MPEG IMX 625/50 (50mb) Compression for Broadcast TV. After compressing the video per specs for network. Visible scan lines appear in 3 clips.

I believe that frame size they sent is incorrect. I have been going through the settings and when I set the codec at MPEG IMX 625/50 (50MB/S) and it automatically goes to the 720 x 576 frame size.

These were the settings from first video file compressed that didn't have any visible scan lines.

Now the next image below is another screen shot of the new compressed file that has the visible lines. I hade to make the 4 channel change in the audio settings that I didn't do the first time.

MTV already recieve the first file I sent them and it was fine. I am now trying to send them a updated file with the corrections on the edit and 4 channel audio, but am getting these scan lines. grrrrrrrrr

Video with no scan lines below

OK, I went back and imported both MPEG IMX 625/50 (50mb) files into compressor and looked at the inspector for each file. The video with out the scanlines that I already sent is below:

The video with the scanlines inspector reads:

So the difference is the NATIVE FIELD DOMINANCE, BUT THEY REQUESTED UPPER/TOP FIRST.

Is it really that big of a difference. I'd rather send them a clean file with out the scan lines. Does the system get rid of those scanlines? Also, does it matter on the format being a H.264 or SD 8-bit Uncompressed NTSC?

I am in the middle of compressing again, but would love some input back.

These apple community forums are very appreaciated.

This is what they sent me. So those lines wont appear when they import into their system. They didn't say anything about progressive or interlaced.
