Guerilla35, Any Updates??

macgregor always stated that similo was shot with the pal dvx100.
it was shot in europe.
so everything is fine with the products compatibility (50hz)
he shot in 25p. but for slowmo he's using the 50i method (not timewarp or anyother interpolating plugin).

right?

Anyone has any problems with the above statement? True or false?
The credits show it was shoot in Madrid and (another city) both in the 50Hz zone.

Side note:
(The G35 team must enjoy this popularity contest tremeduosly to keep aside without one single comment (not even from the originators of this thread).
Ehh...too bad they don't want to play with us... )
 
It's amazing what this thread has turned in to.............

Maybe Jonathon will see the title of the thread, pages and how many replies and think it's all for the Guerilla35 and start shipping them.......
 
this shoot is slowmo.
we can notice some flickering on both sides. some vigneting slowly appearing in the lower corners. some black dots in the lower left side which are moving.
it looks like a dezooming .... or something moving (a little bit upward maybe).

Thanks Ill Eagle (did you watch the clip? any comments on the subject?)
So far, it looks like the word "flicker" and flickering has popped up too many times to ignore.
Has anyone any doubts about its existance in the clip?
Delaro brings up a very good point (very good observation) but not a real explanation (just a guess)
 
maybe it s because the g35 doesn't have any rods, and when macgregor shot this scene he was trying to focus and bended the adapter a bit with the focusing hand. so we can see everything going upward and the dots and the grain are disappearing in the same time with the good focusing.
 
and i noticed that this flickering can be found in a lot of shoots in this movie. at 3:35 for example around the neck and the face, and the next shoot, .......
maybe it's just the compression which is messing with the grain of the adapter. and when there is a specific amount and mix of light, blur and grain the flickering appears.

if you're looking the movie between 1:43 and 1:50 i'm pretty sure this has been shot without the adapter (macgregor said that he forgot it one day). no grain, great depth of field,very sharp. if we compare this one with the one around 2:10 (with the adapter) and the one around 2:16 for example (adapter too) we really notice the flickering on the girl when macgregor used the adapter. but not on the part without the g35. so that would mean that its not a problem of fluos frequency.

So, you found other spots in the movie with the same flicker, hey? (I must watch it again)
Nothing outside? On the road? (the sky, the road itself?)
I don't have a DVX, HVX nor any other recent cameras (except a SI sample from Ari) and I don't remember how they behave (or don't!).
I did used them all for some time but I am not an expert with any of them (I still have some footage from both but is soooo old).
How about we ask an expert in this cameras to share his view? Barry? What do you think could cause that annoying flicker?
 
look at 4:18 on the right side. shot outside on the road.look at the girl cloth. same color, this dark blueish white, as the wall. same flickering.

at 2:22, lot of flickering in the sky.
its definitly not the frequency of the fluos and not the autofocus.

it's just that the adapter grain is not visible on the very bright and very dark areas of the image. but a white wall a little dark shows it a lot, and then the compression creates the flickering.
it's very noticeable on the girl skin too on some shoots.

ok it's 6.30am in paris. time to sleep. :-)

Macgregor said that it's not the compression. I get it on my GS400from time to time (with or without adapter), in daylight shots - when you slow interlaced to 50% one frame is created from the even interlaced lines plus odd lines averaged from the two either side, then the next from the odd lines plus even lines averaged, and it's like the frame created using the odd lines is slightly blurred compared to the one from the even lines, which creates the flicker. It's either the way the camera captures the odd vs even lines, or it's the interpolate deinterlace, or both.

I agree it looks like no adapter at 1.43.

I'm also seeing 2:15 - 2:20 (on the bed). If you watch the socket or whatever it is over her head, go from in focus to out of focus really quick, there's definitely no adapter used in this part. Or I'm really tired and my eyes are playing tricks on me from watching this clip over and over.

I've even tried rendering a clip out twice interpolated deinterlace, once as upper field first, once as lower field first, then shuffle alternate frames from the two clips to slow it to 50%, and the flicker is still there, so I think it's an in camera thing.

I agree it looks like no adapter at 1.43.

so yes, if macgregor has the same result with the uncompressed footage it must be the slowmo with the interlaced thing.

at 2:15 the glass grain is noticeable.
 
VINGNETTING encroaching in the left corners like the ois is on or Maybe they zoomed out a bit.

anyone going to Back me up?
 
Rest assured, help is on the way. I PM-ed Barry (I don't think he noticed the thread) and he should be able to help us. Here it is:

Barry,
I have noticed something unusual in Similo and I posted here:
http://www.dvxuser.com/V6/showthread.php?t=60437&page=6
Although many people have (or have used) the DVX camera, none of the assumptions could be explained or reproduced (imo) to match the unusual artifacts from that movie.
Do you mind to have a look at it and give us your opinion, please?
I am asking you as an expert with DVX, HVX being confident you should be able to see and identify the cause or at least point out what "can not be" out of all speculations.
Regards,
Dan Diaconu.

I took a brief look at it, and I don't know exactly what it is either. I would initially have thought it had something to do with the adapter, because the flickering pattern seems to be somewhat round in shape, but it being a beta G35 would lend me to think that the adapter would have little or nothing to do with it. A static adapter wouldn't have a rotating ground glass, although a static adapter stopped down too far would cause the 'hot spot' syndrome of the center of the frame being brighter and the edges being darker in a circular pattern (not "vignetting" per se, as that's usually the frame actually being cut off, but this is related to vignetting). And we're definitely seeing that here.

But why should it flicker? Three potential scenarios suggest themselves:

1) it's the famous Premiere 1.5 flickering highlights bug? Did he use Premiere?

2) it could maybe be related to slowing down the footage for slow-mo, if data was leaping from one field to the other, but frankly that shouldn't happen on a white wall. Unless, as has been suggested, that it's due to the grain being visible on the edges of the adapter, and it's the grain that's leaping from field to field, causing the perception of flicker? But I doubt it.

3) My guess would be that if it's not caused by Premiere 1.5, then he had auto knee on. The auto knee can cause exactly this type of flickering on highlights, and a white wall would qualify.

This assumes that he's using a 50Hz camera with appropriate 50Hz lights; if he shot with 60Hz lights and a 50Hz camera, and then slowed that footage down by 50% in post, that could cause a similar circumstance, but I would assume from his general expertise that he wouldn't have committed such an obvious mistake. Whereas the auto knee is biting people left and right, and it's hidden in the menus so I expect that it's the more likely culprit.
