Will this AviSynth script file work for QuEnc?

[dell400sc]

Hey Gang,

I want to try encoding my Type II DV-AVI file that i capture from my DV camcorder via Firewire to my computer using QuEnc since I want to compare results from encoding with TMPGEnc Plus.

I record my video in 16:9 and capture the avi via Sony Vegas 5. When I use TMPGEnc I encode to NTSC 16:9.

Will the following AviSynth script suffice for inputing to QuEnc?

AviSource("J:\movies\clip1.avi")

or do I need to add other info to make it work the same as TMPGEnc? I don't add any editing/filters in TMPGEnc I just usually point it to the AVI file, encode DVD NTSC 16:9 29.97fps 2-pass VBR 5000/7000 and encode resulting in an m2v and wav and then I encode the wav to AC3 and then use TMPGEnc to make DVD.

I would also be interested in knowing about decent filters to apply to the script to improve video quality.

Thanks,
Lex

Just curious. Why don't you try it and find out for yourself if it will work?
Then you can ask for help if you encounter problems.

I agree with tdan that this is something you should try on your own, but QuEnc can probably be made to accept a pseudo AVI file (a .AVS script), just like Premiere, or any other video editor or encoder

Roger that guys...just doing a little research from work first to help speed up the process. In reality I think I want to ultmately find a good DV script for watching encoded avi-mpeg-2 on TV and use if most often.

Thanks again!

Doesn't the later versions of Quenc support direct loading of avi/wav files (by creating a temp avs file)? I think so... if your Quenc version won't take it directly the make sure that you get one of the latest versions.

So try to load the avi directly in Quenc.

Else check out the www.doom9.org forum.

Okay I finally used Quenc with Avisynth. My script looks like this:

AviSource("c:\folder\myclip.avi")
ConvertToYV12(interlaced=true)

Now after encoding wth Quenc for DVD high quality the result was good on still footage be everything that moved created horrible footage (macro blocks etc.). Should I add or change my avs script?

Thanks,

Try changing your field settings in Quenc to the opposite of what they were on the bad looking encode.

Read this thread as well (long, but informative)

Well, no I don't think you should add anything to the script. Then as I understood you use the same bitrates in QuEnc (5000/7000), high quality, VBR, two pass encoding. In advanced settings you check Interlaced encoding (uncheck TopFieldFirst) and 16:9 and Scene detection?

[dell400sc]

Abond,

No, I don't have Interlaced encoding checked nor to I have TopFieldFirst checked. I also only have 16:9 checked and not Scene detection. Which ones should I use?

Thanks,
Lex

Soopafresh...I'll start reading

[dell400sc]

Well checking Scene detection and Interlaced encoding cleaned up the output and now it's probably par with my TMPGenc encodes.

Now I just need to find a filter or two to apply to the avs script for DV 16:9 video source to make my videos looks a bit better.

Thanks,
Lex

Carefull with filters. You should be sure they support interlaced material, otherwise the output will be horrible. If you want to use a filter that doesn't support interlaced material, you must separate fields , apply the filter and weave the fields back.
