Encode for Target Size Fixed!!

[Cauptain]

Hi all,

Anyone know any program other than RIPBOT264 (It seems to be the only one) that can encode using TARGET SIZE FIXED ??

I want 100mb give in 5Mb, 500Mb in 5MB, 1.2GB in 5MB, any size in 5MB (Example ok?).

You can also lcommand line too.

Anybody know?

Thanks,


Claudio

File size is proportional to bitrate:

file size = bitrate * running time

So any encoder that supports bitrate based encoding, essentially all of them, will work. Use a bitrate calculator if you can't do the math yourself.

Jagabo, the problem is that I need all to be the same size. No matter quality / resolution size. Just need to fit in 5MB.

I need to send for a special site and this is a limitation.

Try Handbreak / Vidcoder and nothing. Only RIPBOT264, but a i need other.

The formula doesn't contain quality or resolution. It's independent from that.

Try Handbreak / Vidcoder and nothing.

In VidCoder: encoding settings->"Video"->"Target Size" (2pass recommended)
Doesn't work?
Note that there is probably some limit to what's possible depending on video resolution, fps and duration. Also the audio format is important. AC3 640kbps will already take 4,5 MB for one minute for example.

The quality, frame size, frame rate, codec, etc. have nothing to do with it.

Vidcoder/Handbreak dont work. Try various settings. RIPBOT264 work.

Very strange.

Vidcoder/Handbreak dont work.

What does that mean? Error message? File too big? File too small? Post MediaInfo of input and output file if the target isn't hit.

Thank you all.

RIPBOT264 make job for few videos, other higher videos no (give me x264 [error]: requested bitrate is too low. estimated minimum is 21 kbps.)

No error at all, only exceed determined size stipulated for me.

You didn't answer my question about VidCoder but like I said: there's a limit to how small you can make your files. For very long and/or high resolution files you can try to reduce Framerate (fps) (in "video" tab) and resolution (in "filter" tab) but still - only so much you can do.

Note that the inaccurate file size doesn't mean the above equation is inaccurate. It means the encoder did not deliver the requested bitrate. That can happen if you specify too low a bitrate or too high a bitrate, or if you have placed other limitations on the encoder (min/max quantizers, # of keyframes, etc.).

Yes, I try this in both softwares. biggest size file.

Yes, I see and learn.

You didn't do what I said in post #7.

Yes mate, make it:

No.
