Cassette Tape Recording sync with Video Issues

Are you simply looking for that "cheap cassette recorder sound"? Why not record with a proper recorder and then cheese it up to sound the way you want?

I can tell you that consumer cassette players, especially when using batteries, will MAYBE play back at the same speed and if you are recording on one machine and playing on another, you will have significant drift and you will have many edits to bring it back into time.

2nd suggestion is to come out of the headphone jack & into your mac and capture at the same framerate as your sequence.

Cassette machines (well tape of ANY kind) were NEVER capable of what we think of as "sync sound". Extraordinary (and expensive) means were taken to synchronize tape to film/video. Most of that technology doesn't even exist anymore because use of analog tape for production recording has essentially gone extinct on this planet.

You must choose between your "artistic choice" of using a cheap, primitive, antique recorder vs. synchronized sound. It is as simple as that.

Digital recording technology, in addition to being "cleaner" than analog, also has the advantage of being much more STABLE, making the need for gen-lock, time-code, etc. not as mandatory, especially for shorter (<10min) shots.

Yes, there are probably still people using Nagra reel-to-reel machines for sync recording, but that audio solution probably costs more than your camera. And, of course, there is no sync capability in your camera. And it doesn't sound like a cassette machine, either.

IMHO, your desire to use a cassette machine for sync production recording is simply not practical.
