Help with developing time Kodak double x

I'm 90% sure that the flicker in this is a film, development problem.

Probably because the film is expired.

It could be light leaks but I think it would be more steady and also more on the edges of the film in that case.

I made 2 test shots with 2 different cameras.

The shutter repair on Bell Howell 240 did not make much different.

I tested a kiev 16UE and it have the same flicker.

I can see the flicker in the film that I shot and developed 10 years ago, but not as much as it is today. That was with a Canon Scoopic.

I will try with a 15 feet spool of orwo un54 when I have time.

Can it be worth to try with an other developer?

Now I don't mind grain as long as it is even exposed.

Don't think so. If it's related to the film, then it must have something to do with uneven fogging. Which is unlikely/uncommon, so no, I really don't think it's due to the film.

Without knowing that specific camera and little about movie cameras in general, I'll just say-

I've seen a lot of light leaks. Usually they do repeat at some regular pattern along the film, but exactly what that pattern is depends on where the leak is. If it's somewhere in a film chamber, especially in this case where presumably one rotation of the take-up spool accounts for several frames, you may see a "stripe" or some other artifact that repeats for every time the film winds around the spool.

In still photography, you might see something like this if you open the back of a 35mm camera without rewinding the film-the a few frames will be completely fogged, then you'll have increasingly narrower strips that might completely miss some frames or be right in the center of others.

In this case, I wonder if it's a minor enough leak that it's not fogging the film significantly while the camera is running, but will fog if in bright light for a few minutes. Without seeing the film path or knowing what seals are there to spot likely culprits, I don't want to speculate any more than that.

With that said, if you want to rule it out, after loading in as little light as possible, you can use electrical tape or gaffer's tape to tape over every possible place light could leak in the camera. If the light leaks go away doing this, you know it's a leak. You can start removing tape and seeing if it returns, or just proactively replace any foam or other seals that can deteriorate.
