I have to encode my captured old VHS-C tapes to divx.
I capture at 768x576 then deinterlace with avisynth securebob, resize to 640x480, letterbox and denoise with neatvdeo plugin in virtualdub.
I want them to be at the maximum possible quality but also playable on standalone divx players.
I thought the profiles function was only to show/hide some functions to the user, with the aim to aid him in the choise of the right settings.
But I tryied to encode the same video with the same settings but with two different profiles (home theater and high definition) and found that the HD profile produced a better but slighty less compressed output than the HT profile, with less blocking and more details.
My main question is: if I encode with High definition profile at the normal resolution of 640x480, the video will be playable on "divx home theater" certified players?
And the second question: The video is very unsteady due to its amateur nature so the average bitrate is very high, around 3000kbit/s. Standalone players could have problems playing it? I read that 4mbit/s is a common limit. How can I set a maximum peak bitrate setting? I don't see this option!
MY SETTINGS
1-pass quality based with target quantization=2
insane mode with enanched multithreading
adaptive single consecutive bi-directional
max keyframe interval 300 and threshold 50%
disabled QP and GMC
noise reduction off
quantization H263 optimized
psychovisual enhancements to shaping
