Clip length shortened by FCP 5 during capture!
Hmm, add this to the pile of FCP 5 complaints:
Wondering if anyone has been experiencing clip shortening when batch capturing in FCP 5.0. After 65 percent of my capture attempts, FCP has shaved up to 20 seconds off of the Media End as logged, thereby shortening clip length. I have scanned the last week of the cow and apple forums pretty thoroughly and haven’t found any similar reports.
This shortening has happened across a variety of scenarios: Digibeta source via Kona2/SD-SDI and AJA IO SD-SDI, as well as DVCAM via Firewire NTSC DV. It does not seem to have occurred capturing through Panasonic 1200A/Firewire to DVCProHD (though we were having frequent dropped frame issues).
Our equipment: 10 edit suites running FCP 5.0.2, OS 10.4.2, QT 7.0.1, Kona 1.1.2, and (in 5 of 8 suites) IO 2.0. All are dual 2gHz G5s, 2.5 GB RAM. 19.4TB Xserve RAID via Fibrechannel/Xsan 1.1.

Make sure that you have the latest drivers downloaded from the AJA site. The last 2 revisions have dealt with this issue as well as audio sync issues during batch capture.

Hi,
We capture many long clips on KONA 2 and BLACKMAGIC systems with similar consistent behaviour / problems. FCP completes the capture normally but the actual clips are shorter than that specified in capture. PAL here btw
I believe this problem has been escalated within Apple.

re. the audio loss.
We have never liked the way that you are allowed to control the input gain with a digtal input. We have definitely not liked the way the OS sound preferences also is allowed to control the gain on input and output.
Just our opinion. If the levels are low on our source material we are more than happy to do gain adjustment within FCP.Anyway, since FCP 5 came out even the KONA2 and FCP integration hasn’t really worked correctly for us. We have had a recent remedy and I can only suggest you contact AJA and talk about some beta drivers which have a check box, ‘ignore audio gain’ in the KONA Control panel.

Thanks, Matt. We’ve tried the Kona2 1.1.3b35 driver but I wasn’t aware of the “ignore audio gain” checkbox in the control panel, so I will definitely see if that helps with the uneven levels. Do you know what gain stage it’s ignoring, exactly? Is it designed to override audio input settings in System Prefs?
re: clip shortening and your comment “I believe this problem has been escalated within Apple,” can you elaborate?
