Sound recording in Native mode

[dglasgal]

Can anyone tell me their expierence in recording sound while shooting in native mode? If under or overcranking, then brining into FCP through frame converter, does the audio come in also?

thanks

Sound is only recorded at 30fps for 720/30PN for NTSC and 25fps for 720/25PN. All four tracks are silent for any under- or over- cranked speeds.

Right. If you're shooting native mode at overcrank/undercrank speeds, no sound is recorded on the card at all.

If you want sound and overcrank/undercrank, you must not use the native mode for those shots; use 720/24p mode and it'll record sound too.

Can I get good high speed/ slow motion effects with that mode?
Thanks!

If you want to record sound and under/over-crank, you'll need to record at 60fps and ramp using your NLE.

You can see an example of ramping in http://www.dvinfo.net/conf/showpost.php?p=447305&postcount=1

... that was recorded at 60fps and played back at various rates in software.

Unless I'm mistaken (always a good disclaimer, eh?) you can record any frame rate in "over 60p", and extract the right frames in post (using, e.g., Panasonic's free FCP frame-rate converter plugin). So you can indeed record any over-or under-crank, with sound, in non-native mode without any downside except a) using the full 100Mbps bandwidth/storage and b) having to toss the extra frames later (which I think is pretty painless given you already have to convert from MXF; I think it's done at the same time).
