XDCAM EX Codec

I tracked down some more info about the codec used for the new Sony XDCAM PMW-EX1 camcorder. As you can see from the table above, there are two general recording codecs. The HQ model has a higher maximum bit rate that is variable and also includes different resolutions--either 1920x1080 or 1280x720. The SP mode is basically the same codec as HDV 1080 line variation that Sony uses in the Z1 and V1. It is a constant bit-rate at 25mb/s at a resolution of 1440x1080. The advantage of working in this mode is that the signal is compatible with gear that knows HDV, like FCP or an HDV deck. So that while shooting, you could record to a Sony HDV deck or you could record with capture now in FCP through firewire out on the camera.

Interestingly, the SP mode has the same limitations on variable frame rate as other Sony camcorders, like the V1. That is, you can record 24p (or really 23.98p) but it it recorded with pulldown into a regular 60i (29.97interlaced) signal. So to edit that in native 24 fps, you need to remove the pulldown, which is tricky to do (especially so if you want to keep your timecode.) It looks like the HQ mode handles real variable frame-rate, recording the signal in the frame-rate that you set and not trying to squeeze (or stretch) it into 30 interlaced fps. All XDCAM EX media files have a MP4 (MPEG-4) wrapper.

No DV or DVCam recording. The bad thing about that is that you could have squeezed a lot more video on the expensive SxS cards with support for standard definition recording. Prices are around $500 for 8GB and $900 for 16GB now. With 16GB of memory you get as little as 50 min. in HQ mode, and exactly 70 min. in SP mode.

We are still waiting for a direct interface for importing from the memory cards into FCP. I'm not sure if there is any support right now for the files on the memory card and FCP yet, but hopefully Apple is working on getting a good solution soon.

Here's a direct quote from the rather large PDF that I got this info from:

The SP mode supports 1440 x 1080 resolution at 25 Mb/s,
which provides compatibility with HDV 1080i products.
Footage recorded in the SP mode can be seamlessly
integrated into HDV-compatible editing systems by
connecting the camcorder via the i.LINKTM* (HDV)
interface. It can also be recorded on XDCAM HD's optical
disc through the use of the supplied Clip Browser software.

New Sony Memory Card Prosumer Camera

Sony looks like it has a great new camera on its hands for the prosumer market. The PMW-EX1 records to solid state memory--a new format called SxS Pro. Unlike P2, it looks like there will be multiple manufacturers, which means lower prices in the long run. The EX1 should be selling in November for around $7,500 with two 8GB memory cards included.

For editors, very confusing what this means right now. The recording format is based on the XDCAM format, which is recorded on blu-ray optical discs. But EX1 tweaks the formats--different file wrappper and the option for higher resolution, a full 1920x1080. The new XDCAM EX format is not fully supported by Final Cut, but there might be some native support if you shoot in the right way with this camera--not sure. Also the camera has a firewire port on it that says HDV. The camera doesn't record in HDV but can it transcode? Lots of questions.

This camera looks like a giant step up from the Z1 in just about every way. If you want the low-down there are already a few articles on the web from folks who have been testing pre-production models. Here's a good overview from FreshDV of what info is out there about the EX1. Here are two in-depth articles, one from Nigel Cooper and another from Simon Wyndham. There are so many interesting new features on this camera, it's worth getting a broad overview.

I'm still not sold on the tapeless workflow, but this looks a great camera. I'm just worried about backup for this footage. Sony offers a unit that transfers from the SxS Pro cards to Sony's XDCAM discs (with some drawbacks as Simon Wyndham points out.) Otherwise, it's archive like you do computer data--either optical disc burning or stacking up hard drives on your shelf.

Sony Announces sub-10K Tapeless Camcorder

Was it 3 years ago that Sony and Panasonic offered their divergent views on tapeless workflow? Sony touted the Blu-ray optical disc as cheap storage with high-capacity, but offered more expensive cameras. Panasonic's P2 cards were solid-state memory, which allowed a smaller-form factor and cheaper cameras, like the HVX200. But those P2 cards are still pricey, despite plummeting costs for flash memory.

Well, Panasonic isn't wavering from its commitment to P2 with a bunch of new high-end gear, like the AJ-HPX3000 and AJ-HPX500, and the low-end HVX200 is still popular. But Sony is trying out flash memory with a new camera, the XDCAM EX

This is a sub-$8,0000 camera that records onto a new type of flash memory called SxS. Sony will sell SxS, and SanDisk will also sell cards for the camera. It records in a lot of formats 1080 at 60i, 50i, and 24p, and 720 at 60p and 50p, as well as standard-def. The XCAM EX records with the MPEG-2 codec, but I'm not sure what kind of bit-rates. They mention 18mb/s, which is equivalent to HDV. So no indication yet that the quality will be an improvement on the HDV format (one nice thing about the HVX-200 is that it offers DVCProHD, which is a better codec than HDV.) Like the P2, you can get an overcrank effect for good slo-mos.

The XDCAM EX should come out in the fall. The SxS standard was just announced too. So no word on storage pricing. I'm guessing it will start high, like the P2 cards, but I'm hoping it will fall fast with flash giant SanDisk also manufacturing SxS cards.
