How about embedding a smart contract into the audio using digital watermarking?
Essentially, a trusted encrypted ledger entry could embed the date (or any particular information) such that later on you could retrieve the value and compare it against what is in the ledger.
Don't know if that's a thing, but it sounds like it could work.
This might be a forensics question, the answer to which is is the ENF signal (Electrical Network Frequency) which is used in forensics to locate certain associated acoustic and electrical signals in time for forensic purposes
ENF is a technique commonly used in audio forensics. It requires analysts to have recorded ENF signals over a long period of time.
Various places I've worked have found different solutions. Some record the LTC from a broadcast video tape to an unused track. Some will reuse a track from an earlier project. The first is slow (1:1), and both are inflexible. Hardware TC generators are flexible, but it's still real-time creation.
I offer a free 32-bit Windows utility that can generate an ...
If master is 120 it seems to automatically adjust to song after it finishes loading in arrangement
To purely determine the bpm of your track:
Put the song in session view, otherwise the song will skip around
Turn off warping and Play from a chosen loop start point
Tap tempo to get a rough estimate of song's average tempo
Usually if you just align the song ...
I'd say jam if you can. It really depends on what sort of thing you are shooting and how good slate discipline is on set! I think for your film you will be fine-and if you dont have the gear they cant expect it!
However, for future stuff the editor will really thank you for being able to sync up automatically without having to manually sync and on a huge ...
Not sure if this is what you mean, but just pressing the 'M' key will add a mark in your session while recording. Add as many marks as you like. Many different tools can use these marks for various things. The marks can be renamed if you like. You can jump from mark to mark.
I don't know of any sound formats that let you keep the marks as part of the sound ...
None of the Canon 5D series cameras will read incoming timecode. You can stripe it to one of the audio channels as a reference, but there is no camera timecode function as such.
Striping the timecode to camera audio will require your Video editing package to support LTC on audio tracks. I suspect that this is possible with Davinci Resolve.
I've only jammed Alexa from my 633 but there is a few steps you need to take when jamming any camera!
You probably want to make your 744 the master timecode source so make sure it is set up to send timecode-rather than receive.
You need to let the Alexa know you want it to be a timecode "slave" so you need to go into its menus an select "receive timecode" ...
