Append different field order videos

[cd090580]

Hi,

I've some holidays videos that where shooted with 2 video cameras.

One was recording to DVD, the other was on mini DV tapes.

Now, I'd like to assemble all these videos in one big file to made a dvd. I'll use Mpeg Video Wizard to cut the mpeg files and add the dv footage between 2 scenes.

But I have a question with field order.

The video from the dvd camera is Top Field First (given by DGIdex). I've read that DV to bottom field first.

So, can I encode the dv to mpeg (with any encoder) to top field first without any problems ?????

Thanks.

No ideas ??

Do I need to deinterlace, or reencode with the other field order ???

I'm only guessing no one is sure? I don't see any reason to de-interlace if your final output is MPEG-DVD. But I'm not sure about the field order changes. DV is BFF.

If no one gets back to you, try encoding a short test clip from the DV with the field order changed and append it to a short DVD video and see what happens. Some encoders may change it automatically, don't know.

EDIT: BTW, you might edit your subject title to something like 'Append different field order videos together' and you may get more replies directly to that question.

Field order is easily reversed by shifting the frame up or down by one scanline. So you can easily convert BFF DV footage to TFF if your encoder supports it. If your encoder doesn't support it you can use AVISynth:

AVISource("DV.AVI")
ConvertToYUY2() #if necessary
Crop(0, 1, -0, -0) #remove top scanline
AddBorders(0, 0, 0, 1) #add one black scanline to the bottom.

Open that in your encoder, make sure it knows the source field order is TFF, then encode as TFF.

Of course, a DVD can have a mix of TFF and BFF material so it's not really necessary to convert the DV to TFF.

HCEnc can do that job without avisynth ????

For DVD, so I can add directly all my files in the same VTS??

IE: In Tmpg DVD Author 1.6 (not 2.0 which don't work), can I directly add my files like this to one tracks.

Track1 => File1.mpg (TFF) + File2.mpg(BFF from DV) + File3.mpg (TFF)... ????

If not I will use you avisynth script and encode the DV to Mpeg-2 dvd.
