Optimize Quicktime Filesize

Edit: I've now solved this problem. I was using Export > Movie, when I needed to go to Adobe Media Encoder to find more extensive options. I kept most settings the same, but believe turning 'Bitrate' off may have decreased the data rate. I got the filesize down to around 120mb, which is much better.

Hi all. I did a search but had trouble finding this... I'd like to know how to understand these quality settings and why my new video filesize has jumped up.

After screen capturing a video and editing it with Premiere CS3 (sorry it's old now), I'd like some help optimizing the Quicktime filesize. I was wondering if I can get the ratio back to 1:1 at least.

I have tried to best match my project settings to my original video type, but when I export my edit, the filesize increases from 55mb (10min) to 963mb (7min).

Original video Settings

- H.264 Codec / AAC 44.1khz, 448kbps Audio
- 1280*720 @ 25fps
- VBR Bitrate (many still frames are present), High quality, High Profile

Premiere Project Settings

- HDV 720p Preset
- 1280*720, 25fps
- No fields (Progressive scan)
- Video Rendering Setting: Maximum Bit Depth (unchecked), Optimize Stills (checked)

Movie Export Settings

- H.264
- 1280*720, 25fps
- Millions of Colours
- Quality 86% (don't understand!)
- Data Rate: Recompress - Always (checked) or Maintain Data Rate (unchecked) Limit Data Rate: (unavailable)

Keyframe and Rendering:

- Bit Depth: Use Project Settings (checked)/ 8-bit (unchecked)/ Maximum (unchecked)
- Fields: No Fields (Progressive Scan)/ Lower Field First (unchecked)/ Upper Field First (unchecked)
- De-interlace Video Footage (unchecked)
- Optimize Stills (checked).
