My HPX-300 evaluation

Well-known member
I checked out the 300 again today, this time shooting in DVCPRO HD instead of intra-100. I wanted to make sure I could view the footage on my MBP back at the ranch given it's current configuration. I know AVC-intra 100 rocks, no question there. Playback was done in P2CMS.

I shot in 1080P/ 30P /Cine V, as this is what I use for the primary client that I'd be buying the camera for. The rest of my work is typically DVCPRO 50 30P. I did not shoot any footage in that mode, as I don't really have any concerns about this cams performance in that realm. Nor do I have any concerns with the different flavors of 720P.

I wanted to test the camera again because I still had outstanding concerns about skew and whether it would be within workable parameters for me and my work which is broadcast, corporate, and an aviation industry client. Within the broadcast and corporate realm, much of the work is journalistic and documentarian style wise. So... handheld work as well as sit down interviews.

I had some concerns about noise with the camera, but that had taken a back seat to the skew concerns. Therein lies the irony of my test observations today.

Skew (1080 30P)- Sure when I whipped it around , and particularly at the long end of the lens, I could get the camera to skew like a mutha- footage I'd never shoot unless I was doing an earth quake dramatization... Then again the skew could be a nice effect
:-O . Everything I shot was handheld- long lens follow shots, with a zoom out on some, and some walking wide angle shots. The last shot is a common one for my shooting- particularly at the wide end of the lens. Even partially zoomed in, it was more than acceptable. I don't know about any one else, but a pushed in walking handheld shot is not something I commonly do- unless I happen to get the once in a lifetime shot of Big Foot or Nessie hanging out with Jim Morrison... Like I said, even pushed in a bit, no problem. I'm not saying it wouldn't skew under some circumstances, but by and large it's not a problem for what I shoot and my style. I shot long lens handheld shots of cars going by ( 40mph) that I'd have no problem using whatsoever ( no noticeable skew), although typically if I'm shooting the longest lens- I'll be on sticks. Trying to hold a max zoom static shot did show some skew. It appears that the vibrations and quick/snap direction changes will induce skew, more so than a handheld shot that has smooth motion in it. Frankly, the skew is now a non issue for me.

To echo what others have suggested, the VF exaggerates skew. What looked problematic in the viewfinder was typically not so in the playback, except for the more extreme shots as mentioned above. How nice it is, to actually easily pull focus with the VF. No more zone focusing ala HVX 200/ 170.

More good stuff.

Even in DVCPRO HD ( as Barry has mentioned) the picture from this camera is a marked improvement over both my HVX-200 and 170. The footage sparkles, and it's clearly sharper and more resolved. i can't imagine the Intra-100... Game on Garth.

The ironic part.

Noise- While viewing the footage it became clear in short order that noise was a bigger concern than I initially presumed it to be. As Guiseppe has stated repeatedly ( ;-) ) the speed and degree of noise in certain tonal ranges is no small matter. I gotta agree with G. on this one, and respectfully disagree with Barry about the noise challenges with the cam. In certain tonal ranges the noise in this camera is certainly greater than my 170 in my experience. In the high lights, lighter mid tones and in the blacks- no big concern IMO. But, using the zone system as a reference, the noise is particularly pernicious in zone II and dipping into III and II on either side.

My big concern-skew, was overshadowed by the noise I saw in this particular tonal range. That was the bad news. The good news is that I did not check to see how the camera was set-up, other than that it was on -3db. Judging by the footage the master ped was not too far down the scale, and I sense that the detail coring was not really set up to have much effect. Given footage posted by others here such as Ben's "goodbadugly" test, I feel pretty assured that the noise can be reigned in. The "go cart" footage that Barry posted today really puts my mind at ease in this regard. That's beautiful stuff, and just what the doctor ordered.

Sure, i'd rather not have to tweak some of the paramters to the degree needed in order to tame the darker mid tone noise, as it reduces the adjustment range. But hey, if it accomplishes what is needed to tame the noise beast adequately, then I'm good. It's certainly not a low light wonder-cam, nor a 2/3 inch CCD, nor my first choice for shooting a film with a lot of night scenes, but for my purposes It's good if not great in many circumstances. I'll be holding onto my HPX-170 and Brevis for shallow DOF, Art, personal and cinematic stuff (among other reasons) .

It's time to wrap this novel up and hit the sack, so I'll conclude. I'm going to take the plunge, get off the fence and buy one in the next day or two. It's a bit nerve wracking to drop the coin on this camera package given the vast economic destruction that our glorious leaders ( past and present) have bestowed upon the economy. However if all goes well with the client that I'll use this camera for, I can pay it off in pretty quickly. As of now I'm throwing a lot of dinero down the rat hole in HPX 500 rentals- and I have just as hard of a time pulling focus as my HVX-200. What the ?.... why I oughtta...

This camera certainly has some caveats, but it's going to be a winner within it's limitations.

Take what you like and leave the rest. ;-)

would love to get some 1080p proress/P2 files from you to post up for others to see.
 
Nice evaluation.
Although I had a different experience with the skew I agreed with most of your comments.
I would like to add something, I'm working with some green screen footage captured on AVC-i 1080 24p by the HPX300 in good (but not ideal, low budget project) conditions and the noise is very acceptable. This time I was not part of the shooting so I can't say much about it, but it's clean and beautiful footage.
 
