Has it been confirmed that a higher micro SD class will yield better 720p recording?

It just occurred to me a bit ago that this could be why my 720p videos suck more then the next lesser resolution.
Sent from my PC36100 using XDA App

I have a class 6 and havent seen an improvement over class 2, the video records at a slower speed than your card can handle so it shouldn't matter,
I can backup roms quicker though

thank you for the reply.
so the crappy 720p video was a marketing scam or what?
i love this phone, and i thought the video shot very good till i noticed that it wasnt set to 720p, so i bumped it up thinking it would look even better....lol it looks worse.

Umm lets see:
1280*720 = 921'600 pixels
Assume that the camera records @ 8 bpp (24 bit color) * 24 fps = 921'600 * 24 * 24 = 530'841'600 bps... that is 531 Mbps or 63.28 MB/s.
So theoretically, yes a higher speed media would yield a better quality (note that the calculations above do not take in consideration the CPU and the compression, also notice that the sound is not included). Even at the crappy 12 fps, the required sustained speed is still higher than any microsd card out there.

agreed i have a class 6 micro sd n the video quality still sucks

I think the various codecs and compression make these numbers much less significant, but since I don't know the exact numbers I'm would have to speculate on how much the sd card speed matters.
I have heard that for some cameras the sd card speed can affect video capture.
Probably the way the phone handles the compression is the major cause of choppiness for our phones though.

they compress the video so the crappy class 2 cards the phones come with can keep up, someone would have to change the codec so it doesn't compress it as much.

What quality/settings for converting Blu-Rays to Play on Note 10.1 2014

So I just converted my first blu-ray to play on the tablet and it looks a little pixelated. Did I use the wrong settings or is it the program I'm using for conversation?
the outputted .mp4 has the following settings:
Video
Frame Width - 1920
Frame Height - 1072
Data Rate - 2496kbps
total bitrate - 2624kbps
frame rate - 24 fps
Audio
bitrate - 127kbps
channels 2
audio sample - 48hhz
I set the program to export for Android Tablets 1080P. They don't currently have the Samsung 2014 as a listed model yet, I did see the Nexus 10 which has the same resolution but oddly enough it wanted to do 1280 x 720 res.

Why convert?

space limit?...
he/she is not providing enough information about encoding settings... no program name, etc...
2624kbps for 1080p file?...

bump up your bitrate. 2500 is kinda low. 3000 is acceptable imo if you're concerned with space. I only use 2500 for videos for my daughter. 4 to 5K should give you a 3-5GB file depending on movie length and how well it can compress.

To Answer your question I'm using Pavtube Blu-Ray Ripper. Looks like its defaulting the bitrate to 2500 (for the target) I'll try raising it and see how that works. Thanks.

Yea what he said ^^^

If your going to use low bitrates then your better off using a resolution of 1280 instead of 1920, generally for good quality archiving any bitrate below 4000 for 1280p is considered low, for 1080p anything below 8000 is considered low, although there are other variables at play which can mean you use less or have to use more.
Obviously I'm not talking about viewing on a tablet when using the above but I thought it would help just to give you a general idea, with tablets having a smaller screen size its going to allow you to get away with a lower bitrate.
Your going to find it easier to get a bitrate close to 4000 when using a resolution of 1280 while maintaining a file size your happy with.
Unless you have a 50" tablet 1080p is overkill :laugh:
I would also recommend handbrake along with a little bit of reading of basic encoding.

Video Size

Hello guys i want to know why...?
I can download movies that are 720p with great quality like 600mb or less..
Why Android record videos maybe in 720p like 10 seconds and it have 150mb +/-
Mayba 10 seconds be 5mb? O less?

it has to do with the compression rates of the videos.
Some people think the 720p at 600mb are horrible quality but on the phones they look decent, since the screens are smaller, its hard to tell, but but on the bigger screens, not that great.
It just varies on the codec/compression/fps

Yea but as i said, movies 720p in TV or atleast 1080p not exceeds 1GB, and 1GB is like 5 minutes in phone. There is a way to change it?

A bluray movie in 1080p is in excess of 10GB for the video alone. Just because you can pirate heavily compressed videos around the 1GB mark doesn't mean this is the prime quality.
The phone will try to take the best quality video capture that the memory and CPU can handle. That's why you have such large sizes. You're supposed to export them to PC and then compress into whatever format you require.

Camera Time Limitations?

Does the S9/S9+ have a time limit on recording video? In particular, FHD Video @ 60FPS?
I know some phones have a 10 minute time limit and I also know that it has a 5 min time limit for 4K but what interests me is FHD @ 60 FPS for vlogging.

? The S7 had [email protected] Do you mean [email protected]? If so, there's a 10 minute limit per video.

Yes the S7 and S8 had FHD @ 60 FPS but I think they had a 10 minute limit as well.
Can anyone confirm if there is a time limit on FHD @ 60 FPS on the S9?

I just checked my s9+ and found out that:
4k 60fps has a 5 min limit
4k 30fps has a 10 min limit
Qhd 30 fps has no limit
Fhd 60 fps has a 10 min limit
Fhd 30 fps has no limit
18.5:9 ratio 30fps has no limit
1:1 ratio 30fps no limit as well
And hd 30 fps no limit (of course)...
Running s9+ exynos

How is this still a 'thing'? **** Samsung...

Fhd 30 fps is not unlimited. Only 40 min recordingtime.

FHD 30 frames is not unlimited at all! The limit is 40 min, I just tested it! (Tested on S9 plus)

No limit here, probably just how much space you have remaining that determines how long you can record for
Limit is shown like this 0:00/10:00 for 10 min limit
If no limit it just shows 0:00

Can someone with qualcom/usa version confirm video recording limits, if any, in different resolution/fps?

I have a bunch of $1 phones that can do unlimited FHD 1080/30. Very disappointed in scumsung. At least be honest and advertise it so ppl don't end up returning their POS s9/9+.

That is interesting. I bought a brandnew S9 Plus, tried to make a video from one hour, and it cutted it after 40 min on FHD 30 frames. Yes, it sais 00:00, but this isn't right. I would suggest you to also try it and see what happens. I am a concertpianist so its kind of important that there are no cuts. On my last concert the S9 cutted again after 40 min, so I think enough proof here. This is at least the case for the EU version.
PS I had 50 GB or so, because it was brandnew. Tested on day one, so this is not a memoryproblem.

I have no need to record 40 min videos so have never tried to go that long, and tbh I couldn't be bothered doing it for a test either
I think I would be using a proper video camera anyway if I was a concert pianist and needed to film my whole show, not a phone

The time limitation is to avoid additional taxes for being a video camera. I'm not sure what the actual time cut-off is, but standard DSLR Cameras are stuck at 20min or under in order to avoid being classified as such.
Make no mistake, the tech says we could record for hours. The tax code from 30 years ago says otherwise.
