Aresby Posted December 28, 2016 Share Posted December 28, 2016 I don't understand this: I've created a short 30 second video which consists of some text and audio narration (created by recording my voice within VP). Sounds fine in VP but when I export it (with exactly the same settings as I always have done) it sounds distorted as though it's clipping (even if I speak really, really quietly). If I record a video using OBS and import that and then export it (as above) it's fine. But narrated audio in VP always sounds awful even though it plays fine within VP. Using version 4.58 in Windows.I've used the Record > Narrate often and it's always been fine up until now. Using 128kbps quality, 25fps for the video, 8192 bit rate (as always for YouTube). Anybody got any ideas? (I guess it will only take you a minute to try and duplicate this). Link to comment Share on other sites More sharing options...
borate Posted December 28, 2016 Share Posted December 28, 2016 Where are you setting the "quality" options? Have you checked the mic level input at the Windows mixer? Right-click the speaker icon (in the notification area) and click on recording devices. Tested a narrated export (mp4) here and results matched those in VP preview.

Aresby Posted December 29, 2016 Author Share Posted December 29, 2016 "Tested a narrated export (mp4) here and results matched those in VP preview." In that case I will have to experiment further, perhaps it's a 4.58 change. Remember that I do this sort of thing several times a week (narrate, that is) and this is the only time I've had a problem. I will follow your guidance and if no luck send you the project (only 30 seconds long) with my generated output to see if you can repeat it or tell me what's going on!

Aresby Posted December 30, 2016 Author Share Posted December 30, 2016 Please sent the files to me. I've uploaded the VP project (EndCardsTestNarration) and narration (.wav) files, plus the generated .mp4 output to this location: https://www.dropbox.com/sh/4owslf2e9g0tamh/AACi3ik8zF_u3RyJvpVMyQ1aa?dl=0 The audio when playing in VP sounds as I would expect; the generated audio in the .mp4 file sounds clipped. This only happens when using a narrated source, not a video input file, I've found. I'm generating the output at 25fps YouTube HD 1920 x 1080, custom quality of 8192 bps and audio at 128k (these settings have been used for the past 12 months). Can you hear the distortion in my generated .mp4 file? Does your generated .mp4 file sound the same? I've double-checked all the microphone input level settings. Remember that I'm still recording video using the same audio settings using OBS and everything is as it always was, just fine. Link to comment Share on other sites More sharing options...
borate Posted December 30, 2016 Share Posted December 30, 2016 4.58. The audio level of narration was low, so the original track was replaced with a normalized copy. Outputted two video files, one using the MPEG4 compressor with 8192 avg. and max. settings, 128 bit rate, 25fps YouTube HD 1920 x 1080...and the other using the H264 encoder defaults. Both sounded identical, with no clipping. Here's the H264 final. Try using default audio settings. Link to comment Share on other sites More sharing options...

Hi Aresby, as borate said, it seems your output mp4 file has been normalized. Can you please check your videopad->Options->Media and make sure "Automatically normalize audio volume" is disabled.

Aresby Posted January 20, 2017 Author Share Posted January 20, 2017 Just saw the above response about my narrated audio - I'll certainly try this but I do really want the audio on the entire video normalised (when exporting and during playback in VP), so by disabling it will this cause me issues? BTW I'm not even sure if I've got that setting checked, I'll test it out on Saturday (21st Jan). Link to comment Share on other sites More sharing options...
Nationalsolo Posted January 20, 2017 Share Posted January 20, 2017 Hi For what it may be worth.... Yes, the sound on the utube clip is clipped. I have just done a short test with a couple of clips to see what I get as narration with previous versions of VP have been OK.. These are the stting I have used...... In Audio Options....Normalized audio volume is ticked. I am using a small mike plugged into the "Microphone" socket (Pink) on the front panel of the PC I have muted the existing sound on the clips so as to hear the narration result better. Select Audio...Record...Narrate Settings:- (Default Sound In) Windows Record Mixer I have a Realtek microphone option but have selected the default option. Click red button and record the narration. The played back file sounds perfectly clear. (Microphone about 3" away) The recording level meter stayed in the yellow zone throughout. The played back video in VP sounded perfectly clear. Exported the video as a Video File (To PC) Preset to Custom File type .mp4 Resolution 1280 x 720 U tube 720 Encoder options: Compressor H264 Quality 10 (High) Audio average bitrate 320 The exported videoclip played back perfectly clearly without any clipping. The microphone level was set up via the control panel. Nat Link to comment Share on other sites More sharing options...
Aresby Posted January 22, 2017 Author Share Posted January 22, 2017 I tested this out, using the settings suggested by Nat et al and discovered a few things. 1. I set Normalise Audio on (a full description of how things works - you say it replaces existing audio rather than just amplifying it? - would be useful) as I want my entire video at a fairly standard audio level when exporting (a bit like how a radio station might do it, with both compression and limiting). 2. I discovered my input audio source was set to the USB microphone so I changed it to Default Device and Windows Mixer and found that the USB microphone was already the default device but it was set at 78% input level. 3. I discovered that I had OBS set to a 10 point amplification setting because the microphone level was a bit low. 4. Setting the microphone level in Windows Mixer to 95% (I found 100% made it go to max too often during general speaking) and removing the OBS amplification factor I found that: Narration in VP sounded just fine during playback and after video export (no discernable clipping on final mp4 video) OBS did not object to the new 95% microphone level when recording raw material and indeed, went to about 95% of 0dB during recording The OBS video sounded fine (a little louder than usual but no clipping) On importing video into VP it sounded fine with no clipping, although the waveform indicated a higher than usual level On exporting from VP into final mp4 it sound just like VP playback, no clipping So it seems that thanks to your great suggestions I have cracked it! Not only that, I've got "better" settings because the audio going into OBS is higher requiring no boost, and the resultant video into VP seems to be handled just fine too, and I might be able to speak slightly further away from the microphone to allow a greater dynamic range (but not too great). Thanks guys, let's hope it stays this way! (But an explanation of how Normalise Audio works would still be useful) Link to comment Share on other sites More sharing options...
borate Posted January 22, 2017 Share Posted January 22, 2017 Some OBS info, if you haven't already run across it. Extract from Wavepad HELP... To 'normalize' is to adjust the volume so that the loudest peak is equal to (or a percentage of) the maximum signal that can be used in digital audio. Usually you normalize files to 100% as the last stage in production to make it the loudest possible without distortion. Another reason to normalize is to have multiple tracks sound equally loud, or to have equal average loudness. Link to comment Share on other sites More sharing options...
Rhea Posted June 30, 2020 Share Posted June 30, 2020 A whole bunch of years later I'm experiencing the same problem. No matter how I export the video, spoken word is clipped and disgusting, barely understandable. Mind you this is audio track linked to the video, recorded with GoPro h265. Original audio quality, and the preview playback are both perfectly fine, the issues is just with exported video and this started to happen with the update to version 7.32 and "Automatically normalize audio volume" in the Settings/Media is disabled. I tried exporting it with default settings and also with the highest bitrate on both h264 and mpeg4, nothing changed. (Note that exporting to h265 doesn't work at all.)

borate Posted June 30, 2020 Share Posted June 30, 2020 Best to begin a new descriptive topic. You mention that this began with 7.32. What version is being used now? Try this For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info. If the issue persists, please upload the PORTALBE project (not the export). Someone will check it out. This is easy, quick and can be private. http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/ If it contains sensitive material link it in a personal message (PM).
