Best Setting for a 90 Minute DVD feature export???

[Omar67]

Hello,

I am new to the board. I have a 90 minute HD feature film that i am trying to put on NTSC DVD. I had compressed the original file (from 100 GB) through Soreson Squeeze for an NTSC DVD authoring. The squeezed file ended up being 5.20 gigs. This is too big to burn at "high" quality on MovieFactory. I read you can change the compression under custom settings for export. I have tried different compressions (6900 k bits and Quality 90 etc.) which converts the file into a 3.88 GB file. but i am wondering if anyone has the ABSOLUTE BEST way to take a 90 minute file and convert it to the highest GB (close to 4.30 gb) with the best viual results. Shot i set the quality at 100 and lower the K bits?

Also is that correct a 90? or should i always go to 100. This is a screener that i want to send out - so the quality has the best

thanx,
Omar

Here's an online Bitrate Calculator.

(6900 k bits and Quality 90 etc.) which converts the file into a 3.88 GB file

Actually, that's not bad. You probably won't notice any difference of you make it exactly fit the DVD. 5500 to 6000kbps is "typical" for commercial DVDs. But, I suppose that it's not so great compared to high-def

Also is that correct a 90? or should i always go to 100.

Setting it to 100% will NOT make your file bigger*. (Everybody gets confused by this...) That setting determines how much time the MPEG encoder takes to encode the file. Setting it to 100 will give you the best quality Ulead's encoder is capable of at at given bitrate.

You can also try DVDshrink. You feed DVDshrink the already-authored DVD structure (i.e. the AUDIO_TS and VIDEO_TS folders) and it squeezes it to exactly fit a single-layer or dual-layer DVD. I don't really like the idea of going through a 2nd lossy encoding step, but DVDshrink seems to do a very good job. (I haven't done any scientific experiments.) You'll have to search the Net for DVDshrink though. You can no-longer download it from the official web site. (It has some unadvertised features that make it illegal here in the USA under the DMCA.)


* The filesize is determined ONLY by the combined audio & video bitrate and the playing time. You can scale-up kilobits per second to megabytes per hour.

Is that CBR or VBR, and does that include audio The actual AVERAGE bitrate must be alot lower than 6900kbps to get the results you are seeing...

Just to add to this -- there's a little more involved when dealing with multiple audio tracks and multiple video angles (that's not to say those features are available in MovieFactory).

I used VBR both in Soreson Squeeze and in DVD MovieFactory. Should i use CBR instead on both compressions for the best version?

What audio type/bitrate are you using

When encoding in Sorenson using VBR, how many bitrates does it allow you to specify, and what are they called -- look for something like Minimum, Average, Maximum

The 6900kbps you specified was NOT a CBR bitrate -- if it was, you wouldn't have ended up with a filesize of 3.88gb for a 90-minute video (including audio it would have been too large to fit on a DVD5 disc).
