I have about 2 years' worth of travel footage taken with a GoPro 9, recorded in 1920x1080 and 60 fps (well, 59.94 according to the files themselves), bitrate 45221. Codec for these settings is H.264+HEVC, and footage is saved as MP4. (I have not recorded anything in 4K)
Many of them will need color correction (not a fan of the GoPro color profiles, as I found out) and some videos will need a complete overdub (original audio track removed and replaced by an overdub that I will record in realtime during the editing process) because of lousy original audio.
My intention for the finished videos is twofold: (a) to ultimately burn them to Blu-Ray NTSC discs, for players (ideally, with at least two videos per disc, if they fit) in order to retain the best video quality; and also (b) to also archive each video on a portable external hard drive that can be plugged into any USB-A port and viewed that way also.
First question: I've read recently that GoPro footage isn't as amenable to editing as other codecs, and that it's better to convert the H.264 footage to something else at the outset. That said, the pages suggesting this were sites that happen to sell converter software, LOL. So that's my first question: In PD20, should I work with the GoPro footage as-is (native H.264)?
Second question: Assuming the editing all goes well, what encoding formats should I choose when I get to the Produce stage in PD?
If I choose MPEG-4 for burning to blu-ray, can the frame rate be 60 to match the video (and retain the 1920x1080)? If not, which blu-ray compatible format will do that?
I will also need to burn some to a DVD-R, because not everyone who will be getting a copy of the finished disc has a blu-ray player (and some don't even own a computer but they do have a dvd player connected to their tv). For those DVDs, I guess I will need to encode as MPEG-2 despite the resulting lower resolution. (for single-sided 4.7GB Verbatim DVD-R)
For the archived finished videos that I will store on a portable drive, what encoding format will also allow them to be viewed directly from that medium on any Windows computer?
Sorry for all the questions but considering that I am facing the prospect of having to create 18 different videos, all shot with the GoPro, I would love some suggestions as to the available Produce / Burn format choices that PD offers.
Thanks in advance!
