half-d1 question

[chobo321321]

I was just wondering how can I make half-d1 resolutions (352x480) take up the whole screen of a regular TV?

I'm just asking this because I made a test DVD with lots of different resolutions, and when I used the half-d1 resolutions (NTSC) the image did not take up the whole screen. It appeared to be centered with tons of padding around all the sides. The source resolution of the file was 640x480, and it was just for test purposes. I know vcd, and some svcd's are around the resolution of half-d1, and the image takes up the whole TV screen when coverted to those formats, but shouldn't the image take up the whole screen of a TV if you convert a file to half-d1 resolutions in mpeg-2 format?

Any help is appreciated.

Your settings are wrong, obviously. Your player should resize automatically. Are you using TMPGEnc? If I were you, I'd make a short clip. Then load and open the DVD template, unlock, change to 352x480, save as Half D1 template. (Change NOTHING else). Try it, if the DVD template worked, so will the new one. Then you can unlock to adjust bitrate for a full encode.

Or you could just use DVDRebuilder and not have to fiddle with it. DVDRB has a half D1 option.

Good luck, you'll work it out.

I use both tmpgenc 2.5 plus, and CCE sp 2.5. For my test DVD I used CCE sp to do the encoding. Here is the avs script I used.


AVISource("test.avi", False)
LanczosResize(352,480)
ConvertToYUY2()
AddAudio()

Hmmm, I'm just starting to learn how to write scripts myself, sorry. TMPGEnc is certainly easier. :P

A few weeks back I was struggling with getting the correct aspect ratio when converting an AVI with CCE. Finally succeeded, then office work got too hectic and damn, I've just about forgotten what I did! Have to pick it up again when I get some spare time...

Hope you work it out or someone else responds.

Did you download the file? If so, it may be that the source file is not what you are thinking it is.

[chobo321321]

The source file is 624x336 I have already encoded it to DVD, and it runs perfectly fine using the following script

AVISource("joined.avi", False)
LanczosResize(720,460)
AddBorders(0,10,0,10)
ConvertToYUY2()
AddAudio()

I just wanted to see if resizing the video to 352x480 would take up the whole TV screen, but it looks like a little box surrounded by padding from all sides. I was under the impression that resizing it to this size that the image would still take up the whole TV screen.

Thanks for the help so far, I'm kinda lost on this issue.

If I resize a 624x336 encode to 352x480 should the resulting image take up the fullscreen of a regular TV, or should it be small, and padded?

I resize all my captures to 352x480 and they work just fine. Taken from vcr tapes of tv, I see no loss of quality compared to 740x480. Nyah Levi

CCE will always encode to 720x480 unless you uncheck DVD VIDEO COMPLIANT under video settings.
You resized correctly in avisynth, but CCE is padding it back to 720x480.

Try unchecking it and do a test encode.

[chobo321321]

Thanks BSR! I apparently had that checked in CCE SP. I usually leave it off, but I made a new template, and forgot to uncheck it. I had no idea that CCE would still resize to 720x480 with that option checked. I thought it had something to do with the bitrate being 9800.

I thought it had something to do with the bitrate being 9800.

Yes I think it has something to do with that also.
