[Georgesfari] “whats the usual data rate for DV AVI captured from DVcam (16×9) ?? anyone??”
The data rate for SD 16:9 is the same as 4:3, 3.75MB/s, the pixel count is the same for both, 720×480 just the horiz size of the pixel is difference, .89 for 4:3 and 1.2 for 16:9 -
[Ron Shook] “There is a standards conversion problem with ProCoder Express currently. It doesn’t give you clean conversion”
Hi Ron:
Haven’t heard anything about that, I mostly use Procoder, but I’ve done a few conversion in PCex and haven’t had a problem, do you have a reference for it? -
Probably what happened is the cam operator filmed in the EVS mode vice the normal interlaced, some people confuse the EVS with Pro scan because it uses individual lines in the field vice the two line overlap thats used in the normal interlaced mode, in AE in the no fields mode you probably are combining the two EVS 50i fields to form what could be looked at as a 25p frame except that there is the time difference between the two EVS fields so you can get motion artifacts and aliasing.

[casting shadows] “igotta do it myself before i give it to him.”
The expensive Procoder was mentioned as conversion software, but Procoder Express ($60us) will also do PAL to NTSC conversion as Procoder but a bit slower, still uses the same software core though so its quality just as good .

[Georgesfari] “my camera man said he was absolutely sure he shot it in prog scan(can’t turn back time to check…) and so i believe him(as I’ve asked several times if it was prog scan or not) …”
I rent 570s from time to time both NTSC and PAL for film conversion and have never seen a progressive scan mode on either, there is a EVS mode which changes the vertical resolution but it still is interlaced.

[Paul W] “the file is 48 kHz. I was looking at the wrong file (working too fast). I played it on Windows Media Player and the audio and video are out of sync on that as well.”
Usually DV audio doesn’t go out of sync unless the audio is unlocked from the video or the recorded sample freq is off.Did you check in the VCR mode and see if you were 12bit or 16bit, the default on most Sony cams is 12bit.
You need to make a analog->DV dub in the VCR mode and then see if it captures OK.
If you don’t have this problem with tapes you recorded in the camera mode, but have it with tapes made in the VCR mode the sample freq maybe drifting while in the VCR mode -
Try dubbing to a DV tape and see if the same happens, also make sure the camcorder is set for 48khz and the same with the project.

[plainman007] “The files remain as mpeg2 which adobe after effects and premiere boast that they can edit. Correct me if im wrong please”
Where did you read that? Premiere has a codec available to encode finished DV to Mpeg, but not edit.
Various Premiere versions can edit mpeg files, “IF” is a proper plugin available(mainconcept.com), or if there is third party hardware and the software associated with it present on the machine, some people have a fix of using a freecodec pack and switching to another codec but it can make a god awful mess. -
It would help if you told what version of Premiere you have, and whether or not you want chapters, etc.

Its not necessary to stripe DV tapes before use, DV doesn’t use old time code except as a starting point for a new scene, if a cam is turned off when turning back on always check the time code display before starting a new scene if its zeroed out just back the tape up a hair till you see time code from a previous scene, if you strip a DV tape you could have broken time code on every scene because DV overwrites anything on the tape except for the last time code it references and the new tracks maynot align with the old stripped code so if you stripe you waste time and have extra wear & tear on the equip.
When plugging in the mic you might have glitched the recording process somehow, always set your cam up before the shot, minimize futzing with the cam while shooting.Also the the device control for a VX2100 is basically the same as a VX2k
