how to upscale the video resolution

[enzino]

Hello,

I have a video in 352x288. Through AVStoDVD I have changed it in PAL from the original video 352x288.
I have made an attempt in order to upscale the resolution: through Avidemux I resized it to 704x576; then I have used AVStoDVD.
I am not completely sure, but it seems to me that the best resolution I can see on TV about that video is the original change in PAL from 352x288, instead of the DVD coming from 704x576. This difference if exists is really slight.
The resolution on TV is not good either for the DVD coming from 352x288 and for the one coming from 704x576. How could upscale the resolution at the best size I could for tV, by using AVStoDVD? What steps (what menu and buttons to press) in order to upscale?

Thanks,

Enzo

Try doing it in the reverse order
resize in avidemux before creating the dvd folder with avstodvd

Or skip avi demux completely
Avstodvd
Can resize to DVD STD and change from PAl to NTSC or vise versa 'if needed' you do not need to use avi demux
When using avstodvd.. Edit the settings, unchecked auto avi snyth script, click enhance, choose deblock
Enter 20, for the value
Use hence encoder 1/single pass use constant quality
I think you will be happier with the results

Will Avstodvd let you use nnedi3 to upscale? That's usually the best upscaler.

it doesn't come with it, although i think ti can be added to avisynth and manually added to avisynth script in avstodvd
i always use lacrosse resize

Hello,
I have tried editing the settings, but after pressing either the button Settings or Preferences, I can't see none of the following options: auto avisynth script, enhance, deblock. How could I see them?

About nnedi3 I clicked: Avisynth - Download new plugins - nnedi - I can see only a dll file, but I don't know how to "join" it to Avisynth and to AVStoDVD. How can I setup nnedi3? I have downloaded the zip file, but in particular I don't know where to use the code into this link AVStoDVD

About lacrosse, I haven't yet found it.

The easiest way to install and use third party AviSynth filters is to put the dll in AviSynth's plugins folder. Then in your script use:

nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=704, fheight=576)

Regarding lacrosse resize: I think he meant LanczosResize(). nnedi3_rpow2() will deliver better results with less aliasing and less oversharpening halos.

I put the .dll file into the plugin folder; then I have created a txt where I have copied and pated the code; then I have changed the txt extension in avs extension. I put this file into the folder Scripts example.
Is correct this destination folder? How can I run the script?

Not correct destination folder. I keep my AVS scripts in the folder of the video on which I'm working. You run the script by first opening it in Virtual Dub (File->Open Video File) to test it to make sure it's a working script. If it isn't, give us the complete script and the complete error message. If it is, you can then use that same script in any encoder that accepts AviSynth scripts as input.

Once it's passed the test and you want to use that script in AvsToDVD, replace the script it's using with your edited one.

Hello,

the script returns the following error:

If it isn't, give us the complete script and the complete error message.

You only provided half of what was requested. Did you copy what jagabo wrote?

[enzino]

Sorry! Yes, I copied that.
The script is:

nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=704, fheight=576)

[jagabo]

Post your entire script. Do you have a source filter? Something like:

ffVideoSource("filename.ext")
nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=704, fheight=576)

Note that ffVideoSource() doen't come with AviSynth. You have to download and install it, just like you did nnedi3. If your source is an AVI file you can use AviSource() instead. Or you can try using DirectShowSource(). Both of those come with AviSynth.

Hello,
it worked ok with Virtualdub. Thanks.
How can run it with AVStoDVD?

Maybe someone can give you a more definitive answer since I don't actually use AvsToDVD. But wherever it shows you the AVS it's going to use for the encoding, you should be able to edit it to replace what it shows with your script.

What I did is:
File - Open project - selected the avs script (this file was with the file video, that is in the same folder) and then started the conversion. Now the video seems having a good resolution.
Thanks to everybody.
