maybe the flickering is linked to the amount of grain of the adapter. the walls are darker than the room, the grain is appearing more easily on this part.and the compression is messing there.

Should we wait another day or two? should I throw my 2c? (hint only!) or should I ask another question? what would you prefer?

how far are we from your own explanation? =-)
 
my explanation... yours... anyone else.... should be supported by a practical test, or, (if that would be impractical) by a solid theory that does not need testing and unanimously accepted to become "the explanation". This is the only way to keep the contest fair to all and rule out errors, don't you think?
 
ok i shot this example: http://www.supralumen.com/flickering (look at the corner of the table on the left)
it's some european fluos. a dvx100 pal. and the same flickering. but the autofocus is on. nothing happens when it s off.
it must be the difference of frequency between the fluo and the autofocus seeking speed. a bright area, a darker one and it happens.

Dan, I would keep it going for a while. Let some more people find there way here.

The prizes are great and worth waiting for. I really like some of the ideas that have been listed. I still haven't been able to see the clip on anything more than my 12" laptop screen, but if I were to guess I would say it's paranormal activity or something to do with being near true magnetic North. :)

I can't wait to get my gears. Thanks. :)

Good luck everyone.
 
moving gg? or VINGNETTING in the left coners like the the ois is on or Maybe they zoomed out a bit?

I got Dan, I got it! I've been looking at what I see and I'm pretty sure they weren't practising safe sex :-0 As for reproducing that, I'm not sure the world is ready to see me replicating the shot.

Yer a sharp dude Andy!

The movie was shoot using a DVX100A for a ...... FOR SCI FI CONTEST intended distribution. That means the camera settings must have been such'n-such 24P. Under those circumstances, OF PAL OR OTHERE CAMERA LIKE THE FX1 this'n-that is not possible, therefore it mush have been 25p or 50i (as the only choice left)

Well.... don't be so hard on yourself, you could be behind the camera (for a change)

On a general note, I think we have one winner (imo). To keep it fun, educational and entertaining, should I provide the first winner with my guess and still allow him to be in the game, providing contra arguments to all those do not suit his view, without letting anyone else know who he is and what he knows?
Or should I not reveal the winner? (not even to himself) so he will keep supporting his POV regardless?

Or... should I just send him the lens (without my "2c" but with compliments)?

What do you guys think? Remember... there is still one more lens and three gears left. And they all have to leave. Education should be fair, fun and free, right?
Yeah right!
 
I think you should reveal the winner and come up with another contest for the other prizes :)

Hi Dan,

How's it going?

I agree with ASG, this is very fun!!


Like the other guys said, you should start your own thread.
 
OK now, but hear this: what if?..... what I think to be the cause (and based on that belief choose the winner) but most of you do not agree with the cause and the decision? I don't look good and definitely not fair. The contest looses popularity and definitely you don't learn too much in the process.

I think we should all agree that "this'n-that" IS the only way to get "this'n-that" and only then move on to a new thread. The reasoning must come from you.
Agree?
Based on how many readers this board has, we should wait and listern to other opinions as well (imo, lol)
 
If the problem we are discussing is the flicker, I reckon it's definitely caused by doing 50% speed on 50i, here's what Macgregor himself had to say about it on DVinfo, albeit with HDV:

"I am starting to get upset. Everytime i make a slow motion from HDV 50i to 50% speed, some parts of image start to flicker.
Does anyone notice this?

Here is an extreme example of the problem. Sometimes you dont see the issue. Sometimes footage becames unusable.
How can we fix this? Why is it produced?

thanks!"

and:

"The shutter speed is 1/100.
Remember this is recorded at 50i because i am in a PAL country.

Slow motion has been done in Vegas, setting speed at 50% so from each HDV field you get a full rame. At SD resolution i get very decent images.
However some parts of the image sometimes flicker, speacilly with some colors. Skin tones suffer the most. Si i guess it has something to do with color compression.

This is an example of medium flicker. Look at the right part of the girls´face and her shoulder. there is flickering there and it is not a problem of QUicktime sorenson compresion.

and:

"Quick reply:
I use 1/100 because it is the way to go as a film camera would do.
The flicker is not a couse of artificial light. both clips have sun light.

The slow motion is done by setting the playback rate at 0,5. It is the same as if i would apply a velocity envelope and set it to 50%.

Then i render a 25p video. It doesnt matter wather it is full res, wmv, avi, mpeg, the same issue appears always even in the preview window.

There is no need to apply any deinterlace method. Vegas does the interpolation from each field atomatically.

I´ve done this with footage from DVX100e, xl1, pd150, betacam and DVcam and never had any problems."

It was shot in Madrid and Lanzarote both 240V 50Hz power supply, PAL, 25fps. So if it was shot 25p on the DVX why isn't there frame blending on the slomo...

make up your minds guys, you are postings contradicting statements;
Was it shoot on DVX100e or an HDV camera?
I allways knew it was DVX, now I see talks about HDV.
What was it?
