GoPro Hero 6 H.265 (HEVC) Choppy Playback in Premiere Pro
on Mar 9, 2018 at 3:34:39 pm

Hey guys,

I have about an hour worth of Hero 6 footage from my Maui trip. It was shot in 4K 60 FPS, which uses the H.265 (HEVC) codec. The playback seems to be somewhat choppy, even though I have the Preview window set to 1/8 resolution. My computer is no slouch either (although it was primarily built as a gaming computer about 2 1/2 years ago, which was before I got into editing). In case it may be helpful - here is a list of my computer hardware: https://pcpartpicker.com/b/bcnnTW

What should I be doing to make the playback smoother? Should I just use Handbrake to convert all the footage to the H.264 codec before I begin editing the footage?

Thanks.

"My computer is no slouch either...."

Do you use an Intel Core i5-6600K 3.5GHz Quad-Core CPU for GoPro 4K 60 FPS H.265 (HEVC)?

Good luck !

Don't convert to H264 because it too is a format that requires heavy lifting by your CPU. Before starting an edit, convert all h265 and h264 to an edit friendly codec like pro-res or DNxHD and that'll eliminate the laggy playback issue.

Thanks - did some research and I am going to use proxys - seems to be the easiest way to go about it.

Proxies aren't appropriate in this instance. Your originating files aren't worth going back to for mastering.

Transcode all of the H265 and H264 to pro-res or DNxHD and then use those as your master files.

ProRes would be for Mac, so I should likely use DNxHD for PC right?

correct, dnxhd is the equivalent of pro res on pc.

What are your thoughts on Cineform vs. DNxHD? I guess the only downside of transcoding vs. using the proxies is that the transcoded files will be BIG and take up a lot of storage space.

Others here on this forum speak highly of Cineform so i kjnow that's an option as well.

Storage space shouldn't be an issue since the cost of storage these days is cheap. Buy more storage if you're short on it.

The purpose of proxies is to make it possible to smoothly edit high quality (i.e., 4k) footage on a computer that doesn’t have enough power to easily work with the originals. The proxy workflow allows you to build your video with the proxies but to do your final mastering with the high quality original files.

In situations involving h264 or h265 master files, there’s no need to go back to those originating files after transcoding them to an edit friendly codec so therefore the proxy workflow isn’t necessary.

Do not know if changes have been made to GoPro Hero 6 H.265 and Gopro Studio!

Many times, when I shoot with my GoPro Hero 4 Black - I take the footage into GoPro Studio - starts the first trim of the recordings - remove fish eyes and saves the recordings like Cineform intermediate .avi or .mov!

That's fine, but why transcode them to an edit friendly codec in the first place and not use proxies instead?

H264 and H265 files are CPU intensive and therefore I would advocate to always transcode them to pro-res or DNxHD before editing. It’s a one step process with no need to round trip as with proxies.

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.

It's probably a matter of defining "better workflow"!

It also depends on what the recordings will ultimately be used for!

Can you tell why you think proxies are a better workflow?

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.

Yes, with your "better workflow" you need to make color correction with the original H.265 before export!

"Transcoding it to a high quality file - DNxHR HQX UHD resulted in a 728 mbs file."

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.

[Yair Bartal] "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 the cost of storage being ridiculously low, the size of transcoded files shouldn't be an issue.

DNxHD and Pro-res are file types that work natively with Premiere and therefore even if you have a lesser computer they will play back just fine.

Using proxies for H264 or H265 files defeats the purpose of streamlining your edit since if you went back to the H264/H265 files for mastering you'd be right back where you started with CPU intensive files.

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... :)

Okay, GoPro owns Cineform codec!

So why not use: GoPro Cineform YUV 10bit, quality High
UHD 3840x2160, overall bit rate: 235Mb / s

"You can not compare apples to tomatoes."

Hmm, maybe you think I do not know anything about video editing etc?

"So why not use: GoPro Cineform YUV 10bit, quality High
UHD 3840x2160, 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.

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.

Couldn't you just render out a DNxHD file at the end though? You don't use all the footage you shoot, so why not just make proxies on the front end and then render out a master DNxHD file at the end?

I see what your saying though. It probably is not much more work to just trasncode to Cineform or DNxHD at the front end even if you don't use all the footage. Probably what I will do from now on.

So I transcoded about 300 clips from my Maui trip to Cineform YUV 10 bit. 690GB! Holy cow...how are people handling that much data? This has become pretty overwhelming. Just not sure how to handle data sizes that big.

Revisiting this thread...I had over 300+ clips (between 5-15 seconds) - transcoded to Cineform it was ~600GB. This just isn't practical. If every Premiere Project I have is 600GB, there is no way I can store that much data long term. So in this case I just don't see any other way of doing it other than using proxies.

[Carlen Cyphers] "If every Premiere Project I have is 600GB, there is no way I can store that much data long term."

A 1TB USB3 hard drive costs $60. So you can have your main MEDIA drive that you put the media on while working...a nice fast one, but then when you need to "archive," get the $60 drive....bill it to the client as "storage." Done. Storage is cheap.
