Kudos to Thomas for his location scouting. One additional detail: Thomas shall not be allowed to pay for any food and drink during this little get-together, right? The Layout King dines for free. Make it so. See y'all there, Adam Wilt Firewire drives - "Perry Mitchell" Firewire drives are an attractive proposition for storing and transporting DV files between systems. Is there any way you can do this cross-platform? i.e. record the files on a Mac and then use them on a PC? Perry Mitchell Fwd: White-balance problems with a PAL PD150? - Adam Wilt Kate Jones in the UK asks the following question: "We were shooting on the PD150, with a Sony Wide Angle lens attached and changed the white balance to suit the environment. However, looking back at the footage=A0we noticed that the camera was continuing to adjust the white balance even though it had been set to the 'hold' position. "The problem happened again the next day, shooting in the same = environment, however this time I noticed it on the lcd screen during filming. =A0 "There was an over head 'strobe' light close by, however if the white balance has been set to hold surely the camera shouldn't adjust it.=A0 = Have you heard of this problem before, or was it just my camera?" By "hold" she means, "having set the WB manually, and yes, the manual WB symbol was present in the viewfinder, so we hadn't put it back into auto-WB accidentally." I've never noticed this problem on my PD150, but given that the "auto shutter" is always active despite the menu settings (as Al Burokas discovered), I'm curious if anyone else has seen this? Let me know; I'll fwd the replies to Kate. Thanks Adam Wilt Synch issues with Sorenson V3? - Adam Wilt >> I wish my movies were just 2 frames off. But they are more like 15-30 >> frames >> off. And the amount of synch loss varies a little each time they are >> played... > > Would this be the difference between using drop frames vs non drop frames? No, there should be no sync problems attributable to compressing a clip with DF instead of NDF timecode. DF vs. NDF is only a difference in sequential frame numbering schemes for timekeeping purposes; the actual video and audio are the same in either case. [DF vs. NDF can cause problems in double-system production or in separate production of audio tracks for layback, but this is usually accompanied by inadvertent differences in the audio sampling rate, which only arise from improper communications amongst the people concerned in the first place!] Somewhat-related digression: Slipping, displaced, or variable sync seems to be a systemic problem in MPEG-2 sent over DTV to this day. Different receivers align the sound and pix from the same transport stream in different ways. The ATSC standards include timestamped markers that are supposed to keep the sound and pix in sync, but apparently these time stamps are subject to interpretation. I'm not sure if our Euro friends are having equally fun times with DVB, but I suggest that the simplest fix may simply be to relax our absurd expectations that sound and image align on frame boundaries. With DTV we should be happy if the sound and pix are in the same ROOM, never mind on the same frame! Syncopation and slipping the beat are the very heart of jazz; get jazzy about your video, and all those annoying sync problems just float away... of course it does help to drink an entire bottle of cough syrup first.

I was simply getting snippy with the Reverend regarding SMPTE bar colors, because after all he's a SMPTE member, and if he isn't going to uphold the sanctity and purity of his own organization's colorbars, who will? :-) > (Shameless plug to follow): If you want to see this color of "yellow" > used for titles, check out "Tour Maui In Two Minutes" at the DVExpo Film > Fest.
