Handbrake doesn't do it, but ffmpeg should be able to handle it just fine using -acodec copy and -vcodec copy

Re: Want to buy new system for handbrake

Pure x264 starts leveling off at 8 cores, but anything up to that will scale almost linearly. However, not all of the filters (decombing, etc) are fully multithreaded, so if you use them, they will serve as a bottleneck moreso than x264 itself. Decoding via ffmpeg is also single-threaded and has pop...

Re: Some encoding questions

Many devices don't have any way of selecting a secondary track, so putting the most compatible track (AAC) first is a good idea if you plan on using devices that don't support AC3. Everything defaults to using the first track, so you can either put AC3 passthru first and risk borking sound on device...

Re: Some encoding questions

I'll try to field some of these, but anyone is welcome to chime in and correct/expand on anything I say: 2. You want AAC as the first soundtrack because it is more compatible with playback devices, as you've found. AC3 passthru is nice to have in case you ever get a 5.1 system, but if you're happy w...

Re: Disappointed to see target file size go

However, these programs all have a much steeper learning curve than HandBrake and lack HB's fantastic cros...

Re: Disappointed to see target file size go

@match The general equation for filesize is: size = bitrate x time solved for bitrate, we have: bitrate = size (in kilo bits ) / time (in seconds) <-- there are 8 bits in a byte, so we need to multiply our size in bytes by 8 to get it in bits So, for a standard def, 22-min TV show at a desired final...

Re: Disappointed to see target file size go

I also use(d) target file size quite a bit and hate to see it go, but average bitrate is still going to be around, right? I know it's an added hassle to divide your desired filesize by the time of the video to get the required average bitrate, but at least it's an option.

Re: How to reduce "mosquito-noise"?

I think your biggest problem is that you seem to be using the ffmpeg mp4 encoder, which is extremely fast but looks terrible, rather than x264 (slower, but much better quality). If you switch to something like the 'high profile' preset, you should end up with a better-looking file without the "mosqu...

Re: Huge size variations with similar content

Since it's MST3K, you're also dealing with a lot of older movies, so variations in film graininess could be involved. You might try messing with denoise settings and see if that evens things out.

Re: Blocks appear in pure black areas of a video after encod

You might consider adjusting some of your advanced x264 options, such as increasing the subme and/or adjusting the psy-rd/trellis settings. While psy-trellis is often considered a no-no for animation, it can help with blocking in grainy areas and gradients, so you might give it a try on a short test...

Re: Ripping TV shows... interlacing?

The easiest/safest thing is to turn decombing and detelecine back on and see if that fixes you up. If that doesn't fix all of the artifacting, you might try turning deinterlacing on instead.

Re: DeInterlacing issue, & noise turning into to block artif

Yeah, you're probably right; denoise certainly sounds like it would be more appropriate :lol: . Removing grain is not something I've ever wanted to do, specifically, but I've noticed that it has been a side effect when I've turned up deblocking, which is why I mention it.

Re: DeInterlacing issue, & noise turning into to block artif

I don't know what to tell you about the interlacing thing, but for the grain issue, you could try either using deblocking to kill the grain entirely or psy-trellis (I've had good luck setting it around 0.5) to keep the grain without the blocking.

If speed is more important to you than efficiency (i.e., better quality at a given bitrate), you could turn down some of the advanced options to faster/lower-quality settings, such as dropping the subme setting (the most direct speed:quality tradeoff, IIRC), no trellis, etc. If you're using Constant...

Re: AC3 passthru is picked up as AAC

If you're going to be remuxing everything into mkvs anyway, you should be able to re-order the audio tracks so that AC3 is the default, or even remove the AAC track entirely at the same time.

It's sounding more and more to me like there's not actually a problem with your encodings, you just need to figure out how to tell your WD Live to choose a different audio track.

Re: AC3 passthru is picked up as AAC

One possibility is that you used the AppleTV preset for you encodings (did you?), which automatically includes a passthru AC3 soundtrack and an encoded AAC version. If this is the case, your device may be defaulting to the AAC soundtrack instead of the AC3 one. We can't really tell either way from t...
