I’m upscaling videos from my DVD collection - and had been using Topaz Video AI for a few years. However, I’ve noticed that there are visible jerky frame jumps in my recent videos - which looks to be an incorrectly determined frame rate.
Being in Australia and using mostly Australian-sourced DVDs, the format is PAL with a 25fps approx frame rate.
Using Handbrake to look at the MKV files extracted from my DVD originals (using MakeMKV) my sources appear to 23.976 fps
Topaz Video 1.01 is reporting these being 29.970 fps … which is then also applied to the upscaled exports. I think this likely explains the occasional jerky motion and jumps that I’m now seeing.
I’ve only noticed this occur recently - with the last few versions of Topaz Video AI and the new Topaz Video. I’ve only done a few upscales in the last few months. The problem only noticeable in the recent ones although it’s tricky to say how far it goes back.
Has anyone else had issues with Topaz incorrectly determining frame rate in sources? Is there anyway to override and tell it the correct frame rate?
Hi, what does MediaInfo say? Telecine, maybe Handbrake does pull down to 23.976? PAL-DVD is 25fps & NTSC 29.97, but in some rare case it could be because DVD supports 23.976 but it’s unusual.
What i often do when I’m not sure is remuxe with MKVToolnix and check this file with MediaInfo again.
I also recommend using MediaInfo to show the file metadata.
It does sound like your dvd might be soft telecined, and if so, Topaz Video could probably handle it (the source can be marked as telecined in the input settings menu, so IVTC is applied) :
Can you share the logs and the MediaInfo of the source files with the support team for investigation? It is possible that the metadata tags are being read incorrectly by the app when importing the video source.
