    Video changing its framerates at random.


      Hi, I have a video that I'm trying to do a project with. However, the person that sent me the video is kinda noobish and I am unsure as to how it has been encoded and what not.


      The file itself is in mpeg format and seems to have been captured from an older dv camera. The person who sent me this video said the filesize was 9gb which is too huge to be sent over the internet realistically (which sucks).


      Video #0
      Codec :MPEG-2 Video
      Codec profile :Main@Main
      Codec settings/Matrix :Standard
      PlayTime :9mn 13s
      Bit rate :2600 Kbps
      Bit rate mode :CBR
      Width :720 pixels
      Height :480 pixels
      Aspect ratio :4/3
      Frame rate :29.970 fps
      Standard :NTSC
      Chroma :4:2:0
      Interlacement :Progressive
      Bits/(Pixel*Frame) :0.251


      These are the details given to me by the multimedia reporter inside of super video encoder (my go to tool basically). When I put this video into adobe premiere pro cs3, and add it to the timeline, and then preview the video file, it is VERY shifty, there will be small amounts of time when the video will play normally, but then it seems it will slow down and then speed up sorta to catch up to where it was when it slowed down, and then repeat the process again and again.

      I used one of the default templates for video. The video project details I have is normal widescreen dv @ 48khz audio (29.97 fps I believe). The video entails the use of four videos and a single audio track, and while the other videos seem to play with almost 0% problems, this video continues to irke my ire.


      The odd thing is that when I play the file in media player classic, the video is as smooth as butter. So I'm guessing it must be something within premiere or some setting that I am unsure of how to modify. Any helpful ideas are more than welcome as I'm just a hapless noob myself when it comes to video editing.

          Make your project settings accordently to the footage.

          You can do this via Desktop and set the fields to NON.

          Or convert the file to a dv-avi.

          Or download the MPEG plugin for Premiere from Mainconcept, this will edit the file flawless but you will be probably stuck with a watermark.

            Your client has given you an end product - MPEG video.  Rather than try and use a finished product as source media, your best bet is to get the original DV files to work with.

              I agree with both Ann and Jim.


              The best solution would be for the client to go back a level in the process, and get you the DV-AVI Type II file, that was Captured from the miniDV tape - not a processed MPEG. Note: file size will be larger still, but if he/she uses a site like YouSendIt, you can basically download the file. It's like FTP, but without having to possess your own server. Works perfectly. There are also many similar services that get around the large file sizes.


              Next, as Ann says, "convert to DV-AVI Type II." However, this means that the quality will already have suffered with the initial MPEG-2 compression. Super, or any other program, will not be able to put that quality back in. It is gone forever. Also, if you are going to output to DVD, or some other compressed format, you WILL induce another quality loss. The conversion to DV-AVI Type II is only so that PrPro can edit the footage most effectively. I would guess that your issues stem from using MPEG-2 files.


              I do not use Super, but it does get good recs on many boards. I was under the impression (seems mistaken) that it was limited to output PAL footage. It seems that I am totaly incorrect in that thinking, as you are outputting NTSC 4:3, right?


              Good luck,
