I've run into an issue regarding a screen capture film i've made.

It's 7 minutes long, that's fine, but it's 1.82GB in size. I can export the file so that it becomes a Quicktime file (Which I would have thought also meant making it smaller), but it stays as 1.82GB.

So, does anyone know a fast way of making that file smaller, without losing quality? I could run it through iMovie HD, but the last time I did that, I lost a LOT of quality.

For screen recording I am using: ScreenFlow

I am using Mac OS: 10.5.8 (Leopard)

Also, if it helps, I've going to be out and about for a few hours at a time within the next few days, so exporting time and conversion time isn't an issue. ;)
 
QuickTime is a wrapper, so the video could still have been encoded a number of ways. H.264 encoding is resource intensive, but tends to look great and also offer good compression. I assume Screenflow lets you control QuickTime export settings?
 
Yes, it does, but the file, although size has not changed, stays at a large 1.82GB. I ran it through iMovie HD and produced a '720p' copy of it.. I highly doubt it was anywhere near 720p.

Basically, I just made a shorter video, (500MB) and allowed that to upload to youtube. Still on the look out for some good video editing software, Adobe After Effects comes to mind, but I am not experienced with that.
 
I used Handbrake since my Canon T2i records in .mov files. I took an 250MB 720HD 47 second video and brought it down to 35MB without losing quality. You can play with the settings to get a clear picture as possible. Here is a link to the video I made.

There is Virtualdub for AVI files but I don't know if the program works on macs. Dr. Divx is also a good one that is free and I've compressed 10 minute videos nicely with it(though you may want to adjust the brightness a little to the video so it does not appear darker after the conversion).
 
I recommend Handbrake. It's a great program, I use it to convert all my personal DVD rips to reduce their size without noticeably affecting the quality. 👍

It's really the only video conversion program you need, so long as you're fine with the fact that it can only convert to MP4 or MKV.
 
I can convert and export the file in to any type of file I wish. With mac it is as easy as changing the extension.

I will have a look at Handbreak. Seems to be the best option.

I will export the videos in the highest quality possible, and run it through that.

Thanks for the help guys. Much appreciated!
 
You will want to keep the data rate quite high around 2000 to 2500 kbits/sec this will ensure the image sability is quite nice, from there change the audio to stereo and not some crazy HD or surround. this should bring your file size down, this can be done in QT pro or Handbreak is use both on my Mac.

You don't need that high of a bitrate. I use 1200 for converting my DVD rips, and the loss in quality is nearly imperceptible. But then again, I'm using some high B-frame and analysis settings, so it takes some time to pull it off.
 
Yeh I use handbreak to convert DVD's to play in my HTPC and 2000 is what is used and it knocks them down from 6/7GB to around 2GB. I just used the same settings or as close as I could get to as the movie files from iTunes.

Going lower will inevitably lower the file size, if this is needed then doing two passes or using other settings to counter the lower bit rate will keep your files nice and small and good quality it's as Yaywalter says though it can take some time to convert.

xilisoft video converter 6 is what i use for all my bluray movies you can convert anything and you can specify files size etc i would say 700-800mb from 1.8gb wouldnt lose you too much quality 👍
