Some Noob queries regarding AviSynth

[GeoffWA]

Ok, fresh install AviSynth and QTGMC and now behaving as expected with the QTGMC result being best.

Thanks for the help people.

Below first pic is source (frame 10 from 25fps), others are frame 20 from processed output (50fps), last one is from fresh install "as expected" result from QTGMC

Looks good now. Glad you got it working.

One last question if I could get some guidance, what is a good lossless or almost lossless compression to apply to the files once deinterlaced, that is usable by the majority of consumer level editing packages like Premier Elements?

near lossless - cineform (comes with go pro cineform studio)
lossless - ut video codec, huffyuv, lagarith

Or, another workflow is to edit it first . It partially depends on the project and how much is being "cut" . If you're cutting lots out, it usually doesn't make sense to use QTGMC first - it's a waste of processing time if it's going to be cut out anyways

Also, any reason for selecteven() ? you're throwing away 1/2 the motion samples

I realised that so later I removed it from script and have 50 fps derived from original PAL DV.

I tried the Huffy and Lag lossless files with Premier Elements 12 but vid doesn't come through, it works on uncompressed file but I was trying make things a little more manageable if possible. I would say +80% of my footage will be kept, just broken up in discrete clips with a text tile at front describing date, event, where, who in shot and who was behind camera, then outputted in h264 at high bitrate.

I plan on archiving the original DV as is and the deinterlaced file in some compressed form. The deinterlaced file will be source for production of h264 clips distributed to relevant people.

I'll see if I can find the ut video codec to plug in to VDub and trial that.

Just click on the pink (Red? Orange?) link.

If you're using Premier Elements just to make text screens to add to the videos, that can be done easily enough using AviSynth. But maybe you're doing other things too.

Orange.

[manono]

Orange.

Hehe, yes, of course. Thanks for the definitive answer.

[aedipuss]

orange???

It's all an illusion , there is even more colors in it , but you perhaps mean that color was not an issue and true answer in all of this thread ...

Mainly slicing and dicing, sometimes a bit of tweaking on audio amplitude, the odd dissolve transition.

I tried conversion from uncompressed to UtV RGB VCM and Premier Elements will open it.

Another thing I still need to resolve, after processing with QTGMC the par/dar change from source 16:15/4:3 to 1:1/5:4, should I be trying to deal with this in the same script as a final stage with the QTGMC process?

[jagabo]

AviSynth is unaware of DAR or PAR, it sees frames as just 2d arrays of pixels. Just set those properties in your editor. In many editors you can right click on the video in the timeline or asset list and select Properties, or Aspect Ratio.

[GeoffWA]

OK, thanks for explaining that. I'll sort in in final encode to h264.

[poisondeathray]

Not sure about Elements, but in Premiere Pro it's right click the clip in the project bin => modify => interpret footage => pixel aspect ratio

If you're adding titling , graphics, overlays etc... you're going to want proper AR, or they will be distorted

Another way to do it is use square pixel equivalents for everything e.g. resize in the script after QTGMC before importing and set your sequence settings accordingly
