View Full Version : Your 7D Compression Settings using MPEG Streamclip?

I'm using MPEG Streamclip software until I get the new Canon Plugin for converting to ProRes to work. I shot in 1920x1080 30p and want to convert it to ProRes LT. What settings are you guys using to get the file size down as much as possible but still have it look great.

The first option MPEG Streamclip gives you is do you want to export it as QT in the drop down box. What are you guys selecting there? I've been selecting "Export to QuickTime" or is their a better option?

Then I choose my destination and then the Compression Drop Down big box comes up. I choose Apple ProRes 422 LT and Sound as MPEG-4 AAC.

Now frame size is a little confusing cause they have 3 1920x1080 choices to choose from.

Do I choose the 16:9, Unscaled, or HDTV 1080i option.

I don't want to have to rerender the clips in Final Cut if I can avoid that and the file size doesn't seem to change much for instance a 700mb clip only went down to 600mb.

This is for a wedding video on DVD and Blu-Ray.

Thanks.

Hi Kelly,

The Canon/FCP plugin is available:

Should answer all your questions about transcoding:

Canon Professional Network - Frame rate conversion (http://cpn.canon-europe.com/content/education/technical/frame_rate_conversion.do)

ProRes is a constant bit rate. The only way to lower the bit rate is to lower the frame rate or pixel count.

Thanks Joel. I did install the new plugin but I get the "unexpected file format" error. Will try it again.

Did you reboot after you installed it? That might help. I got the same message but I'm using the T2i. Just thought I'd give it a try to see what happened. Didn't expect it to work.
