I have tried the following values with varying success.
Format Code Fmt1 Fmt2 Fmt3 Fmt4 Fmt5 Fmt7 Fmt6
Frame Width 720, 720, 640, 640, 720, 640, 640
Frame Height 576, 576, 512, 512, 576, 512, 512
Data Rate (kbps) 8000, 15000, 15000, 11000, 6000, 14804, 14432
Total Bitrate (kbps) 8224, 16536, 16536, 12536, 6384, 16340, 15968
Bit Rate (kbps) 224, 1536, 1536, 1536, 384, 1536, 1536
Frame Rate ALL 25 Frames/Second
Channels ALL 2 (Stereo)
Audio Sample Rate ALL 48 kHz
The Fmt 1 values give varying and indifferent results. As for the rest of the formats, I cannot see any difference (if at all). The good stuff (and the bad stuff) is the same on all of the formats. The sound seems to be good enough no matter which conversion format is used.
I realise that if my video is not too good then converting it will not improve the quality. I also realise that I may be using values that do not alter a thing.
I am going to give it another go – but before doing so I but I would appreciate some guidance as to the optimum settings to be used. Also any “tricks of the trade” that I may be able to utilise. There is a mixture of normal and extended play videos if that is relevant. However, the good or bad results don’t seem to be specific to either normal or extended play.
Many thanks in anticipation for any guidance you can offer.
