DVD Conversion 4:3 to 16:9

[wulf109]

Are there any DVD converters,transcode or encode,that allow you to crop the video from 4:3 to 16:9 ?
I make mp4's with Recode and it allows cropping to 16:9 during encodeing.

If you want to convert a 4:3 DVD to a 16:9 DVD then try DVD Rebuilder. Under the advanced options are the settings to do this.

Thanks,I'm trying it now. Does DVD Rebulder offer any way to control the output size. Ideally I would like to keep the original DL disk size,just do the 4:3 to 16:9.

[guns1inger]

DVD Rebuilder is aimed at the DVD9 to DVD5 market, but you can alter the settings to do DL size. It will also preserve menus etc.

The No Compression option doesn't seem to work with the 4:3 to 16:9 option. The result is in 4:3. It does work in DVD5 mode,the resulting DVD is now 16:9

The No Compression option doesn't seem to work with the 4:3 to 16:9 option.

If it gets filtered (crop and resize are filtering operations), it has to be reencoded.

If you want to reencode to DVD9 size, in the Options section of the REBUILDER.INI file, you might change the target sectors (which produces DVD5 sizes at the default setting) to TargetSectors=4050000. I think you'll have to add it as a new line because the default may not have a line in there. I'm getting my information from this post by the developer:

What is the correct script to resize a 640 x 352 avi? I have the following but Im in doubt if it is correct

BicubicResize(720,480,0,0.5)
AddBorders(0, 64, 0, 64)

When I preview in VirtualDub I get a 720 x 608 size? It is over a 4:3 ratio. What do I do?

[manono]

Use FitCD to get the correct Crop/Resize/AddBorders commands. In your case, if intending to encode as NTSC 16:9, a straight resize to 720x480 is good:

Lanczos4Resize(720,480)

[dannybz]

Then you are saying I should use the following: I am right?

LanczosResize(720,480)
AddBorders(0, 64, 0, 64)

I will test this when I get home this evening. I am at work.

[manono]

Then you are saying I should use the following: I am right?

LanczosResize(720,480)
AddBorders(0, 64, 0, 64)

I said no such thing. I said (for 16:9 encoding) just:

Lanczosresize(720,480)

Why, if you're making a DVD, would you use a non-compliant resolution like 720x608?

[dannybz]

Sorry for the misunderstanding, but I am not trying to make it a 720 x 608. I want to make a 720 x 480, but since the source is 640 x 352 and my TV is a 4:3 ratio what is the best resizing I should aim for?
I have always encode to 720 x 480 and watch them on my TV (4:3 aspect ratio). To what size should I encode this video and what script should I use?

I am currently using DirectShowSource, AddBorders and ConvertYUY2 ... and LanczosResize for this avi using CCE encoder.

[wulf109]

Tried the .ini file additions recommended by the link Manano suggested and it works very well. 4:3 to 16:9 conversion with DVD Rebuilder works with DVD9. I would not try to increase the sector setting as that might corrupt the layer-break setting.

[manono]

To what size should I encode this video and what script should I use?

I already told you ... twice.

I am currently using DirectShowSource...

AVISource is better:

AVISource("C:\Path\To\Movie.avi",False)#False Disables the audio
LanczosResize(720,480)#for 16:9 encoding
#LanczosResize(720,360)#for 4:3 encoding
#AddBorders(0,60,0,60)#for 4:3 encoding

[dannybz]

Manono, thanks for your great help. It works... I got the 720x480 size, but I have this other script that will also do the job. Which one will work better than the other and why? I don't want to distort the image.

LanczosResize(720,406)
AddBorders(0,37,0,37)

OR WHAT ABOUT THIS... If I am really dumb to use BicubicResize

BicubicResize(720,480,0,0.5) or LanczosResize(720,480)
AddBorders(0, 0, 0, 0)

[manono]

I already gave you the 2 scripts, one for 16:9 encoding and the other for 4:3 encoding in CCE. Don't ever use odd numbers for the crops, resizes, or addborders when the source is YV12. Use BicubicResize if you like. Here's the FitCD pic for 4:3 encoding of your 640x352 source AVI:
