Video help

I bought a little Sony HD camcorder a while ago to start recording some of my kids events. When I try to play the video on my computer, the sound is fine, but the video is in slow motion. I'm not sure what I can do. It was suggested the problem was with my video card, or that windows is just not good with video. The files are saved as mp4. Do I have to convert it maybe? I'm clueless.

Any help appreciated.

Annette

    Does your PC/Video card play other MP4's OK?  What version of Windows?  Are you using MS Media Player or a different player?  Some more info on your PC might also help.  How much RAM?  What processor do you have?  Motherboard or PC manufacturer.  etc. 

    Should auld acquaintance be forgot--hey, who the hell are you guys?

    Hi Annette,
    I don't have a direct answer for you, but my best guess is that the proper codecs for MP4 may not be on your computer.
    Ordinarily, Windows is fine for video. MPEG-4 is a standard format, but has had some fairly recent changes. Your camera may be using a newer version.
    Did the camera come with a CD/DVD? If so, did you run it? It should have current drivers, codecs, etc.
    It should also have a player (Nero?). You might try that.
    I've never experienced that particular problem, but all of my stuff is older. Hopefully this helps some.

    I don't have the specs right now as the computer is in for repair. All I know is runs on Vista Home Basic. I tried running the videos on a few different programs. It wouldn't even open in WMP. One had sound, no video (VLC I think). I did eventually find one to play it, but the video was messed up.

    I tried my laptop this morning and it is playing in WMP. It was choppy at times, but I closed everything down but the player and it seems okay. The laptop runs on Windows 7 and is new this year. My desktop is a few years old.

    Hi Annette,

    Well that's a good sign that's it not your camera. 

    I'm afraid I managed to avoid Vista for the most part, I probably won't be much help with that. 

    What's the desktop in the shop for?  Maybe that will help your video problem.  One thing that may help and might be cheaper to do while the tech has the PC open would be to verify and add some RAM--if necessary.  It may not help your MP4 situation, but at least it wouldn't cost as much to do it as a separate trip to the PC DR.  Just something to think about. 

    Good luck,
    Jan

    Hi Annette,

    Often times the video from the camera needs to be converted before it will play smooth on a computer. This is usually because the camera uses a very specific and cpu intensive codec to squeeze as much info into the recording as possible. The camera has a processing chip that is made just for the task of recording and playing back that codec.

    For example; If I shoot HD on my HDSLR I have to convert the video I get from that camera to something else before it will play smoothly.

    In other words... you may have the correct codec and simply be pushing the playback engine too hard on your system.


    Final Cut pro has a feature known as Pro Res whereby the video you shoot with a camera is converted to an expanded size file that takes more storage space but is easier to play back with your computer cpu.

    I occasionally use Premiere. When I do I transcode to intermediary codecs made by a third party company named Cineform to playback and edit the video.

    Vegas probably has a good work flow for SONY HD too. :-) I'm just not familiar with it.

    If you want to play back or edit with systems that don't have built in transcoders you will need to figure out a free standing workflow.

    I know... it's a pain and it should be easier... or at least explained better in the camera manuals.

    The thing is... cameras use many different codecs and there are a variety of solutions as reflects each circumstance... so it is hard to give specific advice with out more info.

    What exact camera do you have? Maybe someone can suggest an easy transcoding solution.



    best regards,
    mike

    Since Mike has a better handle on the video aspect of your problem.  I'd suggest listening to him over my suggestions.  I'll take a more passive role and keep an eye on this thread.  I don't want to confuse the issue any more than I already have--too many cooks, you know.  I'll refrain from make too many more suggestions unless something really jumps out that you need to know. 

    Again, good luck.

    Thanks guys.

    Here is the link to the camcorder http://www.staples.ca/ENG/Catalog/cat_sku.asp?CatIds=&webid=911915&affixedcode=WW

    As for my computer problems, it was taking forever to reboot. The tech guy said he had no problems with it, but it would take hours to restart for me. He did say that the windows update isn't working and can't fix it other than doing a complete reinstall.

    Cheers,
    Annette

    Hi Annette,

    The link is asking me a question that only a Canadian will know the answer of.

    How about the model name etc. Then I can search it out on the Sony site?

    best regards,
    mike

    Oops and it's a Samsung, not Sony. See how challenged I am! Let's try this link...it's a Samsung HMX T10 Samsung

    Thanks for your patience.

    Re:Video help 2011/06/22 21:41:17 (permalink)
    Ok I, looked at the site. It's not very detailed with regards to the actual codec, but it is apparently a flavor of h.264 streaming at up too 50Mbit/s.

    Real life 720p h.264 files will drag your computer down. So that's probably why it is occasionally stuttering.

    That in itself isn't so much to worry about.

    What is your goal with video? For example; Even if you can't play it smoothly you can upload it to Youtube. Youtube actually converts what you upload to something that plays back smoother.

    Did you want to use the video on your computer or edit it? If so you will probably have to decide to transcode it to something that plays back easier. As I mentioned, the resulting files will be much larger because they are sort of half way decoded. The fact that they aren't compressed so much makes them play back smoother.

    If you want to do this you'll need to choose some type of converter or transcode software. There are many ranging from expensive to cheap. Some of the cheap ones are malware... so watch out for that.

    I usually use Quicktime Pro or my Cineform stuff...

    Maybe someone can suggest something cheap?


    best regards,
    mike

    As Mike stated, H264 is very cpu intensive for decoding and editing.  As an alternative, you may want to pull the video to your computer in DV format.  Most cameras have the option (look in the manual/menus) to transcode on the fly during transfer.  This way, you will still have the HD original in the camera but for working purposes you can have DV quality on your computer. This will let you fully enjoy your videos until you get a computer that can handle H264.
