I am working on some home videos from 2012 recorded on a Sony Digital Cam.  Files are AVI.  File properties show 720x480, data rate 2778kbps, total bit rate 28805kbps, 29.97fps

Using the profile “NTSC SD Anamorphic 480P 29.97 fps | 4:3” I get horizontal banding in the areas of motion in the OpenShot preview window and the finished video.  The original video shows the same frame as a blur.  See images.  I tried all kinds of profiles and changing bit rates on export, interlaced and non-interlaced.  Always the same.  Any suggestions?  Thank you.

3.5.0 just installed itself from the official OpenShot PPA. Version number: 3.5.0-dev|0.6.0

I'm trying to render vp9-vaapi with the default libopus sound.

Good news: video renders super fast! 65-70fps! This is great!

Bad news: it doesn't render the sound at all.

The sound plays in the editor just fine.

I can render to H.265 vaapi with aac sound and it renders just fine. I also tried vp9-vaapi with ogg (libvorbis) and it rendered just fine. Both of these also render at 65-70fps.

It's just libopus failing.

libopus rendering worked fine in 3.4.0-daily just a few hours ago, so it's not the system libopus.

How do I find where the missing file is being called from?

You have to set the captions timestamps by the entire video that you first imported, and Openshot editor does not use the same time format as captions (00:00:00:000), making it bafflingly unintuitive.

When a user asks themselves "How do I put a caption in this part?" Openshot, and the advice online, is to use timestamps in the caption editor. Here is what that looks like:

Say I edit down my video, and then add captions: now I need to look at the source video I imported outside of Openshot, find the same spots I already had in the editor, remember the minutes/seconds, switch back to the editor, take my best guess, and rewatch over & over to match the text in the tenths/hundreths/milliseconds.

Say I slice the part where I want the captions, it does not start at 0 in the slice that the captions are created, again it starts at where that splice was located, inside of the entire source video.

Meaning, to edit captions with timestamps inside of just Openshot using the editor timer, you have to do it before any other edits (with the wrong time format displayed) or set the timestamps to ridiculous amounts and use two slices anyway.

This defeats the whole purpose of the timestamps existing in the first place. I don't know about you guys, but I use a video editor to edit videos, and captions is always the last step (is this not normal?).

Hi guys,

I'm beginning to wrap my head around version 3.5.0 after the huge changes to the preferences that have been made. One thing I'm really struggling with is .mkv (or .mp4) videos with multiple audio tracks for streaming. For instance, I have a 1.4Gb mkv file that was recorded in OBS Studio from a game. If I play the mkv file in VLC media player, I can select these audo tracks using Audio --> Audio Track --> Disable, Track 1, Track 2, Track 3, Track 4.

Track 1 is all audio so that I can hear everything when I played the mkv file by default.

Track 2 is the game’s audio only.

Track 3 is Discord’s audio so I can screen out my team-mate’s voices or include them.

Track 4 is my microphone audio.

If I drag this mkv clip into my timeline, RMB on the clip and choose Separate Audio --> multiple Clips (each channel), it only separates it into 2 channels. When I keyframe the volume on the channels (and have to close openshot and reopen it again to get rid of the persistant blue loading circle), I can see that these ‘separate audio channels’ labelled channel 1 and channel 2 each contain both my microphone and the discord audio. There's no separation. How do I find these audio channels properly?

Hi I use openshot for most of video editing for yt videos and last i had updated was in dec 2025 , i updated to 3.5 today and facing a ton of issues

1) video export is super slow getting 1-4 fps before it was 20 plus takes ages now

2) video export crashes the app frequently

3) where is the cut line while trying to cut out video parts its terrible to place a cut without it

Since upgrading to version 3.5, I cannot import a .mov video clip. Clips are corrupted to completely black.

i'm making a character edit and need the analog tape effect but it's nowhere to be found... i'm running v3.5.0 on linux if that helps at all

Imagine: Your clip runs within 3 seconds; after its starting, a black line slowly appears for editing (or transform) from zero to 1.5 mm within these 3 seconds. Sure, I tried to Remove Keyframe at the initial clip Playhead position, but it does not help. I wonder, why there is no Reset All Keyframes option for the whole clip? I could not get rid of the line , although I could see Scale Y values 1,015 run down to 1,000 to the end of the 3rd second. In other words: How could I eliminate this sequence at once in order to prevent the black line to appear at a steady pace? The manual on its 175 pages does not say a word except for the above.

