HDV and full HD

[akkers]

I am just dealing with a HDV file and am curious about the difference between HDV and full HD.

HDV is 1440x1080 whereas full HD is 1920x1080. However, I can take a HDV file and use it a full HD project - the output looks fine with no distortion.

Can anyone please explain the relationship between HDV and HD. Thanks in advance.

Can you post Mediainfo results for both videos?

HDV uses a Pixel Aspect Ratio of 4/3:1.
So the frame that Full HD would store in a width of 1920 is horizontally squeezed down to 1440 pixels in HDV.

To put it in a Full HD project the width would have to be resized from 1440 to 1920 (making the Pixel Aspect Ratio 1:1).


HDV is not Full HD, but that doesn't mean much.

HDV is full HD. it is captured on the camera's sensor as 1920x1080. it is compressed to allow it to be written to normal miniDV tape at 25MB/S. all decent editing software automatically re-adjusts HDV input to 1920x1080 on the timeline. the only thing you have to make sure of is that it was shot at the normal 30i as both 24p and 30p are possible options and there is a small chance if it came out of a jvc cam it could be 720p60.

HDV is full HD.

HDV is 1440x1080 (anamorphic). How is that Full HD?

"Full HD" doesn't really have a specific definition. It's used in advertising to mean 1920x1080.

Sony Professional broadcast XDCam also has 1440x1080 modes and nobody argues that isn't "full."

Don't get bogged down in semantics. Is 1280x720 "Full" HD? A lot of broadcasters think so.

when NLE upscales HDV while rendering into 1920x1080, it just upscales horizontal resolution a bit, not vertical, so result looks always good basically

HDV is still a gem because you can edit and output losslessly (except reconstructing of a GOPS if cut within), rendering without change in any NLE basically, unfortunately HDV camcorders are old (consumer camcorders), and stabilization is not up to date also, and capturing into PC is a pain

I have a Canon HV40 which records to tape in HDV 1440x1080 4:3 PAR which is equivalent to 1920x1080 1:1 PAR, i.e. 1440 times 4/3 is exactly 1920. However obsessing over the difference is usually pointless because the thing that really matters is how many lines can your camera really resolve. If your camera can only resolve 700 or 800 lines then encoding that as either 1440 or 1920 doesn't matter, sadly. I believe the only way to truly get 1920 lines of resolution is to get a 2K or 4K camera and downsample to 1920.

No, there are better "HD" cams that actually resolve to full 1920x1080. Just not the cheapo ones.

********************

"HD" is a general term which can describe 960x720 (@4:3 PAR = 16:9 DAR), 1280x720 (@1:1 PAR = 16:9 DAR), 1440x1080 (@4:3 PAR = 16:9 DAR), 1920x1080 (@1:1 PAR = 16:9 DAR), or a few other rarer ones. Basically anything ABOVE ED (720x576 progressive), but below UHD.

Sure for the right price
