Editors opinion – Panasonic HPX-300 v. Sony EX3 footage
-
Rafael,
Thanks again for your insights. Yes, I do understand the deal between the different size captors and how important they are(my experiences with my Canon 7D have been fantastic and I know it’s the imager size and the lens.) My question would be then why has someone like Walter seen a lot of compression artifacts from the Sony EX 3’s and not that much from the Panasonic hpx-300? When I tested a EX3 and shot a tree, the static shot was fine until the leaves started to move in the wind I saw compression artifacts (again shot on a EX3 with stock lens, shooting to the SxS cards with a scene file I find on the XDCAM / EX forum from Michael Palmer) I did not see this type of compression artifact with the Panasonic until I went to 1080p in low light.
Have you seen any compression artifacts while shooting? Again, shooting straight to card and not your NanoFalsh.
How does your footage hold up in post with use of FX’s, color correcting, grading, rendering, transcoding, etc… Where does your footage finally end up? Where is it seen, web, mobile device, DVD, BlueRay, Broadcast?
Thanks again for your insight, and remember, tigers don’t like pepper, they like cinnamon.PHIL YUNKER

[Phil Yunker] “My question would be then why has someone like Walter seen a lot of compression artifacts from the Sony EX 3’s and not that much from the Panasonic hpx-300?”
That’s easy. The compression scheme. Long GOP 25 to 50mbps MPEG-2 compression vs. AVC-Intra or DVCPro HD at 100mbps.
If you are recording to the camera’s internal disc recording mechanism, then the camera itself is almost irrelevant. A good quality HD camera can produce excellent 1080 and 720 picture.
Now tt all comes down to the quality of the codec. In this regard, more data, more information to the card / disc. 100mbps vs. 50mbps. Twice the information and a better compression scheme in DVCPro HD and especially AVC-Intra.
In case you never saw it, here’s an article from last year by Jeremy Garchow when he tested out AVC Intra using the HPX-2000 camera.

So what Rafael is saying about imager / captor size is irrelevant, at least with these two cameras or this discussion. It’s all about the CODEC and you are a true believer in the AVC-INTRA codec and even the tried, true and proven DVCPRO HD/100 CODEC. My biggest concern with the Sony EX3 is the compression artifacts that I have seen and have heard about (shooting to the SxS card) not to mention the funky design of the EX3 which would require an additional purchase of some type of shoulder mount.
Well, I’ve been researching for a while and still uncertain, yet I’m leaning towards Panasonic due to my experience with other cameras. Also, the NAB show is what two and half months away, maybe I can hold out a little longer to see what pops up there.PHIL

Phil,
I just deleted a long answer with some considerations about the EX-1 vs the PANA300.
I just find out that the PANA costs some 10K. I was considering it as an option because I thought that was some 7K.
Now I can tell you without any hesitation: If you can not buy the PANA500, run and buy an EX(1/3/1r) and the NANO. The PANA300 is just another intentioned mistake.
Cheers,
rafael
PS: SONY and PANA are really mean. They release their best achievements just in function of what the competence offers. The best example is that the EX cameras could be recording 422 at much higher data-rate just with a Firmware update. Already records 87Mbps when overcranking. -
Hi Phil,
You have to try the DPX file created from P2 CMS conversion plugin and put it into the Apple Color, or other grading system and you will see the real beast that hidden in the 10bit AVC-Intra 100 codec 😀
