire.
