Hi,

Has any one run a BL2 at 50 fps?

What is the registration like at 50fps?

Thanks

I once did. Image steadiness was rocksolid. But you have to be careful. These are old cameras. The BL2 was built from 1975 to 1980, so the one you're shooting with will at least be 26 years old. No problem, if it was maintained well during these years.
Do you have a chance to do a steadytest before shooting?

I did a test at 24fps, and it was perfect.

The camera has been very well maintained over the years by a DOP who had it serviced at Arri NY. He sent me the last service records when I bought it off him, they did some work on it.

Today in Toronto another senior camera tech looked it over and did some tweeking, he thought every thing looked to be in top shape.

I could do another reg test at 50 fps to be sure, but it just means more time more money and I have to rent the speed controller as I don't have one.

The 50 fps will be needed for 3-4 shots on this job. I know higher speeds put more wear on the movement of any camera at any age.

Thanks for the info.

Richard,

I am sure it will be perfect. Its a pin registered movement. The BL1's went to 100fps, so the gate is overengineered. The advance has only 2 claws and not 4 for lower noise level. If the film runs and takes up work I would be 99% happy.

If its a $50,000 shoot then you need to test ideally with the same stock you will use for the shoot. A high speed scratch test makes sense in any event.
