Resolution / video converters

Postby Mindblower » Sun Jan 20, 2013 6:35 pm

There is software out there than can change the dimensions (resolution) of a video (disc) movie (tv show). I sort of know how software can change the audio bit rate of a mp3 formated song, by compressing it, but does it work the same way with video.

If the source material was in full 1080 resolution, I can see that shrinking it would be easy. However, can the reverse also work? If the material was in a lower resolution, say 624 by 352, would altering it to 1280 by 720 show flaws on a larger screen? And how large would that screen need be?

Seems software can do so much with digital media, Mindblower!

I am a novice and relate to experience some years back when I dabbled with this sort of stuff. If the video is burnt at low resolution it was impossible to reburn it to a higher resolution and maintain good picture clarity. You would end up with a blocky picture.

The same applies with low resolution videos which can be crystal clear on a 624 x 352 windowed screen but as soon as you opened it up in full screen or changed to a higher resolution the quality would greatly diminsih. You see this alot with youtube video's.

There may have been improvements in software but I think the same problems are still there. Hopefully someone with more indepth knowledge will come in here and say otherwise.

Fancy meeting you here Spudz. ;)

I should of made myself clearer. By videos, I'm talking about digital media, not the video (VHS) units. I d/l torrent files (tv shows), and most are in the 624 by 352. However, some are listed as 720 or 1080, thus the file size is much larger. Am wondering if the 624 by 352 are pre-shrunk for faster u/l / d/l. I've played around altering the sizes, and cannot see any difference, even side by side, on two 24 inch monitors, which are 1080 listed, Mindblower!

LOL, :D :lol:

I would guess it for up/down quick data transmission while still maintaining watchable quality and compatibility for both desktops and the new hand held devices.

So far, the HD quality 624 by 352 torrents can be viewed on the older TVs via a player. Those of a higher resolution like the 720p cannot. But, using software, and converting to a lower resolution, they can be viewed on the older TVs. Playing on a good quality monitor has not visible difference that I can see, since I'd need to have two side by side to truly see. I've taken it up to a 48" screen, and the shows look fine, Mindblower!
