Add -video_track_timescale X to manually set a timescale of X. ffmpeg -i org_video_1280x720.mp4 -strict -2 -vf "scale=640:360" -video_track_timescale 90k new_video_640x360.mp4

The tape also operates at a different speed. It was more then speed than anything else. DVCAM still ised the 4:1:1 25mbit video format that DV used, but used a faster tape speed which allows for guard bands between the tracks which greatly improves interchangability between machines. Many DV decks will playback a DVCAM tape no problem. Decks like the ...

You can use ffmpeg's blackdetect for that: Let's say you are interested in blackscreen with a duration greater than 2 seconds (d=2): ffmpeg -i "surveillance.mp4" -vf "blackdetect=d=2:pix_th=0.00" -an -f null - output (example): [blackdetect @ 0x7fac3b555380] black_start:40 black_end:53.44 black_duration:13.44

FIGURED IT OUT THX TO THIS POST I FOUND ON ANOTHER FORUM PEOPLE!! "Find the main movie .m2ts file (could be 00001.m2ts) and find the matching playlist file in the PLAYLIST folder (would be 00001.mpls). Add only the playlist file in tsMuxeR and the matching .m2ts file will be imported. Go to the Blu-ray tab at top of tsMuxeR and select "Custom ...

Yes, that is subtle but nice. I am not sure how you did the image. If it is a raster image I would duplicate and add a gaussian blur on it and add transparency. You could play with the transparency to make some zones sharper

Looks to me like a kind of "chromatic aberration" effect - where the red green and blue channels of an image are processed separately - sometimes shifted in position or blurred a little, then they are recombined back together. There are lots of ways to do this using built in plugins, or using 3rd party plugins such as Red Giant's.

For live event video display, I would search for "VJ software." Because (a) I'm a video editor who uses DaVinci Resolve in his daily life and (b) I sometimes make typos when performing internet searches, I've stumbled across a piece of software called "Resolume," which appears to be highly regarded in this space, although I cannot ...

Theoretically it IS possible, and there are working, practical, proof-of-concept research on the subject. A couple of examples: Learning to Extract Flawless Slow Motion from Blurry Videos Blurry Video Frame Interpolation The picture below is from the second paper. However, as of this writing, I couldn't find any feasible-to-use, (commercial or otherwise) ...

Synchronizing the clips and creating a picture in picture effect are really two separate issues, and you could take many approaches to each. But basically, you drop one clip on one video track, and the other on a different video track. You synchronize one to the other by dragging either clip left or right on the timeline until they match temporally. There ...

There are dozens of ways to get that kind of colour shift. The way I would do it is by using colour/response curves, and perhaps hue / saturation controls. Most compositing, grading and editing software have these effects. Here's a two minute attempt in AE, trying to match the leftmost panel to the 2nd from the right. It needs work, but I got bored. Looks ...

Thanks to Gyan's answer! Taking that plus a bit research, I have applied it to speed up a video with audio by 6 times. Be aware that atempo argument has a value ranging between 0.5 and 2. So three atempo were used to make up 6 (2 x 2 x 1.5). So the idea is to make the video from 00:00:00 to 00:17:30, a total of 1050 seconds, to play 6 times faster and the ...

I've been running some tests lately (2H2020) concerning reducing the size of some high quality movies of my collection, just for PC to TV 1080p viewing, from 20-30mbps videos to 2-3mbps ones. To that end, I run some ffmpeg (latest gyan.dev version at the time) tests comparing same-bitrate encodes between: codecs (x264,x265,VP9,AV1), presets (slow, slower etc)...

In theory you could take screenshots and stitch them together. Any photo editor that has a panorama stitching feature can do this. The question is how sharp are those individual screenshots? It may be necessary to go frame by frame to find the sharpest.

Hmm. Perhaps I asked for help too soon? After more online searching, I found an Oiiwak Endoscope (https://smile.amazon.com/gp/product/B08L65982N/ref=ask_ql_qh_dp_hza) that claims 5cm to infinity for focal distance. We'll see if that's a legit capability or just a marketing claim. Anyway, I'm going to try it out. (The product info also states that it can ...

Have you tried using the ffmpeg playlist feature dubbed concatenate? The fade to black with ffmpeg has been described here.

The only solution I found is to open a new project on premiere, go to "edit", preferences, general and uncheck "show system compatibility issues at startup". This will make that thing desappear, but it won't fix any issue. Anyway, i hope it helps. Bye! Bizzarra
