I have two seperate videos that I’ve tried different settings and all of them add audio lag.
The videos are ~65 mins each before setting the Marks.
I’m running the following:
Windows 11 Pro 24H2
OS build 26100.6584
Processor - 13th Gen Intel(R) Core™ i9-13900KS (3.20 GHz)
RAM - 48.0 GB
Video - NVIDIA GeForce RTX 5090
The video resolutions are 720x480 and I used the following command to capture them:
#00 Original Capture:
set FFMPEG=C:\Apps\VHS\ffmpeg\bin\ffmpeg
set OUTDIR=C:\Apps\VHS
set DEVICE_VIDEO=CY3014 USB, Analog 01 Capture
set DEVICE_AUDIO=CY3014 USB, Analog 01 WaveIn
set FILENAME=capture_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.mkv
set FILENAME=%FILENAME: =0%

The audio is perfectly in sync in both videos before using both Starlights.
For Starlight Mini, I choose the following:
Enhancement - On
Output resolution - 2x Upscale
AI Model - Starlight
Model variant - Starlight
For Starlight Sharp, I choose the following:
Enhancement - On
Output resolution - Original size
AI Model - Starlight
Model variant - Starlight Sharp
The weird part is that I beta tested Topaz Video AI 7.2.0.2b and the audio was in sync for Startlight Mini. However, the quality of the converstion was not that great, which this version fixed.
