Newbie question about fps conversion

judelaw wrote on 10/5/2018, 7:39 PM

Hi everyone!

I would like to know how Vegas (and maybe other software) handle the conversion of a 24 or 25 fps file to a 30fps file or let say any fps conversion. Does Vegas accelerate or slow the video ? Does Vegas delete frames ? Creates artificial frames? Anyway, how can Vegas manage that without artefacts ?
Thank you.

It depends on the "Resample mode" setting in your Project Properties. Search that term in the manual or Help. The video is not accelerated or slowed unless you set that in the Video Event properties.

The standard setting of the resample mode is smart resampling which creates "artificial" frames, resulting in double blurred images, especially visible with moving objects. A better, smoother solution is slowing down or accelerate the video, which can be easily done by importing the videoevents at projectframerate to the timeline. Converting 24 to 25 or 25 to24 frames works perfect this way. Converting 24/25 to 30 or vice versa gives of course a noticeable speedchange.

Thanks a lot 3POINT ! All the time I have source files that have different fps that I have to mix together. Until now I was rendering at 30fps. I guess choosing the lowest fps among my bunch of files is the way to go, provided the lowest isn't 15fps or something of course.

@ Nick Hope, Tanks ! Yes you're right, it must be more than worth a look.

If you have to convert frame rates more often, take a look at the ReSpeedr from ProDAT. Until 10.10. is currently running an action on Magix together with Movie Studio Platinum. So I came in addition to a current Movie Studio license.

@matthias-krutz probably means the offers mentioned here. A version of proDAD ReSpeedr comes with the New Purchase of VMS 15 Platinum and Upgrades to 15 Platinum and 15 Suite.

Yes, exactly this offer. ReSpeedr is a stand-alone program with optical flow and image stabilization. Among other things it allows a frame rate conversation and a slow motion.

I prefer to keep it simple rather than using additional software.

… then 3POINT's approach is probably the one to go with.

But also consider Blackmagic Design's DaVinci Resolve - which is free - which does include Optical Flow as part of its rendering options. Unfortunately, the downside for you will probably be that it is additional software.

All right, what will this software do in this case, that Vegas won't?

Dexcon wrote on 10/7/2018, 7:31 AM

VP doesn't do Optical Flow, but DaVinci Resolve does as I highlighted, as does ReSpeefr as previously pointed out by matthias-krutz.

Perhaps it would be good to check out the suggestions you have received on this forum and then get back to us after you have tried them.

I would, but not before knowing exactly, or at least have an idea of, what it does concretely, I 'm trying to find a tutorial.

Good grief! I am at a loss ...
