Export as a Quicktime Movie using current settings not as a Quicktime conversion. Do NOT re-compress your movie, especially to another codec.
This subject has been covered quite a few times in this forum.

Exactly the same problems or similar?
Have you tried to play these back using the latest version of VLC?
If you are viewing in Quicktime player can you step through frame by frame and see every single frame through the problem areas?
Just for the sake if it can you try and encode at 320×180 @ 300Kb/s

I’d say that your data rate was WAY too high for the 864×480 frame size and even too high for the 1280×720.
What keyframe setting are you using?
What kind of content is it?
Try 832×468 at 1.2Mb/s keyframe every 10 seconds or 300 frames

So, to say what I meant with uncompressed we have to say “lossless”.
Well then you have visually lossless or mathematically lossless!

You’re not doing anythingwrong.
Uncompressed means different things to different people.
4:2:2 is compressed colour space when compared to 4:4:4.
10 bit is compressed when compared to 16 bit.
Even the None codec is ‘only’ 8 bit

You don’t say what you want to deliver, or to whom?
Is it for web delivery, IPTV, Broadcast transmission or mobile device?
Just so you know, HDV uses non-square pixels to deliver a 16:9 image so 1440×1080 non-square pixels equals 1920×1080 square pixels.
1440/1080 = 1.333:1 or 4:3 – Rectangular pixels
1920/1080 = 1.777:1 or 16:9 – Square pixels
Bottom line is that 1440×1080 is HDV’s way of ‘cheating’ 16:9 Full HD video.

I generally use Quicktime Pro for this when necessary and I’m not sure there’s an option in the GUI of ffmpegX to do it – you could try asking/searching in the ffmpegX forum here:

Yes.
If you have the money get Episode with the Flash add on, it’s the best out there.
Next best is compressor
If you want it for free get FFMPEGx.All I think are better than the Adobe solution

The file size is in direct relation to the actual data rate of the file multiplied by it’s length. Bear in mind that although you specified a data rate of 450k/s, it won’t remain at exactly that throughout the clip.
