HMC-40 test footage

Hey guys,

Here's some more footage from today where we finally had some decent, non-rainy weather with no fog. :)

This was shot using the Panasonic HMC40 on 1/2000 shutter speed at PH720/60P, starting at 0db gain and going up to 12db of gain. And, slow motion, as well:

I'm also going to upload all the raw, un youtube'd files here available for download. They're not raw .mts files, but full resolution adobe premier outputted files in .mp4 format: http://www.utvreport.com/videos/hmc40tests They're in the process of uploading, so it will be a bit before you can download them...they're big, because I uploaded these at full 21 mbps.

Here's a few more videos:

This was shot using 1/250 shutter speed, testing from F11 - 0 db open:

This was shot in auto mode, but manually adjusting the iris dial, which was weird. I believe the dial corrects/adjusts a lot faster than the display is able to tell you what's going on. It was hard to tell if I was adjusting the gain only or the f-stop, as well.

And, this was shot to try to determine up to what shutter speed I could effectively keep the gain at 0 db. I was flipping between agc and mgc to see if the camera would display the level of gain in manual gain control after running it in auto gain control. I'm still not quite sure, but I think it does.

Because you are trying all sorts of tests, here's one that should prove to be fun....

When the lighting is reduced (like after sunset or night), try shooting at 1/60, 1/30, 1/15, and 1/8 of a second shutter speeds. I assume that you'll have to adjust gain or the iris to make the exposure the same for each test. It should be something with motion, like a street scene with people and cars going by.

If you also try the 24P setting, try 1/48, 1/24, and 1/12 of a second.

Here ya go...this was all shot at the time I thought with no gain, but this was actually at 24db gain on auto gain control. Actually, the camera comes preset with the maximum gain of 24db and does it automatically as it sees fit, and you have no idea what it's set at unless you do it manually. http://www.youtube.com/watch?v=z7I5KEWRmrE

Hey guys,

I just realized to my surprise that all of these low light videos I posted were shot with the gain set at 24db. To me, from the statements I've read, you don't want to go above 12db, so after reading the manual and figuring out how to change it, the rest of my videos were shot with the max at 12db. But, the following videos were shot in full auto, auto gain control, and because of the low light I'm suspecting all at 24db:

I don't think the above videos look bad at all at 24db, personally. What do you guys think?

Here's the rest of the videos shot with the gain maxed out at 12db, but these aren't all shot in the dark like the above ones. These you'l notice are tests of the gain, shutter speeds, auto gain control vs. manual gain control, digital zoom, white balance, and chroma levels, as well.

All of the above videos are being uploaded here: http://www.utvreport.com/videos/hmc40videos for download if you want the uncompressed files to watch on your computer versus YouTube. The dates of 10/12, 10/14, and 10/15 are all shot using 24db gain. And, 10/18 are the ones listed immediately above this text.

All of the videos aren't uploaded to the server yet, but I think all the 10/18 ones are already. The others are uploaded as we speak. You'l also notice that the videos on 10/18 are much larger than the rest. The reason for this is I outputted them from Adobe Premier at full 21mbps, instead of 6 mbps for all the rest. I can't tell much difference...can you guys? I'm not sure it's worth the extra size, download and upload time personally. I've found too that the best way to play these to see issues is at full screen, not the standard YouTube size.

I hope this helps...if anyone has any questions, please don't hesitate to ask. These were things I wanted to know before buying the HMC40, but I couldn't find out there, so I bought it. :)

Here's some testimonial videos I put up on Youtube from my Glamis, CA dune trip.

All of this whipped together as one video for the SEMA show that just ended...all rough cuts, very little editing done to make them look more professional. I'm very impressed with the camera, and I've found that my matthews tripod when shooting today is a huge help. I'm shooting out in UT today and the next two days, and using the tripod makes all the difference in the world for quality shots. I played it through component out as 1080i, even though I shot it in 720/60p, and it looked outstanding on the television today. Unbelievable actually. The exposure was spot on, colors at +1 chroma look great. So far, I'm very pleased with the camera.

Here's a video I just completed:

http://www.youtube.com/watch?v=o4utezpM6s8

It was filmed using the HMC40 in PH720/60p with the following setup:

- Panasonic Wide Angle .7x Lens
- No ND Filters
- Rode Videomic with Dead Cat for Sound
- Matthews M25 Tripod
- OIS On
- Slow Motion is 25% of normal speed
- Edited with Adobe Premier CS4 on a Macbook Pro 17"
- Outputted using Mainconcept H.264 Youtube HD preset, but changed the fps to 59.94 from 24 fps.
- +1 Chroma

Any pointers, comments, or suggestions would be greatly appreciated.
