Problems using ffmpeg

[StudentMZ]

Hello everybody,
i just startet at the university and now i'm working on a project using ffmpeg to convert different picture formats.
now i have two questions:
1.
The workflow is converting an image series of 580 pictures to YUV
after that using the TApp Encoder
and later on reconverting the YUV to the native picture format......


while using DPX i had no problems and everything worked fine....
Now i tried to use TIFF and i had a lot of trouble:
using 16bit TIFF - i get a lot of block artefacts after converting
usn 8 bit TIFF ffmpeg converts the pictures into YUV, but doesn't convert them back to TIFF - I get an error message

the workflow was the same like using DPX files......


2.
what does p10le mean?! using 420p10le as picture_format

( sorry for the bad language )

1) Post your command lines and error messages
2) 420p10le means 10bit depth, 420 chroma subsampling, little endian. The "p" means planar

hello
thanks for answering #2
that helped alot but brought another question.....
if 10 stands for the bit depth... do i have to use 8 if i have 8 bit pictures or is the 10 bit only for the codec?


1)
call ffmpeg -s 1920x1080 -pix_fmt yuv420p10le -i C:\Users\HDR\Desktop\YUV-Dateien\vorFH\innengut_5mbps_rec.yuv -pix_fmt rgb24 -y E:\NeuDPXFiles\innengut5mbps\innengut_5mbps_rec_%0 3d.tif

I think TIF only supports 8 and 16 bit depths - at least those are the most commonly used

If your source is 8bit YUV (and originally 8bit RGB), you should probably use 8bit because your destination is 8bit RGB - unless you are testing 10bit compression formats specifically

You're going to incur some losses converting between YUV and RGB



I don't know about the block artifacts, can you post some samples, or provide more details ? Or perhaps they are intrinsic to the settings you used for TApp encoder ? Do they occur on every frame ? What sorts of bitrates were you using ?

here is the file from TAppEncoder:

these are my codes:

call ffmpeg -start_number 00090000 -i E:\TIFFDateien\Einzelbilder\Aussengut8bit\vorFH.%8 d.tif -pix_fmt yuv420p10le -y E:\TIFFDateien\Einzelbilder\Aussengut8bit.yuv

[StudentMZ]

I did the workflow again but instead auf using -pix_fmt yuv420p10le i wrote -pix_fmt yuv420p and everything went fine......

as you already explained that 420p10le means 10bit depth, 420 chroma subsampling, little endian, which bit depth is it using without the 10le ?!

[Selur]

which bit depth is it using without the 10le ?!

8bit

[StudentMZ]

ok thank you !

is there a way or combination with which i can encode/decode 12 bit DPX or TIFF ?!

Not as 12bit

HM software: Encoder Version [10.0rc1][Windows][VS 1700][64 bit]

You should update your HM software, that build is outdated. I think it's up to version 13 now . Perhaps the issues are with your encoded and/or decoding
