    How to re-encode my video for internet upload?

      Hi,

      I need to upload a video to vimeo.com,

      I exported it out of AE as a lossless quicktime animation.
      Next thing i did was to export it out of quicktime as a MOV :H.264, double pass.

      First the file size was just 17 MB, it astounded me, so I exported it again.

      But now i used: HDV 1080, it looked even better (file size 64mb) but when i uploaded it onto vimeo my ramp was looking awful, even though i uploaded in HD?
      Take a look for yourself:http://vimeo.com/3057769 (password: azerty789)

      How can I solve this awful-looking ramp?

      Thanks in advance!

          By not using compressed formats. ;-) Ultimately there will always be some minor banding, especially with MPEG derivatives that use chroma undersampling to increase compression efficiency. Unless you can employ the usual tricks like introducing minor noise or adaptive blurring to enforce a different block pattern, there's no way to completely avoid it. Also look into using other tools to do the actual compression. QT Pro is not bad, but other tools may be even better...

            if you want to achieve any kind of peace of mind, try using sheer video codec from bitjazz.com

            especially if you stay on your machine till compositing is finished. for outputting or presenting files you can use their free sheer video DEcoder/reader on any machine.

            maybe you'd never need a dual-pass render for H264 again because your source is almost perfect for a single pass only.

            i can't pray often enough to people who are willed to spend some bucks on that algorhytm.
