How do you edit and render above 120 fps

In relation to this post: "I can't edit videos above 120fps in Vegas Pro 15" which didn't have any useful answers to me.

Version: Vegas 16

Processor: Ryzen 5 2600

Gpu: Rx 580

Os: Win10

I'm using OBS to record.

I must preserve the frame rate at 150fps to be used in a different project which will use a lot of velocity.

These are my settings, but when I actually click apply it goes back to either 120fps or 59.94.

These are the videos I'm working with.

Also, is there a way to render a video at 150fps?

Changing the field order to None allowed me to go to 120fps, but it does not allow me to go to 150fps

Seems like FFMPEG might help here, but I'm not finding a direct solution, so far.

A couple of ideas, though:

You could use FFMPEG to render the video to frames (JPEG or some other format), read them into Vegas at a "normal" framerate project for editing, render that as frames, then reformat it to the desired framerate using FFMPEG. In other words, use frame serving to create a slow motion version of your video for editing then again to speed up the final edit.

Or...

In the following link the author skipped the frame rendering step and converted a 60fps video to 30fps using this command:

ffmpeg -y -i input_60.mp4 -pix_fmt yuv420p -vsync 0 -r 30 output_30.Y4M

He didn't like it because it created a longer, slow motion, version but that's the workaround I'm suggesting. The key parameters are -vsync 0 -r30 (everything else is IO and video formatting, which you can change.) Presumably the reversal would be -vsync 0 -r 60 (or -vsync 0 -r 150 in your case). From a quick look at the FFMPEG documentation -vsync 0 forces it to use every frame in the source video and -r sets the output frame rate.

I haven't tried these, and don't claim to be any more than an FFMPEG dabbler...

@Folder123

You can easily do this in Vegas using HappyOtterScripts. Here's a demo of a render at 150 fps.

Vegas Pro 17-452

I just typed the desire frame rate.

If it doesn't work in 16, Oh Well!

Just tried V16 and it is limited to 120fps as the OP states. It would appear that you are out-of-luck in V16.
