learning scripting for dv?

[gavo]

What are handy filters for dv? Does anyone have a example of a good dv script?

Did you look around in the DV forum?

well, DV is basically just video footage. only things that might need special treatment are:

- blocking... yes, even at 25mbps it'll still go blocky sometimes. usually if the encoder (in the camera) makes the wrong decision between interlaced and progressive coding of a block. there can also be ringing if there's very sharp edges in the footage.

you can fix this with your favourite deblocker at very low settings.

- in NTSC DV (not PAL) the colour sampling is terrible, and gives you artefacts when there's strong colours around. this also makes it less useful for chroma keying.

this can be mitigated (you'll not get the data back) with the ReInterpolate411 filter.

aside from that stuff, treat it like you would any other kind of video. be aware that there'll probably be a lot of noise, simply because DV implies a 1 chip consumer camera in low light (but not necessarily of course - it's often used as a DVD mastering format, and is perfectly alright in that vein, at least for PAL).

for more particular stuff you can check out the DV forum here :)

[edit]

another handy filter for DV is one that reverses field dominance. DV is bottom-field first in a world of top-field first. this means field order is likely to get screwed up in pretty much every project that involves DV at all (and any projects worked on with the same editing app, because the settings weren't changed back). you have a few choices with field-order depending on whether you're working to output back to DV tape, or output to DVD or digibeta. for the former keep it bottom first, for the rest make it top-first. the easiest way to do this is shift it up or down by 1 line. don't ever trust premiere to do it for you, as it'll completely botch it. FCP does it alright, but requires a re-render. avisynth does it superbly and has many choices of how to do it, so if possible do it in avisynth (same goes for pretty much everything else but cuts actually).

And if you're shooting with a consumer DV camera you may also want to disable electronic image stabilization (if its optical / mechanical - leave it on) and apply a stabilizer in AviSynth (DeShaker in VD / Depan in AviSynth). Also you may want to take a look at the excellent HDRAGC (http://forum.doom9.org/showthread.php?t=93571) filter to increase brightness the 'better way' :)

For heavy pixel manipulation take a look at Reinterpolate420 (http://forum.doom9.org/showthread.php?t=82787) (only PAL!).
