The lower left pixel would be 50 transparent Black. vf 'crop:in_w:in_h-2' //minus 2 pixels from the original height of the picture Try to apply a filter that first cut original video height, so the height was divided by 4 without a remainder. Take the height 178 is 180 and black stripes 62px (31x2) Otherwise, it will just add 60 pixels to bottom. calculates the height of the black bars added to the video 240-180=60 (30/2) Leave the X offset at 0 & set Y offset to -30 so pixels are added at top & bottom. since you mentioned that you want to crop on the input, your probably want to change the order of your video filter options. so the crop command would be: Code: cropw1920:h808:x0:y132.

1280/320=4, hence the height of the picture is 714/4=178,5 ~= 179 plus rounding up to the nearest even, as the height put 180Ģ. Use a rectangle with the full width (1920) and a limited height (1080 -132 -140) and place it at x/y-coordinate 0/132 (0/0 is the upper left corner). Did the calculation of the proportions of the thumbnail image starting from the original width, i.e. You need to get the output file with 320x240 resolution, preferably without cutting, and adding black bars.ġ.

Use the slowest that you have patience for. A slower preset provides better compression (quality per file size) but is slower.

-tune zerolatency Optimization for fast encoding and low latency streaming.

-tune fastdecode Disables CABAC and the in-loop deblocking filter to allow for faster decoding on devices with lower computational power. widescreen using ffmpeg, maximizing size, with no black padding.

Here, the grain won't be filtered out as much.

-tune grain This should be used for material that is already grainy.Use minterpolate videofilter to interpolate images and make a smoother video. Select the orientation, resolution or scale, and refresh rate.
