captured 4/3 to 16/9

[cd090580]

Hi,

A friend of mine has capped for me a video of 15 minutes with resolution of 512*384 (so it's 4/3) My CPU is too slow so I can't capture it .

Now I've the file and open it with virtualdub. I notice that if I remove the black bars the picture format is now 2.35:1.

I'd like to encode it to dvd resolution (720*576) in 16/9 format. Is it better with such a resolution to encode it to FULL D1 or half D1.

The video codec is huffyuv so the source is quite good quality (capped from analog tv).

So what must the the final resize to put my video with correct aspect ratio
on my TV.

Source: 512*384 (4/3)
With black bars removed: 512*218
My final resolution: 720*576

So how much black bard do I need to add to put it on a 16/9 aspect ratio ?

Thanks.

You can use fitcd to calculate the black borders. I get it to 72 pixels borders top and bottom if you make it 16:9 anamorphic. You must use full d1 if you are gonna make 16:9, half d1 16:9 is not dvd compliant.

You'll get more vertical res if you encode at 16:9.. but be careful as it doesn't actually INCREASE the quality (just gives a bigger picture).

FITCD as Baldrick says is the way to go....and I'd make the VIDEO size between 640 and 688 horizontal.

Tip! Open the resulting .avs file in a media player first and check it looks OK before encoding.....it only takes seconds to check!

Thanks.

I've tested with fit CD.

But i've a new problem, when I try to play my avisynth script with Virtualdub or MediaPlayer I got a green screen. If I encore it I've also a green screen.

Here is my avisynth script (generated by fitcd):

# -= AviSynth v2.5.5.0 script by FitCD v1.2.4 =-
AVISource("d:\myvideo.avi",false)
Trim(2500,3000)
LanczosResize(688,432,6,84,500,216)
AddBorders(16,72,16,72)
AssumeFPS(25.000, true)
#Trim(0,487).FadeOut(150)

When I try to play or encode I've this screen:


The original avi plays fine in virtualdub.

What am I doing wrong ? I want to be sure the result is good before running the full encode to avoid waste lots of hours encoding the video.
