MP 7,1 Can I use 4k60 H264 or H265 without proxy in FCPX?

[jccmaxon]

My new Mac Pro: 12 cores and 580x.
Actually, I can’t To Edit in 1080p H264 with several layers. Playback not is smooth. I need the best smoothness.

Now I use previus render option, however, I would like Edit 4k60 H264 or H265 very smoothness.

¿Is it possible without use proxy? Which gpu should i use?
I thinkt that my CPU is Ok, but I don’t know which gpu To use?
Thank you.

Maybe the Mac Pro 7.1 can't do it by using Xeons?

Update: haven't read the title correctly. 7,1 has HWAccel activated by default

Is it necessary in new Mac Pro 2019?

Which software you use for video editing?

Did you check if you config it properly to use HWAccel?

The timeline playback always laggy? Or only laggy after applying some demanding filters?

The 580X isn't that strong, but if my RX580 can edit and playback 4K 60FPS HEVC in FCPX timeline smoothly. I can't see why your 580X can't do that.

I edit in FCPX and my video is mp4 h264 1080p. Playback ok, but when I use several layer laggy. For example, look my video:

If that only happen after applying some filters, then I will assume the 580X isn't strong enough.

AFAIK, it's mainly the GPU's job to apply those filters in real time.

Do you have anything like a Vega64 on hand to test if that works better?

I will buy a Radeon VII (XfX model) in Amazon. I hope timeline smoothness.
Thank you.

Have you set timeline playback to 'better performance'?

What hard drive are you using to store all the video?

Yes. WD Thunderbolt Duo (never problem with my iMac late 2013)

Are you saying you can you playback this video smoothly on your imac 2013 using the WD thunderbolt duo?

Have you rendered the effects in the timeline?

I have an old 2009 mac pro all my video is stored on SSD inside the computer. I can run a multiclip of 6 streams of HD h264 without problem.

Im guessing the bottleneck is the WD thunderbolt drive or unrendered timeline.

without previus renderes was ok in my iMac late 2013. Same proyect and same wd I have this problems in playback with 580x. iMac Late 2013 780m i7 no problem with same wd. I have tried same proyecy on ssd and same problems.

¿What Gpu do you use? I hope that the solution be a new Radeon vii.

It's impossible the modern HDD can bottleneck normal bitrate 1080P H264 video's playback.

If you rendered the timeline, that's ProRes, not H264 anymore. ProRes need high speed storage, not H264.

What OP asking is to play H264 in timeline with applied effects directly without rendering. We have HWAccel nowadays, no need to spend time on transcoding / rendering just for timeline playback (if we have the required hardware / software).

The OP claims the same project plays back smoothly on his 2013 iMac, but his new MP7.1 cannot playback the timeline smoothly!

I looked at his example video on you tube and he is playing back several layers of video with effects and transparency at 147% resolution - unrendered.

He is also wanting to edit 4k60 H264 or H265 smoothly without using proxy.

This requires further investigation, there is a bottleneck somewhere.....?

How much RAM do you have in your Mac Pro?

what size monitor do you use?

In the playback window you have the zoom at 147% maybe make this 100% or less and see if it makes it smoother?

The 2013 iMac use QuickSync to hardware decode the H264 video on the timeline. And the 780m to render the effects. I won't be too surprised that the iMac can play un-rendered timeline smoothly.

For 7,1, we still not 100% sure, but most likely the 580X use AMD UVD to decode the timeline. The question now become if the 580X can do BOTH hardware decode and render the effects in realtime.

I understand that should not happen (the 2013 iMac works better than 2019 Mac Pro), and something is wrong. But the issue cannot be the hard drive (for direct H264 / HEVC editing).

Even USB 2.0 HDD can deliver 50MB/s, that's ~400,000kbps, extremely abnormal high bitrate for 1080P H264 videos. In general, 10000kbps already very high bitrate for 1080P H264 video, that means, only need 1.25MB/s storage performance for smooth playback. Therefore, it's very impossible that the storage is the bottleneck.

Thanks you for all. I have 32gb RAm but I only use 16gb more or less. No problem. I use a Tv 4k like monitor. ¿What gpu I must To buy To editing FCPX 4k60 h264 and playback smoothness? Thanks

I test it. Same problem. 100% or 30% it’s the same problem. I don’t know What Is it the problem?

WOW so the $5000 mac pro is worse than a 2013 imac!

h9826790 pointed out that the Intel process have quicksync to decode h264 the Xeon do not have this function so they need to use the GPU to decode.

Can you tell us what effects you are using in the timeline?

I noticed in the video the white dotted line above the timeline, try 'Render All' and see what happens????

I use this effects and two layers at the same time. No more. It is in this moment when I have the problem.
If a Render all no problem. All timeline smoothly. Perfect.
If I buy a Radeon VII, would have this problem?

Thanks you

What GPU I need to have a playback 4k60 perfect without pre-render all?

Why?
Apple created the 7.1 with a particular editing hardware, software, workflow in mind ~
Metal, Multicore CPU, Multiple GPU, Pro Res, Afterburner (to take load off GPU), FCPX Optimized for Metal. This is where your computer will shine.

Here You can see the complete problem. Editing 4k60 H264 without proxy IMPOSSIBLE! The same problem, but I have got to stop all in FCPX a lot. IS IT NORMAL?

How can I make it smoothly? Please

Why you not want to convert to ProRes and render on? This will take advantage of metal/fcpx attributes? Do you have afterburner card? I think your CPU is not strong enough. There is no problem editing 4k60 H264 with my configuration. Its normal workload for 7.1

What is your configuration? My CPU is 12 cores. when the problem occurs the CPU goes to 4ghz (it seems the maximum) although the total load of the CPU is ridiculous approx. 6%. I haven’t got afterburber. Thanks.

perhaps with a i9 o threadripper i could do it would be useful if I converted to prores, right?
