Title: 5 sec WAV Audio in RAW
Post by: fatpig on June 22, 2013, 12:22:55 AM
Hello guys,

I posted this over in Raw Forum already, feel free to clean up there.

I just read a post on here which gave me an Idea:
since the WAV recording is not continuous and it sometimes stops the recording of .RAW Video, too-

why not implement a mode to record a predefined number of seconds of WAV Audio along the Video when pressing record,
to give users a base to start with, using software like pluraleyes to sync audio automatically.

This could save hours in post-production and may only require a little coding.

Anyone up to the task?

Sweet Idea,

i know u can clap your hands and things... but if your filming nature you dont want to scare it :)

it is all about less man-hours in post.

if this feature were implemented,
we would just say scene and take number at the beginning-
or make any other distinguishable sound/noise.
Then:

- import RAW with WAV in the editor timeline
- let pluraleyes work out the syncing of the rest. Easy.

So syncing Audio will take 5 minutes again, instead of several hours.

Advantage over sync beep: can not mistake one take for the other. :)

can canon dslr's generate smpte timecode?  I am not a movie maker at all but I know I see smpte in the ableton settings menu and it allows you to sync audio to video from what I understand.

well, where would you put in your timecode to make it sync in the first place?
also, your audio recorder would have to have the same timecode-

AND you can be sure that these timecodes will start to differ after some hours..

We'd just need an option to make the WAV stop by itself before it kills our .RAW recording buffer, so we can still keep filming without sound :)

Is it even possible to merge audio into the rawfile to begin with?
