    hi there....

    Is there anyone who can help me out finding some raw data files in y4m format

    Re: y4m raw files

    What device/program produces such files?

    As far as a quick google search revealed y4m is a video format/container.

    Edit: a further google search revealed this page:
    http://www.quavlive.com/video_codec_comparison
    on it theres a link to a 1,5 GB raw y4m video file. Apparently just 20 seconds so I'm guessing y4m is lossless video... eeep...

      There were more of them on that site;
      Here's one with about half the filesize (10 second clip): http://media.xiph.org/video/derf/y4m/1080p/riverbed.y4m

        Hi there...

            No problem... but if you need y4m ("input") files to test, then that's what I linked I think...

              Yes... U have sent me y4m file link.. But the one which you have sent is the same I have used earlier but my TL mentions that I need to have more input files.. which I was not successful in finding.. The other link which u have posted ie http://www.quavlive.com/video_codec_comparison few of them require resolution required which is 4:2:0....

                Hmm... besides googling for more, maybe you could create some dummy files? E.g. convert a still image or some non-raw video to y4m?

                  but the program accepts only 4:2:0 resolution and I m unable to convert the files.. I have tired using some on line software to convert them.

                      Hi I am interested in using x264 encoder to compress videos at different bit rates. The video I want to convert are mostly in FLV and mp4 formats. Can you please suggest how to convert these videos to y4m formatm so that x264 can compress them for me?

                      Thanks in advance...

                        The other part of my task is to transmit these compressed videos through the internet to some host and then decode them. Can you please also mention some good decoder to convert the .264 compressed videos back to .y4m?

                        Thanks,

                          how do you open MOS files?
                          by Caravaggio
                          Does anyone know how to open MOS files not using Capture One? MOS files won't open in CC camera raw for me. Under get info it says that it is a Leaf RAW image.
                          I had a free trial to Capture One, but it expired and I am not eager to purchase it.
                          Thanks for your help.

                          Downloadable sample RAW files
                          by Doug Nelson
                          Does anyone know of any sites where we can download RAW files in the various native digital camera formats? I've looked on the Nikon site, Canon site, etc., but can't find any downloadable RAW images (they might not end with .raw, I know).

                          100MP Raw Files
                          by creativeretouch
                          I downloaded sample 100MP Raw Files (IQ3) - and my first question was - "OMG, how long it is going to take me to retouch one image?" What is your opinion?
