Dj mix with same still picture all way long for Youtube

[Ysl]

Hi

Please help me with the settings ! I drop a DJ mix (xxx.mp3 150 MB with artwork - 1 hour) with a still picture into Shotcut, select ‘Youtube’ and export the video but it save me a 7 GB .mp4 file (with a distorded/saturated sound with PotPlayer - OK in VLC)…!

How to conserve the original mp3 sound (no re encoding if possible) and only add the still picture for a rapid encoding and light file size.

Thank you for your help

OK I have a ~90 Meg MP3, and a 22kb PNG file. The audio plays for 8 hours 30 mins. OK to me, 90 Meg plus almost nothing = 90 + a little more. But I understand this is reconfigured from a single image into 3 nearly 3 hour images (I worked this out) and into jullions of frames per second etc… When I export it as a standard definition NTSC file, which seems to play on everything and every website will play it…but the file is around 900 Meg. This is just too huge. Even the old lost file I extra…

Writing MP3 audio into an MP4 container with ffmpeg creates a file that is not playable with some media players. For highest quality audio, change the audio format to lossless (ALAC for MP4) which would be as good as no re-encoding. Otherwise, choose AAC or AC-3 for compressed audio.

Thanks but if I choose Alac or Flac I get an ‘aborded’ message when I try to export…

I still wonder then what are the settings to get the ‘video’ with a still image and a mp3 file with a reasonable file size…
Here is what I try to achieve (was done with a web service which no longer exist) : https://www.youtube.com/watch?v=sioI4NfF_o0&t=2851s

Don’t use the Youtube preset, it has a GOP size of 15, use “default”. which has a GOP size of 300.

I just did a test exporting a video with just a PNG. The quality of the default is the same as the Youtube video, the “default” filesize is 6x smaller (Youtube 177MB, Default 28MB).

Thanks, I tried ‘default’ and indeed I have a .mp4 file with reasonable size BUT I have no image !
In my original .mp3 file there is an artwork embedded which I see in Shotcut but it doesn’t appear in the video… Can I put manually the artwork .jpg in Shotcut somewhere ?

Can I put manually the artwork .jpg in Shotcut somewhere

Yes

JPG and PNG images can be in your playlist just like a video clip or an audio clip can be.

Ok but please help me by telling what I have to do and how to do it…

I drag/drop a mp3 file without artwork then drag/drop the cover art in .jpg, select ‘default’ and then ‘export’ and shotcut crate me a file of 3KB with nothing in it…

Do you have “Use Hardware Encoder” selected for the export. If so, de-select it and export again.

Can you show us a screenshot of your project in Shotcut?
Do you add audio to an audio track (A1) and then add an image to a video track (V1)?

A simple video to show how to do it:
