720p Vs 480p

[Bartolome Beacham]

When480p30 is broadcast on air, it is frame doubled then interlaced to 480i60. In case of 480p24, it is processed using the 3:2 pulldown technique to 480i60. In both cases the spatial resolution doesn't change, but the conversion to a interlaced format allows a direct digital to analog conversion for eventual broadcast on the analog television network.

I'm trying to export a project I made, but at the export screen it keeps saying the source is 480p, and when exporting it outputs 480p. When I right click the track and go to properties, it then says it's 1080p, which it is. Any idea how I can make it output 1080p?

My recommendation for this is always the TV-Out interlacing preset, though you may want to substitute the interlacing pass (which provide the scanlines) with an alternative. I use scanlines-sine-abs with it.

I was testing with a CRT monitor and 480p output, on the monitors the mask is invisible, so I used some of the CRT shaders to give a TV effect, Hyllian and Lottes have a good effect, sometimes I had to disable the scanline.

At this resolution I prefer just dead simple scanlines: one row of fully black pixels followed by a row of the original 240p image. Turn on integer scaling (2x) and use the interger scanlines preset under the scanlines folder.

I just bought a hd link clone on amazon for my xbox (pal tsop 1.4 motherboard, the bios was flashed in order to get hd mods) because my TV doesn't have a component port, only hdmi and rca, the cable hd link works well at 720p and 1080i signals, but doesn't at all at 480i/480p , the screen is flickering as f*** at thoses signals. I figured it came from this cheap cable, so i send it back to amazon, and order a component cable + a component to hdmi converter.

Just received it, tried it, and it does the exact same thing, i was thinking that it was either bad luck or i was doing something wrong, so i tried that on a older tv that have component port and hdmi, tested both ports, and it worked with no problem at all !!

Other's have had problems on some high-definition TV sets when using these HD Link adapters (Xbox-to-HDMI adapters by Pound Technology, Hyperkin or clones of them) showing a blank screen every few seconds. Not sure if it was only while displaying 480i/480p or 720p and 1080i as well.

I'm wondering if that could come from a conflict with the 4/3 ratio aspect provided by the xbox (and upscaled by thoses cables?), most of the recents Sony TV have the ability to force the 4/3 to widescreen, i turned off all screen ratio options and factory reset the tv for try, but nothing changed.

First up is DOS/Win98 PC on a 17inch NEC MultiSync 75 from 2000. I ended up getting this monitor after being really not satisfied with any option to run DOS games on a modern monitor. Everything just being sampled wrong in VGA mode 13h, which is a pre-output linedoubled 320x200, taking 720 samples of 640 output pixels, sometimes mangling the aspect ratio as well. It really just looks so much better on a CRT, and as a bonus proper 640x480 stuff looks great with beautiful scanlines.

I run OSSC 480p at Line2x, which outputs to 960p, with the upsample2x option on, which takes twice as many samples per line. For VGA timing needs to be set to DTV to correctly display PAR for Dreamcast.

Undertale uses the 480p resolution, but the pixels there are scaled by 200%. But how do they do that? I use 32 x 32 pixel arts, and use 480p resolution, but the pixels there look so small. So how did Undertale manage to scale the pixels by 200%, while being 480p?

Hi lads, im using an av2hdmi converter on a samsung 4k tv and i can only get 576i on 50hz. 480p is greyed out. My wii is bought from a thrift store but im pretty sure its legit, it has the gamecube ports. Its version is 4.3e. if i put it at 480i then the screen tears and is discoloured, tho strangely when i run ntsc games through usbloader its normal. Anyways, any more info i can give in order to r solve my issue and get 480p?

@panos21sonic It seems like you are using composite AV cables for the Wii (the yellow one). These cables cannot handle 480p. You can get a HDMI adapter specifically for the Wii, such as this one -Adapter-hdmi1080p-Connect... .These make use of the component output from the Wii instead of composite. This allows it to use 480p

Well you CAN make rough assumptions. For a live action film a bit-rate of 3-8 Mbit/s is very advisable at 1080p. At 3Mbit/s you will very likely have noticable artifacts, thats usually an advisable bitrate for 720p video.A file at SD resolution 480p/567p that is around 4GB in size you probably deal with a DVD that wasn't trans-coded for archiving.

Generally I would probably go with the 1080p with less bitrate if its smaller in size, just because its smaller in size and its very likely that on a 1080p monitor/TV the video will not look worse than the upscaled DVD.

There is no concrete answer to this. It depends entirely on the content of the video. Video compression effectively looks for patterns in video. If lots of patterns can be found, then high compression can be achieved with high resolution and low but rate. If the video is hard to find patterns though, then high compression results in altering the video to make patterns and this produces artifacts that distort the video.
