MP4 Tag Editor

[omidsolo]

Hey,
I need to edit the properties of an x265 MP4 file.
Built-in explorer does not show the advanced tags, I just see them using MediaInfo (installed by K-Lite)
So is there any free tool to edit those extra tags embedded into the MP4 video?

**Note: abcAvi does not work for x265 MP4/M4V
** MetadataTouch also does not open the ones I need.
** To be clear, I used HandBrake to encode a video and "Encoding settings:" fields has a huge list of switches, I need to remove that large field!

Thanks.

To be clear, I used HandBrake to encode a video and "Encoding settings:" fields has a huge list of switches, I need to remove that large field!

These are not mp4 tags but SEI informations in the video stream.
ffmpegs bitstream filters allow to remove the SEI info from H.264 and H.265 streams. Details about it can be found through the forum search or google.

[omidsolo]

Thanks mate, do you have the command line to remove em all?

[Selur]

For H.264:

"path to ffmpeg" -i "path to input" -c copy -bsf:v 'filter_units=remove_types=6' "path to stripped output"

one could remove the SEI data (which holds the 'Encoding settings'.
Note that the x264 authors want those information to be in the streams that are created with their encoder.

For H.265:
x265 authors allow to disable the creation of this information using '--no-info'
using

"path to ffmpeg" -i "path to input" -c copy -bsf:v 'filter_units=remove_types=39-40' "path to stripped output"

should remove the sei messages, see nal unit types in http://iphome.hhi.de/wiegand/assets/pdfs/2012_12_IEEE-HEVC-Overview.pdf

Hey
Thanks for your kind help, since it's x265 I used:

ffmpeg.exe -i "D:\bin\source.mp4" -c copy -bsf:v 'filter_units=remove_types=39-40' "D:\bin\target.mp4"

But I get:

Error parsing bitstream filter sequence ''filter_units=remove_types=39-40'': Bitstream filter not found

[Selur]

since it's x265 I used

remember to simply tell x265 to not create the info in the first place if you don't need/want it.

since you are on windows using quotes:

-bsf:v "filter_units=remove_types=39-40"

should help, assuming your ffmpeg build supports filter_units ("ffmpeg -bsfs" list the available bitstreamf ilters) which it should.

Hey thx indeed, and sorry if I'm noob at this
It worked, but the new file still have the huge "Encoding settings" following by tons of switches/parameters!
Any advise please?

[Selur]

That is strange since it does work fine here.

Are you sure you looked at the output and not the input when checking whether it worked?
(these 'Encoding settings' are SEI messages so the ffmpeg filter call should work without a problem)

[omidsolo]

Hey, thanks so much for the tip, unfortunately yeah I'm sure and both input/output still have that:

https://forum.videohelp.com/attachment.php?attachmentid=55664&stc=1&d=1603973088

[Selur]

Really strange,..
to make sure, that MediaInfo Tool you use doesn't cache the results by name, also try if the same happens if you use:

ffmpeg.exe -i "D:\bin\source.mp4" -c copy -bsf:v "filter_units=remove_types=39-40" "D:\bin\stripped.mp4"

if it's not a cache issue, I would need a !small! example file to look into it, since with the files I have here filter_units works fine.

[omidsolo]

Hey again. thx for the tip, seems not caching issue, also that happened with the new command, I'm uploading the video, and really thank you for the help, it's pretty important for me

[Selur]

you can attach a small sample here,...

[Selur]

Got your file, but got no clue why ffmpeg isn't working.
What does work is remuxing the whole thing with Hybrid.

• Start Hybrid
• open file
• set "Base->Processing->Video" to "passthrough"
• set "Base->Processing->Audio" to "passthrough all"
• set Output
• Create job
• Start job

Upon job creation, Hybrid creates the following calls:

• to extract the audio
  

  ffmpeg -y -threads 8 -i "C:\Users\Selur\Desktop\Documentary.mp4" -map 0:1 -vn -sn -acodec copy -map_metadata -1 -metadata encoding_tool="Hybrid 2020.10.29.1" "E:\Temp\iId_1_aid_0_2020-10-29@21_21_35_4010_01.aac"

• to extract the video
  

  MP4Box -raw 1 "C:\Users\Selur\Desktop\DOCUME~1.MP4" -out "E:\Temp\Documentary_2020-10-29@21_21_35_4010_02.265"

• to multiplex the raw streams

To lazy to investigate further why ffmpegs bitstream filter doesn't work.

Hey mate, I don't know how to thank you for your very great help
It worked great, perhaps ffmpeg has a bug or is not removing that intentionally!
Cheers ♥

My guess is that it's a bug.
