3vix video

[sofwhitewolf]

Ok i have a video in 3vix format, i have tryed alraedy what is posted in archives, but still no luck, super is the only thing i can find that even accepts the job but nomatter what settings i use it wont work.I am trying to convert it to dvd(VOB) but when i do so it lags, it will play and hten it will stutter, when i try and convert it to avi it doesnt stutter but the picture moves to fast for the audio, i have tryed setting the fps to 25 and still moves to fast for audio. Please any help would be great.

what is the source framerate? try identify with gspot or mediainfo.

[sofwhitewolf]

Gspot said it was unknown, but thought it was a quicktime MOV, mediainfo didnt show anything at all....Also it is a quicktime .MOV file, would you be able to put this on a dvd via data write and play it on a a dvd player?

[jagabo]

Use Media Player Classic to play the file, while it's playing go to Play -> Filters -> Video Renderer. The frame rate will be on one of the tabs there -- probably Quality.

[sofwhitewolf]

WMPC wont render the file

Hi,
You could try a freeware program called MPEG Streamclip you can find it in the "Tools" section of this site, It handles .Mov and supports 3ivx, you will also need Quicktime Pro or Quicktime Alternative. This program will convert .movs and Mp4's to DVD compliant MPEG-2's and if it will open your source file it should provide you with all the stream info you are looking for including framerate. I use it with QT Pro and it is very reliable, I can't say if it is as good if you use QT Alternative but QT Alternative is free to try it out on your file.

[celtic_druid]

MPC should play it fine. Just need to set qt to directshow or have the 3ivX qt plugin installed. For directshow it has a built in mp4/mov splitter and aac decoder. Just needs a video decoder such as ffdshow.

[sofwhitewolf]

ok the program you recamended streamclip works so far, but what is the best compression to use? the default is apple-photo Jpeg

[jagabo]

If you want to make a DVD, MPEG2.

[sofwhitewolf]

Well it dont even offer MPEG2 as an optiona and the avi size after the movie was converted was almost 6 Gb, why is it so big?

[jagabo]

It looks like MPEG Streamclip doesn't output MPEG2. Did you export as AVI? What compression codec did you select for the output?

[sofwhitewolf]

Yes i output as a AVI, and the defalut compression was apple-Photo Jpeg, so i just used that, and as i stated the total size of the avi was 5.6Gb

[jagabo]

Motion JPEG does not compress as well as MPEG 4 (3IVX) or MPEG 2. So the size isn't surprising. Since you've already done the conversion, can you open that AVI file with your DVD authoring software?

[sofwhitewolf]

yes i could, but the audio sync was off still so i deleted it, i was going to try and a differnt compression codec, or would the motion jpeg be best?

[jagabo]

Each round of compression/decompression decreases image quality. So it would be best not to use any compression. Be prepared for a very large file though.

I think you'll find that the audio sync problem is from MPEG Streamclip decoding your source. So the codec you use won't make any difference.

sofwhitewolf,
When you open your file in MPEG Streamclip open the file menu, there are several options to to Export to ie: "Export to Quicktime" "Export to DV" etc. Underneath the Export choices are several "Convert" choices ie"Convert to MPEG" "Convert to MPEG with Mp2 Audio" if the Convert options are grayed out then you are probably out of luck, if not I would try the "Convert to MPEG with Mp2 Audio" for starters. I haven't actually done this myself as I am usually going the other way converting AVI's and MPEG's to Mp4 and .movs but the program reportedly does both well, Check the MPEG Streamclip website for the best settings for DVD.

[sofwhitewolf]

Yes the convert options are grayed out, also the current size of it before i do anything to it is 1.3gb, and the current quality is dvd, so why would it get so big and lose quility when at the current size its dvd quality? i also checked and found out that the FPS is 23.97, and what i thought is would it work if i use super and convert to MPEG2 and set it to 23.98, since its MPEG2 wouldnt i be able to watch it on a dvd correct?

[GMaq]

...Your current file is 1.3 Gigs because 3ivx is an MPEG-4 codec and gives the approximate VISUAL quality of DVD at a far smaller file size because you are compressing the source more than MPEG-2 (DVD) would. It's not that MPEG-2 is better or worse it just works within far different compression parameters to give good quality. Because MPEG-2 is not as efficient (small) as MPEG-4 you will find that no matter what program you end up using the file size will be much larger when you convert your file to DVD compliant MPEG-2. If the "Convert" options are grayed out perhaps you don't have the actual 3ivx Codec installed on your system. Other MPEG-4 codecs like DivX,Xvid will playback decode 3ivx files but may not allow you to transcode 3ivx files to another format. Go to www.3ivx.com to get the Codec and try MPEG Streamclip again to see if the "Convert"options are still greyed out. You can try SUPER as well but I've always had A/V Sync problems with it.

[Ai Haibara]

According to the SUPER FAQ, at least as far as I've seen, you have to make sure that you select the exact same frame rate for the output video as the input video, to avoid sync problems.

[jagabo]

Saw this at their web site:

"For MPEG-2 playback and conversion, you need the QuickTime MPEG-2 Playback Component. You can buy it from Apple (www.apple.com/quicktime/mpeg2). If you have either Final Cut Pro or DVD Studio Pro, then the component is already installed"

http://www.squared5.com/svideo/mpeg-streamclip-mac.html

That was about the Mac version but they say something similar about the Windows version.

[BJ_M]

he is not playing mpeg2 on the qt player - anyway , the qt mpeg2 component is not needed and it is crap anyway ..

Ya i just want it to fit on a dvd, so at MPEG2 do you think it wil fit the 4.7G? also this is the video specs:

Duration: 2:23:10
Data Size: 1.36 GB
Bit Rate: 1.36 Mbps

Video Tracks:
3ivx D4 4.5, 712 x 352, 23.975999999999999 fps

Audio Tracks:
MPEG-4 Audio stereo, 44.100000000000001 kHz

Stream Files:
Myvideo.mov (1.36 GB)

[jagabo]

Yes, a 143 minute movie should fill a single layer DVD. Use a video bitrate around 3500 kbps.

[sofwhitewolf]

ok if i change the video bitrate, should i also change the audio bitrate?

[jagabo]

You will have to change the audio to 48 KHz sampling. With AC3 encoding anywhere from 192 to 256 kbps is fine for stereo audio. You can use a bitrate calculator to determine exactly what bitrate to use for the video. And with such a low bitrate you definitely want to use a 2-pass (or more) variable bitrate encoding.

[sofwhitewolf]

ok i went ahead and ran it through super at the rates above, and burned it and for the most part it looks ok, the sound is in synce, but the picture looks cloudy, like squared boxes kinda

[jagabo]

That sounds like macroblocks -- a result of too little bitrate. Did you perform a 2-pass, variable bitrate encode? A single pass, constant bitrate, encode will result in more macroblocks.

[sofwhitewolf]

im not sure, but anyhow it is good enuf thank you all for your help
