EX1, MBP and MXO2 Questions, Such as DVCPro and ProRes Capture
 

Anyone out there using the MXO2 with this setup at all? I'm very curious. I've seen some say that you can capture Prores 422 with a MCP (I have a 2.6 + 4GB RAM) just not HQ. I've heard other accounts that you cannot. What about XDCAM 50 with the new 4:2:2? And lastly, what are people's thoughts on capture into DVCPro HD as opposed to XDCAM with the MXO2?

I have a big shoot in a week and I'm seriously considering the MXO2 versus a mini converter because of the added value. I guess my biggest question though, is it worth it if I am just running a MBP? I edit with a SATA RAID setup at home with it so it would obviously have an impact on how I approach workflow a bit.

MXO2 is an excellent device. I have been using it since before I could even admit I was using it.

You cannot capture real time in ProRes on a MacBook Pro. Real time ProRes capture requires a quad-core chip minimum. Anyone who told you that does not know the product. You can capture DVCPRO HD. I presume you are asking this because it is your intent to go SDI from the camera directly into the MXO2 and then into computer for obtaining 10-bit 4:2:2 footage.

If you have already recorded to cards, might as well work with file based footage since once the footage has been written to SxS, it is already compressed. Playing it out of SDI will not give you uncompressed 4:2:2.

Thanks Ned, what I was looking at it for was for on set acquisition. Can you tell me a little more about how you're using it in your workflow? Have you captured full DVCPro HD off of it and what are your thoughts of it? The project I'll be shooting needs to have plenty of room to work with the color in post so the more I can get out of my EX1 on this one, the better off I'll be.

I've captured DVCPRO HD from it going SDI from Camera to MXO2 to FCP using capture now, uncontrollable device. An external FW800 drive should be fine for capturing DVCPRO HD.

You really have no reasonable option with the MXO2 and a MBPro other than DVCPRO HD. I do not think its resolution is as good as ProRes but you will certainly have more latitude with color than 4:2:0 footage, although I must say that XDCAM codec footage holds up amazingly well.

The IoHD does a real time transcode to ProRes 422 (both standard and HQ) but it is $3K more than the MXO2.

But in the final analysis, the uncompressed footage from the EX is gorgeous and I don't think you will be disappointed with DVCPRO HD.

But, before committing yourself to this, test it first. Capture in DVCPRO HD on your MBPro. Connect the MXO2 to your MacPro (you know you get both interfaces) and capture both ProRes and uncompressed 10-bit, presuming your raid can handle it. Work with the footage and export a sample in your desired delivery medium. See how it looks.

MXO 2 live acquisition
 

I have a similar need coming up, a four camera shoot switched through a sony anycast. I want to use the hdsdi slots, (record sxs in camera) and record the live HDSDI switched feed. I also need to record 16x9 sd. The composite output from the switcher will run to the client projector in another room, and
Will the matrox allow me to record hdsdi as quicktime hd or dvcprohd on a macbook pro, as well as a standard def output to a dv deck? In other words, two live outputs - firewire and sd.
Or maybe two firewire outs - one HD to the macbook and one SD i link to a deck?

First of all, the MXO2 does not have firewire out nor does the IoHD, in fact. I also do not believe you can stream both HD and SD downrez simultaneously from the MXO2. I'll double-check this, though, a bit later. IoHD would allow simultaneous HD and SD but you would need component or SDI deck. Its only firewire connection is the FW800 to the computer.

Ned

Upon further research, I can determine that the SDI and component outputs of MXO2 are independent. That would allow you to output HD on the SDI and SD on the component outs.

Ned

sounds like this will work
 

Thanks Ned, it sounds like I can run the HDSDI out of the switcher to the mxo2, then into the macbook to record dvcpro HD, and run the SD component out to a deck.
I'll have a chance to try it our Wednesday, thanks for the information

I actually just talked to Matrox and they confirmed that one for you Denis. Said with a MBP you can capture SD Prores HQ, DVCPro HD but that is about it. FCP is unable to capture XDCAM since its MP4.

You don't capture XDCAM; you ingest it and FCP rewraps as a .mov QT file in XDCAM codec.

The whole purpose of going SDI out of the EX cameras is in live shots to obtain uncompressed 4:2:2 footage in whatever codec your machine/storage can handle OR to use with the Convergent-Design boxes to capture MPEG 4:2:2.

Lattitude is governed by the camera front end and not the codec, unless it is a particularly bad implementation of the codec. Given that the heavily subsampled 4:2:2 (1280x1080) of DVCPRO HD only has 30% more chroma information and 50% less luminance information than the Mpeg2 from an EX there really isn't that much difference. On a big, full resolution monitor the DVCPRO HD will look soft compared to the same shot done with an EX.
