What I learned about my little HMC40

Well, I had some fun this weekend since I volunteered to record a music festival at a local pioneer village living museum. This was the first I’ve run-and-gun so much with this little camera. Also remember this is a hobby – I’m no pro and it shows!

https://vimeo.com/44304647

What I learned:

- This is a great camera for the purpose. Small, light, not too expensive, and stunning images.
- The lighting was mostly outdoors, so not a problem. Many backlit scenes had to be manually adjusted.
- I relied on the autofocus too much and it often let me down due to music stands in the foreground, etc. Given the small screen, I didn’t realize it until later. Lesson: always zoom in and use the focus assist. I’ll need to be able to find it without taking my face off the viewfinder (the LCD was mostly washed out in the sun, so I did most of the outdoor shots with the viewfinder).
- Auto white balance mostly worked. The worst case where it did not is the scene with firewood, where the white balance changed to the log cabin, and the white mortar was greenish.
- Daytime window lighting was enough for the indoor scenes. The only high gain scene was filmed by candlelight, and it is grainy.
- The zebra stripes worked well. I left them at the factory 80% and the scene with the boy in costume his sleeves were all zebra, but I filmed anyway. It is over exposed.
- I used an external mic and several times forgot to turn it on (did not want to run around with headphones on). Silent video of a music festival is not a good idea.
- I edited with Avid Studio: nice price and does the job for me.
 
Hey Steve

Great and interesting footage and shows what the HMC40 can do!! I have two HMC82's (the 50i version of the HMC80) which is just an HMC40 in a bigger box and XLR audio. I still think the cameras are awesome!! I recently upgraded to the new AC-130's and was bitterly disappointed at what they can do for more than double the cost..they are now on-sold and I'm back with HMC82's again!!! I have made a habit of turning on my external mics before the cameras come out of the car and I leave them on!! A new battery is easier to fit than having no audio!!! Mt buddy in Wisconsin used to have a sticker on his camera saying "TURN MIC ON"

I've set my zebra stripes to 105%, that way when I see them I know that it's going to be blown out.

90% for me is a nice level for general stuff. If you are critical about skin tone and need to expose for that then 70% is the way to go!!!

Hi to all, and thanks for the comments.

Regarding the zebra setting: after I saw the stripes on the white sleeves of the kid -- when I turned them down everything else was too dark (including his face). I had to accept that part would get blown out (without adding more light to the rest of the room). I think I like the 80% because I'm getting used to it. It puts enough zebra striping area in the viewfinder to warm me to pay attention (to turn on WFM if I really was into it and my subject was stable). To be honest, I've never fiddled with it, so may try that some.

Bob for me 95% has worked well for blown out highlights, don't you think 105% is a lot ?

+1 on that. By the time you hit 105% it's too late.

Bob, are you using much knee to make this work?

If I just touch 90% in the brighter areas, that seems like a good place. If there is a larger amount of range, I might go a little higher to get the dark areas exposed.

It's all a matter of personal taste. IF we go by ideal IRE levels, 100 should be the maximum. Setting at 95 warns you before you hit that level; however you may be seeing a warning and you're not at the real blow-out level.

According to the digital number recorded to memory, 100 IRE is recorded as 235 and 109 IRE comes up as 254. I assume that 105 IRE comes in at 245 or 246. From an analog signal standpoint we have clipped, but the digital signal has a tiny amount of room to correct.

If I see clipping occurring, I stop down by 1/6 of a stop, the smallest F-Stop increment on the camera. 1/6 of a stop = 89% of the light. This means that after stopping down in 1/6 of a stop steps, the IRE level could be anything from 94 IRE to 104 IRE; the average would be 99 IRE.

Except for run & gun shooting, where I'm forced to used auto-exposure, my exposure is set using the waveform monitor. So, Zebra is only a last minute warning for me.

Hi Bob

That makes sense if you have the time and situation to use the waveform. Mine is all rush rush run 'n gun at mainly weddings so 90% sorta suits me anyway and it seems to avoid any blowouts so far. Then again running 3 cameras solo I don't have the luxury of manual iris so it's mainly auto except for the wedding ceremony where the main camera is in manual . Everything else at a wedding apart, again, from speeches where the main cam is in manual, is full auto as thing happen so fast!!!

I'm actually contemplating an HMC40 for my stedicam as the HMC80's are a load to carry and balance and I reckon the 40 would be just perfect!!!

