    Exporting clips

    Hey guys!  I have an old project that was recorded on DV tape.  I recently opened it up in media composer and it opens perfectly after 15 years!  That is truly amazing!  I think all footage was saved as .OMF

    Here is what I want to do:

    I would like to export all of the footage out avid in a lossless format.  There is quite a bit of clips.

    I have tried two different methods.  One was exporting quicktime same as source.  It seems to export lossless but I am not sure.  For some reason it looked deinterlaced.  Does quicktime deinterlace content. The other method was to export an AAF file.  I transcoded the media to DV25 in order to get the clips out.  This footage was all interlaced.   

    Any ideas on how to export?

    What do you need to do with the media outside of Media Composer?

    The content is already 5:1 compressed as DV so it makes sense to keep it as DV.

    You can export as an MXF op1a and select DV

    Re: Exporting clips

    I was going to color grade footage in resolve.  I also want to preserve all the clips to edit further down the road.  Is there a difference in quicktime same as source vs MXF op1a?  Thank you for all your help :-)

    Your content is already in DV codec. As long as you stay in DV codec nothing changes quaklity wise. The wrapper being Mov or MXF is just a wrapper for convienece.

    Not sure what Resolve will do with interlaced DV SD footage. Good luck. I'd test a few clips with movement and see what you get.

    Re: Exporting clips

    For some reason the interlace is only noticable if I export as an aaf and transcode to DV 25.  MKV and mov the interlace is unnoticeable.  I wonder if it is deinterlacing somewhere in the chain.

    Re: Exporting clips

    Are you sure you aren't scaling the image on playback? 

    Why are you transcosding to DV25? Isn't already DV25?

    But yes you need to be certain the interlacing is being retained or that you are de-interlacing correctly if you are happy to then have progressive clips.

    Re: Exporting clips

    I was transcoded to DV25 because it wouldn't play the footage in the AAF file.  I think I am abanoning that route and sticking to an EDL.

    Is there a way to output the 29i footage as 24p?  What would be the best way to do this?

    Re: Exporting clips

    You would need to bring those bins into a 24P project and then MC would framerate convert them.

    But I'd be wary doing that at this stage as you can't change it later.

    I'd keep the 29.97i and change frame rates later if needed.

    Re: Exporting clips

    I was just thinking of doing the deinterlacing before upconverting and grading.  I'll keep a copy of the 30i fooage as well.  Could I bring the exported  footage into another session?

    So it would be 720x480 30i to 24p -->upconvert to 4k ---> grade ---> export to youtube.

    Thank you again for all your help.  Your helping save a 15 year old project :-)
