  1. Hello,

    My company's website allows its members to list videos of their work online on their own personal 'press kit'. Until recently, we allowed them to upload several types of video onto their pages, but we've now changed our policies and incorporated an flv only video player. Any new video that's uploaded is automatically converted to flv upon upload - however, we still had about 2000 old videos left in non flv state.

    I've been converting these non flv videos to flv, and have had pretty good success with using my websites upload converter or if need be, sothink video encoder for adobe. However, .mov's have been causing the biggest trouble. The two common issues are that the videos won't fit into the flv video player upon conversion/upload(see attachment), or the sound comes out garbled. With these files, I personally convert them to flv before uploading, to ensure they'll play/fit properly - but the problem usually persists. In the screenshot I've attached, you'll see a video that I converted into flv, into the proper dimensions 320x240, yet no matter what I do it'll appear smaller than it should be, and in the corner of the player. Is there some secret to converting mov's to flv's that I don't know about? I've exhausted every possible solution I could come up with, including converting with larger dimensions, playing with the zoom function, converting the files to another format before converting them to flv - and the outcome is always the same. No one here seems to know a solution so I'm asking for expert advice. The only other thing I can think of is that it's something with our uploader itself, but I don't know how to figure that out/get our tech department to fix it.

    Here are the flv requirements that I'm aware of on our player -

    The conversion process will change the size of your video to 320 x 240 if it's not that size already. Also, the "audio sampling rate" of the video must be 11025 hz, 22050 hz, or 44,100 hz. Otherwise the audio may be garbled on playback.

    and here are the sothink specifications that have worked for (almost) all other file types -

    Profiles: User-defined
    Audio Settings
    Enable audio-Checked off
    Sample rate: 44100 kz
    Bit rate: 96 Kbps
    Channels: Stereo
    Gain: DO NOT TOUCH
    Video Settings
    Width: 640
    Height: 480
    Bit rate: 350
    Frame Rate: 30
    Key frame rate: 12
    Zoom mode: LetterBox

    any direction you can give me is greatly appreciated - including other software, other specifications, ect. Thank you!!!

  2. flv and mov are container formats that can store multiple different video & audio types. It's quite non descriptive. It's like saying "car" . But "car" could encompass a Ferrari, or it could be a Yugo - but there is a big difference between the two

    You need to provide more information on the input type and export goal (ie. what kind of mov, what kind of flv? what type of video & audio compression).

    Use mediainfo

    Try a FREE and better convert than sothink crapware. Like xmedia recode.

  4. haha thanks for the tip - I personally don't like Sothink either.

  5. I apologize for my lack of knowledge about these video types, but I'll try to answer you question as best I can. Unfortunately I wasn't able to get as much information about the flv specs as I'd like other than the info I provided above. Our tech department has limited knowledge about videos, which is why I'm coming to you guys. If you need me too I'll continue to press for more information, but please let me know what to specifically ask.

    As for this specific mov file, I've uploaded it so you can see it for yourself. Please let me know if you need any further information. Thanks!

  6. sorry, the flv specs i provided may have been confusing because i copy and pasted from our upload page. here is the only information they've given me -


    dimensions 320 x 240
    44,100 hz
    file must be under 30 MB

  8. You can use the program suggested above, mediainfo . Open a flv that you know works with your system , and use view=>text, copy & paste the information back here

    I played with your sample mov , and found a possible solution but it's quite convoluted. I can go into detail, but I can tell you it will be way over your head if you're not already familiar with some of the tools like avisynth . Hopefully someone else can find an easier solution.

    The problem is most of the tools do not decode that mov corrrectly (as depicted in your 1st screenshot), and they pass that on to the encode. If you decode through the quicktime API, then you can get a proper sized image

    For now,
    1) can you test if this attached flv is compatible with your system (i.e. does it play in your company website player correctly) ?

    2) please post the mediainfo text information requested earlier

    3) do all the mov's that you have problems with exhibit the same characteristics? or are they a different kind ? (i.e. you should use mediainfo on those too)

    I think you're onto something here. When I tried to convert with two different pre-compiled ffmpeg binaries, the result for one copy did show the bad decode (~2/3 size in upper left corner), while the other did a good decode. The difference must be in the compile options and/or versions. For some reason that I can't detect, the first ffmpeg thinks the source file is 352x288 [PAR 12:11 DAR 4:3]. The second correctly detects 240x180.

  10. If you can figure out what that particular ffmpeg version was compiled with , or even list that version or binary for the OP, it would be alot easier for him . He could even use a batch file to convert everything

    Something might be different between the libavcodec decoder between the versions you tested out on . If you -s 320x240 on the working version, does it scale correctly and create a working file ?

    I used Mac OS binaries of ffmpeg as used by (1) MovieConverter Studio 1.5.3 and (2) ffmpegX 0.0.9y, so I doubt the OP could use those directly.

    I used the same simple syntax for both: ffmpeg -i input.mov -s 320x240 output.flv . Adding more detailed parameters didn't make a difference for the decode error. Scaling to other sizes kept the ratio of the small movie in a larger black canvas, confirming the decode aspect of it, imho.

  12. but scaling for the "working" version works correctly ? ie. it's decoded correctly and scaled correctly ?

    which was the one that was working? I can test r16722 windows build if that's the working version

    if it's the ffmpegx version, it's using a really old version of libavcodec , would have to go far back to find an old ffmpeg build

  13. I found a GUI based solution for this which would be easier for him to use

    Apparently you can do batch encode if you use command line interface (not sure how to do that in avidemux , but you could ask in the avidemux forum) , because it would suck to do 1 at a time if you have a few thousand...

    video=> sorensen spark (configure your bitrate if you want)
    video=> filters => resize to 320x240
    audio=> mp3 (lame) (configure your bitrate if you want, and resample to 44.1Khz if you want)
    format=> flv
    press save with extension (e.g. "myvideo.flv")

    Yes.

