So playback in vegas of 60p footage plays at about 40-50fps...using 90-100% CPU. Opening same file in any media player uses 2%CPU.....So obviously my computer can play it back without issues without slightest stress or issues for the system.

Can you edit video with a media player?

no, but thats not the point, software i tried a year ago played back NX1 files no problem with no cpu usage.

“Problem is I MUST use Multicamera and having NX1 and GoPro footage makes it crawl at 1, yes ONE Frame per second...”

Proxy workflow or digital intermediate using Cineform, Magic YUV or XAVC-i.

that a big waste of time... Pretty sure would all benefit if files could use our hardware properly.

sorry but i asked if there is going to be an update to resolve this issue, using proxies when you have powerful hardware is just not good for 2018 and going into 2019... Other software can playback smooth as butter even scrubbing..... and again i've been using vegas for ever. and 16 is the first version for me that has yet to crash even with GPU ON......

Also i've been transcoding hevc to h264 and im always 1 frame short and video frames don't exactly line up with the original source.....the way i edit, i would like to be exact to the frame....

...sorry but i asked if there is going to be an update to resolve this issue...

Only Magix would know that and we're extremely unlikely to find out until such an update is released. So the answer to your original question, unless someone in the know tells us otherwise, is "Don't count on it in this version".

My comment was about making sure you've optimized other factors that may improve your playback performance, and helping you implement john_dennis' suggestion in case you didn't know how.

Im sorry i thought you were from Magix :) so the weird thing is maybe you can help is this. When i drop my Original go pro or NX1 or sony a6300 4k files and i go to the end of the file in timeline (quantize to frames is checked/on) the files extend like 1 1/2 frame past actual file length, and timeline bar doesn't align to the end of the video file. When i transcode my go pro, nx1 and a6300 files they actually render to the exact length of the file and timeline bar falls to the end of video file...... (so it seems transcoded files are a bit more correct for the timeline purposes)... But they also lose a bit of contrast/color saturation..... So weird.....

the reason why this is such a pain for me now days is cause i got gopro attached to my nx1, and when im running or need wide angle, gopro does it a lot better... thats why i need multicam editing now. but gosh i spent half a day today trying to transcode original nx1 and gopro fotage and unable to render it to the exact same length

Also original files of nx1 and gopro show proper frame rates when you click on a video and go to its properties in Vegas, after transcoding and dropping it into vegas Nx1 shows as 29.978 and gopro 7 as 59.949

Sooooooo annoying, any thoughts or ideas would be so helpful.

Im sorry i thought you were from Magix :)

You're not the first. It's unfortunate that Magix and Moderator both start with "M". Magix employees have a Magix logo on their avatar.

It's quite common for the end of long-GOP files to not be quantized when decoded in Vegas. I see the same here in VP16 build 261 with an HEVC file from a GoPro HERO6 and an AVC file from an A6300.

The loss of contrast sounds like a colorspace issue.

How are you transcoding?

From what I can get from your posts, you are concerned that Vegas is not previewing your files in real time, yet they are playing back smoothly in a variety of players. Is that correct?

Unfortunately, that is not a valid comparison, nor is your assumption that it can be fixed with a software update, since the decoding methods used are entirely different between players and nonlinear editors.

First of all, your HEVC 60p footage is demanding. If Blade Runner in 4k plays great on your home theater you are doing better than a lot of folks because the orange fog translates to temporal complexity.

That was just an example. GoPro and NX1 footage are more demanding on an editor by another order of magnitude.

Now, a player fully decompresses only one out of three or four hundred frames (I) per scene, the rest containing instructions that get the job done a lot faster (P, B, b-pyramid.) The predictive nature of interframe decoding also conceals a multitude of sins. Particularly, stream errors that will cripple Vegas or Adobe will play just fine in your favorite player!

Unfortunately, none of this has any meaning for nonlinear editing. Each pixel in Each frame in Each GOP must be fully decompressed (inflated) to raw uncompressed bits to let us work at the frame level in any nonlinear editor! That's the equivalent of turning each p- and b- frame into all Intra, whivh means a whole lot more uncompressed data than you started with, and thattgets stored up in memory buffers, as much as they can handle.

Now, previewing in real time in a NLE places a big system demand even with everything optimized. Add multicam, effects, and motion, and your state-of-the-art system begins to look a bit pale. The real time processing demands soon exceed system capability, and the preview frame rate slows down to something it can handle.

Vegas' improvements in real-time decoding and processing speed over the last fifteen years have all depended on hardware and driver improvements, not software updates.

If your SOTA system isn't keeping up, we've got Proxies! And Intermediates! And Prerenders!

And take heart. 128 bit consumer Operating Systems aren't that far off in the distant future...

That's why I asked if Tripleflip could edit with his mediaplayer, because he made a comparison between a mediaplayer and a NLE.

