GoPro 1080i mp4 Issues

[Jean Le breton]

ok if I understand what you explain, there are no difference if I let attributes as “bottom field first” for convert my film the result will be the same of progressive

A friend of me try to avid media composer and the same result the attributes are “bottom field first”

the only for the moment I have found is to change in compressor the native footage attributes to “progressive” and after that in finalcut the video parameter as no frame

This is a matter of how the applications identify the footage.
But this is an issue for you to address because YOU know that the footage is Progressive.
I would recomend you to use MPGStreamclip.
Make a plain transcoding keeping all the original setting but the codec (Prores).
In MPGStreamclip, treat the stuff as Progressive.
Conform your p30 to p29,97 with CinemaTools.

hi!
I try with mpegstreamclip but when you import your footage you will see in field dominance “upper field first” and you can not select progressive only lower field first another thing as you can see in gopro web site the interlaced scaling is select in mpegstreamclip

just i can say now for the moment I don’t see any difference if I let setting “upper field first” or progressive with compressor”
