Some Videos not playing smoothly since update

Thank you for your response, Trevor!

Of course, I always choose the appropriate timeline frame rate and do not mix videos with different frame rates.

To illustrate it again: I take "Sample_Lake.mp4", one of the two sample clips that VideoStudio comes with. Its properties are H.264 High Profile Video, MP4, 30 fps. I place this clip in the timeline, which is also set to 30 fps. I play it, and it doesn't play smoothly. I go frame by frame: Frame 1 and 2 are the same, Frame 3 continues, Frame 4 is the same again, Frame 5 continues, Frame 6 continues, Frame 7 is the same, and so on. The same happens when I simply play the video as a clip, regardless of the timeline.

Another example: I started a video project after Christmas, so before the update. It includes MP4 files from my GoPro and MOV files from my DSLR, all at 25 fps and H.264. Before the update, there were no problems; all videos played normally. Since the update, the described problem occurs with the videos from the DSLR. At first, I thought it might be a problem with MOV files. So, I converted them to MP4 using Adobe Media Encoder, and they worked correctly again. Later, I noticed that the stuttering not only occurs with the MOVs from my DSLR but also with other clips, such as a TV recording, also MP4 H.264 25 fps.

The stuttering of the clips is not tied to a specific file type, encoding, or frame rate. Unfortunately, I don't know what the issue is. I only know it has only been happening since the update. Also, it's unlikely to be a problem with my computer (Lenovo AIO) because I have the same issue on my Surface Pro 9.

Is everything working normally for you? How about the sample clip "Sample_Lake.mp4"? (Perhaps not the most beautiful example, but a good comparison object.)

Hi grupsua
Yes I am seeing problems with the Sample_Lake.mp4 video

Playing at first seems ok, but look closely and the water glistening just does not look right.
Nudge through the frames, I hit the “F” key and 2 frames move the third press is static, throughout the video.

Normally I use MTS pal 25fps / 50P there is no problems, 25 and 50fps play ok without the static frame.
Using my own MP4 1920 x 1080 x 50P and I have the same problem.

Tested a Mov from the overlay library as ok

I can nudge the video from the library and still a problem, that sort of rules out the timelines.
Changing the programs TV system from Pal to Ntsc has no effect on this.
Deselected Hardware acceleration, still a problem

As “moltllest” you should also report to Customer Support, I will be doing the same.
Thanks for your input here moltllest

Did anyone receive an update from customer service? nothing on my end

Good evening,

Today, I received a response from support – unfortunately, after four days, it was quite disappointing. For now, there were only a few simple follow-up questions, no solutions yet. I have described the problem again in great detail, and I hope that support will now engage more intensively with it.

Any news from your end?

Using the Sample Lake video, I have the same issue with VS2022 as well as VS2023 but VS2021 plays through the frames correctly, so a coding issue !!!

Hi Robert
I do not have a problem using 2022, I had to install to test, did not install the Bonus features.

2023 I am also experiencing slow responce after Inserting/ drag and drop video clips to the timeline.
Very slow, upto 20 seconds to display a 1 minute clip.
Compared to 2022, is almost instant.
