Quicktime mysteries

So the other night I finished recording my brush demo in ishowU HD Pro, and the entire video came out to be 2 hrs 35 minutes long. I used quicktime to edit the clips together, and then I used MovieFunnel to speed up the video to be 25 minutes. 

Speeding up the video through MovieFunnel was easy and it saved out a different version of the file when I selected "Full Self contained movie". But here's where the problems start. 

My original file was  660 mb. The 'funneled'  version of the video came out to be just a tad bit larger. I looked at the video and found that my 25 minute version had been added to the front of the 2 1/2 hour version. 

Ok...select in point...select out point...trim to selection...Save...file size smaller right? WRONG. 

It seems that Quicktime still keeps the original file refrenced. I've tried exporting a new ipod version of the video using VideoMonkey and got some wierd results. Instead of creating a video 25 minutes long...it referenced the old video and output 1hr of it...what the heck!?

Ok so here's what I want. I just want to export a new 25 minute version from this 'funneled' video and then send it to vimeo. Any suggestions?

Hi Matt,

Great site you have - its really good to see the camera moves on your work. I particularly like 'The Pass' nice work!

my guess is moviefunnel is leaving all the frames intact but simply changing the framerate tags and stepping eg: play only even frames. Which is how it can spit out the file so quickly instead of a full re-encode.

As for quicktime well... macdot did a whole podcast on quicktime's idiosyncrasies which explain better than i can here:

Is iMovie not an option?

Pengilly, Thanks for the reply. I figured everything out and will be posting a tutorial on how I put the demo together soon. iMovie wanted to re-encode the files to import them and the quality was horrible. Strange because I edited my demo reel together with iMovie. iMovie also wasn't very helpful in speeding up the clips and wouldn't speed up the clips all into one file. *shrug* It's over now.

Timmy, Thanks for the reply. I lover your blog man and look forward to maybe working with you in the future!

Same goes for you Rockhopper
