Of course the same applies going from 50i to 50P anyway. So it is the motion to me that is more important to how the video will look. Going from progressive to interlace is not such a big issue. I shoot and edit 60P but put the exported HQX file in an interlace project to encode for Bluray.
    Sorry, thought you were correcting something, my bad.
    Yes the change between 25p to 50i will not have the motion blur as you get from original 50i.
    That is why I shoot everything in 50p for interlaced projects because then I have the option getting good interlaced quality, separate frame for both fields and the option to make progressive versions for other platforms.

    True.
    I know the difference between p and I, my point was you can only change project between p í in same framerate.

    things have improved with EDIUS 9.54 and X

    let me explain:

    I had to shoot several dance concerts and had to screen them at the cinema with one person per 4 seats, because of no audience allowed at the concert due to Covid

    most I shot at 25p and then I added the footage to 24p project bin and changed clip frame rate of all clips to 24 in one hit prior to adding to timeline timeline, then export to Prores 4:2:2 HQ and open this file in DCP-o-Matic to make the Cinema package and it looked superb at the cinema

    but I had to do two concerts where they also besides cinema ordered 300+ DVD so I decided to shoot at 50i for the sake of DVD quality

    I then added the 50i clips to the bin of a 24p project and set all clips to 24 fps in the bin prior to adding to timeline, but I left them at upper field. Then export to Prores 4:2:2 HQ and open this file in DCP-o-Matic to make the Cinema package and it looked superb at the cinema, I was very surprised, could not tell that it was shot interlaced at all

    50i is 25 fps (50 interlaced fields) so you can switch to progressive 25fps, not progressive 50 fps.

    Short answer you cannot switch between interlace and progressive in EDIUS. You can use interlace or progressive in either project type but cannot switch. Of the NLE's I have Vegas is the only one that can switch between interlace and progressive project while editing. Like Ulyssesvideo I shoot everything progressive 60P that gives all the options for project type and outputs. It is not a matter of multiplying time codes either. Interlace is fields and progressive is frames. It is easy to get interlace from a progressive frame but not so easy to get progressive from an interlaced file as the missing fields have to be interpolated to maintain correct temporal motion. If your main source is interlace then use interlace project and just put the progressive GoPro video on the timeline. It will work just fine. However if you want to use the interlace video on a progressive project it would be better to deinterlace outside EDIUS.

    i edit in a hd timelime... 25f either with 50p or 50i footage. I use edius 7 still.
    I produce tv ads for I film in 50p. give me the best look when I edit in an interlaced project file as it looks like video. been doing it for years.. no issues!
    if you create graphics... you will have to 2 it twice.. one in an interlaced project setting and in a progressive project setting.
    I do most of my titles in after effects so I will need to create 2 version.. interlaced and progressive. make sure when you apply it to the timeline that it is one or the other.
    when u export.. you can either select either project setting.

    Does anybody know how to change 50i project to 50p ?
    Can Edius X do that?


    When Im editing for TV - I need interlaced project 50i. Some pro cameras cant work in 50p .
    For PC or Youtube - 50p project looks much better especilally in grafics and progresive pictures.

    Even if I export 50i project to 50p video grafics and titles jitter up and down.

    Sometimes I need to mix 50i footage with 50p from gopro.

    So Its why - I need to switch between interlace and prograssive.

    I didnt find any way to change project frame rate so far.
    - Importing sequence doesnt work.
    - Importing EDL, importong BIN ..... ALL IS BLOCKED because of different framerate.

    But from my point of view it should be very simple - Its only about multiplying or dividing by the timecodes 2


    The only way that works is: Write down the Timecodes and edit the film again ....... In 21 century.
Working...
