Thank you for this substantial video software,
I’m trying to come up with a bash script to automate video upscaling based on the Topaz AI Video FFmpeg command.
For some reason when running the script I get different output size each time (a couple of bytes). That’s not the case when I run the exact same command with the UI.
Am I doing something wrong ?
My script is the following:
#--------------------------------------------------------------------------------------------------
# Configuration
#--------------------------------------------------------------------------------------------------
ffmpeg="$topaz/ffmpeg"
export TVAI_MODEL_DIR="$model"
export TVAI_MODEL_DATA_DIR="$model"
#--------------------------------------------------------------------------------------------------
# Run
#--------------------------------------------------------------------------------------------------
# NOTE: This line comes from Topaz Video AI (right click > FFmpeg command).
