  Problem Exporting at Correct Framerate

  Posted by Paul Walsh on January 22, 2014 at 5:16 pm

  Hi everyone, long time listener, first time caller here. After trawling through the forum as I usually do whenever I have a problem, in this case I have not been able to find any suitable solution to the problem I’ve been having.

  I have to produce short video reports to required specifications:

  MPEG-2 (or MPEG-4 AVC or part 10, i.e H.264 in Final Cut Pro), PAL, 6000 kbps CBR, 25 fps, interlaced, 1-st field is lower, HD (1920x1080i) or SD (720x576i).

  So, one of these specs is that we export at 25fps. Now, I’ve been shooting from a JVC GY HM-150 camera with the ‘System Select’ at 1080-50/25, then in ‘Record Settings’ I have it set to 1920/25p (because trying it at 1920/50i it did not seem to be really recording at 1920×1080).

  Now, when I import this into Premiere it reads it as 25fps, and then I export it at 25fps too. HOWEVER, when I open the video it VLC media player and look at the codec settings, it tells me it is running at 50fps. I can’t send the video at 50fps and I can’t for the life of me work out how to get it to export at 25fps, despite trying a bidillion different export settings. Any ideas? If you need any more info, just holler.

  Cheers,
  Paul.

  25fps interlaced is usually called 50i and maybe that’s why it shows you that. If you bring it back to Premiere and it says 25fps LFF you should be good to go.

  Hi, sorry for the late reply. I was in a bar in the middle of nowhere writing that last message through desperation while out shooting so couldn’t respond at the time.

  You were right though, the video was actually 25fps but VLC was saying it was 50, which really got me worried for a while.

  Thanks for your help.

  Ah, I guess it is Lower Field First, right?
