MainConcept or Graphedit and resize with black bars

[BCIcdrz]

I need to resize a 576(or so)x306 to dvd size (720x48) but the videos 4:3 ratio brinks it to 720x380. how do I add the black bars to the video? I like MainConcept Mpeg encoder 1.3 or graphedit. TMPGenc takes like 10 hours to do it.

You can use a frameserver to do the resizing with black borders, AVISYNTH or VIRTUALDUB will work, though avisynth can feed faster than vdub.

With AVISYNTH use
BicubicResize(720,380,0.0,0.6)
AddBorders(0,50,0,50)

With VirtualDUB use the built-in RESIZE filter with settings
New Width: 720
New Height: 380
Filter Mode: Bicubic
Tick 'Expand frame and letterbox image'
Frame Width: 720
Frame Height: 480

Excuse my ignorance bunyip,

But it looks like your reply will be the answer to my prayers with Mainconcept.

I'm creating SVCDs with mainconcept, but if the source is wide screen, it gets coded 4:3, so you get that stretched look in the SVCD.
There is no "keep aspect ration" in Mainconcept.

I downloaded and installed AVISYNTH 2.07, but I don't knw how to use it.
It appears like it needs to be a plug in for Mainconcept ? Not a stand-alone app.
Could you tell me how to apply it.

I assume for a PAL compliant SVCD, the settings would be
BicubicResize(480,576,0.0,0.6)
AddBorders(0,50,0,50)

Thanks

Please help

To use AVISYTH you just need to create an 'AVS' file with the settings you require.

Use a text editor e.g Notepad and enter following text;

(Note: this is for your Jolo's PAL settings)

(Change this line to point to where your dll file is)
LoadPlugin("E:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec 2.dll")
(Change this line to point to your input AVI file)
AVIsource("your.avi")
ConvertToYUY2()
(Change this line so that XXX = the height of the actual video e.g if the AVI is 704x300 then XXX=300)
BicubicResize(480,XXX,0.0,0.6)
(Change this line to 'pad' the video out to 576 e.g. if the above XXX=300 then set top & bottom to 138)
AddBorders(0,top,0,bottom)

Save the text file as something like 'video.avs'.

In Mainconcept when you select 'open video file' select 'file types' of 'all files' and open the 'video.avs' file.

Now render in the usual way.

Bunnyzip,

I can't wait to try it !!

Thanks jolo - it's easy to be nice when you live down here - something to do with being upside down all the time. (By the way he tag is 'bunyip' but you need to be aussie to know what a bunyip is.)

I've had a re-think about how to keep the aspect ratio intact for SVCD since it is encoded at a ratio of 1:1.2 but playback is at a ratio of 4:3.

If you apply the following formula to calculate the value of 'XXX' in the above post you should retain the original ratio.

H = height of the original AVI
W= width of the original AVI

XXX = (( H x 1.334 ) / W ) x 576

in the example this would make XXX = 327 which is a better result.

I've got myself in a little trouble with my script. Duh.

Here is my script, and when I read it in, things kind of ...... broke.

The program stopped, etc. As you can see, I'm trying to convert an old Monty Python movie. I've never done this before, so do you anything wrong. The 688,368 I got from opening up the avi in Vdub.

LoadPlugin("C:\Program Files\AviSynth2\plugins\MPEG2DEC2.dll")
AVIsource("D:\Documents\My Videos\Comedy\meaning_of_life.avi")
ConvertToYUY2()
BicubicResize(688,368,0.0,0.6)
AddBorders(0,top,0,bottom)

I'm waiting for my ticket to come to Australia. Where is it you live. I live in Colorado Springs, Colorado, where the rocky mountains are. It is snowing out as I right this.

Thanks,

Jon

SNOW? I've read about that somewhere. - Currently Sydney based, but may be going rural soon.

The thing you have missed in the script is that the 'Resize' and 'Addborders' together have to add up to '480 x 576' for PAL SVCD. (you didn't change the addborder settings).

So using the formula above the settings should be this;

BicubicResize(480,410,0.0,0.6)
AddBorders(0,83,0,83)

If you still have problems - try the VirtualDub solution.

[jolo]

Thanks.

If I still have trouble, I will bomb someone. That's the way we handle things here in the land of the "BUSHman".

[BCIcdrz]

is there a filter compatable with graphedit that will do this?

[jolo]

bunyip,

You are the best. Made the changes and it led me to understand the process. It worked like a charm in mainconcept.

If you don't mind, I am sharing you genius with some people on the Mainconcept forum.

Have a beer on me mate !!
