- UnisonRuss - 2009-01-21 There is nothing we can do upgrading hardware wise, unless we all stripped the ATV bare and made our own box...that would be time consuming and costly though. it will have to be the developers that come up with a way to utilize the GPU somehow, or cut down on CPU usage even further through future updates. - sircube - 2009-01-21 randywaterhouse Wrote:well, it's a transcode process so yes, theoretically you lose quality, but you'll still end up with very good quality Further more you can try mkv2vob. Simple interface. e.g. 8GB MKV with Resolution : 1280x688 Video Bitrate : 7580 kbps Audio Specs : Mayan AC3 5.1 @ 640 kbps can be relative fast converted to vob or other container using "just" mpeg-2 encode (1.5 hours on my dual core T61p). File size grows 10% but disk space normally isn't a problem if you're in the highdef world. Point is that MPEG-2 requires least processing that's why I go with it. 720p files play smoothly. I still keep the original mkv hoping for a GPU acceleration some point in time. - Fede84 - 2009-01-21 sircube Wrote:Further more you can try mkv2vob. Simple interface. But in this way i have a loss of quality or not? - UnisonRuss - 2009-01-21 Are you transcoding the video into the VOB or just remuxing? That makes a big difference! If you are transcoding using this program it is the same as encoding the file using Handbrake...but if you are just remuxing and the 720P content is playing smoothly then you are on to something! ...I must do some testing now - UnisonRuss - 2009-01-22 Same playback with the remuxed files as I suspected...I will add however that since the new launcher 720P files are playing back almost flawlessly, just some jitters on pan shots, and dropped frames here and there, definitely a noticeable difference though! Keep up the good work guys, soon ATV will do what we want it to do - Fede84 - 2009-01-22 UnisonRuss Wrote:Same playback with the remuxed files as I suspected...I will add however that since the new launcher 720P files are playing back almost flawlessly, just some jitters on pan shots, and dropped frames here and there, definitely a noticeable difference though! Keep up the good work guys, soon ATV will do what we want it to do Yes, it's true that with the new launcher playng it's a little better.. I've try MKV2VOB with no transcoding and one audio track, this are the result: MKV: Code: *** MediaInfo Mac // Plain text file report Code: *** MediaInfo Mac // Plain text file report - UnisonRuss - 2009-01-22 Fede84 Wrote:Yes, it's true that with the new launcher playng it's a little better.. I've try MKV2VOB with no transcoding and one audio track, this are the result: The level changed; L=Level and 4.1 is High Profile while 3.1 is Main Profile...the higher level the harder it is to playback...theoretically. My new theory is that it may be the audio stream the file has...AC3 may make it harder to playback smoothly because of extra decoding involved. I have extracted a AC3 stream and muxed the video file and new AAC file into a MP4...I am going to watch it tonight and see how it plays. - Fede84 - 2009-01-22 ok, i'll wait your opinion.. if it works you can tell me how i can do that? Thx - sircube - 2009-01-22 Interesting so see that codec profile changes by different muxing to container. However... I meant another tool for easy re-encoding purpose. Sorry, miracle is not something for today. For handling high-bitrate files like in my example I see no other choice than using less resource demanding encode. Reducing the sound channels/encode and therefore complexity might help you with less glitches for files around 5000 Kbps. Lets see. - Fede84 - 2009-01-22 UnisonRuss Wrote:The level changed; L=Level and 4.1 is High Profile while 3.1 is Main Profile...the higher level the harder it is to playback...theoretically.Some new for you theory? i'm intrested in that - UnisonRuss - 2009-01-22 From what I can tell the audio/container has made no big difference...the video plays slightly better with 2.0 audio and an MP4 container, but not good enough to go through all of the trouble. Either we just wait it out for a new launcher that helps the video playback even more and deal with the glitchy video, or encode the 720P content to a smaller resolution/file size and not deal with the glitchy video until we know it's resolved - Fede84 - 2009-01-23 A question: It's better i upddate the Apple TV FW at 2.3 or it's better i leave the FW to 2.1?? To have improvment for MKV files.. Thx - UnisonRuss - 2009-01-23 I have only used 2.3 so I have no basis of comparison, but MKV files (for the most part) are playing pretty good since the newest launcher - nikiiv - 2009-01-23 What good the launcher can bring into mkv playback.. just wondering - UnisonRuss - 2009-01-24 I believe it has to do with CPU usage...the less usage with the program the more dedicated to performance... |
