Is the below still the preferred method to crop (mask) the overscan from VHS capture?

How to Properly Crop the Overscan in VirtualDub [GUIDE]

I captured at 720X576 and see the junk mainly at the bottom of the video. Need to look carefully at all other edges to see if there is any noise.

Are there any better methods since the above guide was written a while ago?

Also, apart from being able to hide the overscan with black bars when viewing on a computer screen, are there any 'bitrate' related advantages for masking the overscan (before going to DVD)?

Also, in the below thread admin wrote that resize is best done after de-interlacing. The above guide includes a step for resizing. Do we need to deinterlace then? (goal is DVD).

How to best perform overscan correction?

First, deinterlace the video with a good method. You cannot resize an interlaced video very well
Some of my questions may not make sense for pro's like admin, kpmedia, but please bear with me, I am not a pro.

Thanks.

- VirtualDub crop/mask = Yes.
- Yes, bitrate use is optimized. It's no longer wasted on noise, but instead used for the actual picture.
- If goal is DVD, don't deinterlace. (Streaming conversions only.)

1, 2, 3 ... easy enough.

Thanks LS. Happy to see your reply. I am hoping you are back in full action.

I saw a filter 'Fill with borders' or something like that in DFAQ version of VDub. Used it and the result is pretty good. It effectively puts black borders as per our specifications.

Is that same as using VirtualDub crop/mask method?

regards
