But you can also customize parameters like duration, resolution, and more if you want to have more comprehensive control over the exported MP4 file. You can convert JPG to MP4 within just two steps with VideoProc Vlogger: import and export. Compared with tools of all kinds, VideoProc Vlogger could be one of the best choices to convert JPG to MP4 on Windows and Mac without losing quality. Convert JPG to MP4 Windows 10/11 & MacĪlmost any video editing software will convert JPG to MP4. Keep reading to find the best solution for you. Here we list three simple and free methods to convert JPG to MP4. So whether you only want to convert one single JPG to MP4 for uploading to video sites, or you need to combine hundreds of JPG files to create one MP4 file, it's all possible. And MP4 is the most popular container format for video and audio, as well as subtitles and images. We all know that JPG, or JPEG, is a format commonly used for lossy compressed images. I suspect that it is actually the audio in your case consuming a large part.I saw people asking how to convert JPG to MP4 on Reddit and Quora. In a nutshell, you may need to tweak these parameters a little bit in order to improve things. This produces a 100 kbit Audio stream which was more than OK for my sample. The quality of the jpeg was very low but got better when I increased bufsize. I lowered the values until I got VBV underflow messages then raised it back again. This has a direct impact on the video bitrate. Here is what the parameters do and how to use them: I have tried ffmpeg -loop 1 -y -i image.jpg -i audio.ogg -shortest -acodec mp3 -qscale:a 7 -vcodec libx264 -preset ultrafast -tune stillimage -maxrate 5K -bufsize 100K -crf 25 -pix_fmt yuv420p -g 100000 result5.mp4Īnd got a video file that was half the size of the ogg file. There are a couple of things which you may still tune in the x264 encoder like listed here but also in the mp3 decoder like shown here if you are OK with a lower audio bitrate.My assumption is that not everything is eaten up by the video. ![]() So something is very wrong with these codecs or the way they are parameterized. If I just put a new full key i-frame copy of it every minute, then I'd get 10 MB for the "video" payload, not 60 MB. What I am not OK is the video encoding or something else giving this codec license to stream data out in ~200 kb/s, kilo-bit, even if that is at 4x the speed, 50 kb/s is still too much if the payload goes with less than 1 kb/s.īTW, that Title image JPEG is 170 kB in size. Imagine what a 300 bits per second teletype terminal feels as you type! And now imagine how you can talk faster through this sort of low bandwidth line than you can type and see a screen refresh!īut I'm perfectly OK with the MP3 audio perhaps being a little bigger. That is 303 bits per second! That's pretty awesome encoding power of this one channel mono ogg audio. Here is some more calculation to show just why anything above 20 MB should not be acceptable.Īudio in the ogg compression is 8.61 MB in size. How can I make the most compact mostly-audio + still image video that youtube will actually finish processing? ![]() I read about the -g option: ffmpeg -loop 1 -y -i image.jpg -i audio.ogg -shortest -acodec mp3 -vcodec libx264 -crf 25 -pix_fmt yuv420p -g 100000 result.mp4 So I thought if I could have only one i-frame and the rest p-frames which should be basically empty because the "video" has no changes to the picture over time. That creates a huge file of over 120 MB in size! I have crappy internet, not going to blow a 120 MB just to upload it you youtube. ffmpeg -loop 1 -y -i image.jpg -i audio.ogg -shortest -acodec mp3 -vcodec libx264 -crf 25 -pix_fmt yuv420p result.mp4 Ideally I would just use the awesome ogg compression passing it through: ffmpeg -loop 1 -y -i image.jpg -i audio.ogg -shortest -acodec copy -vcodec libx264 -crf 25 -pix_fmt yuv420p result.mp4īut that doesn't play in some players, so I won't even bother youtube with it. First I just used VLC and output a youtube SF or whatever output, but YouTube churns on that "processing 0%" for days on end now. So I made a JPEG cover picture of 1024 x 768 pixels. ![]() I want to upload it to YouTube, so I have to make it at least a single-frame video. I have a WhatsApp message of 1 hour duration, it is an.
