I think the answer to this problem is indicated in the original post and eluded to in some of the responses.

The original post states his source timebase is 23.98 and “assumed” sequence timebase is 23.98 but then says his sequence ends at 01:46:06:29.

You can’t have an end frame at :29 (frame 29) if your timebase only goes between 0-23.

The sequence timebase does not match the source material.

Mr. Zelin,

You are correct, and I most humbly apologize for my error. Yes, dBm does refer to milliwatts into a 600 ohm impedance. I should have specified +4dBu as equaling 1.228 Vrms.

I’ll stick with direct communication with AJA concerning why they only permit attenuation and won’t add the ability to boost analog inputs over unity when deselecting “Lock Input Audio Gain”

Thanks for your time.

Bob,

Thanks for your response.

I have no intention of using the FCP meters to set volume levels.
I agree their best use is just to indicate the presence of audio. My main comment was;

If I capture a clip with the default (and maximum) of -20dB referenced to +4dBm tone, the result is a relatively small amplitude waveform with a huge amount of headroom.

and

I’d really like to be able to raise the incoming level to be equal to FCPs default -12 dBFS without external amplification.

Also, I refer to +4dBm as the current standard since the industry no longer requires a 600 ohm termination in inputs.

So, why couldn’t AJA rewrite the drivers to allow a wider range of input levels (even as the analog world fades away)?

A big thank you to John & JR.

John’s information directed me to the right area of the manual for further information.

Indeed Photo-JPEG is used as an RT Extreme codec but after some trial & error I determined it’s only “RT Extreme” compatible when set to 320×240 which looks terrible.

So if I want to utilize the Open Format capabilities of FCP6, I’ll use DV for library archives, ProRes (NTSC) for most On-Line and Photo-JPEG (at 320×240) for long program off-lines.

The pop-up will only occur if there is no video in the timeline – and the clip doesn’t match the timeline settings. Once you place the first clip in the timeline, FCP assumes you know that you are now mixing formats and never asks again.
