Conversely, you also see that while the CBR encoder allocated most of the bits evenly over the entire file, the VBR stream allocated much more of the bits to the hard-to-encode region at the end of the file. With these two patterns in mind, ask yourself two questions. Then consider, which file would you rather stream to a viewer watching on a 3G connection? Though not evident from our experiments, CBR encodes infrequently produce transient quality drops when the encoder sacrifices short-term quality to meet the target bitrates.
For this reason, most producers avoid CBR whenever possible. Most digital broadcast streams are encoded using CBR because the streams are transmitted through fixed bandwidth connections with a low tolerance for stream variations. During the early years of streaming, when producers attempted to deliver video to Today, because the average video download speed in the U. In a live workflow , you have to choose in your on-site streaming encoder and your transcoder. In video on demand VOD workflows, you have to choose when encoding the files for upload to your streaming server.
Though one-pass VBR encoding is possible, VBR is most effective when the encoder can scan the entire file and identify the hard-to-encode and easy-to-encode regions. In addition, when encoding onsite for streaming to the cloud for transcoding and packaging , producers often work with tight outbound bandwidth constraints. During CBR encoding, the bitrate or the number of bits per second is kept the same throughout the encoding process.
Constant bit rate CBR encoding persists the set data rate to your setting over the whole video clip. CBR encoding does not optimize media files for quality but will save you storage space. Use CBR only if your clip contains a similar motion level across the entire duration.
Posts Website. Knowledge Base Find your answers here. Ok, ok. I was just paraphrasing what the guy at r3mix. I would think the file will be the same as a VBR file so it's pretty standard. Specifying the average bitrate is an encoder-side trick.
It probably still outputs normal frames. Is ABR "standard"? VBR is currently under heavy development. Right now it can often result in too much compression. I do not recommend using VBR. But if you must, you should at least use a minimum bitrate of kbps.
It goes from 0 to 9, obviously. IIRC, the guy at r3mix. If you're using VBR, you'll probably want to use "1". As a side note, -q is sort-of explained in the documentation now Well, there's always some golden eared god who can distinguish the sound of a fly sneezing on the other side of the world, but yeah, a kbps LAME rip is near indistinguishable. In a blind listening test you might be able to notice a difference with very specific hard-to-encode passages, but 1 most people can't and 2 a difference doesn't necessarily mean one is better than the other, subjectively speaking.
That is pretty well the options I was using except. I could split the track into two peices but in principle isn't this what VBR is supposed to handle?
Different complexities within a track should be encoded at different bitrates. Also winamp sucks at telling you what bitrate it is currently decoding at. I guess I'll fidel with it a bit more. Try unchecking something like "show average bitrate". What this does is show the average of every frames played so far, so it's normal that if you skip some the result will be different.
If you uncheck it, you'll see rapidly fluctuating numbers but "normal" numbers like , , , Not sure about this however.
There is no option to "un"average the display of bitrates in my version of winamp v2. I think winamp does average them sometimes over a certain period of time. Just not sure what that period is. I'll have to check this at home.
The option was there some time ago in the input plugin settings I think. In case anyone was interested, I tried a few different settings and ended up encoding everything VBR, with Lame 3. I see a lot of people are using Winamp for playback IIRC, Winamp had some decoding bugs in it, but the major one was fixed in 2.
