Converted videos display issues

[thumpy]

I have some tv shows that the resolution is smaller and it fills up the screen. I have some that I converted to 720p and 1080p and it doesn't fill the screen. You get black bars on the side. Is that because the original person that uploaded the videos set it up that way? Is their a way to get those videos to fill the screen?

It gets complicated. Give us more info about source formats, resolution and PAR. Also your playback methods. Fill what screen?

[thumpy]

The screen I refer to is my HDTV.

One example of a file that fills my tv screen is a avi file with resolution of 657x548

this file does not fill the screen and has black bars on the sides. Mp4 1920x1080


If you need the mediainfo I can provide it if that would help?

The resolution only tells part of the story. For example, a 4:3 movie encoded at 1920 x 1080 will have black bars up the sides to preserve the original aspect ratio.

That said, if 657 x 548 is filling the screen, it is either being zoomed, or displaying distorted, as it is not a 16:9 resolution (and it is really badly encoded - odd number resolutions are usually not allowed).

DVD, DV, ATSC, DVB etc. files have non-square pixels (e.g. 704x480 or 720x480). These need proper scaling.

Many HD camcorder files have non-square pixels even though they are 16x9 (e.g. 960x720, 1440x1080).

Most broadcast and Blu-Ray HD files have square pixels (e.g. 1280x720 or 1920x1080).

So yes, more source detail is required.

I converted the same video to 720x480 to save HDD space and now the ratio changed and it doesnt fill the HDTV. screen. Is it because 16:9 is only for 720p and 1080p?

Its weird because I also have an avi. and the resolution is 640x352 and the ratio is 16:9 and fills the screen. How do I get my videos to 16:9?

OK, I'll assume your AVC player only plays in square pixel.

1920x1080 is 16x9 aspect when viewed as square pixel

720x480 is 3x2 (13.5x9) aspect when viewed as square pixel. If it was flagged as 16x9, many players would horizontally stretch it for 16x9 display but yours is flagged 3x2 square pixel.

640x352 is 16.36x9 when viewed square pixel but is flagged 16x9 so many players would horizontally scale it to 16x9.

The 16:9 square pixel conversion for 480 lines is 853.3 but 853 is not divisible by 16. The closest option is 848x480 which would slightly squeeze the picture horizontally and show about 6 pixels pillarbox either side when enlarged to 1920x1080.

Instead of 848x480, many people use 720x400 for xvid which will play on many DVD players. 720x400 scaled sqaure pixel to 1920 would show slight letterbox.
