Can I just convert PAL to NTSC using ONLY TMPGEnc?

[aguinsburg]

Hi,

I had already read several guides about conversion from PAL to NTSC. But I only need to convert and MPG2 PAL file or PICVideo encoded PAL file to MPG2 NTSC file. As far as I try, TMPGEnc do it OK and I can see the video in my player, wich works in NTSC. Am I missing something?

Thanks

If your audio is in sync and you are happy with the results, then no, you probably aren't missing anything.

Well, I just tested a short video (3 minutes) and no problem. Is it possible to sufer audio/video sync problems with longer files when converting? Is there any tool to make all the steps in just one step?
Thank you

As long as you don't tick the box "Do not frame rate conversion" you should be fine. NeroVision Express will also transcode from PAL to NTSC but the results are not as good as with TMPGEnc.

What is not clear to me is why one needs to follow such complicated guides that includes several software pieces (BeSweet, Goldwave, TMPGEnc, and so on) and several steps, when one can do the job using JUST TMPGEnc. I am suspecting that I am missing something...

Some people claim that TMPGEnc is not very good for processing audio and use it only for the video side of things. Personally I have not had any problems although TMPGEnc does not of course support AC-3 which you need to make a 'legal' DVD.

TMPGEnc simply duplicates or drops frames as necessary to change frame rates. Specifically, when going from 25 to 30 fps it duplicates every 5th frame (thereby turning 25 into 30 for every second pf video). This leads to 5 small jerks every second -- usually only noticeable on smooth camera pans or when an object moves smoothly across the screen.

Also, TMPGEnc's resizing filter is not the best. It uses a bilinear algorithm. This can lead to a fuzzier picture and more moire artifacts than the Lanczos resizing that you can use in AVISynth or VirtualDub.

Yeah, and as result you have to encode about 20% more frames, that can lead to quality drop for the same bitrate.
