Matrox AVI and PPro

[Steven L. gotz]

The codec is different. Therefore it requires rendering. Not a lot different. Just different.

[Pavel Dibrov] “And why PPro with matrox needs to render Microsoft DV AVI if both are DV? “

Sorry, bur Matrox AVI and Microsoft DV-NTSC and DV-PAL are 100% compatible and therefore the latter do not require rendering in PPro/XTools.

In PPro/XTools, I routinely use Microsoft-DV rendered clips,in After Effects, “Type2 DV-avi files (Premiere; Vegas etc.)” captured in SCLive (Scenalyzer) or DV-NTSC clips captured in a secod computer, using Premiere Pro without the Matrox card.

hi! matrox codecs are upper field first. standart dv is lower field first.

Thanks a lot for quick responses 🙂 My camera is SONY DSR 250. What codec it uses? And what field it records first? What is standard then?

Thanks :)))

All [Pavel Dibrov] “My camera is SONY DSR 250. What codec it uses? And what field it records first? What is standard then? “

All MiniDV and Super8 cameras have hardware compression, as often said, “between the lens and the tape”. I have never seen the name of the compression algorithm burned into the hardware. One thing sure is that the characteristics of the clips captured from all DV makes and devices are the same, except for the important distinction between NTSC and PAL TV systems.

Video capture from tape with different cards copies , the digital signal to harddisk, without modifications in the case of DV AVI capture. Such capture also adds a header to the clip where, among others, a link is established between the clip and a compression decompresion codec to be used when required in editing, should it be using the Microsoft, Matrox, Canopus DV codecs etc.

With respect to the field dominance, Matrox uses Lower Field First for NTSC and Upper Field First for PAL. I also know that other NLEs always use Lower Field First, irrespective of NTSC or PAL.

I understand that there is some confusion in the interpretation of the DV Standard itself regarding this issue. That may create some problems with PAL editors that may, in cases, be forced to invert the field dominance when they use the same clips in utilities or editing systems that have different field dominance conventions.

Andre Gagnon, thanks a lot. It became clearer :)))
