TMPGEnc Plus encoding quesion

[TripACT]

Hi again :P

I have another question related to TMPGEnc Plus.

What would be the best settings to work with if i take any divx movie (350MB approx) and encode it to .m2v format and want it to be no more than 1GB but not less as well than 1GB? How can i do it efficiently ? Is it possible? i know there's CBR encoding method but i didnt manage to get it right... When i want the resulted .m2v to be 1GB, i mean no matter how long the divx movie is originally, i want the m2v = 1GB at the end..

Is it possible? Is there an easy way to do that without messy calculations ?

Anyway thanks in advanced,
Gary

Your gonna need to calculate it. It doesnt go by file size but length in time. Use videohelps calculator https://www.videohelp.com/calc.htm or here is one I use often http://dvd-hq.info/Calculator.html?PHPSESSID=72e0c7bb5c6e110ebd86af36a41c99ab)

TripACT,

Vide encoding is all about numbers - resolution, bitrate, aspect ratios, file size, no of channels, lenght of video etc etc ... So where there are numbers there can be messy calculations

Another way is trial & error, which is not always advisable in the world of video encoding simply because its time consuming.

1. Encode you movie for one minute at a particular bitrate.
2. See the fle size.
3. Multiply it with duration of video in minutes. That will give you the final file size.
4. Is it what you desire. Increase or decrease the bitrate.
5. Go to 1

Whew! Repeat till satisfied. Good Luck.

Use Rejig after encodes

sanjayk, that works perfectly, in theory...in practice...well......it can have some problems, particularly if your using VBR for your conversions.....dark areas compress better, light areas don't generally compress as well, the amount of motion in the video, ect....all that stuff factors in to it..........if you want to use CBR though, that will work, another method would be to do a compressability test on the video and see how well it does in fact compress/decompress....there's also things to factor in, such as framerate...if it's only a 15fps video, there's no real reason to crank it up to 29.97fps or something like that, it will literally nearly double the filesize for no reason.............i guess just keep testing......sanjayk's method will probably get you at least realatively close.....

Enter the running time and desired file size, it tells you the bitrate.

jagabo,

after i get the bitrate where in TMPGEnc am i gonna put it?
should i use CBR in that case?

Here it is, as highlighted.

Great tool...

Thanks alot
