2009年11月18日 · No. Standard definition 480i is 4:3. 720:480 = 3:2. The pixels are 10 percent taller than they are wide (PAR = 10:11). Note that a 720x480 video actually contains the 4:3 image in a 704x480 portion of the frame. There are 8 pixels added to each side for padding. So the full 720 pixel wide frame is slightly wider than 4:3. Using just the 704x480 ...

2020年8月3日 · But it DOES lose quality in the conversion, not even counting lossy compression. Mp4 will accept 640 or 704 or 720 (x 480) so no surprise. But like I said, you were Already at a disadvantage prior to ever even getting into your editor. Yes, you were able to export to 640 x 480, and the dvd software was able to "accept" that as a source.

2018年4月2日 · Dose It make any Different to Shoot at 4k In the Beginning, or Just shoot in 1080. Also, I did some test by Exporting To: You tube 720P, and also, Mobile Device 480 SD Wide, and uploaded to Dropbox. Honestly, when I watched the video with my I phone, I could not see any different. The only different was that Mobile Device 480 …

2013年3月3日 · The original dvd that is 720 x 480 vertically fills up less than my nero digital file that's at 720 x 368. How come the 720 x 368 file is vertically covering more area?

2011年12月12日 · Hi, This is one of those topics that I've not seen answered definitively. NTSC DV is 720x480 square pixels. If it's NTSC SD, the final display is 640x480 -- a 4:3 "frame" or screen aspect ratio. The pixels are squished (taller than wide) such that the pixel aspect ratio is .9091. But if you multi...

2018年9月11日 · The ideal is to only buy cameras that offer 10 bit 4:2:2 (or better) at all resolutions. The Panasonic GH5s and Blackmagic Pocket Cinema Camera 4K are good examples.

2024年3月1日 · I tried resizing my videos to 720 x 480 with a 4:3 aspect ratio by setting SAR to 10 width and 11 height, but it makes the frame 640 x 480 with added black bars. Is this supposed to happen? Or what should I do to resize to 720 x 480 with a 4:3 aspect ratio? The original sources that I have aren't 720 x 480.

2020年8月21日 · こんばんは、green_curryさん 「408」は「480」の誤りではないかと思われます。 「720 480/16:9」なら「DVワイドスクリーン」を意味しています。 ・720×480はDVのフレームサイズです。 ・ワイドスクリーンの場合はピクセル縦横比が1.2121ですので、左右方向はピクセル縦横比が1.0換算で872.71に相当します ...

2012年5月20日 · AFAIK the player will resize 720*480 to 720*544 to get the 4:3 ratio. For 16:9 you start with 720*360 stored as 720*480 and the non-square pixels (16:15) corrects that to a 1:1.78 ratio.
