Hello, I am a beginning user of Shotcut and had a question regarding the video mode.
I am putting together a lengthy video (a virtual piano recital featuring 20+ students) combining several different videos taken by multiple people with different resolutions and frame rates. When creating a new project and setting the video mode, which resolution and frame rate should I choose? The resolutions range from 720p to 1200p and the frame rates range from 29 to 60.
Also, I am creating the video to be shared via Youtube premiere. Should I just use the Youtube preset or adjust the export settings? Thanks in advanced!
Talking about the resolution, you could use 1920x1080, 1280x720, or the resolution that your videos have in the majority.
Retaining most video quality in YouTube
If you export a video in 4K then YouTube will use better processing and codecs to retain the most quality even if the video was 720p and exported in 4K.
Talking about the framerate, you would choose the framerate in most of your videos or the framerate that is the average of all your videos.
Choosing right framerate
Framerate has a very big impact on the speed of your videos, sometimes it is very helpful for advanced users, but sometimes beginner users have big problems because of wrong framerates. For example, if you have a 240fps video and export it in 24fps then it will make the video 10 times slower, and if you have a 30fps video and export in 60fps, it will make your video 2 times faster. So you need to choose the average framerate of all of your videos or the framerate that is in majority.
Correction:- This only happens if the user changes Properties > Speed to be 0.1x speed. Otherwise, if a user drops 240fps video on a 24fps timeline, Shotcut will throw away 216 frames per second and only display 24 of the 240 (every tenth frame) to keep the pace of time constant. The same thing happens if a 240fps timeline is exported as 24fps. There will not be any perceived slowdown. This is called the âframe droppingâ mode and it explains why video has stutter or judder when people mix up frame rates⌠a bunch of motion (seen in extra frames) got thrown away or duplicated depending on the type of mismatch.
You could choose the YouTube preset if it gives you good results, but I advise you to set all the settings yourself to get the best results.
Getting the best quality
Choosing 4K will give you better processing to retain more quality in YouTube, choose the quality percentage lower than 68% because the human eye canât see higher quality than 68% most of the time.
videos from many simple devices/smartphones e.g. can also have variable frame rates (vfr) and have to be converted to fixed fr in SC to really work and be editable.
Try to find out the video quality from each clip and try to combine the best ones which are more or less compbatible. I would aim at best YT-quality but not overdue the resolution as most people would view in best case in full hd, 1920x1080 resolution. Also 720p would do in most cases.
If you combine different FR you can end up with flickering in fast motions. If its a piano concert its probably not very likely unless there are great camera movements. You can simply cut out these scenes if necessary or replace the video by a picture e.g. - let the audio run without interruption.
I would aim at a FR of 30 fps - that fits great to computer monitors which mostly run at 60 Hz (25 or 50 fps results in flickering at 60Hz monitors).
Thank you for the replys. Most of the videos are taken with smartphones on various phones and settings.
To give you a better idea, this is very much like what I am trying to make.
Iâm assuming the videos in that video are also taken with smartphones with different settings, but it seems pretty good to me. Unfortunately, I wonât be able to edit their videos when flickering happens. They have to be presented as a whole without editing. I want to make sure I maintain a good video quality with unaltered speed of the video. Having a video playing slower or faster due to frame rate issue wouldnât be good.

Okay, thatâs exactly what I needed to know. Itâs good to know that although the quality might reduce slightly due to the âframe droppingâ, at least the videos will play at or very close to their true speed and the adjustments will happen automatically. I guess I will set it at 1080p and 30fps, since those are the most frequent settings. Thank you for the reply!
Blender will do the same thing as Vegas⌠it uses every frame of the input video even if that would cause a time drift with a timeline thatâs in a different frame rate. Itâs incredibly annoying to documentary filmmakers that receive footage in a variety of formats, because all clips must be pre-processed to the same frame rate before importing into Blender/Vegas, which can cause a generation of loss before even getting started. I love that Shotcut does the rate change automatically.
What is it youâre trying to do? There is the standard âselect clip > Properties panel > Speed = 0.1xâ if a clip needs to be 10x slower. Usually, the common editing scenario is to keep time constant, so Iâm curious what process youâre doing that Shotcutâs default behavior is inconvenient.
. But now It is working Fine.
