avi pal to ntsc dvd

[bigfatbob]

I recently try several program to make Dvd from some Pal video. I will use Dvd-Lab pro 2 for authoring the dvd. But I have some problem converting those video from avi to dvd format. All the program I tried stretch video to an 4:3 aspect ratio. Those video all have a resolution of 480x272 ... What program and which settings should I use to convert those video to dvd format with an aspect ratio of 16:9 .. or anything with a black border on top and bottom and who can be played on ntsc dvd player. Thanks.

what encoder are you using? Whatever it is you should set it to encode as 16:9. 480x272 = 1.76, so it's not that far off from 16:9 and could be bearable for you when converting to DVD. But to get an accurate resizing you can use the user-friendly fitcd that will generate an avisynth script, and you can import that script into your encoder if it supports it.

There are a few tutorials here for converting PAL to NTSC.

The method that works very well for me is:

1. Determine the length of the video using GSpot.

2. Calculate your required bitrate using VideoCalc. I usually set it for 200 MB of authoring overhead for menus and music

3. Encode the video to MPG2 using TMPGEnc at a resolution of 720x480 with an aspect ratio of 16:9, noninterlaced, 25fps, and the bitrate calculated by VideoCalc, set audio as WAV audio, encode video and audio as seperate elementary streams.

4. Convert the WAV audio file to AC3 using AftenGUI using the audio bitrate that you chose in VideoCalc.

5. Load the video m2v file into DGPulldown, check the box 25->29.97 fps and click convert.

6. Load the AC3 audio and the new pulldown m2v file into DVDLab and author as usual.

7. Burn the DVD using ImgBurn.

That's the simple method. I usually convert the audio to WAV first by using VirtualDubMod, clean it up a bit if I need to in GoldWave, save as 48000 Hz WAV, then convert with AftenGUI. I load the audio into an AVISynth script that I have that cleans the video a bit using the Convolution3D filter, crops the edges a bit and adds black borders for the same amount that I cropped out, then performs a Lanczos Resize to 720x480 and converts the video to the RGB colorspace. I then feed the AVS file into TMPGEnc and follow the steps above.

This is just a quick rundown and should help you get started. Look for the complete tutorial here.

Also, all of these tools are available in the tools section here.

Good Luck,
Lloyd

Sound process, well proven and generally produces the best output. Other methods tend to produce jerky zooms and pans or audio sync issues.
