video becomes huge after cropping

Post by kaz219 »

Hello,

I apologize if that's not the right forum for this. Please redirect me if that's the case.

My problem: I have an mp4 video with black bars that I want to remove. The cropping works, no problem, but the resulting file is then three times bigger. The video is a presentation with very little animations and audio. The original file is 12MB and the cropped file is then 40MB.

When opening the original video with mPlayerX and getting infos, it says: H264, 12.6kbps, 1024×768, 8.0fps MP4A, 18.0kbps, 8.0kHz 32bit, 1 channels.
After cropping, everything is the same (including fps) except for the kbps for video, which is then 76.6kbps. (I use passthru audio)

Any tips or ideas what the issue might be?

Sorry about that, that was written in big red letters on top and I missed it.

Re: video becomes huge after cropping

Post by JohnAStebbins »

I think that your source video must be very low quality

Code: Select all

    Stream #0.1(eng): Video: h264 (Baseline), yuv420p, 1024x768, 12 kb/s, 8 fps, 8 tbr, 90k tbn
12 kb/s is a very low bitrate, even for 8fps video. If you want something comparable in quality, try raising the RF value on the video tab to 32.

Encode for lower quality (higher RF) and tune for still images.

I tried to tune for “stillimage”: 36,197,110 bytes instead of 33,269,648 bytes for video. So it's worse.

You conveniently ignored part of mduell's suggestion :P

So you should have followed John's advice (use RF ~32), not just the tune with RF 20:

If you didn't need to crop, the best advice would be "don't re-encode the video". But since you do need to, your case is one where two-pass average bitrate (with a target bitrate close to that of your source, say, 15 or 20 Kbps) could make sense.

If you have the time, I suggest you try with and without the stillimage tune (at the same bitrate) and compare visually. Chances are the stillimage version will look better, but since it does use very strong psychovisual optimizations, you never know.

Of course, re-encoding to such a low bitrate may cause a perceptible loss in quality, but the only way around it would be to accept that you need the output to be larger than the source in order to maintain quality (the only way to get the same or better quality at the same bitrate would be to go back to the original master recording used to create the video you're currently trying to re-encode)…
