“interlaced lines” appear on DVD … how to get high qual out of Premiere CS3?

[Mike Velte]

Both Encore and Premiere have the same encoder, so it does not make much sense to export an uncompressed video for Encore.
Interlaced lines will show up a progressive scan PC monitor. If your DVD is for viewing on a PC, then deinterlace on export from Premiere.

Thanks for the response.

I am only noticing the interlaced lines on my PC when I go through my workflow using the CS3 programs. When I do it with the APP 1.5 and Encore 2.0, the resulting DVD as played on my PC does not have these lines visible…something somehow is different between the too.

I wish to export in this uncompressed format b/c I am also going to use the same file to save to other formats, including to tape.

However, what format would be ideal to export to Encore? Obvious the highest quality is my desire.

[Derek Beck] “However, what format would be ideal to export to Encore? Obvious the highest quality is my desire.”

Export from Pro as elementary streams Mpeg2 DVD and .wav. Encore will encode the audio as Dolby and not reincode your .m2v file.

[Derek Beck]

What settings do I want for the highest quality MPEG2 streams? Do I risk too much bit rate with this manual process? I’m presently using auto transcode within Encore.

[Mike Velte]

The Auto settings in Encore often leave empty space on the disc that could be used for a higher bitrate/quality.
A couple of guidelines I use;
1.Dont exceed 8 mbps video bitrate.
2. Fill up the disc with the highest video bitrate without voiding #1.
3. 2 Pass VBR for movies over 75 minutes.

Calculating bitrate involves a bit of math. The number of seconds in your movie times the the number of video bits per second and then divided by 8 to convert to Bytes should be close to 4 GB.

Since my product is just 23 minutes, I set it to CBR 8 Mbps…but Encore claimed the bitrate is too high. Should I go down to 7 Mbps, or is there a way to find a sweet spot between 7 and 8 that Encore will accept. (And why does Encore balk at what should be a constant 8 Mbps?)

Thanks again,
Derek

I’ve just re-encoded in APP CS3 as a mpeg2 elemental files (no multiplexing), CBR set at 7Mbps (and PCM audio for the audio file…I apparently don’t have the Surecode Dolby codec).

Despite this, Encore CS3 still claims the bitrate for the movie timeline is too big.

I don’t get it…any thoughts?

[Mike Velte]

Open a new project in Encore and click the Advanced tab of the New Project window. Does that give you any clues?

[Derek Beck]

The project settings advanced tab are: automatic transcoding: 7.0 Mbps, audio transcoding: PCM.

I’ve exported it yet again, and this time at VBR (1 pass), with min of 4, target of 6, max of 8 Mbps. The DVD check completes fine now in Encore, but upon build I get the following error:

PGC “Movie” has an error at 00;23;27;28. The data rat of this file is too high for DVD. You must replace the file with one of a lower data rate. -PGC Info: name=movie, ref=Xpgc, time=00:23:27:28

Then it stops. By the way: that time code is seconds from the end of the credits…I wonder if it times with a logo in the end of the credits…

This is driving me nuts. I really appreciate your help though!

Export the credits as DV.avi. Then overlay that clip on your timeline and export your movie as mpeg again.
There is something causing a spike in the bitrate at the end.
