What is the best way to put the most HD content on a DVD
I have captured HD Mpegs from my Sony HC3 and they are in mpeg-2 format. When I burn them to a dvd in HD format what is the best way to reduce the filesize so I can put more content on a dvd? It is normally at 25,000 bit rate, can I lower that and still keep same quality or what is the best idea? Thanks...
gigabyte137,
There aren't ideas, only facts.
Lower the bit-rate of an mpeg file reduces quality, how much loss depends on how high the quality of the source video. The video is also re-encoded which introduces some loss. I've re-encoded hd-mpeg2 a few times and it still looks acceptable.
Many compression methods can be used.
HD-Divx - commercial product.
AVC/H264 - New HighDef Standard
I would select to use the AVCHD Disk (h264 video) method. AVCHD Disks have menus, chapters same as dvd's do. These disks playback on the computer using Nero 7/8, Powerdvd7, Windvd 8. Blu-Ray Disc players including the PS3. This is done using Standard DVD's or Blu-Ray Disks.
This is actually a new standard so your safe using it. You can buy & install a HD-Addon pack for MF6+ which will allow you to encode to this standard.
I encode the mpeg2 video files from my Sony HC3 using this add-on pack. The encoding parameters I use are Dolby Audio 5.1@448kbs, 18MBS VBR max. After converting the videos they end up with an approx average bit-rate of 11-12MBS. This will more than double the capacity for a single layered dvd compared to using HDV@25MBS in Mpeg2 format..
The video quality is excellent, same as the source video.

No, HDV is 1440x1080. the bit-rate is what affects the quality.
As long as you don't change the frame-size you shouldn't lose to much quality.
HD is pretty flexible though, even re-encoding to 1920x1080 once doesn't make to much quality loss on my system.
As far as displaying the correct framesize or full screen shouldn't be a problem on the Toshiba players. Many playback devices have a selection method on how to display the video back.
Usually the default is to play full screen. So even if your source videos are xyz the Toshiba HD-DVD player will display the video full screen depending on the display mode.
Do a test and change the Toshiba's display size to 480P or 1280P. Then playback one of your 1440x1080 HD-DVD's. In 480i/p/1280p the Toshiba will display a 1440x1080 or any HDV Compliant signal to full screen to match the present connected "Display Mode"
I've used my Toshiba player connected to a Standard TV ( 480i ), playsback the HighDef just fine.
What makes video confusing is PAR versus FrameSize specs.
Mpeg Pixels are the compressed video information.
They have whats called a PAR (Pixel Aspect Ratio).
So starting with a square box (square pixel box)
720x480 4:3 uses a PAR = .9091
720x480 16:9 uses a PAR = 1.2121 (Also in ulead known as Non-Square Pixels)
1280x720 uses Square Pixels, this is known as PAR 1.0
1440x1080 uses Non-Square Pixeels, PAR = 1.3333
1920x1080 uses Square Pixels, PAR = 1.0
Your playback device should format the picture to match it's connected "Display Mode"
In MF6+ if you want to re-encode down to 18MBS I suggest creating a template first, then Export -> Use your custom template.
I've been seeing more Ultra-Divx certified dvd players around. In the US they are about $99.00 dollars. HD-Divx looks great and uses 8MBS, so you can get 1 hour on a single layer dvd, 2 hrs on a DL Dvd.

Well Toni if I keep the mpeg-2 HD video from my HC3 and use Moviefactory to make hd dvd's and keep the 25mbps they look perfect on my Toshiba HD-A2 player.... If I change the bit rate to 18mbps I see artifacting and jittery in my HD-A2 player. It cut the filesize from 1.6 gigs to 1.2 but no worth the picture degredation... Maybe I will look into a bluRay player and make avchd as I didnt see much difference in them when I played on my computer compared to the original and it was about 40 percent of the original...
Gigabyte,
Did you make a template to re-encode to 18MBS and keep the fielding correct?
Sounds like a bad conversion if the player was pausing, or a bad burn. This is one reason I started getting away from 25MBS on Dvd's. They have to spin fast and at 3X mode.
If you have the HD-Add-On pack I posted how to make avc/h264 videos from your 25MBS videos. I cannot really see a difference in the quality. They are excellent.
I have posted how to do this before with more details.
Start a AVCHD project.
You make a template up first under the disk template manager (always double check all the settings). Then under the Gear Icon change the project settings to that new template.
Load your mpeg2 videos, click on the export icon -> select your template and create the avc/h264 videos. Then remove your mpeg2 files from the timeline, insert the avc/h264 video which are compliant. Make a menu and burn the dvd.
When you make the template you use the same settings and in the original mpeg2 file except I've found using 18MBS Variable bit Rate with Dolby 5.1 @ 448kbs works great. The videos end up with an average of 11MBS.
So the difference in the for the avc/h264 template would be the video bit rate compared to the mpeg2 video along with using Dolby Audio (the audio is really your own preference).
Going into the burning module with avc/h264 compliant files makes the process go much faster. You can also perform multiple encodes to H264 by highlighting which videos to convert (hold down the left CTRL key and select each one with the mouse). Then when exporting these files will be individually encoded.
I use a Sony Playstation 3 (PS3) to pllayback these disks, also the 25MBS mpeg2 videos in file mode or streaming from a server.
I'd like to point out that with the AVCHD disks that later on you can re-use these videos. Either re-import them back to your harddisk using MF6+ or if running Vista copy them from the avchd disk back to your harddrive. They are already compliant so your just load them back into a new project and burn the new avchd disk.

I did notate in my post that I did create avchd disk and there was no difference in the picture quality on my computer but I dont have a ps3... The 18mbps wasnt jittery that much it was just distorted meaning pixelation and yes I created a new template when I did it...
All in all if I am going to burn HD content on a dvd then I will keep 25mbps and if I get a Bluray player in future then I will make avchd disks....

I'll mention one last point of interest.
To playback AVCHD Disks on a computer, a PCI-e 16x video card with hardware acceleration is necessary for proper decoding & de-interlacing. Along with the video card is the correct playback software that uses the video cards acceleration features.
PowerDVD7 Ultra supplies a codec and uses the ATI's AVIVO High Definition acceleration. Nero appears to me to use the DirectX acceleration.
My computer uses 1% cpu power when playing back AVCHD videos (file playback). A little more cpu usage if playing back in the avchd disk mode.
ATI uses AVIVO for HD acceleration
NVidia uses "PureVision or PureView" for HD acceleration
So even when you have the correct video card for proper HD playback (Blu-Ray or HD-DVD) you still need the correct playback software to correctly access the video cards hardware acceleration features.
Toshiba HD-DVD also uses AVC/H264, but it has to be on a HD-DVD. Nero calls it AVC for HD-DVD. For some reason Nero wants to make/create very high bit-rates when encoding these video for HD-DVD on real HD-DVD's (I don't have a HD-DVD burner). I made some on dvd and the Toshiba's player said not the correct format for this media.
