AVI madness

[gilbates]

guys i`m real green but trying hard to learn , but just cant get to grips with getting an AVI file to a vcd

i have read loads here and downloaded and installed a host of stuff but i`m not winning

i have an AVI file 700Mb downloaded from the net which is a fantastic quality copy of a film and i want to put it on a vcd

i have tried encoding it with virtual dub using the 5.1 divx codec and lame3 audio compression and again with the same software using fast motion codec and have got an output AVI file of a smaller size , around 400 Mb

but when i try to create a VCD with Nero it wont fit on the cd , it encodes it again and is too large to fit on one cd

so i have used a bitrate calc and input the film length and changed tmpeng settings to match ( audio and video settings ) and ran the 5.1 encoded version of the film through that but it spat out the same film 4 times bigger at 1.9Gb

i`m going mad here , i know i should be able to get a 700 Mb avi squashed down and installed on a single vcd but just cant get it done

Help please

Nero won't burn the file as a vcd because it does not meet vcd specifications. Look on the left under "what is" for vcd. Nero will encode your avi to meet the proper specs which will then swell the file size. If your standalone doesn't support avi, you are wasting your time trying to burn it to a cd as an avi file. Unless you want to watch it on your computer of course.

What a lot of people don't seem to understand about digital video is that the formats are all different in terms of file size.

For instance a VCD is MPEG-1 compression but your AVI is MPEG-4

MPEG-1 requires more bitrate than MPEG-4 to achieve the same level of quality. The higher the bitrate the larger the file size.

Also when you create a VCD you should stick to the spec which means you use a CBR of 1150kbps for the video and 224kbps MP2 audio.

With those values you can only fit 80 minutes on a standard 80min 700MB CD-R disc.

And here is the magic formlula ... the bitrate you use along with the original running time of the video being converted is what determines the final size ... not the file size of the original video you are converting.

This is what you are not understanding and why you think the VCD should be a smaller file size than reality allows.

Use TMPGEnc to encode your AVI file to a VCD compliant mpeg. Use a VCD template to ensure your file is VCD compliant. You can then use Nero to author and burn your VCD. Dont use Nero to encode the file you will get much better results with TMPGEnc.

...and split the AVI into two then encode and put it on two VCD's (so you could have ~160 min available on two CD's, and most movies are 90 - 125 minutes so it's no problem to fit on two). That should solve your problem.

Thanks peeps

will do as ya say and drop onto 2 cd`s

my dilema will be over after the holidays , getting a dvd writer , hopefully the pioneer

or make a 1 disc template for TMPGenc and fit up to 2 hours onto 1 disc with good quality, not standard compliant but most dvd players will play them

ok what you have is a mpeg video all you need to do is use video cd in nero to burn on cdr. let it analyse and then burn simple as that. if its under 700 mbs use this method should work

If you read again this person asking for help on converting an MPEG-4 AVI file to MPEG-1 VCD format.

I don't think you read very carefully :P
