[Bobby Hall] “And how would I know if my computer has an eSATA port? “
Which mac do you have?

If you want to make a web video from a PAL movie:
– If the stuff is PAL 4×3: 768×576
– If 16×9: 1024×576.

[Anette Olsen] “But you wrote this: “Just putting the 1080P footage into a 1080i sequence will make it output in PSF”what did you mean by that then?”
I was just repeating Andrew’s text.
What John suggest is a very good idea.
With just a click, you flag the movie as Interlaced. No reprocessing.

Well, frame rate: 25fps.
The rest depending of the file size/quality you want.
Key-frames always AUTO, and down in the Video Options: Multipass.

[Anette Olsen] “I might try Rafaels suggestion of putting my progressive sequence into a interlaced sequence “
I haven’t suggested that.
Things are more simple.

[Andrew Rendell] “What do you mean by that ?
Digital video doesn’t have generation loss unless you process the pictures in some way, e.g., transcoding to a different codec.”
Well, you wrote: “Just putting the 1080P footage into a 1080i sequence will make it output in PSF”.
In that case the sequence will be rendered and, unless your 1080P master is Uncompressed and you process Uncompressed, the movie will be recompressed. One generation lost.[Andrew Rendell] “a couple of years ago I delivered a progressive file to a broadcaster and their playout screwed up the field order and caused a load of grief going backwards and forwards trying to apportion blame – “
if the file was Progressive, there is no way to mess up with the fields order.
it can be read as Progressive, Upper first or Lower First; Always will look progressive. Al the lines of any frame have been recorded at the same time. No motion difference between both field if read as Interlaced..

[Andrew Rendell] “Just putting the 1080P footage into a 1080i sequence will make it output in PSF (Progressive Segmented Frame) where the lines will be split into field one and field two. “
No need.
You will lose one generation.
If you just interpret the file as Interlaced, it will be read field by field instead of the whole frame at once.
As I said, the standard for 1920×1080 is interlaced, so whatever the file is Interlaced or progressive, it always be read/streamed field by field.
When your camera records 1080p, the SDI puts the picture out field by field this doesn’t change the Progressive nature of the picture, because both fields (upper and lower) have been generated at the same time. No between-frames motion.
Just give them the 1080p master. Their system will play it field by field.

The standard for 1920×1080 is always Interlaced. Progressive stuff is broadcasted/streamed as interlaced., so just send the movie as it is.
To make real interlaced from progressive stuff would take very long and will degrade de picture.

That’s with QT Player.
Just open the Export window (Cmd-E), and instead of selecting “Movie to Quick Time”, hit the “Options” button, and select “Movie to MPEG-4”.
In the pict you can see the QT Export window below the “Mpeg-4 Export Settings” window.

[Alexander Kallas] “I want to adjust all the separate clips in the sequence simultaneously.
Each clip has been rubber-banded to a greater or lessor extent.”
Then select the whole tracks and apply the RELATIVE gain option.
The rubber banding will be kept and gain will be added or reduced up to the value you set
