  1. Hello guys
    I have a pretty old CPU(pentium 4 2.40ghz several years old) and GPU (FX 5500 with drivers from april 2004 xD) and of course it's nearly impossible to watch 1080p movies/videos.
    However, 720p moderate videos are smooth.
    That's why I used VirtualDub to resize the resolution(for 1080p AVI files) to 1280x720 or something and compress it.
    But recently I've downloaded a 1GB video file, 720p with a .mkv extension. (the previous ones that were smooth had sizes of 500/600MBs)
    It was very choppy(I had older version of K-Lite codec pack) so I thought it could be the codecs. I've uninstalled them and installed the newest version of K-lite mega pack.
    Then the video was somewhat smoother(it still had choppy moments from time to time) but the audio was lagging for like a second or something.

    Anyhow, the thing what I want is... a software that compresses MKV video files,(or) a software that can convert MKV to AVI and then I compress it with VirtualDub(tried to do this with some programs but VirtualDub still wouldn't open the AVI) or a software for resizing the resolution of a MKV video file.
    If I'm not clear in what I actually wanna do... I want to make the video size smaller(down to around 700MB ) and I think it will run smooth... in case it doesn't then I wanna resize the resolution of the video to 960x540 or something

    Where shall I post this?
    Thanks in advance and sorry for 'newbieness'


    P.S. I'm sure the video is fine cuz it was smooth when I tried it on a better computer at the local internet caffe

    If your computer is that slow, converting that MKV may be really, really slow. MKV is a container format, probably uses a highly compressed H.264 codec inside. You have several choices. One is a better video card, but you probably have a AGP interface and card choices are a bit limited. You didn't mention what software you were using for playback, but the freeware MPC-HC would be what I would recommend trying.

    You could also convert the MKV to DVD format. I use ConvertXToDVD for that, but there are other programs that may also work. Or the freeware XviD4PSP may work for converting to a different AVI type format and changing the resolution. VirtualDub is not the best tool for those type of conversions. And I doubt K-lite will help you at all.

    And you may be able to see what's inside that MKV container with MediaInfo. I suspect the audio is also a high quality/compression format.

    And welcome to our forums.

  3. Hi and thanks for the reply.
    I know it would be slow.. like 8 hours or something right? New hardware is out of option until early 2010
    I'm using several media players:
    bs player
    gom player
    mv2player
    media player classic
    vlc media player

    The video is the least choppier on mv2player.
    I'll try to convert it to DVD. Could you tell me more about what I need to do in ConvertXToDVD because I've never used it. I'll try myself but it's better to listen from someone with experience. But wait, if I convert it to DVD wouldn't it be actually bigger size like 4+ GBs?
    Also, does the trial version of ConvertXToDVD is only limited to number of days usage or it has video time limitations?

    Thank you for the welcome

    Yes, ConvertXToDVD will give you a DVD size file about 4.37GB, but it will be compatible with most set top players as a DVD, if that's what you need. It may leave a water mark. I haven't used the free version for a while.

    XviD4PSP or similar may be a better choice. From MediaInfo, your file may be small enough in resolution already. You could try converting it to a Xvid or similar with a program like XviD4PSP or similar. But I would try MPC-HC first to see if it will play back better. It's optimized for MKV playback. It's not the same program as MPC.

    When you get a faster CPU/Video card, it will be much easier to play back MKVs. And much faster for conversions.

  5. Hi redwudz
    With MPC-HC it still lagged.
    I got all the tools(xvid4psp, framework, avisynth etc) on an USB and went to the local internet cafe. I know the guy there for few years and he let me to encode it on his computer while he was just browsing the internet. The encoding took 3h and 20 mins. The video now is 900mb. It lost only a bit of the quality. It doesnt lag on my computer now but the audio still has some bad sync(but it's better than previously). Now I also tried to open the avi with VirtualDub and I could. I think if I lower the resolution to 960x540 the audio will be fine.

    Thanks to this Xvid4PSP application and THANK YOU VERY MUCH for all the help. You are awesome.

    The 'bad sync' problem may be from the DL'd video. Some uploaders don't do a good job of conversion.

    The higher compressed formats like H.264/MKV take a lot of processing power to display and to encode. But they are very efficient for size VS quality.

    When you upgrade your CPU/Video card, those MKV files should play much better.

    you are wasting your time attempting to down size/re-encode the movies, first of all it will take a ridiculously long time to do and second when you finally do get a faster setup that can handle the original 1080p files you will be kicking yourself for not keeping them in their original format.

    i understand that times may be tight at the moment and a new system may be out of the question, but can you afford $40? if so pick up one of these:

    http://www.newegg.com/Product/Product.aspx?Item=N82E16814133245

    it's more than capable of playing back 1080p vc-1, divx, mpeg-2 and h264, it uses the PCI interface (not PCI-E) so it will definately work with whatever motherboard you may have and it fully supports CUDA:

    http://www.nvidia.com/object/cuda_learn_products.html

    so even if you decide you still want to re-encode to a smaller size you can take advantage of a CUDA accelerated encoder like Cyberlink's Power Director, Badaboom or the excellent and open source Media Coder.

    with that set up you should be able to achieve roughly 20fps going from 1080p to 720p, which will certainly be a massive step up from what your setup if currently able to do.

  8. @redwudz, the audio has no sync problems at the cafe

    @deadrats i might be wasting time, that's what some other folks said but i didn't know anything about encoding and stuff and now at least i know some basics(also the whole process was fun for me)
    when ill get a new comp, i won't be watching the same movies like now

    thanks for the recommendation but im planning on buying a high end PC in the first quarter of 2010

    A 2.4 GHz Pentium 4 will encode 720p at like 2 fps max, 1 fps if you count the decoding and resizing of the 1080p frames which comes to about 40 hours of encoding for a 90 minute movie. You are wasting a hell of a lot of time. Unless you live in a shithole with no heating and you want the winter to keep your CPU cool, I can't name a reason why you shouldn't upgrade immediately.

  10. ok you know better than me when I should upgrade....
    i request this thread to be closed if it's possible

    Request denied.

    I'm making a joke at your expense here, but seriously, threads ONLY get closed for spam, cross posting and maybe violation of terms of agreement (ie. talking about warez). Your thread won't be closed. In fact, months or years later some idiot will probably dig it up and post to it on something vaguely related to your original post. Or if you want to be a complete jerk, you can actually go in and delete EVERYTHING you have posted in this thread and just leave huge blanks on your posts. You can't delete what others have said, but you can delete what you have said. I think this is idiotic that it is possible to do that, but we had a loser do that in one of the biggest threads in the forums. He got angry about something (nobody here knows what it was) and he went through a thread that had over 500 posts in it, with probably about 500 of them from him. It was about some specific models of DVD recorders. He deleted EVERYTHING he ever said in EVERY post he ever made and instead in each post put a link to another forum on another website. I think that the forums should not allow such actions, but they do.

    Try using the CoreAVC codec. It's made for slow computers. It allows many to play mkv's smooth. Many people have great results.

    Wait up, the suggestion to upgrade immediately was rhetorical. Waiting or simply buying a cheap alternative for the timebeing would be smarter. All kinds of new processors are gonna be released by Intel and AMD in early 2010. In the meantime, lay off watching HD movies and do something else.
