The video was shot few days ago when i was in Japan for family and developed in Sony platinum on the laptop.

 

 

The lens were used in video were Noctilux F1.0 and 18mm F3.8.

 

My M camera shows horizontal black strips on my image across the whole screen. Sometime has it but sometimes it doesnt. I will still want to get it fix. I bought the M just few month ago and now it has this problem.

 

Anyone has horizontal black strip across whole image problem ?

I watched five minutes of it and did not see one black stripe. Is it your computer?

[digi2ap]

No black stripe that I could see either. Does it occur throughout or just during specific sections?

I've downloaded the complete video and see no problems in either the Quicktime or Video Lan player. Suggest you may have a problem with the Codec your player uses.

Hi Michael, no black lines for me. However I could only watch the first minuet or two before the the shaky video got to me. If you are using a Mac you could run the video through iMovies to remove the shake:

 

iMovie '11: Stabilize video motion

 

Or Windows:

Windows Movie Maker: Stabilize Shaky Videos | a Tech-Recipes Tutorial

 

I hope you dont take offence with me saying this.

You mean at 1:28 for example? It certainly isn't a reflection as it is fixed in frame while the camera moves. There are also a few spots where there are dark bands that flash up. It's almost like an old silent film

 

The rolling shutter on these is absolutely terrible. I am guessing the scan rate is way low because any movement and it chops things up to hell. It actually makes me feel uneasy, I could only watch a couple minutes of it.

My guess is it's a timing issue between the rolling shutter and flickering artificial lighting.(it happens so fast you can't see it with your eye) . It's a common problem and partly the reason why the motion industry spends painful amounts on flicker free ballasts. It's going to be exacerbated by this cameras slow shutter scan I believe.

may I suggest using a tripod or at least a monopod for next time?

that will address most of the criticisms here.

or use a 35mm lens (or wider) if you really want to go handheld.

 

but to answer your question: no I did not see any black strips viewing on my MBP.

I’m not so much bothered by the wobbles - Cinéma Verité and all that- as by the overdose of focus pulls. After a few minutes I had seen enough shifting planes of focus to last me a couple of years.

I've just spent two weeks in Colombia on a commission in which I've had to do much more video than I'd wanted to! I've had to work in really crappy light in some cases (shooting at SLOWER than 1/50th reduces some of the flicker issues that arise from neon lighting), but had had no disasters and no black stripes. I've always used a tripod for these jobs, and have worked with either 35 cron asph or 50 lux asph and have done my best to stay above f4 - and this has often necessitated working with 1600 ISO.

Overall, apart from the real drag of having to leave renders running overnight so that the backlog of work doesn't overwhelm me, I've been VERY happy with the results from the M240 - as has my VERY critical client. In earlier commissions I've used the Canon 5D2 for this kind of project and it's been great not having to hump this around + Canon lenses.

 

My opinion is that for a limited range of video applications, the M240 is absolutely fine. I have no desire to be a videographer, but for those occasions (which are growing?), if the client requires video interview footage alongside still photo-documentary, I have NO concerns using the M240.
