Problem with Transferred Video- Dirt, Hair?
Hi Everyone,
Thanks to everyone who helped with my frame rate issue. I saw my 2nd week of rushes last night, that were transferred to mini-DV by a telecine, I noticed a translucent white line across some of the spools that were processed. I’m not sure if this is the negative itself or whether it is just the result of a bad telecine. This line remains throughout entire shots, and then is at times not as noticeable or doesn’t show up.
If this isn’t a telecine problem, and the negative has this line, is there any way to fix this problem other than reshooting everything, which is my backup plan.
Thanks,
Steven -

Sounds a lot like a scratch. Could have happened in the camera, or in the telecine, or if your school loads spools themselves, could have been there.
Are you using reversal film or do you have a negative?

Is the line vertical or horizontal (as you describe it as “across some of the spools”) which implies horizontal.
If vertical then it sounds like a neg scratch. If horizontal it might be a telecine fault. You could get your lab to have a close look at the neg to see if it is on the film. Talk to your lab about techniques to remove neg scratches if it turns out to be this. A reshoot may not be neccessary

It’s a vertical line, translucent white (you can see the image through the line and it seems to fade depending on how dark or light the shot is), and I’m using negative film (double x 200/250 ASA Kodak 16mm Black and white). I have already instructed the lab to look at the negative to see if the line is existant on the negative.
Thanks,

Here is two examples of the line from the same reel.

Looks way too large and “soft” to be a scratch. Maybe a scuff from a roller, or maybe some odd light leak or other optical flaw.

Could be a base scratch, rather than an emulsion scratch, hence it is soft and out of focus. A close look under a magnifying glass at the lab will tell. If you have good location records, you should be able to tell if it is a faulty magazine. The fact that it is not on all rolls might point to a roller or guide fault in a particular magazine. In the old days, we used to write those details on camera sheets to find just these kind of faults.

I was shooting using a Bolex with 100 foot daylight spools, not magazines, if that changes anything.