Thanks for the write up. As soon as I get finished editing the current project I am working on, I'll be demoing a 300 for myself from my local dealer.
 
not to hijack this tread but some other really nice footage I have is from someone who posted a P2 file on our server, this was taken from it. The footage was VERY clean other than the interlacing artifacts (it wasn't native 24 i'm guessing) but it was some of the first truly nice footage i've seen and it wasnt even anything special. I played the clip back and took a screen shot from my monitor just to show you guys. I usually hate when people post pictures instead of video, but this actually does show you great detail even from the still.

Hi,

Send me the link to that clip along with a password, I will download it and tell you exactly what it is. It is all in the metadata. It actually looks like some progressive capture, could be 30 or 24.

Thanks,

Jan

Hey Jan, I just checked the metadata and its "AVC-I_1080/29.97p" and " <FrameRate DropFrameFlag="true">29.97p</FrameRate>"

I saw something interesting in the metadata, check this out...

<SerialNo.>C8TNA0128</SerialNo.>
<ModelName>AJ-HPM110P</ModelName>


Why is the camera called the AJ-HPM110P card reader and not the camera instead ? Just curious.

I can email you the info if you still wanna check if for yourself.

Sounds like the clip was either recorded directly onto an HPM110 (via SDI) or someone used an HPM110 to trim the clip down.

This is the recorded output from a timeline, not the camera original. As people will notice from the file that they download on the Go-Karts, it too will have the P2 Mobile as the recording device. See the FCP cannot output an AVC-Intra native file to the P2 card. So Kona Card out 10 bit from the ProRes Timeline to AVC-Inta recording. Done. We are looking at the edited recording. and see that 29.97P, it was a progressive capture. and the output was progressive recording. It is one of the cool things the P2 Mobile can do that the P2 Portable cannot.

Hope that helps.

Ahhh I see I see, I was wondering how there could have been the interlaced artifacts even though it looked like an original progressive image when played. I didn't know the P2 mobile could do such things!
That means that the original clip looked even better, because we are looking at a second or 3rd generation file now and it holds up very well.

Alex,

It seems skew is easily induced by (obviously) pans that are too fast, a lens that is too long, a combination of the previous two or quick jerky direction changes on camera moves. Ben D's pan shots of the fence although exaggerated, demonstrates this last one clearly. I saw this phenomenon when trying to hold a hand held static shot at the longest end of the lens.

The skew issue is one of those things that everyone should try and check for themselves as you did. I found it helpful to execute shots that I commonly shoot, and shoot shots that are consistent with my style. I'm under no illusion that the cam is skew free, nor will I able to throw caution entirely to the wind in regards to skew.

I wonder if the skew decreases in 30P compared to 24P ? There isn't a 1080 30P test that I know of.

If you get a hold of the settings on the green screen footage, I'd be curious to know what they are. An additional "Noise lite" recipe for the camera would be nice to have. A collection of these might be a nice sticky.

I can't do the Pro Res conversion for you as I'm on FCP 5... or does it have Pro Res? I'm not in front of my work station at the moment. You may have to help me out with the upload, but I can try to get to it in the next couple of days.
 
I posted this before but you will get skew in just about any viewfinder. I did an off the shoulder long lens/crazy panning skew test with my dsr570 and it skewed terribly in the vf. I have used this camera for many years and never seen it because I never pan like that ( granted I know it doesn't record like that but the vf does skew and I have never noticed it ). I've been shooting with my 300 for a few weeks now and skew is a non issue. I've shot cars people riding bikes, shots from moving platforms sport as well as interviews and standard eng type stuff and all I can say is this camera is great. The only issue I have is DOF but I knew I was compromising going in. This is the first 1/3 inch cam I've owned ( coming from a 2/3 background that extends to 3/4 inch tape days ) but I am finding that I can work around it and still get great images. I don't think I have ever bought so much camera for such little money.
 
So true.

Let's hear it for Tk-76's, M7's and 110 decks.... uggh ;-). Back in the day I shot with a three tube Betacam. My shoulder still feels it. Light weight cameras are a good thing.

Your last line says it all. So much camera for so little money. I find myself at times in awe at how much the technology has improved and how the price has diminished at the same time during the course of my working life. It is truly astounding.

I have a shoot this morning, but I'm going to pick up my 300 from the dealer this afternoon. I am super stoked !

That's the situation for me. I don't move the camera too fast but I do handheld and I like to use the tight end of the zoom...

I've contacted the cameraman of the green screen shoot and he was very pleased with the camera. He did not mentioned any particular setting, he's one of those "salty dogs" cinematographers having used many cameras throughout his many years of experience, didn't say much other than: It's a good little camera!
If I have the opportunity to post some grabs of the finished work I will do it, but I'm just a consultant on this job.

I have the impression that for the next few months we'll be seeing a lot of footage from this camera, Panasonic hit a sweet spot with it and with the addition of the E series cards we now have a truly pro P2 package under $15k.
 
I shot some cycling with it, training for an endurance ride, that's the sports I was referring to. I've also shot tracking footage of cars and it worked out ok. The tracking shots I took from a vehicle worked well too. A lot of the footage was fairly wide, long lens you can see some effects of skew but I found I could easily get around it.

It's early days yet but so far I am happy.
