A6400 and a7S2 should give smooth playing 4K h264 with any recent processor.

In general Intel decoding is the most compatible in Vegas so I'd suggest 12th generation Intel.

10 bit 60fps HEVC may not play well on any machine at present.

what's the best setup the would give me no frame drops during best quality playback because i experience this allot on Vegas Pro Even When Editing 1080P. i always have to make proxies.

You won't get smooth reliable playback of HEVC in Vegas due to it not having a multi-threaded playback engine, it is multi threaded for AVC playback but you will also experience framedrop at times . 12900K with your 3060 and 3600mhz DDR4 with good timings would work great. 12900K may not give better playback over a 12700K, it probably CPU renders faster due to the extra efficiency cores.

That's not possible unfortunately. It is better to temper expectations. Here's a thread from a 12900K buyer

Thanks for your answer and as for the thread he was using that version of Vegas pro on windows 11 which didn't had support for it that time. And that version didn't had good playback.

The IGPU on Intel Core I9 12900K Works very good on Adobe Premiere and Davinci resolve it decodes all the newer codecs 8Bit Codecs are no problem at all and gives a smooth playback on 10bit 4.2.2 24fps HEVC codec it works very well only struggles a bit on 60fps. i wonder if Vegas Pro 19 Utilizes the IGPU the same way as Adobe Premiere or Davinci resolve.

. i wonder if Vegas Pro 19 Utilizes the IGPU the same way as Adobe Premiere or Davinci resolve.

Yes it does, the problem is the playback engine for HEVC. Premiere and Resolve can use all the cores of your CPU, Vegas only 1 or 2 cores. The GPU decoding aids in taking the load off the CPU but playback of HEVC can require more CPU then Vegas is able to access.

so it will struggle on HEVC 10Bit for now but what about 8Bit HEVC.? will 10Bit and 8Bit H.264 have similar issues as HEVC.? and 8Bit on any format will playback Smoothly.? i think its just the 10bit HEVC that Vegas has problems with.

We think it's the same for Intel decoding, but there aren't many users here with 11th and 12th generation Intel CPUs who use 10-bit 4:2:2 HEVC who can confirm. If you really aren't happy with the performance in Vegas and don't want to create proxy files, you can always use that CPU with another NLE.

The more data required to be decoded, the more CPU is required, so in the scenario that we're always using GPU decode via IGPU, at a given resolution and frame rate, 420 10 requires more processing, and 422 10bit even more. HEVC 420 8bit at high frame rates and high resolution does not work well for the reason I mentioned: not able to access the full CPU (multi-threading)

A 12900K is good, it has high frequency and IPC

 

i wonder if Vegas Pro 19 Utilizes the IGPU the same way as Adobe Premiere or Davinci resolve.

I found a screen capture I made a while ago comparing HEVC playback with Vegas and Premiere. It is a 120fps HEVC 422 being played back(No gpu decoder). The point is not smooth playback, it was to show the available CPU cores used for HEVC decode. Premiere uses all the cores, while Vegas only uses what looks to be 2 cores.

Thanks to everyone for there help just wanted to give you guys an update

i recently Build My New System

Specs are

• Intel Core i7 12770K
• Nvidia RTX 3060
• Corsair Vengeance DDR5 5200MHz 32 GB
• ASUS ProArt Z690 DDR Motherboard
• 2 Samsung NVMe SSD
• Corsair iCUE H100i ELITE CAPELLIX Liquid CPU Cooler
• Corsair RM850X Power Supply

I must say its a beast. I edited 4k H264 and H265 8-bit 420 and 10-Bit 422 Preview quality set to Best Full

after color grading i would set it to Best Half and it plays back without any dropped frames. Timeline performance is great. Rendering is fast. and its able to utilize both The IGPU and RTX 3060 they work together which is what i expected. just for test i also tried editing Red Raw 6k and Blackmagic 6K and it also plays back smoothly without any dropped frames i didn't create any proxies.

and for those who also use Adobe Premiere Pro or After effects at times and DaVinci Resolve for Color Grading it works even smoother and can utilize much more of the system. i hope in the Future Vegas pro updates for windows 11 and the new Alder lake CPU will definitely make things even better then what it is now.

Good info todd-b! Any plan from devs to support HEVC multithreaded decoding?

What case are you using and how quiet is the machine when asleep. Does it get much louder when rendering?

@relaxvideo SO4, the HEVC GPU decoder is primarily single threaded as seen in the video, but legacy HEVC (no GPU decode) is multi threaded, The problems are a few, no GPU decode, less compatible with modern HEVC files, no 10bit support, it will force SO4 decoder while in Legacy mode.

I'd love them to start talking about the HEVC decode situation, because that may mean it's being fixed for VP20, but so far they choose not to comment

Yes, VP20 should support it! It's 2022 after all.
