I just did a project with an SR3 syncing audio manually using the clapper alone. What a pain. I know the SR3 is timecode capable but I just haven't used that work flow. I'm looking into that in the future. How pleasant it would be to have the transfer house do the audio syncing for me in a standard "dailies" model.
Yes, Will! OP do not take any of the encouraging advice to go ahead with a Arri SB project with non-synced dialogue on Steenbeck!! Haha, I'm not even going into the details as to why, because it's so stupid and it hurts my head to think about it.
But this- you will never finish your project.
It will be an exercise in frustration, time wasted..etc. attaining useless skills such as syncing mag or working on a flatbed.
Repeat this to yourself in times of weakness- "There is no glory in making already difficult film production more difficult in the hopes of fulfilling my nostalgic fantasy that no one shares".
Do you think the editors of 50's wouldn't trade their flatbeds for a NLE system? Oh man, they would..They would kill for one. And you come along and blithely with the wrong camera attempt to create chaos!
You wanna shot sync? Get a sync camera (with a crystal motor and self-blimped) and stop **(obscenity removed)** around. Best advice you're gonna get!
**note: You'd prolly spend the same amount of money getting a special motor for that SB then just selling and buying a sync camera.
