The subtitles built into the video are off I think because a different framerate than the video.  They start out synced but within a minute or so they start getting behind and by the 7:30 mark the subtitles are about 15+ seconds behind.  Do I need to extract the subs, change their framerate, and then re-embed them?  That sounds really complicated.  I read about something called &quot;advance synchronization functionality&quot; but I can't seem to find that anywhere.  TIA

How to perfectly synchronize Subtitles with movie? i use VLC
122433
When I import same movie clip, recorded with my phone, in Blender 2.80 it automatically recognize 1278 frames with FPS 42.28 and that's correct, but blender 2.81 and above recognizes only 923. So when I render clip to frames I'm missing 355 frames although in sequencer when I slide through timeline, I can preview those frames. I tried to play with FPS and Base settings but with no luck. Does anyone know what's happening here? Thank You

I've rendered about 300 frames for a short clip. The frames look fine, but when I compile into a movie all I get is a black screen. I haven't been able to find anything to solve this problem. The individual frames are well lit, capture what I want them to, look great. Just creating the AVI or MPEG results in a clip that has nothing but black.

Let's say I only want a section of the timeline to be rendered, and I want the final output to be in RAW AVI format.  How would you do that? Thanks guys!

I have two high-quality mp4 files, which are of two parts of the same show.  I want to merge them together into 1 file, and I usually use VirtualDub to merge my files... But it doesn't seem to support mp4.  What alternatives are available (especially ones that don't require re-encoding)?

I absolutely hate it when I watch a video on YouTube and it automatically loads another video page after it's done playing.  This is especially annoying when I'm in the middle of typing a comment as it will cause me to lose what I have typed.  I'd like the video to simply stop and for no further action to take place once it is finished playing.  Is there any way to accomplish this?

This Super User answer  has got me so far, but now that I have tried many solutions and seen every SO link out there, it's time to ask you all for help.  I am trying to crossfade 2 videos that are 10 seconds each in ts format with audio and video at the same time.   The steps are:   Add complex filter black screen Fade out video 1 after 9 seconds, with 1 second fade duration Fade in video 2 at 9 seconds, with 1 second fade duration Trim black filter output to 19 seconds   This works fine for just video alone, but when I attempt to add audio, I can't get past this error message:     Output pad "default" with type audio of the filter instance "Parsed_asetpts_4" of asetpts not connected to any destination   It appears I'm not connecting the audio output properly. I think I need to alter the [over] lines to include audio. But how do I do this?  `ffmpeg -i vid1.ts -i vid2.ts -f lavfi -i color=black -filter_complex \ "[0:v]format=pix_fmts=yuva420p,\ fade=t=out:st=9:d=1:alpha=1,setpts=PTS-STARTPTS[v0];\ [0:a]\ afade=t=out:st=9:d=1,asetpts=PTS-STARTPTS[a0];\ [1:v]format=pix_fmts=yuva420p,\ fade=t=in:st=0:d=1:alpha=1,setpts=PTS-STARTPTS+9/TB[v1];\ [1:a]\ afade=t=in:st=0:d=1,asetpts=PTS-STARTPTS+9/TB[a1];\ [a0][a1]amix=inputs=2;\  [2:v]scale=720x406,trim=duration=19[over];\ [over][v0]overlay[over1];\ [over1][v1]overlay=format=yuv420[outv]" -vcodec libx264 -y -map [outv] final.ts`

Is there a way to let embedded videos (primarily Flash, but I'd prefer something that will also work with HTML5 video) automatically background load, but not start playing until explicitly started?  The typical use case where I want this ability is when opening a number of what I expected to be text pages in separate tabs using middle-clicks only to have something start yapping at me; at which point I need to click through all the new tabs to find and stop the offender.  I'd prefer not to completely block video download to avoid the startup delay if I decide to watch the video when I view the page its embedded in.

I already searched the internet but could not find a solution to this. Maybe it is the same question as  but there was no answer.  I want to render a video with tracking, but the output "loses" color information and gets kind of greyish. I first thought that it is related to the renderer, but it happens in Cycles and Eevee. Therefore i made a sample image, added it to the image sequence editor and rendered it as 1 frame. Resulting in the same problem.  I placed the original image beside blenders output so that you can see the difference. The only idea I came up with is that something with the lighting is not correct but I can't find a setting for that.  I am using Blender 2.80 with the default settings. Only set the output resolution to match the input resolution.

Got a bunch of .mp4 videos (info shows H.264 Video + AAC Audio) that are chapters of a larger video.  I'd like to merge them, but not sure which is the best way.  I don't have Quicktime Pro, but I'll get it if that's the best way to do this.  Edit: Just to clariify this is Mac OSX 10.6 I'm on.

I'm putting together a video from the VSE. In the sequencer window it is rendering and scrubbing at near realtime yet during output it is taking around 3x longer.   The frames are taking 0.13 seconds each whilst the CPU is only utilised around 20%. I am rendering onto an SSD and using H.264 format 1280x720. Tile size options etc appear to have no or very little effect.  In short - is there any method to speed up the rendering of frames from the VSE?

What are the benefits for viewers of subtitling over dubbing -or- dubbing over subtitling foreign TV and film?  I've noticed some media will opt for subtitles, while others will opt to dub.   There must be benefits and drawbacks to both, for example:   Reading vs. Listening:  Reading might be harder to put oneself in the scene, where as listening could make you feel a part of the "show".   Are there any studies or any data as to benefits and drawbacks of subtitling vs. dubbing?

When I import a video in blender, I get audio and video on two separate channels.  And beside the name displayed on the channel I get some number:  video name: path | number I am talking about  The numbers in both the audio and video channel, do they have to match? The guy in a youtube video tries to match them by changing fps, and they match for him. But I can't get them to match.   So, do they have to match? How can I do it? Would there be any problem if they don't?

I added tracks and stuff, but then when I tried to solve motion track, there was a error that said:     Some Data Failed to Reconstruct   and it also said to look into the console for details, which I did. This is what the console said:    By my understanding, my video is 372 frames long, and Blender is cutting the footage at 318 for some reason. Here is the image of the scene:    Why? Here are links to  and also . Also the next morning I did a camera solve, but then most of the frames went red.

After done editing, I exported only to see that audio and video do not sync. I know what the problem is - the project's video strips have a variable frame rate. But is there a way to make Blender sync them despite that? I don't want to encode every clip that I have with a CFR.

I want to create 5 second mp4 video from 1 image.  When I use below code the video is smooth. Default direction is zoom in to top left.  ffmpeg -loop 1 -i prop1.jpeg -vf "zoompan=z='min(zoom+0.0015,1.5)':d=125" -c:v libx264  -t 5 -s "800x450" fade.mp4   So, to zoom in to top right I figure it out to use the code below  ffmpeg -loop 1 -i prop1.jpeg -vf "zoompan=z='min(zoom+0.0015,1.5)':x='if(gte(zoom,1.5),x,x+1)':y='y':d=125" -c:v libx264  -t 5 -s "800x450" fade.mp4   It is zooming in to the right direction but the video become jittery.  Also got some error when converting :  [swscaler @ 0x429bda0] deprecated pixel format used, make sure you did set range correctly [swscaler @ 0x429bac0] deprecated pixel format used, make sure you did set range correctly [swscaler @ 0x429bac0] Warning: data is not aligned!
