Anybody know if the Sony F350/F355 variable frame rates will work on the Flash XDR? I suppose it depends upon what comes out of the HDSDI, and if the VFR are made as they are laid to tape then maybe they won't?
Cheers,
Steve

Dear Steve,

I agree with your assessment.

Since the Flash XDR will be able to do time-lapse recording (in I-Frame Only modes), it will be interesting to see if this will be useful to generate certain frame rates by dropping the undesired frames.

I have read the following in a review of the F350: "Variable frame rate settings above 30p halve the bitrate in HQ mode."

The above makes sense to me, in that if you have more frames of data that are being recorded to tape, and a fixed maximum variable bit rate for Long-GOP recordings, then something will have to give in order to capture the higher frame rate.

But, we will have to determine what is output on the HD-SDI port for frame rates above 30p.

Once we get a Flash XDR and a F350/F355 in the same room, we should be able to tell fairly quickly.
