Yes and I would not wish that on anyone. 35mbps and MPEG-2 compression = terrible format for chroma key. It was utterly painful working on a chroma key project shot on the EX 1 and 3. They look amazing when taking the image out of the HD-SDI live, but after it’s been recorded to the card, it’s terrible.

Get one of the new Panasonic AVC-Intra codec cameras and shoot on that instead.

Or ingest the cams SDI output straight into FCP using the best codec you have available.
I fully agree with Walter. Once had to do a 30 second clip, took me an hour to get half decent results…Bouke

that doesnt sound good at all!
but what about transcoding to ProRes while capturing? would that change anything? -

And this only works live, having the FCP system on set with the camera taking the feed directly out of the HD-SDI output.
Once it’s recorded to the card, outputting via SDI or converting the XDCAM footage to something like ProRes will do no good.

any other Sony camera you could suggest?
what if we this is the only option (camera)?!!! should we just avoid the Chroma key and come up with another idea? -
Nope.
It’s the compression that will byte you.
So the only way is to ingest straight from the camera.
As Walter pointed out, perhaps i did not made it clear enough…Connect the cam to the computer and ingest while shooting, avoiding the cards.
Clear?

that is not possible for our production!!

well, get a HDcam rig and a deck 🙂
Why would it not be possible? You just have to bring a Mac with a decklink to the set…
Or, if your FG is just a small part of the composition, shoot Digibeta and composit the SD fg image in the HD bg.
Digibeta cams in the states seem to be dirt cheap nowadays.

HDCAM.

If all you have is this camera, take an FCP system to the set and capture straight out of the HD-SDI output of the camera to ProRes in your FCP system.
If that’s not possible, drop the Chroma Key altogether.
