Encoding: DV Passthrough Deinterlace to original framerate?
If I use my DV camera as a passthrough device to capture old VHS tapes, the "captured" file on my PC is now 29.97 interlaced.
Would I be correct to say I can run the "30i to 24p" script safely on this video, REGARDLESS of the ORIGINAL format? ie: doesn't matter if the original was 23.976, telecined, PAL, whatever... Is this true, or do I still need to consider the original source? Thanks, Icarus |

As for PAL input with an NTSC camera, I've never tried so I don't know what the results will be. If the camera even accepts it, I expect the fields of the video to be really messed up... |
It was my understanding that using a DV camera for capture isn't quite the same as an analog capture card, because the DV camera converts the output to 29.97 interlaced. I thought the DV camera converts the video to 29.97 interlaced so that all output from the DV camera is "real 29.97 interlaced" regardless of the original source.
You are suggesting that I'm wrong (which has been known to happen from time to time :lol: ). Can you explain what is wrong with my understanding above? Thanks! Icarus |

It's similar to using DVD2AVI -- all NTSC DVDs are 29.97fps (just like all NTSC video tapes), so DVD2AVI has to decide whether its telecined, interlaced, or progressive video and sometimes gets it wrong... I don't know how it would work for PAL. If the camera is able to read the signal at all it will probably look something like the output of the ConvertFPS() function in AviSynth -- part of the previous frame will be captured along with the current frame since the framerates don't match. But if you try it I wouldn't mind hearing what it actually looks like :-) |
