PTT: PAL getting back Frame23 > Frame 29???

OK, now this I find interesting - kinda . . . .

Working in PAL. PAL widescreen. 25fps.

Done this procedure a zillion times . . not really, but it feels like it sometimes . .

Anyways, I'm now PTT[PrintToTape]-ing the project. Not a problem with any of this .. going well.

BUT! - You know when you PTT and you get a menu appear when you can use Device Control, that tells you just where on the tape in the device you are: 00:01:20,05 = 1min 20secs and 5 frames. Well I spied just now a frame of 29!!! 29? Project is PAL=25fps. Media is 25fps. EVERYTHING I can tell is 25fps. What gives?

However, just for larfs I manually used my Deck frame <= => adjuster and guess what? Vegas does display in the PTT Device Control tape frame-position: frame 1, frame 2, frame 3 . . . frame 23, frame 29, frame 1.

It would "appear" that frame 24, the penultimate frame, prior to the next whole second, is displayed as "frame 29"!!

Now those with a more than just a modicum of DV programming sense than I ever will, I invite to postulate if this is having ANY effect on the rest of Vegas? Is this a bit of vestigial NTSC 29 frame code messing with the display? OR is it being "used" from something MORE important. Or is it just an unessary irritation and one I can ignore?

For those of you who have a similar PAL set up and use a deck .. maybe even a camera? . . may wish to get back with a "Grazie-reality-Check".

If we find this IS the case then I'll bung an email to Product Development.

TIA!!

Grazie

Thank you for your feedback, Leslie. But are saying:

"NO" = 1>24

or ..

"NO" = 25>28

or . .

"NO" = . . .

Or are you getting frame24 THEN frame1

I'm not getting 25/26/27/28/29 either! I'm getting 23/29!

Sorry please explain?

Is this blank tape in the VCR?
Or even a bit of blank tape?
And which PTT method are you using?

"Is this blank tape in the VCR?" No as in no picture?. Have laid down some "BLACK" T/C. That's why I CAN see a T/C? Yes?

"Or even a bit of blank tape?" Nope not blank - Black T/C

"And which PTT method are you using?" From Timeline. Not from within VidCap.

What does this tell you?

Regards,

Grazie

Not much, really don't have much of a clue.
I suspect like you this is a vestige of some NTSC thing that's not sorted out properly, guess if it's not causing any real issues it's unlikely to ever get sorted out properly.

Is your deck a PAL only deck or is it PAL / NTSC switchable, just wondering if it could also possibly be the deck.

i get 00>24 frames inclusive. no 29. but i'll give it another check tomorrow...

apologies again.

does the tape have the 29th frame recorded in tc?

You're ok Leslie - no worries .. however .


" . . . does the tape have the 29th frame recorded in tc?"


.. that just turned me around. What do you mean? T he code on the tape READS 0>24 as per you . . BUT in the Vegas Device Control it goes 23 > 29. Frame 24 is not displayed as being there.

Although Bob and I are of the uninformed opinion that this is a piece of vestigial NTSC programming, I'm more than a little curious to know if this IS a problem being stored for something further down the track - literally!

oh .. yes Bob, the deck displays on its own readout . . 23>24>0 . . This is, of course, communicated via the OUT and onto my JVC monitor display. - G
