‘copy’ AVCHD files (mts files in a folder structure) will copy (including video and audio) and not transcode.

Thanks Jon.
Deliverable will be H264 1080p -
BTW, I’ve just tested the same clip with GoPro Cineform YUV 10bit and with the default quality value of 4 (maximum is 5) and the bit rate turned out to be 455 mbs.

“So why not use: GoPro Cineform YUV 10bit, quality High
UHD 3840×2160, overall bit rate: 235Mb / s”That’s still about four times the bit rate of the proxies, but it’s not the point.
The point is that one should consider all relevant info and decide for himself based on the relative ease of editing vs exporting.
The proxies workflow is better for me.“Hmm, maybe you think I do not know anything about video editing etc?”
Well, I do not know what you know and vice versa and if you were insulted I apologize.

Well, it’s up to the OP (and anyone else) to decide if the cost of FAST storage is ridiculously low for him, if HIS lesser computer can cope with high bit rate files and if he would rather struggle during editing with his lesser computer or export with the originals overnight or during the weekend (if that’s practical).
The bottom line I guess is: to each his own… 🙂

“Why do you want to transcode to DNxHR HQX UHD, with GoPro 6, which is recorded with 78Mbit for Protune? Is it not overkill?”
You can’t compare apples to tomatoes.
That GoPro 6 file is highly compressed and that’s why it’s only 78 mbs.
It’s always a question if you prefer a highly compressed file which taxes your CPU or a high bit rate file which taxes your disks.With proxies you avoid both.

Well, I’ve just made a test on a 20 sec UHD H264 clip using PP 2017.1.2:
– Transcoding it to a high quality file – DNxHR HQX UHD resulted in a 728 mbs file.
– Making a proxy file – Cineform 720P resulted in 69 mbs file.It seems to me that a slow computer can cope better with the proxies workflow.
Having said that, I’ve been told that proxies are not reliable for color correction, so… one has to decide.
-
Well, if one has a slow computer, proxies would still be lighter to edit than high quality files, and at the end one just exports with the originals. I think it’s a better workflow, but that’s me.
-
That’s fine, but why transcode them to an edit friendly codec in the first place and not use proxies instead?
-
I wonder why proxies aren’t appropriate in this instance.
Could you elaborate?
