I am having problems with single camera shoots with the HMC80, if I am shooting more than 25 to 30 minutes in 1080P, camera starts a new clip, in post I have a chopped audio and video, are you guys experiencing the same issue, for some small shoots I don't want to go into the trouble of using a second camera and or an external recorder.

HMC80 4gb file limit

What NLE, and how do you Import clips? When you say chopped, do you mean that a few frames are missing between clips? If using Premiere try this. Copy the ENTIRE folder structure from SDHC card to hard drive, do not pick and choose video clips. In Premiere, rather than "File > Import", use the Media Browser. This should tie spanned clips together behind the scenes, and then when you add to timeline you will get unbroken playback.

Are you using the IMPORT TOOL that's built into almost all modern editing software to transfer your video footage from your camera's memory cards to your computer's hard-drive ?
The IMPORT TOOL will read the meta-data stored on your camera's memory cards and stitch together all of the separate 4GB video files into one larger video file on your computer's hard-drive.

To echo what they're saying -- there is no problem with your footage, when handled properly. The HMC80 is designed to make seamlessly-spanning clips. If you import the footage properly, you will have perfectly seamless footage with no glitches.
If you just drag files to the timeline, you'll have problems. But if you use the proper import tool (and, as sharbor said, in Premiere it's the Media Browser) then you'll have a perfectly seamless experience.

See, that's where you got it wrong. You DO need to copy those files, or else you get the missing footage problem you were encountering.The folder had other files I did not need to copy,
yes, if you want the footage to work properly.do I have to always copy the full folder to my drive.
Most of my shots have been less than 10 minutes in the past so it's never been an issue till now. After I got the camera I went through the manual and your book Barry somewhat quick and must have missed this detail. All along I have been going to the stream sub folder and only copying the shots I need. I know better now cheers. Barry will the HDMI on this camera allow 4:2:2 external recording?

Yes, the HDMI output is a full 4:2:2. Glad you got the issues sorted out!

The HDMI output is independent of the recording codec. The HMC40 does output a full-res 1080 with 4:2:2 color. If you were to record that to a BlackMagic HyperDeck Shuttle 2, yes you'd get a ProRes recording of full 1080p 4:2:2.
Just be aware that many folks have compared onboard AVCHD with external recording and come away scratching their heads as to why they didn't see a bigger difference. Lots of folks haven't been able to really see much, if any difference. AVCHD is really pretty good. If you're doing something involving keying, the external recording will be superior. If you're doing something involving lots of moving fine detail (like a forest shot with billions of leaves blowing in the wind) the external recording will definitely be superior. If you're doing something like interviews, I think you'll be really hard pressed to tell any difference at all...

Thanks Barry,
I own both a hmc40 and hpx170. Despite the significant differences between the cams, by working at matching the scene files, I've been able to cut these two cams fairly well with the HMC40 being slightly sharper. They both have that familiar Panny mojo and the scene file adjustments confirm that except that usually the scaling of the adjustments is different. And you are spot on about the avchd breakdown with leaves motion as I have done that exact test and the DVCproHD files are much better, no doubt due to the I-frame codec.
I wonder why the prores recorded files from a HMC40 or 80 wouldn't have a larger difference compared to the internal recordings.
The little 40, despite its drawbacks, (viewfinder and low light) is still a terrific cam several years after introduction. Feature rich and great IQ for not much money.

Barry is right on with his assessment of external recorder quality. Think about it - you shoot some well-lit footage on your AVCHD camera and then view it on the HD TV and it looks just beautiful, right? A lot of folks seem to think that if they record the same footage with the Ninja 2 for instance, that it will somehow look obviously far superior. But the difference is in the DETAILS, and it's more evident to your KEYER or color-correction chain than your bare EYES. Other benefits of an external recorder are being able to record all day without swapping multiple cards, and recording to a more edit-friendly codec.
A good example is HDV footage. If I view the playback, it generally looks quite good to me. But if I look at still frames in the NLE, I see horrible compression a lot of times! But you don't notice that much during playback, it all blends together. I've seen many YouTube videos with split-screen comparisons of camera clip vs. ProRes from Ninja, and even on those I can't see the difference that well.
The way I spotted a difference with my own footage was to grab stills of the same moment in time, from HDV and ProRes, layer them in Photoshop, then toggle the top layer on and off. It helps to zoom in on something, for instance a face during a stage event, then toggle and watch the eyes and mouth appear and disappear, or look at the background and see the large blocks of color versus smooth gradients of fine pixels.
The funniest clip I saw online was a locked-down close-up shot of a flower in the garden. No motion. And the poster complained that the Ninja clip didn't look any better. Really?
OK, done venting
Thanks
