  SLO MO (60p) straight from camera by SDI possible?

  Posted by Phillip Powell on January 5, 2006 at 6:32 pm

  G4 DP 1.25, FCP 4.5, 1 Terrabite SATA Raid, Panasonic Varicam. DeckLink Extreme.

  What I need to do: Have to slow down considerably a product in action.
  Thinking of shooting 60fps Progressive w/shutter speed, then slowing down to about 33% of normal.

  Best way in?

  I’m usually component in from BetaSP, or DV fire wire. Is possible to go direct from camera SDI in?

  Hoping some way can do from camera as I’m just testing at this point to
  see if this is gonna work.

  Ideas?

  Thanks.

  I’m not familiar with your Decklink capture card, but I know you could capture directly to FCP (5.0.4) from the camera HD-SDI spigot in the DVPRO100 codec with the Kona 2 (or LHe). By mistake I captured a 60fps tape with a 24p setting and it came in in slo-mo!

  I don’t understand your 33% though; if you’re capturing to a 24p project it will be slowed down by a ratio of 2.5; to a 30fps project, by a factor of 2 (100%) Obviously you can adjust the ratio by changing the frame rate.

  Furthermore you’ll have to convert the HD 24p (or 30p) slo-mo to a SD format; export it and render it out? Play it out as downconvert and re-record it (so you have a SD on-line master)?

  Hope this helps, if not you might try the FCP Forum.

  It is my understanding that the Decklink cards do not allow you to capture the offspeed content correctly in uncompressed via HDSDI. Only the Kona / Xena cards from AJA do this to my knowledge.

  Decklink HD cards do capture Varicam and the recognise the tagged frames.
  But, FCP has a problem while you are ingesting the off-speed shots.
  If you MARK IN/MARK OUT, FCP assumes this is the duration of the final clip – after it has been slowed down!
  For example, if you are shooting 50fps for half speed slo-motion, (I am in 50Hz country), then you need to MARK IN/MARK OUT double the duration you require, e.g. you want 10 secs of slo-motion (shoot 500 frames), you have to tell FCP to capture 20secs of material!
  What some people do is to record 15 mins approx on a 32 minute tape, and record black for the rest of the tape. Then ingest the whole tape to FCP via Capture card in one go.
  In 50z world the FCP FRC plug-in does not work. The FRC plug-in only works in 23.98/59.94.
  Alternatively us the Panasonic Frame Rate Converter Box.

  not in my experience with my kona / fcp setup, you set the in and out points and capture. Because the finished clip can be longer or shorter depending on the given frame rate.(more frames or less frames based on a 23.98 timebase)

  [Gerry Brooks] “In 50z world the FCP FRC plug-in does not work. The FRC plug-in only works in 23.98/59.94.”
  Yes, I do know that is correct. it does not work well over FW either.
