You forgot to specify the input pixel format.
Many parameters are missing for the raw output. But the error message is
from the input.

Do you really want raw video? That's not the easiest format for a beginner.
Everything must be specified for the input (file format, pixel format,
size, framerate, and whatever I may have forgotten...) and the same
things must be specified for the output again.

[image: image.png]
this error pops up when I add the flag -f rawvideo (I have a raw files,
should this be used for raw video?)


I tried by giving the input with -pix_fmt, it's the same error.

Yes, I want raw video. I have converted RAW files to .mp4 successfully with
uncompressed, the size of the .mp4 format video was less comparatively.
I have 30 RAW files with each file is around 4Mbps (so, 30 RAW
filesx4Mbps=180Mbps for one second), the output of the video file size
(.mp4) is coming around 18 Mbps, so I am assuming .mp4 video format is
doing some compression and hence I need to try this with RAW video.


What do you want to do with the RAW video? You know that you can't play 
it with most players?

This is the command I tried for .mp4 file video which is coming 18Mbps as
output video file size,
*ffmpeg -pixel_format gray10le -s 1600x1300 -r 30 -i CapturedImage-%03d.raw
-c:v libx264 -pix_fmt yuv420p -preset fast -profile:v main -level:v 4.0
-crf 1 raw_video.mp4*

Please show us the command output of making an mp4 file.

the

RAW Image file is,

Do not specify a video codec, or set -c:v rawhide, set your frame rate /
resolution / bit depth params and use .raw as extension.

I tried as you suggested, I get the below error,

You must specify all relevant parameters for the output file at the
correct place in the command line. After the input file name, and before
the output file name. I think you must also add -f rawvideo
Remove -crf 1, as it makes no sense for a raw file.

avoid special chars in filenames or escape them properly and in general 
use quotes - PEBCAK (problem exists between chair and keyboard)


https://ss64.com/nt/syntax-esc.html

Escaping Percents

The % character has a special meaning for command line parameters 
and FOR parameters.

To treat a percent as a regular character, double it:

%%

Many characters such as \ = ( ) do not need to be escaped when they 
are used within a "quoted string" typically these are characters you 
might find in a filename/path. The percent character is one exception to 
this rule, even though under NTFS % is a valid filename character.

[FFmpeg-user] Convert from TIF to DNG

2022-10-24 Thread Michael Koch
On a website (1) I found the idea that a TIF file can be converted to a 
DNG file just by adding some tags and renaming it. Let's test it. Make a 
16-bit TIF file:


ffmpeg -f lavfi -i nullsrc=s=320x320,format=yuv444p10le -vf 
geq=lum='X/W*32+32*floor(Y/H*32)':cr=512:cb=512,format=rgb48be -frames 1 
-y test16.tif


Add some tags:

exiftool -DNGVersion="1.4.0.0" -PhotometricInterpretation="Linear Raw" 
test16.tif


Rename the file to DNG:

copy test16.tif test16.dng

The DNG file can be opened with FFmpeg without any problems. But all 
other programs complain that the file is corrupt. I tested with 
IrfanView, FastStone, Gimp and Fitswork.

What else might be required to make it a valid DNG file?

Michael

2022-10-24 Thread Naveen.B
Hello Team,

I need to encode to a RAW video instead, could you please let me know the
command for this?

RAW Image file is,

fps-30
bit depth-16bit

Thanks and Regards,
Naveen B.
