How do you set video resolution in HCenc?

[Maikeru-sama]

I have used HC for a while and I always thought that when you chose "mpeg", it was going to make a 720x480 NTSC Compliant DVD.

I am trying to encode an MP4 file to DVD but HCenc is setting the resolution to 752x496 and of course one of my DVD Authoring tools is complaining about the resolution. I tried to find an option that allows you to specify 720x480 but didn't find one in HCBatchGui or HCGui. If all else fails, I guess I can just use CCE but I would like to know the answer.

Avisynth

DirectShowSource("c:\mymovie.mp4", audio=false)
LanczosResize(688,464,0,4,1024,568)
AddBorders(32,16,32,16)

HC ini file

*MATRIX     mpeg
*BITRATE   2500
*MAXBITRATE   8000
*PROFILE     best
*DC_PREC     10
*SMP
*PULLDOWN
*ASPECT     16:9

HC doesn't set resolution, it uses whatever the source provides. If you want 720x480, make sure your Crop, Resize, and AddBorders commands provide it. Mpeg is not exclusively for DVD so other resolutions are allowed.

You set the resolution in your AviSynth script, NOT in HCenc itself. 688 + 32 + 32 = 752 and 464 + 16 + 16 = 496, so that's where you are getting this resolution from - YOU told the program to use it in your script!

There's a big difference in aspect ratios between 1024x568 and 688x464.
Why are you trying to use 688x488 anyway? Maybe you have a good reason. That's why I'm asking. Something like this should be OK:
LanczosResize(640,362)
AddBorders(40,59,40,59)
This will give you 720x480 output, valid for NTSC DVD.

I'm not an AviSynth expert, so if your 688x464 has a good reason for being used, I'd welcome the education and opportunity to improve my knowledge on the subject.

Your average bit rate is really low. That's SVCD level. Setting the max to 8000 will help some, but still that's a pretty low bit rate.

Oops!!

Disregard, it was a copy/paste error. Should have been "AddBorders(16,8,16,8)". There are 52 mp4 files and I find/replace on the LanczosResize but forgot about the AddBorders Function.

The subtitles for the MP4s that I am working with have burnt-in/hardsubs and the Avisynth script is directly from FitCD with 1 block for overscan.
