PMX-EX1 for broadcast
on Apr 24, 2008 at 12:24:04 pm

Hi,

I hope this already has not been covered and I just can't find the thread.

Wondering who is capturing on the PMX-EX1 and then delivering on HDCAM for Broadcast in the US?


After Real Screen this Jan, a lot of the broadcasters stated that they were really picky about capture format for HD.

We have been shooting on the HVX200 for broadcast and QC has been fine, but we would like to explore PMX-EX1 for our next show.

Of course since we don't have a deal and we are selling our show afterward, cooperation from programmers as far as format is difficult!

Any thoughts on this?

CNN is using them on their Election Express truck for election coverage.

This camera is only one of two (as of now) that has full-raster 1920X1080 imagers; the other is the HPX-3000 (not counting the high-end cine cameras). The PDW-700 will have them, too, but it only records in 1080i or 720p.

I'm planning on getting one, soon.

I would think it would be decided on a case by case basic for each broadcaster. However at 35 mbit and full raster 1920x1080 I'd imagine the average broadcaster would have a tough time turning their noses up at EX1 footage with everything else that makes it under the wire these days.

Translation for those of us outside of Discovery's production circle?

Yes-please what is silver level at Discovery?

As well, our show will probably end up on Speed Channel. They were good with the HVX200 but now are mum about the PMX-EX1.


The other producer on this is worried that the PMX-EX1 or any other XD cam for that matter won't meet QC at Speed since the format it is 35mb vs the 100mb you find in the Panasonic P2 line.

It means you can make a whole show using the camera with no restrictions! Something you can't (officially) do with the HVX

It's not a completely fair comparison to say that because one format is 100 Mbit and another is 35 Mbit that the 35 must somehow be 65 Mbits lower quality. XDCAM EX is variable bitrate MPEG-2 meaning the amount of Mbit data spent per frame fluctuates based on the complexity of the scene- always being optimized for highest quality. DVCPROHD is constant bitrate meaning every frame receives the same amount of data irrespective of imagery.

What that means in laymen's terms is that XDCAM EX at 35Mbit is every bit as capable of capturing the same level of ultimate detail and color and DVCPROHD at 100 Mbit. Panasonic realized this goal themselves with their more efficient AVCIntra codec in a way. So I suspect the Ex1 especially with the full 1920x1080 resolution will eventually pass muster.

Sorry- I meant to say its that EX as a long-GOP format is closer to the AVCHD format rather than AVC-Intra which is true I-frame. DVCPROHD and XDCAM EX are indeed quite different codecs and of course as with anything else are not going to be equal in all shooting scenarios. Each broadcaster will evaluate the EX1 and its suitability for broadcast as it comes up.

Hi Noah

I just posted this as a new thread but I would like to get your feedback especially. Thanks...

Hi

I recently tested the Ex1 to the Sony HVR Z7 to the Panasonic HVX201AE and found some very interesting problems regarding the EX1. We shot all kinds of scenes incl. Indoors, Outdoors, Sunset, Dusk all in 25p...and watched all the results on a Baselight System projected in 2k on a big cinema screen. The tests were done for an upcoming cinema documentary.

At first we all loved the EX1 for sharpness, latitude, color rendition and especially for its low-light capabilities. But all this love went away when we looked at shots were the camera moved. On slow pans across f.e. a green grass in the foreground and a city in the background the image suddenly went totally blury. At first we thought the camera was out of focus but as soon as the camera stopped the stellar sharpness was back. On the next telephoto pan across the city skyline all detail was lost as long as the camera moved. It was just a big blur. But it wasn't motion blurr due to the 25p it was a compression issue. On a shot watching cars drive through the frame the cars looked like ghost images. Totally unsharp but when I started panning with the cars the were totally sharp again. What was the worst though was panning across a field of grass. All detail was gone as long as the camera moved and it was back when the camera stopped. But the killer was when shooting handheld on a second day of tests. The person was walking and as log as he moved with the camera everyting wa fine but as soon as the camera would move out of sync with the person he went blurry.Again it did not look like motion blur. When looking at it in single frames we noticed that only every 8th frame was totally sharp everything else was blurred. We compared all this to identical shots with a Sony HVR Z7 on HDV and the problem was negligible. You could see some motion blurs but nothing that would feel unnatural. The images on the Z7 remained sharp throughout much of the shots even though both cameras use LongGop encoding. When contemplating about this problems my conclusion is that the EX1 due to its higher resolution also has a stronger compression. When the camera starts moving the compression suddenly kicks in and makes it highly visible. Even minor, very slow movements cause this problem. We watched the footage on a 25foot screen which made it highly visible but even on a 42" Plasma a home it was very noticeable. I am deeply disappointed about this as this LongGop Issue makes the EX1 unusable for big screen projects. The HDV performed much better even though it didn't have the latitude. But compared on a splitscreen with the EX1 it seems to be the better choice.

Has anybody seen this problem or any thoughts about it? I would have preferred the EX1 because it also offer 60p slowmo and is very good in low light. But I can't live with these blurr issues unless some solution is found.

Best wishes

I had a friend who had the same problem. You need to turn the detail completely off on the EX1 and this issue should go away.

Good Luck,

Paul
