What’s your source frame rate?
Maybe asking the obvious but are you sure your source is interlaced?
You can control the size by controlling the data rate but it’s not mission critical in this case although you may be using more of your weekly upload limit than needed.
Are you checking the file before upload or after as there different factors in each case ranging from your computer’s playback capabilities to your internet connection.

craig,

thanks for your response. the source frame rate is 25 and i’m sure it is interlaced (shot on fx1).

yes, im checking the file before i upload it. so im not going off the uploaded file.

to be honest, i’m not quite sure what increasing the data rate does but if it adds quality maybe i should try this, although i’m not sure by how much i should increase it. increasing the file size doesn’t bother me, as long as its under 5gb and at the moment with the current settings its only 1.16gb.

thanks
adam

Are you using Compressor 3.5 or 4?
In 4 use the Video Sharing Services HD 720p Video Sharing preset as is.

Otherwise try this although there are variations.

I don’t see a data rate in your settings. Maybe you have it set very high or to Automatic. Vimeo would still handle it without issue but maybe your computer can’t handle playing back the source file.

File size is a duration times data rate.
