W3Exchange / Aspect Ratio?

super_encoder · 2006-09-15 05:06:25

I just started using Super yesterday and am very pleased with it's speed and quality. I want to encode some mpeg-1 videos and burn them to a dvd-rw to play in my standalone dvd player, and for the most part this works fine. However when I encode an Anamorphic 16:9 source video, no matter what I set for Scale Size, or Aspect Ratio, the output video is stretched vertically to fill the screen like If I had my dvd player set to 16:9 ratio. I don't by the way. Windows Media Player plays them correctly, but Powerdvd does the same ugly looking vertical stretch. I looked under the video information bar in Powerdvd's config menu and it says aspect ratio unknown. Is there anyway to fix this, so that my widescreen video retains the widescreen look?

You just said:
source is 16:9 --encoding into--> output video set to 16:9
so, where is the problem? this is a true rendered output..

The problem is I have a 4:3 standard TV. The video is not playing like a widescreen movie with black bars does on a 4:3 tv, it is playing with the portion normally inside the black bars, stretched to fit the TV. It looks strange.

May i suggest that you encode a small portion like 1 to 2 minutes using 4:3 Aspect Ratio.
Select Other Opts and check the "Encode Only For A Total Duration Of xxx Sec"
Selecting 4:3 or maybe 11:9 could give acceptable results. Why don't you try?

I'll try that but in the meantime I noticed something, my encoded audio is 2to3 seconds ahead of the video, and I am positive I am encoding at the correct framerate. Wait, just double checked and they play perfectly in sync on my computer, but not on any of my families 3 dvd players. I've burned mpeg-1 video made by programs such as DVDx before and they were in sync, not to bash the program or anything, but why is that? I just noticed DVDx has an audio/video synchronization option. Does super have anything similar?

Is it VCD, SVCD or DVD output that you are burning? you didn't specify.
In all cases, all our internal tests were conducted using NERO for burning
and using TMPGEncDVD Author for DVD Authoring and Menu creation..

You should know that when selecting VCD, SVCD or DVD output container
the FPS is auto-selected according to the VideoScaleSize as per the standard.

PAL output has standard defined VideoScaleSize, NTSC output has other
standard defined VideoScaleSize, you CANNOT mix them..

I installed Super yesterday and have had wonderful results, however

My seetings are:
output container: vob dvd compliant
video codec: mpeg2
audio codec: ac3
using mencoder

Yesterday, using a 16:9 source, if i set the aspect ratio to 4:3 the image size would be 4:3 and super would automatically add the letterboxing, black bars on top and bottom. Alternately if I set the aspect ratio to 16:9 there would be no black bars and the image size would be scaled properly. Perfect.

Today, if I set the aspect ratio to 4:3 or 16:9 the image size is properly scaled, but in the case of 4:3 there is no longer any letterboxing and the video image is stretched vertically full frame.

I've tried uninstalling and reinstalling after deleting everything relating to Super in the hope of solving this problem, but to no avail.

Any suggestions would be appreciated.

Regards,
Alph

It depends on:
1.The Aspect Ratio of your input source file
2.The setting of the Aspect Ratio selection
3.The setting of the Stretch it option
4.The setting off the Crop/Pad option (Right-click, select the "Show hints" option, hover your mouse over the "C" button of Crop /Pad and read details.)

uninstalling and reinstalling SUPER(C) is a waste of time.

Thank you for the response

Today's files are, as yesterday's were. 16:9, and I'm trying to create letterboxed 4:3.
The stretch it option changes nothing.
Crop/Pad is disabled with mencoder. I tried using it with ffmpeg, but all it did was add padding above and below which resulted in a frame height greater than 480.

I did a lot of testing with 15 second clips, but I conceed that there may be a setting I'm missing as I am new to SUPER (C).

I'll keep poking around.

Thanks,
Alph
