  • 25p in FCP Question

    Posted by Tom Mooney on April 27, 2009 at 2:12 am

    We have a client that asked us to record an interview that needs to go to France in PAL. They requested the file be exported as DVCPro HD 25p and FTP the file. Our camera is a JVC 200 and it does record HDV 25p. I did a test and it imported into the system fine. I see a flicker in the viewfinder of the camera once it rebooted to 25p. I can also see the flicker on the monitor in FCP. Is the flicker a process of recording in PAL? Thanks in advance.

    Hi Tom,
    Record p24, then you only need to conform the files to p25 in CinemaTools.
    No rendering, no quality lost. Really fast process.
    Your p24 is read as p25. The film is speed up a 4%. Impossible that nobody notice the footage was shot at 24 instead of 25.

    I suspect the flicker is just a function of the lower frame rate and would also be apparent at 24P. My HVX-200 finder looks that way at 24P. I have shot 24P for European clients and they have done the conform in Cinema Tools or Compressor. Both 24P and 25P can be conformed from one to the other, making them good choices for dual-purpose use in the US and Europe. Your camera shoots both, so you’re able to choose the best for each situation. If the footage is only for use in France, the 25P is the way to go.

    Is the flicker coming from your lightsources? If you are shooting 25 fps in a country that uses 60Hz electricity you may have problems with the alternating current switching at a different rate than the camera shutter which results in flicker from any lightsource that is not ‘flicker free’.

    I used a JVC 250, recorded something in 24P, and then when I conformed 24p>25p in Cinema Tools, the footage came out in Slow Motion — sound and all. But when I dropped it into a 50P timeline it seemed fine. Does anyone have an explanation?

    Hi Ashley,
    The only possible explanation is that you by mistake recorded really p50.
    If the footage have only been conformed, there is not other explanation to end up with 50 frames per second.
