Variable Aspect Ratio

[ATearing]

Hi i'm new to the forum, i joined because i've spent 5 or more hours trying to burn subtitles on a video and then burning it onto a dvd, when i thought i actually managed to do it i realized that the aspect ratio of the video was supposed to change ehile after burning the subs on it with HandBrake it kept still, cutting off very large bits of the image.

To. ake it clearer i'll post a video showing a similar case: https://www.youtube.com/watch?v=PoFM4pWCAg0 here at 1:51 the guy stretches the image, how can i put a similar video in HandBrake without losing both of the aspect ratios? thank you for your time and forgive me for my poor english i'm italian

Handbrake has auto-cropping which removes any black bars. Normally the size of the black bars doesn't change, so you'd remove them and encode the remaining picture. I assume what's happening is the size of the picture is increasing at some stage, which means the size of the black bars decreases, but Handbrake doesn't know and continues cropping the same amount, removing parts of the picture.

The total aspect ratio never changes. Black bars plus picture might have a combined resolution/aspect ratio of 16:9 (for example), and that over-all aspect ratio will stay 16:9. It's just the ratio of black bars and picture that changes.

The simplest solution would be to disable Handbrake's auto-cropping (I think you have to set cropping to "custom") and change the four cropping values to zero. That'll prevent Handbrake from removing anything.... the black bars will be encoded with the rest of the video..... but when the size of the picture increases as the size of the black bars are reduced, Handbrake won't end up cutting off any of the picture.

<3 <3 <3 <3 i'll try that immediately thank you

these are th epicture settings, crop is already set to 0

You need to pillarbox the "narrow" part of the video to match the width of the wide part. I don't think you can do that with Handbrake. You'll need an editor.

sorry not being english didn't let me understand your message can you be say it in a more simple way?

Is it likely the aspect ratio or resolution would change in the middle of the video somewhere?

ATearing,
What's the source you're encoding. I ask because a resolution of 720x720 seems a little unusual to me. I don't use Handbrake myself so I don't know if it's displaying 720x720 as it's really the source resolution or because you set that width and height yourself?

If the aspect ratio does change, I don't think you can encode it correctly with Handbrake.
If jagabo is correct, you'd have to do the opposite of what I thought originally, and instead of preventing Handbrake from cropping the black bars from the first part, you'd have to add them instead so the combined black bars and picture are the same aspect ratio as the second part. That way the whole video has a single aspect ratio, only the first part has black bars. Unfortunately though, you can't add black bars with Handbrake.

He did nothing. The video from beginning to end was 1920x1080. It's just that for part of it there were black bars on the left and right sides.

As jagabo said, make your video the same size all the way through, with black bars on left and right during the times when the video is more narrow, removing them when it becomes widescreen. Handbrake is useless for this.

Besides, didn't you say you're making a DVD? If so, you don't want to use Handbrake as an intermediate encoder.

oh ok i understood now, it was what i was afraid of, i think i'll just try to put the bars in After Effect would be that allright?

@manono i need Handbrake to burn subtitles on it

No, you don't. If you're making a DVD you make selectable subtitles like normal people. AvsToDVD is one such program that can take your subs and add them to the DVD you create.

If you're doing something else, many encoding programs have the ability to burn subs into the video.

i'm trying to edit the video i linked before, the one of the guy stretching the image

i'm using Mac, i tried several programs but i couldn't burn a dvd with optional subs

[manono]

i'm using Mac...

Then you're crippled from the start. You should have mentioned this in the beginning and you should have posted this in the Mac Forum. Me, I don't, and would never, own a Mac but even I can search for a solution. Try DVDStyler.

http://www.dvdstyler.org/en/

add multiple subtitle and audio tracks

[videobruger]

DVDStyler let you make optional (selectable) subs

i need Handbrake to burn subtitles on it

but should you want them hardcoded you can use a video filter in DVDStyler



If your subtitles are .ass replace the "subtitles" filter in the above with "ass"
