Hi all,

I found some topics about 16:9 issues already, but none really describes my problem, even though I would think my problem is a pretty common one.

Input: H.264 video and AAC audio in an MP4 container. The resolution is 720x576. It is widescreen content, so it should be played back at 16:9. Just like in the attached file called "mpc.jpg".

Desired output: a 16:9 DVD.

So, I open AVS Video Editor and first set the project aspect ratio to 16:9. See "16x9.jpg".

Then I add one of my videos. It asks me whether I want to change the project aspect ratio to the aspect ratio of the file. Well, yes and no. Yes, because the file is supposed to be played in 16:9 as well. No, because AVS Video Editor thinks my file has an aspect ratio of 5:4.

So, I choose no. And the result is what you see in "wrong1.jpg". The imported file is incorrectly shown as 5:4, while it should be stretched to 16:9.

If I would have picked "yes", then the project aspect ratio would change to 5:4, which is wrong. My project is 16:9. So that's not an option.

So.... the main problem I think is that AVS Video Editor thinks that my video has an AR of 5:4. See the file "wrong2.jpg". How can I tell AVS VE that my imported video's have an AR of 16:9 instead?

Cropping is of course not an option. The whole 720x576 pixels should be stretched to 16:9, just like what a DVD player does.

At this moment I feel like I paid $59 for a video editor that is unable to properly handle widescreen 720x576 content. Please tell me I'm wrong.

Regards,
Gerben

Oh, by the way, can someone update the topic title to "16:9 content loads as 5:4"? The content is not DV and 4:3 should be 5:4. Tnx!

Hello,

Sorry, but 720x576 is not a widescreen video. It correspons exactly to 5:4 aspect ratio. However, usually such resolutions as 720x576 and 720x480 are used in DVD format and correspond to 4:3 and 16:9 aspect ratio. If you want to make 16:9 DVDo from your mp4 video file without black bars, try setting 5:4 aspect ratio for the project and save resulted video to DVD NTSC profile with 720x480 resolution.

I hope it helps.

Regards.

Exactly, AVS assumes that the aspect ratio is the same as the resolution, which is wrong. Users should be able to specify a video's aspect ratio when it is added to the project.

Of course I can set the aspect ratio when I am going to encode the video, but then I can never see a proper preview while editing the project. Also if (for example) I add text while editing the project, the text will be stretched in the final video, when I encode it as 16:9.

In my opinion this is quite a design flaw.

AVS Video Editor set the same aspect ratio as resolution if entire video do not have info about aspect ration in the file. If it has, the program will put aspect ration from info of the file. In the new version of AVS Video Editor user is able to specify video's aspect ration when it is added to Timeline, please find the details here. Thus you will be able to see video on preview with desired aspect.
