How to record 2 hours of DVD Quality Video in a 4.7 GB DVD?

[bugster]

Variable bitrates is not actaully supported and can send some players nutts .

What a pile of crap.

Variable bitrate video is part of the DVD standard. You are very unlikley to find any commercial DVD encoded using Constant bitrate video, it is just too limited.

Audio must be CBR, granted, but not video.

There's a lot of miss-information out on the web , and I have seen it all .

And written quite a lot of by the looks of it!

I was just wondering if all Australians are like this one - BJs who wrote this:

You are in breach of the forum rules and are being issued with a formal warning. No anti-Australia political-style comment, thanks.

You are going to have to lower your bitrate to get more video per disc. Reduce it to something like 5000 kbps and you'll get about 2 hours.

Yes! Or more accurately, a bitrate calc may suggest about 5200-5500k VBR. But 5000k is surely safe. Use a calc and try to get it as accurate as possible. This site has a bitrate calculator in the TOOLS section (menu on left), then search for the "bitrate calculator".

Or you can encode, author, then shrink with dvdshrink

No. A transcode is harmful to homemade video. It is only NOT harmful to most commercial DVDs because they use super-high bitrates with super-clean source.

There are commercial disks of high quality that have 2 hours or more on a single-sided single-layer disk.

Yes!

If you mean comparable to commercial dvd, you cannot. Here is the reason why, "This poses a problem when backing up pressed DVD-Video discs that can hold dual-layer worth of data per side, 8.5GB. " Commercial dvd is pressed not burned.

Not important. You can make excellent quality 2-hour videos on SL media.

Lower/compress audio - How much disk space can I save?

If using AC3 or MP2, none. Video occupies about 90%+ of the disc space. Do not use PCM, as it will then require about 25% of the disc space, stealing from the video.

Remember,: garbage in = garbage out

Yes! And shaky camera footage = garbage. There exist many anti-shake filters, Adobe Premiere Pro comes with a trial of one of them. Steadyhand is another one.

Hi, have you thought about KDVD? I haven't tried it myself, but supposedly you can fit up to 6 hours of Full D-1 720x480 on one DVD.

Absolutely not. Not suggested. Inferior quality output.

Follow Jimmalenko's (and others advice) advice. Encode using Variable BIT rate, compress the audio to mp2 224kbs (if in PAL land or your DVD player can handle it - not all NTSC players do) or 2.0 chan AC3 (all players can handle this). If the quality is not good enough after doing this, get a tripod!

Yes! That's worth repeating!

& if your young & don't mind wait for the rest of your life enable float piont presision (guess????)))

Your computer must be really old. Intel P4 systems have the option checked and it cannot be unchecked. It does not add any time, the hardware apparently supports this natively.

Now I am having an issue with my authoring software (Ulead MovieFactory 3), which report a duplication in the size of the project if I trim any portion of the video file encoded/compressed with TMGPEnc. Any ideas why this happen?

It's trying to re-encode. You need better authoring software that WILL NOT re-encode.

Of course that also assumes the MPEG encode you did was CORRECTLY done to the DVD-Video spec. Read the TMPG ENCODING GUIDE at www.digitalFAQ.com at look at the varying options. The only different you may want to make is the resolution (720x480 NTSC or 720x576 PAL) and bitrate of about 5500k VBR.

May I suggest you do something? Why not converting to Xvid?

Did you even read the question? XVID is not a DVD-Video format.

I have many titles here that hit 7 gigabytes , and after some alterations and using dvdshrink to bring the project down a little in size , they average between 3.9 and 4.3 . This is simply due to the fact I re-encode the audio to a lower bitrate . I strip all useles rubbish for the dvd's . I may re-encode the video , but not allways .I never , ever , use variable bitrate . Variable bitrates is not actaully supported and can send some players nutts . Everything is done in constant bitrate .
I have sent my discs to freinds , and all reports are its better than anything they have ever seen , even my vcd's beat disc's they have bought from others . I too have followed many guides here and on other sites , and what has been produced from some of the guides is complete and utter rubbish . I have done my own guides and given them to friends and guaranteed that if their video dosent come out in the same quality , I'll do the dvd compilation for them for free as a computer lesson . There's a lot of miss-information out on the web , and I have seen it all .

1- We are not talking about copying DVDs. We're making DVDs.
2- Lowering the bitrate on audio below 192k stereo sounds horrible.
3- Almost all commercial DVDs use VBR.
4- All DVD players are required to support the full DVD spec, including VBR.
5- I feel sorry for your friends, as everything you just gave was horrid advice. I suggest some more reading, starting with the www.DVDDemystified.com site.

My iLo DVD recorder in 2-hour mode

A DVD recorder is an excellent idea. The JVC, Pioneer and LiteOn/ILO units are all excellent suggestions instead of the computer method. These are pretty much dummy-proof (more or less, as long as you buy a good one).

And to the thread-starter: I hope you get it worked out, and were not too confused by all the bad advice that was given to you in this thread. I cringe when I see some of these things being told to people that are just starting out. You don't deserve all this confusion.

Good luck.

Why is it , I can fit 139+ minutes to a dvd-r , in extremely good quality , and it only takes up 4.1 gigabytes on the disc ???

You and your 4.1GB limit again ... what is with that ? <shakes head>

There's absolutely no problem whatsoever using up the full 4482MB - if anything, that 4.1GB mark is the cut-off when using crap media. If you can show me somewhere that mentions this 4.1GB as "the limit" for compliant DVDs, please provide a link ...

So DVDShrink to remove unneeded audio, OK. Re-encode audio - the only possible scenarios where this could gain you plenty of space is if the source is PCM or DTS - even a 448kbps 6ch AC3 re-encoded to 128kbps 2ch MP2 isn't gonna gain you that much space. And then 2ch @ 128kbps just sounds shite if you have a surround sound system. You do know that a re-encode of video is better quality-wise than using DVDShrink, don't you ?

I never , ever , use variable bitrate .

Variable bitrates is not actaully supported and can send some players nutts . Everything is done in constant bitrate .

Well, better through all those encoders that offer CQ and VBR modes out the window then!

... and don't forget to watch a commercial DVD in PowerDVD, with the "information" showing - you'll see the bitrate fluctuating all the time on DVDs of any significant length (over 90 minutes or so). Why ? Variable bitrate

If all you want to do is trim unwanted sections from your encoded video, then you might try Tmpg DVD author. It is easy to use for cutting and will not rencode. There is a setting in moviefactory to prevent rencoding, but I can't remember if it must rencode after triming.

Just for kicks, I did some sums:



Take note that I've been mighty generous and set audio to 0 kbps, so this is just the video ... and that's an awfully small bitrate IMO to be using CBR on Full D1, unless you're using Quarter D1, where it's overkill ... it's line-ball but probably OK for Half-D1 even ... to get "extremely good quality", that is ...

Thoughts, anyone ?

[smearbrick1]

I want to thank all of those who provided inputs to this topic.
I have been able to use TMPGEnco with Variable Bit Rate and fitting 2 hours of video in a single DVD with acceptable to good quality.

Now I am having an issue with my authoring software (Ulead MovieFactory 3), which report a duplication in the size of the project if I trim any portion of the video file encoded/compressed with TMGPEnc.

Any ideas why this happen?

Is this normal?

Should I edit or trimm video before compressing it with TMPGenc?

Rene

I'm sorry, but the guy who suggested converting to xvid should be shot! Can't you read, you half-wit!! The guy/girl doesn't want XVID... he/she wants DVD!!!

Sorry about that... now...

I think most would agree that you should do all of your editing prior to compression/conversion.
