Super slow rendering in Vegas 19 Pro

mike0323 wrote on 2/15/2022, 12:27 PM

I have a Lenovo Legion 5 laptop with an NVIDIA 1660 ti, 16 gigs of ram, and a generation 9 Intel i7 CPU.

I am working on a 3 camera project (all at 4K, 24fps). I have added color corrector, color grading, color curves, and brightness & contrast to two of the video tracks. The whole video is just over 5 minutes long. I have tried rendering to mp4 and to a Sony codec that I can't recall at the moment (I don't have my laptop with me. Both codec properties matched my file properties.). I know those effects can be intensive, but I am having a couple of very disturbing issues:

The video preview is so lagging that if I just place the curser at a certain point, it will take several seconds for the frame to show in the video preview (even when set to draft at one quarter).
The rendering time is astronomical!

I am also running Windows 11.

Is there anyone out there who can help?!?

@mike0323 Hi, i think you said it, those effects can be intensive, even on my machine Vegas can be laggy as soon as I add a few fx's,

Windows 11 not officially supported yet apparently,

Are the 4k files AVC or HEVC?, HEVC can be a bit more intensive, i avoid them.

Make sure you have the latest Studio Driver for the GPU,

When you say '3 camera project' ? can you expand on that, you can upload a full screen pic using the arrow button next to the smiley at the top of a new comment,

Thank you Gid! I can't upload a pic because I don't have my laptop with me. By 3 cameras, I mean three different video files synced up. It is from a live music recording of my band and I used 3 separate cell phones (1 Galaxy S21 Ultra, 2 iPhone 12s, all at 24fps). I will have to wait until I get home to see if the files are AVC or HEVC. Honestly, I get confused on that. The files are .MOV and .pm4, if that helps.

It may be that the files and the effects are just too much to handle, but it seems like the rendering time is way too long!

Also, I did download the latest studio driver yesterday, but that didn't seem to change anything.

@mike0323 👍 I have the Samsung Galaxy S21 Ultra, in the camera setting there's a Auto HDR, & in the Advanced recording settings there's Reduce file size & HR10+, turn these two off, if they're on it'll record in HEVC

Both MP4 & MOV are containers, there can be a variety of things in there.

AVC H.264 - Advanced Video Coding is just a way of compressing & holding the video info, it's been around for quite a while & most programs are pretty happy with it.

HEVC H.265 - High Efficiency Video Coding is just a more modern way of compressing the data, it was developed because of modern cameras & 4k, 8k etc. that produce more info that takes up hard drive space, so therefore they needed to find a more 'efficient' way to store that data,

There's loads more to it & there might be a little bit of bollocks to what i say but that's how understand & remember it,

Your files will show AVC or HEVC if you right click on media on the timeline - Properties - Media , or at the bottom of the Project Media tab, or you can use MediaInfo https://mediaarea.net/en/MediaInfo it's free, after downloading it, right click on the file in Windows folder, open MediaInfo, choose Text from the View tab at the top, it'll show it in there, you can if you want Select All the text & copy to a new comment on here,

What does that mean? Be sure and post your actual rendering time, along the the rest of the information required for forum support, thanks.

Thank you Gid. I did have the auto HDR on, but I had the others turned off. Thanks for the advice.

Musicvid-I apologize for not being more specific regarding the render time. I began rendering at approximately 11:00pm last night. This morning my computer had timed out (my bad. Forgot to change to "never") with 5% rendered. When I left this morning, the approximate render time was around 14 hours. I am sorry that I can't give specifics on which render settings I used, but my computer is not with me. I will post more when I get home. I can say that the render properties are the same as the project file properties.

Again, when I have the information that I need, I will post it.

Thank you, both!
