![]() ![]() If you choose to work with the full-res version, the comparison clip will be 3840x1080 48 fps. The two 854x480 30fps clips, when combined, become 1708x480 30fps. I find it difficult judging the effect of an adjustment without a comparison to the unprocessed clip. It's included in Zeranoe's Windows builds: Not all builds of FFMPEG include the vid.stab library. Youtube-dl -f135+249 Ih3jg3Xdcvs -ignore-config -o shaky_480p To d/l the 480p version with audio and rename it while ignoring any FFMPEG output template file you might have already have set up: ![]() I used this for most of the testing, but the big size takes longer to process each time you change something.įor quick IS comparisons, the 480p30 works well enough. This will d/l the highest resolution version which is 1080p48 (130MB). Youtube-dl Ih3jg3Xdcvs (You can use the full YouTube URL if you want, but it's not needed.) You can d/l this clip using youtube-dl.exe ( ): "What is "no-chilling" home brew?" (3m33s) First off, here's a purposely jerky (sped-up) YT clip that irritated me enough to get interested in applying software IS: ![]() of 15, the program automatically alters the stepsize to 6 (and the comments in the source code suggest that a stepsize of 4 may be more suitable).Īnyway, I'll post a couple of comparison examples and a FFMPEG stabilisation testbench. If you use a high accuracy setting between 10 and the max. A smaller stepsize is more accurate.Īlso there was an undocumented change in the way stepsize interacts with accuracy. The function of the "stepsize" parameter described in is wrong. Unfortunately, vid.stab came from the linux world so some of the documentation is scanty, out of date (vid.stab was part of Transcode,, but it was later added to FFMPEG), or not very helpful for Windows users. I believe the performance of FFMPEG's vid.stab, in 2-pass mode, is superior to Vdub's deshaker plugin. (Specifically, see Mode 2 in Part 3's stab_testbench.bat.): But I've done a side-by-side comparison of original vs processed clips (processed using FFMPEG's Image Stabiliser filter vid.stab). ![]()