After a retest considering this thread 90% is fine as a general purpose for my personal taste Bob, however you have to do what ever works for you

Steve, I enjoyed your video and thought the video quality on Vimeo was really good. Although I edit in Adobe CS5 and might not be able to match your settings, what resolution and bit rate did you upload with? I typically film in 1920x1080 at the HMC40s top bit rate (24 Mbps), but I upload to Vimeo at 1280x720 at a targeted rate of 10 Mbps.

Hi, Dave-

I'm glad you liked the video. Here's the settings I used:
- Camera: PH 1080 30p. It seems to work uploading to Vimeo, YouTube, and burning Blu-Ray discs for home after editing. Good enough for me. And I get plenty of time on 16 GB cards.
- Software export and Vimeo upload: MPEG-4. I use the mpeg4 preset (Avid Studio is really just a high-end Pinnacle product) for h264, 1920x1080, 12,000 kbps (I would think that is 12 Mbps, but in the binary math world it could be different but close), 29.97 frame rate. That 10:13 video I uploaded was an 835 MB file. When I uploaded to Vimeo, they do warn me that the 1080 will get down-scaled by them (to 720, I think). I do it anyway, because I want to have just one mpeg4 master file. I uploaded the same file to YouTube, and they can keep the full 1080. If you want to compare, here's the link: http://www.youtube.com/watch?v=Ilb5Ev3Pb7w&feature=plcp
It's from exactly the same mpeg4 file as I uploaded to Vimeo.

I barely know what I'm doing. The discussions here have helped. It all seems to work, so I'm happy.

On a side note, I'm looking forward to the fall pioneer village volunteer gig, because it will feature a large group of civil war reenactors. The lady that runs it said I could run amongst them (general public not allowed). I have to get some kind of steadycam for that!

Steve, the video looked great. I am curious why you chose 1080 30p vs other choices (i.e. 1080 60i tv look or 1080 24p film look)? For instance, did it give you the look you wanted, or did it seem to work best when burning Blu-ray, etc? I can't remember what the "native" format is for Blu-ray but did that factor into your 30p choice? I certainly agree with your statement "it all seems to work so I am happy."

I don't do a lot of video (a hobby when I get time), but usually film sports car races at 1080 60i and then burn Blu-rays to give to friends (or DVDs for those who don't have Blu-ray player). The Blu-rays look great even though I think 60i is not their "native" format--probably my editing software makes the necessary conversion for me when burning Blu-rays. Dennis

Hey Chris, what was the big let-down with the AC-130's ?

I am still using my HMC-150, which I am still very happy with, but I'm curious about what you didn't like with the AC-130 ?
 
Hey Dingo

I shoot mainly weddings and the autofocus mainly doesn't work...it drifts all over and if a subject moves out of shot they come back in totally out of focus..I'm running two cameras all the time and although I can go totally manual, I was disappointed that a feature on the camera simply didn't work and Panasonic claim "it's a different system" .... However the BIGGEST thing without any doubt is the fact that footage has NO WOW factor at all....my HMC82's have it and HMC150's have it and my theory is that the new cameras don't use Leica lenses !! I really don't think they have the same result at all...footage is really and truely "flat" 150 images jump out at you!! I used them for close on 80 hours each over 3 months so I think they got a fair test but after that I decided to change back to my old cameras as I prefer shoulder mount anyway despite the small chips!!! The first bit of Realty footage I shoot last week when the HMC82's arrived again had a WOW factor ...big relief!! A lot of people use the 130/160 but I was less than impressed!!

I also found that auto iris only controls the aperture and doesn't do shutter switches like the HMC40/80 so outdoors you and constantly switching ND's in and out...the fact that it needs 4 ND's and in sunlight you need a 1/64th filter or you will over-expose..a cloud passes over and you need another ND change so it was impractical to use two cameras working solo!!!

Just realise that is my take on the situation ...others seem to enjoy the camera!! I watched my weddings over April taken on the 130 and then ones in January with the 82 and you can see the difference!! At double the price it should have been the other way around!!

Hi, Dennis -- kind of like asking which is the one true religion, isn't it? From my camera I want the max it can deliver: PH and 1080, since I figured I can down-scale later if I need to. I picked progressive since I could get better still frame captures, although I haven't done that yet. Plus, it works with all I need to do. Also, I'm not delivering to any media outlets that have a particular requirement. And my opinion is that the cinema look (24 fps) is not what I'm after (honestly I can't see much difference, but I haven't tried it much).
-Steve
 
Thanks for input Steve. As you will discover one of the benefits of this forum is learning from others so I am always interested in the "whys" and it does often come down to individual preferences. The camera has so many features even after one year I have barely tried all the options. Dennis
