If ATV3 looks at "profile 4.1" and doesn't even try, then it's probably not the right device for me. I've gone through great pains to pick h264 blu-ray content, and most of it imports into iTunes properly, but as with many things bluray, bitrates can spike past 25mbps. If iTunes doesn't get in the way and does stream this content to ATV3, does ATV3 handle brief spikes > 25mbps Ok, or will it also just throw up its hands and give me some unsupported media format error?īefore I buy the thing, I want to get an idea how much of my existing media library will actually play on it. If these files import into iTunes OK, and they do sync and play smoothly on the new iPad, should I expect that iTunes will try to stream them to ATV3? Or will iTunes simply get in the way and say "sorry it's 4.1 and I see that it might be over 25mbps so I'm just going to say 'device not supported' " ?Ģ. I really do not want to re-encode just to drop the spikes.ġ. basically average bitrate of about 20 mbps, but with max bitrates spiking to ~ 30-32 mbps. What I'd like to do is, get an ATV3 and in theory stream this video to my receiver with ATV3 as the playback device. I occasionally sync some of this (stuff like the old Twilight Zone series on BD) over to my iPad when going on short trips. I have a ton of h264 content from my bluray library that I keep on a home server I changed the container to mp4 but the original video is untouched, and imports into iTunes OK. Lookahead Sets the number of frames to use for mb-tree ratecontrol and vbv-lookahead. Bitrate Variance Allowed deviation from the target bitrate or filesize. What I wanted to find out is, does the new ATV practically go any higher, and if so, about how much headroom? VBV Initial Buffer The initial occupancy of the VBV buffer. you the user have to set it up correctly for best results.I know that the new AppleTV supports HiP 4.0 in 1080p up to 25 megabits/second. Thus, you'll get poorer quality output in the case that it doesn't need done. So if you turn on de-interlace, every frame is de-interlaced regardless of whether it needs it or not. As far as I know, they don't have interlace detection filtering. XMedia Recode output Overall bit rate mode CBR Thread Tools Thread 8th Aug 2019 23:55 1 zglloo Member Aug 2019 I have been trying to speed up transcoding MP4 or MPEG-TS files, but I found that the total bit rate of the output is still VBR. You won't get better quality as the filters protect against quality loss to begin with. ![]() If you know your sources are defiantly progressive, you can just turn the 2 filters off and gain the speed back. We've decided that the performance hit is worth it as users then don't have to understand what this is. If you don't de-interlace a interlaced source, you'll get interlacing artefacts in the output which are nasty. If it does need de-interlaced then it's a moot point. With XMedia Recode you can easily convert nearly all film and music files in the format you want. If it doesn't need de-interlaced, it won't do anything. 1 day ago &0183 &32 XMedia Recode is a free video and audio converter. When I convert a video file I always set bitrate the same as the original file. Interlace detection looks at your source and decides whether it needs de-interlaced or not. Results 1 to 7 of 7 xmediarecode - getting the bitrate I want Thread Tools Thread 2nd Feb 2011 08:20 1 pooksahib Member Dec 2010 UK Hi. (That said that's with one sample file on one sample system but in general, given both apps use the same underlying encoder and likely same decoder, it should be within a pretty small gap) In my own testing HandBrake win's out but is more often than not within a margin of error or very slightly faster. Quality:20 (increase it for smaller size or use 2-pass encoding with a fixed bitrate) Quote. Speeds in HandBrake vs xMedia, like of like on settings, should be very similar. Note, I don't believe xMedia has those same filters available so you'd probably have to switch to yadif on both sides to have equivalence. I went from 6 channel FLAC to 6 channel AAC at 384 kbps. ![]() ![]() The problem is that I may have set the audio quality a bit too low. The "Fast 480p30" preset in HandBrake is essentially Quality RF 20, x264, fast preset, 3.1 with Interlace Detection and Decomb turned on and a hard cap of 480p resolution at 30fps I recently started re-encoding some of my high bit rate videos to save space using Handbrake. Turn off Interlace detection and Decomb on the filters tab and you'll probably find any difference disappears all other settings equals. The reason HandBrake is likely running slower is that there are a 2 filters that are default on which won't be in xMedia.
