Is that this software here:

Yes, that's where I downloaded it.

Thank you, Peter.

Has somebody different sources for EX1 footage? In detail, I am interested to test if the 25 Mb/s (SP mode) footage is really compatible with HDV. Unfortunately, the link above does not contain 25 mbps footage.

That's the only source that I've seen so far. What exactly do you mean by "compatible"?

25Mbit/sec XDCAM is different to HDV as far as I know. You couldn't take that XDCAM file and print it to HDV tape without recompressing it as far as I know. Not that I can see any reason why you'd want to either.

It derives from that information in the product description:

"Selectable Bit Rates
The PMW-EX1 camcorder offers a choice of bit rates - either 35 Mb/s (HQ mode) or 25 Mb/s (SP mode) - depending on the desired picture quality and recording time. The HQ mode supports both 1920 x 1080 and 1280 x 720 resolutions. The SP mode supports 1440 x 1080 resolution at 25 Mb/s, which provides compatibility with HDV 1080i products.

Footage recorded in this SP mode can be seamlessly integrated into HDV-compatible editing systems by transferring the stream from the camcorder via the i.LINK™ (HDV™) interface. It can also be recorded on XDCAM HD's optical disc through the use of the supplied Clip Browser software."

and I am interested to learn more about what that means in detail.

The 3 files from the link above - I have also been successfull to convert them with the clip broswer, and export them to *.mxf-files. Those files can be imported in Vegas V8a without an problem, project settings must be adjusted to 1280x720 25p (one clip) and to 1920x1080 25p (the two other clips). Playback behavior on my Q6600 is fine - something about 18% processor utilization. Seems to be great material.

why mp4 can't be imported directly to v8 without converting?

"why mp4 can't be imported directly to v8 without converting? "

I presume because Vegas cannot read the mp4 container. mp4 is not a codec, it's a container which in this case contains mpeg-2 video (put simply).

Okay, so I'm catching up here and a few cigarette's short of a full pack. Are you saying that the native files put out by the Sony EX1 are NOT going to be innately compatible with Sony Vegas? That they'll have to be converted? I could have sworn I had read/heard somthing awhile back about the EX features in Vegas making this seamless?

Someone tell me it's just past my bedtime and I'm reading this all wrong.

The EX1 uses a different / new wrapper for the footage. Instead of MXF it uses mp4. The clip browser software from Sony rewraps the footage (amonst other things) into the tradition MXF XDCAM wrapper. Once that's done Vegas and FCP can handle it.
This process takes seconds. The contents are not changed or transcoded, just put in a different wrapper.
The clip browser runs under Windows or OSX but in another twist the MXF rewrap will only run under Windows.

One down side I guess I can see to this is it might double the amount of storage you need. I'd be initially kind of anal about keeping everything, just in case. So I'd probably endup keeping the camera original in it's mp4 wrapper and the MXF rewrapped copy.

ex1 is on the road.
v8.0b should read mp4 container.

Wolfgang S. wrote on 11/12/2007, 4:08 AM

do you know in some more detail, what happens during that "rewrapping"?

I understand that no re-encoding or transcoding seems to take place, neither in the videopart, nor in the audiopart - but that is my guess, I am not sure about that.

farss wrote on 11/12/2007, 4:27 AM
No bits are harmed. Apart from anything else simply the speed at which it happens is proof that nothing is happening to image or sound. XDCAMs record vision, audio and metadata such as take/no take, in/out points etc. All this is stored inside a wrapper, it was MXF (Media eXchange Format) but Sony's unique implementation of it, not the SMPTE standard. Now it's a mp4 container object but all that's happening is putting that data in a new wrapper.

Think of the container as a box, the labelling on the outside of the box tells you things about the content. The words could be written in different languages but the contents remain the same.

Bob. Been doing some CC in AE with the footage and in commotion.

Have you heard the sound recorded from an XDCAM? I imagine its the same sound system in all of them 16 Bit uncompressed linear pcm 48khz . This would be better than my marantz pmd660.

Also taking on board what you said in another post about Arri stuff being thirty years old Made me think I did some measuring and my arri matte and filter box is 80mm wide It might just fit on the lens of EX1!
farss wrote on 11/13/2007, 12:10 AM
The only difference I know of between the audio in the EX1 and it's big brothers is they have 4 channels of 16/48K. I haven't heard any recordings made with the EX1.

That matte box might be a perfect fit, unless you fit a WA adaptor.

mark2929 wrote on 11/13/2007, 2:22 AM
My plan is to use the matte box with some 85 ND filters Im sure you can set the colour temperature on the camera. Thats something else Im looking forward to control over CT. And shutter controls. I bought a wide angle lens for my XM2 and I used it about once. But Id like a follow focus though. Whats your recomendation?
farss wrote on 11/13/2007, 3:06 AM
I'mStill thinking about FF gear. Really want to wait and see what Sony and others come up with in the way of lens controllers for this camera.

Apart from that FF gear needs to be really well built, no slop or backlash. Looks simple enough but I've read a blog of some guy trying to get a 'cheap' one to market and he says it's way trickier than it looks. Other things it to ensure it has the industry standard fitting so you can add handles and whips.

The only preset colour temp is 3200K. But naturally you can white balance to other temperatures.

Serena OH thats a shame I had hoped the menu would have some presets for it! Im sure all the other XDCAMS would have.

Bob. Is the focus ring on the XDCAM likely to have standard size ring increment steps for want of a better word?
mark2929 wrote on 11/13/2007, 4:41 AM
Serena. On page 89 of the manual its showing two presets A and B that you can store as well as an adjustable preset for 3200? So I should have three presets?
