![]() Source is DTS: Passthrough to prevent loss to lossy conversion.Source is AC3: Passthrough to prevent loss to lossy conversion.Now onto the main audio topic on what I'd personally do (note: I mainly watch movies on PC so I don't have any compatibility worries): Tuning these settings takes lots of experience and experimentation. As for a good resource, this website gives a brief explanation for advanced options, but is not meant for the layman. ![]() If you're familiar with advanced options, instead of using the default tuning you could tune the encoder to your specific content type. I'd maybe use the 10-bit encoder (better banding prevention) if compatibility is not an issue. Adjust the crf value depending on your tolerance. If I were forced to use x264, this is probably the (video) settings I would use. You're just filling in duplicates, or worse, rounding errors from non-perfect scaling.Ĭompletely depends on the person. If the output bitrate is set higher than the source, does audio upscale in a way that video does not? DTS is "better" than AC3 due to them usually having much higher bitrate. I can say this though: AAC, bitrate for bitrate, is better than AC3 and DTS. Most bitrate tests are done due to people interested in formats used for music. AC3/DTS exists because of the movie industry. Probably due to no one using AC3/DTS as an everyday audio format. I can't find anything online about bitrate equivalencies. I would never convert lossy codecs to another lossy codec. Why not keep things as it is then? It's the true definition of lossless.Īnyway, when converting AC3 or DTS to AAC, what bitrates should I be setting on Handbrake for AAC output?ĭepends on encoder, personal preference, and use case. Side question: Am I losing any picture quality when using the "Super HQ" presets? If there's any online resources y'all can point me towards that would help, because the official documentation doesn't help any. Additionally, if the output bitrate is set higher than the source, does audio upscale in a way that video does not? If not, is that bandwidth filled by what is there, or is it dead space outside of the source audio? I don't really care about file size, unless it's trimming languages I don't need.Īnyway, when converting AC3 or DTS to AAC, what bitrates should I be setting on Handbrake for AAC output? I know that 5.1 channel AC3 at 640 kbps is not the same as 5.1 channel AAC at 640 kbps, but I can't find anything online about bitrate equivalencies. When converting files, I'm trying to maintain as much of the original quality in both audio and video, but making them palatable to all my devices. I've been converting a bunch of files with mostly AC3 or DTS audio tracks.
