Hi
I make some screencast with VLC Media Player, it captures my desktop and exports the file in H.264 at 25 fps. Then I edit this in PPro and also export the clip in H.264.
All is well but... The original video files from VLC has a top quality with a very low bitrate (200 Kbits/s), and when I try to export the edited video with the same bitrate from AME, the quality is just horrible! Artifacts, blurred, with some blocks... Even if I export with a bitrate more than 20x higher than the original file (4400 Kbits/s), the quality is not as good as the original.
Here is a comparison between the three exports:
Can you explain me why there is a so big difference even if the bitrate is multiplied by 20? Here are the export parameters (with a bitrate of 400 Kbits/s):
Thanks a lot for your help and please excuse my poor english
