Aika ...DVAJ-604. An uncorrected Whisper translation. Little over 1000 lines, but gets the message across.

I use a movavi suite in it a file converter is included with the program that it includes it also has the option to upload the audio of the file when converting to an audio file (m4a) it even has the option to eliminate noise and also the option to equalize the audio of voice (that the loudest audio of voices are equal).
I use Quicktime to convert, into m4a. I think it's better than using mp3. Although I think it takes a little while...But m4a is more precise imo. Also do you know if is there any free alternative to movavi for mac?

""Danger, Danger ... Will Robinson! (In case any of you remember "Lost-in-Space"!) I have been trying to use Whisper to Translate TOEN-049. For the first time the srt timing is off, even after correcting for the beginning of the video, it slips again a couple of times! Arrrg! It seems my copies of TOEN-049 from supposedly from differt sites all contain the same hiccup between the video stream and the audio. Anyway, I'm trying to correct and edit my subtitle (probably for my own use, because I kinda like the movie). Just wondering if anyone else has encountered similar problems. I don't think it's the fault of Whisper BTW.

It's strange because the video players I have seem to sync back up and their audio and video will continue to match. But if you look carefully you can see the video fuzz out at several places in the video and then snap back. Apparently this is something that Whisper doesn't like?

Aika PRED-405. I'm not usually into the 'drugging the girl' (pheremones) videos, but some of the scenes were really good. Another Whisper sub. I tried three different levels of VAD thresholds, and the higher I got the more unique lines were found. However, way more time errors and repeats. I just tested out a PIYO video and got 3600 lines, but with only 200 or so repeats. Still better than any other methods I've used and I'm happy even with only 500 or so lines here. Enjoy!

Can I ask which VAD thresholds you tried? It defaults to .4. Was wondering how high to raise or lower it.

All 1080p has corrupted audio, you should download 4K version that's not corrupted.

Hi - may I know the logical explanation on why m4a is better than mp3? So that I will also use m4a in the future.

It's a more modern audio compression format(m4a is aac) than mp3 and it's better at compressing than mp3 is. But opus beats both since it's even more modern and compresses even better so if you're going to convert it, which I wouldn't unless you're modifying the audio in some way, then better use that instead.
Whisper is going to read the original audio just fine so just demux(extract) it instead, zero quality loss this way.

There is an existing sub for TOEN-049. Check it out if this does the job:

Thanks but I think I have corrupted copies of the movie as this subtitle file acts the same way about 57 mins into the movie the subtitle and the video are out of sync. I have had difficulty locating another copy of the movie to use but will keep trying.

Thanks again.

I used .5, .6, and .8. The .8 had the most lines, but was off by up to 30-seconds timewise. It wasn't a good test movie as there was a lot of mumbling. I'm going to try something else a little clearer.

That's odd. I just tried processing a file at .6 then .2, and the .2 gave more lines. One would think if it is a detection threshold for audio, the lower number would catch more.

The problem with comparing setting is that whisper isn't reliable. Even using the exact same settings, you'll get a different number of lines every time(never tested the same audio more than 4 times though but that's a lot already).

No idea how it can sometimes fail and sometimes not with the same everything but it does.

Wow, that is extremely strange. If the code remains the same, it should return the same result with the same input every time.

Beginning to wonder if I should just try re-running those that didn't turn out well and see if they randomly get better.

May i know the average size of an audio that is extracted from 1-hour video? Because when i am converting a 1-hour video to mp3 it has an average size of 120mb. I wonder what is the size of an extracted audio compared to mp3. Thank you for your explanation btw. :)

Depends entirely on the bitrate used to encode the original audio. What matters most is the quality of the audio. With equal size, between mp3, m4a(aac) and opus, opus will sound closer to the original, followed by aac, followed by mp3.
And if you encode the original audio to either of those 3 format, you're going to lose some quality which could affect the ability of whisper to recognize voice(but in practice it doesn't seem to have much effect, although it's hard to tell with the randomness of it).
That's why I recommend keeping the audio as-is and just separating it from the video, you get the best possible quality this way and as a bonus, the size is usually smaller than if you use quality settings for mp3s.

To answer your question more directly, these days, I see either 192Kbps aac audio in most HD releases which would be about 87MB per hour if I did my math right or 128Kbps which would be 54MB and also the most common bitrates you'll encounter for any audio from ripped movies.
Sounds like you're using 256Kbps for your mp3s which would be around 115MB with the same math which is bigger than most audio I've seen, it rarely goes above 192Kbps(for ripped content, DVD/BluRay audio is much bigger).
I use 128Kbps opus for my own encodes for the quality version(which is of similar quality than your mp3 but only half the size) and 64Kbps for the small version.

About Whisper. Does Whisper Collab really accept other formats than mp3? It's the format that is written on the audio_path: line and I can't find any info on audio formats that can be used in the help.

I used mp3 in the beginning, changed to mp4 and now wav. Whatever input you give, it converts it to wav mono.
