Help can evo record in .mp4?

[thegame2388]

.3gp sounds so ghetto to me for some reason. not to mention, the 720p recording blows. the sound blows too. when will the update fix all this??? i was expecting like HD quality videos coming out of 720p. whats the best way to solve this issue? thx

Yes it can record mp4 h264 files, but you are limited to 800x480 resolution. At 720p you can only record to 3gp.

There apparently isn't a fix available for the sound. That's a hardware problem.

Ah but are you sure? I just tried recording in that format and it still spits out a .3gp file

Yeah I double checked. Still .3GP

Ok, no worries, here's the deal - when they talk about media (e.g., video) file formats, that really comes in three parts:

• the container
• the video codec
• the audio codec

Here's the info from one of my H.264 movies:

• H.264, 800 x 480, Millions (video codec)
• AMR Narrowband, Mono, 8.000 kHz (audio codec)
• 28.84 fps
• 2,910.56 kbit/s data rate

The .3gp file is just a container - it was designed a while ago for 3G phones, and that's maybe why it sounds ghetto. It can store:

• H.263 (the little vids, suitable for a web - originally the video-conferencing codec)
• H.264 (the modern, better, motion-optimized with fewer bits codec - considered the overall best for many applications, this is essentially MPEG 4 Part 10)
• or MPEG4 (this is really MPEG 4 Part 2 - very old - but we're stuck with it for 720p for now and we all hope that will update soon)

If you've got a Mac or a PC with QuickTime, these should play just fine. You may need to get Perian - The swiss-army knife of QuickTime components

If you've got Windows, depending on what codecs you have installed, these may play fine or not. (Many report video plays, but not audio, for example.) If not, the easiest thing is to just use VideoLAN - VLC media player - Open Source Multimedia Framework and Player (also works on Mac and Linux).

If you want to convert them to an mp4 or other popular file type, I personally use Squared 5 - MPEG Streamclip video converter for Mac and Windows - but - most people around here seem to use and prefer a program called handbrake (you'll need to google that or search this forum).

Anyway - the 3gp file type isn't really whacked - it's part of the MPEG4 stuff, too.

3GP and 3G2 - Wikipedia, the free encyclopedia

Hope this helps.

PS - the H.264 is so much better than the MPEG4 recording that I don't bother with 720p - and won't until they upgrade to that better codec.

PPS - that fps and bitrate in my example - actually matches what you'd find if you look at a the DVD-equivalent H.264 digital copy you get with Blu-ray movies - so, for H.264 and 480p, that bitrate is perfectly fine.

Interesting point - I always use a wired headset, everyone says it sounds fab - better than just using the phone.

I wonder, then, how decent the built-in mic (and it's circuitry) really is?

I've been assuming (definition: in denial that I'm hoping) that someday we might see a better codec using on the camcorder side, like AAC - the AMR one used now is _ok_ -- but it's just a plain-vanilla voice codec, nothing really decent.

In any case, the AMR codec is not great - but then you may be right, it may be a moot point if the hardware's really wrong.

I have a couple of comments and questions. 1st I looked up HTC EVO's specs and says it has the ability of using AAC audio. 2nd it cannot be a hardware problem because I downloaded an app called tape machine it records in AAC because the quality of the sound is really amazing. That brings me to my question of why the hell did they not implement this codec into the video recording. Any body herd now of any fix which there has to be one.

I also herd about a camera app called LGCamera which I used and gives you allot more camera settings and options including the ability to switch from AMR to AAC. I tried the AAC and it crahses the app. I talked to the developer and he said try it with the Amr which I did and stoped crashing. But what makes no sense it is that it works perfect for droid owners and he said he made this to work for the HD2 which the European version of the Evo. I looked up the specs that I found it very clearly says that audio it has AAC.

Heres the link to the specs
HTC EVO 4G

Let me know what you think.

Will run Android when hacked, maybe that's the difference.

Exactly, this is why we all hate the evo's video recording.

What will run Android wheb hacked.

 

[EarlyMon]

The HD2 is a Windows phone - note the link.

And it's available in the US - so it's not the European version of the Evo.

 

[Evo4sickness]

Yeah your right I ment Htc Desire Hd

 

[EarlyMon]

Ah - understand.

OK - the newer HTC phones have a number of internal changes for media not yet seen on our Evos, despite all running 2.2.1 - not-Froyo- or even Sense-related.

We're simply overdue for an update to give us what the other HTC phones have going for them.

Gingerbread has a complete change in the internal codec package, I'd expect the official release of that to solve things. Fingers crossed.

We're way overdue for an update anyway.

 

[Mr. Ed]

The Evo originally at release recorded audio quality was much better....then came along 2.2 update and stagefright....that killed it. Rooted users have roms to choose from that do not have stagefright.....and developers have re enabled aac and the recordings are pretty awesome.

 

[Evo4sickness]

Thats great to hear and I really also hope we see the AAC codec back. I dont ubderstand why they went backwards that just stupid.

 

[EarlyMon]

I don't recall seeing aac with video recording.???

 

[Evo4sickness]

I thought thats whay you were takling about.

 

[Mr. Ed]

I don't recall seeing aac with video recording.???

i will correct myself as i can't prove it...not without more work than i have time to do right now lol

the evo recorded clear audio at release,,
crystal clear, then after the update it went to crap
