16×9 to 3x4DVD back to 16×9
I am Broadcasting on a cable station everything that goes to “air” is MPEG 2
I have some DVDs from the Missouri Dept. of Conservation that are produced for broadcast television. They produce them in 16×9 and send them to broadcast stations for broadcast 3×4 with black top and bottom.
Our channel looks great on a wide screen that is set up improperly (which is most of them in my opinion) every other channel is stretched wide.
My predecessor at this job made this decision to air our channel this way. Our channel looks squeezed narrow on a 3×4 screen. I am thinking about changing this to match everyone else.
In the mean time I need to get this 3×4 DVD to a 16×9 mpeg without the black top and bottom. So far everything I have tried has not looked too good.

Tom, no matter what you do, your picture isn’t going to look the best.
Ideally, you want to avoid converting your DVD video to another format just to compress it down to Mpeg again, especially if you are going to be arking it.
If you want to remove 4:3 letterboxing from a video, you will lose about 25% quality straight off the bat, as all you can really do is scale the video to fit your 16:9 frame.I would have a look at Compressor and MPEG Streamclip, MPEGStreamclip to demux your DVD TS_Video files to a workable mpg format and then send it to Compressor. If i’m not mistake, Compressor will allow you to crop your image (which will remove the LB) and then allow you to re-scale it to the require SD 16:9 dimensions all without the need of transcoding to a different format first.
If you’d prefer to use FCP, then convert your DVD footage to a useable format using MpegStreamclip, and then scale the 4:3 Letterbox video to fit your 16:9 timeline, finally, output using Compressor to your required Mpeg format. You might get a slight quality boost if you set your FCP sequence settings to high and maybe add a sharpen filter.
On the whole though, I’d expect the video to come out looking quite soft regardless of the method you use. Hope this helps.
All the best,

I tried to just convert it to Mpeg with Streamclip. I got a good looking result in 3×4. When i tried to send it to my program server it was not recognized by the scheduling part of the software. I figured that the server would not really care what aspect the video was in but it seemed to. I chose convert to MPeg and i did not get any audio. I chose convert to mpeg with mp2 audio and that looked good but did not play on my server. Would convert to headed mpeg do me any good
I would not really need to convert this and remove the top and bottom if t would play out on our server.

You will need to get the required specs for the MPEG-2 encoding used by the broadcast server. MPEG-2 transport streams are not the same as MPEG-2 video files used for DVD. Compressor can create MPEG-2 transport streams, but you’ll need to know the required specs first.

READ THE MANUAL DUMMY
I checked out the broadcast server manual and It said I could import a videoTS folder and it would convert it for me…….
Well I’ll be!!!!!!
