Hi,
I am trying to render concert footage I shot with the Panasonic Lumix LX100 in 4k 25P out to Blu-ray for DVDA but am having trouble retaining the excellent detail of the footage (25,000 fps progressive, 3840x2160x12, AVC).
I am using the Blu-ray 1920x1080-50i, 25 Mbps video stream template (variable bit rates 40-30-25 mbps), and the result is really blurry, and not just in panning shots but in screen shots with no or little motion. If I switch field order to progressive, DVDA will require recompression (to interlaced), as the only viable option in DVDA is MPEG-2 1920x1080-50i. (The two progressive scan options, 24.000p and 23.976p would require me to use those frame rates in rendering; I tried it and the results were even blurrier.) The AVC options make no difference here to my mind. (Correct me if I am wrong.)
What's more, the MPEG-2 interlaced render of the footage (40-30-25mbps) pales in comparison to the MP4 (AVC/AAC) Internet HD 1080p progressive render (24-20mbs) I made as far as detail is concerned, the latter being virtually as sharp as the original, at least in Best (Full) preview quality on the computer screen , at almost half the bit rate. This, to a layman such as myself, seems strange.
When I imported the MPEG-2 rendered m2v file into Vegas 13 and sharpened it and then rerendered it (this of course meant recompression), the result was better than the original render, though still not on par with the MP4 version.
One would think Blu-ray would be superior to YouTube versions, but in this case it falls short.
Is there anything I could do to retain the quality of the progressive footage?
Note:
What I could have done in the first place was shoot it in 4k 24P, and which would nicely render out to 24p using the MPEG-2 1920x1080-24p, 25 Mbps template, which DVDA has a video format setting for requiring no compression.
Two questions on 24p, though:
1) is there a marked difference between 24p and 25p to the naked eye?
2) should I choose the 23.976 option over 24p in DVDA (the frame rate in the MPEG-2 template is 23.976, which is the actual frame rate of the 24P 4k footage?)
I know this may have been addressed before, but couldn't really find answers so any help greatly appreciated. And I posted it here instead of DVDA as that forum seems much quieter than Vegas Pro and truth be told, this also deals with rendering in Vegas Pro.
Cheers