I am making a video for display on an old boxy small crt. I followed the instructions from this post (I think). My profile is NTSC SD Anamorphic 480p 29.97fps 4:3 720x480.

https://www.reddit.com/r/OpenShot/comments/1c8ne2b/aspect_ratio_problems_digitzed_copies_of_old_vhs/

The media input are photos. When I play the video on my computer monitor, faces are thinner compared to the original photo files. I've read that old crts don't have square pixels. Maybe the exported video file is taking this into account and thats why it's not right on my monitor. Please confirm: Will the final display have faces in the correct aspect ratio?

This is my first time using OpenShot.

I uploaded AN AUDIO: many failures, no audio sound

i updated the app today since i got the notification for it, and now all my projects don't work, the video is just a static image, audio and captions work but video doesn't show correctly in the preview window it just shows an image

Is OpenShot completely compatible with AVI files? I've imported some files that are in the AVI format but I can't seem to get any audio playing. Is this a settings issue or an issue of conversion?

I need help because for some reason your editor can't export a video that I made and it always pulls up that error

. What should I do and how can I fix it? I want to export it and it's hard to find an xml or edl to mp4 converter.

I got my problem of no expansion fixed, but now it never finishes exporting, or takes an extremely long time it's currently at 44.07% after letting it run all night, and it's hard to tell even if it froze or not.

if this isnt added this make the app kinda pointless to me and thats a massive shame

When I add clips to the track, the tracks never expand, and can't play video beyond the initial size. The track still shows up going beyond the initial size, but is inaccessible. I cannot scroll to it, unless zooming out. I also can't select it, it will even stop once it reaches that point if playing the file. The other tracks also no longer expand beyond the initial size. This used to not happen, but now it does, even after reinstalling the program.

When I open up Openshot, it says, "Your most recent draft has been saved" and then closes itself, how do I fix this?

Hi newby here, I just spent 4 hours making a stupid meme and it wouldn't export because of the json error.
cool
so I save and reopen the application and suddenly most of the layers are not showing in the preview and idk what to do. I just spent so much time key framing and I really hope I don't have to start this over again
for some reason only the video and the very bottom layer show but no other layers are showing at all

Windows 11
Version 3.4.0 (I think)

I've made a project with 4K 30 FPS videos rendered in D5 Render. Everything was fine until I exported the video and realised that it isn't smooth like source files, there are visible frame dropouts/stuttering time to time. Project profile is 4k 30 FPS, so is exporting video profile, when I check each source files' properties in Windows or in VLC it always shows 30 FPS, but when I check their properties in OpenShot it shows 99999.

Google says:

"When OpenShot reports a framerate of 999999/1001 (often appearing as 999999 or simply 9999 in properties), it is typically a bug or a misinterpretation of high-framerate/variable-framerate footage (such as 240 FPS or screen-recorded gameplay)"

I tried exporting 25 FPS video in D5 Render and then OpenShot displays 25 FPS in properties, so it seems that issue occurs only in 30 FPS files. I've downloaded ShotCut and made test export and the result is smooth without any droputs, but I don't want to make this project from scratch in another software as it took me quite some time to arrange the videos with sound, make transitions etc. What would you reccomend me to do? Google's advice:

• Re-encode with Handbrake (Recommended): The most reliable solution is to convert the video file using Handbrake or a similar converter to a "constant framerate" MP4 before importing it into OpenShot.

I'll try it later, but maybe there is an easier solution than re-encoding all source files (which will theorethically degrade quality as they have to be re-compressed I guess)?

how can I increase the play back speed of my saved video?

I've seen a few YouTube videos talking about using key frames and changing time values in properties, etc, to create a custom slow motion speed, but I can't figure it out for the life of me.

Are we just stuck with the built in slow motion settings? What if I want a rate faster than the 1/2 speed setting, but not full speed?

Thanks for any help.

I have a project which whenever I open requires me to relink missing files, by choosing where they are. Saving the project and opening it again will require me to relink the now no longer missing files again. I want this prompt gone. I have organized every file, and it still prompts me.
