  1. I'm sorry, I know this sort of question is asked a lot, but I never seen a concise answer to it.

    I have some animations of mine in PAL (720x576 @25fps), and have been asked to convert them to play on NTSC.

    What is the best way to go about this?

    Thanks a lot for any responses

    Why don't you just use the answers you have seen ?

    Maybe there is no concise answer. Look in the guides

    I have some animations of mine in PAL
    If you created them then surly the creation s/w has a FPS option you can choose?

    otherwise guides, convert ...... all there and the methods do work

    Because they all seem to say different things so I thought I'd try and see if anyone had been through it themselves. Isn't asking and answering questions what a forum is all about?

    Rerendering from the animation package would take months of computer time, so that's not an option. I'll have another look at the guides if no one in here has been through it and is willing to help out, but they brought up more questions than answers last time i looked.

    This is what I do for my home DV movies (don't know if it would work for you):

    For the video only:
    - open the PAL .avi in Premiere Pro,
    - change the project settings so that it gives me the number of frame,
    - change the number of frames by a factor of 29.97/25,
    - render the video in a new .avi file
    - convert with TMPGEnc: output settings to NTSC and check the do-not convert framerate box.


    - author the converted video with the original audio file (re-sampled to 48kHz with either Audition or SSRC).

    Worked fine. No audio synch issue. Some slight deterioration of the video quality but better than any other solution I tested.

    OK here's the basic idea

    You have to rezize the video to 720 by 480

    You have to change the framerate to 23.976 without changing number of frames. this amounts to just changing header info.

    If there's audio you have to resample it in a ratio of 25/23.976
    to make it match the video which is now going 4% slower.

    You have to Telecine the MPEG2 stream to make it play at 29.97. This
    just amounts to inserting some bits in the stream. (3:2 pulldown)

    What form is the PAL animation in now?

    DV AVI format?

    MPEG-2 DVD format?

    Also what format is the audio in as well.

    Need to know this first to give proper advice.

    Also do you know if the video is INTERLACED or PROGRESSIVE?

    Important to know that as well.

    Heh, I know I'm gonna get totally bombed for saying this, but here goes:

    For an experiment, I used my Ulead Video Studio 6 and captured a PAL VHS using the NTSC DVD template, burnt it to disk, played it on my TV set & it looked FINE!?

  9. I have the animations in all forms really, so whatever's best to convert with is fine. I have uncompressed TGA sequences, Uncompressed AVI's, DV's, MGS2's and DivX's all either instantly to hand or very quickly creatable.

    Same with Audio. I have it as separate wav files when needed and embedded into video files too most of the time.


    Following the more basic advice from Matteo693, I've just put one of my files into TMPGEnc, loaded the NTSC DVD setting and saved the file out and it seems to look fine to me. Is there any way of checking that it is a normal NTSC DVD file that would work over on an NTSC system?

    That works for converting from PAL to NTSC but only if certain criteria are in place.

    1.) The PAL source must be PROGRESSIVE
    2.) You must check mark the option in TMPGEnc that says, "DO NOT FRAME RATE CONVERSION" and set up your encode as if it were a progressive NTSC source i.e., use 23.976fps and enable 3:2 pulldown.

    Now if 1.) above is true and if you use the NTSC DVD template in TMPGEnc along with doing step 2.) above then it will work correctly.

    Just be aware that this does adjust the running time from 25fps to 23.976fps ... in essense slowing down the video for NTSC

    As a result you also need to adjust the audio. This can be done with BeSweet and the BeSweet GUI just be sure to use the MOST current up-to-date BETA versions of both. It is best to do the FPS conversion from PCM WAV to PCM WAV and then if you want MP2 or better yet AC-3 audio you can do that AFTER the FPS conversion by THEN converting the corrected PCM WAV file to your desired sound format.
