need help re encoding a video from my camcorder

[kaitlin4599]

ok so i bought a used samsung smx c10rn xaa camcorder off ebay and it works but theres a problem.when i record the videos in widescreen 16:9 it encodes the video with the black bars on the side of the video instead of on the top of the video if i record in 4:3 everything is fine, i did some research and found this is a known problem with this camcorder at least to other who use it. so far samsung tech support is worthless as there more clueless then i am heres the video encoding info i got from the manual

Video Format Standard Definition
MPEG AVC/H.264
720 x 480i / 60 fps

now since i have the latest firmware is there a program i can use to fix the video ones i upload it to my windows 7 pc, since i cant fix the issue witht he cameras encoding can i fix the video with software before i upload it to youtube

edit heres more info:

the videos do not end up encoded in the proper 16:9 widescreen ratio. This seems to be a problem with other lower end Samsung cameras (the MX-20 has the biggest complaints about this online) and if I would have known this ahead of time I would have stayed clear. The camera records the video in 720x480. This is widescreen and looks fine on the camera. The minute you plug it in to your TV or play the file on the computer you will notice the black bars on the side. The video is actually in 3:2 ratio!!! This is a bug in Samsungs encoding. Search for Samsung widescreen camcorder problem and you will find it.

edit#2 so what program would i use to re encode or reformat or even convert the video to proper 16:9 assuming i film in 16:9

the videos do not end up encoded in the proper 16:9 widescreen ratio.

They may not have to be. You said they look fine in the camera so I'm guessing there's a 16:9 flag that tells how it's to be displayed.

The video is actually in 3:2 ratio!!!

So what? Every 16:9 widescreen DVD you've watched has also been stored in that same 720x480 3:2 ratio. Maybe post a short 10 second sample from the camera.

The minute you plug it in to your TV or play the file on the computer you will notice the black bars on the side.

Maybe your players don't honor the flag. You could always convert it to DVD using AvsToDVD so your TV set and players will display it correctly.

Yep. It has wrong display aspect ratio. You can change the header in the mp4 to 16:9 using mp4box....it's a command line tool so it's not that simple:

Get mp4box, put mp4box.exe in same folder as your mp4. Then start the Command prompt and type

C:\VIDEOS\MP4Box -add "C:\VIDEOS\video.mp4#1:fps=60" -add "C:\VIDEOS\video.mp4#2:lang=en" -par "1=32:27" -new "C:\VIDEOS\newvideo.mp4"

(Change the directory C:\VIDEOS\ to your folder with the video and mp4box)

(Calculate the aspect ratio/ par value with http://tools.rodrigopolo.com/mp4box_aspect_fix/ . )

A quick fix is adding this tag to your video:

yt:stretch=16:9

A re-encode would do it too. Using VidCoder and setting the PAR to 64:54 would give you widescreen:


You could probably also set the AR to 16:9 for the file without re-encoding/losing quality. Someone else could recommend a program for that (as in post #4).

im not so tech savy is there a program i can use that isnt command line based? as i dont wanna have to use a command line for every video as i upload loads of videos every day id rather a gui based program if possible

Then mike20021969's suggestion is probably the best - while uploading to YouTube add the tag just as he shows it in his post. I've experimented with it before and it works:

Formatting tags

Tags are descriptive keywords you can add to your video to help people find your content. However, you can also add tags to change the appearance and format of your video on YouTube and on embedded players.

Examples of formatting tags

yt:quality=high: Defaults to a high quality stream (available based on the size of the viewer’s player and the size of the browser window)
yt:crop=16:9: Zooms in on the 16:9 area, removes windowboxing
yt:stretch=16:9: Fixes anamorphic content by scaling to 16:9
yt:stretch=4:3: Fixes 720x480 content that is the wrong aspect ratio by scaling to 4:3
yt:crop=off: Deactivates cropping effects on the video and reestablishes cropped areas

How to add tags:

While you’re uploading, you'll see a “Tags” section below the upload progress bar where you can add your tags.

To add tags to an existing video, visit your Video Manager, then click the Edit button below the video for which you'd like to add formatting tags.

The old Yamb...but I think it's even more complicated than mp4box from the command line.

Or I can write you a simple batch file for mp4box. You just to double click on a .bat file and it will fix all mp4 files in one step.

Or use the youtube tags....

but wont scailing it to 16:9 cause the video to look stretched and loose quality

[kaitlin4599]

batch woyld work perfect i just dont know how to make a bat file thingy

[Baldrick]

but wont scailing it to 16:9 cause the video to look stretched and loose quality

Nope.

[Baldrick]

I would try the youtube tags.

But I made a simple mp4box batch script. Download the attached file. Extra all files and folders. Put your mp4 files in the oldvideo folder. Double click on fixaspectratio.bat. Then check the fixedvideo folder.
