What video width should I choose for best medium HD quality?
I've noticed that there seems to be 2 popular ways to make a blu-ray encodes. One where the width is 1280 (720p) and the other where the width is 720.
This seems to depend on the aspect ratio of the video but is not always the case. Presuming I'm on the correct track (I'm a noob).... I would appreciate some input in which to pick and the reasoning or rules to use. Like if you have a 2.35:1 use such and such and if you have 1.85:1 use the other one. If I have it all wrong about it having to do with aspect ratios, then please enlighten me. Thanks! EDIT: I figured things out. Thanks. See post #4 Last edited by kinster; 17th November 2014 at 16:18.

OK thanks. I'm not really concerned with hardware players. Lets forget about 720p for now. After your post, I investigated things a bit more on my end and realized I was asking the wrong question. I've since edited my question to better reflect what I'm after.

Alrighty. I think I figured out my confusion...
I've only done a couple of comparisons and the 1280 width (720p) ones are better quality so my question is answered. The 720 pixel width ones I was talking about are called something else. I'm not sure if I'm allowed to mention the words that something else is, so I wont. These types are of lower quality. I thought I was dealing with the same types which led to my confusion. Hopefully this thread might help someone in the future asking the same type of question. Last edited by kinster; 17th November 2014 at 16:18. Reason: punctuation and other cleanup |

720 pixel width is just SD video ('old school' DVD resolution ). 720x480, using the 'p' designation, it's 480p.
SD = 480p (assuming progressive), 720x480 if using the full screen (aka, DVD) 'Full HD' = 1080p, 1920x1080 if using the full screen (aka, Blu-ray) (1920x[something smaller] if letterboxing is cropped off) 720p is an in-between resolution of HD (1280x720 if using the full screen, same as above). Frequently used for HD broadcast, but even those are now getting bumped up to 1080.... So a 1920x800, while technically isn't 1080 pixels high, is still considered '1080p' by most people, likewise for 720p and 480p. Though anything in the 720x480 range is usually just called SD. There's nothing shady about the 720 width video, unless you are associating it with a common term used for piracy (like 'cam' or something), but that has nothing to do with the official designation of 720x480 video. |
