  • 25P or 50i converted to 25p?

    Someone may know the answer to this. Is there any difference to the picture quality when shooting 25P as compared to shooting at 50i and then converting the clip to progressive in EDIUS? I would have thought that pans etc may come out smoother after the conversion to progressive (as compared to panning at 25P). Any thoughts on this?

    The problem is you will end up with a double image converting the 50i, as the two fields are combined into one frame and on a pan or movement there will be a difference in position between the two fields.
    If you use 25f this can be done with no problem.
    If someone has a good conversion post it

      I shoot mainly in 50i and produce 25p files from that footage for the web - I let Edius render and de-interlace; to be fair it does a good job.

        I take it you use WMV for the web and yes that seems to work reasonably well, but so far converting from "i" to "p" on the timeline or converting to HD or SD Mpeg gives me a double image frame
        I don't like the jitter of "p" and my normal output for TV or DVD requires "i" so that is what I film in.
        If my major concern was for the internet then I would film in "p"

        What settings do you use??

          yes I mainly create WMV files as these generally are quickest to render and offer a decent quality.

          I generally use between 6000-8000 kbs CBR for 1280x720 sized frames, no point creating files with 1920x1080 frames as all video sites seem to want 1280.

            Thanks Mattie
            That is around the same as I have used, I have tried H264 but the file always ends up too large and the WMV seems the best compromise for size and quality. Well from Edius anyway, just wondered what you had used

              yea i try all sorts too - most sites ask for h.264 but like u say wmv seems to work best from Edius


              maybe try a .MOV with h.264 encoding and set max bitrate to 3000 kbs

              you might be surprised :)

              (for a HD file)
