Improving video compression

Is there a reason I can't maintain the quality of a video when I upload it to my site? I start with fantastic videos but by the time They are done uploading and being converted, they look like caca.

About the only thing you can change in the video upload flash mod is the bit rate. It defaults to 512. When I max it to the 2048 setting, processing time goes off the charts and it takes forever.

I've been waiting now for more than 10 minutes to process a 275 meg html5 video file....

In the end, there's absolutely no difference between the two

I'm thinking I can make a change here to improve the quality but have no idea how to proceed.

=========================

if(empty($GLOBALS['sModule'])) $GLOBALS['sModule'] = "video";
$GLOBALS['sModuleUrl'] = $GLOBALS['sModulesUrl'] . $GLOBALS['sModule'] . "/";
$GLOBALS['sFilesDir'] = "files/";
$GLOBALS['sFilesUrl'] = $GLOBALS['sModuleUrl'] . $GLOBALS['sFilesDir'];
$GLOBALS['sFilesPath'] = $GLOBALS['sModulesPath'] . $GLOBALS['sModule'] . "/" . $GLOBALS['sFilesDir'];
$GLOBALS['sServerApp'] = "video";
$GLOBALS['sStreamsFolder'] = "streams/";
$GLOBALS['aConvertTmpls'] = array(
    "playX264" => $GLOBALS['sFfmpegPath'] . " -y -i #input# -b:v #bitrate#k -vcodec libx264 -s #size# #audio_options# #output#",
    "play" => $GLOBALS['sFfmpegPath'] . " -y -i #input# -r 25 -b:v #bitrate#k -s #size# #audio_options# #output#",
    "image" => $GLOBALS['sFfmpegPath'] . " -y -i #input# #size# -ss #second# -vframes 1 -an -f image2 #output#",
);

Just out of curiosity, what version of ffmpeg does Dolphin use?

admin - tools - host tools  ffmpeg output with version info ....  and yes you can change the conversion in that file.

you can also use  modules - flash modules - video - settings and change the bit rate and frame rate in there.

you can also change an xml file or two and add higher bit rates for the drop down in flash apps  video...  

Moral of the story is if you want HD videos you need powerful processors along with higher RAM. In case of high volume of traffic it will be a disaster to let the video processed in HD quality unless you have a cluster of servers which are processing large amount of files and also serving them to the users.

My site is very low traffic. It's a rarity when more than 1 or 2 people are watching videos at the same time. I am fully aware of the need for processing power.

LOL 0.10? That version is so old, they don't even list it anymore (can anyone say Feb 2012?). Why on earth has this file not been updated yet? Current version is 2.6.3 !!!!! I would understand that if it actually cost money but the damned thing is a free download.

Obviously things have changed bandwidth and CPU wise in 4 years. Most people can support better options now. I think it's a good time to update this file and add some of the new functionality into Dolphin with a better admin page for the videos where we could take advantage of some of the newer stuff. HELL my videos look pretty good if you compare them to what we were looking at on YouTube 4 years ago!@

Yes need to ask alex about it. I was wondering if we replace current version with the latest 2.6.3, will it work? cause the current version was created on 23rd July 2013. I don't know if it was modified for dolphin.

AlexT has already stated that 7.2 will ship with a new ffmpeg.  One can also upgrade an existing ffmpeg including 7.0.9 sites.
