Thanks for help

AVI, DVD, what?

[dinofava]

avi

Ah, well, some players (BSPlayer, MPC, among otheers, as well as ffdshow) can change the AR at playback to make it appear normal. For a permanent fix you'll have to resize and reencode.

To do that you can resize and frameserve into VDubMod using AviSynth, or do the resizing and reencoding directly in VDubMod. If you've never done this kind of thing before though, it's not all that easy.

[dinofava]

so there is no some easy automatic solution? i wanna watch it on stand alone dvd so i cant use bs player options

[manono]

Oh, so now you want to not only fix the AR of the AVI, but also convert it to a DVD for playback on your standalone DVD Player? The level of difficulty just increased. There are 1-click solutions for AVI->DVD, but I don't use any of them. And since the AR of the source AVI is no good, then I don't guess any of the 1-click solutions will work for you anyway. No, you're back to resizing and frameserving, either AviSynth into encoders such as CCE or TMPGEnc, or VDub into one of the encoders.

Maybe someone else will have a workable solution for you, but my advice is to give it up.

maybe a standalone with divx/xvid avi support.

give us more details, what is your source video? all details
do you want to convert to dvd-video?

[dinofava]

yes dvd/divx player of course

[dinofava]

i dont know details of the video it's movie.avi file. Where can i get info about a file?

[Baldrick]

gspot, avicodec, MediaInfo, VideoInspector

[dinofava]

i did it with mediainfo.

It looks OK. I would suggest your player is at fault, not the avi. A Divx player should play this back without distortion - it is a standard 2.35:1 AR.

Otherwise, ConvertXtoDVD will easily convert this to a DVD

[celtic_druid]

Check that the PAR with MPEG-4Modifier. Should be 1:1.

I didnt play it on stand alone player yet. I played it on win media player and mv2 player on my computer. And it looks streched vertically. I dont need to convert to dvd because my dvd player supports divx. Just want to change aspect ratio

it's "square pixels", if that's what you mean? I tryed both pixel and display AR with MPEG4Modifier but nothing happened. I can email someone small part of file, just tell me how to cut it (what software)

[celtic_druid]

Well if it is 2.35:1 and 1:1 then it should playback @ 2.35:1 which if it is vertically stretched would make it wider than 2.35:1 which is quite rare. Perhaps a screenshot would help?

[dinofava]

here is capture from video.

[celtic_druid]

Looks about right if you stretch it to fill 16:9. Cropped that gives you about 720x304, but without borders.

[dinofava]

Ok, but how to do it?

[celtic_druid]

That isn't stretched vertically by the way. It is compressed vertically or stretched horizontally. This is not good since vertical resolution is more important than horizontal.

Anyway, if you load it into MPEG4Modifier and set the DAR to 16:9 and save it should playback at 720x404 (16:9) or so and look about right. Other option is to crop the black and resize back to 720x304. Basically the same, but without the black bars filling it to 404.

Ok, MPEG4Modifier didnt do anything. Where can i try to do the second thing, with croping and resizing?

[guns1inger]

I put the image into photoshop CS2 using the NTSC template, and this image is very distorted. If that is your video, then it has been improperly resized to begin with. I dropped it into virtualdubmod, and set the display AR to 4:3. By using the resize filter, I resized it to 720 x 368, then added borders to fill out the frame to 720 x 480. This removed most of the distortion - note : it is difficult to confirm without some frame of reference. I based most of this on the face and the tennis ball.

Note 2 : The image below is now distorted slightly again, as it is shown with a 1:1 pixel aspect ratio, whereas my resizing was based on a 4:3 display. The same technique can be used as described above, but setting the virtualdub out to 1:1 first

[celtic_druid]

If MPEG4Modifier didn't work, that just means that whatever you are using for playback is ignoring the PAR info. Try it in mplayer or VLC.

[dinofava]

Since transforming it with MPEG4Modifier didnt work i tryed to do it with VirtualDub and i made it just pefect, but when I tryed to save "as avi" virtualdub started to render it again from start and made 20 gb file in several minutes (at only 20%). Since I didnt have more space left it aborted the process. Where i'm doing wrong?

I tryed it with mplayer and it looks the same as original.

[celtic_druid]

Well that means that either you didn't change the PAR or that the avi also contains ODML AR info, since mplayer will use this over a PAR. Would have thought that simply re-saving with MPEG4Modifier would remove such info anyway.

You need to select a video codec in VDub or you get raw RGB24.
