Evo 4G


iPhone 4


Any developers out there can figure out what the hell is going on? Lol. I know the iPhone is capable, but what's holding the Evo 4G back? Hardware? I mean I hope it's not for such a technical beast. Software? Lens? Ugh.

Considering the gs out performs the evo this isn't a big surprise.

It's probably a few reasons, first being the device relies on a slow sd card (out of the box) vs fast internal memory. Meaning they had to be careful with file size and how much data got pushed from the camera to the card. better sensor, better lens, less compression etc.. The Evo also records in a ****ty codec

Software. Also note that the iPhone does technically record 20+ fps video, it is doubling frames, so a lot of the time its only actually capturing 15-20fps and then doubling some of the frames. Once we get full kernel source, we can overclock the camera chip the same way we kinda did for the Nexus and improve the bitrate, audio quality, and video fps. See this thread: http://forum.xda-developers.com/showthread.php?t=698287

I read somewhere that HTC was doing a huge amount of compressing of the video that is recorded. It has to be something like that in my opinion.

The iphone 4 has a back-lit camera sensor. That is likely helping a lot for this indoor video. I have also read that the evo4g compresses video a lot.

Dam, makes the Evo look like sh1t lol.

The Evo also has a backlit sensor. Look up the Omnivision OV8810 if you wan't more info on it, its the same sensor used in the Incredible. The only difference is since the iPhone is only a 5mp sensor, the pixels are ever so slightly larger, which will help with low light performance a little, but not drastically on these sensors. Its mostly software, since both of these sensors are so similar being backlit and whatnot

Look at the codecs... iPhone4 is h264 (10) (what we think of as mp4 on desktop) and EVO is H264 (2) which is horribly low bitrate, thus the blockyness.

Hopefully Geniusdog254 is right and we can pull a bit better fps out of it, but I don't think we're going to be able to do much about the low light abilities, the iphone4 has a better sensor and optics.

I didn't realize htc had a backlit sensor. Good. Hopefully they can get their software to be worthy of it.

NM, said above.
