Waveform should have the options: audio toggle button; video toggle button

[Awesome Donkey]

IMO, that's a different thing completely than what's being discussed here and should be in its own topic.

[stan9980]

As the waveform is generated when audio analysis is performed, doesn't it make sense to have a toggle option for audio waveform and for video waveform with the other audio analysis checkboxes?

[Awesome Donkey]

Again, that's a different thing. As far as I know waveforms aren't calculated for video files at the moment, only audio files where it makes the most sense. So requesting waveforms for videos likely belongs in its own topic.

The overall general request of this thread applies to the audio analysis feature and the customization of what it tests for in audio files, not video files.

[Manfred]

Audio is part of video.

[pluto]

I support the Donkey's proposals

[Awesome Donkey]

Audio is part of video.

Sorry, in this context I disagree and requesting waveforms for videos files does not belong in this topic. This request and proposed solution above is for audio files only and is related to the audio analysis feature which currently exists, which as the name implies is only for audio files. There is no "video analysis" type of feature as far as I know.

In my opinion it makes no sense at all to calculate waveforms for video files even though you obviously disagree, hence why it's probably best to request a "video analysis" type of feature with support for the calculation of waveforms in another topic instead of hijacking this topic any further with that request. It's a completely different thing altogether than what's being requested here with customization of an existing feature for audio files, even though again you obviously disagree with that.

instead of hijacking this topic any further

I have not hijacked the topic.

That is not much of a problem but having to once again remove the unwanted data from the Waveform Tag is something most of us can do without; so can we please have creating the waveform optional. Something that JimH agreed was a good idea - see replies 10 & 11 in the "1. Changed: Waveform data is no longer being created for Video content thread" - https://yabb.jriver.com/interact/index.php/topic,128474.msg891651.html#msg891651

I believe you might've misread Jim's response in that thread.

I believe Jim was referring to the idea of the calculation of the waveform during audio analysis being optional, which is one of the main requests that the proposal I made above covers, and not per-say that it should apply to video files. I'm certainly not going to put words in his mouth of course, but that's the impression I got.

This thread is for the request, discussion and customization of not just the waveform but the other tags created as well by audio analysis for audio files only, not video files. My proposal above only covers audio analysis and audio files, not video files. Instead of taking the time to post replies here to the contrary you could've posted your request of waveforms for video files in its own separate topic where it should be. The request for waveforms for videos does not belong in this topic, and has nothing to do with the audio analysis feature and the proposed customization of said feature.

[Manfred]

I really disagree:

Please make waveform analysis for video at least an option.

Also the next post of this requires it

Waveform Analysis should be made OPTIONAL for EVERYBODY and not just for Video's!

and then JimH posted that it should be optional.

[stan9980]

When waveforms were calculated for video (as recently as 27.0.57), they were done so via the Analyse Audio menu. Hence my suggestion that checkboxes for waveform for audio and for video to be added to the list, so all the options are in one place. It was a genuine attempt to build on the discussion contained within the thread.

[Awesome Donkey]

Fair enough, even though audio analysis calculating waveforms for video files was unintended and a bug. Nonetheless any sort of "video analysis" used to calculate waveforms and other potential data for video files should be part of an overall video analysis feature with its own tags customization even though yes it's calculating the waveform for the audio track within a video. What should matter is the file type; audio files are handled by audio analysis and video files (even though they contain audio tracks) would handled by a video analysis type of feature.

However there's also complicated things to consider here, it's likely not as easy to do as you think... what if a video has multiple audio tracks? Does it generate waveforms for all of those? How does it or can it handle those with a single waveform tag? Or will it just calculate the waveform for the default audio track and none of the others? If it's considered, having a special waveform tag for video files (or multiple tags to handle multiple audio tracks within a video) might be needed, not sure.

Then there's the consideration that waveforms, especially when using theater view, could potentially be confusing to some users by needlessly complicating the seekbar. Having a waveform overlay at the top of the screen that could be toggled on and off or something like that would make sense, not so much having a waveform as the seekbar itself in theater view. I don't think very many people would be interested in such a feature to be perfectly honest.

I believe the only Audio Analyze option that is currently done for video files is the R128 functions. So, there is currently no need to have a checkbox for which analysis to do for video files. If you do not want to do the R128 analysis, just do not do Audio Analysis on video files.  If more functions are added to AA that do act on both audio and video files, then maybe separate checkboxes for audio and video files would become relevant. But, for now, checkboxes for video do not seem to serve any real function.

[mattkhan]

For me, the current implementation of waveform is useless but since the thread title is "a waveform for video files" then I'll suggest what would be a useful/interesting implementation of that feature (to me at least), namely a configurable (in terms of no seconds displayed on screen + channels shown) realtime waveform displayed as an overlay on the video, no offline analysis involved, just visualisation.

[stan9980]

One man's bug is another man's feature! I take the point about audio and video being different types, but under Options the video section deals solely with visual options and refers you to the Audio section for all the audio options so I don't see a problem with Audio Analysis handling the audio aspect of a video file given that precedent.

I hadn't considered multiple audio tracks, but what happens currently with Volume Leveling for a file with multiple tracks? I would assume the default audio track is used and that would seem to be a reasonable solution.

I don't use theater view, I can understand why it could be confusing but I find the waveform very useful in display view, as I've detailed before. However, making it optional surely solves this.

@dtc: I wasn't suggesting checkboxes for which analysis to do to video files, just checkboxes to enable waveform for audio and to enable waveform for video files, as had previously been discussed, in the mooted reworking of Analyse Audio.

Except waveform is not currently done for video files.  There is no reason to have the option unless waveform analysis is enabled for video files, which is a separate issue.  If waveform for video files is re-introduced, then an option makes sense.

[stan9980]

Currently, no they're not, but for a period from when waveforms were introduced, up to and including 27.0.57, they were. From memory, someone objected to the large amount of disk space the waveform file took up - I completely understand that. After stating my case for why I found it useful, there was agreement that it should be an option. A discussion about reworking Analyse Audio seemed like a relevant place to suggest the waveform checkboxes, as in the versions of MC that do generate waveforms for video it's done by using Analyse Audio.
