Hey Mr Drew DVD authoring question

Drew

We spoke about it last year but just would like your thoughts on it again.

Cutting up the Ningaloo DVD and have been doing test encodes as we go along straight out of EDIUS. (1440/1080)

Encoded out 8.5mbps CBR mpeg 2 interlaced files, burnt to a DVD and played them on the computers and the SONY DVD player on the normal TV.

Then we encoded out progressive 8.5mbps CBR mpeg2 ones and burnt to a DVD and played them as well. The Progressive ones look real nice and seemed to play back fine, even on the sensitive SONY DVD player and cheap old TV.

Do you think if we replicated progressive ones that they would play fine in general DVD players or we could run into problems.

Cheers

Paul

i thought 8.5mb was too fast for most players except newer ones?!?!

9.8mbps is the max rate for the DVD standard, but 8mbps to play it safe as people with laptops that have bugs or to many programs runnig in the backgorund cannot handle the bitrate.

Funny we just put our old Ningaloo DVD on after watching the test encodes we are doing now...Man talk about quality difference... Pretty quick to encode out mpeg 2...1 min 20 secs takes about 4.20 to encode out with cc and effects from the 1440/1080 timeline. 4 to 1.

Anyhow I await Drews comments....

hmm, i always do 6 max to keep pace with the lowest common denominator. I figure most folks are using dvd players at least 4-5 years old...

Sorry didn't pay attention and never saw this question. Nobody calls me MR except my girlfriend

All DVD players should handle 8mbps easily, even computer DVD readers from the 90s.

Technically speaking, the progressive scan DVD players playback interlaced DVDs (which are the majority of all DVDs available publicly) as progressive using some form of deinterlacer. However, correct progressive flagging allows progressive material not to be interlaced and deinterlaced again.

Most progressive DVD authoring do it for 24P, so that people get the home theater feel. They have to flag it correctly for 3:2 pull down for none 24P players.

If your source is interlaced, I'd concentrate more on getting the color/gamma/contrast right rather than deinterlacing since the new machines do it anyways. Still progressive material, if flagged correctly, does playback better, as you've seen.

Most if not all SD DVDs produced commercially are interlaced for maximum compatibility with DVD players. I've not heard of a progressive scan DVD not being able to play on an older DVD player. But doesn't mean it can't or won't happen.

Cheers Drew

Well I think it will be progressive then @ 8 or 8.5 bitrate as even Kelly can see the difference when we compared them.

Thanks Professor Drew .

Have you tried it in 24P? Saves loads of space on the DVD. That's how they fit 2hr+ movies onto a single DL DVD.
