  Quicktime file size?

  Posted by Van Kowalski burdge on June 8, 2009 at 8:44 pm

  I have been using Visualhub to do this but I wondered if any other software can do it. mpegstreamclip, compressor and QTpro do not do it…at least I could not find the settings.

  When transcoding to h.264 how can I limit the finished file size to under 500 megs???

  The reason is many of the online video hosting services have a 500meg limit.

  tia,

  File size is very much related to data rate.

  Scratches head, isn’t this common sense?
  kbits/second is size when you know the total number of seconds. Of course there’s some variance especially with VBR encode as one may over or under shoot a bit but you can certainly get very close.

  Craig is spot on but if you still need the facility I seem to remember that Cleaner from Autodesk can limit to filesize but don’t expect it to get it exactly right down to the last bit.
