Always Out Of Sync

[Spottedfeather]

I don't know what's going on, but I have a video I'm trying to lower the size of...which I know how to do. But there's a problem. No matter what I do, when I lower the size of the video, the audio is out of sync. I checked the original video and the sound is perfectly fine.

I did a quick re-encode with ffmpeg and the audio was still in sync.

ffmpeg -y -benchmark -init_hw_device qsv=hw -filter_hw_device hw -v verbose ^
    -i %1 ^
    -vf "scale=720:-4:flags=spline,hqdn3d=1.0:1.0:1.0:1.0" ^
    -c:v libx264 -preset veryfast -crf 23 -g 50 ^
    -profile:v high -level:v 4.2 -g 50 -colorspace bt709 -color_range tv ^
    -acodec copy ^
    "%~dpn1.avc.mkv"

what is that code for ?

[Sharc]

Downscale, denoise and re-encode the video + keeping the original audio, and outputting the result as .mkv, by means of ffmpeg (commandline tool).

I'd just have to convert it to mp4...which is where the problem comes from. Plus, I've never used ffmpeg before.

To get mp4 instead of mkv all you have to do is change the "mkv" at the end of the command line to "mp4".

I don't know how to do the command line stuff, though.

[jagabo]

There are many GUI front ends for ffmpeg. Use one of those.

that's not a lot of help if I can't tell it what file to mess with. Why didn't you tell me how to do that part ?

[Spottedfeather]

Can someone who ISN'T rude please help me ? A person tried to "help" but just sent me a bunch of gibberish but refused to tell me what to do with it. He said it was command line but decided not to explain how to use the nonsense he posted.

I was not trolling at all.
jagabo had already given you a good answer.
Many newbies don't get what they want because they use bad software, usually commercial cr@ppy software.
OR because they use the right application in a wrong way, go figure.

But be welcome to my Ignore List.

He didn't give me a good answer. He just gave me a long text block but didn't tell me what to do with it. Like I should know. If I knew what to do, I wouldn't be asking, would I ? I invite you to apply your lips to my butt, troll.

[Spottedfeather]

Can ANYONE here help me ? No trolling answers like the ones already given. If you want to give me a block of text but actually tell me what to do with it, I welcome your assistance. Not a lot of helpful people here.

create a new text file on the desktop and call it ffmpeg.txt.
Open it and copy in jagabo's lines (see below)

Download ffmpeg if you don't have it already and extract the files and put the folder on the desktop or downloads.
https://www.videohelp.com/software/ffmpeg

Edit the txt file to add the path where your ffmpeg.exe is located and add pause at the bottom

"i:\bin\ffmpeg.exe" -y -benchmark -init_hw_device qsv=hw -filter_hw_device hw -v verbose ^
    -i %1 ^
    -vf "scale=720:-4:flags=spline,hqdn3d=1.0:1.0:1.0:1.0" ^
    -c:v libx264 -preset veryfast -crf 23 -g 50 ^
    -profile:v high -level:v 4.2 -g 50 -colorspace bt709 -color_range tv ^
    -acodec copy ^
    "%~dpn1.avc.mkv"
pause

Save the changes and rename the txt file to ffmpeg.bat (right click the file/properties and change the name in the box at the top)

Drag your video file onto the bat file's icon and it will reencode and store the new file in the same folder as the old.
It will open a CMD box and the progress can be seen. Any errors will also appear there.

[manono]

You didn't even mention what software you've tried. As already implied by El Heggunte (who wasn't trolling), you should do that first thing, rather than just saying, "No matter what I do...".

If you don't understand command line tools and can't be bothered to investigate and learn, then try VidCoder.

I want it to be an mp4 file. Also, WHERE do I put the file path ?

Just tried...I think. And it doesn't work. I dragged the video onto the icon and nothing happened except that it moved the file to the folder. Oh, well.

Another also...I changed the name of the file, but it was still a .txt file. It became ffmpeg.bat.txt

No it should be called ffmpeg.bat without the .txt extension
Make sure extensions are visible. In any Windows Explorer window, select view (at the top), options (right)/change folder and search options
View tab/deselect "hide extensions for known file types"

Here's a portion of my desktop with the bat file, right click, Edit and it opens in Notepad

On the otherhand, manono's choice of Vidcoder is a good choice if you don't want to be bothered with setting all this
up (it's easy to maintain/duplicate once you understand and get it working)

I did that exact thing and nothing happened. I'll try the vidcoder...

OK. It seems my rename example posted earlier doesn't work until you first deselect "hide file extensions for known file types" -
Windows protects the file types pretty well otherwise

I was able to rename the file, but dragging the video onto it didn't do anything. I'm about 60% into trying the vidcoder program, though.

You dragged your video onto the BAT file icon? Should have opened the CMD window and either process the file or give
an immediate error message.
If you want to pursue further, post this BAT file here to the thread and I'll take a look

Yeah. I changed it from .txt to .bat. Then, I pulled the video over top of it. The only thing that happened was it moved the video to the folder the .bat file was in. I tried attaching the .bat file but it says it's an invalid file.

Here's the file.

[davexnet]

It should be ffmpeg.bat, I've renamed it for you. You have to update the path to ffmpeg.exe as I showed earlier (on the first line),
also the hardcoding of the complete output file name on the last line will probably be OK, but it was the better the way it was;
the code generates an output name based the name of the source media file

it was named ffmpeg.bat, but this site wouldn't accept the file.

This is way more complicated than it should be. I was told to put the video path in the txt file, now I have to put the ffmpeg path in the file ?

[davexnet]

The first line must point to the ffmpeg.exe you downloaded and extracted into a folder somewhere.
Otherwise the command processor has nothing to execute when you drag a file to it.

In my system, ffmpeg.exe lives in i:\bin, edit your bat file accordingly

I agree, it's a bit complicated to set up for non-tech users.
But once you get it working, it's a very useful tool to have
