I've shot 4k footage since 2014, and when mastering in 1080p, I often use digital zoom in post. There are multiple factors I would look at. Cameras that use a single sensor will display debeyering artefacts when examining the direct pixel readout (mushier detail and reduced colour information). This issue is nicely improved when downsampling 4k to 1080p, ...

I have that camera. Here are a few things to consider: The camera doesn't have any in-body stabilization, so the footage can be very shaky unless you're prepared. In my situation, I knew I wanted to use a gimbal to stabilize. This works great, but it will affect your lens choice. If you plan to use the BMPCC on a gimball ever, remember that you won't ...

pzoom is the calculated zoom value for the previous frame. It is initialized to 1 at the start of filtering. So, if total no. of frames is X, your zoom expr should be z='min(pzoom+(2.13-1)/X,2.13)'

For videography you do not necessarily look for "a good" lens for pixel peeping, you want a good autofocus system and a wide aperture for a "cinematic look". This depends on what type of videography you are doing. Interviews, documental, landscape, indoors, outdoors, using a tripod, using a handheld. Jason Conrad's answer is interesting because he is using ...

For most people, the first workhorse lens will be a zoom, because of the versatility. Sharpness in lenses isn't a huge factor for video; at HD resolution and below, lenses that photographers turn their noses up at for their sharpness do a perfectly adequate job. Once you're shooting 4k it starts being a bit more important, but even still that's way below ...

Use ffmpeg -i file.mp4 -i image.jpg -filter_complex "[1:v]pad=iw*2:ih*2:(ow-iw)/2:(oh-ih)/2:c=black@0,zoompan='1+on/125':x='(iw-iw/zoom)/2':y='(ih-ih/zoom)/2':d=125:s=WxH,format=gbrap,fade=t=in:d=5:alpha=true:st=0[im];[0:v][im] overlay=x=10:y=10:enable='between(t,0,5)'" out.mp4 The image is padded to double width and height with the padding colour being ...

There's a few ways to do this. The simplest is to make the castle layer the parent of the magnifying glass (use the parent drop-down or the pick whip), so that as you scale the castle up the magnifying glass scales up as well. This will let you move the magnifying glass independently, because child layers inherit the parent's transformation, but not vice-...
