(There are " super resolution" scaling techniques but I don't think any upscaling DVD player does this.)Ĭheck out this overview on interlace. About the best you can hope for is for it not to introduce too many scaling artifacts. Oh, and upscaling standard definition DVD doesn't make it high definition. You have to try both options with different sources and you have to know what defects to look for. This is one reason why much sports (ESPN for example) is broadcast at 720p.Īll the processing going on makes it impossible to predict what will look better on an HDTV.

Smart deinterlacers will maintain the full resolution in non-moving areas but will fall back to half (vertically) resolution in moving areas.

A good 1080i film source will look sharper on a 1080p HDTV than on a 720p HDTV (assuming you are sitting close enough to the TV to see the difference).įully interlaced 1080i (live video sources like sports and the news) have to be deinterlaced in some fashion. That same content in 720p would offer a soft upscale to 1080p.There's no simple answer as to which is better.Īny decent HDTV will inverse telecine any 1080i film source back to 1920x1080 progressive frames, then display it at the TV's native resolution. Now that 1080p (or higher) TVs are normal and film content detection is a fairly standard feature, any 1080i signal derived from film content should be able to be de-interlaced to a proper 1080p picture. Anecdotally, I can say that NBC and CBS football broadcasts (1080i) look way better on a 1080p/4k TV than FOX or ESPN (720p), and sports is the scenario that was always touted as the advantage for 720p. I'm sure someone with more technical knowledge can give a better technical answer, but from what I know, de-interlacing techniques have improved significantly since the mid-2000s. These days, with 1080p TVs being the minimum standard, the question is whether an upscaled 720p is better than a de-interlaced 1080i signal.

And, once you convert the 720 to 1080i, then you're simply subject to 1080i's disadvantages, but with less source pixels. Any advantage of the video format as it pertains to motion was more than offset by the LCD blur imposed by the technology of the time. However, there are mitigating factors here, both then and now.Īt the time, the argument about motion could almost be completely nullified by the fact that LCD response time in the early to mid-2000s was terrible by today's standards. Particularly, in vertical motion, you would have a significant decrease in perceived resolution. While at any given moment, you would have 1920x1080 unique pixels in a 1080i signal, because of interlacing, you would experience artifacting in motion. This is where the 720p crowd really dug in. While the latter is far superior, I feel like either way, you're worse off going from 1080i -> 720p than the other way around. A higher quality TV would de-interlace the 1080i signal, then downscale to 720p. If I remember correctly, the cheapest of cheap TVs would simply take each 540 field and upscale it to 720p. 720p to 1080i usually worked fairly well, even before modern post-processing. Still, most decent TVs took both signals. So, one could argue that the only true "universal" HD format is 1080i. Now, a few of the earliest 1080i TVs didn't support 720p signals at all.

But, given that all things are not equal, we had to deal with non-native formats. If you are doing pure math, 720p/60 will give you more pixels per second than 1080i/60 will.ĭespite our self-centered viewpoints, the real answer was that the format native to your TV was the best. And of course, even cheap modern TVs are generally at least 1080p (you can still find a few super cheapo 720p TVs out there, but it's not common). Obviously now, these are both inferior to 1080p or UHD, but all broadcast channels are still based on these formats and, due to bandwidth, will be for the foreseeable future. If you had an HD CRT, as I did, you were team 1080i. Now, the team you played for was essentially based on what TV technology you owned (sounds familiar). However, people really did argue about this. I'm assuming everyone here is aware of how the two formats work, so I won't go into that. It just made me think about how far we've come from arguing about the original HD formats. I was reminded of this based on the gaming side thread about 4k vs 2160p or 2160c or whatever. In the early days of HD, people argued about.
