Blu-ray media created playback issue. Image bounces/jitters

calamar wrote on 9/3/2025, 8:29 AM

I made my first Blu-Ray disc with Video Deluxe 2025 Plus. It was an easy one from 3 mp4 videos with a resolution of 1920x1080p @ 25fps and I created a simple menu to browse through the three titles in the disc.

I used H.264 codification and adapted bitrate to fit a 25GB disc (17.700kbps bitrate). It was selected the default config for "Blu-ray 1920x1080p24". That's the only thing that I didn't notice, that this default config is 24fps and my media is 25fps.

So, I burned the disc and tested playback on my Blu-ray player and my PS5. In both, video is not fluid/smooth but it makes some kind of frame jumpings or jittering effect. If I do a fastforward and play again action, sound plays but image freezes. I opened the .m2ts files the tool creates on my hard disk and played them with the Windows Player and they look smooth, not like my BD players.

Do you know what might be happening? Is it because that fps thing? Why isn't an option to create 1080p24fps and only 1080i?

Thank you!

Hi

The change (reduction) of frame rate is the most likely cause of the jitters.

Try the following:

Change the project settings to 1920 x 1080 50fps, the 50 fps helps with conversion of progressive video to Interlaced.

In the Burn dialogue ensure you select BluRay, not AVCHD, and in the Encoder settings, Presets select BluRay 1920x1080i PAL (Default), this is 25fps .

For testing I avoid burning to BD-R discs using either BD-RW rewritable discs

OR

Burn to ISO image using the Image Recorder option, this can be 'mounted' using Windows file explorer, right click the ISO file and select the Mount option if it is visible, or select Windows File Explorer and use either VLC or PowerDVD to play the disc

There are more options (presets), the 1920x1080i 25 fps is the standard for PAL BD discs

Thank you, John!
I'm trying those configurations. Let you know the results once the BD is ready.

With this parameters, encoding just the first video (around 60min long) takes more than 8 hours. Even I have GPU encoding enabled, when I start the process a message appears saying GPU acceleration was disabled and suggest to update graphics driver. With the 1080p24 configuration, each video didn't take more than 20 minutes for encoding.

Is there anything I can do to improve the encoding time?

Thank you!
