Lower framerate but higher quality

[sakishrist]

Hi there!

I have a low quality video that was shot by a webcam at night and there is not much motion in it since the camera was stationary.

My goal is to lower the framerate but get higher quality in each frame. My guess is that if there is an encoder that could mix several frames into one that would solve my problem.

The problem is I could not find any such encoder.

Thanks for your help

Lowering the framerate wouldn't make the slightest difference in quality. Any reencoding will make it worse.

There are some things (like avisynth filters) that may make it more tolerable to watch, if not 'better'. But those things aren't simple to use.

It would help if you provided a sample.

The x264 encoder is actually frame rate aware..... encode a video at 24fps, then re-encode it again at 25fps, and the file sizes will be a little different even when using the same encoder settings and CRF value.

If there's very little motion then you're probably better off deleting frames rather than trying to merge them. What's the current frame rate and what frame rate do you want to end up with? AVISynth offers a few different methods for changing the frame rate if you're familiar with using it (http://avisynth.org/mediawiki/ChangeFPS), but I'm sure there's a few free encoders which make it fairly easy to select a new frame rate. AnyVideoConverter comes to mind. I'm pretty sure it blends frames where necessary in order to convert the frame rate but I haven't experimented with it much in that regard. If you halve the frame rate chances are it'll just drop every second frame, but I don't know for sure.