Nice explanation Musicvid.👍

Wondering if there is going to be an update for Vegas Pro to Optimize playback in the timeline. I got Intel i9-7980XE (18 core overclocked to 4.6ghz) Nvidia 1080TI and 64gb ram. Fastest M2 SSD.....

So playback in vegas of 60p footage plays at about 40-50fps...using 90-100% CPU. Opening same file in any media player uses 2%CPU.....So obviously my computer can play it back without issues without slightest stress or issues for the system.

Same story with my NX1 files but at least it can keep smooth playback at 30p and 70-100% CPU Usage.

Problem is I MUST use Multicamera and having NX1 and GoPro footage makes it crawl at 1, yes ONE Frame per second....

So the question is, is there going to a fix for this issue and HEVC timeline playback or Don't count on it in this version?

Thank you!

 

You are playing back 60P and CPU usage at 90-100% that is telling me that your 1080Ti is not really doing any works on Vegas. You got a very powerful system but your video card is not the one you should use or choose. 1080Ti is powerful in all other aspects but weak in Vegas. You said you have been using Vegas for a long time and you should have known that AMD card is a better choose, specifically for Vegas performance concerns. I willing to bet you. If you remove the 1080Ti and drop in the AMD Vega 10 Frontier Edition card in there. You will a big different in improvement over your 1080Ti card.

I got very good in play back on 4K 30P Samsung NX500 hecv file on Vegas timeline. I will try test out some footage in 60P and try it see how its perform. Anyway. I am able play back 2 tracks multicam at best/full @ full frame rate. But I when I pump between shot I get 15 frames and bump back up to full frame.

Nice explanation Musicvid.👍

Very nice and giving exactly the sitation when you work with a NLE.

This command of Musicvid should be a must for all the gameplay recorders to read before complaining here about the Vegas NLE !

Can you edit video with a media player?

I get it better now, but still other media editors can use GPU and playback no problem, so its really software bottleneck.

Can you Please try go pro 7 60p footage and see how your system handles it and your cpu usage, I can send you Nx1 and gopro test footage if you like, i would totally switch graphics card if AMD Vega 10 Frontier Edition works better, just tell me which graphics cards work best and i'll get that card. I don't care about speed up render times, all i care about is real time playback of gopro 4k 60p HEVC and NX1 HEVC. Im willing to spend $ if its going to make my life easier.

Not sure if its asking too much but if you can can you check Fuji X-T3 10 bit 60p. My system is at 1fps of that footage so basically its impossible to do real time playback. Thats why im not buying that camera, but if putting it amd card can solve that problem I'd definitely switch my lovely NX1 for X-T3

I can send you Nx1 and gopro test footage if you like,

In order to make a good decision if I shall switch from my GOPro 5 to the 7 I like to test some stuff from a GoPro 7.
Atthough my framerate will become 50p I like to test how my hardware ( from signature) will handle your files, so please give us some footage on a cloud service.

These are the figures played on my desktop from signature

They speak for themselves I think.
For me an indication to stay with my GoPro 5 while I have enough with 2,7K AVC rendered to 1920x1080 50p with the help of Vegas Stabilisation, Prodrenalin 2 and Prodad Mercalli 4 to look on my 4K TV.
My old eyes are slightly seeing the little difference between Full HD and 4 K slideshows I also make, so 4K is for me yet not so important for video.
 

I download your footages and here is what I got on my system.

Single track XT3-4K 50P 10 bit ----- VP16 TL BEST/FULL settings run 48-50 frames CPU 68-73% GPU stay solid @ 10%

Single track NX1 4K 30P VP16 TL run BEST/FULL settings run full frame rate CPU 40-48% GPU stay solid @ 6%

Single track GoPro 7 4K 60P VP16 TL run BEST/FULL settings full frame rate CPU 67-72@ GPU stay solid 12%

XT3 footage bouncing between 48-50 frames. The other two stay solid full frame rates. I can not see a way to multicam editing with XT3 and GoPro 7 footages. At least not yet. Perhaps is the near future with far more powerful CPU and GPU. The codec is the major factors here.

I can edit 2 tracks 10 bit GH5 with All I codec and I got full frame rate at BEST/FULL on a 10 32 bit Project Properties settings. I when tried your footages with 2 tracks. Its started out at full frame rate and taper it down 3 frames.

Here is a snapshot of the system in my profile with two simultaneous tracks on Vegas Pro 14 after converting to...

MagicYUV

Sony YUV

Uncompressed

Proxies

Which sense does it make to preview 2160p60 in a VP16 TL with best/full settings on the preview screen inside the Vegas UI?

My former report with that GoPro 7 file was without proxies.

Wow thats really promising, what about running it in Good preview in full/half i've never used best because its so Demanding on the CPU and there is no way to run it on my end, so 95% of the time i run it in good/half, OMG i really hate to ask but can you rerun that xt3 and gopro, in multicam?

is there any video card that can do realtime preview even better then AMD Frontier Edition Vega 10 16GB HBM2? and does that card run games well?
