Could someone please tell me how to turn these 2.35:1 mpeg4s into a 16:9 without any squishing?

This is a very common question on video forums.

You have to either trim off of the ends in your editor or squish the video Or live with the black bars.

Since I want to see all of the movie I live with the black bars.
This is because 16:9( like a HDTV is 1.77:1, so to fill the screen you have to lose the difference between that and 2.35:1.
do the black bars on the sides of 4:3 video bother you?

Bottom line you can put it through a editor and trim it, losing some quality in the process as well as part of the video. or if you TV set has a Zoom function you can try that.

Found this one: http://en.wikipedia.org/wiki/16:9
There is a image partway down on the right side that shows the various aspect ratios as compared to a HDTV.

Good Luck
Roger

I think black bars is the way to go.
I use Mpeg Streamclip on my Mac to insert black bars on video when I don't want to stretch it. I works very well, fast, and does a decent job encoding without artifacts. Keeps the audio/video sync as well.

http://download.cnet.com/MPEG-Streamclip/3000-2194_4-10496369.html

Import video, choose export to whatever, I use DV, in the DV (or mpeg4) exporter, find "Zoom" and "x/y" change them to whatever, to keep the original size of the video, (or closest) You may have to experiment with it. You can preview the video. You can also set your changes as a preset for future conversions.

you may also need Quicktime.

I know there is a Windows version, but I have never use it on windows. And can't vouch for it. The reviews are mixed. But it's free, with no spyware, or adware.


Also, Avidemux will insert black bars in video. "video" > "Filters" > "Black borders"
But it's tricky, you'll need to find a guide, maybe at, either at Videohelp, or Doom9
forums. It's not for everyone.

I never tried it with mpeg 4, though. Again, you'll have to experiment with it.

Good luck.
Mark

Kbit, do a test,

Take this test pattern and convert it to widescreen
http://www.dailymotion.com/video/x1l1vb_early-tv-test-pattern_shortfilms

When you are done compare, it has to either be cropped or stretched side to side. The circles will show any stretching, and a comparison to the original will show cropping.
