For this conversion, we will be using FlasKMPEG, Avisynth, and TMPGEnc. Make sure you install them all properly. First you will need to start up FlasKMPEG and import your source PAL video by choosing File --> Open Media.
Now we will setup all of our settings in FlasK. Go to Options --> Select Output Format and choose Link to Avisynth 1.0BetaXX.
Now go to Options --> Output Format Options and make sure the create avs file is checked. Now that those simple options are out of the way, we need to tell flask how to process our source video. Go to Options --> Global Project Options.
Now under the Video Tab, choose the following settings:
Under the Audio Tab, choose the following settings:
The Post Processing settings are your choice and the Files settings are not needed for the Avisynth plugin (which we set up earlier). Under the General Tab however, we need to tell FlasK how much of the file to process. Checking the Compile Whole File option WILL NOT WORK!
For MPEG-1, just open the file in VirtualDub and check the video's attributes by going File --> File Information. Now just take the # of Frames and put that number in the Time to Compile in FlaskMPEG.
MPEG-2 is a little trickier. I can't think of any program I've used that gives the exact # of frames for an MPEG-2 video. If anyone knows one, please let me know. So for now, just take the time of your video, i.e 4:26 (4 minutes, 26 seconds), and convert that to all seconds format. As an example:
This video = 4min, 26sec
4min = 240sec (1min = 60sec, so 4min x 60sec = 240sec)
240sec + 26sec = 266sec
So, This 4:26 video is 266 seconds long. Just plug that number into the Compiling Time box and be sure to choose Seconds as the time base.
Now, click OK and choose Run... --> Start Conversion. You should see this screen.
Now, minimize FlasK. DO NOT CLOSE FlasK!. Start up TMPGEnc. Avisynth should've created an AVS file in the root of your hard drive. Load this file in TMPGEnc as you would normally load any AVI video file.
Choose your SVCD NTSC profile and encode the file. You now have an NTSC video file!
