If you are new to this tool, here are some handy commands that will give you a better idea about the capabilities of this powerful tool. ffmpeg -formats command to list all supported formats. 15 FFMPEG Command Examples in Linuxįor more details about FFmpeg and steps to install it in different Linux distros, read the article from the link below:įFmpeg Multimedia Framework Installation Guide on Linux – Part 1 Useful FFmpeg CommandsįFmpeg utility supports almost all major audio and video formats, if you want to check the ffmpeg supported available formats you can use.

Could anyone modify my code to provide better encoding at the beginning of the file?įor reference, the original 10mbps mp4s are encoded by Premiere 5.0 and do not have blockiness at the beginning. How can I tell ffmpeg to pay more attention to the beginning of the video? Do I have to resort to 2-pass encoding? I don't want to nearly double the render time because only the first few seconds of the video have this problem. Slowing down the rendering time by changing the preset to "veryslow" only marginally improves the first few seconds, but it increases render time dramatically. Then, after about 3-5 seconds, the stream "corrects" itself and the video is crisp and clear. The problem is that in the first few seconds of the video, the stream is very blocky.
These settings work wonderful and after lots of tweaking to get this code, it produces crisp, clear video for high action, stills, many different colors, etc. profile:v main -preset slow -b:v 400k -r 30 -c:a libvo_aacenc -b:a 128k -s 1280x720 -movflags faststart -f mp4 "test-done.mp4" I am using the following code to transcode a 10mbps high quality 1280x720 H264 mp4 into a lower quality H264 mp4 with our logo watermarked on the video.įfmpeg.exe -i test.mp4 -i watermark.png -filter_complex