    Unfortunately, the newer ffmpeg from MovieConverter showed the same symptom as the OP's initial conversion. The older ffmpegX binary decoded and scaled correctly.

    A solution should come from new/current releases, not old ones...

    kind of like how new coca-cola was better than the original right ?

    I agree with what you say, but if it's a persistent bug that got propagated, I think it would be better to identify what the underlying problem was in the first place and patch the new ffmpeg builds . You would have to look at the old ones to do that.

    ffmpeg would be ideal for the op's situation, because of ease of batch conversion . The other 2 possible solutions I suggested earlier are not user friendly for multiple files (avidemux might be ok in CLI mode, and you can batch script avisynth and use ffmpeg to ENcode)

  16. Most of what you're talking about it over my head! But thank you so much for taking so much time looking into this weird problem.

    I tried to upload your video to our site and unfortunately the size issue persists.

    I've converted these other types of files - swf, wmv, wma, rm, ram, mpg, mp4 and avi. I did have a couple problems converting a few of the formats here and there, but could almost always fix the issue by converting to flv with sothink first.

    Other problem upload details -

    1. This mov file fits properly but the sound remains garbled upon upload

    After speaking with our tech department again, it seems that every video uploaded in flv should be compatible with our player, and if it doesn't it's a problem with the upload or the file is corrupt. Based on my experience with our flv player, it appears that our player is compatible with a wide variation of flv settings, and that these problem videos are somehow outside of that range. So I'm not sure if providing you with the description of a single working flv file with help. Here's info on three videos that were uploaded in flv format and play perfectly -

    I played with your sample mov , and found a possible solution but it's quite convoluted. I can go into detail, but I can tell you it will be way over your head if you're not already familiar with some of the tools like avisynth . Hopefully someone else can find an easier solution.

    The problem is most of the tools do not decode that mov corrrectly (as depicted in your 1st screenshot), and they pass that on to the encode. If you decode through the quicktime API, then you can get a proper sized image

    For now,
    1) can you test if this attached flv is compatible with your system (i.e. does it play in your company website player correctly) ?

    2) please post the mediainfo text information requested earlier

    3) do all the mov's that you have problems with exhibit the same characteristics? or are they a different kind ? (i.e. you should use mediainfo on those too)

    That uploaded file conforms to Adobe Flash specs and plays fine in several flash players including, embedded flash players, and stand alone flash players.

    It seems like your software has issues with AAC audio - all the examples with "garbled audio" had AAC audio . There doesn't seem to be a consistent pattern behind the size issue

    Can you test this attached avidemux converted file?

  18. That worked!!!! Thank you for fixing that. What can I do on my end, or is it too complicated? <3

  19. What worked? The "avidemux.flv" version ?

    If so, I posted instructions in post #13

    I don't know how to use the command line version, but it might be possible for you to batch convert them (e.g. all the files in a folder) , instead of 1 by 1

  20. Great, I was able to do it on my own. It's probably only about 100 files so I can do them one by one.

    You mentioned a problem with our player and AAC audio - what can I do to fix the garbled videos (i'm assuming using avidmux with the MP# setting but I could be wrong) And is this something I should bring up to tech to try and fix (could happen to other people)

  21. Does your software re-encode the user uploads ? like youtube ? or does it take the ones unaltered (not re-encoded) ?

    The reason I say it has problems with AAC audio, is all the examples you posted that had "garbled" audio used AAC audio

    AAC has been used for years now in flash, which is another reason why I suspect the programs used by your website are quite outdated

    There is nothing you can do to a video that has garbled audio already.

    But if you have a non garbled source to begin with, you can use MP3 audio, like the example above instead , or tell your users not to upload videos AAC audio . Or better yet, update the software on your company site. The video & audio compression used is very poor and outdated (translation: low quality and waste of bandwith. Your company could save money in bandwidth costs and exhibit higher quality video & audio by using modern technology)

  22. Thanks!

    We only alter the file if it's not in flv upon upload. If the file is already in flv, I believe we don't change it at all.

    I've been informed that we currently use '.NET media handler pro' is that a bad choice? Or do we just need to update our software? I may be able to recommend something else if it works better, as we do occasionally have problems upon upload.

    I just converted a mov file with the resizing issue, but now the audio is garbled! I'm sure I'm using the wrong setting or something. I did MP3, resampling 44100, bit rate 96. Is this wrong? Here's the original file's info -

  23. The difference in the audio between "avidemux.flv" and your version is it used a higher bitrate 128kb/s and didn't resample audio to 44.1KHz . (It stayed at 22.05Khz unchanged) . The video bitrates are different as well , but that shouldn't affect the audio

  24. I am not an expert, but, still I would like to try...

    Following is converted FLV, using FFMpeg CLI.
    I guess, same thing can be done by using Mencoder too... I will gonna try Mencoder later at my ease.
    It can be streamed nicely to 240x180

  25. thanks for all the help, it's greatly appreciated.

    does anyone have a better suggestion for our conversion software on our website? we currently use .net media handler pro, but I'd like to forward any suggestions for a better program onto upper management. thanks!

  26. if you know java or php scripting use CLI to batch convert all.

  27. Sorry, if I'm completely ignorant about what you're saying. Our website using media handler to convert any non flv files to flv. Is there a specific program/company that would be best suited for this job, or at least better than .net media handler? Thanks
