Why the black edge on top and bottom?
I am trying to get the highest quality video from FCP to FLV to fit the flash player that the web designer told me. Changing the framing of the player is out of the question because I have tried that route many times and they won’t.
The FLV player is set to 643×362 which is a 16×9 frame, ratio 1.78. However, my source material is all over the place, so I have to conform everything. Some footage is animation that I made in a 16×9 frame, some is 16×9 HD footage, and other is letterbox SD fotage. I’ve put links below with each case. I’ve been at it for the whole weekend and can’t come with a solution. They really want the video to fill in the whole flash player and told me to just zoom in on the video to get rid of the black on the tops, but I feel that is changing the pixels aspect ratio and the image looks strange.
So got some links for you to take quick peaks:
Case#1:
– Video/Animation that I did in Motion at 960×720,pixel aspect ration of 1.33, Field Order Lower First (even) @ 29.97fps
– exported the QT and did tried two things, but the one that looked the best has this workflow: import the animation clip into FCP, then export out using QT Conversion to the player setting size. After that put that clip into Adobe Media Encoder. Text looks pretty sharp, some video is eh…But fills up the whole player.See here:

Case#2:
This footage is HD, so it is already natively 16×9. Shot on that Sony, cut with the other animation that I had created. Exported using the the same QT Conversion and run through media encoder. End result, black along the edges.See here:
https://www.episcopalchurch.org/JWPlayerDemo/flow/Katherine2.htmlSettings I put: Dimensions 643×362, preserve aspect ratio using letterbox if necessary because “crop” which is no good with the lower thirds and the FitWithin, just messes up the pixels period.
When I export the native QT into compressor, I set up a droplet to the specs, but doesn’t looks so sharp.
See Here:
https://www.episcopalchurch.org/JWPlayerDemo/flow/Katherine.htmlCase#3
Now we have to deal with the SD footage with the letterbox. Same issue, but black edges a bit more than the HD footage.See here:

Thanks to whoever can answer this.
Also I use Adobe Media Encoder on my Mac Pro Tower using Leopard.

Generally I’d avoid odd numbers in frame size. You could crop some of those.
16 doesn’t go into 643 evenly either.
See this from Adobe.

Yes, I thought so. I was trying to explain to the web developer guy that it has to be divisible by 8 because I thought that the dimensions seem wrong but he said he used this aspect ratio conversion thing to give him those values. It’s here:

What should I tell him?
Thanks

That aspect ratio calculator has nothing to do with how compression codecs work. A mathematically correct aspect ratio may be mathematically incorrect for the codec.
Send him the Adobe aspect ratio link and let him know that Adobe engineers have posted it as their Flash aspect ratio specs.

Thanks…in the beginning, I was telling him that my recommendation was 768×432 but he said it would off balance his webdesign. I told him photoshop and video work differently because of the scanning lines, etc…but his head was spinning.
Not much to a design if you got crappy video as the focal part of the site.
I’ll battle it out again. I’m still peeved about the 4 different cameras for the next two weeks.
