Re: Help with converting to AVI file using FFMpeg

./ffmpeg.exe -i <input-filename> -f avi -c:v rawvideo -pix_fmt bgr24 output.avi -f avi and -pix_fmt bgr24 aren't needed. If you only want to compare the videotrack, then you can add -an to exclude the audiotrack (from being converted to mp3): ffmpeg -i "AVI(Uncompressed)-SD.avi" -c:v rawvideo -an o...

Re: Video bit depth

I'm a bit confused by the zscale filter suggestion. It does resolution- , range- and colormatrix-conversions, but it doesn't change the pixel-format as far as I know. Aorangi, I have no idea what "Davinci resolve" is, but if you want to convert your video to 4:2:0 8-bit, then... ffmpeg -i <input> -p...

ffmpeg -i input.avi -acodec mp3 out.avi
'out.avi' should in this case be created in the same map as 'input.avi'.
I suggest you search the internet on how to use command-line programs.

Re: multiply audio pcm to 5.1

Can you please be more accurate in describing your current situation and what you want?!
It is unclear to me whether you either have 1 wav-file with 16 channels that you want save as 16 separate ones, or 16 separate wav-files that you want to merge to 1 wav-file.

Re: Speed Up Video

I need to get 60 fps and the input video is 50 fps. So, 50/60 is 0.8333. Well, that's very confusing, because in your first post you said: "I want to speed up a video sequence from 30 fps to 60 fps " . Please make up your mind. In that case 11.13s * 5 / 6 = 9.275s is exactly what you get with setpt...

Re: Speed Up Video

The outfile.avi number of frames is 555 and the duration is 9.25 sec. I'm not sure why this is happening. It's the result of setpts=0.833*PTS. I don't understand how you came up with 0.833. ffmpeg -i input.avi -lavfi setpts=0.5*PTS -r 60 -c:v rawvideo output.avi This should do the trick. Also see H...

Re: Windows XP compatible non-SSE2 FFmpeg builds

- Renamed all new releases in a more recognizable way, including a version and build string for FFmpeg. So, there's no difference. Just a new way of naming the archives. To be more precise, 4.3-dev-327-g83e0b71 is the output of git describe --tags | tail -c +2 . If I would've continued the old nami...

Re: Standard pal tag with 1920x1080

I could be wrong, but afaik is PAL a standard from before the High Definition era. So no, it doesn't make sense and is impossible if you ask me.

All I want to do is change my container from MOV to MP4 without any quality loss

Code: Select all

ffmpeg -i input.mov -c copy output.mp4
I don't understand what the irrelevant "input.avi" and "output.mkv" have anything to do with this.

Re: Error running command: could not get mpeg2 profile and level av_interleaved_write_frame(): Operation not permitted

There's nothing wrong with the mapping. Your suggested -map 1:1 doesn't even exist.

APerson has also posted this on SO and according to "llogan" this is probably a bug.
