HEVC X265 MP4 VEGAS PRO 14?

jengia wrote on 10/1/2017, 8:13 AM

Hello everyone, I imported my video file on Vegas 14 which is compatible with hevc x265 encoding and reads it just fine but when I try to play a preview of it it's laggy, like I can just import it nothing else, I can't edit or anything. I know that I might be lucky about space with x265 but suffering at the performance compared to x264. Is there any tips or something to get it fixed? How can it be compatible but not working properly at all? I don't want to go back to x264 so any help would be much appreciated. Here's the media info:

VP14 just can't decode HEVC as smoothly as AVC.

Try the smooth playback tips in this thread: https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-make-my-video-preview-play-smoothly-in-vegas-pro--104624/ In particular, GPU acceleration may help.

At this time, only a faster PC. Specifically a higher clockrate CPU.

How can it be compatible but not working properly at all?

Compatible means it can be imported and shown. Working "properly" I assume you define to mean real time playback. This means your PC is fast enough to handle the task.

No matter what we can always have files where the video decoder or I/O bandwidth requirements are beyond our computers capability. HEVC has the highest CPU decode overhead of any codec I know. It is compact but there is a cost for that compactness.

Just because a PC can edit HD smoothly does not mean it can edit UHD smoothly. Similarly, just because a machine can edit AVC smoothly does not mean it can edit HEVC smoothly.

Using a hardware HEVC decoder may allow HEVC to become "editable" on many/most PCs, assuming the PC has a hardware HEVC decoder.

I would suggest a lower resolution proxy file.

I would suggest getting a Netflix account.

funny you would say that, but I already have one lol

Hmmm, yeah that could made things a little bit better.

Thank you for the tips, I've made most of the changes already so I don't think there's anything else to do.

Yeah, I think you're right! So, I should stick with x264 decoder for now until I made an upgrade. Thank you very much for informing me. Codecs aren't really my best suit lol

Also, you made me curious about which part of the computer determinates if it's actually suitable for HEVC files. CPU and motherboard I assume? I can give you more info about my pc specs if you want to.

"I can give you more info about my pc specs if you want to."

It never hurts.

Some one already mentioned you need a more faster PC to play back HECV file smoothly. I am able to playback smoothly best full in UHD from Samsung camera in VP14. My PC kinda old but its a 4.5Ghz 6 cores 4930K. You will need to have 6 cores 4Ghz+ to play back .h264 smoothly.
