View Full Version : Keep aspect ratio?

I'm using CCE for the first time, v2.70. I normally use TMPGEnc but I'd thought I'd give this one a try.

In TMPG you can select 'full screen, keep aspect ratio' but I can't see an option for this in CCE. Only 4:3 or 16:9. It doesn't give the same results as in TMPG. The picture is in the centre of the screen with huge subs underneath rather than near the bottom of the picture. How do you do it?

My personal opinion on TMPGEnc vs CCE: MPEG-1, continue using TMPGEnc; MPEG-2, use CCE (multipass VBR). TMPGEnc does audio better than CCE. TMPGEnc also allows 'toolame' as external audio encoder, thus getting 'best' audio.

Answering your post:
Consider this as just one drawback of CCE, no arbitrary manipulation of frame size & speed during encoding. As a result, it does its work at a blinding speed. So, in CCE, you get yr MPEGs exactly as your source - frame size and fps.

Most of us wld 'do this outside' CCE. Avisynth is an 'almost' mandatory companion for CCE. Write a simple Avisynth script that'll do the necessary resizing for you - 'BiCubicResize()'. Then, pass this script to CCE to read as video source. Here, I'd like to mention that Avisynth also allows you to do a lot more important things as you get to grips with CCE in the longer run.

Aspect Ratio guessing game: I usually 'ask' TMPGEnc to guess what the source aspect ratio is and what to do to get the output aspect ratio, for eg, when I crop my source. Once I got everything fr TMPGEnc, I'll incorporate all these into my Avisynth script - crop+resize, etc. Dead simple.

At first glance, Avisynth may scare you. But just concentrate on the 'BiCubicResize()' function for the time being - this gets you switching from TMPGEnc to CCE quickly. So, your Avisynth script may be as simple as:

#avisynth
AVISource("your_source.avi", audio=false)
BiCubicResize(720,480)
ConvertToYUY2()


Just 4 lines of 'code' and you'll only change the 'your_source.avi' parameter when encoding other AVI files.

HTH.

I did notice the speed difference. CCE did the movie in 30mins rather than 2hours in TMPG. Now I understand why. I do use toolame as an external auido encoder. That's the way I've always done it.

Thanks for the reply, I've heard of avisynth as but never used it as it seemed complicated. I'll look into it.
