6 mbps conspiracy?

OK, what's the deal? How come no-one's managed to post any 6 mbps footage? Some people have said they would... and that's the last we hear of them. Lew's footage request thread is lively and active... and I request 6 mbps footage, and the thread dies!

I sense a conspiracy.

A pact? "You guys will get your cameras early as long as you NEVER post 6 mbps footage on the web! Ha ha!"

A miracle? "I can't post this 6 mbps footage... noone will believe me... it looks so much better than the PH footage!"

A bad sci-fi movie? "I can't post this 6 mbps footage - the s 6 mbps mode lowers the data rate by not showing clothing!"

A lack of free time? "Well, if I show 6 mbps footage, I'll have to shoot four times as much footage generate the same amount of data. Who's got time?!?"

A coverup? "The 6 mbps mode looks like a series of images made with a Lite-Brite! And the Refresh rate's about the same!"

Or just coincidence.

Please, someone, post some 6 mbps footage. Some with a normal shutter, some with a 1/30th shutter, ideally. PPPPLLLEEEAAASSSEEE!!!!!!!!!
 
I'll try. I think people are just too excited about the 21mbps to care about the 6mbps.

Now that's damn funny!

I don't have time to upload footage, but here's a screen shot, downsized for the web of course. Now stop whining. :) (I'll actually have my 150 in a couple days and can help then if someone else has not by then)

Try this.

Took me a while to figure out how to get it in this mode. Yeah, it's not very in focus, sorry.
 
Hey, I did post some 6mbps stuff. Well, okay, it was the rain clip, so it was only a few seconds of the worst-possible-case scenario... but frankly, I think people don't shoot 6mbps because you can only do 1080/60i at 6mbps, and who wants that? 720p and 1080p are only available in PH mode.

That said, someone help a brother out.

We don't have a 6 mbps mode. Only PH AVCHD at 100 mbps.
Panasonic gave us free cameras to hype it up and to get people to buy them.
Your camera will have the 6 mbps mode.
You poor soul.

Oh yeah they gave us 5 free 120 gig SD class 12 cards too....
I like Panasonic!:beer::beer::beer:
 
Durrrrr sorry for not getting that 6mbs footage =X must have missed it. Regardless... if you're going to spend close to 4 grand on a camera what's the point of using the lowest quality mode shooting in interlaced? There's just no point honestly.
 
There is, though -- 6mbps mode gives you 12 HOURS of continuous recording. For event shooters, that might just be what they need.

I never thought of that really. Good point. I think I'll take some footage tomorrow during the daylight see how good the quality is. I have a feeling that the quality of the lowest on the hmc150 is probably better or the same as my old hv20 footage

Wait the HMC 150 can adjust the megs per second?

It has 4 different recording modes at different bandwidths:

6mbps 1440x1080 @ 60i
13mbps 1920x1080 @ 60i
17mbps 1920x1080 @ 60i
21-24mbps 1920x1080 @ 24p, 30p, or 60i
21-24mbps 1280x720 @ 24p, 30p, or 60p

So if you need mega recording time, you could drop down to 6mbps mode (I think it's called "HE" mode, for Highdef Economy). That'd give you about 4x as much recording time as the 24mbps PH mode (for Professional Highdef).

Hi dudes! Thanks for all the replies! Thanks for the footage, kurtmo! It's not ideal lighting, but I'm encouraged by how the zoom is handled!

As for the reason: this cam is being purchased for a university music dept. that can only afford one decent camera. While at some times we'll need very high quality acquisition, we also will be capturing 5-10 hours of footage a week that needs to be archived easily, and potentially never looked at - and if it is touched, it will be used for web-video "highlights". So, we need one camera that will provide top-quality prosumer performance, and also produce "passable" video that can easily be archived (that is, about 90 minutes [typical concert length] on a single-layer DVD). The promise of filling BOTH these roles is the great promise of the HMC150.

For my personal use in other endeavors, archivability still remains an important factor, though I'm more likely to be using the 13 or 17 mbps. I'd potentially use an HMC150 mostly as a 2nd, steady camera for opera/theatrical productions. The 1080 would be likely be scaled down and sometimes re-framed down to SD. Sometimes my clients take up to 2 years (so far!) to make editing decisions, and I need to keep the raw footage around in a very secure way... I've currently got about 1.5 terabytes of material from P2 on hard drives, which keeps me perpetually nervous! I'd love something smaller and more easily backed-up onto some offline media. Here, I'm interested in seeing how well I can "fake" 30p with a slow shutter in some of thew lower bit-rate modes. And if indeed the 6mbps mode does a halfway decent job for this, it might find some use in at least some circumstances!

So, for me, the great appeal of the HMC150 is the "workflow" enhancement that results from the low bitrates. This is true at 21mbps, for high-quality work, but especially rare and true (I hope!) for less quality-demanding work at 6mbps. Easy archiving, fewer worries about when to schedule a card-change during live events, the ability to leave a camera running unattended for hours, etc. The typical concerns of most DVXUsers - transcoding time, etc - are not such a big deal to me. At the time when I DO return to a project to edit, I don't mind having to transcode to a more data-intensive format (e.g., ProRes) on a scratch drive for the short editing time... I'm much more concerned with storage issues of the raw material for the indefinite time it takes to get TO the transcoding/editing process!

Thanks for listening!

Sorry! I didn't mean to discount the beautiful rain footage!

And, yeah... I would have preferred 720 (especially 30p!) for the low-bitrate modes, and it would have made more sense, quality-wise!

Great! Thanks! What were the scene file settings for this look? I'm really impressed that both the sun and the face can be properly exposed - were you using DRS?

DRS was off, and see how well it did! Tee hee! :)

I appreciate that you better spelled out your usage in detail. I do plan on using the requests on the boards here to 'learn' the camera, its settings and HD in general. I am going to do it quietly, though, and post when I can. I'll probably give your scenario a go. Cam should be ready to roll footage Thursday am - after the battery is charged up.

it has different "modes"

Only when utilizing the Flux Capacitor!

Seriously though, would the 6mbps mode even at 1080i be better than the DVX's image?? If not and its not as good as DVX progressive SD, I agree, why even use it?
I'm saving up for mine now, probably get it early next year, you see I gotta fork out an extra $1000 or so for mine here,,, they are $5495.00
 
Well, I assume the 6mbps would look fairly bad compared to the other bitrates.

The HMC is compressed enough as it is.

But that's why it's 3,000 and not 18,000
 
Hey thanks Thomas, it's not too bad actually. I can see it being used right now during speeches & toasts at weddings or conferences where there is little camera movement or panning.

Nice one!!
