Here's one where the files are already in YUV format.

How about trying the command-lines I gave you last time to create your own raw yuv files? Much faster than downloading huge uncompressed files from the internet.

And why not frameserve some losslessly compressed files into x264 instead of uncompressed YUV files? For example HuffYUV or FFv1.
This will save you a lot of diskspace and HDD activity...

Well, looks like there actually is a way to access the test sequences at ftp.ldv.e-technik.tu-muenchen.de. The server doesn't seem to like Firefox or wget, but ftp works for me on Linux. Maybe some graphical FTP clients work too. Login as "anonymous" and go to dist/test_sequences/1080p. |

These files have sizes of ~1,5 GB each, so I cannot upload them for you. I'd probably run into the 24h disconnect

Here's a wget line to download one of the files directly: Code:
wget --no-passive-ftp ftp://ftp.ldv.e-technik.tu-muenchen.de/dist/test_sequences/1080p/tractor.yuv |

The command prompt is your friend. Stuff to type in pointed to by arrows.
I'm getting about 2 Mbps sustained from the site. Takes over an hour to download 1 file. Ron

That won't help if he's behind a NAT router, where he can't accept any incoming connections from the FTP server
But this will be required for the "active" mode (PORT command) of the FTP protocol. The "passive" mode doesn't work with that server. Probably because the FTP server itself is behind a (wrongly configured) NAT router...

http://www.w6rz.net/qnt2yuv.zip usage: qnt2yuv <horz> <vert> <prefix> <outfile> <interlace> For example: qnt2yuv 1920 1080 NM_ newmobile.yuv 1 It will convert each file starting an NM_00000.qnt until it can't open an input file (in this case, NM_00302.qnt). Since the program is performing 4:2:2 to 4:2:0 conversion, you have to specify if the input file is interlace (1) or progressive (0). Ron

You can extract a section from a YUV file (raw YV12 data) simply by truncating the file. The size of one frame, in bytes, is:
size_frame = (width * height * 12) / 8 So if you want to cut out the frames a to b, skip the first (a-1) * size_frame bytes and then copy (b-a) * size_frame bytes
