2024 Update made rendered videos choppy

[Angus690]

Just update yesterday.. Now every time I save videos, they come out very choppy like the frame rate is wrong but its not. All the settings are the same and match the original video. Tried multiple different formats, all the same.
Anyone else experience this? Can I roll back an update? Im about to just go back to using 2021 version, at least that works.

Welcome to the forum -- though I assume you have seen that Alludo is closing us down on 12 February. So let's see if we can help in the meantime.

First off, can you tell us the Properties of your video and where it comes from: video camera, smartphone. Right click on one of the original clips in the VS timeline and go to Properties and either take a screenshot of the Properties box and post it here as an Attachment, or copy out all the properties. What editing are you doing. If the settings are the same as the original video, are you saying you are outputting the project with those same original properties? And is the choppiness only within Video Studio or also in whatever player you are using?

I've updated to Video Studio Ultimate 2022 to 2023 and when I'm editing videoclips from my Gopro or Canon cameras, everything is fine but clips from my Apple phone are choppy. Thanks if you can help me.

Smartphones, particularly more recent ones, tend to use variable frame rates. VideoStudio does not like these, and prefers standard ones like 25/50 for PAL or 29.97 (or 30) and 59.94 (or 60). Sometimes it won't even accept them, but if it does, the result is as you have found -- somewhat jumpy or choppy. In those cases we can only recommend that you put the smartphone video through a third party video converter like the freeware Handbrake some of use here use. That can be set to near identical Properties for the new video, but using one of the standard frame rates. Then insert that newly converted video back into VS and the choppiness should be gone.

Hi Ken,
Thanks for your answer. To resume, my clips are 1920x1080, 30fps as always, I've been using these iPhone clips all the time and the videos rendered on VideoStudio were perfect and very smooth until I updated to 2023 version. I have tried Handbrake as suggested but not any better. I have tried the same clips to make a new video and all are choppy versus those before the update.
Thanks again.

Is 1920x1080, 30fps your project settings or the actual properties of the clips in the timeline. To check, right click on one of the clips in the timeline to see if it says 30 fps and not something like 29.583 or something like that.... If, for instance, you have set output to use "Same As First Clip" and the first clip has one of those irregular frame rates, then VS will try to apply that irregular rate to the whole project, so the whole thing would be choppy...

I'm harping on this point since we get other users complaining of choppy video but when asked, they identify clips which use irregular frame rates. We are not at all deluged by users who use regular frame rates complaining of their output being choppy...

[Marc J]

It is my project setting and the iPhone videos are 30.006 fps but they were working fine before. Even my Gopro clips are not exactly 30 fps, 29.97 and they work perfectly.

[Ken Berry]

Yes, but the NTSC standard frame rate has always been 29.97 fps (and 59.94 fps). That is not an irregular frame rate -- it is the standard. It is called 30 (or 60) only as a sort of shortcut. And I'm afraid that 30.006 indicates that you are in fact using an irregular frame rate. And they need to go through Handbrake...

[Marc J]

I made a test, a clip from my phone on the timeline, then I took the same clip processed through Handbrake and added it on the timeline. The original is 30.006 and the modified is 30. The result is the same on the final video, both are choppy. What I don't understand is that it has never been a problem like this before the update.
Thanks Ken

There has been a similar report on the new forums
https://psp-vs-forums.freeforums.net/th ... crollTo=85

We can see the problem using the Sample-Lake video, simply nudging through the frames one by one and the third press is static as though a duplicate frames.
I do not have problems using MTS video, it appears to be associated with H.264 types.

Marc,If you have not already done so please report this to Corel Support

Thanks Iata, I've opened an account in ProBoards and seen the post about this problem. I will also report the problem to Corel Support.
