GoPro 1080i mp4 Issues

[Jason Brown]

surely you aren’t editing in the h264 codec? I use this camera all the time…I transcode to ProRes Proxy, then edit.

Also, you are saying 1080i…but the gopro doesn’t shoot interlaced…it’s progressive (I believe it’s Psf)

(check out this video I shot of my kids with the GoPro)

The reason I said 1080i is because when I bring the raw GoPro footage into FCP, the sequence settings automatically change to 1080i. Also it has upper field dominance and I was under the impression that progressive video does not have a field dominance at all.

I’m not editing with H.264. I’m still trying to figure out proper settings to make the video play smooth in quicktime OR FCP.

[Dave LaRonde] “Change the field order (incorrectly referred to as “field dominance”) of your FCP edit timeline to None. “
And also check all the stuff as NONE in the Browser.

[Steve Clay] “when I bring the raw GoPro footage into FCP, the sequence settings automatically change to 1080i.” First off, 1080i is the frame size, and it’s a bit antiquated language…check the setting below that that says “field dominance”. That should say “none”

And, this may just be my workflow…but FCP isn’t a program that is going to read this kind of information from a compressed video file very accurately.

If you transcode the footage through compressor, you can do a “pass-through” of all these settings. (frame size, frame rate, field dominance) if you just set compressor to transcode to ProRes (I use proxy because the bit rate is close to the source bitrate) and do a “same as source” on all the aforementioned parameters…that will give you an accurate “editable” file to take into FCP and have the sequence match.

thank for your quickly reply

I test your setting

but I have another question when I import my footage to compressor I get in the A/V attributs windows native field : upper field first I don’t know why if the footage of gopro is progressive I must get this information

have you the same thing

sorry for my english and thank you for your help

[Jean Le Breton] “but I have another question when I import my footage to compressor I get in the A/V attributs windows native field : upper field first I don’t know why if the footage of gopro is progressive I must get this information “

I hadn’t ever taken a look at this, but I just did and some 1920 footage I shot awhile ago came in the AV attributes as “bottom field first” — which doesn’t even make sense, because HD is UFF.

Either way, the gopro footage ISN’T interlaced…so it’s a moot point. If you set field dominance on footage that doesn’t have fields…it doesn’t do anything.

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.

I don’t see much convenient changing the Time-base while having the “Frame Control: OFF”.
