ac-chan123: thank you for the idea, I've actually used that workaround in the past but I have several huge sequences to process that way and it is not just possible to do it like that this time. I'm currently looking at the rawsource code to see how that could be done, but i've never coded avisynth plugins
before so that could take some time.

I've actually done it
It's a quick and dirty mod but it seems to work.
I've tested it succesfully on very long raw UYVY sequences and it should also work on any other format with no headers (I actually ran into problems so I got rid of the header part as I don't work with these kind of files).
NB: it is ONLY for file sequences (1file=1frame).
If someone is interested I'll post the sources somewhere.

RawsourceSeq

Here we go, I've called it RawsourceSeq, manual is included, it has only been tested by me on UYVY sequences so expect some bugs to occur
(all credits go to Warpentreprise, I've just modified Rawsource)

I'm a little bit sorry that I come too late, but I had some other code fragments lying around - so here is my version, too. It is built into imagesequence (as yours it does not use files with header, this makes no sense anyway for single pictures).

I'm trying to import some YUV archive sequences using RawSequence (in ImageSequence),

http://www.ldv.ei.tum.de/page70

The 1080p25 series load OK as the files are straight .yuv and pixel type I420. However, the image files of first three series (576i25, 720p 50/59.94 and 1080i 25/29.97) are in .qnt format and I just cant get then to load.

There are some image converson softs out there that support qnt files but they are either for Macs or costly professional programs (with no demo available).

I'm also having the same problem with some archives in SGI format, which I understand is an 16-Bit RGB variant.

Any idea how I can get these images into a format that ImageSequence will accept?

Cheers.

Edit:

I know DRMPEG has the sequences compiled as HD-MPEG2 transport streams on his webpage

http://www.w6rz.net/

but I would like to output the original image sequences as (FFDShow)HuffYuv-YV12 to serve as reference masters.

I've also found a tool that converts SGI to YUV, but its a command line utility and I havent a clue how to use it:

http://www.ldv.ei.tum.de/media/files...eg/sgi2yuv.zip

Got it now; change the file extension from .qnt to .yuv and load in RawSequence as pixel type UYVY (i.e. YUY2)

I tried to read a Y4M file generated by ffmpeg with RawSource, but I got a message "YUV4MPEG2 header error." and faild.
Thus, I challenged to modify RawSource a little.

rawsource.zip

Apparently, it seem that I got success in correspondence to the Y4M header that ffmpeg generate(include C tag) and YUV4:2:2 Y4M.
However, I cannot judge whether the method adopted by me is good because only five days has passed since I start the study of C/C++ language.
Please confirm and give me suggestions.

I use to generate raw yuv files with ffmpeg (not y4m) :
Code:
ffmpeg -i yuv_source -an -vcodec rawvideo file.yuv
These files can be read with rawsource, eg. for 720x576 (default size) :
Code:
RawSource("file.yuv", pixel_type="I420")
You can use a different pixel_type argument, and add width and height parameters to adjust size.

Interesting, could someone modify this plugin to read the 10bit v210 format, and display it as the common convertion, where image is double height, with MSB at top and LSB at bottom? In this case, we can now import nicely, the 10bit data and process with existing tools (dither, deband, etc.) and also output to 10bit encode (with avs2yuv and 10bit x264)?
http://wiki.multimedia.cx/index.php?title=V210

It's a pain to decode, but doesn't take too long (I've done it in script).
For samples,
