Change the aspect ratio of an m2v MPEG2 file?

[theDruid]

Hi all,

I've done something really stupid - I set up a batch of files for TMPGEnc Plus to work on over night, creating half-D1 MPEG2 m2v files for me to use authoring a DVD.

It seems to have worked fine on all 6 files - but I forgot to change the aspect ratio in TMPGEnc to 4:3 - the sources are AVI's and I accidentally left the (output) aspect ratio as 1:1.

So, when I play the files back they are all very tall and narrow, and I am not conviced I can use them as they are to author my DVD.

Is there any way I can change the aspect ratio without going back to the start and re-encoding all of these files? I am hoping that the aspect ratio is just in the header of these m2v files, and that I can edit just that... but maybe this is wishful thinking!

I have searched for info on this, but not come up with anything useful.

Any help appreciated!

thanks.
theDruid.

Have a look at Restream https://www.videohelp.com/tools?tool=Restream

it might help

Changing the header info with Restream will do, no need to re-encode

Thanks guys!!

It looks like ReStream was exactly what I needed - I've changed the aspect ratio on the first file, and it now looks perfect.

I came pretty close to deleting all these files thinking I'd have to run the whole batch again; I'm glad I didn't now!

Thanks again for your quick responses.

cheers,

Hi; is there a program like ReStream which works with multiplexed mepg2 files? I'm trying to change the aspect ratio from 4:3 to 16:9 on some videos I have, without much success... Any help?

Thanks in advance
