Hi guys, I'm thinking about buying the Samsung Vibrant (That's the US Tmobile version of the Galaxy S for clarification) and I noticed that it can play 720P and it has a WVGA screen. These days, a lot of phones are capable of technically "playing" 720P video but none, even including the almighty retina display, have hd capable screens. But I was just wondering, besides being able to play its own recordings, what is the point of watching HD videos on a screen that really can only play 450P (keeping to true wide screen aspect ratio of course)? It just uses more battery and system resources to decode the higher res video when the end result is identical. Watching 720P on a WVGA screen is tantamount to hooking up a Bluray player to a non-HD screen. What's the point?
And yes, I'm well aware of the phone's DLNA capabilities.
Beats re-encoding right?
I think because the screen is so small and the resolution is high, it gives you the illusion of watching something in HD. If you compare a DVD rip to a 720p video on Galaxy, you'll definitely notice a difference. And the Super AMOLED screen helps too
Yeah, I can see how it's more convenient to just throw it on there raw but it seems like I'd rather take the effort to make it a lower resolution to save space on the phone if it looks the same either way?
And is there really that noticeable of a difference? I'd love it if someone could show a comparison picture between the same scene of a video in 720p and 480p on the galaxy screen to see if it's significant. Also, it might be possible that android is using sub-pixel interpolation to emulate the higher resolution.
Well the screen is a tiny bit wider than the 720 pixels you get from a DVD. Better to downsize than upsize, especially on such a sharp screen! I find that when watching DVD quality videos on a laptop, you notice the artefacts and low quality less than on the phone.

720p is actually 1280x720 pixels, the phone has 800x480, there should be no difference to your eyes from viewing a high quality 480p video or a 720p.... People are probably comparing a low quality 480p DVDrip with a high quality 720p video, and that's why they are seeing a difference (color quality and sharpness play a big roll here). It makes no sense to watch HD content on the phone, a good 480p will look just as good and will take less processing power...
Thank you!

That is exactly what I've been saying this entire time! And since true 480p is actually 848 x 480, I've been encoding all my videos to 800 x 450 because my hd2's screen just can't take proper advantage of hd. Somewhat ironic considering its name. It requires less processing power and with good encoding, you lose very little quality compared to the original video. This whole 720P playback seems to be just another marketing ploy like the megapixel battle was. Just another bullet to throw on the spec sheet.
Update: If anyone reading this would like to test the quality difference between video resolutions on their respective HD capable device, here's a great test clip in several resolutions: http://www.bigbuckbunny.org/index.php/download/
Yes, it's ideal to reencode to maximize size usage if you're gonna keep the video on the memory for a period of time.
However, for those HD videos that you've downloaded, and you have no wish to dl a SD version of it just for portable viewing, and it's something that you're gonna watch once and delete, that's where the functionality to view HD media comes in handy.
In short, it's more convenient to have the ability than to do without it.

Hmmm good point. I suppose I'll just chalk it up to "convenient but not very practical." Thanks for all the great replies!
Very true and i believe the 720p which actually is for the video output..i just got the Nokia CA75-U cable and the 720p video playback is amazing on big screen TV.

That's not 720p, it's standard definition tv.

Yes, but I meant DVD resolution which has 720 pixels in width.
Besides, my entire collection is in 720p HD.. So when I'm going out and want a movie/series with me for boring times when travelling, it's nice to not have to convert them/re-download a lesser quality rip.
I also think I see a difference, tested with a SD-rip of Top Gear vs HD-rip of it. But might just be in my mind Seems sharper though.
You kow, videos encodings are at different resolutions for luminance and chrominance data.
Color data is often half or quarter the resolution of the actual video resolution.
A properly encoded 1280x720 video will look better than the same encoded at 840x480.
Considering the processing power, when video decoding and scaling are done by hardware, power consumption will be almost identical.

Not practical only for you maybe, but different people have different needs. Don't assume that you can decide for the whole world.
Hi all,
If all goes well, i will get my One this tuesday.
since im going on holiday short after i would like to put some movies and tv series on it to watch.
I would like to convert these movies/series to the best quality vs quantity ratio.
I could possibly leave it at full HD settings, but then the 32 GB will be full in no time.
So i can live with somewhat less quality (not to bad, i still want to enjoy the movie ).
My question is what do you guys recommend for convertion settings for video files to play back at the HTC One?
Thx!
I'd suggest using HandBrake with the iPhone 4 preset (seriously) and perhaps adjusting the resolution to match - not that 720p or 1280x720 would look any worse for wear on a 1080p panel, it'll scale up nicely and you end up with much smaller filesizes for the resulting container.
I'm sure someone will work on a new(er) preset for these newfangled 1080p screen devices but really, considering the increased size of the resulting encoded container/file (MP4 being the most preferred on smartphones but you can use MKV as well depending on your media player of choice; my recommendation is still for MX Player), there doesn't seem to be any real need to create full blown 1080p versions of material when you can encode to 720p resolution and they'll be significantly smaller while still looking fantastic on those displays.
I'd rather have 10 720p movies on a 32GB device that give me something to choose from than 1 or 2 1080p movies that take up nearly as much space, but that's just me.

exactly my point. Im using handbrake my self aswell and MX player is likely to be one of the first apps to install so i can use this info!
Thx!
Other suggestions are always welcome!
I've been watching Torchwood, and the first eight episodes were all excellent quality. It's available in many countries I believe, but my Unblock-Us happened to be set to USA when I watched it.
Anyway, season 1 episode 9, entitled "Random Shoes", played inexplicably in a 4:3 format on my HDTV with black bars on either side. The picture was not distorted or anything so it was clearly pan-and-scan type source material. I have double checked - in Firefox on my desktop I get the same too. However if I play it on my Nexus 7 it does give me a proper 16:9 aspect ratio. The moment I push it to Chromecast though I get 4:3 again on TV. Episodes 8 and 10 are 16:9 on all devices.
I wonder if this is just a glitch with Netflix's servers then? Maybe there are some sporadic episodes here & there where it serves up the wrong media on certain devices.
Interestingly, when I switched Unblock-Us to UK, this episode played in nice crisp 16:9 HD again. I also noticed that on the US site I can add closed captions to Torchwood (really helpful when I can't understand heavy accents speaking softly against background music), but on the UK site I cannot.
It's an issue at Netflix..
I have had the same issue when watching "Dead Like Me". Some episodes player properly and then a few played incorrectly.

Netflix issue, not Chromecast. I came across this thread when Random Shoes randomly played in 4:3 on my LG Blu-Ray player.
Yeah, I'm finding that some of the Netflix titles are encoded improperly...
Does anyone know if there's a way to report an issue with a video to Netflix?
I'm new to Netflix and I looked around but maybe I missed something obvious.
They actually take phone calls. I phoned in to report terrible subtitles for "Arrow".

Hello . I watch online video a lot from differed website but all show in 16:9 aspect ratio maybe is there any program to watch in 4:3 i relay wanna watch in full scream i try vlc player stream from url but no luck. ?

bump any suggestion?
If the video being streamed is in 16:9, there's nothing you can really do.

Does anyone know why when recording video with the 1:1 aspect ratio we're only allowed to record at 1080p 30fps? Is there a logical reason that I'm unaware of? I had a galaxy s9 prior to this, and I thought we were able to record at 1080p 60fps. I tend to record with this aspect ratio, as it's convenient for posting to Instagram. It would be a pain to record 1080p 60fps at 9:16, and then crop it post, though I can't tell if, when you would crop it, it down-rates it to 30fps somehow.
