movie is flickering after capture

[nojee]

hi

when i record something /camera: Sony dcr vx2100e/ and capture with my matrox RTX100 the pictures got flickered, especiallly when there is fast movement in the film. the movements are not smooth.

what do i do wrong, is that camara settings problem or the card?
i am using windows XP, SP2
please see attached screendump of the video with the problem.

What your seeing is interlaced, You need to deinterlace.

Not familar with the matrox cards but you have a DV camera and should be capturing toO DV-AVI. It's not really a capture but a transfer, simailr to copying a file. What you use to to do this makes no differenc in the file as long as it's over firewire with a DV-AVI setting.

The flickering you see could be caused by the interlacing which is the lines you see in the image you posted. This is normal and if you're fianl output is for TV you want to leave it interlaced.

Suggest you try burning a test clip to try on TV to see if it's still present, you cannot use a monitor to judge the final quality. The video played from a DVD should be nearly indistiguishable from the same video played directly from the cam.

i use firewire to copy the DV AVI to my computer, then i edit it in Premiere and convert it to MPG2, to have a DVD output /then from Premiere it goes to Encore/ and burn the DVD

now what i see on the DVD /both on the comp and on TV/ is the same as the screenshot above, interlaced.
How can i deinterlace it, at which step did i loose the quality?

i was thinking its even before the capturing, something to to with my cameras exposing time /opening time of the lenses?!

It could be a wrong field setting. DV is bottom field first for PAL or NTSC. This should be the setting for the Premiere project setting and the MPeg2 encoding. If this is set wrong, you will see flicker that gets worse the more motion is in the scene.

Deinterlacing will lower quality from a DV format source. The interlace lines will not be visible during normal TV playback. For computer playback, use a deinterlacing player like VLC or Power DVD.

As EdDV mentioned you could have switched the field orders. Also as he mentioned deinterlacing will lower the quality not improve it. When you deinterlace you are essentially throwing away half the resolution of the video because generally one field is removed and recreated through interpolation from what remains. Unless you want to view this video strictly on a computer leave it interlaced, even then I would only suggest deinterlacing if you want to distribute the video over the net.

If this flickering is present when you play the video directly from the cam then you would be correct. In that case this is a completely different issue than a capture/encoding problem. What you can expect though if done properly is for the final DVD to look nearly identical to however it looks when you play the video directly from the cam to a TV.

i was just checking the original DV avi, imported from the camera via firewire:
no flickering there.
so it should be on the way to encoding to MPG, probably the wrong field setting /top instead of bottom first/. thanks for the help.

is there a simplier way to create a movie in premiere for dvd without all this struggle?
so I get the AVI from the camcorder, /how can i maintain this superb quality?/
whats the best file format to use to work with Premiere and Encore - withouth loosing quality and producing for TV (PAL)?

The rules for making good are pretty simple and apply no matter what application you using. The less you do to it the better off you are. Leave it as DV-AVI and make your edits and convert it to MPEG once and and only once. Not familiar with Premeire but if it doesn't support MPEG output or you want to use another encoder that Premeire doesn't support export as DV-AVI.

You seem to be on the right track, try flipping the field order and export as a high bitrate MPEG and compare it on a TV to how it looks if played directly from the cam. If it looks identical or nearly identical you have succeeded.

One note for Premiere. The default encoder settings (7Mb/s or 6 Mb/s average VBR) are overly compressed for quality DV material IMO.

Try ~9400 Mb/s CBR (with compressed audio) or ~8200 Mb/s (with PCM audio) for a higher quality MPeg2 encode.

Primiere will do mpeg if you buy the codec for it

i used primiere for the DV-AVI cams i used at school and we usually saved our movies as .wmv since primiere saved it as .avi itself

This is a problem with the Matrox system when using PAL. They follow the 'blue book' and the frame order for PAL is upper first not lower first as per NTSC and every other program. Still a very good card to work with.
Go over to their forum http://forum.matrox.com/rtx100/index.php?sid=d9ab774ca66fb2ebc268a27d6382ca5d
and check out all the complaints from PAL users. It does depend on what you are trying to do and which programs you are using. If you stay within the Premiere Matrox environment it is ok but remember the frame order if using 3rd party such as TMPEG
