Hi All,
I'm capturing VHS via
VirtualDub as uncompressed UYVY.
I want to encode it with FFV1 as final result for storage.
Here’s the part I don’t fully understand.
Captured file, UYVY, doesn’t have any flags whether it’s interlaced or progressive.
In fact, according to this page, UYVY is always progressive:
https://www.loc.gov/preservation/dig...dd000365.shtml
FFV1 encodes it as progressive as well and now if I check media info, it’s progressive.
In any case, for both UYVY and FFV1 the content is kept as interlaced:
Code:
ffmpeg -filter:v idet -frames:v 100 -an -f rawvideo -y NUL -i D:\VD\VHS_full_FFV1_pass1.mkv
Code:
[Parsed_idet_0 @ 000001bbf074e480] Repeated Fields: Neither: 101 Top: 0 Bottom: 0
[Parsed_idet_0 @ 000001bbf074e480] Single frame detection: TFF: 101 BFF: 0 Progressive: 0 Undetermined: 0
[Parsed_idet_0 @ 000001bbf074e480] Multi frame detection: TFF: 101 BFF: 0 Progressive: 0 Undetermined: 0
My question is, do I lose any quality by encoding interlaced content as progressive?
Will there be any problem to deinterlace such encoded video in the future?
Thanks in advance!
