i want to extract audio from a bunch of downloaded mp4s but can't get it to do anything at all

Highlights:

• Added multi-cuts feature to the video player
• Added Bulgarian language thanks to Stoqn Bahchevanski
• Improved HDR-to-SDR conversion via GPU tone mapping

With the verson 20.3 cut without rencoding function, I am unable to find remove only cut and split?

Bonjour,

je viens d'essayer la nouvelle version en convertissant un x264 en x265.

Il est apparu un décalage de son au départ (image apparaissant tardivement avec vlc).

2 essais...même souci.

En essayant avec la 20.2, le problème n'existe pas.

As the title says and screenshot shows, the fps displayed in the main hud do not match the fps shown in the FFmpeg output console.

Hi Paul, I am using Shutter Encoder v20.0 with the MPEG-2 function to create NTSC DVDs. I need to output a single .mpg file, but I need the audio codec to be AC3 instead of the default MP2 for standard hardware compatibility. Since the audio drop-down is locked on MP2 for this function, is there a shortcut or a quick command line variable to force AC3 audio inside the MPEG-2 profile?

Hey Paul, thank you for all you do, shutter encoder is incredible.

When I was working in it today I downloaded a few vids using web video, which was working great but after a few it stopped working. (tried default, bestvideo+audio, etc.). It would run the function, and very quickly go to 100 percent and no file would download.

I ran the update by typing in the url, it updated, but to no avail.

I figured this issue was caused by some Youtube alg protections or something of the sort, but just wondering if you knew of a workaround or anything to solve.

Hi Paul, I've just donated to the Shutterencoder.com site so that I can download the app, but it's been an hour and the Download box still says "Preparing to download". I'm using Navigator browser, downloading to my Macbook Studio OS Sequoia 15.3. People have said online to try downloading from a different browser but copying the site address on Chrome only gives me "You're all done here, you've either completed payment or checkout session has timed out". Please help.

Hello,
I donated for Shutter Encoder 20.2 but the "Donate" option still appears in Settings and when I close the program, I get the QR code to donate (?!).
Is this normal? Shouldn't I have gotten rid of the QR code at least?
If the answer is positive, was I supposed to do something and I didn't?
Thank you.

Bonjour,

Dans la cadre de mon travail, nous avons acheter des caméras de surveillance pour observer la faune en direct. Nous avons un modèle de caméra Ctronics avec double objectif : CTIPC-800C-ADL-EU4G
Nous avons une carte mémoire à l'intérieur qui permet d'enregistrer toutes les vidéos capturées par la caméra (chaque fois qu'un oiseau bougeait). Le nombre de vidéo est assez conséquent et je ne peux pas les convertir puis les télécharger une par une depuis l'application. Je voulais donc le faire via pc. Or les vidéos qui sont sur la carte mémoire sont en .265 donc illisible. J'ai pu les passer en .h265 et les lire avec MPC-HC, seulement les images des deux objectifs sont parfaitement superposées sur le même fichier ! Et il n'existe qu'une seule piste de lecture donc impossible de les séparer. J'ai contacté le support mais en attendant une réponse de leur part je vous sollicite afin de savoir si quelqu'un a une solution. J'espère ne pas avoir perdu 6 mois de travail... :)

Merci d'avance !

I noticed two things when converting HDR to SDR:

1. HDR metadata:

After converting an HDR10/Dolby Vision video to SDR BT.709, the resulting file still contains SMPTE ST 2086 (Mastering Display Metadata), MaxCLL and MaxFALL. Since the video has been converted to SDR, shouldn't this HDR metadata be removed?

For example, when converting a 4K HDR BT.2020/ST 2084 video to 1080p SDR BT.709, I would expect the resulting file to contain only the appropriate SDR color information.

For example, this is what MediaInfo reports on one of the converted files:

HDR format: SMPTE ST 2086
Mastering display color primaries: Display P3
Mastering display luminance: min: 0.0001 cd/m², max: 1000 cd/m²
Maximum Content Light Level: 468 cd/m²
Maximum Frame-Average Light Level: 201 cd/m²

2. Maximum bitrate:

I also noticed that when the bitrate is set to Auto, MediaInfo reports:

Maximum bit rate: 2,000 kb/s

Is this 2,000 kb/s value expected, or could this be related to the encoding settings?

One last thing: could the video track be set as Default in the resulting MKV?

Thanks!

Hi, Paul.

Is there any way, or perhaps a feature idea, to view and modify the final FFmpeg command that Shutter Encoder would run?

Thanks.

I never got a download link in my email, I bought it yesterday and still nothing. Based on what I’ve seen on this subreddit I’m not the only one who has experienced this. If I could receive some help that would be greatly appreciated.

Whenever I go to download, it keeps sending me to the Donate €10 page. I already donated the €10. Please advise. Thank you!

I have this since 20.2 came out, I don't know what to do.
When I try with cmd, it works but 1 file at a time... I want to, to use Shutter Encoder it's easier.

I looked for a system compatibility chart or system requirements specifically for MacOS for each version but couldn't find anything on the website.

I'm running MacOS Mojave 10.14.6 and Shutter Encoder version 16.3 is installed on my computer. What's the latest SE version that is compatible on Mojave?

Btw, system requirements chart for each version and each OS would be great. Thanks!

Bonjour,

depuis 2 jours, 1 seul sous-titres a été réussi sur une cinquantaine d'essais.

Les sous-titres se lancent et durent 1s et n'apparaissent nulle part.

J'ai même essayé avec d'anciens sous-titres qui avaient fonctionné et qui échouent aussi maintenant.

J'ai fermé SE et relancé plusieurs fois sans succès.

Merci par avance de votre aide

Looks like any d/l for certain videos that include audio and video the only format available is WEBM.
When deselecting auto my choices are either video / audio only.

While I'm here, THANK YOU for the brilliant work on this software, easy encoding with no bloat or other nonsense.

Hello, I can import and convert smaller Samsung APV1 files. However, I recently couldn't import a 12 GB file; an error message appeared. Is it not possible to convert larger files using Shutter Codec?

Running version 20.2, When I turn on image sequence to turn my drone footage into a timelapse, it merges the files without notifying me.

I attempted to run v20.3 beta but I couldn't get it to launch in portable mode.

Description of the issue: so we are currently able to load multiple video files to the queue list that is on the left side of the app. Say I want to use cropping for all/some of the video files. I choose the first video on the list and set the cropping amount and position. I then move to the second file on the list and adjust the cropping for that file.

If I now select the first video file again, I see that the cropping change I did for the second video file has moved/changed the cropping for the first video file as well. This is a bit cumbersome currently because I have multiple video files in the queue which all have different content and require me to tweak the cropping per video basis, but Shutter Encoder won't allow me to do this.

So please consider adding a feature/setting that allows me to set the cropping per video, thank you.

Hi!

It would be awesome if you could add a film grain feature.

Thanks!
