hi all, ive tried using shotcut and kdenlive but the outputted file ends up being huge. i have a single image and want to put audio on top (releasing a song) but these programs end up making video files where they render the same image on each frame and the files end up being huge. what is the best way to achieve my use case of making a single photo music ‘video’ that doesnt degrade the quality of the image and can be posted to youtube?

tl;dr: need a still image video (image is lossless) where rhe imsge isnt reduplicared and has audio

    This might depend on where you’re uploading/how you’re playing this file, but you could add a thumbnail to the audio file? I know that vlc and mpv will play your audio file and show the thumbnail, but I’m not sure if YouTube would take that. Not sure if this is exactly what you’re looking for but it is pretty efficient.

    Are you sure your rendering settings are correct? It sounds like the video isn’t being encoded at all. Video encoding works by storing a frame in full quality every couple seconds or so. For the rest of the frames, only their differences from the previous full-quality frame are stored. But from what you describe, it sounds like the latter sentence isn’t happening

      oh i didnt think this is how it worked, i ended up using ffmpeg to make a one frame a second video but it still looks blurry??

    In kdenlive, the following settings work well for me (you can transfer the options to ffmpeg cli as well if you prefer that):

    f=matroska movflags=+faststart vcodec=libx264 tune=stillimage progressive=1 g=1000 bf=2 crf=%quality acodec=flac ar=48000

    For reference, I get a 3.7 GB video with a duration of over 5 h @4k resolution. The audio itself is already 3.7 GB and it’s just a still image. For CRF, set something around 23, that should do.

    Can you intentionally set various bitrate (VBR) with a big difference, like from 16mbps max to 1mbps min? Constant bitrate can be your problem. Premiere had this on media export menu, I can’t remember where others have this. And, if you want to upload it to youtube, see what size it has on a private upload by downloading it - they reencode every video themselves to their uniform standard, so maybe you don’t even need to bother with that.
