View Full Version : MKV to mp4 too much size deviation

Hi everyone,

Lately I started re-encoding my anime from mkv to mp4 to put on my server. (private) As I'm a n00b to encoding and don't know too much about it i'm in kind of a pickle. Everytime I encode, the size just skyrockets with the resultant mp4. The MKV files are all encoded in h.264 and have embedded soft subs. They are around 200 mb and this particular series is in 720p. I use videora xbox converter to re-encode them as it can encode batch video's and uses avisynth automatically so i don't have to make one myself. The problem is that the resultant files are like 400 mb at 480p in comparison to the 200 mb MKV file which is in 720p! I don't even want to begin what happens when i encode the video on 720p (the original size). It takes around an hour to encode and the size is humangous.

My settings for re-encoding at 480p are as follows:

I encode with ffmpeg 1 pass, main profile level 3, with 2048 ABR bitrate (which is enough and doesn't cause blocks at this size). It's at 720x402. I didn't play around in the Misc settings. The only thing enabled is CABAC and i have no clue what that is.

For 720p encoding i used basically the same setup only it was 720p (lol) with 15000 kbps ABR. Audio is AAC-LC at 160kbs

My question now is: How can i fix this... how can i basically burn in the soft subs to my videos without increasing the file size so much when in mp4. I would like to be able to do it in batches if possible.

I've looked around and found meGUI i'm experimenting with that right now. I don't know if i can get subs to work.

EDIT: The source IS mkv... I'm not an anime fansubber or anything, i just want them in mp4. Sorry if that was not clear :)

Why don't you re-encode from your original source material instead of the MKVs?

We can't help you as your content is obviously illegal.

ahum... downloading unlicensed anime is not illegal. Plus.. you might not care but i have the dvd for this particular anime. I thought it was subbed when i bought it but it wasn't hence the fansub download. Even then, who says that i do not own every single dvd of the anime i have on my pc? Who are you to make false assumptions. You can atleast ask.

I support the anime studios, i only download the unlicensed and when it's licensed i usually buy the dvd, unless the anime was crap.

ahum... downloading unlicensed anime is not illegal.But irregardless of the fact that its legality is a gray area and varies between countries, Doom9 chooses not to permit discussion of it.

You still miss the point that i have the dvd... do you want me to take a picture of it or what?

Anyway... i figured it out.

No, you're missing the point.

If you read the rules, it clearly says discussion of ANY illegally downloaded copyrighted content is forbidden. You can talk about your DVD but not the content you downloaded since, regardless of the fact that you own the original DVD, it is still illegal.

I do understand where you're coming from, but we can't help you with that.

If that's the case then i have no choice left...

I HAVE TO BRING DOWN T3H INTERNETZ! MUahahahaha! Jk..

Alright no problem ;)

But for some reason meGUI still has the Anime "function"... Isn't that a bit ironic ? Anyway..
