I created some AVI files ages back following directions in this forum. Finally got around to dealing with them. I want to deinterlace them, do color correction, and use Topaz Video Enhance AI to upscale and cleanup. Then re-encode at a smaller bitrate with HEVC. I'm having some issues with the DAR,SAR,PAR and not sure how to deal with this. Soooo doing most of the below either with Lagarith codec or ProRes to limit loss...
Below is the original mediainfo for the original AVI made with the VHS tape:
Original:
Width : 720 pixels
Height : 480 pixels
Pixel aspect ratio : 0.889
Display aspect ratio : 1.333
Display aspect ratio : 4:3
If I use AVISynth and deinterlace in VDub with AVISynth and QTGMC the resulting file is:
Width : 720 pixels
Height : 480 pixels
Pixel aspect ratio : 1.000
Display aspect ratio : 1.500
Display aspect ratio : 3:2
OK so this just made it square pixels, and the display aspect ratio isn't the same either now. Is this a problem or not yet?
Color corrected in Premiere Pro and exported at DV 0.91 (includes extra data in for this output metadata):
Width : 720 pixels
Clean aperture width : 704 pixels
Height : 480 pixels
Clean aperture height : 480 pixels
Sampled_Width : 720
Sampled_Height : 480
Pixel aspect ratio : 0.909
Clean aperture pixel aspect ratio: 0.909
Display aspect ratio : 1.364
Display aspect ratio : 4:3
Clean aperture display aspect ratio: 1.333
Clean aperture display aspect ratio: 4:3
So kind of back to the original settings if this isn't killing the footage? Ran thru Topaz Video Enhance AI and doubled the size. Always wants to change to square pixels:
Width : 1440 pixels
Height : 960 pixels
Sampled_Width : 1440
Sampled_Height : 960
Pixel aspect ratio : 1.000
Display aspect ratio : 1.500
Display aspect ratio : 3:2
So square pixels again. Topaz does a great job in general. Now what? Do I open this video in Premiere Pro again as it's a big file right now as a ProRes file and encode in HEVC format and set the aspect to DV 0.9091? Is there a way and should I be trying to keep the video aspect ratio thru the stages?
