If you're producing a video for use in a PowerPoint presentation or any online use, realistically, you don't have to worry about PAL or NTSC. Those are really only considerations for broadcast--computers don't much care about frame size or field order.
If you're working with video as your source, match your sequence to the footage, and export a matching output file. In the PowerPoint or on a computer, it will work just fine. The laptop/computer and the projector will work just fine in concert, and the projector will simply show what the computer is feeding it.
So, when I go to make a Qt or H.264, there is still a choice for either NTSC or PAL, but you're saying that I can choose either one and it doesn't matter when someone plays it embedded in their PowerPoint presentation. Are laptops PAL or NTSC? My client has an NTSC he's using in Australia.
Don't choose "either one". Choose the one that matches the footage. That one will play fine on any computer, wherever the owner lives.
There is my confusion. I choose Export/Media, Format: H.264, the Basic Video Settings box only give you the two bullet point optons for TV Standard: NTSC or PAL. My sequence is Progressive. All the Preset choices seem to be either one of them too.
I think I have to approach it differently like I am writing in the following paragraph.....
That is another question I have between choosing Format: H.264 or Quicktime (which is what I really want).
I can choose Format: Quicktime, but all the Presets: are NTSC 720x480. But, I can choose a different Video Codec: Whatever I choose, the width/height stays at 720x480. So, then I change it to my Source setting which is 1280x720. When I select Field Type: Progressive, the Summary output: , the NTSC goes away. I guess that is what I want.
the two bullet point optons for TV Standard: NTSC or PAL. My sequence is Progressive.
So. Both NTSC and PAL, both in SD and in HD, can be either progressive or interlaced. One has nothing to do with the other. And you can modify any preset you start with if it doesn't exactly match what you need.
