To recap, Norman wrote, "Speaking of video, IMO, the 8Mbps listed for 1080 <= 30p is maybe a bit tight for a lot of source material. Ironically, after calling out Norman on "unless he knows exactly," you then made some assumptions and observations in your next post. I can't think of anyone else here who regularly does varied test renders, uploads, downloads and file spec comparisons. Again, 160kbps AAC would be the normal standard for 44.1Khz/16-bit audio, with 192kbps being more than enough for 48Khz/16-bit audio.Ĥ) the "PCN" in Norman's handle is "Professional Computer Nerd," and Norman is likely the most technically proficient member of this forum. Unless you're recording to a dedicated audio recorder, you aren't getting more than 48Khz/16-bit (uncompressed)audio. To be blunt, the chances of your source audio being 96Khz/24-bit are fairly low.
320kbps would be the AAC settings to compress 96Khz/24-bit uncompressed audio. 192KHz is fine.ģa) The recommended 320kbps is a bit silly, actually. AAC is considered to retain more information than mp3 at the same bitrate.
mp4 audio at 160Khz is considered "CD Quality" audio. 192KHz will be your maximum bitrate in Hitfilm Express. Yes, there are limited bitrates available.
Yup I'm listing that twice.ģ) As has correctly noted, Hitfilm Express uses the built-in OS encoders.
Just saying.Ģc) You were told how to change the frame rate of an export preset. In this case you're in the wrong.Ģa) 60 fps is not "the recommended" frame rate for YouTube, it is an option. I need them to be at 60fps and they only go up to 30." Then yelled at when he answered that part of your question. You profanity has been removed.Ģ) In your second post of this thread, you wrote, "The presets don't match YouTube's standards. 192KHz is the best you'll get from Hitfilm Express, and it will be more than good Language, please.
In fact, Youtube's own recommendations page has the following about bitrate, " No bitrate limit required, though we offer recommended bit rates below for reference." While this phrase is specifically found in the discussion of video bitrate, it applies to audio as well. Recommendations are recommendations, not "rules." Youtube will cheerfully accept file that aren't the exact "recommended" format. Of course the exact content of your video matter immensely to the perceived visual quality at any given bitrate. That's the encoder YT uses for AVC results. If using the x264 encoder for upload then no worries. Tight when using the Mainconcept AVC/H.264 encoder than Hitfilm and other commercial editors so often use. This based on my own tests of Youtube results of extreme quality 1.2Gbps Cineform RGB uploads and Youtube recommended AVC/H.264 encode bitrate uploads and comparing bot results. Since a transcode always has some loss in quality I prefer the upload be some amount better than the YT final result. Tight as in too close the the Youtube final result quality. I would prefer a little more wiggle room. Speaking of video, IMO, the 8Mbps listed for 1080 <= 30p is maybe a bit tight for a lot of source material. Youtube cannot know what encoder you are using or what the content of your source material is and they throw out an extremely conservative bitrate for AAC since it will not affect the file upload size much since audio bitrates are so much smaller than video. Acoustically transparent is the term commonly thrown around. 192K is, or should be considered, as high bitrate for stereo with the AAC codec. It got some love and is pretty descent these days. Historically the libavcodec (aka ffmpeg) AAC encoder was not all that good.
I can't say what the quality level of the Windows OS AAC encoder (used by Express) or the Mainconcept AAC encoder (used by Hitfilm Pro) are relative to others. You cannot compare bitrate across AVC or HEVC or VP9. You can't just take bitrate and apply it everywhere.
If you think you can hear a difference between 192 and whatever higher then more power to you.
