It is a BIG BIG question for me!!!

I have used PowerDVD9, 10, 13, 14 and now 15, I still don't understand why all MPEG 1 video is not played in 4:3 ratio???

It is that easy and all knows the flag of MPEG 1 must be played in 4:3!!!

Can Cyberlink nicely fix this simple problem pls.

Hi, I downloaded that file and it is not 4 by 3. I played it on 3 different players (PowerDVD 14, VLC and Windows Media Player and got the same display -- black bars on either side. My monitor is 16 by 9.

What problems are you having with it? .

Steve, try to post sober my friend Ofcourse your going to get black bars left and right on 4:3 full frame video when on a 16:9 monitor!! Steve I suggest you could do with some reading up on SAR, DAR, PAR System Aspect Ratio / Display Aspect Ration / Pixel Aspect Ratio

The video is correctly 4:3 fullframe 1.33 aspect ratio. As per:

nullack, Why not answer the question rather than to berate me? Wit until the original poster tell us what his real problem is.

The video is 1.47; not 1.33 aspect ratio. I of course expected the vlack bars on the sides with my moniot. I'm just trying to get more information anbout why this is a major problem for the OP.

Steve the OP is a making a statement, which indeed is a true statement. You claimed it was false when you claimed that you downloaded the file and "it is not 4 by 3". Its you who is wrong. The ffmpeg probe output I shared showed you to be wrong.

Youve gone on to say another false statement which is "the video is 1.47".

The reality is that the footage the OP shared is fullframe 4:3, which is an aspect ratio of 1.33:1.

Hes simply and correctly saying, hey cyberlink, fix your buggy stuff thankyou. Keep in mind also, the free to own and distribute open source players get this right out of the box too. And as well, deinterlacing also just works, unlike in PowerDVD.

I get that your an enthusiast who wants to help. For you to offer help on these subjects, you need to understand the subject yourself.

nullack - You are reading a lot of information in the posts that simply are not there. Perhaps the OP needs you to be less full of yourself and provide help.

Do you know why the OP needs the 4 by 3 video to play (apparently in a 4:3 monmitor? and why it is a problem for him? I don;t see his post being where Cyberlink must fix the perceived problem. If so, the OP should know that they can contact Cyberlink directly.

I stand by that the video is 1.47:1. (Windows Media Information) --close, by not 1.3:1. and everythign else I posted.

Can you guess any reason that the OP has not com back to look at this thread?

Do you ever have anyhting positive to say about Cyberlink? If not, why do you still come here to the forums that are designed to HELP other users.

At this point we need to stop sniping at each other and agree to disagree. Stop criticising my posts and questioning my lifestyle (I don't drink).

Help the users ! (even if it is just to say to contact Cyberlink Techincal Support. .

Steve its false to suggest the video footage is not 4:3. Windows media information is not parsing either the video stream itself or the headers correctly and is well known for not being correct. Moreover, multiple toolsets that are known to work, the OP mentions medianfo which gives 4:3 based off the headers. I ran ffprobe from the ffmpeg project as you saw, which gave a display aspect ratio of 4:3. ffprobe analyses the video stream itself regardless of the header. Use tools like mediainfo and ffprobe for this stuff. The video stream is the definitive way to tell since sometimes poor muxers can produce containers with wrong header info.

Steve I dont have any personal issue with ya mate. I thought you'd get the friendly prod about not posting pissed in the humour it was intended. For the record I think on a personal level your a nice fella mostly. The technical stuff, well theres no other way to say it other than your wrong But thats OK, like all humnan beings were wrong from time to time.

You have made me sink to your level and I don't like myself for it. I apologize for my comments. I will just stay clear of your postings.

Hi Chi-Yip,

Please click the "More Video Settings" button in "Video, Audio, Subtitles Settings" to access the additional Settings.
Than on the Aspect Ratio tab click "Always maintain video aspect Ratio".

The reason why all Videos are played to the screen size is that the option "Apply stretch" is the default choise.

Greetings

That particular mpeg-1 file uses non square pixels. The 352x240 video is typical of the vcd format say 20 years ago.

nullack - You really know your stuff. I haven't messed with vcd since the turn of the century.

Hi tomasc,

The reason why all Videos are played to the screen size is that the option "Apply stretch" is the default choise.

Launch the clip in PowerDVD and right click on it, choose than "Aspect ratio", than "Keep aspect ratio".

Or you can change the default choise "Apply stretch" to "Always maintain video aspect ratio".
Now all your files will be played in there original sizes.

Kind regards
