PAL to NTSC or AVI to Mpeg, What's My Priority?

    I notice this file is PAL. Does it matter if I just code to Mpeg with a default NTSC setting(I think there's a program out there). Or convert to NTSC manually then to Mpeg.

    There might be some other tweaks to the frames or BPS that i'm too new to see, If someone can chime in with advice, that'd be stellar...

    Here's the Specs:

    Size : 695 mb
    Video Type : Mpeg4
    TV Standard : PAL
    Resolution : 640x272
    Total Bitrate: 830 kbps
    Audio Type : MP3
    Sample Rate : 44,100
    Audio Bitrate: 135 kbps
    Duration : 01:57:07.4

    Converting this AVI to Mpeg puts it at about 5.26GB. That's quite a change from about 1GB.

    I hope to do this correctly the first time...

    Any help is appreciated THX!

    If its for the internet it you might get issues with the frame rate conversion from PAL to NTSC. But it should play reasonably fine, maybe some stutter here and there. Try keeping the frame rate to 25fps if there is a setting that allows this. If you intend to play it back on a television then it must be PAL for PAL tv's.

    tell the reason why do you want to do this? its quite strange that "pal2ntsc or avi2mpg". most hw players can play any kind of variations on any kind of tvs. you can try download virtualdub and then change framerate (actually it will be just re-fraiming. so say your movie 1hour with 25 fps = 60 min * 60 sec * 25fps = 90000 frames.
    90k frames /29.97 (ntsc fr) /60 = 50 mins. so your movie will play a little bit faster. then you need squiz audio as well.

    for mpeg2 you need set 2mbits rate and resolution say 360x480 and convert it. with 2mbits for 2 hrs you will get about 1.8 gb file

    Thanks for the heads up Deesy! I don't want to take a chance that the video and audio will work properly in my stand alone player. DL DVD's are about $20 for 15 and you can blow that out in one evening...

    I'm getting expert advice from the boards and it's better to use someone elses smarts than to test my ignorant theories on my wallet. I've got VDubMod to take it apart with and ffmpeggui to convert the audio. I'll let you know how it goes on this thread. Thanks again for the info!
