Display Aspect Ratio ?

[KingCraft]

I'm having a problem with output DAR from Vegas pro 13.0.

After recording a TS file, I used MeGUI converting it to MP4 because Vegas can't import TS.
My problem is that I can't obtain the same output DAR after rendering with Vegas.

I'll show you the results and hope someone tell me what have gone wrong..

Well I have never heard of that Vegas could not import a .ts file.

Well 720*576 is 5:4 but you clearly have not got your ouptut settings correct since your file is now NTSC rather than the PAL input.

[DB83]

If that is the case, and I still do not believe it, you would have been better to create your mp4 as 768*576 PAR 1:1 which is true 4:3 rather than force it through the DAR which might be fooling Vegas.

There are few (if any) export settings in Vegas that do not allow you to manually set the pixel and/or display aspect ratio. Try again

It is?? 720x576 at 25fps seems pretty PAL to me.

Hehe, he's referring to the third picture in the OPs opening post which for some odd reason shows the output to be NTSC.

Is that just some MediaInfo oddity?

I guess I don't quite understand MediaInfo's definitions of "Standard". I just checked some PAL DVD video which I'd remuxed as MKV and expected to see "Standard: PAL". For all the episodes from season 6 up, that's what it displayed, but for the first five seasons it displays "Standard: Component". It's all interlaced 4:3 PAL DVD video though.

I tried a few short re-encodes without resizing or setting the correct display aspect ratio but MediaInfo seemed to always consider the output as PAL.

That was very helpful mate thanks
Processed again with MeGUI (720x540) 1:1 and everything is ok.

wasn't sure about resize filters so I didn't use any, just resizing to 720x540 which gave the best results.

Not a good way of doing it for many reasons:

Quality at loss each stage, lossy intermediate formats

Wasted time

Becareful of interlaced scaling issues - you can't just resize vertically to 720x540 from interlaced 720x576

Also, any scaling causes quality loss




Best would be to import the native files in vegas . If it doesn't import , try re-wrapping it with tsmuxer, or putting it into a mpeg2 program stream (.mpg) with ffmpeg .

Even if you couldn't do this, you can change the aspect ratio interpretation in vegas. All 3 must be correct : The clip interpretation AR, the project settings AR, the export settings AR. You messed up one or more of them

After re-muxing with tsMuxer, I was able to import it finally into Vegas.
Thanks for help
