Why does file size get bigger after.....

[Lee2003]

I got this program called MainConcept MPEG Encoder, to encode my AVI files so I can play them on my DVD player. I took Matrix Revoloutions which was a AVI at trhe file size of just over 700mb. After I encoded it it came out at overf 2 gig!!!, Why is this?? this means I have to split it into 4 parts? Can't it be any smaller

By the way I encoded it to SVCD are SVCD larger then VCD?

Why? everytime I stab somebody, I’m always gettin my clothes bloody, why?

Reason the size gets bigger is because the combined audio and video bitrates of the new encode are larger than that of the old and yes, SVCD's are generally larger than VCD's. VCD's are always 10MB's/min.

One bonus is that for (S)VCD the size of an 80min CDR is 800MB's and not 700, although you could remux the AVI and burn it mode2 form2 and still fit ~800MB's.

If you want smaller sizes then you have to lower the bitrate, problem is that MPEG2 is less efficient at low bitrates than MPEG4 which the AVI most likely uses, plus mp3 is more effecient than mp2. Also the AVI was mostly encoded from a DVD, which would be much better quality than itself.

nothing like making the new member feel welcome :saywhat:

Im from the old CDROM-Guide, Elaine sent me a mail to let me know you guys had moved to this one. So here I am, Very old member but new to these boards.

Anyhow, so I managed to split it to 3 parttsa then I went into Nero to burn it and it said it needed to encode it again because the file type was invalid. But if I use the file that came out unsplit it will burn but it can't because it's 2 gig. Is there any program I can buy/download that will do all this for me?.

try loading the orginal avi into TMPGENC (www.pegasys-inc.com) and spilitting it in to each part before you encode it, this will (if you use the wizard) make it compliant and then can burned with nero.

unfortunately ive never used main concept and dont know what output settings it has as standard.

if you dont want to re-encode im sure someone will help you pretty soon on here anyway, i just thought id add my method

ah, i see now, i'm sure it was meant in jest anyway.

how did you split it out of interest?

I split it into 3 parts 41 minutes each each with AVI,MPEG splitter. Loaded it into nero and Nero said it needed to encode it but I already encoded it before I split it. I will try splitting before encoding.

i dont think cutting before encoding will make a difference, from what you tell me i think the output settings were incorrect before you encoded.
have you used mainconcept for encoding to the same format before?

Nope, the output format was SVCD, I am going to try TMPEG but that looks a little complicated.

[Ogs]

it does have a wizard, just select format svcd pal/ntsc on the left hand side
open up ur avi in the browse part of source video (2/5 in wizard)

to cut you use "source range"(3/5) and select start/end frames

[Lee2003]

Right I got the source range sorted but before that what Aspect Range size do I choose?

[Lee2003]

Also how do I cut the video into 3 parts?

[celtic_druid]

With the source range setting. Could also use AVISynth to frameserve to MainConcept, splitting that way. Something like:

avisource("whatever.avi")
trim(0,45000)

avisource("whatever.avi")
trim(45001,90000)

Then just open each part and encode it.

If you selected SVCD in mainconcept then it should be compliant. Guess maybe there was a problem with splitting. Did you select the same standard (PAL/NTSC) in Nero as your source?

[Lee2003]

Yes, I encoded all files last time, they came out alright in SVCD but the picture looks all stretched, why would this be?

The Originol fille was widescreen but after I encoded it ther black lines dissapeared and it looked all stretched, how can I get it so it comes out wide screen? 16X9?
